About the cover
Water droplets cooling rapidly in vacuum are probed by an intense pulse from a femtosecond X-ray laser before they turn to ice, providing Jonas Sellberg et al. with unique structural information on the deeply supercooled liquid phase in the so-called ‘no-man’s land’, where water’s anomalous properties become strongly enhanced, but where ice forms too quickly for normal measurement techniques to cope. In a second paper Jeremy Palmer et al. explore water in this regime with advanced simulation methods, finding a phase transition between two structurally distinct liquids that could explain many water anomalies.
