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 sunlight-powered material can convert visible light into higher-energy UV light, overcoming a challenge that has frustrated scientists for years. The breakthrough could enable cleaner air purification, solar-driven chemistry, and advanced ...

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 ...

A new study suggests Earth may have been sending tiny hitchhikers to Venus for billions of years. Researchers found that asteroid impacts could launch microbes into space, where some might survive the journey and end up suspended in Venus' clouds. If ...

Astronomers may have witnessed one of the rarest and most dramatic cosmic events ever seen: a long-sought intermediate-mass black hole ripping apart a dense white dwarf star and devouring it. The Einstein Probe space telescope caught the explosion in ...
