Alex Goldmark, the Senior Producer on the night duty here.

Well, after a little investigating we're changing our changes. The producer we put on the explosion story out of Connecticut reported back that there don't seem to be all that many incidents involving natural gas plants and safety issues. We didn't want to treat this like shark attacks where we make a bigger deal out of a high profile incident and create the impression there is a trend or persistent danger worthy of panic.

So instead, we're talking about what we do think is a potential real danger (though on a much longer time horizon). Tomorrow we'll try to evaluate the scope and trajectory of Iranian nuclear ambitions. Are sanctions the answer? Is engagement? And how far along is Iran really? 

Our Washington Correspondent Todd Zwillich will also bring us a radio obituary of John Murtha, including a list of all the public buildings already named after the Democratic Congressman in his district. It's way way more than you'd expect. 

UPDATED 4:15 p.m.

We added another topic for tomorrow: After an explosion at a Connecticut power plant killed five people over the weekend, we're going to delve deeper into the link between safety issues and the increased demand for natural gas.

Jim (the web editor here) with a quick update on tomorrow's show.

The Obama administration is trying to get the nation's students on a good diet. Later today, officials will announce a new law that would expel junk food from school vending machines. For tomorrow's show, we're reaching out to schools that found successful ways to get their students on a nutritious diet.

We'll also check in on another development in the Haiti recovery: The country's radio stations are finally getting back on the air. We'll find out how that's helping Haitians get back on their feet in a country that has historically relied on radio as a medium for civic engagement.

And our weekly conversation about the workplace has a Valentine's theme. Beth Kobliner will tell us how people navigate (or fail to navigate) the fraught world of office romances. Have you ever had to manage a romance in the workplace? Let us know!
