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.
