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 n…
Read story →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…
Read story →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 detecta…
Read story →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 fores…
Read story →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 experimenta…
Read story →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…
Read story →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 societ…
Read story →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 a…
Read story →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 an…
Read story →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 unusu…
Read story →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, res…
Read story →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 collisio…
