AN EXOTIC form of water could be the key to storing hydrogen for use in fuel cells. Wendy Mao at Los Alamos National Laboratory in New Mexico and colleagues bombarded ice with X-rays for around 6 hours at extremely high pressures comparable to those at which diamond forms. To their surprise, the water molecules broke down into separate oxygen and hydrogen molecules, which then recombined to form a brownish, stable alloy (Science, vol 314, p 636). “This is a novel material, uniquely different from water,” says David Mao, a team member at the Carnegie Institution in Washington DC. “It is very energetic,
