A horned native bee dubbed Megachile lucifer has been discovered in Western Australia's Goldfields. Identified while surveying a rare wildflower, the species stood out with its unusual "devilish" facial horns. DNA testing confirmed it was previously ...

Scientists have found that a mutation tied to Alzheimer's disrupts the production and quality of exosomes--tiny cell-made communication packets. Cells with the defective SORLA protein generate fewer exosomes and ones far less able to support nearby . ...

Ribosomes don't just make proteins--they can sense when something's wrong. When they collide, they send out stress signals that activate a molecule called ZAK. Researchers uncovered how ZAK recognizes these collisions and turns them into protective . ...

Scientists found that high-flavanol foods can prevent the decline in blood vessel function that occurs after prolonged sitting. Even physically fit men weren't protected unless they had consumed flavanols beforehand. A cocoa drink rich in these ...

Using a precisely aligned pair of laser beams, scientists can now hold a single aerosol particle in place and monitor how it charges up. The particle's glow signals each step in its changing electrical state, revealing how electrons are kicked away . ...

Moss spores survived an extended stay on the outside of the ISS and remained capable of germinating once back on Earth. Their resilience to vacuum, extreme temperatures, and UV radiation surprised the researchers who expected them to perish. The ...

Hunter-gatherers at Poverty Point may have built its massive earthworks not under the command of chiefs, but as part of a vast, temporary gathering of egalitarian communities seeking spiritual harmony in a volatile world. New radiocarbon data and ...

Europe is investing in a coordinated effort to develop high-power optical vortex technologies and train new specialists in the field. The HiPOVor network unites academia and industry to advance applications ranging from material processing to ...

Participants lost more weight on a low-fat vegan diet than on the Mediterranean diet, largely due to eliminating animal foods and reducing oils and nuts. Increased intake of plant foods, even "unhealthy" ones, was strongly associated with greater ...

Scientists are uncovering what makes some carcinomas so resistant: their ability to change identity. Two new studies reveal crucial proteins and structures that could become targets for future therapies. These discoveries deepen understanding of how ...
