Andy Soule, a U.S. Army veteran, lost both his legs to a bomb in Afghanistan in 2005. Four years ago, he won America's first medal — Olympic or Paralympic — in the biathlon event.

Dan Cnossen led a Navy SEAL team before losing his legs to a bomb in Afghanistan in 2009. After his injury, he began running on prosthetic blades, then tried skiing — and he's now in Sochi.

Performance under stress is something Dan Cnossen learned as a Navy SEAL. Now he's trying to use that skill as a biathlete, to ski his fastest right up to the target range and then quickly calm down enough to shoot with precision.
Biathlon may be the toughest endurance sport in the Olympics. After grueling circuits of Nordic skiing, athletes have to calm their breathing, steady their tired legs and shoot tiny targets with a rifle.
Andy Soule does it all with only his arms.
"It's a steep learning curve, learning to sit-ski," says Soule, a member of the U.S. Paralympic team. He's strapped into a seat attached to two fixed cross-country skis. He speeds along the course by hauling himself with ski poles.
There's a lot of talk about virtual currencies lately — how they work, economic implications and whether they're safe. But now a Native American tribe is using a bitcoin-like currency to help strengthen its sovereignty.
In South Dakota, the Oglala Lakota Nation has become the first Native American tribe to launch its own form of virtual currency. Payu Harris, its creator, calls it mazacoin.
Retired baseball pitcher Tommy John, left, and Dr. Frank Jobe at the National Baseball Hall of Fame in July 2013. <a href="http://baseballhall.org/news/press-releases/baseball-hall-fame-recognize-feature-film-%2742%27-alongside-dr-frank-jobe-during">Jobe was honored</a> for the pioneering surgery he first performed on John's elbow in 1974.
His name is attached to a surgery that has saved many major league pitchers' careers.
But Tommy John knows that's an honor he came by thanks in large part to good luck.
"Fortunately for me, I was at the right place at the right time," he told All Things Considered host Melissa Block on Friday. "I happened to have one of the greatest surgeons of all time being the surgeon for the Los Angeles Dodgers."
