No, I'm not talking about the lousy cold you have, or the H1N1 flu (for which I just got a vaccine), or the seasonal flu. I'm talking about how researchers in Japan and at the University of Texas at Arlington have discovered that eight percent of the genetic make-up of humans and other mammals comes from an outside virus and not from our ancestors. After infecting a body, the viral DNA inserts itself into the body's cell nuclei (endogenization), and some of its genetic material is subsequently passed along to the host's offspring. The scientists plan to investigate whether such infections by bornavirus genes are the cause of some human psychological afflictions such as schizophrenia. The research appeared in the science journal Nature.

What makes humans unique? Do we have characteristics that make us different from other animals? PBS will be broadcasting a three-part series on the topic this fall. In advance of the series premiere, the producers want you to tell them why humans are special. You can submit a photo, a video, or text. Some entries will appear on screen, so make a grab for your 15 seconds of fame, and send in your ideas.
