A first true attempt at very close-up macro using a point and shoot camera combined with a 10x microscope eyepiece; As I wanted to do focus stacking, but the flower moved as the camera did, as the camera was pushing up against the flower, as the focusing distance was so close. I hope to get a lens with a far greater working distance and that can have less magnification, down to 1X.
Profession gardien de Zoo à mi-temps, il faut assurer le repas bi-hebdomadaire des tardigrades de l’expérience Cell Science 4 🔬. Les chercheurs étudient les effets de l’impesanteur et de l’environnement spatial sur ces créatures microscopiques qu’on surnomme parfois oursons d'eau. L’espèce la plus grande peut mesurer jusqu’à 1 mm de long, mais en général ils sont microscopiques… Ces créatures sont incroyablement résistantes, capables de survivre à des environnements extrêmes sur Terre comme dans l’espace : certains sont revenus de plusieurs jours à l’extérieur, dans le vide, avec des températures de +100 à -100 degrés, sans un dommage... Dans le cas de Cell Science 4, les scientifiques essayent d’identifier les gènes qui leur permettent de survivre durant des séjours plus ou moins longs dans l’espace, et d’évaluer comment l’utilisation de ces gènes change au cours des générations dans le but d’exploiter pour les humains les secrets de leur incroyable résilience !
Feeding the tardigrades! 🌱 Researchers are investigating the effects of microgravity on these microscopic creatures, also known as water bears, through an experiment called Cell Science 4🔬 #DYK the largest tardigrade species is just over 1mm in length and they're incredibly hardy – surviving extreme environments in space and on Earth. In this case, researchers want to characterise the genes that allow tardigrades to survive during short and long periods in space, then assess how the use of these genes changes across generations Maybe we can harness their secrets!

A fluorescent microscopic view of cells from a type of bone cancer, being studied for a future trip to deep space – aiming to sharpen our understanding of the hazardous radiation prevailing out there.
Today’s astronauts orbiting close to Earth are protected from most space radiation by our planet’s atmosphere and magnetic field.
In future, astronaut missions are planned to Mars and beyond. But heading farther out to space would increase crews’ radiation exposure, not just from the charged particles expelled by our own Sun but also the heavy ions thrown out by the rest of the cosmos, known as ‘galactic cosmic radiation’.
Concern is greatest around the 1% of cosmic radiation nuclei the size of an iron atom or more – known as ‘high-ionising high-energy particles’ or HZE for short.
Accelerated close to light speed by magnetic fields as they cross the Universe, HZEs can slice right through DNA. The most serious class of damage is termed ‘double-strand breaks’, leading to loss of genetic information and potentially triggering cancer
“However cells do have an ability to repair double-strand breaks, and this is what we want to study,” explains Yassen Abbas, a young graduate trainee at ESA’s Life, Physical Science and Life Support Laboratory.
“The aim is to follow the repair process in real time; the cells we are using have a marker which will express a dedicated fluorescent fusion protein, allowing us to monitor the formation of DNA repair.”
The test subjects are osteosarcoma cells – a type of bone cancer – that have been selected because of their rapid growth characteristics. “The more cells per sample, the higher the chance of observing a radiation event,” adds Yassen.
The proposed experiment would include a camera to trace the progress of the repair process, returning images to the ground in real time.
But this isn’t an experiment that can be done on the International Space Station, or anywhere else in low-Earth orbit. Instead the proposed payload will have to be placed in deep space, while also keeping the cell samples alive and comfortable.
Yassen has been working on the practicalities of achieving this on a fully automated basis.
He adds: “At one time we were planning to fly as a passenger on ESA’s now-cancelled Lunar Lander. As an alternative, missions to other deep-space destinations could be considered, or else a dedicated CubeSat.”
The image has been fluorescently stained to visualise the cells’ nuclei in blue and their surrounding cytoskeleton in red. The image covers a length of approximately 305 micrometres (equivalent to 0.305 millimetres) The scale bar measures 25 micrometres across.

Photo taken with digital microscope of rock that I found along the South Yamhill River in Oregon. When I examine it with a low, diffused light and move the angle and direction of the light, many different surreal scenes and colors emerge and disappear.
There will be more to come of this rock.

The tomato we cut up for lunch had a black spot in it. Naturally, it went under the microscope.

Microscopic world of mushrooms (Dibaeis arcuata species) and green mosses. Due to cold weather at late autumn, these mushrooms are curling up then dry up (as seen at upper right, they turn reddish then dark).
This is a small section of the trailing edge of a mosquito’s wing at about x400 time’s magnification. An amazing array of scales protrude from the edges of the wing all the way round. These are layered in a way that must assist with flight. The veins in the wing also have two different types of scale - one type visible on the upper surface and another type on the lower wing surface. You can see the shadowed scales below the surface in this photograph. It is difficult even with multiple exposures combined, [photo stacking], to truly capture it all. Everything is so 3D at high magnification that only the tiniest slice of it is in focus at any one time. By the way - the little greenish flecks scattered over the image are I suspect hairs and other particles on the under side of the cover slip - hard to get everything right!
Looking at such delicate wing structures makes me think of the hymn "All things bright and beautiful'.
These tiny, unappreciated flowers measure 7mm in diameter. They pass almost unnoticed until you use a macro lens on them.
Taken with D7100 with PN-11 and extension tubes and a 105mm macro with a reversed 50mm lens and diffused flash. Handheld (chased hime around a lily leaf :-) )
