11:59:60 — Look For An Extra Tick Of The Clock Tonight
If you're worried about finishing everything on your to-do list, you'll get an extra second today to cram it all in. The extra second is called a "leap second." At the very end of the day, the clock will read 11:59:60 Universal Time (the official time ...

The Test That Can Look Into A Child's (Reading) Future
If this isn't an honest-to-goodness crystal ball, it's close. Neurobiologist Nina Kraus believes she and her team at Northwestern University have found a way — a half-hour test — to predict kids' literacy skill long before they're old enough to begin ...

To Keep Up With Earth's Rotation, Clocks Will Tick An Extra Second Tonight
There is an extra "leap" second in Tuesday's clock. The second is designed to keep the clocks in synch with earth's rotation, but some people would like to take it away. ROBERT SIEGEL, HOST: Today saw important deadlines for the Greek debt crisis and a ...

How Finns Make Sports Part Of Everyday Life
In Helsinki, sports facilities pop up all over the place, sometimes in some pretty odd nooks and crannies. One bomb shelter hosts an archery club, another an underground swimming pool and an ice hockey rink. Though they hardly need it, there's a ...

Screaming For Science: The Secrets Of Crying Babies And Car Alarms
"That's why you want to throw your alarm clock on the floor," Poeppel says. The researchers in Poeppel's lab decided to study screams in part because they are a primal form of communication found in every culture. And there was another reason. "Many of ...

If you're worried about finishing everything on your to-do list, you'll get an extra second today to cram it all in. The extra second is called a "leap second. " At the very end of the day, the clock will read 11:59:60 Universal Time (the official time that international timekeepers use) or 7:59:60 p. m. ET. Astronomers at the International Earth Rotation and Reference Systems Service in Paris decided... Leap seconds are added to keep those atomic clocks in sync with a time standard tied to the rotation of the Earth. "Atomic time, on the other hand, defines a second as exactly 9,192,631,770 oscillations of a cesium-133 atom. The Times says that large weather systems, volcanoes and earthquakes can have enough force to change the speed of Earth's rotation. So, while the atomic clock ticks consistently, Earth's rotation changes. NPR's Geoff Brumfiel says that because the changes in Earth's rotation are unpredictable, the addition of leap seconds is also sporadic.
As NPR's Geoff Brumfiel reports, today contains an extra second. GEOFF BRUMFIEL, BYLINE: To understand this thing called a leap second, here's an astronomy lesson. TOM O'BRIAN: The biggest reason is that the moon - the moon's gravity slows the earth's rotation down. BRUMFIEL: Things like major earthquakes and melting glaciers can also change the length of the day. Humans didn't notice until we developed super-accurate atomic clocks and computers. Since the 1970s, we've had to add leap seconds to keep our timepieces in sync with our wobbly planet. And so at 7:59 p. m. Eastern Time tonight, anyone who was watching the official U. S. time saw something weird. O'BRIAN: Fifty-eight seconds, 59 seconds, and then - one time only - 60 seconds. BRUMFIEL: In other words, this particular minute had an extra second in it. Now, leap seconds can cause trouble. Markus Kuhn is a computer scientist at Cambridge University in the U. K. MARKUS KUHN: There is no standardized way of how computers in particular handle it. BRUMFIEL: A previous leap second caused some computers to freeze. KUHN: And a number of bigger computing centers had to shut down and had to reboot all their computers. BRUMFIEL: Leap seconds have crashed airline reservation systems.
In Helsinki, sports facilities pop up all over the place, sometimes in some pretty odd nooks and crannies. One bomb shelter hosts an archery club, another an underground swimming pool and an ice hockey rink. "It's been kind of a social right to provide citizens with sporting possibilities," says Hanna Vehmas , a sports scientist at the University of Jyväskylä. She says it's a Nordic thing to consider sports a social right. That thinking started in the 1970s, when governments started subsidizing sports gyms in even the smallest towns. Now, she says, "there's an estimate of some close to 30,000 sports facilities in this country, which is said to be more per capita than in any other country in the world. Those facilities are one reason why Finland and its Nordic neighbors always make the top-five list of most physically active European countries, according to surveys by the European Commission. These days, municipalities spend about $700 million a year subsidizing sports facilities and clubs. A portion of lottery funds also goes toward funding sports facilities and research. About a fifth of the country belongs to sports clubs or federations. Some people even play sports at work.
