In 1998, when Pope John Paul II made his historic visit to Cuba, few Cuban-Americans made the pilgrimage across the Florida straits.
But when Pope Benedict XVI arrives in Cuba on Monday, hundreds of Cuban-Americans will be on hand in Santiago de Cuba when he celebrates Mass.
Carlos Saladrigas is well-known in Miami's Cuban-American community. He's a prominent businessman and co-chairman of the Cuba Study Group, an organization working to make Cuba a free and open society. He'll be in Antonio Maceo Revolution Square for Mass.
Former Vice President Dick Cheney is recovering from a heart transplant he received Saturday at Inova Fairfax Hospital in Falls Church, Va.
The operation makes Cheney among more than 2,300 Americans who get heart transplants every year.
Heart transplantation has come a long way since Christiaan Barnard stitched the heart of a young woman into the chest of a middle-aged man in South Africa in 1967. That transplant recipient died 18 days later. Today, recipients can expect to get a decade or more of life from their new hearts.
In June of 2009, a committee met at the University of Wisconsin-Madison to do a routine safety review of proposed research projects.
One of those projects involved genetically modifying flu viruses. And during the review, the committee brought up the idea of "dual-use" research. "Dual use" means legitimate scientific work that's intended to advance science or medicine, but that also might be misused with the intent to do harm.
When the U.S. Supreme Court hears challenges to the Obama administration's health care law this week, the arguments will be complex, with questions about states' rights, mandatory insurance, and Medicaid.
To introduce those concepts — and to give the rest of us something to do while the court hears six hours of arguments — we offer a word search game. The grid below features many words you'll likely hear this week, as NPR's Nina Totenberg reports from the court.
It's the hottest ticket in Washington, D.C. Even the flossiest lawyers in town can't get a seat. Senators, congressmen, Cabinet and White House officials are all vying for a place.
At the U.S. Supreme Court, people have been lining up for days, waiting to hear this week's historic oral arguments on President Obama's health care law. The arguments will last for six hours over a three-day period, the longest argument in more than 40 years.
Researchers haven't given much thought to the effect of noise and noise pollution on plants. After all, plants don't have ears — at least, not the kind you hear with — so there doesn't seem to be much point. But thanks to ecologist Clinton Francis, that could be about to change.
Francis is a postdoctoral researcher at the National Evolutionary Synthesis Center in North Carolina. But he has spent the past few years in northwestern New Mexico, studying noise pollution in Rattlesnake Canyon.
Posting on Facebook is an easy way to connect with people, but it also can be a means to alienate them. That can be particularly troublesome for those with low self-esteem.
People with poor self-image tend to view the glass as half empty. They complain a bit more than everyone else, and they often share their negative views and feelings when face to face with friends and acquaintances.
Free health clinics have long been places people turn to when they don't have health insurance or any money to pay for care. But the health law's expansion of coverage puts free clinics in uncharted territory.
While the law goes before the Supreme Court this week, health providers are already gearing up for a surge in patients with insurance.
Around the country, hundreds of free clinics have been established over the past 50 years to treat patients like Patsy Duarte.
The hooded sweatshirt has become an unlikely but potent symbol since the shooting of Trayvon Martin. Fox's Geraldo Riviera went so far as to say that wearing a hoodie might have contributed to Trayvon's death last month. But for the organizer of the "million hoodie march" in New York, and for many young black men in Florida, wearing a hooded sweatshirt has become a form of protest against racial profiling in the wake of Trayvon's shooting. NPR's Joel Rose reports.
