palegray.net writes "Wired reports on new research into the phenomenon of 'silenced genes', genetic constructs that have no 'partner' in case one goes wrong over the course of your lifetime. Scientists at Duke University have mapped some 200 genes that may 'play a profound role' in the health of the average human. 'Many of the newly found imprinted genes are in regions of chromosomes already linked to the development of obesity, diabetes, cancer and some other major diseases, the researchers reported ... Scientists had thought imprinted genes would account for about 1 percent of the human genome. While scientists must double-check that the newly identified ones are truly silenced, the new map matches that tally.'"
