Neanderthals did much more with wood than burning it. A new study of 597 wooden remains and footprints from Abric Romaní, a rock shelter in Capellades, near Barcelona, shows that weapons, tools and household items were made from it. They may have also built parts of their living space. The findings date from approximately 62,000 … Read more

Compared to the rest of the world, the American continent welcomed its first humans relatively late. You might think that this (relative) proximity to modern times should make it easier to study, but it seems the reality is not so simple. At least, that’s one conclusion of a recent review of genomic research on the … Read more
Biologist James D. Watson is famous for co-discovering the double helix structure of DNA. However, Watson appears to have greatly underestimated Rosalind Franklin’s contributions to the Nobel-winning discovery, which has not gone unnoticed by historians and scientists. But a new study offers unusual evidence, hidden between the lines of Franklin’s lab notes. Published in the … Read more
The Sun unleashed a powerful flare early on October 6, launching a coronal mass ejection (CME) toward Earth, and could give a boost to the northern lights later this week. NOAA’s Space Weather Prediction Center (SWPC) has issued a moderate geomagnetic storm (G2) watch for October 9, when the CME is expected to reach Earth. … Read more
For a long time, it was a truism in science that the human brain is born with all the neurons it will ever have. But platitudes can crumble, and this one seems unstable. The brain struggles to produce new neurons in people with depression A tantalizing body of evidence suggests that the human brain produces … Read more
Francis Halzen received the Nobel Prize in Physics on October 6 for his contributions to neutrino physics. Credit: Althea Dotzour/University of Wisconsin-Madison Belgian physicist Francis Halzen won the 2026 Nobel Prize in Physics for his work detecting elusive high-energy particles called neutrinos that come from deep space. The most unusual portrait of the Milky Way … Read more
Physicists have many interesting theories about how our universe might end up, including one that suggests it is not in its most stable state. If it goes to that state, we could all be plunged into quantum oblivion. Delicious, I know. But a new study suggests that this disturbing scenario may be less likely than … Read more
