Dolphins are washing ashore in alarming numbers in the Mid-Atlantic states this summer. More than 160 deaths of dolphins have been reported since early July and that's the worst fate in 26 years. Response teams from New York to Virginia are trying to determine just what's killing all these dolphins.

DAVE PREBECK: Geocaching is basically a high tech scavenger hunt.
SIMON: That's Dave Prebeck, president of NOVAGO, the Northern Virginia Geocaching organization.

Hundred dollar bills don't stretch as far as they used to. They're also getting a little frazzled. New 100 dollar bills were supposed to replace them over two years ago, but the Federal Reserve pushed back the date in 2010 because of a printing error.
This week, U.S. Attorney General Eric Holder proposed reducing mandatory minimum sentences for some drug offenders. Federal mandated drug-sentencing guidelines have been around since the 1980s and they are thought to contribute to the huge increase in the number of inmates in U.S. prisons.

Few American mothers could fathom a situation that would force them to leave their country in order to put food in their children's bellies, clothes on their backs and send them to school. This is the reality for many Filipina women, who cross oceans in search of jobs that pay enough to provide for their families back home.

Immigrant and farm worker rights groups came from Los Angeles to Bakersfield, Calif., by the busload this week. Bakersfield, in the state's Central Valley, is farm country, and immigration is a complex issue here.

Activists across the country are targeting a number of Republican members of Congress this summer, trying to pressure the House to take up the immigration reform bill passed in the Senate.
A new pipeline between the Central Asian republics of Kyrgyzstan and Kazakhstan was until recently pumping away. Not oil, though — moonshine.

New Jersey Gov. Chris Christie agreed to ease restrictions on medical marijuana for chronically ill children, but he won't go as far as lawmakers would like.
NPR's Joel Rose reports that Christie, a Republican, has rejected part of a bill that would allow young patients access to an ingestible form of marijuana at state-approved dispensaries without the approval of a psychiatrist and pediatrician.
His partial veto sends the bill back to the Democratic-controlled Legislature for approval before it becomes law.
In the digital world, almost everything you do to communicate leaves a trace. Often, emails are stored on servers even after they're deleted. Phone calls create logs detailing which numbers connected, when and for how long. Your mobile phone can create a record of where you are.
If you're a journalist trying to protect a confidential source, this is a very difficult world to work in.
Ancient North Americans gouged elaborate rock art into a heap of big boulders northeast of Reno, Nev., more than 10,000 years ago and perhaps 15,000 years ago.
