Some photos of my fine art photography hanging in the gallery for all my flickr fans! Thanks for the 120,000,000+ views y'all!
Setting up in a gallery was fun! It did not seem like work. :) I even got to drive to Home Depot & buy lumber (pine), hammers, nails, and a saw! I added a few dozen feet of new wooden strips to hang all the Hero's Journey Mythology photography--white strips and grey strips--cut them, nailed them up, and painted them so that we could fit all my fine art photography in the gallery! I told them I have even more on flickr if they want more photos--haha. :)
Some photographs are 13"x19" metallic prints on Kodak metallic paper mounted on 18"x24" matts in wood frames with 2.5" black, wood-grain borders, set behind anti-reflective, UV protective, museum glass! Awesome--everyone asks "why didn't you put these behind glass" because the anti-reflective museum glass is so clear! Other fine art photographs are 24" x 36" printed on canvas wraps, or 24" x 36" printed on canvas and front-mounted to plexiglass / acryllic (I love these! Great for HDR)! And the finest ones are 40" x 60" laser-printed on Fuji-crystal archival paper, front mounted to UV-protective acryllic / plexiglass, with a solid aluminum backing for durablity! Heavy, but nice! :) Also have a couple huge 40"x70" (the motorcycle in Venice and Corvette on the PCH) printed straight on a sheet of metal! Some were printed on Canon, some on Epson, and others on a laser printer so expensive it doesn't even have a name. :) I saw it in downtown LA--it was HUGE!
This is my first gallery show, and the funny thing is that while setting it up and adding all the carpentry/new wood strips, I shot more photography than usual, getting up every day at 5 AM to shoot the sunrise at around 6:30-6:45 AM. The Journey Never Ends! As Malibu faces South, the sun rises over the water this time of year, and sets over it too! So it keeps me busy as I hate missing the awesomely magical December cirrus cloud sunrises & sunsets, some of which you see hanging in the gallery, with many, many more to come!
Well, all the best on your epic hero's journey! The gallery is just below Bel Air Camera in Westwood, and if you ever want to meet up, drop me a line! :)
Happy Holidays & Best on Your Epic Hero's Journey!
P.S. (Some folks have asked me when I am going to have a goddess gallery show--soon! :)

A good looking project 😉 This German Aerospace Center, DLR-EAC Retinal Diagnostics project helps examine astronaut eyes on the International Space Station. With the help of an ophthalmic lens, which we attach to the camera of our tablets, and ESA - European Space Agency's ECOS operations support team on the ground we take and send images of our retina for analysis by experts 👀 These images are used to detect visual disorders that are common in space and to train an Artifical Intelligence (AI) model for future diagnosis. However, because this app is so compact and easy-to-use, it can also help in performing remote examinations and ensuring eye health in hard-to-reach places on Earth. www.esa.int/About_Us/EAC/Artificial_intelligence_for_eye_...

Arequipa, Peru.
**I lost my dear hat inside a Bolivian outhouse in the salt flats soon afterwards. It was one of those reversible cutie hats with big pom pom ties.
Oh... this is a long shot, but should anyone visit Peru in the near future... I'd love a replacement hat just like this one. It was the most comfy 'n warm 'n cozy hat... and it matched my alpaca wool llama-print socks perfectly! What to do... what to do...
Altitude sickness
From Wikipedia, the free encyclopedia
Altitude sickness, also known as acute mountain sickness (AMS), altitude illness, or soroche, is a pathological condition that is caused by acute exposure to low air pressure (usually outdoors at high altitudes). It commonly occurs above 2,400 metres (approximately 8,000 feet).[1] Acute mountain sickness can progress to high altitude pulmonary edema (HAPE) or high altitude cerebral edema (HACE).[2]
The cause of altitude sickness is still not understood. [3] It occurs in low atmospheric pressure conditions but not necessarily in low oxygen conditions at sea level pressure. Although treatable to some extent by the administration of oxygen, most of the symptoms do not appear to be caused by low oxygen, but rather by the low CO2 levels causing a rise in blood pH, alkalosis. The percentage of oxygen in air remains essentially constant with altitude at 21 percent, but the air pressure (and therefore the number of oxygen molecules) drops as altitude increases.[4] Altitude sickness usually does not affect persons traveling in aircraft because modern aircraft passenger compartments are pressurized.
A related condition,[citation needed] occurring only after prolonged exposure to high altitude, is chronic mountain sickness, also known as Monge's disease.
An unrelated condition, although often confused with altitude sickness, is dehydration, due to the higher rate of water vapor lost from the lungs at higher altitudes.
Introduction
High altitude or mountain sickness is defined when someone feels sick at high altitudes, such as in the mountains or any other altitude-related sicknesses. It is hard to determine who will be affected by altitude-sickness as there are no specific factors that compare with this susceptibility to altitude sickness. However, most people can climb up to 2500 meters (8000 feet) normally.
Generally, different people have different susceptibilities to altitude sickness. For some otherwise healthy people, Acute Mountain Sickness (AMS) can begin to appear at around 2000 meters (6,500 feet) above sea level, such as at many mountain ski resorts, equivalent to a pressure of 80 kPa. AMS is the most frequent type of altitude sickness encountered. Symptoms often manifest themselves 6-10 hours after ascent and generally subside in 1 to 2 days, but they occasionally develop into the more serious conditions. Symptoms include headache, fatigue, stomach illness, dizziness, and sleep disturbance. Exertion aggravates the symptoms.
High altitude pulmonary edema (HAPE) and cerebral edema (HACE) are the most ominous of these symptoms, while AMS, retinal hemorrhage, and peripheral edema are less severe forms of the disease. The rate of ascent, altitude attained, amount of physical activity at high altitude, as well as individual susceptibility, are contributing factors to the onset and severity of high-altitude illness.
Altitude sickness usually occurs following a rapid ascent and can usually be prevented by ascending slowly.[5] In most of these cases, the symptoms are temporary and usually abate as altitude acclimatisation occurs. However, in extreme cases, altitude sickness can be fatal.
The word "soroche" came from South America and originally meant "ore", because of an old, incorrect belief that it was caused by toxic emanations of ores in the Andes mountains.
Signs and symptoms
Headache is a primary symptom used to diagnose altitude sickness, although headache is also a symptom of dehydration. A headache occurring at an altitude above 2,400 meters (8000 feet = 76 kPa), combined with any one or more of the following symptoms, can indicate altitude sickness:
* Lack of appetite, nausea, or vomiting
* Fatigue or weakness
* Dizziness or light-headedness
* Insomnia
* Pins and needles
* Shortness of breath upon exertion
* Persistent rapid pulse
* Drowsiness
* General malaise
* Peripheral edema (swelling of hands, feet, and face).
Symptoms that may indicate life-threatening altitude sickness include:
* pulmonary edema (fluid in the lungs):-
o persistent dry cough
o fever
o shortness of breath even when resting
* cerebral edema (swelling of the brain):-
o headache that does not respond to analgesics
o unsteady gait
o increased vomiting
o gradual loss of consciousness.
Severe cases
The most serious symptoms of altitude sickness are due to edema (fluid accumulation in the tissues of the body). At very high altitude, humans can get either high altitude pulmonary edema (HAPE), or high altitude cerebral edema (HACE). The physiological cause of altitude-induced edema is not conclusively established. It is currently believed, however, that HACE is caused by local vasodilation of cerebral blood vessels in response to hypoxia, resulting in greater blood flow and, consequently, greater capillary pressures. On the other hand, HAPE may be due to general vasoconstriction in the pulmonary circulation (normally a response to regional ventilation-perfusion mismatches) which, with constant or increased cardiac output, also leads to increases in capillary pressures. For those suffering HACE, dexamethasone may provide temporary relief from symptoms in order to keep descending under their own power.
HAPE occurs in ~2% of those who are adjusting to altitudes of ~3000 m (10,000 feet = 70 kPa) or more. It can progress rapidly and is often fatal. Symptoms include fatigue, severe dyspnea at rest, and cough that is initially dry but may progress to produce pink, frothy sputum. Descent to lower altitudes alleviates the symptoms of HAPE.
HACE is a life threatening condition that can lead to coma or death. It occurs in about 1% of people adjusting to altitudes above ~2700 m (9,000 feet = 73 kPa). Symptoms include headache, fatigue, visual impairment, bladder dysfunction, bowel dysfunction, loss of coordination, paralysis on one side of the body, and confusion. Descent to lower altitudes may save those afflicted with HACE.
Prevention
Avoiding alcohol ingestion
As alcohol tends to dehydrate, avoidance in the first 24 hours at a higher altitude is optimal.
Strenous activity
People with recurrent AMS note that by avoiding strenuous activity such as skiing, hiking, etc in the first 24 hours at altitude reduces their problems.
Altitude acclimatization
Altitude acclimatisation is the process of adjusting to decreasing oxygen levels at higher elevations, in order to avoid altitude sickness. Once above approximately 3,000 meters (10,000 feet = 70 kPa), most climbers and high altitude trekkers follow the "golden rule" - climb high, sleep low.[6] For high altitude climbers, a typical acclimatization regime might be to stay a few days at a base camp, climb up to a higher camp (slowly), then return to base camp. A subsequent climb to the higher camp would then include an overnight stay. This process is then repeated a few times, each time extending the time spent at higher altitudes to let the body adjust to the oxygen level there, a process that involves the production of additional red blood cells. Once the climber has acclimatised to a given altitude, the process is repeated with camps placed at progressively higher elevations. The general rule of thumb is to not ascend more than 300 metres (1,000 feet) per day to sleep. That is, one can climb from 3,000 (10,000 feet = 70 kPa) to 4,500 metres (15,000 feet = 58 kPa) in one day, but one should then descend back to 3,300 metres (11,000 feet = 67.5 kPa) to sleep. This process cannot safely be rushed, and this explains why climbers need to spend days (or even weeks at times) acclimatising before attempting to climb a high peak. Simulated altitude equipment that produce hypoxic (reduced oxygen) air can be used to acclimate to altitude, reducing the total time required on the mountain itself.
Altitude acclimatization is necessary for some people who rapidly move from lower altitudes to more moderate altitudes, usually by aircraft and ground transportation over a few hours, such as from sea level to 7000 feet of many Colorado, USA mountain resorts. Stopping at an intermediate altitude overnight can reduce or eliminate a repeat episode of AMS.
Drugs
Acetazolamide may help some people to speed up the acclimatisation process when taken before arriving at altitude, and can treat mild cases of altitude sickness. A typical dose is 250mg twice daily starting the day before moving to altitude.
A single randomized controlled trial found that sumatriptan may help prevent altitude sickness.[7]
For centuries, indigenous cultures of the Altiplano, such as the Aymaras, have used coca leaves to treat mild altitude sickness.
Oxygen enrichment
In high-altitude conditions, oxygen enrichment can counteract the effects of altitude sickness, or hypoxia. A small amount of supplemental oxygen reduces the equivalent altitude in climate-controlled rooms. At 3,400 m (67 kPa), raising the oxygen concentration level by 5 percent via an oxygen concentrator and an existing ventilation system provides an effective altitude of 3,000 m (70 kPa), which is more tolerable for surface-dwellers.[8] The most effective source of supplemental oxygen at high altitude are oxygen concentrators that use vacuum swing adsorption (VSA) technology.[neutrality disputed] As opposed to generators that use pressure swing adsorption (PSA), VSA technology does not suffer from performance degradation at increased altitude. The lower air density actually facilitates the vacuum step process.
Other methods
Drinking plenty of water will also help in acclimatisation[9] to replace the fluids lost through heavier breathing in the thin, dry air found at altitude, although consuming excessive quantities ("over-hydration") has no benefits and may lead to hyponatremia.
Oxygen from gas bottles or liquid containers can be applied directly via a nasal cannula or mask. Oxygen concentrators based upon PSA, VSA, or VPSA can be used to generate the oxygen if electricity is available. Stationary oxygen concentrators typically use PSA technology, which has performance degradations at the lower barometric pressures at high altitudes. One way to compensate for the performance degradation is to utilize a concentrator with more flow capacity. There are also portable oxygen concentrators that can be used on vehicle DC power or on internal batteries, and at least one system commercially available measures and compensates for the altitude effect on its performance up to 4,000 meters (13,123 feet). The application of high-purity oxygen from one of these methods increases the partial pressure of oxygen by raising the FIO2 (fraction of inspired oxygen).
Treatment
The only reliable treatment and in many cases the only option available is to descend. Attempts to treat or stabilise the patient in situ at altitude is dangerous unless highly controlled and with good medical facilities. However, the following treatments have been used when the patient's location and circumstances permit:
* Oxygen may be used for mild to moderate AMS below 12,000 feet and is commonly provided by physicians at mountain resorts. Symptoms abate in 12-36 hours without the need to descend.
* For more serious cases of AMS, or where rapid descent is impractical, a Gamow bag, a portable plastic pressure bag inflated with a foot pump, can be used to reduce the effective altitude by as much as 1,500 meters (5,000 feet). A Gamow bag is generally used only as an aid to evacuate severe AMS patients not to treat them at altitude.
* Acetazolamide may assist in altitude aclimatisation but is not a reliable treatment for established cases of even mild altitude sickness.[10][11]
* Some claim that mild altitude sickness can be controlled by consciously taking 10-12 large, rapid breaths every 5 minutes, (hyperventilation) but this claim lacks both empirical evidence and a plausible medical reason as to why this should be effective.[citation needed] If overdone, this can remove too much carbon dioxide causing hypocapnia.
* The folk remedy for altitude sickness in Ecuador , Peru and Bolivia is a tea made from the coca plant. See mate de coca.
* Other treatments include injectable steroids to reduce pulmonary edema, this may buy time to descend but treats a symptom, it does not treat the underlying AMS.

From Wikipedia, the free encyclopedia
Albinism (from Latin albus, "white"; see extended etymology, also called achromia, achromasia, or achromatosis) is a congenital disorder characterized by the complete or partial absence of pigment in the skin, hair and eyes due to absence or defect of tyrosinase, a copper-containing enzyme involved in the production of melanin. Albinism results from inheritance of recessive gene alleles and is known to affect all vertebrates, including humans. While an organism with complete absence of melanin is called an albino (US /ælˈbaɪnoʊ/,[1] or UK /ælˈbiːnoʊ/)[2] an organism with only a diminished amount of melanin is described as albinoid.[3]
Albinism is associated with a number of vision defects, such as photophobia, nystagmus and astigmatism. Lack of skin pigmentation makes for more susceptibility to sunburn and skin cancers. In rare cases such as Chédiak–Higashi syndrome, albinism may be associated with deficiencies in the transportation of melanin granules. This also affects essential granules present in immune cells leading to increased susceptibility to infection.[4]
In humans, there are two principal types of albinism, oculocutaneous, affecting the eyes, skin and hair, and ocular affecting the eyes only.
Most oculocutaenous albinistic humans appear white or very pale as the melanin pigments responsible for brown, black, and some yellow colorations are not present. Ocular albinism results in pale blue eyes, and may require genetic testing to diagnose.
Because individuals with albinism have skin that entirely lacks the dark pigment melanin, which helps protect the skin from the sun's ultraviolet radiation, their skin can burn more easily from overexposure.[5]
The human eye normally produces enough pigment to color the iris blue, green or brown and lend opacity to the eye. However, there are cases in which the eyes of an albinistic person appear red, pink or purple, depending on the amount of pigment present, due to the red of retina being visible through the iris. Lack of pigment in the eyes also results in problems with vision, both related and unrelated to photosensitivity.
The albinistic are generally as healthy as the rest of the population (but see related disorders below), with growth and development occurring as normal, and albinism by itself does not cause mortality,[6] although the lack of pigment blocking ultraviolet radiation increases the risk of skin cancer and other problems.
Visual problems[edit source | editbeta]
Malian singer Salif Keita
Development of the optical system is highly dependent on the presence of melanin, and the reduction or absence of this pigment in albinistic individuals may lead to
Misrouting of the retinogeniculate projections, resulting in abnormal decussation (crossing) of optic nerve fibres[5]
Photophobia and decreased visual acuity due to light scattering within the eye (ocular straylight)[5][7]
Reduced visual acuity due to foveal hypoplasia and possibly light-induced retinal damage[5]
Eye conditions common in albinism include:
Nystagmus, irregular rapid movement of the eyes back and forth, or in circular motion.[5]
Astigmatism, irregular shaped cornea requiring additional cylindrical corrective lenses in spectacles.[8]
Amblyopia, decrease in acuity of one or both eyes due to poor transmission to the brain, often due to other conditions such as strabismus.[5]
Optic nerve hypoplasia, underdevelopment of the optic nerve
Some of the visual problems associated with albinism arise from a poorly developed retinal pigment epithelium (RPE) due to the lack of melanin.[citation needed] This degenerate RPE causes foveal hypoplasia (a failure in the development of normal foveae), which results in eccentric fixation and lower visual acuity, and often a minor level of strabismus.
The iris is a sphincter formed from pigmented tissue that contracts when the eye is exposed to bright light, to protect the retina by limiting the amount of light passing through the pupil. In low light conditions the iris relaxes to allow more light to enter the eye. In albinistic subjects, the iris does not have enough pigment to block the light, thus the decrease in pupil diameter is only partially successful in reducing the amount of light entering the eye.[citation needed] Additionally, the improper development of the RPE, which in normal eyes absorbs most of the reflected sunlight, further increases glare due to light scattering within the eye.[9] The resulting sensitivity (photophobia) generally leads to discomfort in bright light, but this can be reduced by the use of sunglasses and/or brimmed hats.[10]
Genetics[edit source | editbeta]
Most forms of albinism are the result of the biological inheritance of genetically recessive alleles (genes) passed from both parents of an individual, though some rare forms are inherited from only one parent. There are other genetic mutations which are proven to be associated with albinism. All alterations, however, lead to changes in melanin production in the body.[6][11]
The chance of offspring with albinism resulting from the pairing of an organism with albinism and one without albinism is low. However, because organisms can be carriers of genes for albinism without exhibiting any traits, albinistic offspring can be produced by two non-albinistic parents. Albinism usually occurs with equal frequency in both sexes.[6] An exception to this is ocular albinism, which it is passed on to offspring through X-linked inheritance. Thus, ocular albinism occurs more frequently in males as they have a single X and Y chromosome, unlike females, whose genetics are characterized by two X chromosomes.[12]
There are two different forms of albinism: a partial lack of the melanin is known as hypomelanism, or hypomelanosis and the total absence of melanin is known as amelanism or amelanosis.

Genetic testing can confirm albinism and what variety it is, but offers no medical benefits except in the cases of non-OCA disorders (see below) that cause albinism along with other medical problems which may be treatable. The symptoms of albinism can be treated by various methods detailed below.
Treatment[edit source | editbeta]
For the most part, treatment of the eye conditions consists of visual rehabilitation. Surgery is possible on the ocular muscles to decrease nystagmus, strabismus and common refractive errors like astigmatism.[5] Nystagmus-damping surgery can also be performed, to reduce the "shaking" of the eyes back and forth.[13] The effectiveness of all these procedures varies greatly and depends on individual circumstances.
Glasses and other vision aids, large-print materials as well as bright but angled reading lights, can help individuals with albinism, even though their vision cannot be corrected completely. Some people with albinism do well using bifocals (with a strong reading lens), prescription reading glasses, and/or hand-held devices such as magnifiers or monoculars.[10] Contact lenses may be colored to block light transmission through the iris. But in the case of nystagmus this is not possible, due to the irritation that is caused by the movement of the eyes. Some use bioptics, glasses which have small telescopes mounted on, in, or behind their regular lenses, so that they can look through either the regular lens or the telescope. Newer designs of bioptics use smaller light-weight lenses. Some US states allow the use of bioptic telescopes for driving motor vehicles. (See also NOAH bulletin "Low Vision Aids".)
Epidemiology[edit source | editbeta]
Albinism affects people of all ethnic backgrounds; its frequency worldwide is estimated to be approximately one in 17,000. Prevalence of the different forms of albinism varies considerably by population, and is highest overall in people of sub-Saharan African descent.[14]
Society and culture[edit source | editbeta]
Main articles: Persecution of people with albinism and Albinism in popular culture
In physical terms, humans with albinism commonly have visual problems and need sun protection. They often face social and cultural challenges (even threats), as the condition is often a source of ridicule, discrimination, or even fear and violence. Many cultures around the world have developed beliefs regarding people with albinism.
In African countries such as Tanzania[15] and Burundi,[16][17] there has been an unprecedented rise in witchcraft-related killings of albino people in recent years, because their body parts are used in potions sold by witchdoctors. Numerous authenticated incidents have occurred in Africa during the 21st Century.[18][19][20][21] For example, in Tanzania, in September 2009, three men were convicted of killing a 14-year-old albino boy and severing his legs in order to sell them for witchcraft purposes.[22] Again in Tanzania and Burundi in 2010, the murder and dismemberment of a kidnapped albino child was reported from the courts,[16] as part of a continuing problem. National Geographic estimates that in Tanzania a complete set of albino body parts is worth $75,000.[1]
Another harmful and false belief is that sex with an albinistic woman will cure a man of HIV. This has led, for example in Zimbabwe, to rapes (and subsequent HIV infection).[23]
Certain ethnic groups and insular areas exhibit heightened susceptibility to albinism, presumably due to genetic factors. These include notably the Native American Kuna and Zuni nations (respectively of Panama and New Mexico); Japan, in which one particular form of albinism is unusually common; and Ukerewe Island, the population of which shows a very high incidence of albinism.[24]
Famous people with albinism include historical figures such as Oxford don William Archibald Spooner; actor-comedian Victor Varnado; musicians such as Johnny and Edgar Winter, Salif Keita, Winston "Yellowman" Foster, Brother Ali, Sivuca, Willie "Piano Red" Perryman; and fashion models Connie Chiu and Shaun Ross. Emperor Seinei of Japan is thought to have been an albino because he was said to have been born with white hair.
In animals[edit source | editbeta]
Many animals with albinism lack their protective camouflage and are unable to conceal themselves from their predators or prey; the survival rate of animals with albinism in the wild is usually quite low.[25][26] However the novelty of albino animals has occasionally led to their protection by groups such as the Albino Squirrel Preservation Society.
In what used to be called "partial albinism" but is more often termed leucism there can be a single patch or patches of skin that lack melanin. Especially in albinistic birds and reptiles, ruddy and yellow hues or other colors may be present on the entire body or in patches (as is common among pigeons), because of the presence of other pigments unaffected by albinism such as porphyrins, pteridines and psittacins, as well as carotenoid pigments derived from the diet.
Intentionally bred albinistic strains of some animal species are commonly used as model organisms in biomedical study and experimentation, although some researchers have argued that they are not always the best choice.[27] Examples include the BALB/c mouse and Wistar and Sprague Dawley rat strains, while albino rabbits were historically used for Draize toxicity testing.[28] The yellow mutation in fruit flies is their version of albinism.
The incidence of albinism can be artificially increased in fish by exposing the eggs to heavy metals (arsenic, cadmium, copper, mercury, selenium, zinc).[29]
The eyes of an albino animal appear red because the colour of the red blood cells in the underlying retinal blood vessels shows through where there is no pigment to obscure it.
Famous albino animals include Migaloo, a humpback whale off the coast of Australia; Pinky, a bottlenose dolphin living in and around in Calcasieu Lake, Louisiana; Snowflake, a Barcelona Zoo gorilla; Snowflake, a Bristol Zoo penguin; and Mahpiya Ska (Sioux for "White Cloud"), a buffalo in Jamestown, North Dakota.[30] The inspiration for Herman Melville's novel Moby-Dick was a sperm whale known as Mocha Dick.

ESA astronaut Matthias Maurer demonstrates the DLR-EAC Retinal Diagnostics project. He posted these images to his social media on 4 April 2022 with the caption:
A good looking project 😉 This German Aerospace Center, DLR-EAC Retinal Diagnostics project helps examine astronaut eyes on the International Space Station. With the help of an ophthalmic lens, which we attach to the camera of our tablets, and ESA - European Space Agency's ECOS operations support team on the ground we take and send images of our retina for analysis by experts 👀 These images are used to detect visual disorders that are common in space and to train an Artifical Intelligence (AI) model for future diagnosis. However, because this app is so compact and easy-to-use, it can also help in performing remote examinations and ensuring eye health in hard-to-reach places on Earth. www.esa.int/About_Us/EAC/Artificial_intelligence_for_eye_...

I re-visited the female Net-casting spider shown below but it was nowhere to be seen. I did however find a male which is smaller and greyer. I hope to get some photos soon for comparison. This shot is the same spider shown below from a slightly different angle and a tighter crop of that scary head.
Of interest are the super sized posterior eyes which have excellent light gathering capability with an aperture equivalent (f/stop) of 0.58 (cat f/0.9 & owl f/1.1). The image is focussed onto a large, light-receptive retinal membrane (which is destroyed at dawn and renewed again each night). The two small saphire and ruby coloured bumps are the anterior eyes. The anterior eyes are the ones that are most developed in jumping spiders (Salticidae), see H. albovittatum above.
Deep within the vast tapestry of the cosmos, amidst the glittering stars and the enigmatic secrets of distant galaxies, exists a truly extraordinary being - the Alien Female. She stands as a testament to the boundless wonders of the universe, a marvel of advanced technology and biological artistry intertwined in perfect harmony. In this series of panels, we embark on a captivating journey to unravel the intricacies of her existence, from the remarkable head circuitry that serves as the core of her cognitive prowess to the marvels of her sensory systems and the remarkable energy sources that power her existence.
The head circuitry, a fusion of quantum computing and biological material, stands as the heart of her cognitive architecture. It bestows upon her an unparalleled processing speed, enabling her to process vast amounts of information in mere moments. What sets her apart, however, is the intuitive user interface that seamlessly interfaces with the exotic technologies scattered throughout the galaxies. It allows her to receive and transmit thoughts as data streams, facilitating instantaneous knowledge transfer and learning through neural downloads. It is a testament to the endless possibilities of blending science and nature.
Her vision systems, a marvel in themselves, comprise multi-layered retinal implants that not only grant her the ability to zoom to microscopic levels but also extend her vision into previously imperceptible electromagnetic spectrums. These implants are not merely tools for observation; they also serve as conduits for holographic projection and recording, functioning both as a diagnostic instrument and a means to chronicle her cosmic odyssey.
The auditory devices she possesses are engineered to detect a breathtakingly wide spectrum of sound waves, from the deepest subsonic frequencies to the highest ultrasonic notes. This remarkable technology enables her to communicate with species that convey messages beyond human auditory capacity. Furthermore, it allows her to pick up the subtle vibrations of interstellar matter, tuning her senses to the cosmic symphonies that resonate throughout the universe.
The energy management module that sustains her existence is nothing short of groundbreaking. It combines the forces of fusion, fission, and antimatter to create an energy source that borders on the inexhaustible. This core is encased within a protective dark energy field, shielding her biological systems from harm while optimizing energy consumption. It is a testament to her resilience and adaptability in the face of the cosmic challenges she encounters.
Her support structures are an intricate tapestry woven from bio-metal and genetically modified collagen. This combination creates a lightweight yet nearly indestructible skeletal framework. Her muscles are reinforced with nano-filaments that possess the remarkable ability to dynamically alter density and strength, allowing her to effortlessly adapt to the diverse environments and physical demands she encounters on her interstellar journeys.
The wonder of her skin integration lies in its ability to change texture and colour to match the surroundings, providing her with the ultimate camouflage. Embedded nanochips continuously monitor and adjust her body temperature, ensuring her comfort in even the most extreme environments. Moreover, they protect her against environmental hazards such as radiation and extreme temperatures, safeguarding her as she explores the far reaches of the universe.
Her internal systems are teeming with autonomous nanobots, guardians of cellular integrity and masters of pathogen combat. These tiny marvels also possess the extraordinary capability to perform surgical repairs internally, eliminating the need for external medical intervention. This enables her to achieve rapid healing and adapt seamlessly to new environments, a testament to her resilience and resourcefulness.
The communication modules integrated into her being are nothing short of awe-inspiring. They house built-in universal translators, drawing upon a vast database of millions of languages and dialects from across the galaxy. These modules enable her to engage in real-time interpretation and generation of languages, including those based on non-vocal expressions such as colour shifts and bioluminescence. With this remarkable capability, our Alien Female can effortlessly interact with a multitude of life forms, forging connections across the cosmos.
In this series of panels, we invite you to embark on a voyage of discovery as we delve deeper into each facet of the Alien Female's existence. Join us in unravelling the mysteries of her technological marvels and her place in the grand cosmic tapestry. Together, we shall celebrate the beauty of science, the artistry of biology, and the boundless wonders of the universe through the lens of the Alien Female's incredible being.

Chris Burden’s Urban Light sculpture is just outside the door of Los Angeles County Museum of Art. In January of 2019, Lorna and I were there and I made a couple of stereograms, from 2 different spots.
When I generated this picture, I somehow chose the left frame from from one and the right frame from the other. Then, I processed the image as an optimized anaglyph without knowing it.
The optimization process is sometimes used to suppress retinal conflict. I am interested in doing exactly the opposite. Visual subtexts can be brought to the surface by doing this. In this image, the red channel* acts as a sponge, soaking up imprints of both the right and left panes of the stereogram. Some of the light poles are lower than others. The steps crisscross. The angles of the light poles are different, echoing the step angles. The red channel shows the multiplicity of directions existing under the combined RBG image. You can see the red channel in the combined RBG in the palm trees where suddenly, some red lampposts appear. Balance has not been obtained, but under the surface, everything is there, struggling to happen. There is chaos everywhere, but the emerging order is clear.
Use red/cyan glasses to see the 3D.
*To see the red channel, use Photoshop or some other powerful graphics engine. You will find a section of the software that splits your image into RGB channels. There you can isolate the red channel and analyze it for yourself.

A while ago we got in touch with Sr. X and asked if he'd be interested in doing a collaboration with us. We'd always liked his style and thought we may well be able to have some fun with a bit of street work. After knocking a few ideas round between us we settled on the idea of a stare off using the same image of a rather angry man as our starting point and seeing where we'd end up each doing it in our own style. So, with a somewhat unnatural day of sunshine promised for Sunday we packed up the id-iomobile and set off for the East End with hope in our hearts.
We'd had to guesstimate the size of the gates based on a photo but it turns out that we'd got the measurement just about spot on. So far, so good. Once we'd made the requisite amount of mess for his face it was just a matter or adding the stencil again and getting some shading in there. Meanwhile, Sr. X was adding his signature paint splashes that give a certain motion to the whole thing. At this point I remembered the LED's we'd brought along so it was decided to have some laser eyes that would hopefully give the whole piece a bit of a lift when darkness fell. I'm not entirely sure how long they last but I'm hoping maybe a week or so (if they haven't been stolen or removed by that time). I'm not sure who's going to win the stare off but all the loser has got to look forward to is some permanent retinal damage...
Cheers

Jellyfish, also known sea jellies, are the medusa-phase of certain gelatinous members of the subphylum Medusozoa, which is a major part of the phylum Cnidaria.
Jellyfish are mainly free-swimming marine animals with umbrella-shaped bells and trailing tentacles, although a few are anchored to the seabed by stalks rather than being mobile. The bell can pulsate to provide propulsion for highly efficient locomotion. The tentacles are armed with stinging cells and may be used to capture prey and defend against predators. Jellyfish have a complex life cycle. The medusa is normally the sexual phase, which produces planula larvae; these then disperse widely and enter a sedentary polyp phase, before reaching sexual maturity.
Jellyfish are found all over the world, from surface waters to the deep sea. Scyphozoans (the "true jellyfish") are exclusively marine, but some hydrozoans with a similar appearance live in freshwater. Large, often colorful, jellyfish are common in coastal zones worldwide. The medusae of most species are fast-growing, and mature within a few months then die soon after breeding, but the polyp stage, attached to the seabed, may be much more long-lived. Jellyfish have been in existence for at least 500 million years, and possibly 700 million years or more, making them the oldest multi-organ animal group.
Jellyfish are eaten by humans in certain cultures. They are considered a delicacy in some Asian countries, where species in the Rhizostomeae order are pressed and salted to remove excess water. Australian researchers have described them as a "perfect food": sustainable and protein-rich but relatively low in food energy.
They are also used in research, where the green fluorescent protein used by some species to cause bioluminescence has been adapted as a fluorescent marker for genes inserted into other cells or organisms.
The stinging cells used by jellyfish to subdue their prey can injure humans. Thousands of swimmers worldwide are stung every year, with effects ranging from mild discomfort to serious injury or even death. When conditions are favourable, jellyfish can form vast swarms, which can be responsible for damage to fishing gear by filling fishing nets, and sometimes clog the cooling systems of power and desalination plants which draw their water from the sea.
Names
The name jellyfish, in use since 1796, has traditionally been applied to medusae and all similar animals including the comb jellies (ctenophores, another phylum). The term jellies or sea jellies is more recent, having been introduced by public aquaria in an effort to avoid use of the word "fish" with its modern connotation of an animal with a backbone, though shellfish, cuttlefish and starfish are not vertebrates either. In scientific literature, "jelly" and "jellyfish" have been used interchangeably. Many sources refer to only scyphozoans as "true jellyfish".
A group of jellyfish is called a "smack" or a "smuck".
Definition
The term jellyfish broadly corresponds to medusae, that is, a life-cycle stage in the Medusozoa. The American evolutionary biologist Paulyn Cartwright gives the following general definition:
Typically, medusozoan cnidarians have a pelagic, predatory jellyfish stage in their life cycle; staurozoans are the exceptions [as they are stalked].
The Merriam-Webster dictionary defines jellyfish as follows:
A free-swimming marine coelenterate that is the sexually reproducing form of a hydrozoan or scyphozoan and has a nearly transparent saucer-shaped body and extensible marginal tentacles studded with stinging cells.
Given that jellyfish is a common name, its mapping to biological groups is inexact. Some authorities have called the comb jellies and certain salps jellyfish, though other authorities state that neither of these are jellyfish, which they consider should be limited to certain groups within the medusozoa.
The non-medusozoan clades called jellyfish by some but not all authorities (both agreeing and disagreeing citations are given in each case) are indicated with on the following cladogram of the animal kingdom:
Jellyfish are not a clade, as they include most of the Medusozoa, barring some of the Hydrozoa. The medusozoan groups included by authorities are indicated on the following phylogenetic tree by the presence of citations. Names of included jellyfish, in English where possible, are shown in boldface; the presence of a named and cited example indicates that at least that species within its group has been called a jellyfish.
Taxonomy
The subphylum Medusozoa includes all cnidarians with a medusa stage in their life cycle. The basic cycle is egg, planula larva, polyp, medusa, with the medusa being the sexual stage. The polyp stage is sometimes secondarily lost. The subphylum include the major taxa, Scyphozoa (large jellyfish), Cubozoa (box jellyfish) and Hydrozoa (small jellyfish), and excludes Anthozoa (corals and sea anemones). This suggests that the medusa form evolved after the polyps. Medusozoans have tetramerous symmetry, with parts in fours or multiples of four.
The four major classes of medusozoan Cnidaria are:
Scyphozoa are sometimes called true jellyfish, though they are no more truly jellyfish than the others listed here. They have tetra-radial symmetry. Most have tentacles around the outer margin of the bowl-shaped bell, and long, oral arms around the mouth in the center of the subumbrella.
Cubozoa (box jellyfish) have a (rounded) box-shaped bell, and their velarium assists them to swim more quickly. Box jellyfish may be related more closely to scyphozoan jellyfish than either are to the Hydrozoa.
Hydrozoa medusae also have tetra-radial symmetry, nearly always have a velum (diaphragm used in swimming) attached just inside the bell margin, do not have oral arms, but a much smaller central stalk-like structure, the manubrium, with terminal mouth opening, and are distinguished by the absence of cells in the mesoglea. Hydrozoa show great diversity of lifestyle; some species maintain the polyp form for their entire life and do not form medusae at all (such as Hydra, which is hence not considered a jellyfish), and a few are entirely medusal and have no polyp form.
Staurozoa (stalked jellyfish) are characterized by a medusa form that is generally sessile, oriented upside down and with a stalk emerging from the apex of the "calyx" (bell), which attaches to the substrate. At least some Staurozoa also have a polyp form that alternates with the medusoid portion of the life cycle. Until recently, Staurozoa were classified within the Scyphozoa.
There are over 200 species of Scyphozoa, about 50 species of Staurozoa, about 50 species of Cubozoa, and the Hydrozoa includes about 1000–1500 species that produce medusae, but many more species that do not.
Fossil history
Since jellyfish have no hard parts, fossils are rare. The oldest unambiguous fossil of a free-swimming medusa is Burgessomedusa from the mid Cambrian Burgess Shale of Canada, which is likely either a stem group of box jellyfish (Cubozoa) or Acraspeda (the clade including Staurozoa, Cubozoa, and Scyphozoa). Other claimed records from the Cambrian of China and Utah in the United States are uncertain, and possibly represent ctenophores instead.
Anatomy
The main feature of a true jellyfish is the umbrella-shaped bell. This is a hollow structure consisting of a mass of transparent jelly-like matter known as mesoglea, which forms the hydrostatic skeleton of the animal. 95% or more of the mesogloea consists of water, but it also contains collagen and other fibrous proteins, as well as wandering amoebocytes which can engulf debris and bacteria. The mesogloea is bordered by the epidermis on the outside and the gastrodermis on the inside. The edge of the bell is often divided into rounded lobes known as lappets, which allow the bell to flex. In the gaps or niches between the lappets are dangling rudimentary sense organs known as rhopalia, and the margin of the bell often bears tentacles.
Anatomy of a scyphozoan jellyfish
On the underside of the bell is the manubrium, a stalk-like structure hanging down from the centre, with the mouth, which also functions as the anus, at its tip. There are often four oral arms connected to the manubrium, streaming away into the water below. The mouth opens into the gastrovascular cavity, where digestion takes place and nutrients are absorbed. This is subdivided by four thick septa into a central stomach and four gastric pockets. The four pairs of gonads are attached to the septa, and close to them four septal funnels open to the exterior, perhaps supplying good oxygenation to the gonads. Near the free edges of the septa, gastric filaments extend into the gastric cavity; these are armed with nematocysts and enzyme-producing cells and play a role in subduing and digesting the prey. In some scyphozoans, the gastric cavity is joined to radial canals which branch extensively and may join a marginal ring canal. Cilia in these canals circulate the fluid in a regular direction.
Discharge mechanism of a nematocyst
The box jellyfish is largely similar in structure. It has a squarish, box-like bell. A short pedalium or stalk hangs from each of the four lower corners. One or more long, slender tentacles are attached to each pedalium. The rim of the bell is folded inwards to form a shelf known as a velarium which restricts the bell's aperture and creates a powerful jet when the bell pulsates, allowing box jellyfish to swim faster than true jellyfish. Hydrozoans are also similar, usually with just four tentacles at the edge of the bell, although many hydrozoans are colonial and may not have a free-living medusal stage. In some species, a non-detachable bud known as a gonophore is formed that contains a gonad but is missing many other medusal features such as tentacles and rhopalia. Stalked jellyfish are attached to a solid surface by a basal disk, and resemble a polyp, the oral end of which has partially developed into a medusa with tentacle-bearing lobes and a central manubrium with four-sided mouth.
Most jellyfish do not have specialized systems for osmoregulation, respiration and circulation, and do not have a central nervous system. Nematocysts, which deliver the sting, are located mostly on the tentacles; true jellyfish also have them around the mouth and stomach. Jellyfish do not need a respiratory system because sufficient oxygen diffuses through the epidermis. They have limited control over their movement, but can navigate with the pulsations of the bell-like body; some species are active swimmers most of the time, while others largely drift. The rhopalia contain rudimentary sense organs which are able to detect light, water-borne vibrations, odour and orientation. A loose network of nerves called a "nerve net" is located in the epidermis. Although traditionally thought not to have a central nervous system, nerve net concentration and ganglion-like structures could be considered to constitute one in most species. A jellyfish detects stimuli, and transmits impulses both throughout the nerve net and around a circular nerve ring, to other nerve cells. The rhopalial ganglia contain pacemaker neurones which control swimming rate and direction.
In many species of jellyfish, the rhopalia include ocelli, light-sensitive organs able to tell light from dark. These are generally pigment spot ocelli, which have some of their cells pigmented. The rhopalia are suspended on stalks with heavy crystals at one end, acting like gyroscopes to orient the eyes skyward. Certain jellyfish look upward at the mangrove canopy while making a daily migration from mangrove swamps into the open lagoon, where they feed, and back again.
Box jellyfish have more advanced vision than the other groups. Each individual has 24 eyes, two of which are capable of seeing colour, and four parallel information processing areas that act in competition, supposedly making them one of the few kinds of animal to have a 360-degree view of its environment.
Box jellyfish eye
The study of jellyfish eye evolution is an intermediary to a better understanding of how visual systems evolved on Earth. Jellyfish exhibit immense variation in visual systems ranging from photoreceptive cell patches seen in simple photoreceptive systems to more derived complex eyes seen in box jellyfish. Major topics of jellyfish visual system research (with an emphasis on box jellyfish) include: the evolution of jellyfish vision from simple to complex visual systems), the eye morphology and molecular structures of box jellyfish (including comparisons to vertebrate eyes), and various uses of vision including task-guided behaviors and niche specialization.
Evolution
Experimental evidence for photosensitivity and photoreception in cnidarians antecedes the mid 1900s, and a rich body of research has since covered evolution of visual systems in jellyfish. Jellyfish visual systems range from simple photoreceptive cells to complex image-forming eyes. More ancestral visual systems incorporate extraocular vision (vision without eyes) that encompass numerous receptors dedicated to single-function behaviors. More derived visual systems comprise perception that is capable of multiple task-guided behaviors.
Although they lack a true brain, cnidarian jellyfish have a "ring" nervous system that plays a significant role in motor and sensory activity. This net of nerves is responsible for muscle contraction and movement and culminates the emergence of photosensitive structures. Across Cnidaria, there is large variation in the systems that underlie photosensitivity. Photosensitive structures range from non-specialized groups of cells, to more "conventional" eyes similar to those of vertebrates. The general evolutionary steps to develop complex vision include (from more ancestral to more derived states): non-directional photoreception, directional photoreception, low-resolution vision, and high-resolution vision. Increased habitat and task complexity has favored the high-resolution visual systems common in derived cnidarians such as box jellyfish.
Basal visual systems observed in various cnidarians exhibit photosensitivity representative of a single task or behavior. Extraocular photoreception (a form of non-directional photoreception), is the most basic form of light sensitivity and guides a variety of behaviors among cnidarians. It can function to regulate circadian rhythm (as seen in eyeless hydrozoans) and other light-guided behaviors responsive to the intensity and spectrum of light. Extraocular photoreception can function additionally in positive phototaxis (in planula larvae of hydrozoans), as well as in avoiding harmful amounts of UV radiation via negative phototaxis. Directional photoreception (the ability to perceive direction of incoming light) allows for more complex phototactic responses to light, and likely evolved by means of membrane stacking. The resulting behavioral responses can range from guided spawning events timed by moonlight to shadow responses for potential predator avoidance. Light-guided behaviors are observed in numerous scyphozoans including the common moon jelly, Aurelia aurita, which migrates in response to changes in ambient light and solar position even though they lack proper eyes.
The low-resolution visual system of box jellyfish is more derived than directional photoreception, and thus box jellyfish vision represents the most basic form of true vision in which multiple directional photoreceptors combine to create the first imaging and spatial resolution. This is different from the high-resolution vision that is observed in camera or compound eyes of vertebrates and cephalopods that rely on focusing optics. Critically, the visual systems of box jellyfish are responsible for guiding multiple tasks or behaviors in contrast to less derived visual systems in other jellyfish that guide single behavioral functions. These behaviors include phototaxis based on sunlight (positive) or shadows (negative), obstacle avoidance, and control of swim-pulse rate.
Box jellyfish possess "proper eyes" (similar to vertebrates) that allow them to inhabit environments that lesser derived medusae cannot. In fact, they are considered the only class in the clade Medusozoa that have behaviors necessitating spatial resolution and genuine vision. However, the lens in their eyes are more functionally similar to cup-eyes exhibited in low-resolution organisms, and have very little to no focusing capability. The lack of the ability to focus is due to the focal length exceeding the distance to the retina, thus generating unfocused images and limiting spatial resolution. The visual system is still sufficient for box jellyfish to produce an image to help with tasks such as object avoidance.
Utility as a model organism
Box jellyfish eyes are a visual system that is sophisticated in numerous ways. These intricacies include the considerable variation within the morphology of box jellyfishes' eyes (including their task/behavior specification), and the molecular makeup of their eyes including: photoreceptors, opsins, lenses, and synapses. The comparison of these attributes to more derived visual systems can allow for a further understanding of how the evolution of more derived visual systems may have occurred, and puts into perspective how box jellyfish can play the role as an evolutionary/developmental model for all visual systems.
Characteristics
Box jellyfish visual systems are both diverse and complex, comprising multiple photosystems. There is likely considerable variation in visual properties between species of box jellyfish given the significant inter-species morphological and physiological variation. Eyes tend to differ in size and shape, along with number of receptors (including opsins), and physiology across species of box jellyfish.
Box jellyfish have a series of intricate lensed eyes that are similar to those of more derived multicellular organisms such as vertebrates. Their 24 eyes fit into four different morphological categories. These categories consist of two large, morphologically different medial eyes (a lower and upper lensed eye) containing spherical lenses, a lateral pair of pigment slit eyes, and a lateral pair of pigment pit eyes. The eyes are situated on rhopalia (small sensory structures) which serve sensory functions of the box jellyfish and arise from the cavities of the exumbrella (the surface of the body) on the side of the bells of the jellyfish. The two large eyes are located on the mid-line of the club and are considered complex because they contain lenses. The four remaining eyes lie laterally on either side of each rhopalia and are considered simple. The simple eyes are observed as small invaginated cups of epithelium that have developed pigmentation. The larger of the complex eyes contains a cellular cornea created by a mono ciliated epithelium, cellular lens, homogenous capsule to the lens, vitreous body with prismatic elements, and a retina of pigmented cells. The smaller of the complex eyes is said to be slightly less complex given that it lacks a capsule but otherwise contains the same structure as the larger eye.
Box jellyfish have multiple photosystems that comprise different sets of eyes. Evidence includes immunocytochemical and molecular data that show photopigment differences among the different morphological eye types, and physiological experiments done on box jellyfish to suggest behavioral differences among photosystems. Each individual eye type constitutes photosystems that work collectively to control visually guided behaviors.
Box jellyfish eyes primarily use c-PRCs (ciliary photoreceptor cells) similar to that of vertebrate eyes. These cells undergo phototransduction cascades (process of light absorption by photoreceptors) that are triggered by c-opsins. Available opsin sequences suggest that there are two types of opsins possessed by all cnidarians including an ancient phylogenetic opsin, and a sister ciliary opsin to the c-opsins group. Box jellyfish could have both ciliary and cnidops (cnidarian opsins), which is something not previously believed to appear in the same retina. Nevertheless, it is not entirely evident whether cnidarians possess multiple opsins that are capable of having distinctive spectral sensitivities.
Comparison with other organisms
Comparative research on genetic and molecular makeup of box jellyfishes' eyes versus more derived eyes seen in vertebrates and cephalopods focuses on: lenses and crystallin composition, synapses, and Pax genes and their implied evidence for shared primordial (ancestral) genes in eye evolution.
Box jellyfish eyes are said to be an evolutionary/developmental model of all eyes based on their evolutionary recruitment of crystallins and Pax genes. Research done on box jellyfish including Tripedalia cystophora has suggested that they possess a single Pax gene, PaxB. PaxB functions by binding to crystallin promoters and activating them. PaxB in situ hybridization resulted in PaxB expression in the lens, retina, and statocysts. These results and the rejection of the prior hypothesis that Pax6 was an ancestral Pax gene in eyes has led to the conclusion that PaxB was a primordial gene in eye evolution, and that the eyes of all organisms likely share a common ancestor.
The lens structure of box jellyfish appears very similar to those of other organisms, but the crystallins are distinct in both function and appearance. Weak reactions were seen within the sera and there were very weak sequence similarities within the crystallins among vertebrate and invertebrate lenses. This is likely due to differences in lower molecular weight proteins and the subsequent lack of immunological reactions with antisera that other organisms' lenses exhibit.
All four of the visual systems of box jellyfish species investigated with detail (Carybdea marsupialis, Chiropsalmus quadrumanus, Tamoya haplonema and Tripedalia cystophora) have invaginated synapses, but only in the upper and lower lensed eyes. Different densities were found between the upper and lower lenses, and between species. Four types of chemical synapses have been discovered within the rhopalia which could help in understanding neural organization including: clear unidirectional, dense-core unidirectional, clear bidirectional, and clear and dense-core bidirectional. The synapses of the lensed eyes could be useful as markers to learn more about the neural circuit in box jellyfish retinal areas.
Evolution as a response to natural stimuli
The primary adaptive responses to environmental variation observed in box jellyfish eyes include pupillary constriction speeds in response to light environments, as well as photoreceptor tuning and lens adaptations to better respond to shifts between light environments and darkness. Interestingly, some box jellyfish species' eyes appear to have evolved more focused vision in response to their habitat.
Pupillary contraction appears to have evolved in response to variation in the light environment across ecological niches across three species of box jellyfish (Chironex fleckeri, Chiropsella bronzie, and Carukia barnesi). Behavioral studies suggest that faster pupil contraction rates allow for greater object avoidance, and in fact, species with more complex habitats exhibit faster rates. Ch. bronzie inhabit shallow beach fronts that have low visibility and very few obstacles, thus, faster pupil contraction in response to objects in their environment is not important. Ca. barnesi and Ch. fleckeri are found in more three-dimensionally complex environments like mangroves with an abundance of natural obstacles, where faster pupil contraction is more adaptive. Behavioral studies support the idea that faster pupillary contraction rates assist with obstacle avoidance as well as depth adjustments in response to differing light intensities.
Light/dark adaptation via pupillary light reflexes is an additional form of an evolutionary response to the light environment. This relates to the pupil's response to shifts between light intensity (generally from sunlight to darkness). In the process of light/dark adaptation, the upper and lower lens eyes of different box jellyfish species vary in specific function. The lower lens-eyes contain pigmented photoreceptors and long pigment cells with dark pigments that migrate on light/dark adaptation, while the upper-lens eyes play a concentrated role in light direction and phototaxis given that they face upward towards the water surface (towards the sun or moon). The upper lens of Ch. bronzie does not exhibit any considerable optical power while Tr. cystophora (a box jellyfish species that tends to live in mangroves) does. The ability to use light to visually guide behavior is not of as much importance to Ch. bronzie as it is to species in more obstacle-filled environments. Differences in visually guided behavior serve as evidence that species that share the same number and structure of eyes can exhibit differences in how they control behavior.
Largest and smallest
Jellyfish range from about one millimeter in bell height and diameter, to nearly 2 metres (6+1⁄2 ft) in bell height and diameter; the tentacles and mouth parts usually extend beyond this bell dimension.
The smallest jellyfish are the peculiar creeping jellyfish in the genera Staurocladia and Eleutheria, which have bell disks from 0.5 millimetres (1⁄32 in) to a few millimeters in diameter, with short tentacles that extend out beyond this, which these jellyfish use to move across the surface of seaweed or the bottoms of rocky pools; many of these tiny creeping jellyfish cannot be seen in the field without a hand lens or microscope. They can reproduce asexually by fission (splitting in half). Other very small jellyfish, which have bells about one millimeter, are the hydromedusae of many species that have just been released from their parent polyps; some of these live only a few minutes before shedding their gametes in the plankton and then dying, while others will grow in the plankton for weeks or months. The hydromedusae Cladonema radiatum and Cladonema californicum are also very small, living for months, yet never growing beyond a few mm in bell height and diameter.
The lion's mane jellyfish, Cyanea capillata, was long-cited as the largest jellyfish, and arguably the longest animal in the world, with fine, thread-like tentacles that may extend up to 36.5 m (119 ft 9 in) long (though most are nowhere near that large). They have a moderately painful, but rarely fatal, sting. The increasingly common giant Nomura's jellyfish, Nemopilema nomurai, found in some, but not all years in the waters of Japan, Korea and China in summer and autumn is another candidate for "largest jellyfish", in terms of diameter and weight, since the largest Nomura's jellyfish in late autumn can reach 2 m (6 ft 7 in) in bell (body) diameter and about 200 kg (440 lb) in weight, with average specimens frequently reaching 0.9 m (2 ft 11 in) in bell diameter and about 150 kg (330 lb) in weight. The large bell mass of the giant Nomura's jellyfish can dwarf a diver and is nearly always much greater than the Lion's Mane, whose bell diameter can reach 1 m (3 ft 3 in).
The rarely encountered deep-sea jellyfish Stygiomedusa gigantea is another candidate for "largest jellyfish", with its thick, massive bell up to 100 cm (3 ft 3 in) wide, and four thick, "strap-like" oral arms extending up to 6 m (19+1⁄2 ft) in length, very different from the typical fine, threadlike tentacles that rim the umbrella of more-typical-looking jellyfish, including the Lion's Mane.
Desmonema glaciale, which lives in the Antarctic region, can reach a very large size (several meters). Purple-striped jelly (Chrysaora colorata) can also be extremely long (up to 15 feet).
Life history and behavior
Life cycle
Jellyfish have a complex life cycle which includes both sexual and asexual phases, with the medusa being the sexual stage in most instances. Sperm fertilize eggs, which develop into larval planulae, become polyps, bud into ephyrae and then transform into adult medusae. In some species certain stages may be skipped.
Upon reaching adult size, jellyfish spawn regularly if there is a sufficient supply of food. In most species, spawning is controlled by light, with all individuals spawning at about the same time of day; in many instances this is at dawn or dusk. Jellyfish are usually either male or female (with occasional hermaphrodites). In most cases, adults release sperm and eggs into the surrounding water, where the unprotected eggs are fertilized and develop into larvae. In a few species, the sperm swim into the female's mouth, fertilizing the eggs within her body, where they remain during early development stages. In moon jellies, the eggs lodge in pits on the oral arms, which form a temporary brood chamber for the developing planula larvae.
The planula is a small larva covered with cilia. When sufficiently developed, it settles onto a firm surface and develops into a polyp. The polyp generally consists of a small stalk topped by a mouth that is ringed by upward-facing tentacles. The polyps resemble those of closely related anthozoans, such as sea anemones and corals. The jellyfish polyp may be sessile, living on the bottom, boat hulls or other substrates, or it may be free-floating or attached to tiny bits of free-living plankton or rarely, fish or other invertebrates. Polyps may be solitary or colonial. Most polyps are only millimetres in diameter and feed continuously. The polyp stage may last for years.
After an interval and stimulated by seasonal or hormonal changes, the polyp may begin reproducing asexually by budding and, in the Scyphozoa, is called a segmenting polyp, or a scyphistoma. Budding produces more scyphistomae and also ephyrae. Budding sites vary by species; from the tentacle bulbs, the manubrium (above the mouth), or the gonads of hydromedusae. In a process known as strobilation, the polyp's tentacles are reabsorbed and the body starts to narrow, forming transverse constrictions, in several places near the upper extremity of the polyp. These deepen as the constriction sites migrate down the body, and separate segments known as ephyra detach. These are free-swimming precursors of the adult medusa stage, which is the life stage that is typically identified as a jellyfish. The ephyrae, usually only a millimeter or two across initially, swim away from the polyp and grow. Limnomedusae polyps can asexually produce a creeping frustule larval form, which crawls away before developing into another polyp. A few species can produce new medusae by budding directly from the medusan stage. Some hydromedusae reproduce by fission.
Lifespan
Little is known of the life histories of many jellyfish as the places on the seabed where the benthic forms of those species live have not been found. However, an asexually reproducing strobila form can sometimes live for several years, producing new medusae (ephyra larvae) each year.
An unusual species, Turritopsis dohrnii, formerly classified as Turritopsis nutricula, might be effectively immortal because of its ability under certain circumstances to transform from medusa back to the polyp stage, thereby escaping the death that typically awaits medusae post-reproduction if they have not otherwise been eaten by some other organism. So far this reversal has been observed only in the laboratory.
Locomotion
Jellyfish locomotion is highly efficient. Muscles in the jellylike bell contract, setting up a start vortex and propelling the animal. When the contraction ends, the bell recoils elastically, creating a stop vortex with no extra energy input.
Using the moon jelly Aurelia aurita as an example, jellyfish have been shown to be the most energy-efficient swimmers of all animals. They move through the water by radially expanding and contracting their bell-shaped bodies to push water behind them. They pause between the contraction and expansion phases to create two vortex rings. Muscles are used for the contraction of the body, which creates the first vortex and pushes the animal forward, but the mesoglea is so elastic that the expansion is powered exclusively by relaxing the bell, which releases the energy stored from the contraction. Meanwhile, the second vortex ring starts to spin faster, sucking water into the bell and pushing against the centre of the body, giving a secondary and "free" boost forward. The mechanism, called passive energy recapture, only works in relatively small jellyfish moving at low speeds, allowing the animal to travel 30 percent farther on each swimming cycle. Jellyfish achieved a 48 percent lower cost of transport (food and oxygen intake versus energy spent in movement) than other animals in similar studies. One reason for this is that most of the gelatinous tissue of the bell is inactive, using no energy during swimming.
Ecology
Diet
Jellyfish are, like other cnidarians, generally carnivorous (or parasitic), feeding on planktonic organisms, crustaceans, small fish, fish eggs and larvae, and other jellyfish, ingesting food and voiding undigested waste through the mouth. They hunt passively using their tentacles as drift lines, or sink through the water with their tentacles spread widely; the tentacles, which contain nematocysts to stun or kill the prey, may then flex to help bring it to the mouth. Their swimming technique also helps them to capture prey; when their bell expands it sucks in water which brings more potential prey within reach of the tentacles.
A few species such as Aglaura hemistoma are omnivorous, feeding on microplankton which is a mixture of zooplankton and phytoplankton (microscopic plants) such as dinoflagellates. Others harbour mutualistic algae (Zooxanthellae) in their tissues; the spotted jellyfish (Mastigias papua) is typical of these, deriving part of its nutrition from the products of photosynthesis, and part from captured zooplankton. The upside-down jellyfish (Cassiopea andromeda) also has a symbiotic relationship with microalgae, but captures tiny animals to supplement their diet. This is done by releasing tiny balls of living cells composed of mesoglea. These use cilia to drive them through water and stinging cells which stun the prey. The blobs also seems to have digestive capabilities.
Predation
Other species of jellyfish are among the most common and important jellyfish predators. Sea anemones may eat jellyfish that drift into their range. Other predators include tunas, sharks, swordfish, sea turtles and penguins. Jellyfish washed up on the beach are consumed by foxes, other terrestrial mammals and birds. In general however, few animals prey on jellyfish; they can broadly be considered to be top predators in the food chain. Once jellyfish have become dominant in an ecosystem, for example through overfishing which removes predators of jellyfish larvae, there may be no obvious way for the previous balance to be restored: they eat fish eggs and juvenile fish, and compete with fish for food, preventing fish stocks from recovering.
Symbiosis
Some small fish are immune to the stings of the jellyfish and live among the tentacles, serving as bait in a fish trap; they are safe from potential predators and are able to share the fish caught by the jellyfish. The cannonball jellyfish has a symbiotic relationship with ten different species of fish, and with the longnose spider crab, which lives inside the bell, sharing the jellyfish's food and nibbling its tissues.
Main article: Jellyfish bloom
Jellyfish form large masses or blooms in certain environmental conditions of ocean currents, nutrients, sunshine, temperature, season, prey availability, reduced predation and oxygen concentration. Currents collect jellyfish together, especially in years with unusually high populations. Jellyfish can detect marine currents and swim against the current to congregate in blooms. Jellyfish are better able to survive in nutrient-rich, oxygen-poor water than competitors, and thus can feast on plankton without competition. Jellyfish may also benefit from saltier waters, as saltier waters contain more iodine, which is necessary for polyps to turn into jellyfish. Rising sea temperatures caused by climate change may also contribute to jellyfish blooms, because many species of jellyfish are able to survive in warmer waters. Increased nutrients from agricultural or urban runoff with nutrients including nitrogen and phosphorus compounds increase the growth of phytoplankton, causing eutrophication and algal blooms. When the phytoplankton die, they may create dead zones, so-called because they are hypoxic (low in oxygen). This in turn kills fish and other animals, but not jellyfish, allowing them to bloom. Jellyfish populations may be expanding globally as a result of land runoff and overfishing of their natural predators. Jellyfish are well placed to benefit from disturbance of marine ecosystems. They reproduce rapidly; they prey upon many species, while few species prey on them; and they feed via touch rather than visually, so they can feed effectively at night and in turbid waters. It may be difficult for fish stocks to re-establish themselves in marine ecosystems once they have become dominated by jellyfish, because jellyfish feed on plankton, which includes fish eggs and larvae.
As suspected at the turn of this century, jellyfish blooms are increasing in frequency. Between 2013 and 2020 the Mediterranean Science Commission monitored on a weekly basis the frequency of such outbreaks in coastal waters from Morocco to the Black Sea, revealing a relatively high frequency of these blooms nearly all year round, with peaks observed from March to July and often again in the autumn. The blooms are caused by different jellyfish species, depending on their localisation within the Basin: one observes a clear dominance of Pelagia noctiluca and Velella velella outbreaks in the western Mediterranean, of Rhizostoma pulmo and Rhopilema nomadica outbreaks in the eastern Mediterranean, and of Aurelia aurita and Mnemiopsis leidyi outbreaks in the Black Sea.
Some jellyfish populations that have shown clear increases in the past few decades are invasive species, newly arrived from other habitats: examples include the Black Sea, Caspian Sea, Baltic Sea, central and eastern Mediterranean, Hawaii, and tropical and subtropical parts of the West Atlantic (including the Caribbean, Gulf of Mexico and Brazil).
Jellyfish blooms can have significant impact on community structure. Some carnivorous jellyfish species prey on zooplankton while others graze on primary producers. Reductions in zooplankton and ichthyoplankton due to a jellyfish bloom can ripple through the trophic levels. High-density jellyfish populations can outcompete other predators and reduce fish recruitment. Increased grazing on primary producers by jellyfish can also interrupt energy transfer to higher trophic levels.
During blooms, jellyfish significantly alter the nutrient availability in their environment. Blooms require large amounts of available organic nutrients in the water column to grow, limiting availability for other organisms. Some jellyfish have a symbiotic relationship with single-celled dinoflagellates, allowing them to assimilate inorganic carbon, phosphorus, and nitrogen creating competition for phytoplankton. Their large biomass makes them an important source of dissolved and particulate organic matter for microbial communities through excretion, mucus production, and decomposition. The microbes break down the organic matter into inorganic ammonium and phosphate. However, the low carbon availability shifts the process from production to respiration creating low oxygen areas making the dissolved inorganic nitrogen and phosphorus largely unavailable for primary production.
These blooms have very real impacts on industries. Jellyfish can outcompete fish by utilizing open niches in over-fished fisheries. Catch of jellyfish can strain fishing gear and lead to expenses relating to damaged gear. Power plants have been shut down due to jellyfish blocking the flow of cooling water. Blooms have also been harmful for tourism, causing a rise in stings and sometimes the closure of beaches.
Jellyfish form a component of jelly-falls, events where gelatinous zooplankton fall to the seafloor, providing food for the benthic organisms there. In temperate and subpolar regions, jelly-falls usually follow immediately after a bloom.
Habitats
Most jellyfish are marine animals, although a few hydromedusae inhabit freshwater. The best known freshwater example is the cosmopolitan hydrozoan jellyfish, Craspedacusta sowerbii. It is less than an inch (2.5 cm) in diameter, colorless and does not sting. Some jellyfish populations have become restricted to coastal saltwater lakes, such as Jellyfish Lake in Palau. Jellyfish Lake is a marine lake where millions of golden jellyfish (Mastigias spp.) migrate horizontally across the lake daily.
Although most jellyfish live well off the ocean floor and form part of the plankton, a few species are closely associated with the bottom for much of their lives and can be considered benthic. The upside-down jellyfish in the genus Cassiopea typically lie on the bottom of shallow lagoons where they sometimes pulsate gently with their umbrella top facing down. Even some deep-sea species of hydromedusae and scyphomedusae are usually collected on or near the bottom. All of the stauromedusae are found attached to either seaweed or rocky or other firm material on the bottom.
Some species explicitly adapt to tidal flux. In Roscoe Bay, jellyfish ride the current at ebb tide until they hit a gravel bar, and then descend below the current. They remain in still waters until the tide rises, ascending and allowing it to sweep them back into the bay. They also actively avoid fresh water from mountain snowmelt, diving until they find enough salt.
Parasites
Jellyfish are hosts to a wide variety of parasitic organisms. They act as intermediate hosts of endoparasitic helminths, with the infection being transferred to the definitive host fish after predation. Some digenean trematodes, especially species in the family Lepocreadiidae, use jellyfish as their second intermediate hosts. Fish become infected by the trematodes when they feed on infected jellyfish.
Relation to humans
Jellyfish have long been eaten in some parts of the world. Fisheries have begun harvesting the American cannonball jellyfish, Stomolophus meleagris, along the southern Atlantic coast of the United States and in the Gulf of Mexico for export to Asia.
Jellyfish are also harvested for their collagen, which is being investigated for use in a variety of applications including the treatment of rheumatoid arthritis.
Aquaculture and fisheries of other species often suffer severe losses – and so losses of productivity – due to jellyfish.
Products
Main article: Jellyfish as food
In some countries, including China, Japan, and Korea, jellyfish are a delicacy. The jellyfish is dried to prevent spoiling. Only some 12 species of scyphozoan jellyfish belonging to the order Rhizostomeae are harvested for food, mostly in southeast Asia. Rhizostomes, especially Rhopilema esculentum in China (海蜇 hǎizhé, 'sea stingers') and Stomolophus meleagris (cannonball jellyfish) in the United States, are favored because of their larger and more rigid bodies and because their toxins are harmless to humans.
Traditional processing methods, carried out by a jellyfish master, involve a 20- to 40-day multi-phase procedure in which, after removing the gonads and mucous membranes, the umbrella and oral arms are treated with a mixture of table salt and alum, and compressed. Processing makes the jellyfish drier and more acidic, producing a crisp texture. Jellyfish prepared this way retain 7–10% of their original weight, and the processed product consists of approximately 94% water and 6% protein. Freshly processed jellyfish has a white, creamy color and turns yellow or brown during prolonged storage.
In China, processed jellyfish are desalted by soaking in water overnight and eaten cooked or raw. The dish is often served shredded with a dressing of oil, soy sauce, vinegar and sugar, or as a salad with vegetables. In Japan, cured jellyfish are rinsed, cut into strips and served with vinegar as an appetizer. Desalted, ready-to-eat products are also available.
Biotechnology
The hydromedusa Aequorea victoria was the source of green fluorescent protein, studied for its role in bioluminescence and later for use as a marker in genetic engineering.
Pliny the Elder reported in his Natural History that the slime of the jellyfish "Pulmo marinus" produced light when rubbed on a walking stick.
In 1961, Osamu Shimomura extracted green fluorescent protein (GFP) and another bioluminescent protein, called aequorin, from the large and abundant hydromedusa Aequorea victoria, while studying photoproteins that cause bioluminescence in this species. Three decades later, Douglas Prasher sequenced and cloned the gene for GFP. Martin Chalfie figured out how to use GFP as a fluorescent marker of genes inserted into other cells or organisms. Roger Tsien later chemically manipulated GFP to produce other fluorescent colors to use as markers. In 2008, Shimomura, Chalfie and Tsien won the Nobel Prize in Chemistry for their work with GFP. Man-made GFP became widely used as a fluorescent tag to show which cells or tissues express specific genes. The genetic engineering technique fuses the gene of interest to the GFP gene. The fused DNA is then put into a cell, to generate either a cell line or (via IVF techniques) an entire animal bearing the gene. In the cell or animal, the artificial gene turns on in the same tissues and the same time as the normal gene, making a fusion of the normal protein with GFP attached to the end, illuminating the animal or cell reveals what tissues express that protein—or at what stage of development. The fluorescence shows where the gene is expressed.
Aquarium display
Jellyfish are displayed in many public aquariums. Often the tank's background is blue and the animals are illuminated by side light, increasing the contrast between the animal and the background. In natural conditions, many jellies are so transparent that they are nearly invisible. Jellyfish are not adapted to closed spaces. They depend on currents to transport them from place to place. Professional exhibits as in the Monterey Bay Aquarium feature precise water flows, typically in circular tanks to avoid trapping specimens in corners. The outflow is spread out over a large surface area and the inflow enters as a sheet of water in front of the outflow, so the jellyfish do not get sucked into it. As of 2009, jellyfish were becoming popular in home aquariums, where they require similar equipment.
Stings
Jellyfish are armed with nematocysts, a type of specialized stinging cell. Contact with a jellyfish tentacle can trigger millions of nematocysts to pierce the skin and inject venom, but only some species' venom causes an adverse reaction in humans. In a study published in Communications Biology, researchers found a jellyfish species called Cassiopea xamachana which when triggered will release tiny balls of cells that swim around the jellyfish stinging everything in their path. Researchers described these as "self-propelling microscopic grenades" and named them cassiosomes.
The effects of stings range from mild discomfort to extreme pain and death. Most jellyfish stings are not deadly, but stings of some box jellyfish (Irukandji jellyfish), such as the sea wasp, can be deadly. Stings may cause anaphylaxis (a form of shock), which can be fatal. Jellyfish kill 20 to 40 people a year in the Philippines alone. In 2006 the Spanish Red Cross treated 19,000 stung swimmers along the Costa Brava.
Vinegar (3–10% aqueous acetic acid) may help with box jellyfish stings but not the stings of the Portuguese man o' war. Clearing the area of jelly and tentacles reduces nematocyst firing. Scraping the affected skin, such as with the edge of a credit card, may remove remaining nematocysts. Once the skin has been cleaned of nematocysts, hydrocortisone cream applied locally reduces pain and inflammation. Antihistamines may help to control itching. Immunobased antivenins are used for serious box jellyfish stings.
In Elba Island and Corsica dittrichia viscosa is now used by residents and tourists to heal stings from jellyfish, bees and wasps pressing fresh leaves on the skin with quick results.
Mechanical issues
Jellyfish in large quantities can fill and split fishing nets and crush captured fish. They can clog cooling equipment, having disabled power stations in several countries; jellyfish caused a cascading blackout in the Philippines in 1999, as well as damaging the Diablo Canyon Power Plant in California in 2008. They can also stop desalination plants and ships' engines.

Miracle of the eyes

In order to better understand the perfection of God's creation, look at only a few of the millions of other examples of His art. As it says in Qur'an, all creatures are under His complete control:
. There is no creature He does not hold by the forelock. (Qur'an, 11: 56)
A countless number of organisms are living on this planet; and millions of different insect species alone.Of all the different types of eye, the human eye is the most superior overall, although the eyes of some species boast of features that are superior to those of humans. There are as many different types of eye as there are species, and we have already shown how impossible it is for such a variety to evolve through mutations and natural selection.
God has given every organism an eye that suits their lifestyle and feeding habits. In this section, we'll examine the eye structures of many different species.
Insect Eyes
Insects view the world through thousands of tiny eyes.
Compared to human eyes, the eyes of insects are considerably different. Their structures come in one of two types, simple or complex.
Simple-structured eyes are round and small, capable only of separating light and dark. Compound eyes, on the other hand, are larger and more complex, made up of hundreds of small pieces. Each "piece" is actually a small eye because it contains light sensitivecells, a lens, and connections to the brain.
As mentioned before, a human eye's lens can change shape, letting us focus on objects at various distances. The lens in an insect's eye cannot change shape, however, and so insects cannot focus.
The compound eye works by each of the eye's six-sided compartments (called ommatidia) detecting a tiny portion of the visual field. The information from each ommatidium is then combined, like pieces of a mosaic, to form a single image of the outside world.
The higher the number of ommatidia, the keener the vision becomes, with each unit contributing a different part of the complete picture. 35
The head of the common housefly is dominated by a pair of large compound eyes containing approximately 4,000 ommatidia. In wingless insects such as female fireflies there are 300 ommatidia, 5,100 in mayflies, 9,000 in yellow-winged coleopterans and between 10,000 and 28,000 in dragonflies and damselflies.
The wide visual perspective of a fly's eyes.
A Visual Range of 360 Degrees
The housefly's eye contains 4,000 small, simple ommatidia which can be moved at will. Since each ommatidium faces a different direction, the fly is able to see to the front, back, left, right, top and bottom, giving it a 360 degree perspective of the world.
Each ommatidium is sensitive to light shining in its direction, and uses its own lens and eight sensitive cells to process it. House flies have a combined total of 48,000 light-sensitive cells, allowing them to see 100 images per second. In this regard, their vision is ten times superior to the human eye. Two-thirds of the fly's brain is devoted purely to sight. The total number of light-sensitive cells means that 48,000 signals are sent here every tenth of a second.
Most people think of the fly as one of the most basic forms of life, but its visual system is in fact one of the most complicated we know.
Thanks to the flawless design of its eyes, the housefly can look 360 degrees around. At left, a detailed diagram of an ommatidium, of which the fly's eye contains some 4,000.
A tiny fly did not evolve or mutate its 4,000 eyes over a period a time. Clearly. This is a special creation. Of course, the fly is not composed of merely its visual system-it also has special digestive, reproductive and flight systems. Only with all its systems intact can the fly thrive. It is not possible for a fly to exist, for example, without a digestive or respiratory system. Nor are there any blind insects flying around! This is solid evidence that the fly was created by God in its current state, as mentioned in the Qur'an:
Mankind! An example has been made, so listen to it carefully. Those whom you call upon besides God are not even able to create a single fly, even if they were to join together to do it. And if a fly steals something from them, they cannot get it back. How feeble are both the seeker and the sought! (Qur'an, 22: 73)
An Insect with 56,000 Eyes
Among all known species, dragonflies have the greatest number of ommatidia. Each eye contains 30,000 of them,36 which can clearly see objects up to 20 feet away.37
To recap this phenomenon, a single tiny insect has a total of 56,000 eyes, each of which has a lens, retina, and thousands of nerves connecting it to the central nervous system. As a result of this, the dragonfly can see its prey and understand what it is seeing.
The presence of just a single eye with a single neuron and the ability to evaluate a single signal is a miracle on its own. But there are thousands of these eyes, all working in complete harmony. This is just another of God's countless phenomenon. God is the One Who has no equal in creation.
Ultraviolet Vision
Butterflies and bees both possess a special sense of sight, allowing them to reach sources of food with ease.
In some flowers, the pigments form distinct patterns that are invisible to us, but visible to bees and butterflies, who can see ultraviolet light. Called nectar guides, these patterns are like the landing strips of an airport, directing the insects to the nectar within the flower. It is as if their food sources were lit up and signposted especially for them. To our eyes, the coneflower appears to be a uniformly yellowish orange, but to a bee or butterfly, it appears as a corona of yellow with a glowing ultraviolet bull's eye in its center. This pattern guides the bee to where it can collect the nectar or pollen.
Bees feed on the pollen produced by plants. The plants, on the other hand, needs the bee to spread their pollen among other flowers of the same species in order to reproduce. Therefore, the flower uses its petals to attract the bee and sticks pollen onto the bee's legs as it feeds. Both partners possess the necessary features to enable this collaboration. Imagine a situation wherein flowers continued to reflect in the ultraviolet range, but bees were unable to see that portion of the spectrum. Both species would swiftly go extinct, because the bee would not be able to feed, nor the flower to reproduce. This is proof that these co-dependent organisms were created by the same Creator.
Birds
For a flying creature, the most important sense is sight, because the miracle of flight would become a very dangerous affair without the
ability to see. Birds, therefore, have been blessed by God with a superior sense of sight, in addition to the ability to fly.
A bird's sense of sight has a wider perspective and can operate much more quickly than a human's can. An object or view that we humans have to regard at length, a bird can see as a whole, in one quick glance.
Eyes are crucial for the predator owl, which can see ten times more powerfully than humans at night.38
Unlike a human, a bird cannot move its eyes in their sockets. But birds can quickly move their heads and necks around to expand their perspective. Without moving its head, an owl has an 80-degree field of vision. But some species of owl can rotate their heads to up to 360 degrees-a full circle!
The visual field of one human eye is 150 degrees laterally, and only 180 degrees binocularly, or a half circle.39
As mentioned already, predators such as the owl have very keen night vision, often six times greater than that of humans. This allows them to perform precisely accurate hunting maneuvers.
Larger eyes contain more visual cells, providing better vision. A predator bird can have more than a million visual cells in each of its eyes.
At night, owls and similar nocturnal birds can see much better than other species. Looking for food, these predator birds search for small animals on the ground, and their eyes can pick up the slightest movements, thanks to a high number of light-sensitive rods in their retinas. As we explained, the more rod cells, the keener night vision becomes. But for this vision, predator birds do pay a price: They sacrifice the sense of color. They see the world in black and white but, owing to their lifestyle, they do not need to see color. So cone cells are quite fewer in the eyes of nocturnal birds.
During the past minute, as you read this book, you blinked 22 times. That's how your eyes maintained their moisture and cleanliness. But for that split-second that you blinked, your eyes stopped doing their job. For the relatively sedate lifestyle of a human, this may not be a problem. But for a bird in flight, that split-second may be critical.
This is why birds have a third eyelid-a transparent layer that blinks and cleans-without their having to close their outer eyelids. This lid sweeps sideways across the eyeball, starting from the side nearest the beak. For birds that dive underwater, it also acts as goggles, protecting the eye from harm. In a sense, birds have been equipped with goggles and aviator glasses from birth.
Although nocturnal birds cannot see color, some smaller birds feed on seeds and insects, and therefore do need to discern colors. The eyes of these smaller birds are placed on either side of the head, which lets them see a wide area with minimal movement of the head and neck.
The umbrella birds, also known as black herons, encounter a number of difficulties when they hunt in water. As is well-known, most light reflects off the water-which has a negative effect on the bird's ability to see objects under the water's surface. The black heron solves this problem by spreading its wings. This cuts the sunlight and any reflections, allowing it to see more clearly and hunt for fish underwater.
If the black heron didn't use its wings this way, it would be unable to see its food and therefore starve. But seabirds are somehow born knowing the laws of optics, and take the needed precautions accordingly. Could it be that all the seabirds came together to find a practical solution to their problem? Or did they take a mass physics lesson and arrive at a solution by experimenting?
Hunting Eyes
Eagles fly at an altitude of thousands of meters, in a manner similar to modern war planes, yet are able to comb the landscape below in staggering detail. The eagle can detect even the slightest of movements or color changes while in flight. It owes this ability to a very special eye structure.
In humans, the portion of the retina with the most acute vision is the fovea centralis, which has the highest concentration of cone cells. Eagles have two foveae, giving them an incredibly sharp sense of sight. Humans have only one fovea in each eye-for binocular, or forward vision. When we look at an object, both our eyes are directed toward the object. This allows our brain to merge both the images to create a sense of depth. The eagle contains a binocular fovea like ours, but also has a fovea for monocular vision that allows each eye to look sideways and see a separate image. So eagles can see both forward and to the side at the same time.40
The eagle has a visual perspective of some 300 degrees, as well as an extra focusing power. Humans change the shape of their lenses to focus. But an eagle can change the shape of both lens and cornea. This gives it extra focusing power.41 It can also scan a 30,000 hectare (116 square miles) field from an altitude of 4,500 meters (14,700 feet), or spot a camouflaged rabbit from 90 meters (300 feet) with ease.42
To attain this super-sharp vision, an eagle's retinal cells are tinted with special colored oil droplets, increasing the contrast for objects seen against the blue sky or green forest. Thanks to this, the eagle can spot minute changes in contrast from thousands of meters above and swoop down to hunt. The fact that a mere drop of oil makes this possible is doubtlessly one of God's countless blessings.
Flying is a miracle in itself. If one aspect of the present structure or position of a bird's wing were changed, it would be unable to fly. Therefore, it isn't possible for wings to have evolved over time.
As mentioned before, something else that couldn't possibly have evolved is the visual system. This is reinforced by the flawless nature of an eagle's eye. An eye with two foveae cannot form over time, as a result of coincidences. That second fovea was deliberately created to answer the bird's needs.
For an eagle, that droplet of oil in its retina cells is of staggering importance... But who made this fine optical adjustment? Did the eagle add
the oil himself, or on other animals' recommendation? Of course not. The eagles have enjoyed this feature from birth, for thousands of years.
So why are our eyes not as sharp as an eagle's? If human eyes contained the same features, they'd each be the size of a grapefruit. Moreover, humans don't need to spot a camouflaged rabbit from a kilometer away. This is why God gave humans their present eyes in a most aesthetic form.
Jumping Spiders
Compared to ordinary spiders, the jumping spider leads a very unusual life. Rather than make a web and wait for a catch, these spiders hunt their prey instead. This is why-unlike ordinary spiders, which are almost blind-they have exceptionally acute vision.
A jumping spider hunts by securing itself to the branch of a tree with the thread it secretes. Then it throws itself toward an insect flying nearby, catching it in midair. In order to snare its catch, the spider needs to see its prey, and determine the direction and speed at which the target is traveling. Also, of course, it must determine its own speed and the duration of the leap. In order to do all this, the spider needs not only an advanced visual system, but an information processing center to make all the necessary calculations.
Jumping spiders have four pairs of eyes, for a total of eight. The front two are the most impressive, perhaps the best eyes one can find in any arthropod. The retina inside the eye can move in three dimensions, enabling the spider to look in all directions and focus on its subject. The other six eyes are positioned around the head, affording 360-degree vision.43
The jumping spider's visual acuity is actually very similar to our own, such that they even perceive images on a television screen. When most animals look at a television, they see only a series of moving dots. But research has indicated that jumping spiders respond to televised pictures of other spiders and insects.
The jumping spider's visual system is highly complex and, in some respects, surpasses even a human's. A tiny spider can look in different directions, detect motions, and estimate speed and distance. Of course, the spider never asked for these abilities, nor did it develop them on its own, over time. Everything the spider possesses was given to him by God.
The Protection of Animal Eyes
As the body's most sensitive organs, the eyes must therefore be well protected. This is why animal skulls have been constructed in such a way as to provide their eyes with maximum protection.
In animals like cats and dogs, the majority of the eye lies inside the skull, with only a small portion protruding outside. The bones surrounding the eye effectively act as a shield against impacts, and the eyelids help protect against direct injury.
The eyes of a camel-a mammal that lives under incredibly harsh conditions-are provided with the protection they need. The bone structure around its eye not only protects it from impacts, but also from harsh sunrays. Not even violent sandstorms can harm a camel's eyes, thanks to its eyelashes, which are long and intertwined, preventing any dust from entering.
Eyes in the Sea
There are considerable differences between land and underwater creatures, because under the surface is effectively another world, whose inhabitants have been modeled to best suit their environment. But just because they spend their lives underwater doesn't mean that their basic requirements are any different from ours. To stay alive, they still need to breathe, feed and avoid being hunted. They have to be able to see the world around them, so that they can distinguish between prey and foe-and require special eyes that let them see clearly underwater.
Fish view their world through a transparent layer that covers their eyes, similar in principle to the goggles worn by human divers. But be it a whale or a herring, an underwater creature's field of vision is restricted. Deeper than 30 meters (99 feet) below the surface, distant vision becomes unnecessary. Most of the time, in fact, fish need to see only those objects directly in front of them, and their eyes are created to meet this need. Their rigid, globular lens is particularly adapted for seeing close objects. But when they do need to see at a distance, a set of special muscles pulls the entire lens back toward the retina.44
The spherical lens in a fish's eye works well underwater. Because of the higher degree of refraction (the bending of light) in water than in air, a fish's lens has to be much more curved than a human's. To produce a clear image, the lens bends the light a lot more than does a flatter one-such as those in humans and other land animals.45
Water creatures are always in danger of becoming food for larger creatures. But they do have a special defense mechanism not seen in mammals: Fish can perceive more than one image at the same time.
A fish's eyes are placed on either side of its head. The image seen by each eye is recorded in the opposite half of its brain. But since the image is viewed by one eye only, it is two-dimensional, which prevents the fish from judging distances. This is why, when it spots some potential threat, both eyes focus in the same direction to judge the distance. Straight ahead, the visual arcs of the two eyes overlap to provide a narrow band, where the fish enjoys binocular vision.
With the exception of a few species, fish cannot see in color. They have no need to, because only a few meters underwater, most colors are absorbed and disappear. A fish's entire world is mostly shades of blue and green.
Fish are more sensitive than land animals to dim light, because their retinas contain a higher number of cells sensitive to low intensities, letting them make use of every amount of light possible.
Sea turtles generally feed on fish. In the process, they also consume a large quantity of sea salt, which could be unhealthy if they digested it. Rather then simply eject salt from the body, the turtle transfers it to special sacs located on to the side of its eyes. Here, the salt is cleverly recycled and used to produce tears.46
Octopus Eyes
Of all the invertebrates, the octopus has one of the most complex eye structures. As in vertebrates, each of the octopus's two large, complex eyes is like a camera, in structure, and the creature's vision is acute.
The octopus eye and the vertebrate eye are extraordinarily similar. Each includes a cornea, an iris, an accommodating lens, a fluid-filled vitreous humor, and a retina. However, there are major differences. For instance, octopi change their range of focus by moving the entire lens closer or farther away from the retina, whereas we change the shape of our cellular lens in order to bring objects into focus.
As mentioned earlier, one of the biggest struggles for evolutionists was in forming some explanation of how octopus eyes originated. According to evolutionary theory, octopi (which are invertebrates) and men (vertebrates) developed completely independently of each other, over time. And yet both man and octopus have equally well-developed visual systems, with similar structures performing similar functions.
But if the two species developed separately, why are their eyes so similar? It seems that the impossible has taken place not just once, but at several times and in several places. If the human eye is the product of coincidences and not creation, then shouldn't it be considerably different than the octopus's eye? The theory of evolution simply cannot answer thousands of basic questions like this.
The Archer Fish
Archer fish hunt by firing mouthfuls of water at nearby insects. Their superior sense of sight allows them to make acute geometric calculations from underwater so as to estimate the correct location of the prey in the outside air. They never miss their targets. This intelligent behavior surely is not the work of the fish itself. It is God Who inspires the Archer fish and all other creatures how to act.
This fish is famous for being a living water pistol-filling its mouth with water and squirting it at insects resting on branches or twigs above the water. The element of surprise causes the insect to lose its grip and plunge into the water, where it becomes an easy catch.
What's remarkable about the process is that even as the archer fish prepares itself, it doesn't raise its head out of the water. While still submerged, it can accurately determine the insect's location. But the apparent position of objects outside the water is distorted by the retraction of light. For example, if you wanted to shoot an arrow from beneath a swimming pool at a point in the air outside, you'd have to know at what angle light retracts upon the water and adjust your aim accordingly.
But this fish seems to overcome this problem and shoots on target every time. It is able to hit a tiny insect with no difficulty.47 All archer fish possess this ability, but not through lessons and physical calculations. It is God Who inspires this creature.
The Crab's Periscope
A crab has two eyes on the ends of stalks. These act like little periscopes, allowing the crab to see what's going on above, even if it is hiding beneath the sand. At any sign of danger, the stalks can be lowered for protection into sockets on the carapace.
REPTILE EYES
Most reptiles can see a large array of colors, allowing them to pick out even the most effectively camouflaged insects. This gives them a major hunting advantage.
Chameleons feed on insects, and their hunting tactics are most unusual because their eyes play a greater role than usual. Chameleons can move each eye independently of the other, allowing them scout the surroundings and watch their insect prey at the same time, as they edge closer to their objective.48 When it is close enough, a chameleon turns both eyes upon its prey, determines its position, and then shoots out its long sticky tongue to catch the meal.
Double Vision
On most species of snakes, the eyes are placed on either side of the head, which produces two different images in the snake's brain.
However, this location of the eyes doesn't stop the snake from seeing forward. In fact, this positioning gives the snake a wide visual perspective, allowing it to look forwards, backwards and upwards with ease.
Infrared Vision
As you've seen, the human eye can perceive only a specific range of wavelengths of light. Some species of snake are capable of seeing greater wavelengths than humans, including infrared light, which humans can sense only as heat.
Snakes have small pit organs that can visually register infrared radiation. These organs are a hundred thousand times more sensitive to infrared than human skin and can detect even the slightest change in a body's temperature.
For example, the rattlesnake can locate a warm-blooded animal or human even in pitch darkness, because such creatures radiate off heat waves that the snake can detect-an incredible advantage for any creature hunting at night.
The principle of detecting objects and soldiers by the heat they emit is also used in recent optical military equipment. It took years of research to develop the technology behind this kind of equipment, but snakes enjoy the same ability from the moment they hatch from their eggs. It took decades for humans to develop heat-sensing equipment, but snakes have always had it.
Eyelids
There are vast differences between a reptile's eyelids and the eyelids of other creatures. It may appear as if snakes do not have eyelids, for example, but their eyes are in fact covered by an immobile, transparent layer of scales.
Lizards, on the other hand, have movable eyelids. But in the desert lizard especially, the eyelids are upturned. This keeps out the sand, preventing it from harming the eye when the lizard buries itself in the sand.
The Sensitive Eyes of a Frog
Recent research has revealed some of the frog's eye's interesting abilities. One kind of retinal cell responds strongly to small, dark, round moving objects and is most active when those objects moved irregularly. It is as if the neurons of the frog eyes were designed especially to detect flies. Some scientists call their eyes "bug detectors."49
Cats' Eyes
The eye of a cat contains a layer called the tapetum lucidum, not found in humans. Positioned immediately behind the retina, it reflects incoming light, doubling the amount of light the eye can use and allowing cats to see in much dimmer light than we can.
This layer is also the reason why cat eyes seem to glow when a flashlight beam is shined directly at them.
Cat eyelids are prized wide open at night, allowing as much light as possible to enter. Another reason why cats can see so well in the dark is because their retinas contain more rod cells than cone cells. Thanks to this system created by God, wild cats can comfortably hunt at night.

Color-enhanced image taken by a scanning electron microscope of retinal pigment epithelial (RPE) cells derived from human embryonic stem cells. The cells are remarkably similar to normal RPE cells, having a hexagonal shape and growing in a single, well defined layer. These cells are the ones responsible for macular degeneration, the most common cause of blindness. CIRM scientists hope to one day treat macular degeneration with transplanted RPE cells derived from human embryonic stem cells.
The image was taken in the lab of David Hinton at the University of Southern California.

Taken with my Panasonic Lumix DMC-FZ35.
A large infestation of milkweed tussock moth caterpillars decimated this one milkweed plant.
In just a couple days the group of hundreds had eaten every single leaf so that only the bare stalk and branches of the large plant were left.
Here is a small group out on the edge of one of the barren branches.
It can be extremely difficult enough to get perfect 3D images of just single insects in the frame without having any retinal rivalries using the cha-cha method when taking 3D photos, but when there are a couple or large groups of insects . . . YIKES!!!
A retinal rivalry can occur when one image may have a subtle or drastic difference in one or more areas between the two images, so that while viewing the pair of images in 3D, the affected area looks distorted or incorrect, which can lead to eye strain discomfort or an uneasiness while viewing the image in 3D.
In case some people are wondering what the cha-cha method is, it's the process of taking 2 separate photos of the same subject(s), but at 2 slightly offset angles along a horizontal plane. You snap 1 photo, then move the camera either slightly left, or slightly right horizontally, then snap a 2nd photo.
You can then place these 2 slightly offset images side-by-side to create a stereo 3D image. Or, you can overlap the 2 images, but remove the red color channel from one image, while removing the green and blue color channels from the 2nd image. This is called an anaglyph image and requires those funny looking glasses with the red and cyan colored lenses in them so that you can see the overlapping images as a single 3D picture.
However, while using the cha-cha method, movement of the subjects or anything within the surrounding background area between the taking of one image to the second will cause these rivalries in the final 3D image.
So one trick that I have used often with certain insects to avoid or at least extremely limit the possibility of rivalries, is to slightly breathe out on them. The instinctive defensive action of many insects to avoid predators looking to eat them, is to stop moving in an attempt to blend in to their surroundings.
So with a gentle breathe some insects seem to associate that with the presence of a possible predator, and immediately stop all their movement. Another trick is to just cause a mild vibration near some insects, or actually gently touch them, and the same defensive reaction of staying perfectly still may also be employed.
This defensive freezing time can then be used to quickly get my 2 or more photo captures at the various horizontal positions I need to create my 3D images of the insects. Of course insects don't always cooperate, especially when there are groups of them within your photo framing, so it's always a hit or miss venture!
However, I have used these techniques very successfully many times on various insects . . . unfortunately the same techniques will certainly do the opposite and scare away many insects as well . . . you learn with experience which ones to annoy in this fashion, and which ones not to annoy! ;-)

The German Shorthaired Pointer is a breed of medium-sized pointing dog developed in nineteenth century Germany. It is energetic and powerful, with strong legs and great endurance. It is a versatile all-purpose gun dog suitable for hunting and retrieving on both land and water, with a strong drive to find and chase game. It may also be kept as a companion dog, though as a high-energy sporting dog, it requires significant amounts of exercise.
German Shorthaired Pointers have a short coat that comes in various combinations, generally a mix of liver and white. They have moderately long floppy ears set high on the head. Longer, broad, and strong, muzzles allow retrieval of heavier game. The dog's profile should be straight or strongly Roman nosed; any dished appearance to the profile is incorrect according to breed standards. Their eyes are generally brown, with darker ones being desirable; yellow or "bird of prey" eyes are a fault. The tail is commonly docked, although that is now prohibited in some countries. In competition, they are penalized if the tail is curved either up or down while the dog is moving. When the GSP is in classic point stance, the tail should be held straight out from the body, forming a line with the pointing head and body. Like all German pointers, GSPs have webbed feet, and are known for going after waterfowl in the water.
The German Shorthaired Pointer is a member of the Sporting Group. In 2016, CJ, a three-year-old German Shorthaired Pointer, won the Best in Show award at the 140th Westminster Kennel Club Dog Show.
Appearance
The German Shorthaired Pointer's coat is short and flat with a dense undercoat protected by stiff guard hairs, making the coat water resistant and allowing the dog to stay warm in cold weather. That allows the dog to be an agile hunter, with high performance in both field and water. The coat can be a dark brown with some lighter brown colors, referred to as "liver" (incorrectly as "chocolate" or "chestnut"), black (although any area of black is cause for disqualification in American Kennel Club-sanctioned shows), white, liver roan, or liver and white.
Health
Most German Shorthaired Pointers are tough, healthy dogs, but the breed can be subject to a number of hereditary disorders due to their breeding. Some of these health disorders include, hypothyroidism, hip dysplasia, osteochondrosis dissecans (OCD), pannus, progressive retinal atrophy (PRA), epilepsy, skin disorders and cancerous lesions in the mouth, on the skin and other areas of the body. As with other breeds, un-spayed female GSPs are prone to breast cancer. This risk is reduced if they are spayed.
A genetic form of lupus, termed exfoliative cutaneous lupus erythematosus (ECLE) has also been recognized in German shorthaired pointer dogs.
Care
The GSP has a median lifespan of 9 years in a Danish survey and 12 years in a UK survey. In the UK survey about 1 in 8 lived to >15 years with the longest lived dog living to 17 years.
History
German hunters spent generations crossing different breeds until the GSP came during the 1800s. They were successful to the point that the GSP is among the top-winning breeds in competitive hunting events. According to the American Kennel Club, it is likely that the GSP is descended from a breed known as the German Bird Dog, which itself is related to the Old Spanish Pointer, introduced to Germany in the 17th century. It is also likely that various German hound and tracking dogs, as well as the English Pointer and the Arkwright Pointer also contributed to the development of the breed. However, as the first studbook was not created until 1870, it is impossible to identify all of the dogs that went into creating this breed. The breed was officially recognized by the American Kennel Club in 1930. World War II affected the breeding of GSP. Toward the end of the war many of the breeders hid their gold, diamonds, their GSPs and more. Then the best dogs were sent to Yugoslavia for safe keeping. Today the GSP ranks 19th among the 155 breeds and it varieties recognized by the AKC.
Current uses
Like the other German pointers (the German Wirehaired Pointer and the less well-known German Longhaired Pointer), the GSP can perform virtually all gun dog roles. It is a pointer and retriever, an upland bird dog, and water dog. The GSP can be used for hunting larger and more dangerous game. It is an excellent swimmer but also works well in rough terrain. It is tenacious, tireless, hardy, and reliable. German Shorthaired Pointers are proficient with many different types of game and sport, including trailing, retrieving, and pointing pheasant, quail, grouse, waterfowl, raccoons, opossum, and even deer.

German Shorthaired Pointers are still currently used as versatile hunting and gun dogs. With their high intelligence and athleticism the German Shorthaired Pointer performs well in many AKC sports such as Agility, Dock Diving, and Obedience. German Shorthaired Pointers are also used in law enforcement for nosework such as the detection of illicit substances.

Professor Ted Maddess from The John Curtin School of Medical Research studies a range of eye diseases. He and his group have invented a machine that accurately maps the visual field of the retina, and also tests the nerve connections between the eye and brain.
Could this invention help diabetes patients? The two researchers got together to find out.
They are exploring whether Professor Maddess’s invention can do these jobs: early detection of diabetes for people at risk, and effective management of the disease by closely tracking its effects.
The technology can find two complications of diabetes related to eyesight: retinal neuropathy, or damage to the retina (which is a neural tissue, an outgrowth of the brain); and retinopathy, where abnormal blood vessels of the retina cause a loss of vision.
Retinal neuropathy seems to precede retinopathy, and finding it could inform treatment decisions and patient behaviours – to prevent more serious damage.*
This test may not only help diabetes patients by preserving eyesight through early detection and treatment, but also by serving as an indicator to whether a patient’s individual treatment is preventing damage to the rest of their body. Other diabetes complications include cardiovascular disease – which kills over 60 per cent of people with type 1 diabetes, kidney failure, foot ulcers and lower limb amputations.
The collaboration between this vision researcher and diabetes clinician became even more exciting when the project was folded into the winning Grand Challenges Scheme, Your Health in Your Hands: Future Personalised Medical Technologies for a Sustainable and Effective Healthcare.
This project seeks to deliver better care for chronic diseases, regardless of a person’s location or access to a major hospital.
The first aspect is early detection of chronic diseases, followed by better management of a disease through precision therapies. With further innovation in miniaturised or wearable sensors, patients in any location would be able to record timely information about their health as they undergo daily activities. Both the cost and outcomes of disease management could improve by less episodic intervention, and by targeting treatments to an individual’s specific condition.
Your Health in Your Hands will focus first on two chronic diseases: diabetes and multiple sclerosis (MS).
Diabetes alone affects seven per cent of Australia’s adult population (rising to 14 per cent among indigenous adults). Its death rate is twice as high in rural areas where detection and management services are less available. The disease is underdiagnosed; a quarter of sufferers are diagnosed only after the disease presents serious health consequences.
The project brings together innovations from several corners of the University. These include:
Genomics, to figure out which patients are at risk and help devise effective, personalized therapies
Engineering, to create tools that measure key aspects of an individual’s health
Public health experts, to improve the patient experience and ensure delivery across the population; and
Big data, to process the avalanche of data to discover how genetics, symptoms and diseases are related, and to find which therapies work best for which patient.
The team involves 52 researchers at ANU, across six Colleges. The University’s depth and breadth provide a unique environment for the success of this wide-reaching effort.
Eye health for diabetes sufferers is just one piece of the puzzle.
“You need to ask a bunch of independent questions. Medical knowledge is multidimensional. Maybe we measure 10 things about each patient – if they all tell you the same thing, you might as well have asked the same question 10 times” explains Professor Ted Maddess. “You want to have multiple tests that each give you different information.”
This way you can find out what makes one diabetes patient (or MS patient) different from another, and which treatments will be most effective for that individual person.
When experts from different fields get together, possibilities expand.
Professor Maddess described a meeting of the Grand Challenges team where Professor Nolan posed a question.
“Chris was saying ‘This is what diabetes is. It would be great if we could measure this.’ And then the chemist and the engineer in the room said, ‘I measure that!’”
*Almost all patients with type 1 diabetes, and 60% of those with type 2 diabetes, currently develop vision-threatening eye damage within 20 years of diagnosis.
