Gender Bending Flies: Searching for 'Gay Genes'

Scientists suspect there may be genes that determine sexual orientation in some way. But so far there have only been clues, no definitive answers. Lynette Kalsnes kicks-off the first in a series of five reports exploring genetics.
Who Owns Our DNA?

Lynette Kalsnes reports on a federal case that will have a lot to say about who owns our DNA once we’ve donated it for research.
Genetics Provide Hope for Personalized Medicine

What if your doctor were able to prescribe a treatment tailored just for you? Based on your genetic makeup, you’d have the right drug, no side effects, in the right dosage. Lynette Kalsnes reports on one young man who has joined a study that he hopes will help determine which drugs are best for children with ADHD.
Scientists Explore Ancestry and Disease Connection

Today's report from the DNA Files series on genetics examines why scientists are looking for links between ancestry and disease and how they deal with the haunting legacy of racism in scientific research.
Scientists Look for Link Between Stress and Disease

A lot of us think of our genes as this sort of immutable force. We’re born with our DNA and it doesn’t change. But scientists are more certain than ever that the environment we live in can cause our genes to mutate, or even function differently.
