Talk of the Nation on KCCU-HD2

ARI SHAPIRO, HOST:

This is TALK OF THE NATION. I'm Ari Shapiro in Washington. Neal Conan is away. Well, Congress averted the milk cliff. A five-year farm bill was set to expire, and it could have doubled the price of milk if that had happened. But instead of passing a new five-year plan, Congress extended parts of the old farm bill. That renews subsidies for grain, cotton and soybeans; it cuts budgets for some organic and environmental initiatives.

Scientists have cooled potassium gas to one billionth of a degree below absolute zero. But in the quantum world, that's actually hotter than the Sun. It's hotter, even, than infinity degrees Kelvin. Vladan Vuletić, a quantum physicist at MIT, talks about this 'Bizarro World' temperature.

Catfish eating pigeons, water travelling uphill, a blue whale barrel roll — where can one see such things? The scientific journals! Flora Lichtman and Ira Flatow look back on the year's best moments in science cinema. What was your favorite science video of the year?

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.
