A mysterious spike of platinum buried deep in Greenland's ice has long fueled theories of a catastrophic comet or asteroid strike 12,800 years ago--possibly triggering a sudden return to icy conditions known as the Younger Dryas. But new research ...

A nearby galaxy is behaving strangely--and now scientists know why. The Small Magellanic Cloud's stars move in chaotic patterns because it slammed into its larger neighbor millions of years ago. That collision disrupted its structure and even created ...

Researchers have created a cutting-edge catalyst that turns CO2 into methanol more efficiently than ever before. Instead of using clumps of metal atoms, they engineered a system where each single indium atom actively drives the reaction. This ...

A new subatomic particle known as the cc has been discovered at CERN's Large Hadron Collider. This heavy proton-like particle contains two charm quarks and was detected using the upgraded LHCb experiment. Scientists observed it through its decay into ...

AI's growing energy use sounds alarming, but its global climate impact may be far smaller than expected. Researchers found that while AI consumes huge amounts of electricity, it barely moves the needle on overall emissions. The real impact is more .. ...

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 ...
