NASA's Curiosity rover has found definitive proof that water once ran across the surface of Mars, the agency announced today.

The electronic circuits they're developing don't crash. It's more dramatic than that. They dissolve in liquid.

Sounds a little bit crazy, but circuits that work for a while then disappear could be pretty useful in medical devices implanted in the human body.
