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. …
Scientists crushed diamond beyond Neptune-like pressures—and solved a 20-year mystery
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 …
A SpaceX rocket smashed into the Moon — NASA just revealed the …
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 …
This total solar eclipse looked strangely golden — here’s why
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 …
More than 1,000 genetic switches reveal why female immunity is different
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 …
AI-designed “intrabodies” could unlock new treatments for Alzheimer’s, Parkinson’s and MND
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 …
MIT physicists discover electrons rebuilding like ice inside a quantum material
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 …
Researchers reveal deeper workings of brain’s information hub
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 …
A mother’s age can shape her offspring without changing their DNA
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 …
Coffee drinkers have less fat, more muscle, and surprising hormone differences
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 …
Scientists turn probiotic bacteria into tiny drug factories for pancreatic cancer
Engineered probiotic bacteria were able to infiltrate pancreatic tumors, stimulate cancer-fighting immune cells, and slow tumor growth in animal studies. Even more strikingly, the treatment …
Tiny quantum engines reveal useful energy hiding in “waste heat”
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 …
Pollen has a surprising problem — and honeybees have found a way …
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. …
This 23-foot crocodylian may have ruled South America’s food chain
