Kepler-51d is a giant, ultra-light "super-puff" planet wrapped in an unusually thick haze that's blocking scientists from seeing what it's made of. Observations from JWST revealed that this haze may be one of the largest ever detected, possibly ...

A new tomato-picking robot is learning to think before it acts. Instead of simply identifying ripe fruit, it predicts how easy each tomato will be to harvest and adjusts its approach accordingly. This smarter strategy boosted success rates to 81%, .. ...

MIT physicists have built a powerful new microscope that uses terahertz light to uncover hidden quantum motions inside superconductors. By compressing this normally unwieldy light into a tiny region, they were able to observe electrons moving ...

Researchers have pushed quantum chip design into a new era by simulating every physical detail before fabrication. Using a supercomputer with nearly 7,000 GPUs, they modeled how signals travel and interact inside an ultra-tiny chip. Unlike earlier . ...

A new study put ChatGPT to the test by asking it to judge whether hundreds of scientific hypotheses were true or false--and the results were far from reassuring. While the AI got it right about 80% of the time on the surface, its performance dropped ...

Early life stress may set the stage for long-term digestive problems by disrupting the gut-brain connection. Studies in both mice and thousands of children found links to symptoms like pain, constipation, and IBS. Scientists discovered that different ...

Bull sharks may have a reputation as lone hunters, but new research reveals they actually form social bonds and even have preferred "friends." After six years of observing 184 sharks in Fiji, scientists discovered these animals don't just mix ...

Astronomers have identified a strange new kind of exoplanet that challenges how scientists classify worlds beyond our Solar System. The planet, L 98-59 d, appears to contain a vast ocean of molten rock beneath its surface that traps large amounts of ...

A key Alzheimer's drug has finally revealed its secret. Researchers discovered that lecanemab works by activating the brain's immune cells--but only through a specific part of the antibody called the Fc fragment. This piece acts like a trigger, ...

A mysterious metal-rich asteroid called Psyche has been baffling scientists for over two centuries, and its true origin remains one of the biggest unanswered questions in planetary science. Is it the exposed core of a failed planet, or a chaotic mix ...
