At cold temperatures, water has two different liquid phases, which become one at the critical point. The discovery could help ...

Researchers at Stockholm University have used ultra-short X-ray laser pulses at facilities in South Korea to identify a ...

New peer-reviewed experiments on supercooled water corroborate the transition between high- and low-density liquid states.

Supercooled water may be a two-for-one deal. A long-standing theory holds that liquid water at temperatures well below freezing is composed of two different arrangements of molecules, one with high ...
