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.
Full disclosure: The first thing I said when I saw that Rob Delaney would be talking to NPR's Audie Cornish on today's All Things Considered was that I was curious to see whether he had ever said anything on Twitter — where he has almost 670,000 followers (including me) as of this writing — that they thought they could read on the radio. It's an exaggeration. But not by that much.
An Israeli missile is launched from the Iron Dome defense system, designed to intercept incoming rockets. This missile was fired from the southern Israeli city of Ashdod in response to a rocket launched from the nearby Palestinian Gaza Strip on Nov. 18.
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 weeklong battle temporarily diverted attention from Iran, the archenemy of Israel and a key ally of Hamas. Israeli leaders have threatened to strike Iran over its nuclear program.
Yet the Gaza fight may offer insights into what a possible confrontation between Israel and Iran would look like.
Samuel Yirga is a pianist from Ethiopia. A 20-something prodigy, Yirga is too young to have experienced the Ethio-jazz movement of the early 1970s, but he has absorbed its music deeply — and plenty more as well. With his debut release, Guzo, or "Journey," Yirga both revives and updates Ethiopian jazz.

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. Plus: Mitt Romney's "gifts" that keep on giving. And Rep. Allen West concedes in Florida.
Composer Max Richter has done a brave thing for any artist in any medium: He's messed with a classic, specifically, Vivaldi's four violin concertos known as The Four Seasons. He has a new album simply titled Recomposed by Max Richter: Vivaldi, The Four Seasons.
Richter says that as a child, he loved The Four Seasons. But as he grew older, that passion faded.
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.
