Using ultra-fast X-ray pulses at South Korean facilities, the team identified the state at about -63C and 1,000 atmospheres, with results published in Science.
The finding supports the theory that water has two liquid forms whose distinction disappears at a critical point, helping explain anomalies in density, compressibility, heat capacity and viscosity.
Researchers said the work could settle a debate lasting more than a century and guide future studies of water's role in physical, chemical, biological, geological and climate processes.

Beyond two liquids, does water form secret molecular shapes that control its power?

If water can be two different liquids at once, what does this mean for life on Earth?

A century-old water mystery is solved, but is the scientific debate truly over?

Could this breakthrough in water science finally make human cryopreservation a reality?
