The DNA Files brings compelling stories to public radio, the Web and the community — to illuminate emerging genetic science and its ethical, legal and social implications. SoundVision Productions feedback@dnafiles.org clean http://www.dnafiles.org/podcast/2009-04-06/law-genetics-identity Ethical, Legal &amp; Social Issues Podcast 57:49 SoundVision Productions We've heard a lot about DNA forensics in the news — the process of testing DNA, finding DNA matches, and creating DNA profiles of individuals makes for great headlines. But what exactly is DNA forensics, and how does it work? This episode of The DNA Files was produced in 1998.

Now, genetic researchers are beginning to write their own account of our origins, through the study of DNA. This program, originally produced in 1998, tells us how DNA may have come into existence and how genetic studies have contributed to evolution theories so far. And it explores the controversies raised by genetic research.

The first gene transfer trials were approved in 1989, but the field has yet to live up to its early hope and hype. The basic concept of gene therapy remains seemingly simple: introduce into a target cell a piece of genetic material that will either cure the disease or slow down its progression. Unfortunately, researchers still struggle to safely deliver genes to the right place. Patients' immune systems often see viral vectors as exactly what they are, viruses, and attack accordingly. Furthermore, scientists warn that certain forms of gene therapy may cause patients to develop cancer when the inserted genes disrupt the normal process of healthy cells.

We hear from scientists who were translating research into products and trying to answer the questions that arise about ownership, academic freedom, and public trust in science. Biotechnology is an increasingly global effort, with increasing levels of controversy as well.

In this episode from 1998, learn about the field of behavioral genetics and explore whether you carry some of your fate in your genes.

This program looks at how scientists track these changes, how plants and animals adapt to them or not, and what this means for the health of the planet. From a tiny bog mosquito to the corals of Australia’s Great Barrier Reef, the program discovers how living things are affected by warming trends. Who wins and who loses on a warming planet. clean Wed, 12 Dec 2007 03:00:00 -0500 noah 312 at http://www.dnafiles.org http://www.dnafiles.org/podcast/2007-11-28/rewriting-heredity <!--paging_filter--> Community Ecology &amp; Environment Ethical, Legal &amp; Social Issues Ethics Gene-Environment Interaction Health &amp; Medicine Human Genetic Testing &amp; DNA Analysis Law &amp; Public Policy Podcast Public Response &amp; Participation Research Social Justice Systems Biology 50:52 SoundVision Productions At first, geneticists thought studies of genes and inheritance held the answers to both the cause and treatment of disease. Now, they realize that genes do not act alone and that environment -- from our cells to our neighborhoods -- works in concert with our genetics. Researchers are connecting just how the minute genetic variations among people influence why some are more sensitive to pollution or how the variations in our living conditions can change health on a molecular level.

Humans and chimps share most of their DNA, nearly as much with mice, and a good proportion with non-mammals such as bees and birds. Researchers examine these similarities and differences to learn more about the human race.

Some say manipulating genes in plants and animals is the solution to world hunger; others say it's not safe to eat or grow. The Enviropig, for example, developed by researchers in Guelph, Ontario. The pig is genetically modified to produce less phosphorus, and might one day make pig farming less harmful to the environment. The program also travels to India to explore rice genetically fortified with beta-carotene to ward off diseases that come from Vitamin A deficiency.

And it won't just affect your mind; it'll change your brain -- literally. Researchers today are grappling with the interplay between the inner mind and the outer world and looking at how the brain a person is born with changes in response to the cultural, social, personal, and physical environments the person lives in.
