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.

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.
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.

Several states have passed what are known as parent-trigger laws, which give parents a path to make operational changes in failing schools. Education Week reporter Sean Cavanagh talks about where parent-trigger laws are in place and what we know about whether or not they are working.

Israel's government effectively rejects a "two-state solution" to its impasse with Palestinians and instead continues to wage a "campaign of ethnic cleansing" in the territories where his people live, Palestinian Authority President Mahmoud Abbas told delegates to the United Nations this afternoon.
