Almost to the nectar in the last few blooms from our George Davidson Crocosmia! A female Rufous Hummingbird is hoping to avoid detection from the other Hummingbirds in our yard to enjoy the Crosmia flowers.
If you look closely you can see some fine wires running from the tips of the tail planes to the mid-rear fuselage on each side. These were an early form of 'friend or foe' detection; a radio signal from them helped differentiate defending RAF aircraft from others on the crude radar screens of the time.
This aircraft has a 'c' type wing, sometimes called the 'universal' wing which had provision for up to four 20mm cannon and four 0.303 Browning machine guns, although because of weight restrictions, not all could be carried at the same time without seriously degrading the aircraft performance. It is not uncommon to see two of the cannons capped off, as here. The red tape over the machine gun ports was to prevent debris from muddy airfields being blown back into the guns from the propeller while the engine was running on the ground. Wet mud could jam the guns. Of course, the first shots would go straight through the tape.
The outer machine guns were often considered to be not all that effective - the wings would vibrate when they were firing, so an ever widening cone of bullets would issue forth reducing the effectiveness on the target. The 'e' wing, which many later Spitfires sported, was a simplified 'c' wing, had the outer four machine guns bays deleted and could carry heavier machine guns and/or cannon in the four inner bays.
The Chandra image shows Mira A (right), a highly evolved red giant star, and Mira B (left), a white dwarf. To the right of the image is an artist's conception of the Mira star system. Mira A is losing gas rapidly from its upper atmosphere via a stellar wind. Mira B exerts a gravitational tug that creates a gaseous bridge between the two stars. Gas from the wind and bridge accumulates in an accretion disk around Mira B and collisions between rapidly moving particles in the disk produce X-rays.
The separation of the X-rays from the giant star and the white dwarf was made possible by the superb angular resolution of Chandra, and the relative proximity of the star system, at about 420 light years from Earth. The stars in Mira AB are about twice as far apart as Pluto is from the Sun.
The ability to distinguish between the interacting stars allowed a team of scientists to observe an X-ray outburst from Mira A. An ultraviolet image made by the Hubble Space Telescope was key to identifying the X-ray outburst with the red giant star.
Mira A (or simply, Mira) was named "The Wonderful" star in the seventeenth century because its brightness was observed to wax and wane over a period of about 330 days. In this advanced red giant phase of Mira A's life, its diameter has swollen to about 600 times that of the Sun and it is pulsating, due to increasingly energetic nuclear reactions in its core.
Mira A is now approaching the stage where its nuclear fuel supply will be exhausted, and it will collapse to become a white dwarf. In contrast, Mira B has already reached the white dwarf stage, and is about the size of the Earth, but about a quarter million times more massive.
Before this observation it was assumed that all the X-rays came from a hot disk surrounding Mira B, so the detection of an X-ray flare from the red giant star came as a surprise. This outburst was likely an indirect consequence of the internal turmoil in Mira A.
X-ray studies of the Mira star system may also provide better understanding of interactions between other binary star systems

There is more than meets the eye in this image! 👀
A team of international scientists has used NASA’s James Webb Space Telescope to detect a new carbon compound in space for the first time. Methyl cation (pronounced cat-eye-on) (CH3+), was detected in a young star system, with a protoplanetary disk, known as d203-506, which is located about 1,350 light-years away in the Orion Nebula.
Carbon compounds form the foundations of all known life, and as such are particularly interesting to scientists working to understand both how life developed on Earth, and how it could potentially develop elsewhere in our universe.

Cosmic smoke & telescope mirrors?
Webb found complex organic molecules similar to smoke or smog in a galaxy more than 12 billion light-years from Earth. This sets a new record for the most distant detection of these big, complicated molecules: bit.ly/43M4YEG
The distant galaxy in question lies behind a much closer foreground galaxy. The gravity of the foreground galaxy is so great that it distorts and magnifies the light of the galaxy behind it, making it easier to see.
In space, where there’s smoke, there are stars — usually. But this galaxy might change astronomers’ long-held belief: These “smoky molecules” were abundant in some areas with little star formation, or were scarce in some areas with active star birth.
Due to how far light from this galaxy had to travel, we’re seeing this galaxy as it was back when the universe was < 1.5 billion years old. The discovery suggests that complex chemistry began occurring in the universe much earlier than we thought.
This image: The galaxy observed by Webb shows an Einstein ring caused by a phenomenon known as lensing, which occurs when two galaxies are almost perfectly aligned from our perspective on Earth. The gravity from the galaxy in the foreground causes the light from the background galaxy to be distorted and magnified, like looking through the stem of a wine glass. Because they are magnified, lensing allows astronomers to study very distant galaxies in more detail than otherwise possible.

Image Description: This is an infographic with a navy blue background. At the top left it says, "What creates an Einstein Ring?" In the center is a diagram. At far left is a drawing of Webb, labeled James Webb Space Telescope. In the center is a foreground galaxy, shown in blue. On the right is a background galaxy, shown in red. Arrows run in a diamond shape from the red galaxy around the blue galaxy, and to Webb. The lines are labeled "Distorted light rays." At the bottom there is another arrow pointing to the right that says "Looking further into the past." which implies the galaxy shown in red is older and farther away than the foreground galaxy, which has warped its light. At far right is the inset Webb image of the Einstein ring. In this inset, on a black background, there are two notable objects. There is a foreground galaxy seen as a big bright blue dot at the center of the frame. It is surrounded by an orange ring meant to highlight the discovery of organic molecules in the galaxy whose light has been bent into a circle. Near the top left of the image, there is also a distant background galaxy represented as a tiny red dot.
These Webb images show a part of the Orion Nebula known as the Orion Bar. While observing the Orion Bar, Webb made the first detection ever of a crucial carbon molecule called methyl cation (pronounced cat-eye-on) in space. Carbon compounds are the foundation of life as we know it, and methyl cation (CH3+) plays an important role in forming more complex carbon-based molecules.
Within this region, Webb found methyl cation inside a planet-forming disk surrounding a young star system. The disk was bombarded with UV radiation from nearby young stars. While UV radiation is typically expected to destroy complex carbon molecules, the science team believes it may actually be the source of energy necessary for methyl cation — and with it, more complex carbon molecules — to form. Ultimately, understanding how UV radiation changes the chemistry of these disks could tell us more about the origins of life.

In this image: The Orion Bar is a region where energetic ultraviolet light from the Trapezium Cluster — located off the upper-left corner — interacts with dense molecular clouds. The energy of the stellar radiation is slowly eroding the Orion Bar, and this has a profound effect on the molecules and chemistry in the protoplanetary disks that have formed around newborn stars here.
The largest image, on the left, is from Webb’s NIRCam (Near-Infrared Camera) instrument. At upper right, the telescope is focused on a smaller area using Webb’s MIRI (Mid-Infrared Instrument). A total of eighteen filters across both the MIRI and NIRCam instruments were used in these images, covering a range of wavelengths from 1.4 microns in the near-infrared to 25.5 microns in the mid-infrared.
At the very center of the MIRI area is a young star system with a planet-forming disk named d203-506. The pullout at the bottom right displays a combined NIRCam and MIRI image of this young system. Its extended shape is due to pressure from the harsh ultraviolet radiation striking it. An international team of astronomers detected a new carbon molecule known as methyl cation for the first time in d203-506.
Image description: An image made of 3 panels. The largest, left panel shows Webb’s NIRCam image of the Orion Bar. Billowy, multi-hued clouds fill the field of view. On the left side, the clouds are various shades of blue with some translucent orange wisps throughout. On the right side, the clouds vary from bright orange-red to brown. A slanted inset box in the top right of Panel 1 corresponds to a second panel at upper right. Panel 2 shows the same region as the inset box, but as seen by Webb’s MIRI instrument. In contrast to the NIRCam view, the upper left region is colored mostly orange but also red and green, while the lower right region is mostly pink, with dark blue, sparse filaments. Finally, a tiny box in the center of Panel 2 corresponds to a third panel at lower right. Panel 3 shows a blown-up view of Panel 2’s tiny box. Combining MIRI and NIRCam data, it features a yellow and orange blob on a red background. The blob is a young star system with a planet-forming disk named d203-506.

TRAPPIST-1 b: We give it a one (M-dwarf) star review; it lacks atmosphere. ⭐
Webb measured the dayside temperature of rocky exoplanet TRAPPIST-1 b and found it to be about 450 degrees F (227 degrees C), suggesting it has no significant atmosphere. This marks the first detection of any form of light — in this case, heat energy — emitted by a rocky planet that’s as small and cool as those in our solar system.
As a refresher, TRAPPIST-1 b is the innermost of 7 rocky planets (found in 2017) orbiting the M dwarf star TRAPPIST-1. M dwarf stars are intriguing because they are 10 times as common and 2 times more likely to have rocky planets than stars like our Sun.
These new Webb results give us important clues about TRAPPIST-1 b’s 3 siblings in the habitable zone (whose conditions could support liquid water on their surfaces) as well as other M-dwarf systems. It's a key step to figuring out if planets around M-dwarf stars can sustain atmospheres needed to support life, with a promise of more science to come.

This image: This illustration shows what the hot rocky exoplanet TRAPPIST-1 b could look like based on this work. TRAPPIST-1 b, the innermost of seven known planets in the TRAPPIST-1 system, orbits its star at a distance of 0.011 AU, completing one circuit in just 1.51 Earth-days. TRAPPIST-1 b is slightly larger than Earth, but has around the same density, which indicates that it must have a rocky composition. Webb’s measurement of mid-infrared light given off by TRAPPIST-1 b suggests that the planet does not have any substantial atmosphere. The star, TRAPPIST-1, is an ultracool red dwarf (M dwarf) with a temperature of only 2,566 kelvins and a mass just 0.09 times the mass of the Sun.
This illustration is based on new data gathered by Webb’s Mid-Infrared Instrument (MIRI) as well as previous observations
from other ground- and space-based telescopes. Webb has not captured any images of the planet.

⚕️ 💊 Megan et l’expérience 🇺🇸 Genes in Space qui a notamment recours à la méthode… PCR ! Même méthode que pour la détection du coronavirus – sauf qu'on étudie l’ADN de cellules de foie pour mieux comprendre les changements d’expression des gènes dans l’espace.
Ici beaucoup de médicaments n’ont pas le même effet que sur Terre... Alors un étudiant américain a eu l’intuition que les enzymes du foie qui métabolisent la plupart de ces derniers y sont peut-être pour quelque chose, et c’est l’objet de cette expérience. Megan a aussi utilisé une technologie qui se sert de la fluorescence pour l’étude de l’expression des gènes qui contrôlent les enzymes en question. Un appareil adapté à nos conditions spatiales et qui pourrait être utilisé sur 🌍 dans les zones isolées. 💪
Megan working on the Boeing/miniPCR bio Genes in Space-8 experiment. Students can propose cells to examine their DNA and how they adapt to spaceflight. This time it is the liver, which I know from biology lessons is one of the only organs that can regenerate on its own, so I think this choice is bound to reveal interesting data. Thank you Megan as always for the colours you never fail to add to my social media posts. According to the fashion-guidelines of Shane, Mark, Aki and myself, there are only three colours for shirts: black, navy blue, and grey. Life here would for sure be less colourful without you…

Christie's Poirot departs from both the medical profiling method and Holmes to become more of a collector and archivist in the film script versions of the Christie stories. It is here that Poirot's dramatized analytic method comes squarely into the sights of my world, for the series producers have painstakingly added exquisite details to the tools of Poirot as if he were related to James Bond. Incidentally, this kit is so much better than an teenager's make-believe kit, and no harder to assemble for the real thing. I have added a camera which would fit the level of analysis of Poirot's work.
The calf leather attaché detection kit functions to extract, collect and analyze. For this it generously contains the following:
envelopes for collecting particles, test tubes with droppers for liquids, fingerprint powder, various cutting (scissors & knives), picking & retrieving (different sized tweezers & forceps) tools, magnifying glass, magnifying loupe, pencil, gloves, cleaning cloth and agent, a camera with aperture & shutter settings for infinity and macro, a developer in a separate casing the size of a cigarette case, two sets of film holders with 5 plates each, and a small matching calf leather bound notepad which is not really necessary actually as Poirot arranges his points of interest inside the little grey cells of his brain.
PS: the camera will be uploaded in the near future

As fire seasons have become longer and more devasting, firefighters have looked to wide variety of technologies to assist with detection and response. The Alert Wildfire detection camera project, which began over a decade ago, was developed in conjunction with the Bureau of Land Management (BLM) Oregon/Washington, BLM Idaho, BLM Nevada, and University of Nevada Reno - Nevada and University of Oregon’s Seismological Laboratories.
In 2004, the University of Nevada Reno developed a stand-alone microwave network to support the change from analog to digital seismic station sensors. The microwave system runs on an unlicensed broadband public safety band that is networked across the states. This system has evolved from just transmitting seismic data, to the current wildfire detection video data from stations and cameras located primarily on BLM-permitted lands.
The cameras and associated tools help firefighters and first responders:
•discover/locate/confirm fire ignition,
•quickly scale fire resources up or down appropriately,
•monitor fire behavior through containment,
•during firestorms, help evacuations through enhanced situational awareness,
•ensure contained fires are monitored appropriately through their demise, and
•view prescribed fires both during ignition and during monitoring stages.
The camera network is fed by a single point mountaintop camera via microwave to central hosting point at the University of Nevada Reno. The cameras are 1080 high definition/high speed with pan, tilt, and zoom capabilities. The cameras also provide a live feed of for designated users of six frames per second.
Cameras provide a remote feed to a web page that updates the pictures every 10 seconds. Over the last several years, this innovative technology has provided critical information for thousands of fires throughout the western U.S.
In Fiscal Year 2022, the Oregon/Washington Bureau of Land Management awarded the University of Oregon (UO) $718,346 to help aid in wildfire prevention by developing the most integrated, and interorganizational wildfire detection system in the United States.
Funding will provide continued statewide access to vital information of emergent wildfires and provide for the most efficient and effective emergency response, thereby ensuring the quality of lives of Oregonians and protecting our natural resources.
In 2022, the BLM helped lead the establishment of an Oregon Statewide Wildfire Detection Camera System with the goal of establishing collaborative governance to establish and implement a statewide wildfire detection camera strategy that addresses a long-term detection camera build-out between the multiple agencies while also addressing current and future detection camera technologies.
The ALERTWildfire program continues to grow, the ability to locate smoke at a very early stage will ultimately allow firefighters more time to assess the situation and mobilize appropriate resources. This unique use of technology will save taxpayers money as well as our forests, grasslands, property, and lives, while managing risk to our firefighters through an informed response.
