Scientists stunned as volcano cloud starts destroying methane
The Hunga Tonga eruption may have triggered a surprising chemical reaction that destroyed some of the methane released into the atmosphere. Scientists say the discovery could reshape estimates of methane pollution and inspire new methods for slowing ne…
Smelling chocolate helped men complete more reps without feeling more tired
Simply smelling chocolate helped men complete more leg extension repetitions without making the workout feel harder, with dark chocolate producing the strongest effect. The researchers think familiar food aromas may influence appetite and motivation by…
This Australian cave hid 25,000 years of ritual secrets
Microscopic plant remains are revealing how GunaiKurnai ancestors used Cloggs Cave for ritual practices over thousands of years. People deliberately gathered whole grasses, carried them into the dark cave, and burned them in thin layers, leaving behind…
Scientists discover a major brain shift between ages 50 and 75
Scientists have uncovered sweeping changes in how the human brain controls and organizes its genome beginning in midlife, offering new clues to why aging sharply increases the risk of Alzheimer’s and other neurodegenerative diseases. One of the biggest…
UV light reveals possible camouflage on a 125-million-year-old crocodile
A 125-million-year-old crocodile fossil has revealed preserved skin, possible sensory organs, sophisticated respiratory structures, and an unexpected pattern on its tail. Ultraviolet light exposed alternating bands that may represent ancient camouflage…
The shape behind the Einstein problem just revealed strange new physics
A mathematical shape famous for covering a surface without ever repeating has revealed an unexpected ability to twist light into unusual chiral patterns. The discovery could lead to new ways of controlling light, polarization, and advanced optical devi…
Supermassive black hole winds are 100 times more powerful than scientists thought
Astronomers have discovered that winds from a supermassive black hole are about 100 times more powerful than previously thought. XRISM observations showed the resulting turbulence spreading roughly 300,000 light-years, extending far beyond the black ho…
The U.S. Eradicated this flesh-eating parasite. Now it’s back
The flesh eating New World screwworm has returned to the United States, threatening livestock, wildlife, pets and potentially people as it spreads north. A new UC San Diego tracking system aims to predict where the parasite could strike next while offi…

Nearly 10,000 patients reveal what works best for knee arthritis pain relief
A major analysis of 139 clinical trials involving nearly 10,000 people suggests that some of the simplest treatments may work best for knee osteoarthritis. Knee braces ranked highest overall for reducing pain, stiffness, and mobility problems, while wa…
Tiny cell “antennas” may help explain why some babies are born with heart defects
A newly discovered communication system in the microscopic “antennae” of cells may help explain how some congenital heart defects develop. When genetic mutations disrupt this system, the effects may extend beyond the heart to organs including the brain…
Plague was killing entire families thousands of years before the Black Death
Ancient DNA reveals that plague was already killing hunter-gatherers in Siberia 5,500 years ago, long before cities and flea-driven epidemics. The prehistoric strains may have been especially dangerous because they carried a genetic factor capable of p…
A coral reef thought dead for 60 years is teeming with life
More than 60 years after surveys suggested a deep coral reef off Benin was probably dead, scientists have found it alive. Cameras revealed healthy-looking coral patches supporting multiple fish species more than 50 meters beneath the surface. The disco…
