ScienceNow: Researchers looking for better ways to make and store hydrogen have accidentally discovered an entirely new kind of ice. Made of molecular oxygen and hydrogen, the highly energetic and as-yet-unnamed compound currently exists only under rarefied laboratory conditions. It is different from the 17 known forms of ice, but researchers think its discovery could advance understanding of the nature of water under extreme conditions, such as in the interior of planets and even inside nuclear reactors. It also might help to spawn new rocket fuels.
The finding that the Saturnian moon may host layers of icy slush instead of a global ocean could change how planetary scientists think about other icy moons as well.
Modeling the shapes of tree branches, neurons, and blood vessels is a thorny problem, but researchers have just discovered that much of the math has already been done.
