The endless debate over routine mammograms is getting another kick from an analysis that sharply questions whether the test really does what it's supposed to.
Dr. H. Gilbert Welch, coauthor of the analysis of mammography's impact, which was just published in The New England Journal of Medicine, tell Shots that the aim was to "get down to a very basic question."
Why people yawn is a mystery. But yawning starts in the womb.
Past studies have used ultrasound images to show fetuses yawning, but some scientists have argued that real yawns were getting confused with fetuses simply opening their mouths.
So Nadja Reissland, a researcher at the University of Durham in the United Kingdom, used a more detailed ultrasound technique to get images of fetal faces that could distinguish a true yawn from just an open mouth.
In the Gaza Strip fighting, where a cease-fire was reached Wednesday, the Israeli military pounded Gaza with hundreds of airstrikes. Hamas, the militant Palestinian group that rules Gaza, launched hundreds of rocket attacks on Israel.

The election may be over, but the bickering continues, and not just between NPR's Ron Elving and Ken Rudin. As President Obama defends his United Nations ambassador, Republicans on Capitol Hill continue to lambast her for "misleading" reports about what happened in the aftermath of the attack on the U.S. Consulate in Benghazi, Libya.

When his teenage son ventured into social media, Virginia father Mike Robinson wanted to make sure he could keep tabs on him. Robinson works in IT, so he rigged a surveillance system that works no matter what kind of device either of them is on.
"It's sort of like a version of remote desktop that enables you to run the program kind of silently in the background," Robinson says.
One day, checking in from his iPhone, Robinson discovered that his son had come across an adult meet-up site on Facebook.
David Knell was born on Nov. 23, 1916, in Youngstown, Ohio, the second son of immigrant families from Russia. Back then, Albert Einstein had just formulated his theory of relativity, the 40-hour workweek had just been created, and the hamburger had recently been invented.
We want to go now to a place where art and culture intersect. We've heard a lot about the shooting that took place at a Sikh temple in Wisconsin over the summer, and the questions and the soul-searching over that tragedy are still going on, both inside and outside the Sikh community. One man, though, says he has an idea to make the country a more tolerant place for Sikhs and everybody else, actually, and it comes in the form of comic strips.
