Discovery could lead to breakthrough for non-small cell lung cancer (December 3, 2010) -- A professor of biochemistry and molecular biology has discovered a previously unknown mechanism in non-small cell lung cancer cells that contributes to their ability to maintain and grow tumors. ... > full story
The gene-environment enigma (December 3, 2010) -- Personalized medicine centers on being able to predict the risk of disease or response to a drug based on a person's genetic makeup. But a new study suggests that, for most common diseases, genes alone only tell part of the story. Their research shows the environment interacts with DNA in ways that are difficult to predict, even in simple organisms like single-celled yeast. ... > full story
Breast CT imaging system marches forward as pain-free tool to aid mammograms (December 3, 2010) -- While questions persist about the best ways to detect breast cancer early, a CT imaging system first unveiled five years ago is in a better position today to enter the fray -- at least in a supporting role to conventional mammography. ... > full story
