Shedding Our DNA Chains The article on epigenetics was thought provoking [Jan. 18]. I had always considered that natural selection was too slow and random a process to allow the animal kingdom to successfully deal with environmental change. I am now filled with hope and trepidation about the effects that future environmental challenges will have on the human race. If physiological conditioning can have a transient effect on our gene activity, then can sociological conditioning also determine the traits of future genetics such as physical appearance, attraction, sexual orientation, academic and sporting prowess? Are changes in epigenetic marks the driving...
...still known primarily as the daughter of Jane Birkin, the gamine English model and actress, and Serge Gainsbourg, France's beloved singer-songwriter. When Serge died in 1991, the nation went into mourning and President François Mitterrand lauded him as "our Baudelaire, our Apollinaire." Carrying such celebrated DNA can be a daunting task. "With acting I never have to reference my father," Gainsbourg says. "With music I want to refer to him, but I want to find my own path, too." (See TIME's fond farewells...

...mind-body medicine for a cancer center that offers seminars on how patients can benefit from this emerging science, I can attest that most have never heard of epigenetics. Yet everything in our environment--the way we think and feel, our exposure to stress--affects the way our DNA is expressed. Once we understand this premise, we can incorporate strategies to effect epigenetic changes--including neurogenesis, the growth of new nerve tissue in the brain...
...chocolate for all tastes. The U.S. Department of Agriculture (USDA) is working with a local research center in San Martin, the Institute for Tropical Crops (ITC), to identify new varieties of cacao beans. The institute is studying 342 specimens collected from 12 watersheds. "We are working on categorizing the DNA of cacao," says ITC director Enrique Arevalo. The work will eventually lead to the creation of a Peru-specific chocolate that could be marketed the way countries sell wine. Hiderico Bocangel, general manager of San Martin's Oro Verde cooperative, says Peru is already creating a niche in the chocolate...
