Insulator Helps Silence Genes in Dormant Herpes Virus (5/4/2007)

By adulthood, most people have suffered at least one bout of painful cold sores brought on by the Herpes simplex virus 1, also known as HSV-1. After the initial infection, the virus usually remains in the body, hiding out in nearby nerve cells where the victim's immune defenses cannot reach it, causing no symptoms at all. ...> Full Article

Molecular Marker May Help Identify Pancreatic Cancer And Possibly Predict Survival Time (5/4/2007)

Preliminary research suggests that the expression pattern of microRNA (a short RNA molecule) may be useful in differentiating between chronic pancreatitis and pancreatic cancer and may be able to distinguish long and short term survival time for patients with pancreatic cancer, according to an article in the May 2 issue of JAMA. ...> Full Article

Researchers Discover First Gene That Specifically Links Calorie Restriction To Longevity (5/3/2007)

In studies going back to the 1930's, mice and many other species subsisting on a severely calorie-restricted diet have consistently outlived their well-fed peers by as much as 40 percent. But just how a diet verging on the brink of starvation extends lifespan has remained elusive. ...> Full Article
