Phys.org / Scavenging linked to virus variety in wild birds
The scavenging behavior of many wild birds plays an important role in the type, number and variety of viruses they have, a new University of Otago–Ōtākou Whakaihu Waka-led study has found.
Phys.org / Learning without a brain—how bacteria store memories and remember the past like artificial neural networks
Learning is often thought to require a brain. But learning is a broad concept that does not necessarily depend on neurons.
Phys.org / 'Quiet' pulsar suddenly reveals three glitches in 15 years of observations
Using more than 15 years of observations from the Parkes radio telescope, astronomers detected three rotational glitches in the pulsar PSR J1637−4642—a young neutron star that had shown no signs of glitches since its discovery. ...
Phys.org / English, but make it TikTok: How social media is reshaping language
Give, eat, cook and serve are everyday English words. On TikTok, they're doing something different.
Medical Xpress / Cardiovascular-kidney-metabolic disease risk factors can be identified in kids as young as eight
Risk factors for cardiovascular-kidney-metabolic disease, a condition comprising heart disease, kidney disease, diabetes and obesity, can be identified in children as young as 8, UTHealth Houston researchers found.
Tech Xplore / China, Iran among countries that have used AI to aid spying, Anthropic says
Anthropic said Thursday it shut down multiple cases of state-sponsored surveillance operations that used its artificial intelligence (AI) models and warned that governments and state-aligned actors are increasingly using ...
Phys.org / AI pinpoints when fish reach their thermal limit
Researchers have developed an AI-based system that automatically and objectively detects the moment when fish experience loss of equilibrium (LOE) due to temperature stress. The system combines DeepLabCut, a deep-learning ...
Tech Xplore / Anthropic says it blocked misuse of its AI that could have supported biological weapons
Anthropic said Thursday it has blocked efforts by bad actors to use its artificial intelligence models for malicious activity such as cyberattacks, surveillance, and research that could have led to biological weapons.
Medical Xpress / New imaging combines light and sound to watch brain oxygen supply in real time
The brain is a black box of densely packed neurons, blood vessels and immune cells, all locked away in a sealed skull. WashU's Song Hu has dedicated his career to unlocking that puzzle box by developing new ways to "see" ...
Medical Xpress / Protein shape shift reveals how the mpox virus begins replicating
The way two mpox virus proteins change shape as they bind together acts like a switch that starts the process of viral replication, a study led by researchers at the Blavatnik Institute at Harvard Medical School reveals. ...
Phys.org / Hubble and Webb find that far-out solar system objects 'remember' the past
For the first time, scientists used the combined power of NASA's Hubble and James Webb Space Telescopes to study some of the most far-flung bodies in our solar system, trans-Neptunian objects (TNOs). Some are the smallest ...
Phys.org / Electrochemical system extracts pure hydrogen from ammonia at substantially lower temperatures
As a liquid that is easily stored and transported, ammonia (NH3) is an attractive carrier for hydrogen, which is used in fuel cells, semiconductor manufacturing, chemical processing and other applications. However, breaking ...
