Hour Two:
Light and Radio Frequency Pollution / Lefties: The Science of Handedness


Advances in electronic communication may be making life easier on earth, but they're making it harder and harder to get a view of the sky. Astronomers are finding their optical observations blotted out by light spilling out from cities, and their radio observations are filled with the hiss and pop of unwanted radio interference.

We'll talk to two astronomers about the problems that modern culture is bringing to astronomy in both the visible and the radio portions of the electromagnetic spectrum. Plus, information on something that you'll hopefully be able to see - the Perseid Meteor Shower.

Plus ... August 13th is International Lefthanders Day, and Science Friday is celebrating a bit early. We'll be talking to the author of a book about lefthandedness for lefties, and, on a more serious note, to a researcher who believes that he has found a genetic link for handedness.

Dr. Amar Klar, a researcher at the genetics laboratories for the National Cancer Center has found that people who inherit a specific gene, from either parent or both, are born right-handed. People who lack the gene altogether have 50/50 odds of being either right- or left-handed.
