Polyamines--natural molecules found in every living cell--have become stars in the longevity world for their ability to boost cellular cleanup and support healthy aging. But there's a dark twist: high levels of these same molecules are consistently . ...

Icy moons circling the outer planets may be far more dynamic--and explosive--than they appear. New research suggests that when heat from tidal forces melts their ice shells from below, the sudden drop in pressure could cause hidden oceans to boil ...

Twisting atomically thin magnetic layers does more than reshape their electronics--it can create giant, topological magnetic textures. In chromium triiodide, researchers observed skyrmion-like patterns stretching far beyond the expected moiré scale, ...

Why do we tip--even when we know we'll never see the server again? New research suggests it's not just about rewarding good service, but about social pressure. Some people tip out of genuine appreciation, while others simply follow the norm. But here ...

NYU researchers have found a way to use light to control how microscopic particles assemble into crystals, effectively turning illumination into a tool for shaping matter. By adding light-sensitive molecules to a liquid filled with tiny particles, .. ...

Scientists have uncovered a powerful genetic switch that helps some of the body's most important immune cells grow up properly and keep our organs healthy. The switch, called MafB, guides immature precursor cells as they develop into macrophages, the ...

Inverted perovskite solar cells offer strong potential for scalable, low-cost solar power, but a hidden interface inside the device has limited their performance and durability. Researchers have now introduced crystal-solvate nanoseeds that guide ...

For the first time ever, scientists have uncovered a vast field of tektites in Brazil -- mysterious glassy fragments forged when a powerful extraterrestrial object slammed into Earth about 6.3 million years ago. Named "geraisites" after Minas Gerais, ...

Scientists in Brazil have transformed cocoa waste into a functional chocolate-infused honey packed with antioxidants and natural stimulants. Using ultrasound waves, they enhanced honey's ability to pull beneficial compounds from cocoa shells--no ...

Scientists at Rice University have produced the first full, dye-free molecular atlas of an Alzheimer's brain. By combining laser-based imaging with machine learning, they uncovered chemical changes that spread unevenly across the brain and extend ...
