What's more, any such effects of nurture (environment) on a species' nature (genes) were not supposed to happen so quickly. Charles Darwin, whose On the Origin of Species celebrated its 150th anniversary in November, taught us that evolutionary changes take place over many generations and through millions of years of natural selection. But Bygren and other scientists have now amassed historical evidence suggesting that powerful environmental conditions (near death from starvation, for instance) can somehow leave an imprint on the genetic material in eggs and sperm. These genetic imprints can short-circuit evolution and pass along new traits...
...staggering. For decades, we have stumbled around massive Darwinian roadblocks. DNA, we thought, was an ironclad code that we and our children and their children had to live by. Now we can imagine a world in which we can tinker with DNA, bend it to our will. It will take geneticists and ethicists many years to work out all the implications, but be assured: the age of epigenetics has arrived...
...Obama's everything now. The fact that he faces a complete mess left by the previous Administration cannot be ignored. It took many years to get us into it. It will take some time to get us out. Corey Seeman Saline, Mich...
...both widespread cultural biases and an indifferent government has been an uphill battle. After nearly a decade of campaigning by activists, with Wong in the forefront, Hong Kong's government in July 2008 put into effect its first anti-racial-discrimination legislation, which in theory allows individual residents to take action against businesses and employers that have discriminated against them because of their skin color. But the law is difficult to enforce and, unlike other ordinances covering gender and disability, exempts many government bodies. A U.N. committee on eliminating racial discrimination, based in Geneva, voiced concerns over...
...carefully read the freelancer contract, the 54-page ethics booklet, and the conflict of interest questionnaire, the specific rule I violated would have been clear," she wrote, adding that editors had never discussed the rules with her. "I should have read them carefully, and I take full responsibility for what was clearly my mistake...
