Scientists who specialize in nutritional genomics have only begun to decipher the relationship between DNA sequences, diets and ailments like diabetes, heart disease and cancer. Their hope is that someday your own nutritional geneticist will be able to scan your DNA and tell you exactly how to plan your diet given the genes you've been bequeathed...
...Government Accountability Office. Last week the agency reported to the Senate Special Committee on Aging the results of its probe of four Internet-based firms that - for prices ranging from $99 to more than $1,000 - promise personally tailored "nutrigenetic" advice. Customers provide the firms with a DNA sample in the form of a cheek swab and a detailed description of dietary and lifestyle habits. According to the agency, the reports peddled by these firms are in equal parts misleading, vague to the point of uselessness and based on scientifically dubious claims. The GAO sent in profiles for 14 mock...
...dangerous is direct-to-consumer nutrigenetics? It depends. Two of the firms probed by the GAO coupled their reports with a pitch for what they claimed were supplements designed to address the deficiencies in the DNA profiles of their customers. The supplements, one of which would have cost $1,880 a year, were not substantially different from those available for $35 a year at any drug store. It's not just about money, but safety too. As the GAO points out, not all supplements are harmless to all people...
...military celebration last month, Raul, who became a communist as a youth, well before Fidel, insisted that "only the Communist Party" can rule Cuba and "anything else is pure speculation." But at the same time, Raul may carry more perestroika in his political DNA than Fidel does. When the Soviet Union's lavish economic aid to Cuba disappeared in the early 1990s and many Cubans faced possible starvation, Raul convinced a reluctant Fidel to reopen the island's private agricultural markets as an incentive to increase food production. "Beans are more important than rifles," he insisted. Latell agrees...
...patient with diabetes, for instance, is inserted into an unfertilized egg whose nucleus has been removed; then it is prodded into growing in a petri dish for a few days until its stem cells can be harvested. Unlike fertility-clinic embryos, these cells would match the patient's DNA, so the body would be less likely to reject a transplant derived from them. Even more exciting for researchers, however, is that this technique can yield embryos that serve as the perfect disease in a dish, revealing how a disease unfolds from the very first hours...
