A Warmer Connecticut River and A Look at Autism

The Vermont Yankee Nuclear Power Plant wants to increase the temperature of the water it releases into the Connecticut River. That could make part of the river warmer by one degree. That may not sound like a lot, but some worry that this could hurt local fish populations. We'll talk with a biologist to find out whether one degree should really cause much concern. Shay's guest is Keith Nislow. He's a Research Fisheries Biologist for the federal Forest Service.

Later in the show we look at autism. A group of studies has refuted the suggestion that a childhood vaccine is causing the condition in some children. Researchers and experts in developmental disorders related to the central nervous system are uncertain why there's an increase in the number of autistic diagnoses. We'll talk with geneticist Dr. John Moeschler of Dartmouth Medical School about where the science and study of autism is today.
