The internet, libraries and bookshops are full of plans and advice on how to lose weight, from fad diets to intense exercise routines. But there could be another route to keeping the pounds away, and that's with a gut bacterium ...
At the 2024 International Mathematical Olympiad (IMO), one competitor did so well that it would have been awarded the Silver Prize, except for one thing: it was an AI system. This was the first time AI had achieved a medal-level ...
Robots could soon be able to autonomously complete search and rescue missions, inspections, complex maintenance operations and various other real-world tasks. To do this, however, they should be able to smoothly navigate ...
People can think, behave and function very differently. These observed differences are known to be the result of complex interactions between genetics, neurobiological processes and life experiences.
Harvard Medical School researchers report that higher day-to-day "trigger surprisal" scores were associated with migraine attacks over the next 12 and 24 hours. In this cohort, higher surprisal scores aligned with greater ...
In a recent study, Dr. Weronika Tomczyk and her colleagues conducted a zooarchaeological and isotopic study of ancient Andean condor bones from an archaeological site Castillo de Huarmey, providing the first and earliest ...
