Teen pregnancies fell again last year, to another historic low, a government report shows. "The continued decline is really quite amazing," said Brady Hamilton, the lead author of the new report from the Centers for Disease Control and Prevention. Last year, the birth rate for U.S. teens dropped 8 percent. Rates have been falling since 1991, and this marks yet another new low. (6/2)

Concussions have become part of the daily news. But how much have these brain injuries become part of daily life? To find out, we asked people across the country about concussions in the latest NPR-Truven Health Analytics Health Poll. The poll, conducted during the first half of March, found that nearly a quarter of people — 23 percent of those surveyed — said they had suffered a concussion at some point in their lives. Among those who said they'd had a concussion, more than three-quarters had sought medical treatment. (Hensley, 5/31)
