It wasn't long ago that Minnesota Congresswoman Michele Bachmann's rise to the top of the Republican field of presidential candidates was called "meteoric." In August, she won the Iowa straw poll. Now, she's polling in the single digits.
But Bachmann is plowing ahead with her campaign and this week she came out with a memoir, Core of Conviction. In it, she writes about her 28 children — five biological and 23 foster kids. She spent much of the 1990s as a stay-at-home mom.
At NPR, we know a thing or two about promotional merchandise. After all, we invented the Nina Totin' Bag and the Carl Kasell Autograph Pillow. So, on this Black Friday, White House correspondent Scott Horsley presents the NPR guide to campaign swag.
Flies are attracted to glycerol, a chemical in beer produced during fermentation. Understanding more about the genes responsible for taste and smell in flies could help make powerful insect repellents.
Scientists in California think they've figure out why flies like beer. That may sound a bit trivial, but in fact it could lead to new ways of combating plant and animal pests.
That flies like beer is well known. "The attraction of flies to beer was first reported in the early 1920s," says Anupama Dahanukar. She's part of an inter-disciplinary program involving neuroscience and entomology at the University of California, Riverside. She's been studying how flies recognize chemicals, so answering the question of why flies like beer is actually quite relevant to her research.
