For over a century, water’s strange behavior—like expanding when it freezes—has puzzled scientists. Now, researchers at Stockholm University have used ultra-fast X-ray lasers to find the source: a hidden “critical point” in supercooled water. The discovery, published in Science, confirms that water exists in two competing liquid states, finally explaining its unique properties.
