Scientists may have cracked the case of whether a seven-million-year-old fossil could walk upright. A new study found strong anatomical evidence that Sahelanthropus tchadensis was bipedal, including a ligament attachment seen only in human ancestors. ...

Researchers have uncovered thousands of preserved metabolic molecules inside fossilized bones millions of years old, offering a surprising new window into prehistoric life. The findings reveal animals' diets, diseases, and even their surrounding ...

Scientists are uncovering new clues that a cosmic explosion may have rocked Earth at the end of the last ice age. At major Clovis-era sites, researchers found shocked quartz--evidence of intense heat and pressure consistent with a comet airburst ...

Moss may look insignificant, but it can carry a hidden forensic fingerprint. Because different moss species thrive in very specific micro-environments, tiny fragments can reveal exactly where a person has been. Researchers reviewing 150 years of ...

A powerful 7.4-magnitude earthquake struck northern Chile in July 2024--and it wasn't supposed to be that strong. Unlike Chile's infamous shallow "megathrust" quakes, this one ruptured deep inside the Earth, where shaking is usually weaker at the ...

Spruce bark beetles don't just tolerate their host tree's chemical defenses--they actively reshape them into stronger antifungal protections. These stolen defenses help shield the beetles from infection, but one fungus has evolved a way to neutralize ...

A strange little snake fossil found on England's south coast has finally revealed its secrets--more than 40 years after it was discovered. The newly named Paradoxophidion richardoweni lived around 37 million years ago, during a time when Britain was ...

Microplastics in rivers, lakes, and oceans aren't just drifting debris--they're constantly leaking invisible clouds of chemicals into the water. New research shows that sunlight drives this process, causing different plastics to release distinct and ...

Scientists have discovered a clever way to turn carrot processing leftovers into a nutritious and surprisingly appealing protein. By growing edible fungi on carrot side streams, researchers produced fungal mycelium that can replace traditional plant ...

Environmental change doesn't affect evolution in a single, predictable way. In large-scale computer simulations, scientists discovered that some fluctuating conditions help populations evolve higher fitness, while others slow or even derail progress. ...
