These days, hotels aren't just looking to hire bellhops, concierges and housekeepers. What the industry really needs are digital bloodhounds: people who understand how to use new technologies to track — and attract — potential guests.

One of those newfangled workers is Greg Bodenlos. At 24, he's just a couple of years out of Cornell University's School of Hotel Administration. His official title is digital marketing strategist at The Mark Hotel, a luxury hotel in New York City.

A new romantic comedy opens in theaters this week, and it stars a scientist as the likeable, and only slightly nerdy, main character. The film's writer and director, former scientist Valerie Weiss discusses Losing Control, and why she made the shift from lab bench to big screen.

Intended for a clinical audience, Smith talks about the unexpected response he got from the public.

At age 11, actor Alan Alda asked his teacher what a flame was. He received a confusing answer: "oxidation."

The White House has made its choice for who should lead the World Bank. Jim Yong Kim is currently the president of Dartmouth University. He's a physician and a global health expert and something of a surprise to people who've been watching this process.

Here is President Obama at the White House this morning.

Next week, the Supreme Court will hear challenges to the health care law. Continuing Tell Me More's preview of the case, host Michel Martin sits down with Neal Katyal. He is former Acting Solicitor General and defended the Affordable Care Act in lower courts.

Nicholas Stoller made his directorial debut with the raunchy 2008 comedy Forgetting Sarah Marshall, which starred Jason Segel as a guy who had to reassess his life after his girlfriend of five years dumped him.

Segel famously dropped his towel in the opening scenes of the film, which led The New York Times to call him "a young actor with nothing to hide."
