That targeted recruitment strategy is important, because the Census aims to put enumerators to work in the communities where they live. Part of the rationale is saving on transportation costs, but the bigger reason is to increase the chances that people will be willingly counted. "If people recognize you, they're more apt to open up and deal with you than if you're someone from the outside," says Maxwell Biggs, who manages Census recruiting in Florence, S.C. One of Biggs' challenges: hiring enumerators for two of the state's Native American tribes...
...findings are the result of work conducted by Susan Roberts, professor of nutrition at Tufts University, and Jean Mayer, of Tufts' USDA Human Nutrition Research Center on Aging. It was Roberts who initiated the study, and it was her own struggles with weight that got her started. Author of the book The Instant Diet, she was working on new recipes for the paperback version (retitled The "i" Diet) and, as was her practice, used herself as a guinea pig. As a rule, she lost weight on the menu plans she recommended to readers, but when she redeveloped some...
...Sweden are an unlikely place to begin a story about cutting-edge genetic science. The kingdom's northernmost county, Norrbotten, is nearly free of human life; an average of just six people live in each square mile. And yet this tiny population can reveal a lot about how genes work in our everyday lives...
Since 2004, the FDA has approved three other epigenetic drugs that are thought to work at least in part by stimulating tumor-suppressor genes that disease has silenced. The great hope for ongoing epigenetic research is that with the flick of a biochemical switch, we could tell genes that play a role in many diseases - including cancer, schizophrenia, autism, Alzheimer's, diabetes and many others - to lie dormant. We could, at long last, have a trump card to play against Darwin...
...fact, the scientists had mapped only a certain portion of the epigenomes of two cell types (an embryonic stem cell and another basic cell called a fibroblast). There are at least 210 cell types in the human body - and possibly far more, according to Ecker, the Salk biologist, who worked on the epigenome maps. Each of the 210 cell types is likely to have a different epigenome. That's why Ecker calls the $190 million grant from NIH "peanuts" compared with the probable end cost of figuring out what all the epigenetic marks are and how they work in concert...
