Gifted dogs can categorize toys by function, not just appearance. In playful at-home tests, they linked labels like “fetch” and “pull” to toys—even ones they’d never seen before. The findings hint that dogs form mental concepts of objects, much like humans, pointing to deeper cognitive abilities. Gifted dogs can categorize toys by function, not just …

South African diamonds have revealed nickel-rich metallic inclusions, offering the first direct evidence of reactions predicted to occur deep in Earth’s mantle. The study shows how oxidized melts infiltrated reduced rocks, trapping both the cause and effect of diamond formation. These reactions help explain volatile-rich magmas like kimberlites, linking mantle chemistry to volcanic processes. Diamonds …

Researchers reviewing 46 studies found evidence linking prenatal acetaminophen (Tylenol) exposure with higher risks of autism and ADHD. The FDA has since urged caution, echoing scientists’ advice that the drug be used only at the lowest effective dose and shortest duration. While important for managing fever and pain in pregnancy, prolonged use may pose risks …

America already mines all the critical minerals it needs for energy, defense, and technology, but most are being wasted as mine tailings. Researchers discovered that minerals like cobalt, germanium, and rare earths are discarded in massive amounts, even though recovering just a fraction could eliminate U.S. dependence on imports. America already mines all the critical …
