There’s a weird asteroid shaped like a bone whipping around our sun
Astronomers have got their closest look yet at an unusually shaped asteroid orbiting the sun in the asteroid belt between Jupiter and Mars......»»
Researchers use structured light on a chip in another photonics breakthrough
In everyday life we experience light in one of its simplest forms—optical rays or beams. However, light can exist in much more exotic forms. Thus, even beams can be shaped to take the form of spirals; so-called vortex beams, endowed with unusual pr.....»»
Astronomers want your help hunting for asteroids
Anyone can become an asteroid hunter thanks to a new program launched by astronomers at the University of Arizona Lunar and Planetary Laboratory. As part of the Catalina Sky Survey, the scientists created an online portal that opens their mission—t.....»»

Researchers discover an alternative to ATP for string-shaped motors in cells
Cells have a fascinating feature to neatly organize their interior by using tiny protein machines called molecular motors that generate directed movements. Most of them use a common type of fuel, a kind of chemical energy, called ATP to operate......»»
From enormous elephants to tiny shrews: How mammals shape and are shaped by Africa"s landscapes
Africa is the world's most diverse continent for large mammals such as antelopes, zebras and elephants. The heaviest of these large mammals top the scales at over one ton, and are referred to as megafauna. In fact, it's the only continent that has no.....»»
I used System76’s Pangolin for weeks, and Linux was not the biggest problem
A comfy keyboard, weird trackpad, blah webcam, and notably mature Linux desktop. Enlarge / The Pangolin has a somewhat plain, practical all-black look. It gets a little wilder when you start plugging things into its gracious arra.....»»
This weird profile trick brings back blue checks for Twitter accounts – but not for long
In the latest chapter of Twitter strangeness, it’s surfaced that a tiny tweak to the profile description of legacy verified accounts will bring back the blue checkmark. Here’s how it works and what to expect if you give it a shot. more… The p.....»»

Scientists design new bio-inspired molecules to promote bone regeneration
People's ability to regenerate bones declines with age and is further decreased by diseases such as osteoporosis. To help the aging population, researchers are looking for new therapies that improve bone regeneration......»»
How the pandemic shaped academic identity: Stories of resilience and struggle
A new book shares the stories of Ph.D. students, early-career researchers, and established academics during the COVID-19 pandemic to shed light on the struggles faced by those in the industry......»»
Hubble captures galaxy cluster ACO S520
A menagerie of interesting astronomical finds are visible in this image from the NASA/ESA Hubble Space Telescope. In addition to several large elliptical galaxies, a ring-shaped galaxy is lurking on the right of the image. A pair of bright stars are.....»»

Using a computational model to study how to land on a planet safely
When a lander descends toward the moon—or a rocky planet, asteroid, or comet—the exhaust plume of the rocket interacts with the surface, causing erosion and kicking up regolith particles. The resulting blanket of dusty debris can create a dangero.....»»
The data that trains AI is under the spotlight — and even I’m weirded out | The AI Beat

Pushing frontiers through upcycling: Eggshell waste for bone graft material
Autologous and allogeneic bone grafts are considered the gold standard when it comes to reconstructing bones, largely due to their bioactive compounds and osteoblastic cells that can generate new bone effectively. However, limited supply, donor-site.....»»
