Fish oil has long been praised as brain-boosting, but new research suggests the story may be more complicated. Scientists found that in people with repeated mild head injuries, a key omega-3 fatty acid in fish oil--EPA--may actually interfere with .. ...

For ages, wall lizards coexisted in three distinct color types, each with its own strategy for survival. Now, a powerful green variant is taking over. These dominant "Hulk" lizards are outcompeting the others, causing yellow and orange morphs to ...

Beneath East Africa's Turkana Rift, scientists have found the crust is thinning to a critical point, suggesting the continent is gradually breaking apart. This "necking" process marks an advanced stage of rifting that could eventually lead to a new . ...

A gut bacterium may be quietly fueling depression through an unexpected chemical twist. Researchers found that when Morganella morganii interacts with a common pollutant, it produces a molecule that triggers inflammation--something strongly linked to ...

A major physics experiment has uncovered evidence for a strange new form of matter, where a fleeting particle gets trapped inside a nucleus. This exotic state may reveal how mass is generated, suggesting that particles can weigh less when surrounded ...

In the chaotic first moments after the Big Bang, ripples in spacetime may have done more than just echo through the cosmos--they could have helped create dark matter itself. New research suggests that faint, ancient gravitational waves might have ...

Giant, fearsome octopuses may have once ruled the ancient seas, according to new research that flips the script on their evolutionary past. By uncovering exquisitely preserved fossil jaws hidden inside rock, scientists revealed that early octopuses . ...

Ancient Earth once buzzed with enormous dragonfly-like insects, and scientists long thought high oxygen levels made their size possible. A new study overturns that idea, revealing insect flight muscles weren't constrained by oxygen after all. Their . ...

Before seedlings can photosynthesize, they depend on fatty acids--and on peroxisomes to process them. Researchers discovered that the protein PEX11 not only helps these structures divide but also controls their size during early growth. When key ...

Scientists are grappling with a cosmic mystery: why does the Universe behave differently on massive scales compared to our own solar system? While distant galaxies reveal clear signs of something bending the rules of gravity--often attributed to dark ...
