The complex struggle at Japan's crippled Fukushima Dai-Ichi nuclear power plant continues. There's word this morning that even as they "used a milky bathwater dye" to try to trace the path of radiation-contaminated water that's getting into the ocean from the plant, workers are also deliberately dumping some other contaminated water into the sea because they need to drain the pools at the reactors in order to bring cooling systems back on line.

It's time to start worrying about what to wear to the prom, and website Fashism.com may have solved one source of teenage anxiety. It's offering a dibs system for prom dresses. A teenager can lay claim to her perfect gown on the site, which links to users' Facebook accounts. One of its founders told the Boston Herald she was inspired by personal experience. She was "absolutely mortified" at her own prom, when another girl wore the same dress.

Update at 1:45 p.m. ET. NPR's Eric Westervelt, who is in eastern Libya, has been in contact with Iman Bugaghis, a spokesman for the nascent rebel government. The opposition, Bugaghis says, rejects talk of any transition from Gadhafi to his sons:

"It's unacceptable. Of course. They (his sons) show that they have the same ugly face as their father. So I think nobody can argue with us about this. It is clear, it is obvious. ... It shows that that regime will not last forever. He is losing the support of his own sons."

A suicide bomber walked up to a bus stand in northwest Pakistan on Monday and blew himself up, killing at least six people a day after a blast killed dozens at one of the country's most important Sufi shrines.

Authorities said Monday's attack in the militancy-plagued district of Lower Dir was carried out by a bomber who appeared to be a young teenager. Sunday's suicide bombers who targeted the shrine in the Dera Ghazi Khan district of Punjab province were also described as young teens.

Saying that "we've always known that lasting change wouldn't come quickly or easily," President Obama kicked off his re-election bid this morning with an e-mail to supporters and a video.

There's also a message on his campaign Twitter page, saying that "today, we're filing papers to launch our 2012 campaign."

Here's the video.
