Almost 150 years ago, English scientist Francis Galton coined the phrase "nature versus nurture" — and proposed that research on twins could resolve the debate.
Genetics have long seemed to weigh heavily in favor of the role of nature in shaping the people we become. But even identical twins are different to varying degrees, and some researchers believe those differences suggest a third influence at work, called epigenetics.
Last Wednesday, Ann Selzer could not be cajoled into even a hint of the final Iowa poll as she joined the Political Junkie. Selzer and the company - and her company polls for the Des Moines Register and for Bloomberg. It's considered the gold standard in Iowa. And the Register published the results on Saturday night. It showed Mitt Romney in front, followed closely by Ron Paul and Rick Santorum surging into third. Ann Selzer joins us again from Iowa Public Radio. Nice to have you back on the program.
This is TALK OF THE NATION. I'm Neal Conan, in Washington. In Iowa, all the GOP presidential candidates continue to profess their faith in speeches and in broadcast ads, perhaps none more than Texas Governor Rick Perry.
This is SCIENCE FRIDAY. I'm Ira Flatow. When you look back on 2011, what will you remember, the Fukushima nuclear disaster following the tsunami? What about the death of Steve Jobs, founder of Apple and the pioneer of personal computing? How about the world's population reaching seven billion?
This is SCIENCE FRIDAY. I'm Ira Flatow. The New Year's countdown has begun, not at the clock in Times Square but this one for two NASA probes set to orbit the moon this weekend. The twin spacecraft, GRAIL-A and GRAIL-B are expected to enter lunar orbit 24 hours apart, one on New Year's Eve, the other on New Year's Day.

Every year thousands of scientists visit Antarctica. Some study the gas plume from the active volcano, Mount Erebus. Others map the ever-changing ice caves. But they all face the same challenges of working on extreme terrain. Two researchers and a photojournalist discuss how research is done on the frozen continent.
A child of Sri Lankan immigrants, music journalist S.H. "Skiz" Fernando, Jr. grew up eating Sri Lankan food regularly. But he didn't master the art of the cuisine until he moved to his family's homeland and enlisted the expertise of his four aunts.
For one year, Fernando spent his mornings scouring local markets for the best spices and ingredients. He then cooked for hours, using old cookbooks and family recipes. His aunts critiqued the dishes until Fernando perfected them — meaning Fernando ended up making each recipe at least 20 times.
When University of Chicago professor William Dodd assumed the post of U.S. ambassador to Germany in 1933, he hoped for an undemanding position that would allow him spare time to write a book.
At the time, few in the United States or Europe considered then-Chancellor Adolf Hitler a serious threat, and few expected him to remain in power long. Dodd was no exception, says Erik Larson, author of In the Garden of Beasts: Love, Terror, and an American Family in Hitler's Berlin.
