One story that's simmering at the Olympics in Rio de Janeiro has to do with sex: in particular, the controversy over intersex athletes, who are anatomically and genetically ambiguous.

At issue: Is it fair to allow those athletes, who often have high levels of testosterone, to compete with women?

Much of the attention has focused on South African runner Caster Semenya, the favorite to win gold in the women's 800 meters on Saturday. Semenya has been identified as intersex in many media reports, though she has never confirmed that or spoken about it.

At the Rio Olympics, there are the usual powerhouses:

Team USA, with 554 athletes. Australia, with 420. China, with 401.

And then there are the tiny countries: overwhelmed, but proud.

I went on a quest to find the tiniest of the tiny countries at the Summer Games. And I happened to find the delegation at the Olympic athletes' village, speaking a mashup of English and Nauruan.

They come from Syria, South Sudan, Ethiopia and the Democratic Republic of the Congo.

Ten athletes who are refugees are competing on the first-ever Refugee Olympic Team at the Rio Games. They are representing the estimated 65 million people around the world who have been driven from their homes.

With six years of Olympic preparation behind him, American Jason Pryor took to the fencing strip in Rio on Tuesday.

When I caught up with him a few days before his match, he told me, "I've never been more ready for anything in my entire life."

Pryor, 28, from South Euclid, Ohio, is the top men's epee fencer in the U.S., and ranked no. 24 in the world.

His opening opponent is Benjamin Steffen of Switzerland, ranked no. 13.

There are still nearly two more weeks of events at the Rio Olympics. In fact, some sports haven't even begun competition yet — track and field, badminton and taekwondo among them.

But for a couple of hundred athletes in a few sports, their games are already over. Their events were held, start to finish, this past weekend.

We are just a couple of hours away from the opening ceremonies at the Summer Olympics in Rio de Janeiro. Organizers say to expect lots of samba, of course, and a lot more. NPR's Melissa Block is in Rio and is with us now. Hey, Melissa.

When Haley Anderson competes at the Rio Olympics on Aug. 15, she'll be racing for about two hours in open water off Copacabana Beach. The marathon swim is not for the faint of heart. It's 10 kilometers, or 6.2 miles.

What does it take? "A certain kind of crazy," Anderson said with a grin. "You have to be a little weird to wanna put yourself through two hours or more of pain."

Two new flags will be flying high at the Olympic Games in Rio.

For the first time, South Sudan and Kosovo have been recognized by the International Olympic Committee.

South Sudan has three runners to its first Olympic Games. Kosovo, which was a province of the former Yugoslavia, will have eight athletes competing.

It is the world's fastest racquet sport, with speeds up to 250 miles per hour off the racquet.

And it may be one of the most misunderstood.

Badminton — that staple of backyard picnics and summer camp — becomes, at the expert level, a sport that requires lightning-quick reflexes, explosive power, stamina and agility.

Mix swimming and basketball with soccer, toss in some wrestling for good measure, and you have a pretty good description of the exciting, fast-paced sport of water polo.

The U.S. women's water polo team is ranked No. 1 in the world and is considered the favorite to bring home the gold medal at the Rio Olympics.

Since women's water polo became an Olympic sport in 2000, the U.S. women have medaled every time, and they won their first gold in London four years ago.

Editor's Note: Sharon Day-Monroe finished fourth in the heptathlon at the U.S. Olympic Trials on Sunday, July 10, in Eugene, Ore., narrowly missing the Olympic team. Only the top three finishers qualified.

Sharon Day-Monroe has been to the Olympics twice, in two different events. She's been the U.S. heptathlon champion three times. And she won four consecutive U.S. indoor pentathlon titles.

It's a hugely impressive resume. But at 31, she knows this may be her last shot at Olympic glory.

Editor's Note: Vashti Cunningham made the U.S. Olympic team by finishing second in the high jump at the U.S. Olympic Trials in Eugene, Ore., on July 3, clearing 6-foot-5 (1.97 meters). Her brother Randall Cunningham Jr. did not make the team.

Tucked amid the tumult of Lower Manhattan's Financial District, right across from a factory-outlet shoe store promising "probably" the lowest prices in the city, you'll find Alexander Hamilton's grave. With the explosive popularity of the Broadway musical Hamilton, that grave is seeing a surge of new fans coming to pay respects to the Founding Father.

Lillian Hasko has seen the musical twice, bought the soundtrack, and felt compelled to make the pilgrimage downtown.

Guy Clark, one of Nashville's most renowned singer-songwriters, has died at the age of 74. This profile of Clark originally aired on July 23, 2013, on All Things Considered.
