Weekend Edition Sunday on NPR News

A dolphin being trained by the Navy to find underwater mines recently made a surprising discovery: a 130-year-old brass torpedo, lying dormant at the bottom of the ocean. Host Rachel Martin talks with Chris Harris, chief of operations for the Navy's Marine Mammal Program, about the find.

Host Rachel Martin speaks with John Janssen, who was a City Council member in Greensburg, Kan., when that small town was devastated by a tornado in 2007. He offers his advice for residents of Moore, Okla.

Host Rachel Martin gets the latest sports news from NPR's Mike Pesca. This week, they discuss a couple dubious baseball records.

Dr. Keith Layne's practice was destroyed in the tornado that hit Moore, Okla. Now the family practice doctor is scrambling to treat patients while worrying about their mental and physical health.

In the sixties, many of the women on television were cute, a little silly, and married. A couple shows even featured women who were sweetly supernatural - think Bewitched and I Dream of Jeannie.

There were countless sacrifices made during the Civil Rights movement, in Birmingham, Ala. And for African-American students graduating high school during a particularly turbulent year, one of those sacrifices was their prom.
