Scientists have uncovered a new explanation for what powers Yellowstone and other supervolcanoes. Instead of a deep plume rising from near Earth's core, a broad "mantle wind" may push hot rock beneath Yellowstone, generating magma closer to the ...

Astronomers studying the rare supernova SN 2021yfj discovered material from one of the deepest layers of a dying star, providing a rare look at its hidden interior. The finding confirms key theories about how massive stars forge the elements that ...

Aging may trigger the appearance of specialized stem cells that supercharge the body's ability to create new belly fat. The discovery reveals a potential biological driver of middle-age weight gain and a promising target for future anti-obesity ...

Two newly confirmed "super-puff" planets are so diffuse that they are less dense than cotton candy, despite being about the size of Jupiter. Their rare orbital relationship and enormous, lightweight atmospheres could provide valuable clues about how ...

Scientists exploring ancient seafloor rocks in Morocco discovered mysterious wrinkle patterns where they were never expected to occur. These structures are normally linked to microbial mats in shallow, sunlit waters, yet the rocks formed hundreds of ...

The battle between butter and margarine comes down to chemistry. Butter's naturally occurring fats create rich flavors, golden browning, and flaky baked goods, while margarine's modified plant oils offer consistency and a longer shelf life. Although ...

A new study reveals that goldfish can do far more than survive in the wild--they can fundamentally reshape freshwater ecosystems. Researchers found they cloud water, damage food webs, and hurt native fish populations, sometimes triggering major ...

A new study found that fructose and glucose may look the same on a nutrition label, but the brain treats them very differently. In mice, glucose strongly reduced activity in hunger-promoting brain cells, while fructose had a much weaker effect. High ...

The capture of a juvenile great white shark in Spain has provided fresh evidence that the Mediterranean's elusive "ghost" population of great whites still survives. Researchers reviewing 160 years of records say the discovery could even hint that the ...

Scientists have discovered a "ballista spider" that builds a spring-powered silk trap designed specifically to catch aggressive green tree ants. The ant unknowingly triggers the mechanism itself, launching into the spider's web in one of nature's ...
