Genetics roundup: The secrets of DNA, peering into Watson’s genome — and yawning, and more

What secrets lurk in the heart of DNA? – Didn’t the Human Genome Project answer that question? Think again. Last week, scientists involved in a project called Encode reported on a detailed analysis of one percent of the genome, and the findings have undercut a host of conventional wisdom about how genes and DNA work. Most notably, the Encode study suggests that much of the genome — the long stretches of seemingly inactive genetic “letters” surrounding… Continue Reading

Roundup: Genetic links to breast cancer, Avandia under attack, death and the drug official, and more

More genetic links for breast cancer – Whole-genome association studies that tease out links between minute genetic variations and the likelihood of disease are definitely building momentum. Over the last several days, researchers reported six new variations that increase the risk of breast cancer for women who have inherited them. (For background, see this Boston Globe piece or my recent take on the subject.) It’s now conceivable that scientists may soon have an excellent handle on… Continue Reading
