Science

It's a brand new year for 13.7 (our 4th!), and I'm pleased to kick off our 2013 return to regular posting with some thoughts on the human propensity to say (or think) one thing and do another.

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.

Dealing will climate change will demand our best creative capacities. In the wake of Hurricane Sandy the vulnerabilities of New York City have become all to apparent. Clearly a response is required.

A recent post on Atlantic Cities by Roy Strickland gives a great example of what such creative responses to a changing planet on the local level can look like. As he describes it:

IRA FLATOW, HOST:

And now joining us is Flora Lichtman. Hi, Flora.

FLORA LICHTMAN, BYLINE: Hi, Ira.

FLATOW: Multimedia editor with our Video Pick of the Week, and it's topical, of course.

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.

In 2012 the Higgs boson was spotted at CERN, private company SpaceX began supply flights to the International Space Station, and the world bade farewell to the Galapagos tortoise Lonesome George. A panel of journalists discusses the year's top stories in science.

The comet ISON, discovered by two amateur astronomers last year, will zoom past the Earth next fall. But where did it come from? Astronomer Andrew Fraknoi says a passing star could have flung the comet our way from the Oort Cloud, a distant realm of ice chunks at the outer limits of the solar system.

Whether you're a homeowner who bought an energy-saving refrigerator last year or a company hoping to build a wind farm, the tax package Congress just approved may give you a reason to cheer.

"It's got something in there, a Christmas gift if you will, for almost everyone — American homeowners, workers who commute via transit, and manufacturers of efficient equipment like clothes washers, dryers, refrigerators," says Kateri Callahan, president of the Alliance to Save Energy.
