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 compa...
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 decl...
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 hazard...
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 man...
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 electro...
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...
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 t...
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 improv...
Researchers discovered why bird flu can survive temperatures that stop human flu in its tracks. A key gene, PB1, gives avian viruses the ability to replicate even at fever-level heat. Mice experiments...
Long-term inhalation of toxic air appears to dull the protective power of regular workouts, according to a massive global study spanning more than a decade and over a million adults. While exercise st...
Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in nuclear DNA. These lesions disrupt energy production and activate stress-resp...
Using intense X-rays, researchers captured a buckyball as it expanded, split and shed electrons under strong laser fields. Detailed scattering measurements showed how the molecule behaves at low, medi...
