Researchers at Ruhr University Bochum, Germany, have shed light on the structure of supercritical water. In this state, which ...

High-pressure experiments generated the first direct observation of plastic ice, which has qualities of both crystalline ice and liquid water.

Water is an essential part of life on Earth, and possibly elsewhere – and now it we know it may have formed not long after ...
