Water, the most familiar of substances, has long concealed a secret phase of existence — a glassy stillness that lies between liquid and ice, never before directly observed. An international research team has now witnessed this hidden transition by confining water within nanoscale lipid membranes, preventing crystallization and revealing that water can slip into a glassy state across a far wider temperature range than science had imagined. Published in Nature Communications and anchored by experiments at Australia's ANSTO research center, this discovery reframes our understanding of water not
