High school football players have changes in their brain function long before they have recognizable signs of a concussion, according to a new study.

The more hits a player got, the more brain function changed. The findings support the growing belief that a concussion comes as the result of a succession of insults, not just one bad hit.

The Fife and Drum Restaurant offers a daily lunch bargain that sounds hard to pass up: For just $3.21, you get a hot, tasty meal, made mostly from scratch and delivered to your table by friendly waiters.

NPR's Business News starts with a reversal from the Komen Foundation. The Susan G. Komen For The Cure Foundation has just announced that it will not pull its funding for Planned Parenthood after all. The breast cancer charity endured a massive backlash when it announced, earlier this week, it would no longer give Planned Parenthood money for breast cancer screening. NPR's Julie Rovner joins us to explain the turnaround. And Julie, what exactly did the Komen Foundation say this morning?

Saying officials have undertaken yet another campaign of "bullying and harassment" of its Persian service staff, the BBC called on the Iranian government to "repudiate the action of its officials."

In a blog post, the BBC's Director General Mark Thompson also called on the international community to "put maximum pressure on Iran to desist in this campaign of intimidation, persistent censorship and a disturbing abuse of power."

The Labor Department said the economy added 243,000 jobs in January, well beyond many economists' expectations. The unemployment rate fell to 8.3 percent.
