Maybe you've agreed to be an organ donor. There might be something on your driver's license — a red heart, a pink dot or the word "Donor" — to show it. That also means you've very likely agreed — even if you don't realize it — to donate more than just your organs.

I know that I'm an organ donor. I signed up years ago, when I renewed my driver's license. But I had no idea that I'd also signed up to donate my tissue. That is, until Laura Siminoff, a professor at Virginia Commonwealth University's medical school, explained it to me.

Yesterday the Food and Drug Administration gave the first green light on a drug to prevent HIV transmission.

Many experts say the drug will help hasten the end of the AIDS pandemic. But experts in Brazil say the drug alone isn't the answer.

One of the drug trials the FDA considered was done at the Oswaldo Cruz Foundation Research Institute, also known as Fiocruz, in Rio de Janeiro.

A Senate committee looked at the failure of HSBC bank to police money laundering.

Robert Siegel talks to Deborah Amos about heavy fighting that has broken out in the Syrian capital of Damascus. Government troops — reportedly backed by helicopter gunships — are battling rebels in at least four districts of the capital. Some Syrian activists say the 16 month uprising is reaching a tipping point.

In 2008, just a few days before the Democratic presidential primary between Barack Obama and Hillary Clinton in Pennsylvania, a large group of Pennsylvania voters got a very unusual phone call.

It was one of those get-out-the-vote reminder calls that people get every election cycle, but in addition to the bland exhortations about the importance of the election, potential voters were asked a series of carefully constructed questions:

Republican Mitt Romney's presidential campaign says a recently formed arm of the organization collected more than $10 million a week during a three-month period this spring. And most of the money care from high-end donors.

Romney Victory Inc., got its first four contributions on April 6 — three donations of $50,000 each and one check for $350. Since early April, it's pulled in $140 million.

The violence in Syria is increasingly being called a civil war, and it can also be called a sectarian war, because much of the fighting pits the majority Sunni Muslims against the minority Alawites who make up much of the country's leadership.

Yet not everyone fits neatly into a category. There are some Alawites who have joined the uprising.

One 30-year-old Alawite man, who doesn't want his name revealed, is nervous as he lights another cigarette and tells the story of how he came to side with the opposition and turned his back on the Alawite rulers.

The increasing debt load of college graduates has affected young people's lives in untold ways, from career choices to living arrangements. Now add another impact on a key part of young adult life: dating and marriage.

Rachel Bingham, an art teacher in Portland, Maine, learned this a few years back, when a guy broke it off after four months of a budding relationship. Among other reasons, he cited her $80,000 in student loan debt.

"He said it scared him," she recalls, "that it really made him anxious. And he just did not want to take on my responsibility."

As legal observers have sifted through the ashes and the tea leaves of the recent Supreme Court term, one justice has stood out for his dissents.

Justice Antonin Scalia was the first name on the joint dissent filed by four justices in the health care case. But it was Scalia's dissent in the Arizona immigration case, written for himself alone, that drew particular attention, and especially harsh criticism.

This past week, the National Oceanic and Atmospheric Administration (NOAA) released a report linking climate change to some of the extreme weather events of 2011, like the devastating drought in Texas and record high temperatures in Britain.

None of this bodes well for the future, but there is a glimmer of hope. It turns out that U.S. carbon emissions are down nearly 8 percent since 2006.

Although videos posted by Syrian activists show dozens of people buried in a mass grave in the village of Tremseh, Syria has rejected claims made by the United Nations that it used heavy weapons in the attack alleged to have taken place on Thursday. Weekends on All Things Considered host Guy Raz speaks with NPR's Deborah Amos who is watching the story from Turkey.
