Wired Science Season 1 Episode 2 Episode 2

Episode 2 of Wired Science season 1 is an exploration of the fascinating world of genetics. Titled "The Secret in Our Genes," the episode delves into the world of DNA and showcases the cutting-edge research being done in the field of genetics.

The episode kicks off with a visit to the Sanger Institute in the UK, where scientists are working to map the human genome. We learn how DNA sequencing works and how this technology is being used to identify the genetic basis for diseases such as cancer and Alzheimer's.

Next, the show explores the world of epigenetics, which is the study of how our environment can affect our genes. We learn about the work being done by researchers at Duke University, who are studying how exposure to certain chemicals can lead to changes in gene expression. We also hear from Dr. Randy Jirtle, who explains how diet and exercise can affect our genes and potentially even prevent cancer.

The episode then switches gears and explores the world of animal genetics. We meet Dr. Susan Alberts, who studies the social behavior of baboons in Africa. She explains how her research has shown that certain genes may play a role in determining social hierarchy within baboon groups.

The show then takes us to a dairy farm in Wisconsin, where we learn about the science of selective breeding. We meet a group of cows that have been selectively bred for high milk production and hear from the farmer about the benefits of using this type of breeding to improve the genetics of his herd.

Finally, the episode wraps up with a discussion of the ethics of genetics research. We hear from Dr. Robert Pollack, who argues that we need to be cautious when using genetic technology, as it could have unintended consequences. We also hear from Dr. Eric Lander, who believes that as long as we approach the technology responsibly, the potential benefits of genetics research are enormous.

Overall, "The Secret in Our Genes" is a fascinating look at the world of genetics and the cutting-edge research being done in this field. With its mix of science and human interest stories, this episode is sure to appeal to anyone with an interest in biology or medicine.
