Protein traffic jams may explain aging, memory loss, and Alzheimer’s
Scientists at Stanford may have uncovered a hidden reason our brains decline with age. Studying the ultra-short-lived turquoise killifish, researchers discovered that the cellular machinery responsible for building proteins begins to jam and malfunction over time. Tiny

Astronomers finally solve Saturn’s decades-long spin mystery
A decades-old mystery about Saturn has finally been solved thanks to the James Webb Space Telescope. Scientists discovered that Saturn’s changing “rotation rate” was never caused by the planet speeding up or slowing down, but by powerful winds high in its atmosphere. Webb’s

This bizarre crocodile relative from the Triassic looked like an ostrich dinosaur
Scientists have discovered Labrujasuchus expectatus, a bizarre crocodile relative that looked more like an ostrich-like dinosaur than anything resembling a modern crocodile. It walked on two legs, had tiny arms, and sported a toothless beak—an unexpected combination for a
This newly discovered raptor may have hunted like a giant heron
A newly discovered raptor-like dinosaur from Patagonia is changing how scientists think about ancient predators. Named Kank australis, the 70-million-year-old dinosaur appears to have hunted fish much like modern herons, using a long, flexible neck and specialized vertebrae

Rogue planet moons could harbor alien life for billions of years
Scientists say moons around rogue planets wandering through the galaxy could remain warm enough for life thanks to tidal heating and hydrogen-rich atmospheres. These dark, starless worlds may have had stable oceans for billions of years — long enough for complex life to
Glaciers in the 'roof of the world' have suddenly started melting

Vitamin B12 and folate deficiencies linked to chronic fatigue
Feeling constantly drained might not just be about poor sleep or working too hard. Researchers in Japan found that low levels of key vitamins — especially vitamin B12 and folate — may quietly contribute to fatigue and lack of motivation, even in otherwise healthy people.
Human organoids reveal how to reverse “irreversible” nerve damage
Cambridge researchers created miniature brain-and-spinal-cord systems in the lab that can send signals and even trigger tiny muscle contractions. They discovered that human neurons gradually lose their ability to regrow after damage during development — but that ability can
CBD may slow Alzheimer’s by calming the brain’s immune system
CBD may be doing far more than just easing pain or anxiety — new research suggests it could help fight Alzheimer’s disease by calming the brain’s runaway immune response. In experiments using Alzheimer’s mice, scientists found that inhaled CBD reduced key drivers of

Chemical bonding is one of the central organizing principles of the microscopic world. It determines how atoms combine and thereby governs a wide range of physical and chemical properties of quantum systems across many length scales, ranging from small molecules and
Shock waves show how baby stars' cradles get their radial shape in 3D simulations
The universe is full of fascinating structures, and some of the most striking take shape inside the giant clouds where stars are born. There, streams of gas appear to converge from all directions toward a dense central hub, like spokes meeting at the center of a wheel.
Ammonia levels in urine could serve as marker for chronic kidney disease in dogs
Dogs with lower urine ammonia-to-creatinine ratios (UACR) may suffer from faster progression of kidney disease and higher fatality rates, according to new research from North Carolina State University. The work suggests that UACR levels may be a useful marker for identifying
