Researchers uncover the mystery behind supercooled water's strange behavior

Normally, water turns to ice at 0°C, but if it is pure enough, it can remain liquid well below freezing—a state called 'supercooling.'

Scientists have long struggled to study this, especially in a temperature range called 'no man's land' between -40°C and -90°C.

For decades, experts suspected that supercooled water is actually a mixture of two distinct structural forms: a high-density liquid and a low-density liquid.

Researchers identified a 'critical point' at roughly -63°C, where these two phases interact, explaining why water behaves so differently from other substances.

This discovery is vital, as water’s unique properties, such as its expansion upon freezing, are essential for life.

By solving this mystery, scientists can better understand everything from climate patterns to how proteins function within our cells.
