ROBERT SIEGEL, HOST:
And I'm Robert Siegel. In Afghanistan today, a small breakthrough that may help avert a major crisis. U.S. and Afghan officials signed an agreement regarding the largest American-run prison in the country. This is the same prison where last month U.S. soldiers burned several copies of the Quran, setting off riots and reprisal attacks on Americans. NPR's Quil Lawrence reports from Kabul.
A U.S. soldier instructs Afghan soldiers in the western city of Herat last July. Afghans in security force uniforms have killed a number of U.S. and NATO troops recently. The shootings come as NATO works to prepare the Afghan forces to take control of security.
Army Capt. Joe Fritze (right), who trains Afghan police officers in Kabul, works closely with interpreter Gul Agha Shirazi. Fritze says he depends on Shirazi not just to translate, but to warn him if he senses anything suspicious or dangerous.
In Afghanistan, the killings are called "green on blue" — that's when an Afghan soldier or police officer turns his gun on a NATO ally.
There was a wave of such violence just last month after U.S. soldiers accidentally burned Korans. Over the next week, six Americans were killed, apparently at the hands of Afghans working with the U.S.
The top U.S. and NATO commanders in Afghanistan think they have some answers to this recurring problem, and it's up to U.S. soldiers like Capt. Joe Fritze to see if they work.
Meet Willow Tufano, age 14: Lady Gaga fan, animal lover, landlord.
In 2005, when Willow was 7, the housing market was booming. Home prices in some Florida neighborhoods nearly doubled from one month to the next. Her family moved into a big house; her mom became a real estate agent.
But as Willow moved from childhood to adolescence, the market turned, and the neighborhood emptied out. "Everyone is getting foreclosed on here," she says.
Reporting in Nature, researchers write they have deciphered the genetic code of the gorilla, the last of the great apes to have its genome sequenced. Study co-author Aylwyn Scally discusses what the data reveal about the evolution of humans and other apes.
The New Horizons Mission blasted off toward Pluto in 2006; it's on course to arrive in Pluto's neighborhood in 2015. Mission leader Alan Stern discusses the journey of the spacecraft, and why he thinks Pluto is still a planet. Plus, the mission to get Pluto on a commemorative stamp.
Reporting in Cell Metabolism, researchers write that when people who lead relatively sedentary lives worked out the DNA in their muscle fibers changed almost immediately. Scientists also found caffeine had the same effect on isolated rodent muscles. Study co-author Juleen Zierath discusses the DNA modifications.
