One of the extraordinary scenarios dreamt up for AI is to will help governments make diplomatic and military decisions on the international stage. The thinking is that machines can process more information than humans on shorter time scales. And the possibility that geopolitical competitors might use AI to outmaneuver allies, increases the pressure to operate on the same terms.So an urgent and important goal is to understand the capability of AI systems in making these kinds of decisions.AI Warg ...read more

As the largest organ in the body, our skin protects us from UV radiation, chemical exposures, and pathogenic bacteria from the outside environment.The skin’s natural ability to make collagen slows down as we age. And the body needs various vitamins and healthy fats to keep functioning properly. While there’s no stopping natural aging completely, some supplements could help prolong and maintain skin health. Supplements can increase nutrients for the skin and sometimes do this from the insid ...read more

The James Webb Space Telescope (JWST) first imaged Supernova 1987A (SN) in September 2022. The image captured a mysterious dusty and gassy center that formed during the supernova’s explosion. The dust is so thick it shrouds near-infrared light. But, within the dusty center, a powerful hot neutron star may be lurking underneath, according to a new study published in Science.“It was so exciting looking at the JWST observations of SN 1987A for the first time. As we checked the MIRI and NIRSpec ...read more

For a while, experts assumed that our ancient human counterparts, the Neanderthals, were less advanced and intelligent than we were. But a study recently published in Science Advances is calling this long-held notion into question, reporting evidence of Neanderthals using adhesive material. That is to say, they were making glue.“Compound adhesives are considered to be among the first expressions of the modern cognitive processes that are still active today,” said Patrick Schmidt, who co-led ...read more

In 1997, when paleontologist Paul Sereno first began to unearth the remains of a dinosaur in Niger's Sahara Desert, he didn’t know what to think. He was excavating bones in a dry region called Gadoufaoua, which had a rich fossil bed first discovered by French uranium miners. There were a lot of light, aerated bones — usually associated with theropods, like Tyrannosaurus rex, and the birds that evolved from them — so the researchers assumed that was what they were dealing with.As Sereno beg ...read more
