How does blood doping boost performance in events like the Tour de France? Do anabolic steroids help the world's fastest man run faster? In his book, Run, Swim, Throw, Cheat , Chris Cooper discusses how these banned drugs work, or don't β and how they are detected.
The world record for high jump β the event in which a person hurdles himself over a horizontal bar β is just over 8 feet. That's like leaping over a stop sign, and clearing it by a foot. Jesus Dapena, of Indiana University, has studied the high jump for 30 years, filming athletes to understand exactly how they produce the force required to clear the bar.
Florida's Aquarius Reef Base is the only working undersea lab left today. But now that federal funds have dried up, it may be forced to surface. Oceanographer Sylvia Earle joins Science Friday from inside Aquarius, 60 feet underwater, to talk about sponges, corals and other life she's observed on the reef.
Antarctica has 90 percent of the world's ice--and it's melting. Ice sheet guru Bob Bindschadler talks about climate change in Antarctica, and rising sea levels across the globe. Plus, biologist Diana Wall talks about hidden life in the barren Dry Valleys, and microbe hunter John Priscu talks about "bugs in the ice."
ERIC MCCORMACK: (As Doctor Daniel Pierce) In this class, we're interested in what goes on in the brain. And if we were to put someone in an FMRI machine and watch what happens when they make up a lie, we'd see their dorsolateral prefrontal cortex light up like a Christmas tree...
MCCORMACK: (As Doctor Daniel Pierce) ...because we use our brains when we lie. We use our brains when we're being lied to. But can the brain ever lie to itself?
Engineers say technologies like spray-on clothing and 3D-printed shoes could help future Olympians break records. The Institution of Mechanical Engineers' Philippa Oldham discusses how technology impacts sporting performance and why engineers should work closely with regulators.
Tell Me More host Michel Martin and editor Ammad Omar dig through the listener feedback in Backtalk. This week they mark the end of "Linsanity" for fans of the New York Knicks, and the American Gaming Association weighs in on a story about casinos.
Not that you'd care, because you're dead, but how would you like it if the last thing you did on Earth was really, really embarrassing β like trying to gulp down a meal that's flip-flopping wildly in your mouth, tail out ...
... when along comes a mudslide, and boom! You and your lunch are frozen in place, harden into rock and then, a hundred or so million years later, there you are again, still gulping, but now under lights in a museum display case for an endless stream of strangers? Not good if you're a shy fish.
When Olympic swimmer Michael Phelps steps onto a starting block a few days from now, a Stanford scientist named Krishna Shenoy will be asking himself a question: "What's going on in Michael Phelps' brain?"
Specifically, Shenoy would like to know what's happening in an area called the premotor cortex. This area doesn't directly tell muscles what to do. But it's the place where the brain gears up for something the body is about to do, like swimming.

This week, a NASA satellite spotted a new iceberg broken from an ice sheet in Greenland known as the Petermann Glacier. The iceberg is twice the size of Manhattan, 46 square miles, and it's the second time in the last few years that an island sized chunk of ice has calved from the glacier.
