Saying it is deeply troubled by "tragic events" alleged to have happened at Penn State, the NCAA has told the school it is launching an examination of whether the university has "institutional control over its intercollegiate athletics program, as well as the actions, and inactions, of relevant ... personnel."

It's hard to miss the irony: Leon Panetta, as President Clinton's budget guru, backed billions of dollars in Pentagon cuts. Now, as secretary of defense, he's warning that the U.S. could become a "paper tiger" if his department's budget is further reduced.

On Thursday, the U.S. military successfully tested a new hypersonic missile. The missile flies at eight times the speed of sound with a range measured in the thousands of miles.

The Roman Catholic Church is about to buy a beacon of Protestant televangelism.

The Crystal Cathedral, a temple of glass in Garden Grove, Calif., will be sold to the Catholic Church for $57 million — a decision that left some congregants furious and their future up in the air.

When the Crystal Cathedral declared bankruptcy last year, it soon became clear the legendary building would have to be sold. There were several offers, but in the end, the church's board favored the Catholic diocese in Orange County.

Melissa Block talks with John Seabrook, staff writer at The New Yorker. His latest article, "Crunch," delves into the world of the SweeTango — a new hybrid apple that is part Honeycrisp, part Zestar. It's sweet and tangy. There's a hint of cinnamon, a hint of pineapple and a whole lot of crunch.

Scientists at the Italian Institute for Nuclear Physics are now touting a successful second experiment that may challenge Albert Einstein's long-held theory of relativity. The results show that neutrinos could travel faster than the speed of light. Guy Raz talks to Brian Greene, professor of physics and mathematics at Columbia University, about the findings.
