At extremes, hot and cold act oddly alike
DUKE (US)—Observations suggest the superhot world shares similarities with the ultracold—a special kind of superfluidity where substances seem to move so effortlessly that nothing can stop them. Now theoretical physicists are using complicated mathematical tools to explain why. (more…)

High-speed images reveal essence of liquid
U. CHICAGO (US)—How do liquids behave when there’s a dramatic drop in surface tension—the physical property of liquid that allows droplets to form? For the first time, physicists have measured the nanoscale forces that cause droplet formation in a falling stream of tiny glass beads. (more…)
