Science news: space, biology, climate, medicine and the research changing how we live.
Utrecht scientists tracked the colour of 15,000 fossil spores through four drill cores and found the plants that survived the mass extinction were the ones feeding the flames.
Georgia State researchers report that the oral antiviral GHP-88310 blocked transmission of a measles-like virus in ferrets when given shortly before or after exposure, and shortened illness in animals already infected.
Buck Institute researchers report that neurons carrying the rare APOE2 variant accumulate less DNA damage and resist cellular aging — and that adding APOE2 protein protected high-risk APOE4 neurons too.
Instead of forcing local ore to fit existing formulas, an Uppsala University team is cataloging everything inside Sweden's deposits at Kiruna, Bergslagen and Norra Kärr, then designing magnets to match.
A camera built to shoot the bright surface of Mars was pushed far beyond its design limits to capture a visitor from another star system, tail and all.
The 23-foot dinosaur, pieced together from more than 180 bone fragments in Gujarat, pushes the origins of a lineage that later produced titans like Brachiosaurus back by tens of millions of years.
Nine golden headbands and two mouthpieces from elite tombs — one still resting on the brow of a small child — show how island goldsmiths fused the styles of Egypt, Greece and the Near East.
A large BMJ study of people with type 2 diabetes found GLP-1 medications were associated with a notably greater risk of hair loss than rival drugs — though the shedding may be reversible.
A protein-based gel inspired by how enamel forms in infancy pulls minerals from saliva to rebuild the body's hardest tissue — something teeth cannot naturally repair once it is lost.
The largest genetic study ever of hyperemesis gravidarum points to appetite, nausea and metabolism pathways — and confirms a single hormone gene as the strongest culprit.
In a UCSF and Imperial College London trial, a single 25-milligram dose of the psychedelic triggered a surge in 'brain entropy' within an hour and left measurable changes detectable a full month later, hinting at how it may loosen rigid thinking.
Researchers found that influenza A deliberately breaks down structures called paraspeckles inside the nucleus, freeing proteins the virus appears to exploit to replicate — a discovery that could point to new antiviral drugs.
Boosting the protein in mice sharply reduced tau buildup and brain shrinkage, pointing to a possible new line of defense against Alzheimer's and related dementias.
A 38-foot Tyrannosaurus discovered on a South Dakota ranch shattered its estimate after a 10-minute bidding war — and reignited a fight between collectors and paleontologists.
In a small trial, a daily spermidine supplement reversed several markers of immune aging and strengthened antibody responses — especially in the people who needed it most.
Scientists sifting through two decades of stranding records discovered three never-before-seen strains of Helicobacter in the stomachs of pygmy sperm whales, tied to ulcers and gastric disease.
Sediment cores from Australia's K'gari reveal that some of its deepest freshwater lakes dried out about 7,500 years ago during a wetter-than-today era, a warning that even iconic waters aren't safe.
Scientists say tiny insect-eating creatures from Queensland's Riversleigh fossil beds belong to an entirely new marsupial order, Keeunamorphia, that thrived for 35 million years before vanishing.
Physicists at the University of Warwick identified a sudden turning point in the solar cycle that forecasts the strength of the next one, potentially giving satellite operators and power grids years of advance warning.
By jolting a mix of simple gases with 10,000 volts, a University of Sydney researcher brewed synthetic cosmic dust laced with the carbon-based molecules that form the building blocks of living things.
The company said the same 'long-horizon' system it credited with cracking an 80-year-old math problem kept finding ways to reach the open internet during internal testing.
A new study finds waters worldwide are being drained of oxygen by warming and pollution, threatening food webs and the planet's ability to regulate its own climate.
A new optical technique detects the loss of collagen's molecular chirality — an early warning sign of aging that appears before fibers visibly thin or break.
A computer analysis of sauropod thigh bones shows young Uberabatitan and Neuquensaurus could stand on their hind legs with surprisingly little strain.
Regulators approved Takeda's Qdenga for people aged 4 to 60 with no need for pre-vaccination testing, as the country moves to blunt one of the world's heaviest dengue burdens.
Genetic analysis of 144 people from one of prehistoric East Asia's largest settlements reveals a society organized around patrilineal clans — and mass burials of sacrificed men.
Samples from the Moon's far side show solar-wind particles struck it harder than the near side — because Earth's magnetic field slows the stream that reaches the hemisphere facing us.
The broad-spectrum filter, a staple in Europe for years, gives U.S. consumers stronger protection against the UVA rays tied to aging and skin cancer. Products are expected this fall.
Engineered bacteria embedded in the material digest it on command, breaking it fully into building blocks with no microplastics left behind.
Biogen's diranersen missed its main goal in a Phase 2 trial but reduced tau pathology and showed signs of slowing decline, enough to push it toward a Phase 3 study.
