Compounds In Cranberries May Be Antibacterial Agents (11/19/2007)

Cranberry sauce is not the star of the traditional Thanksgiving Day meal, but when it comes to health benefits, the lowly condiment takes center stage. In fact, researchers at Worcester Polytechnic Institute (WPI) have found that compounds in cranberries are able to alter E. coli bacteria, which are responsible for a host of human illnesses (from kidney infections to gastroenteritis to tooth decay), in ways that render them unable to initiate an infection. ...> Full Article

Virus Used to Create Experimental HIV Vaccines Directly Impairs the Immune Response (11/19/2007)

Leading efforts to create an HIV vaccine have hinged on the use of viruses as carriers for selected elements of the HIV virus. Recently, however, evidence has emerged that some of these so-called viral vector systems may undermine the immune system and should not be used for vaccine development. Now, a new study from scientists at The Wistar Institute provides strong support for the idea that some viral-vector vaccines may cause more harm than good. ...> Full Article

Researchers Identify Tumor-Suppressor Gene for Lung Cancer (11/18/2007)

Smac-ing Lung Cancer to Death (11/17/2007)

Researchers have developed a small molecule that can turn the survival signal for a variety of cancer cells into a death signal. The molecule mimics the activity of Smac, a protein that triggers the suicide of some types of cancer cells. ...> Full Article

Scorpion Toxin Makes Fungus Deadly to Insect Pests (11/17/2007)

Professor has discovered how to use scorpion genes to create a hypervirulent fungus that can kill specific insect pests, including mosquitoes that carry malaria and a beetle that destroys coffee crops, but does not contaminate the environment as chemical pesticides do. ...> Full Article

Study Finds That Sitting May Increase Risk of Disease (11/16/2007)

Most people spend most of their day sitting with relatively idle muscles. Health professionals advise that at least 30 minutes of activity at least 5 days a week will counteract health concerns, such as cardiovascular disease, diabetes and obesity that may result from inactivity. Now, researchers at the University of Missouri-Columbia say a new model regarding physical activity recommendations is emerging. New research shows that what people do in the other 15 and a half hours of their waking day is just as important, or more so, than the time they spend actively exercising. ...> Full Article
