Phys.org / REGALADE: The most extensive catalog of galaxies for modern astronomy
An international team of scientists led by the Institute of Cosmos Sciences at the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC) has presented REGALADE, an unprecedented catalog covering ...
Dialog / Natural selection can work at many levels, from molecules to ecosystems
When most people think about natural selection, they imagine individuals competing with one another: The fastest animal escapes predators, the strongest plant produces more seeds, and the most resistant bacteria better survive ...
Phys.org / Colonists dredged away Sydney's natural oyster reefs. Now, scientists know how best to restore them
New research has identified optimal design for artificial habitats to support restoration of oyster reefs, based on a detailed understanding of natural oyster reef geometry. Published in the global journal Nature, the Sydney-based ...
Phys.org / Scientists reveal best- and worst-case scenarios for a warming Antarctica
The climate crisis is warming Antarctica fast, with potentially disastrous consequences. Now scientists have modeled the best- and worst-case scenarios for climate change in Antarctica, demonstrating just how high the stakes ...
Tech Xplore / AI 'blind spot' could allow attackers to hijack self-driving vehicles
A newly discovered vulnerability could allow cybercriminals to silently hijack the artificial intelligence (AI) systems in self-driving cars, raising concerns about the security of autonomous systems increasingly used on ...
Tech Xplore / Robot hand approaches human-like dexterity with new visual-tactile training
Human hands are a wonder of nature and unmatched in the animal kingdom. They can twist caps, flick switches, handle tiny objects with ease, and perform thousands of tasks every day. Robot hands struggle to keep up. They typically ...
Medical Xpress / MRI antenna can boost image quality and shorten scan times—without changing existing machines
Magnetic resonance imaging (MRI) is one of medicine's most powerful diagnostic tools. But certain tissues deep inside the body—including brain regions and delicate structures of the eye and orbit that are of particular ...
Phys.org / How choices made by crowds in a train station are guided by strangers
In crowds, most people are strangers to you, and everyone else for that matter. However, until now, the effect of stranger-to-stranger interactions on the choices people make in crowds has not been properly examined. Ziqi ...
Phys.org / First-ever shark recorded in Antarctic waters filmed at 490 meters in near‑freezing water
An ungainly barrel of a shark cruising languidly over a barren seabed far too deep for the sun's rays to illuminate was an unexpected sight.
Phys.org / Impact-formed glass provides evidence of cosmic collision in Brazil about 6 million years ago
For the first time in Brazil, researchers have identified a field of tektites. These are natural glasses formed by the high-energy impact of extraterrestrial bodies against Earth's surface. These structures, named geraisites ...
Medical Xpress / Newly found immune cells link strep throat to psoriasis
A common strep throat infection can trigger guttate psoriasis by altering the behavior of key immune cells, according to a new study from Karolinska Institutet published in eBioMedicine. The findings suggest how an infection ...
Phys.org / Quantum trembling: Why there are no truly flat molecules
Traditional chemistry textbooks present a tidy picture: Atoms in molecules occupy fixed positions, connected by rigid rods. A molecule such as formic acid (methanoic acid, HCOOH) is imagined as two-dimensional—flat as a ...
