A pinwheel in many colors
(Phys.org) -- This image of the Pinwheel Galaxy, or also known as M101, combines data in the infrared, visible, ultraviolet and X-rays from four of NASA's space-based telescopes. This multi-spectral view shows that both young and old stars are evenly distributed along M101's tightly-wound spiral arms. Such composite images allow astronomers to see how features in one part of the spectrum match up with those seen in other parts. It is like seeing with a regular camera, an ultraviolet camera, night-vision goggles and X-ray vision, all at the same time. -

14:24One of the greatest cliches uttered about her majesty Queen Elizabeth II is that in 60 years of reigning over us, "she has never put a foot wrong". This may well be true, but how do we know? What do we really know about how the Queen fulfils her constitutional functions? Does she intervene in the political affairs of the countries over which she reigns? Does she exercise substantial political power? Or is she just a rubber stamp - a form of eccentric British formality that has charm but no substance?

14:24(Phys.org) -- An international collaboration of scientists, including Thomas Blum, associate professor of physics, is reporting in landmark detail the decay process of a subatomic particle called a kaon – information that may help answer fundamental questions about how the universe began.

14:24Namibiaʼs NamibRand Nature Reserve, one of Africaʼs largest private nature reserves, has expanded its conservation role to include preserving the star-filled nighttime skies that shine above its dunes and mountains. These efforts in night sky conservation have earned the reserve high honors as the International Dark-Sky Association has just announced that NamibRand Nature Reserve is the worldʼs newest International Dark Sky Reserve.

14:24(Phys.org) -- If you look at a razor burrowing clam sitting in a bucket, you’d never guess that it could burrow itself down into the soil, much less do it with any speed. Razor clams look like fat straws, or sawed off tusks; not very exciting. But set one down in the water, and it can burrow down into the sand to about two and a half feet deep in just a couple of minutes. Pretty impressive stuff, especially considering, as a team of researchers has found, that the muscle the clams use for burrowing just isn’t strong enough to accomplish the deed. To manage the speedy descent the team found, the razor burrowing clam causes changes to the sand below it as it descends. They have written a paper on their findings which has been published in the Journal of Experimental Biology.

14:24A research team from the University of Tokyo/Kavli IPMU, Ehime University, and the National Astronomical Observatory of Japan (NAOJ) has succeeded in conducting the first, full-scale scientific observationswith an adaptive optics (AO) system at optical wavelengths. The team connected the Kyoto Tridimensional Spectrograph II with the Subaru Telescope's Adaptive Optics system and improved the spatial resolution of images by a factor of 2.5 over images taken without AO. Observations using Kyoto3DII coupled with AO 188 are likely to reveal the detailed structures and the formation processes of galaxies.

12:24(Phys.org) -- OmniVision has announced two high-resolution image sensors for the digital still and digital video camera market (DS/DVC) and higher end smartphones. In end-user language, it is a claim for superior quality visuals for digital video cameras and top of the line mobile phones. The company sees its marketplace comfortably split between those end users who hold on to their cameras and those who turn to smartphones for neat imaging features. The newly announced high-resolution mobile sensors can capture 4K2K video. The 16-megapixel camera sensors are part-number dubbed the OV16820 and OV16825.

12:24(Phys.org) -- The unilateral efforts of a single country or region to reduce the emissions of greenhouse gases could reduce exports, increase imports and lead to higher emissions elsewhere – what economists call “leakage.” Unilateral efforts could, however, work better if other sources of energy were used as substitutes, thereby creating “negative leakage,” according to research by University of Illinois energy policy experts.
