Is consciousness something the brain produces, or is it woven into the fabric of reality itself? Renowned neuroscientist Christof Koch is challenging long-held scientific assumptions by confronting the "hard problem" of consciousness -- why and how . ...

Your brain's "stop eating" signal may come from an unexpected source. Researchers found that astrocytes--once thought to just support neurons--actually play a key role in controlling appetite. After a meal, glucose triggers tanycytes, which send ...

A newly discovered group of tarantulas is so bizarre that scientists had to invent a whole new genus--Satyrex--to describe them. With unusually long mating appendages and fierce, hissing defenses, these spiders are as strange as they are intimidating ...

Scientists have identified a little-known receptor, GPR133, as a powerful regulator of bone strength. By activating it with a newly discovered compound called AP503, they were able to boost bone density in mice and counteract osteoporosis-like damage ...

Scientists have taken a major step toward probing one of physics' biggest mysteries--how gravity and quantum mechanics fit together--by creating the first unified way to detect tiny "ripples" in spacetime itself. These subtle fluctuations, long ...

A massive new analysis of over 1,700 languages shows that some long-debated "universal" grammar rules are actually real. By using cutting-edge evolutionary methods, researchers found that languages tend to evolve in predictable ways rather than ...

Scientists in Canada have uncovered a surprising weakness in glioblastoma, one of the deadliest brain cancers. They found that certain brain cells--once believed to only support healthy nerves--can actually help tumors grow by sending signals that .. ...

Scientists have uncovered a powerful new clue in the mystery of brain aging: a single protein called FTL1. In aging mice, higher levels of this protein weakened connections between brain cells and led to memory decline. But when researchers reduced . ...

Mars may look like a quiet, dusty world, but it's actually buzzing with hidden electrical activity. Powerful dust storms and swirling dust devils generate static electricity strong enough to spark faint glowing discharges across the planet, ...

A hidden Roman sanctuary discovered beneath Frankfurt is offering rare clues about ancient rituals, including possible human sacrifice. With major funding secured, scientists are now racing to uncover how this mysterious, multi-god cult site operated ...
