NASA's Curiosity rover has found definitive proof that water once ran across the surface of Mars, the agency announced today. NASA scientists say new photos from the rover show rocks that were smoothed and rounded by water. The rocks are in a large canyon and nearby channels that were cut by flowing water, making up an alluvial fan.
"You had water transporting these gravels to the downslope of the fan," NASA researchers say. The gravel then formed into a conglomerate rock, which was in turn likely covered before being exposed again.
One night in 1984, British scientist Frances Ashcroft was studying electricity in the body and discovered the protein that causes neonatal diabetes. She says she felt so "over the moon" that she couldn't sleep.
By the next morning, she says, she thought it was a mistake.
But luckily, that feeling was wrong, and Ashcroft's revelation led to a medical breakthrough decades later, which now enables people born with diabetes to take pills instead of injecting insulin.
