Cold-water fish, snow-dwelling bugs and some grasses have evolved natural antifreeze proteins to avoid turning to ice cubes. Peter Davies, a biologist at Queen's University in Ontario, discusses how these antifreeze substances work, and their applications for human problems--like keeping the ice out of ice cream.

In Full Planet, Empty Plates: The New Geopolitics of Food Scarcity, Lester Brown says the world's food supply is tightening, and the reasons are many. People in developing countries are eating more meat, a grain-intensive food; farmers are overpumping, causing water tables to fall; and crop yields have plateaued, despite technological advances.

Secretary of State Hillary Clinton is "looking forward to coming back to work next week," spokeswoman Victoria Nuland says.

Clinton, 65, was discharged from New York Presbyterian Hospital on Wednesday.

Baseball: The San Francisco Giants, in winning the 2012 World Series, participated in 16 playoff games — and they'd have had more, had they not swept Detroit 4-0 in the World Series itself.

Football: The San Francisco 49ers played 16 games in their entire regular season. Three more wins would make them Super Bowl champions.

There were 155,000 jobs added to public and private payrolls in December, the Bureau of Labor Statistics reported Friday morning.

That's right in line with economists' expectations and is another sign of steady, though modest, growth in employment. In November, employers added an estimated 161,000 jobs. The average monthly gain in 2012 was 153,000 jobs, BLS says. That's the same average as in 2011.

Shocking statistics, such as the U.N.'s estimate that more than 60,000 people have died in Syria since anti-regime protests and fighting began in March 2011, tell only part of the story.

STEVE INSKEEP, HOST:

Good morning. I'm Steve Inskeep.

First, people wore suits and ties, dresses or skirts to work. Then came casual Fridays. Then the tech industry destroyed dress codes. Congress is one of the last places people dress up, and we know how that's turned out.

8:35 a.m. ET. And the answer is: 155,000 jobs added to payrolls in December; the jobless rate held at 7.8 percent. (November's rate was revised up to 7.8 percent.)

Our original post:

Here it comes — the always eagerly anticipated news about jobs and the nation's unemployment rate.

There is plenty in the movie Promised Land that will prompt energy industry insiders to roll their eyes. But the overall issues explored in the film, which is being widely released in theaters Friday, are very real.

A process called hydraulic fracturing has led to drilling booms that are transforming rural communities into industrial zones. Hydraulic fracturing, or "fracking," makes it possible to tap into natural gas reservoirs deep underground. But first, gas companies have to convince landowners to allow them to drill.
