Monday's tornado in Moore, Okla., killed 24 people and caused an estimated $2.2 billion worth of damage. As the community reflects on what happened, one question is: How did so many managed to survive such devastating destruction?

Lifelong Oklahoman Kristi Freeman has seen her share of tornadoes, but she says the twister that tore through her neighborhood was something else.

"This tornado was like a monster. It was like something that was alive. It destroyed your peace, your comfort," she says.

As the 100th anniversary of Igor Stravinsky's ballet The Rite of Spring approaches, commentator Miles Hoffman reminds us that — as earthshaking as that infamous debut was — the composer soon branched out into a variety of musical styles that would surprise his fans and critics.

Everybody itches. Sometimes itch serves as a useful warning signal — there's a bug on your back! But sometimes itch arises for no apparent reason, and can be a torment.

Think of the itchy skin disorder eczema, or the constant itching caused by some cancers. "A very high percentage of people who're on dialysis for chronic kidney disease develop severe itch that's very difficult to manage," says Dr. Ethan Lerner, an associate professor of dermatology at Harvard Medical School.

Scientists now say they've got a much better clue as to how itch happens.

Unusually warm ocean temperatures and favorable wind patterns mean the Atlantic is likely to see "an active or extremely active" hurricane season this year, say officials from the National Oceanic and Atmospheric Administration.

The agency expects between seven and 11 hurricanes and as many as 20 named storms during the 2013 season, which runs from June 1 through November.
