Phys.org / 'Oldest octopus' fossil is no octopus at all, scans reveal
A famous 300-million-year-old fossil that was thought to be the world's oldest octopus—even featuring in the Guinness Book of Records—has turned out to be something else altogether. In what amounts to a case of mistaken identity, ...
Phys.org / Underwater architects: Nest-building in cichlids reveals more than hardwired instinct
We associate nests with shelter, warmth, and a safe retreat—and usually picture a bird's nest made out of twigs, grass and feathers. Yet many other animals take advantage of such refuges, with nests being built by a diversity ...
Tech Xplore / A hardware-software co-design can efficiently run AI on edge devices
A new hardware-software co-design increases AI energy efficiency and reduces latency, enabling real-time processing of continuous data streams like video or sensor feeds. The neuromorphic approach unlocks the ability to run ...
Phys.org / AMOC collapse could turn Southern Ocean into carbon source, adding 0.2°C to global warming
A shutdown of the Atlantic Meridional Overturning Circulation (AMOC) could trigger a substantial release of stored ocean carbon into the atmosphere over hundreds of years, according to a new study that simulated such a collapse ...
Phys.org / Subaru Telescope sheds light on Jupiter Trojan asteroids' color mystery
Observations conducted with the Subaru Telescope and its first-generation wide-field camera, Suprime-Cam, have revealed new insights into the relationship between the color and size of Jupiter Trojan asteroids.
Tech Xplore / After Anthropic's Mythos AI uncovers thousands of zero-day bugs, top US officials huddle with bank CEOs
The heads of America's biggest banks met this week with Federal Reserve Chairman Jerome Powell and Treasury Secretary Scott Bessent to weigh the security implications of a new artificial intelligence system developed by Anthropic, ...
Medical Xpress / Making the case for over-the-counter abortion pills: Study finds most people can accurately self-screen
Currently, in U.S. states where abortion remains legal, women have to visit specialized clinics to access in-person medication abortion, as drugs like mifepristone and misoprostol are not available over-the-counter (OTC). ...
Phys.org / Bacteria from bumblebees can produce vitamin B₂ in soya drinks
Researchers at DTU have developed a new method that can reduce the time needed to find new bacteria for fermentation. They have now identified a bacterium that can be used both for acidification and to increase the vitamin ...
Medical Xpress / Epigenetic changes at birth are associated with an infant's microbiome and neurodevelopment
The gut microbiome and epigenetics—molecular switches that turn genes on or off—are intertwined, and both contribute to neurodevelopment, finds a study published in Cell Press Blue. The researchers showed that epigenetic ...
Phys.org / Giant jars, ancient bells, buried bones and a mystery that endures
Helping to preserve artifacts, some potentially 2,000 years old, was an irresistible privilege. Since 2016, an Australian-Lao team led by Louise Shewan, Dougald O'Reilly and Thonglith Luangkhoth has conducted archaeological ...
Phys.org / Tropical trees are more neighborly than trees further from the equator, study finds
Tropical trees are better neighbors than trees in temperate forests, according to a study published in the journal Nature by researchers from 29 different institutions including the Smithsonian Tropical Research Institute ...
Medical Xpress / Molecular maps reveal how allergic reactions work and a new way to block them
Allergy affects more than one billion people worldwide—and the number is rising. For many, it means mild symptoms such as itching and a runny nose. For others, it can develop into life-threatening reactions. Now, two new ...
