...Certainly, defining what we mean when we say life has become a moving target over the years. Are we alive? Yes. Is a virus alive? Maybe. Still, a half-century after the discovery of the double helix, nobody doubts that it is our DNA that determines what we are - in the same way that lines of code determine software or the digital etchings on a CD determine the music you hear. Etch new signals, and you write a new song. That, in genetic terms, is what Venter has done. Working with only the four basic nucleotides that make...
...shingles vaccine has been available since 2006, but to date, only 2% of Americans 60 and over have been vaccinated against the disease, an extremely painful condition caused by the chickenpox virus that hits 1 million new patients a year - almost half of all unvaccinated adults who live to 85.

But that ended abruptly on Sept. 11, 2001, when Karen Hughes changed pronouns at a White House press conference: "Your Federal Government continues to function effectively...
...Prior to the study, researchers had identified only a few dozen molecules needed by the virus to infect human cells. Because AIDS progression hinges on their presence, targeting them could slow infection...
