ETH Zurich scientists have found the holy grail of brewing: the long-sought formula behind stable beer foam. Their research explains why different beers rely on different physical mechanisms to keep bubbles intact and why some foams last far longer . ...

Scientists have identified new anti-aging compounds produced by a little-studied blood bacterium. These indole metabolites were able to reduce inflammation, oxidative stress, and collagen-damaging activity in skin cell cultures. Three of the ...

Researchers analyzed data from over six million people to see how close residents lived to cannabis retailers. Neighborhoods near these shops experienced higher cannabis-related emergency visits compared with those farther away. The effect was ...

Researchers found that repeated head impacts can disrupt a key system that helps the brain wash away waste. In professional fighters, this system initially seems to work harder after trauma, then declines over time. MRI scans revealed that these ...

A large-scale Brazilian study found dangerous levels of toxic metals in popular children's toys, with barium and lead topping the list. Researchers used sophisticated lab methods to identify 21 hazardous elements and test how easily they could be ...

A major review across 73 countries finds that access to antiseizure medications is rising, but safe prescribing isn't keeping pace. Valproate--linked to serious birth defects--remains widely used in many regions despite WHO warnings. Limited access . ...

Researchers have directly observed Floquet effects in graphene for the first time, settling a long-running scientific debate. Their ultrafast light-based technique demonstrates that graphene's electronic properties can be tuned almost instantaneously ...

Researchers have finally assigned a strange 3.4-million-year-old foot to Australopithecus deyiremeda, confirming that Lucy's species wasn't alone in ancient Ethiopia. This hominin had an opposable big toe for climbing but still walked upright in a .. ...

Princeton researchers found that the brain excels at learning because it reuses modular "cognitive blocks" across many tasks. Monkeys switching between visual categorization challenges revealed that the prefrontal cortex assembles these blocks like . ...

Data from over 47,000 dogs reveal that CBD is most often used in older pets with chronic health issues. Long-term CBD use was linked to reduced aggression, though other anxious behaviors didn't improve. The trend was strongest among dogs whose owners ...
