Scientists discovered that extreme deep-sea pressure squeezes valuable nutrients out of sinking organic particles, providing an unexpected food source for ocean microbes. The finding could rewrite our understanding of both deep-ocean ecosystems and . ...

Practice may do more than make perfect. Researchers found that extensive training physically reorganizes the brain, allowing learned tasks to bypass the prefrontal cortex and run through specialized circuits instead. By freeing the brain's "thinking" ...

Why do beaches today have seashells from clams and snails instead of brachiopods? A new study suggests the answer lies in Earth's greatest mass extinction, when warming oceans and falling oxygen levels wiped out animals that couldn't adapt. Species . ...

Gold may have a secret self-defense system that helps it resist tarnishing. Researchers discovered that atoms on gold surfaces reorganize themselves into patterns that block oxygen from reacting with the metal, suppressing oxidation by up to a ...

Two striking Asian praying mantis species that have rapidly spread across Europe have now been officially classified as invasive, raising new concerns about their impact on native wildlife. Boosted by climate change and urban environments, these fast ...

Many of the body's biggest flaws are the result of evolution building on old designs instead of starting over. Our spine, eyes, teeth, pelvis, and even certain nerves all reveal compromises that worked well enough for survival but still leave us ...

Scientists have discovered a previously unknown fossil goose that challenges a decades-old theory about the evolution of New Zealand's birds. The find suggests the country's giant flightless geese evolved from much more recent arrivals, revealing a . ...

A next-generation pesticide designed to kill crop pests may also be interfering with the reproductive health of bumblebees. Researchers discovered that low-dose exposure to sulfoxaflor changed gene activity, especially in tissues involved in ...

Mount Etna has long puzzled geologists because it doesn't fit any of the three classic ways volcanoes are thought to form. A new study suggests it may instead be fueled by ancient pockets of magma that are pushed upward through cracks created by ...

Scientists have identified new clues that could help astronomers spot one of the most famous hypothetical alien megastructures: a Dyson sphere. The study finds that red dwarfs and white dwarfs are the most promising stars to examine, since advanced . ...
