Nanoscale confinement blocks ice, revealing water's glass transition

A team of international researchers has employed facilities at the Australian Nuclear Science and Technology Organisation (ANSTO) to reveal previously unknown properties of water, the most ubiquitous substance on Earth. Their results, published in *Nature Communications*, shed light on how water behaves at extremely low temperatures, a question that has long challenged scientists.

The study used advanced neutron scattering techniques to probe the structure and dynamics of water molecules under cryogenic conditions. By observing subtle changes in the arrangement of hydrogen bonds, the researchers identified a new phase transition that occurs when water is cooled below a critical temperature. The findings have immediate relevance to several applied fields: they improve models for cryopreservation of biological tissues, inform the design of more efficient food‑freezing processes, and enhance our understanding of water confined within the nanoscopic spaces of living cells.

These insights demonstrate how fundamental research can inform practical technologies that rely on precise control of water at low temperatures. The collaboration underscores the value of shared scientific infrastructure and the importance of studying water’s behavior in regimes that mimic real‑world applications.
