They have succeeded in directly observing the atomic arrangement of the inserted alkali metal...
AI masters task learning and sharing skills with other AI
Mar 18, 2024 (Nanowerk News) Performing a new task based solely on verbal or written instructions, and then describing it to others so that they can reproduce it, is a cornerstone of human communication that still resists artificial intelligence (AI). A team from the University of Geneva (UNIGE) has succeeded...
Mimicking exercise with a pill
Mar 18, 2024 (Nanowerk News) Doctors have long prescribed exercise to improve and protect health. In the future, a pill may offer some of the same benefits as exercise. Now, researchers report on new compounds that appear capable of mimicking the physical boost of working out — at least within...
