Scientists have uncovered why two seemingly opposite ways of targeting the same brain receptor can both promote weight loss. In mice, activating the GIP receptor in the brainstem reduced appetite, ...
Scientists have discovered that the aging human brain may be far less isolated from the rest of the body than once believed. Stanford researchers found that large numbers of immune cells from the blood begin entering the brain as early as middle ...
Nuclear reactors may go dark, but their fuel continues producing a faint antineutrino “glow” long after shutdown. Researchers have now detected that residual signal for the first time, finding it ...
A surprising stress-related signal may help the brain repair itself after injury. Researchers found that myelin-producing precursor cells rapidly release the stress hormone CRH near damaged brain tissue, helping control how those cells mature and ...
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 than 21,000 participants. Hormone therapy use was ...
Researchers have found strong evidence that original collagen can survive inside dinosaur fossils for tens of millions of years, overturning a long-standing assumption about fossilization. The ...
JWST has uncovered surprising clues that Neptune’s strange inner moons may be the wreckage of an ancient cosmic catastrophe. Researchers detected clay-like minerals on Larissa, Galatea, and Neptune’s rings that form in the presence of liquid ...
Astronomers have released more than three million new spectra in a sweeping expansion that, for the first time, brings SDSS-V optical observations to the Southern Hemisphere. The data reveal ...
Researchers have discovered that a gene linked to congenital heart disease acts like an architect for the heart cell’s DNA. Losing just one copy of TBX5 can cause the genome’s carefully folded 3D structure to unravel, disrupting the genes needed ...
NASA’s Perseverance rover caught a striking first from Mars: Earth disappearing behind the tiny moon Phobos. Seen from nearly 195 million miles away, our planet was reduced to a single point of light before briefly vanishing behind Phobos. The ...
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 ...
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 size that closely match patterns seen in modern ...

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, ...

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 ...

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 ...

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 ...

A forgotten fragment of a lost papal letter is offering a surprising new explanation for the Norman Conquest. England may have backed the wrong pope during a bitter religious power struggle, giving ...

Marine heatwaves are emerging as a threat not just to coral reefs and fisheries, but to human health and well-being. Researchers warn that unusually hot oceans can fuel stronger storms, trigger ...

Dogs have been shaping—and being shaped by—humans for about 15,000 years, evolving from early partners of hunter-gatherers into an astonishing range of specialized companions. Across the globe, ...

Silver nanocatalysts have been found to switch where they perform their most important reactions depending on whether a solid oxide cell is making electricity or hydrogen. The discovery could enable ...

A new nanostructured carbon design lets fuel-cell catalysts use tiny amounts of platinum while remaining remarkably stable and efficient. The breakthrough could help hydrogen fuel cells become a more ...

Scientists have generated quantum entanglement directly from sunlight, potentially offering a lower-energy alternative to the lasers normally used in quantum technology. Their outdoor experiment ...

Genetic changes may set off a chain reaction that causes the spine’s natural shock absorbers to harden and deteriorate. Zebrafish with a faulty collagen-related gene developed mineral buildup and ...

Scientists probing life’s deepest origins have uncovered evidence that the first free-living cells may have emerged not once, but twice. The findings suggest a striking possibility: life may share ...

A total solar eclipse will plunge parts of Europe into darkness on August 12, 2026, with Spain offering some of the best views. ESA will livestream the spectacle from the Javalambre Observatory, ...

CT scans of the world’s rarest dodo skulls suggest the extinct bird may have had a stronger sense of smell, a highly sensitive beak, and a lifestyle that extended into dawn and dusk. The ...

Scientists have discovered incredibly tiny plasma whirlpools swirling across the Sun’s surface, some just 20 kilometers wide. These previously invisible vortices may twist magnetic fields and help ...

Dinosaurs conquered the land at enormous sizes, but strangely, they almost never evolved into truly tiny animals. New research suggests that physiology alone can’t explain this missing miniature ...

Tiny pollution particles from smoke, soot, and dust may worsen rheumatoid arthritis and raise the risk of painful flares, particularly after prolonged exposure. The findings suggest that avoiding ...

A prescription form of THC helped many people with PTSD escape recurring trauma-related nightmares, with more than one-third reporting that the nightmares disappeared completely after ten weeks. The ...
