Squid Game Researchers are trying to endow human cells with the amazing camouflage and color-changing properties of squids' skin cells, reports Jennifer Ouellette for Ars Technica. Squids' chameleon-like abilities rely on their control over the microstructures that specialized cells in their skin create. In 2021, Viviane Callier wrote for Quanta about how living things often use diffraction to alter their colors. Slow Stability Last year, the mathematician Elena Giorgi posted a 900-page proof that slowly rotating black holes are stable. Rachel Crowell writes about the proof and Giorgi's broader research interests for Science News. In their proof, Giorgi and her colleagues considered what would happen if a rotating black hole were struck by gravitational waves. Steve Nadis explained their proof by contradiction for Quanta last August. | |
