A mysterious particle overlooked for decades may hold the key to why matter survived the Big Bang, allowing stars, planets, and life to exist. Scientists believe this forgotten neutrino reshaped the early universe and may have left detectable ...

Scientists have discovered that trees can sense their own shape and straighten their trunks using specialized wood that acts like opposing muscles. This remarkable ability helps trees maintain their posture and could lead to stronger forests, better ...

Scientists have uncovered a hidden mechanism that allows high-cholesterol diets to undermine the body's natural cholesterol defenses, and blocking it dramatically lowered harmful LDL cholesterol in mice. Even more promising, an experimental drug ...

Scientists at Johns Hopkins have uncovered a crucial missing link between a common gut bacterium and colorectal cancer, solving a mystery that has puzzled researchers for nearly two decades. The bacterium, Bacteroides fragilis, produces a toxin that ...

A remarkable 4,000-year-old defensive structure discovered in Morocco is rewriting what scientists thought they knew about ancient North African civilizations. The massive fortifications reveal unexpectedly sophisticated prehistoric societies and ...

Scientists have discovered a surprising mechanism that allows certain metals to resist cracking at temperatures as low as -253°C (-424°F), when similar materials typically become dangerously brittle. Instead of breaking, two experimental alloys ...

A Neanderthal who died 75,000 years ago may have been killed by a wooden spear deliberately aimed at the heart, revealing rare evidence of prehistoric violence. A circular hole in the shoulder blade suggests the weapon pierced the chest and caused a ...

Scientists have discovered a bizarre bacterial defense system that works almost completely backward from anything seen before. Unlike typical bacterial immune systems that keep a deadly toxin under control until a virus attacks, this unusual ...

Scientists at Johns Hopkins University have uncovered a surprising process that helps humans develop sharp vision before birth, challenging decades of assumptions about how the eye forms. Using miniature human retinas grown in the lab, researchers .. ...

Scientists have recreated a primordial state of matter from the dawn of the universe by colliding oxygen nuclei at nearly the speed of light. The surprising results show that this exotic substance can form in smaller, lower-energy collisions than ...
