Scientists uncovered a hidden “critical point” in water that may finally explain its bizarre, life-enabling behavior. Credit: POSTECH University, South Korea Researchers at Stockholm University have used advanced x-ray lasers to uncover a long-suspected feature of water: a critical point that appears when water is deeply supercooled. This occurs at about -63 °C and 1000 atmosphere. Even under everyday conditions, this hidden point influences how water behaves, helping explain many of its
