This is SCIENCE FRIDAY, I'm Ira Flatow. Powerful storms this spring: tornadoes like the ones in Oklahoma have caused damage estimated in the billions of dollars and dozens of deaths.

When it comes to profound depression, many people just can't get relief from current treatments.
Now there's more evidence that the anesthetic ketamine, sometimes abused as a club drug, has potential as a fast-acting treatment for the condition.

The rival Koreas have not met face to face for such negotiations since February 2011.
