Guest guest Posted October 16, 2007 Report Share Posted October 16, 2007 tonight, Oct 15, 2008, a TV science show called GHOST IN YOUR GENES http://www.pbs.org/wgbh/nova/genes/ ( " Experts investigate how a mysterioius 'second genome' helps determine our biological fates " ) is on PBS's Nova series, a very well respected science show. it airs tonight in boston and likely other US cities. but to find when it airs in yr community, check out the PBS station schedule in yr area. it will likely air a few times in the next 24 hours. more below.... - rivka _____ Nova Ghost in Your Genes Nova explores new findings that call into question the long-held belief that all inherited traits are passed on by our genes. The fast-growing field of epigenetics investigates hidden influences that could affect not only our health today but that of our descendants far into the future. It now seems that our environment makes small chemical changes to our DNA without affecting the gene's overall makeup. To put it another way, epigenetics adds to our DNA another layer that acts as a control system of " switches. " Experiential factors such as nutrition or stress may trigger these switches and turn genes on or off. These subtle changes can then be " remembered " and passed on from generation to generation, altering inherited traits. This means that the lives of our grandparents - the air they breathed, the food they ate, even the things they saw - could have directly affected us, and what we do may, in turn, affect our grandchildren. Ghost in Your Genes explores this new idea, interviewing scientists in the field and following what could be a paradigm shift in the way in which we think about inheritance and genes.
