At a time when astronomers around the world are reveling in new views of the distant cosmos, an experiment on the International Space Station has given Cornell researchers fresh insight into something...
While brooms and sponges are the means of choice to fight contamination in everyday life, cleaning sensitive surfaces such as electronic components requires different tools, including evaporation-base...
When you’re frying something in a skillet and some droplets of water fall into the pan, you may have noticed those droplets skittering around on top of the film of hot oil. Now, that seemingly trivial...

A new study has presented and characterized the formation and properties of a superparamagnetic ring, which fits snugly around a drop of water due to liquid-liquid interaction, and allows the drops to...
Experiments show that a collection of bouncing fluid droplets can behave like a microscopic system of spins — the intrinsic angular momenta of particles. This discovery could lead to a better understa...
Researchers film human viruses in liquid droplets at near-atomic detail
