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 . ...

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 .. ...

Coffee drinkers may be getting more than an energy boost. A Finnish study found that people who drank more coffee tended to have less total and abdominal fat, more muscle, and healthier metabolic markers despite having similar BMIs. Higher coffee ...

A tiny machine made from just an atom and particles of light may sound impossibly simple, but it raises a surprisingly difficult question: what counts as heat, and what energy can still do useful work? University of Basel researchers have developed a ...

Honeybees can apparently detect when their food has the wrong balance of essential nutrients and adjust how much they eat to avoid potentially harmful excesses. They also transform pollen into remarkably well-balanced "baby food" for their larvae, .. ...

Miocene South America was packed with giant prey--and the predators hunting them were just as spectacular. Fossil bite marks suggest crocodylians, especially the enormous Purussaurus neivensis, were more important predators than mammals in this ...

A tomb in Egypt's Theban Necropolis reveals a surprisingly organized story of burial, reuse, and changing beliefs spanning hundreds of years. Researchers found 16 mummified people, the remains of at least four more, and a mummified dog, with burials ...

Silver nanoparticles can precisely slice DNA and create longer "sticky ends," helping genetic fragments join up to five times more efficiently than conventional methods. The breakthrough could eventually simplify the construction of large DNA ...
