NIH Scientists Find That Chromosomal Abnormalities Are Associated With Aging And Cancer
nih.gov 3 weeks, 1 day agoTwo new studies have found that large structural abnormalities in chromosomes, some of which have been associated with increased risk of cancer, can be detected in a small fraction of people without a prior history of cancer. The studies found that these alterations in chromosomes appear to increase with age, particularly after the age of 50, and may be associated with an increased risk for cancer. These studies were conducted by two consortia, one led by scientists at the National Cancer Institute (NCI), a

Turning DNA Into A Hard Drive
latimes.com 3 days, 16 hours agoStanford's Drew Endy and his lab figured out a way to turn DNA into a rewriteable data storage device that can operate within a cell.Silicon-based computers are fine for typing term papers and surfing the Web, but scientists want to make devices that can work on a far smaller scale, recording data within individual cells. One way to do that is to create a microscopic hard drive out of DNA, the molecule that already stores the genetic blueprints of all living things.
