...went into the lab and said, 'I don't believe these calorie numbers,' " she says. "So we went out and started collecting foods and sampling their contents." (See 10 myths about dieting...
...studied 29 restaurants and 10 frozen-food products, taking care to select foods that dieters would be likely to choose, which meant that they were said to contain 500 calories or fewer and that, in restaurants, they were among the lowest-calorie items on the menus. Back in the lab, Roberts' tests revealed the high-calorie truth, and the numbers were even more troubling than ordinary dieters would appreciate...
...good news: scientists are learning to manipulate epigenetic marks in the lab, which means they are developing drugs that treat illness simply by silencing bad genes and jump-starting good ones. In 2004 the Food and Drug Administration (FDA) approved an epigenetic drug for the first time. Azacitidine is used to treat patients with myelodysplastic syndromes (usually abbreviated, a bit oddly, to MDS), a group of rare and deadly blood malignancies. The drug uses epigenetic marks to dial down genes in blood precursor cells that have become overexpressed. According to Celgene Corp. - the Summit, N.J., company that makes azacitidine - people...
...equipped with only eight genes of its own—hijacks the genetic material of its host cell, infecting and utilizing the human genes to execute the virus’ own operations, according to Stephen J. Elledge, a professor of genetics at Harvard Medical School and head of the lab in which the study took place. With this understanding, Elledge and his team systematically deactivated every gene in the human genome—testing some 20,000 different genes—using new RNA interference technology, hoping to determine the genes in the host cells that the virus relied upon...
...until then, neither Nolan nor officials at the Centers for Disease Control and Prevention (CDC) are ready to ditch the second dose. For one thing, they note, the level of antibodies does not always translate to actual protection against the flu. "Lab studies are a proxy and work well," says Dr. Anthony Fiore, at the CDC's National Center for Infectious Diseases, who wrote an editorial accompanying the study in the Journal of the American Medical Association. "But until you can show that a single dose is as effective as two, it's probably too soon to pull away from...
