Ancient fern savannahs may have transformed parts of Europe into a wildfire-prone inferno during the end-Triassic mass extinction. New fossil evidence suggests the ferns repeatedly regrew after fires, creating fresh fuel that helped prolong the ...
Miniature brain models grown from patients’ cells revealed striking differences in how Alzheimer’s-related tissue responds to an antidepressant. The organoids and the particles they release could eventually guide more personalized treatments and ...
Researchers discovered a proton-assisted mechanism that greatly improves how triplet energy moves between quantum dots and nearby molecules. The proton briefly shifts position, helps coordinate electron movement, and then returns to where it ...
Scientists have found a way to revive vancomycin, a powerful antibiotic that some dangerous bacteria have learned to resist. Instead of creating an entirely new drug, researchers paired vancomycin with a small molecule called pghi-4, which blocks a ...
Researchers are applying evolutionary theory to cancer by changing treatments before tumors have time to develop resistance. Mathematical models suggest that rapid, carefully timed switches between multiple therapies could improve cure ...
A single dose of psilocybin produced measurable changes in brain activity and possible changes in brain structure that lasted for up to a month. Participants who experienced the greatest increase in flexible, varied brain activity also reported more ...
China’s Chang’e-6 samples have uncovered a surprising difference between the Moon’s two hemispheres. Solar wind particles penetrated deeper into the far-side soil because Earth’s ...
Astronomers have found the first confirmed atmosphere around a rocky planet in another star’s habitable zone. The planet, LHS 1140 b, revealed its atmosphere through helium slowly leaking into ...
Ancient DNA from China’s vast 4,000-year-old Shimao settlement is revealing how one of East Asia’s earliest complex societies was organized. Researchers found that its people were largely ...
A newly discovered turning point in the Sun’s 11-year cycle could allow scientists to predict future solar activity years earlier than before. At this “switch-off” point, the most violent space ...
Scientists studying decades of pygmy sperm whale strandings have uncovered three previously unknown types of Helicobacter bacteria hiding in the animals’ stomachs. All four infected whales showed ...
Scientists uncovered how influenza A commandeers human cells, including a surprising strategy that dissolves tiny structures in the nucleus and releases proteins the virus may use to reproduce. The detailed molecular map could reveal new drug ...

For most adults, a daily caffeine habit may be safer for the heart than many people assume. A new American Heart Association review found that up to 400 milligrams of caffeine a day, roughly three to ...

Watching television very often in midlife may be linked to troubling brain changes decades later. In a study of about 1,700 adults, frequent TV viewers later showed smaller brain regions involved in ...

Scientists have created a programmable optical chip that can slow light on demand, giving engineers far greater control over how optical signals propagate through a circuit. The technology could ...

The asteroid that wiped out the dinosaurs was likely an exceptionally rare CO chondrite from a distant region of the solar system. Its unusual chemistry suggests that planet-cooling dust and debris, ...

A protein called SORLA may act as a powerful defense against the toxic tau tangles involved in Alzheimer’s disease. Mice with extra SORLA had less tau accumulation, less brain atrophy, and ...

Oxygen is disappearing from oceans, lakes, rivers, and coastal waters at an alarming rate, threatening aquatic life and weakening the natural processes that help regulate Earth’s climate. ...

Scientists have discovered a hidden warning sign of skin damage that appears before collagen fibers visibly thin, break, or lose their connections. Using advanced light-based techniques, the team ...

A large laboratory study found that many commonly used sweeteners can directly change the growth of gut bacteria. Researchers identified more than 100 cases in which sweeteners behaved differently ...

A catastrophic asteroid breakup may have triggered a huge wave of impacts across the inner solar system about 800 million years ago. The debris was launched from near a gravitational gateway ...

JWST has captured unusually detailed images of gas feeding the supermassive black hole at the center of NGC 4696. A vast filament appears to funnel material into an 800-light-year-wide spinning disk, ...

A growing Cyclospora outbreak has sickened more than 400 people in four states, and investigators are still searching for the contaminated food responsible. The CDC warns the actual number of cases ...

An ancient sea worm may hold the secret to a whole new category of natural materials. Its jaws combine proteins and metal ions in a way that gives them metal-like strength and unusual mechanical ...

Going to the cinema, visiting museums, or attending concerts may do more than entertain. Researchers found that older adults who regularly participated in cultural activities tended to have bodies ...

An unusual leopard gecko that naturally develops aggressive tumors may become an important new model for cancer research. Scientists found its tumors share key genetic changes with human cancers, ...

A deadly fungus has wiped out amphibian populations around the globe, yet some mysteriously recover. Researchers discovered that survivors develop powerful immune defenses while they are still ...

A team of mathematicians used whimsical "silly sprinklers" to solve a physics mystery that has puzzled scientists for decades. Their experiments showed that the rotation of both normal and ...

A new review highlights exciting progress in atomically thin quantum materials where light and magnetism work together in ways never before possible. In these materials, light-generated excitons can ...

Four nearby white dwarf stars have been discovered hiding in plain sight beside brighter red dwarf companions. Hubble's ultraviolet observations finally revealed the long-hidden stellar ...

NASA's PACE satellite captured the Black Sea glowing turquoise during its annual phytoplankton bloom. The vivid color comes from massive numbers of coccolithophores, microscopic organisms whose ...

A new book claims AI has been built on a flawed assumption dating back to Alan Turing's famous 1950 paper. Peter J. Denning argues that the most important parts of human intelligence, including ...
