A hormone already known for curbing appetite and supporting weight loss may have a surprising second job: protecting the liver from inflammation and scarring. Researchers at McMaster University found that GDF15 activates a previously unknown ...
Scientists analyzing a 2,200-year-old Roman shipwreck found that its hull was coated with pine tar and, in one area, a mixture of tar and beeswax. Pollen trapped in those ancient coatings acted like a geographic fingerprint, revealing the landscapes ...
Two very different types of quantum particles may be able to form stable droplets that hold themselves together, challenging decades of conventional thinking. The prediction could soon be tested experimentally and may reveal an unexpectedly rich ...
For decades, scientists have puzzled over why certain atomic nuclei unexpectedly produce large numbers of low-energy gamma rays. A new experiment traced the effect to magnetic changes inside the nucleus, where protons and neutrons effectively flip ...
A colossal cliff system created as the supercontinent Rodinia broke apart may have exposed the heart of the Grand Canyon nearly a billion years before the Colorado River carved it. The ancient landscape could also help explain why enormous sections ...
Scientists have identified exceptionally rare soft tissue preserved in a 450-million-year-old crinoid fossil, more than 200 million years older than the first dinosaurs. Its delicate tube feet offer ...
Ozempic may work in the brain in almost the opposite way scientists expected, activating hunger-linked neurons that appear essential for sustaining fat loss. The surprising discovery in mice could reveal new targets for developing even more ...
Specialized brain scans reveal that schizophrenia is linked to widespread loss of the synapses that connect brain cells, with the left side of the brain hit especially hard. The damage follows a surprisingly organized pattern tied to the brain’s ...
The human family tree may be due for a major rewrite. Researchers argue that Australopithecus and Paranthropus should be folded into the genus Homo because new fossils have blurred many of the traits once used to separate them. The proposed shake-up ...
Extreme experiments have revealed how diamond behaves at crushing pressures beyond those inside Neptune and Uranus, resolving a decades-old conflict between theory and observation. The results could ...
A discarded SpaceX Falcon 9 stage crashed into the Moon on Aug. 5, leaving behind a newly formed crater about 60 feet wide. NASA’s Lunar Reconnaissance Orbiter captured detailed images showing bright and dark streaks of debris blasted across the ...
Spain’s total solar eclipse delivered an unexpected sight: a corona glowing gold instead of its usual pearly white. Because the Sun was setting, its light passed through more atmosphere, while smoke from nearby wildfires filtered out even more ...

AI may be able to predict how strongly someone will respond to a vaccine before they receive it. By analyzing antibody patterns in more than 4,000 people, researchers found signs of “immune ...

People who participated in colorectal cancer screening had a 43% lower risk of dying from the disease, according to long-term data from more than 376,000 people in Sweden. The findings suggest that ...

Knee osteoarthritis can seriously affect mobility and quality of life, but its progression isn’t completely out of your control. Exercise, stronger leg muscles, a healthier diet, and even modest ...

Scientists have found evidence that the effects of a mother’s age on her offspring may be driven by reversible changes in gene activity rather than permanent DNA damage. The discovery raises the ...

A few minutes of sprinting may reshape the bloodstream far more dramatically than a much longer moderate workout. Six 30-second sprints altered nearly a quarter of the blood proteins measured and ...

Physicists may have uncovered a hidden feature inside protons that helps preserve one of matter’s most fundamental properties. RHIC collision data suggest baryon number is carried not simply by ...

Nature invented biodegradable plastic long before humans did—and animals may have been feeding on it for hundreds of millions of years. Researchers discovered that dozens of animal species possess ...

Scientists have found that the AMOC may be far more vulnerable to rapid warming than to temperature alone. When warming happens slowly, the ocean can adapt, but at faster rates similar to today’s, ...

Scientists may have uncovered evidence that a mammal ancestor was giving birth to live young 236 million years ago. A fossilized cynodont showed a neonatal growth line and an unusually large birth ...

A protein inside appetite-controlling brain cells may play an important role in preventing overeating and obesity, particularly when high-fat foods are readily available. Unexpected differences ...

An eight-year Finnish study found that children who spent more time on screens tended to show better cognitive processing as teenagers, challenging common assumptions about screen use. Researchers ...

Scientists have discovered that tiny, sharply curved wrinkles in graphene can dramatically alter its electrical behavior, creating surprisingly strong charge separation. The finding suggests future ...

Simply choosing the stairs could have surprisingly big benefits for your heart and longevity. A large analysis involving more than 480,000 people found that regular stair climbers were 39% less ...

Women who used estrogen-only hormone therapy later in life were less likely to develop dementia and showed fewer signs of Alzheimer’s disease in their brains, according to a large study of more ...

Astronomers using the James Webb Space Telescope have discovered a bizarre object from just a few hundred million years after the Big Bang that looks like an enormous star but shines far too brightly ...

Physicists have found a new way to peer inside one of matter’s most elusive quantum states: the Wigner crystal, where electrons stop behaving like independent particles and organize into a ...

James Webb has captured a striking new infrared view of NGC 2392, the Lion Nebula, revealing the dramatic aftermath of a dying Sun-like star. At its center, a scorching white dwarf is blasting ...

Researchers have found a striking new way to potentially eliminate HIV soon after infection using a one-time combination of three therapies. In newborn nonhuman primates treated within three days of ...

The adult brain may be far better at repairing itself than scientists once believed. In mice, researchers discovered a special group of support cells called astrocytes that respond to damaged brain ...

Dogs may understand our emotions more deeply than scientists realized. Brain scans show that happy human faces activate regions in dogs linked to higher-level processing and reward, suggesting that ...
