Mammograms don't reduce the number of women dying from breast cancer, according to a large and long-term Canadian study. It's the latest chunk of data to raise questions in an increasingly partisan debate about the use of mammograms to screen for cancer.
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.
Rosa Finnegan celebrated her 102nd birthday on Wednesday. She was born in 1912 â€” the year the Titanic sank. She stopped working at 101 and now lives in a nursing home in Massachusetts. Time has gone by fast, she says.
Below are excerpts from Rosa's interview, reported and produced by Ari Daniel and Caitrin Lynch.
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."
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 â€” one where nations, confronting a climate crisis, will instead reach for a risky technological fix.

For many Americans it's been a harsh, disruptive winter, from the country's Northern edges to the Deep South.
When cold snaps and blizzards shutter schools, kids miss more than their daily lessons. Some miss out on the day's nutritious meal as well.
This recently became apparent to school administrators in rural Iowa, where extreme cold delayed openings two days in a row at Laurens-Marathon Community School, where 59 percent of students who eat school lunch qualify for free or reduced-price meals.
The numbers show Americans are getting more comfortable with online dating â€” a recent Pew survey found at least 11 percent of us have tried to find a match on the Internet. And the places to cyberdate are proliferating. No fewer than 1,500 dating sites are available in the U.S. to help singles connect, many for a fee.
But these days, we're not just online dating; we're niche online dating, with specific sites for singles of all stripes.
The dinosaurs were killed during the Fifth Extinction â€” which scientists suspect was caused by an asteroid. Now, we are living through an epoch that many scientists describe as the Sixth Extinction, and this time, human activity is the culprit. As one scientist put it: We're the asteroid.
Elizabeth Kolbert is the author of the new book The Sixth Extinction. It begins with a history of the "big five" extinctions of the past, and goes on to explain how human behavior is creating a sixth one â€” including our use of fossil fuels and the effects of climate change.

A Pennsylvania county judge has thrown out an assisted suicide case against a 58-year-old nurse named Barbara Mancini, who was accused of homicide last year for allegedly handing her 93-year-old father a bottle of morphine.
