A UCLA study found that long-term exposure to a common pesticide was linked to more than 2.5 times the risk of Parkinson's disease. Scientists also uncovered how the chemical damages brain cells and identified a promising way to protect them.

Scientists have built a groundbreaking molecular motor that spins in either direction using electricity, inspired by a machine invented more than 2,000 years ago. Even more remarkably, its rotation can boost electrical conductivity by up to 100 times ...

Scientists at the University of Virginia have developed a promising new strategy to fight glioblastoma, one of the deadliest and most difficult-to-treat forms of brain cancer. Their experimental approach combines focused ultrasound, tiny ...

A 17- to 18-million-year-old ape fossil discovered in Egypt is challenging long-held beliefs about where the ancestors of humans and other modern apes first evolved. Scientists now suspect that North Africa and the Middle East, rather than East ...

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 ...

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 ...
