Insects quietly hold much of the natural world together, yet conservation efforts are overlooking the tropical regions where more than 80 percent of insect species live. Monash University researchers have developed a global framework to close this .. ...

Scientists found that a tiny atomic structure that forms on nickel oxide during methane conversion is more effective than the metallic nickel long believed to drive the reaction. The discovery allowed a low-nickel catalyst to rival one containing 10 ...

Volcanic rocks in Colombia are rewriting the timeline of the collision between Central and South America. Their magnetic signatures show that major tectonic deformation had already weakened by the late Miocene, suggesting the most intense collision . ...

A new analysis of more than 1,700 supernovae is questioning whether the universe is really accelerating at all. After accounting for the ages of the stars that produce these explosions, researchers found signs that cosmic expansion may actually be .. ...

Astronomers have detected an exceptionally faint hydrogen radio signal from billions of light-years away using South Africa's MeerKAT telescope. Instead of finding galaxies one at a time, the technique measures their combined hydrogen glow across ...

Scientists found that caffeine activates an ancient cellular energy system involved in stress resistance, DNA repair, and growth. The discovery could help explain caffeine's links to healthier aging and may point toward new ways to target the same .. ...

Researchers discovered that combinations of toxin-blocking proteins naturally found in rattlesnake blood can powerfully neutralize venom from several dangerous snake species. In lab tests, the mixtures were about 10 times more potent than a current . ...

More than 1,200 genetic variants have been linked to the Big Five personality traits, and many of the same variants are also associated with health, longevity, careers, income, and everyday habits. The findings reveal a surprisingly wide genetic ...

Semaglutide, the drug behind Ozempic and Wegovy, may have benefits that extend well beyond weight loss and diabetes. In a large Swedish study of nearly 15,000 people with bipolar disorder, its use was linked to a 21% lower risk of psychiatric ...

Scientists have identified a giant new dinosaur from Brazil that reached about 20 meters long and lived 120 million years ago. Its surprising evolutionary ties to a Spanish dinosaur suggest its ancestors crossed ancient land connections between ...
