The human family tree may be due for a major rewrite. Researchers argue that Australopithecus and Paranthropus should be folded into the genus Homo because new fossils have blurred many of the traits once used to separate them. The proposed shake-up ...

The "Asian Water Tower" is losing roughly 24.2 billion tonnes of groundwater every year, with some of the worst declines hitting densely populated farming regions. Glacier melt may temporarily soften the crisis around the 2060s, but without changes . ...

Extreme experiments have revealed how diamond behaves at crushing pressures beyond those inside Neptune and Uranus, resolving a decades-old conflict between theory and observation. The results could help scientists boost fusion energy output while .. ...

A discarded SpaceX Falcon 9 stage crashed into the Moon on Aug. 5, leaving behind a newly formed crater about 60 feet wide. NASA's Lunar Reconnaissance Orbiter captured detailed images showing bright and dark streaks of debris blasted across the ...

Spain's total solar eclipse delivered an unexpected sight: a corona glowing gold instead of its usual pearly white. Because the Sun was setting, its light passed through more atmosphere, while smoke from nearby wildfires filtered out even more blue . ...

More than 1,000 genetic switches behave differently in male and female immune cells, helping explain why women are much more vulnerable to autoimmune diseases such as lupus. Female immune systems appear genetically tuned for stronger inflammatory ...

Researchers have developed a new way to turn ordinary antibodies into tiny disease-fighting molecules that can work inside human cells, potentially opening new paths for treating Alzheimer's, Parkinson's, Huntington's disease, and motor neurone ...

MIT physicists found that two electronic phases inside the same quantum material emerge through surprisingly different mechanisms--one smoothly and the other in expanding pockets resembling growing ice crystals. The discovery could help explain how . ...

The brain has a remarkably flexible system for handling uncertainty and changing situations. Researchers found that the frontoparietal cortex constantly shifts how it communicates with other brain regions depending on what information is needed to .. ...

Scientists have found evidence that the effects of a mother's age on her offspring may be driven by reversible changes in gene activity rather than permanent DNA damage. The discovery raises the fascinating possibility that biological information ...
