Phys.org / Researchers link the mass extinction of once-dominant marine groups to intolerable heat, diminished oxygen in oceans
A new Stanford-led study offers the clearest picture yet of how some ocean life survived our planet's biggest mass extinction while most animals did not. About 252 million years ago, 96% of marine species and 70% of land ...
Phys.org / Physical laws explain why most flies evolved similar flight, with mosquitoes as outliers
A new study in PLOS Biology of 133 species of flies, mosquitoes and their relatives shows that most species fly in surprisingly similar ways. Physical and aerodynamic laws shape the evolution of their flight behavior more ...
Medical Xpress / Medical AI may look less biased on paper but not in practice, new study finds
Large language models (LLMs) are only as good as the data they learn from. If their training data contains social biases, the models may unintentionally repeat those biases in their responses. As their use increases with ...
Phys.org / JWST finds the most distant barred galaxy candidate in the early universe
Astronomers using the James Webb Space Telescope have identified what may be the most distant barred spiral galaxy ever discovered, dating to a time less than 1.2 billion years after the Big Bang. The paper outlining its ...
Medical Xpress / Artemisinin resistance is rising in East Africa—leaving anti-malarials at risk of failure
Resistance to the main drug in front-line malaria treatments is becoming more widespread across East Africa, according to new research by Imperial College London. The study, published in The Lancet Infectious Diseases, maps ...
Medical Xpress / Forget GLP-1s—GLP-3s show promise in phase 3 weight loss and diabetes trial
Phase 3 clinical trial results (TRANSCEND-T2D-1) published in The Lancet report that retatrutide, an investigational once-weekly injection for diabetes management, can significantly improve blood sugar levels and lead to ...
Phys.org / Jellyfish videos reveal why science content sparks curiosity for some viewers
It can be easy to get sucked into social media for hours on end. Funny, cartoony science videos may be especially interesting, but not to everyone, according to a recent study from the University of Georgia.
Phys.org / Fossils found decades ago reveal extinct 3.5 million-year-old giant salamander species
In the late 1990s in the Ajimu region of Japan's Oita Prefecture, researchers discovered three fossilized vertebrae belonging to the Cryptobranchidae family of giant salamanders. These were embedded in the Tsubusugawa Formation, ...
Tech Xplore / Neutrons track lithium in working solid-state battery, revealing uneven charging
Batteries are part of everyday life, powering everything from phones and laptops to electric cars. Most rechargeable batteries use a liquid to help lithium ions move during charging and discharging. But this liquid can create ...
Phys.org / Scientists just measured the smallest possible contacts for future computer chips
The rise of AI has created an almost insatiable appetite for computing power. Training and running AI systems requires vast numbers of transistors, and engineers are now racing to pack more of them onto every chip. With their ...
Phys.org / Tiny worms reveal backup circuits that keep survival reflexes from failing
A research team led by Professor Chaogu Zheng from the School of Biological Sciences at the University of Hong Kong (HKU), in collaboration with scientists from Princeton University and Columbia University, has discovered ...
Tech Xplore / Programmable metasurface generates dozens of holograms at once
Over the past few decades, engineers have developed various devices that can create holograms, three-dimensional (3D) or two-dimensional (2D) images produced by precisely controlling the shape and direction of traveling light ...
