Alaska's glaciers respond to climate change by melting for three additional weeks with every 1 degree Celsius increase in the average summer temperature, data from satellite-mounted radars show.

With AI, it's now possible for researchers to predict the three-dimensional structures of proteins directly from their amino-acid sequences. But what biologists really want to predict, says Columbia biophysicist Hashim Al-Hashimi, ...

More and more people are turning to AI chatbots as if they were close friends—venting about personal struggles, asking for advice, and even sharing their deepest secrets. These conversations can feel strikingly real, with ...

The ALICE Collaboration takes a step further in addressing the question of whether a quark–gluon plasma can be formed in proton–proton and proton–nucleus collisions. In the first few microseconds after the Big Bang, ...

For millennia, sling bullets served as a hand-thrown projectile that could be used to fend off enemies. At Hippos, 70 sling bullets made of lead have been recovered over the course of fieldwork and excavation. However, while ...

Every time we do a load of laundry, tiny fibers of polyester escape from our clothes and slip down the drain. These microfibers, so small they can be invisible to the naked eye, are among the most common forms of microplastic ...

Chemists may soon have one less rigorous step to worry about when searching for the right molecules to accomplish their highly specific innovation needs. Scientists have now built a new machine learning model that can predict ...

Over the past decades, quantum scientists have introduced various technologies that operate leveraging quantum mechanical effects, including quantum sensors, computers and memory devices. Most of these technologies leverage ...

New observations by a team of US astronomers have cast fresh doubt on whether the lunar surface could host abundant water ice. Publishing their results in Science Advances, a team led by Shuai Li at the University of Hawaii ...

A new study has for the first time elucidated the gut-liver immune regulatory axis jointly maintained by intestinal commensal bacteria and the intestinal endocrine system, and uncovered the fundamental mechanism underlying ...

For half the world's population, the water in their drinking glasses comes from below them. Groundwater also supplies 40% of global irrigation projects. Alarmingly, more than a third of the planet's aquifers, or groundwater ...

A potentially huge underground reservoir of freshwater beneath the Great Salt Lake is coming into sharper focus with a new study that used airborne electromagnetic (AEM) surveys to X-ray geologic structures under Farmington ...
