Water Molecules (image) DOE/SLAC National Accelerator Laboratory Caption Water molecules, such as the one modeled at left, rapidly move toward a pyramidal structure, right, when supercooled. In a first-of-its-kind experiment at SLAC's Linac Coherent Light Source X-ray laser, scientists observed this accelerated transformation.
