Bubbles has…

Scientists develop new method for deciphering ancient scrolls

Even a handheld XRF scanner is sufficient to determine most promising scrolls for further analysis. The Vesuvius Challenge is an ongoing project that combines “digital unwrapping” with crowdsourced machine learning to decipher the so-called Herculaneum scrolls, badly charred 2,000-year-old papyri too fragile to be physically unrolled. The effort just…

What happens when neutrinos swap identities inside a supernova?

Identity-fluid particles may carry some energy out, leading to direct collapse. Our basic understanding of core-collapse supernovae hasn’t changed in decades. Large stars burn through all the fuel at their cores and start creating heavier elements in reactions that consume energy. The lack of energy from these reactions allows…

How chimps teach their kids tool tricks

Adults first demonstrate tool use, then hand over the implements to their infants, who copy the behavior. Chimpanzees are known to use rudimentary tools when foraging for food. According to a new paper in the journal Frontiers in Psychology, this learned behavior is passed down from adults to offspring…

Trump EPA moves to wipe out climate rules for power plants

EPA says power plant emissions have no material impact on climate change. On the heels of the hottest summer on record and a United Nations report warning that global temperatures are likely to push climate risks to “increasingly dangerous heights,” the Trump administration overturned most of a Biden-era rule…

A new solar cell could generate electricity underwater

The trick isn’t using perovskites—the trick is making them last. In one episode of the Hanna-Barbera cartoon Birdman, the eponymous hero struggles to fight the evil Dr. Shark aboard a submarine without solar energy to recharge his powers. So Birdman would surely appreciate the new perovskite solar cells developed…
