Innovation Hub of 10/27/2012: Politics and Genes. Science of Food.

Here's the lineup for this week.

Politics and Genes

We all know that our surroundings can influence our political leanings, but could our DNA also affect the way we vote? Our guest today discusses that possibility.

Guest:

• Rose McDermott, political science professor at Brown University, co-editor of Man Is by Nature a Political Animal

Science of Food

Why do we cook? No other animals do. But we're meticulous about it -- roasting, fileting, whisking. What does science tell us about why we're like this, why we care, and how food sets humans apart as a species?

Guest:

• David Pogue, technology columnist for the New York Times, host of NOVA ScienceNow and its upcoming episode: Can I Eat That?
