TEDMED: Live from the Kennedy Center in Washington, D.C.
The phenomenon that is TEDMED has rolled into the nation's capital. And I'm camped out at the Kennedy Center for the nerdfest.
What's the big deal? I'm still trying to figure that out as the meeting is well into its second day. It's an event, that's for sure, and it's supposed to be a way for people who care a lot about health care to get together and make some headway on thorny problems.

Two U.S. Marines have been killed and two others injured when the V-22 Osprey they were in crashed Wednesday during a training exercise in Morocco.
NPR's Larry Abramson is reporting that the reservists were part of a Marine unit participating in the annual African Lion exercise with the Moroccan military. The two severely injured Marines are being treated in country.
More information about those killed and wounded will be released after the notification of next of kin.
The cause of the crash is still being investigated, but NPR's Abramson notes:
A retirement crisis is looming. As people live longer, one study finds that half of all households are at risk of coming up short on retirement money. And while many working households may feel they simply don't have enough to spare for retirement, experts say some of the biggest barriers to saving up are psychological.

Students wait to pass through a security checkpoint at the University of Pittsburgh's Cathedral of Learning on Tuesday. Security has tightened at the school after a string of false bomb threats on the campus.
Since mid-February, the University of Pittsburgh has received more than 50 bomb threats, and while they've all been false alarms, they have succeeded in disrupting campus life. Tighter security measures are now in place, but the threats continue, and students are wondering how they'll be able to make up class work and prepare for final exams.
A concert in Pyongyang in February 2012 commemorates the birthday of North Korea's late leader, Kim Jong Il. The backdrop shows a North Korean rocket that was launched in April 2009 — and was followed a month later by a nuclear test.
As North Korea reaches the final stage of preparations for a long-range rocket launch, concern is growing that it is in the early stages of preparing its underground test site for another nuclear explosion.
Pyongyang established the pattern three years ago when it tested a similar rocket and then followed it a month later with a nuclear test.
This time around, there may be a more urgent need to test a nuclear device. The bomb is very likely the result of a significant expansion of North Korea's nuclear weapons program.
President Obama has a chance to make fun of his opponents — and himself — when he addresses the annual White House Correspondents' Association gala later this month. Last year he joked about Donald Trump and the "birther" issue.
At the end of the month, President Obama will deliver a string of punch lines at the White House Correspondents' Dinner. It's an annual tradition, a chance for the man at the top of the pyramid to poke fun at his political opponents and himself.
Humor is an essential tool in any politician's kit — all the more so in an age of instant, constant media. It can disarm an opponent, woo a skeptical voter or pierce an argument. This year, both Obama and presumptive GOP nominee Mitt Romney are using it to try to win the upper hand in the presidential race.
