Scientists reveal the molecular dance of water

Water is familiar to everyone - it shapes our bodies and our planet. But despite this abundance, the molecular structure of water has remained a mystery, with the substance exhibiting many strange properties that are still poorly understood. Recent work, however, is shedding new light on water's molecular idiosyncrasies, offering insight into its strange bulk properties.
