NYT: a new form of ice?

Via the New York Times:
Shaken and chilled — but not stirred — ordinary frozen water turns into something different: a newly discovered form of ice made of a jumble of molecules with unique properties.

“This is completely unexpected and very surprising,” said Christoph Salzmann, a chemistry professor at University College London in England and an author of a paper published on Thursday in the journal Science that described the ice.

Water is a simple molecule that has been intently studied by scientists for centuries: two hydrogen atoms jutting off at a 104.5-degree angle in a V-shape from a central oxygen atom.

The new discovery shows, once again, that water, a molecule without which life is not known to be able to exist, is still hiding scientific surprises yet to be revealed. This experiment employed relatively simple, inexpensive equipment to reveal a form of ice that could exist elsewhere in the solar system and throughout the universe.

Ball milling ice - well, that's new!
