Joel Harrison Gayford, a marine biologist at James Cook University, in Australia, who specializes in research focused on chondrichthyan evolution and ecology, has published a paper in the journal Royal Society Open Science ...
Phys.org / New catalyst allows asymmetric radical reactions using an engineered ligand
A team of chemists at Southern University of Science and Technology, working with a colleague from Zhejiang University, both in China, has engineered a metal–ligand complex that incorporates a reactive pocket to pre-organize ...
Phys.org / Skin wounds in humans found to heal nearly three times slower than those in other primates
A team of evolutionary scientists, dermatologists and wildlife specialists affiliated with several institutions in Japan, Kenya and France has found that human skin wounds take nearly three times as long to heal as they do ...
Tech Xplore / Metal fatigue in anodes identified as key cause of solid-state lithium battery degradation
A team of materials scientists and engineers affiliated with several institutions in China has found that one of the major reasons solid-state lithium batteries fail over time is metal fatigue in the anode, which contributes ...
Tech Xplore / Reinforcement learning boosts reasoning skills in new diffusion-based language model d1
A team of AI researchers at the University of California, Los Angeles, working with a colleague from Meta AI, has introduced d1, a diffusion-large-language-model-based framework that has been improved through the use of reinforcement ...
Phys.org / Remains found in Great Tumulus of Vergina not Philip II of Macedon, new analysis finds
A team of archaeologists, biologists, chemists and historians affiliated with several institutions in Europe and the U.K. has found evidence that the remains found in the Tomb of Persephone, in the Great Tumulus of Vergina, ...
Phys.org / AI model found to be better than humans at picking puppies that will be good service dogs
A team of computer scientists, AI specialists and veterinary medicine researchers in the U.S. and the U.K., working with the dog training center, The Seeing Eye, Inc., has found that an AI model was better than humans at ...
Phys.org / Snowball Earth: Drone mapping and isotopic dating suggest Marinoan glaciation spanned 4 million years
Scientists at the University of California, Berkeley, and Boise State University have found evidence suggesting that the Marinoan glaciation began approximately 639 million years ago and lasted for approximately 4 million ...
Phys.org / Life on Earth-like planets may emerge rapidly once conditions are favorable
An astronomer at Columbia University is suggesting that because life emerged so soon on Earth after its formation, it may emerge rapidly on Earth-like planets after the right conditions arise in general.
Tech Xplore / Microrobots powered by thin-film actuator can morph, lock shapes and operate untethered
A team of roboticists at Tsinghua University, working with a trio of colleagues from Beihang University, all in China, has designed a new type of microrobot that can continuously transform its shape and "lock" into specific ...
