Water’s ultimate freezing point just got lower

“Ice cold” just got even colder: By creating ice from tiny droplets only a few hundred molecules in size, researchers have pushed water’s freezing point lower than ever before and changed what we know about how ice forms.

Knowing how and why water transforms into ice is essential for understanding a wide range of natural processes. Climate fluctuations, cloud dynamics and the water cycle are all influenced by water-ice transformations, as are animals that live in freezing conditions.
