Novel experiment documents evolution of genome in near-real time
A team led by bioengineering researchers at UC San Diego report in the November issue of Nature Genetics rapid evolutionary changes in a bacterial genome, observed in near-real time over a few days. Scientists have previously published static "snapshots" of the genome sequences of more than 100 bacterial species, from the harmless to those that cause plague, but this new report shows how these ge...Linheng Li Lab documents the development of cancer stem cells
Xi He, M.D., Research Specialist II, and Linheng Li, Ph.D., Associate Investigator, are the first and last authors, respectively, on a new publication that clarifies how normal stem cells become cancer stem cells and how cancer stem cells can cause the formation of tumors. The paper, "PTEN-deficient intestinal stem cells initiate intestinal polyposis" was posted to the Nature Genetics Web...Research Documents Children’s Exposure to Pesticide
Two studies of immigrant farmworker families in North Carolina and Virginia found evidence of pesticide exposure in young children// , and prompted researchers to call for pesticide safety training for workers’ spouses. In the American Journal of Industrial Medicine, researchers from Wake Forest University School of Medicine report that urine samples from 60 children revealed higher le...Valiathan Committee Seeks Documents from AIIMS
