If you look up at the sky on a clear day, chances are you'll notice thin, white clouds—also known as contrails—following behind airplanes. The formation of these wispy ice clouds is a complex process ...

Scientists in Japan have used a global climate model to show that dust from land without snow cover in the Arctic is a major source of particles that form ice crystals in Arctic low-level clouds. This ...

Particular ice-nucleating proteins produced by certain bacteria have the ability to control the freezing point of water—so efficiently that no other known material can compete. An interdisciplinary ...

Ice-nucleating proteins order and freeze water at temperatures that would normally not allow ice formation. Researchers take clues from nature for cryopreservation, medicine, and anti-icing ...
