Phys.org / Giant kangaroos survived until 6,500 years ago on the New Guinea coast
Roughly 50,000 years ago, a kangaroo unlike any alive today lived in the mountain rainforests of New Guinea.
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 / 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, ...
Phys.org / Nanoplastics found in Antarctic soils for first time, suggesting long-range atmospheric transport
Microplastic contamination has been a much-discussed topic over the last several years, but contamination from even smaller plastic particles represents another pressing issue. Nanoplastics—defined as being under a micrometer ...
Phys.org / NASA space telescope maps magnetic fields of 'Lighthouse' pulsar
For the first time, scientists have used NASA's IXPE (Imaging X-ray Polarimetry Explorer) to directly measure the magnetic fields of PSR J1101−6101, a pulsar located within what is often referred to as the Lighthouse Nebula. ...
Phys.org / China takes a page from SpaceX and recaptures the first stage of a rocket to reuse it
China successfully recaptured the first stage of a rocket after a launch on Friday in a breakthrough for the country's space program, state media said.
Medical Xpress / Fasting primes gut microbiome to improve intestinal recovery after radiation treatment
A new preclinical study from the University of Texas MD Anderson Cancer Center has identified a gut bacterium that, when combined with short-term fasting, helps prepare the small intestine to regenerate more effectively after ...
Phys.org / The oldest deliberately collected fossil ichthyosaur was discovered in Roman Britain around 1,800 years ago
Around 1,800 years ago, a fossilized spinal bone lay on the windswept beaches of Roman Britain until a curious passerby picked it up and carried it far away, only to drop it in a pit.
Phys.org / New test certifies quantum measurements that simpler methods cannot mimic
Proving that one quantum measurement is more powerful than another has long been difficult. Physicists from Heinrich Heine University Düsseldorf, Lund University and the University of Innsbruck have now developed and demonstrated ...
Tech Xplore / Amid criticism, Meta reins in new AI tool that automatically accessed public Instagram images
Meta has pulled the plug on a feature of a recently launched AI tool following criticism that it made Instagram accounts fodder for use in creating AI-generated images.
Phys.org / New model maps solar storms across 1 million miles around Earth
A team at the Applied Physics Lab is working to understand the complex science behind predicting invisible threats that can quickly cripple electric grid infrastructure on Earth.
Phys.org / Evidence of elusive high-energy chiral graviton excitations in quantum Hall systems
Electrons, negatively charged particles, sometimes coordinate their movements in ways that produce certain collective excitations referred to as quasiparticles. One case in which this occurs is the quantum Hall effect, a ...
