Olympic sports are marvels of power and beauty. They're also marvels of physics. Take ski jumping. Skiers launch themselves into flight at speeds up to 60 miles per hour. They fly through the air for the length of a football field or more and land usually gracefully. We asked physics professor John Eric Goff, at Lynchburg College, to explain the physical forces at work in ski jumping. He wrote the book "Gold Medal Physics: The Science of Sports."
There's new evidence out today that's raising questions about whether women in their 40's and 50's should routinely undergo mammography to detect breast cancer. A new analysis of a big Canadian study found no evidence that regular mammograms save lives. The study even suggests that for many women, regular breast X-rays may do more harm than good.
NPR's Rob Stein joins us now to talk about this report. It appears in the British medical journal BMJ.
Some strategists still see a small window of opportunity to address climate change before the effects become damaging and costly. At least one economist, for example, says we can make a lot of progress if at least half the world agrees to put a price tag on the carbon we dump into the atmosphere.
But some big thinkers also see a grim, potentially dangerous world ahead — one where nations, confronting a climate crisis, will instead reach for a risky technological fix.
U.S. speedskating took a big hit in Sochi today, coming out of the 1,000-meter competition with no medals. The team's highest rank was eighth, earned by Shani Davis, who has dominated this race in the past.
Finally this hour, a new perspective on the enduring influence of The Beatles. It comes from another four-piece British rock band called Temples. The group is from the town of Kettering. Critics have been raving about them since last summer. Their debut album, "Sun Structures," has now been released here in the U.S. And hearing it might whisk you away to 1960s Liverpool. Here's our critic, Tom Moon.
TOM MOON, BYLINE: If nothing else, Temples has impeccable timing.
Lake Street Dive is powered by the voice of Rachael Price; it's what hits you first when you listen to this quartet. It's a ringingly clear, strong voice, a sound that's at once beseeching and in control. Price regularly harmonizes with the other members of Lake Street Dive — bassist Bridget Kearney, drummer Mike Calabrese and Mike Olson, who also plays guitar and trumpet. But most of the songs on Bad Self Portraits are showcases for Price's surging vocals.

The Capitol Hill crackdown on sexual assaults in the U.S. military has been a rare mission on which Republicans and Democrats have found common ground over the past year.
The effort, spearheaded by Senate women — including an unprecedented seven on the Armed Services Committee — has already resulted in scores of tough new provisions designed to root out sexual predators, improve victims' services, and end commanders' ability to overturn jury convictions.
