    Simulating The Red Planet, On The Pale Blue Dot

    What's it like to live--and cook--on Mars? To find out, researchers are simulating Mars missions in Russia, and on the slopes of a Hawaiian volcano. Kim Binsted talks about her study to whip up tastier space food. Porcini mushroom risotto, anyone? And sleep expert Charles Czeisler talks about how humans adapt to the 24.65-hour Martian day.

    Elite Colleges Struggle To Recruit Smart, Low-Income Kids

    Top schools often offer scholarships that not only include free tuition, but also free room and board for top students from poor families. Each year, however, colleges are confronted with a paradox: No matter how many incentives they provide, enrollment of highly talented, low-income student barely seems to budge.

    Deep In Canadian Lakes, Signs Of Tar Sands Pollution

    The contaminants researchers found at the bottom of Alberta lakes are from air pollutants coming from tar sands oil production and processing facilities. The pollution wasn't picked up by the industry-funded monitoring program that was supposed to track environmental risks from tar sands over recent decades.

    Negative Temperatures That Are Hotter Than The Sun

    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.

    Cold-Water Fish Break The Ice With Antifreeze

    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.

    'Full Planet, Empty Plates'

    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.

    From Canada To Latin America, The Christmas Bird Count Is On

    Since 1900, citizen scientists across the Americas have braved bad weather and lack of sleep to participate in the yearly count — essentially, a bird-watching marathon. In the process, these birds have created the world's longest-running database in ornithology and given scientists a great tool for assessing the health of bird populations.
