Natural Gut Viruses Join Bacterial “Cousins” in Maintaining Health and Fighting Infections

In a study led by Ken Cadwell, PhD, at NYU Langone Medical Center, microbiologists say they have what may be the first strong evidence that the natural presence of viruses in the gut—or what they call the ‘virome’—plays a health-maintenance and infection-fighting role similar to that of the intestinal bacteria that dwell there and make up the “microbiome.” In their report on their work published in the journal Nature online, the researchers say they also found that MNV bolstered the immune system in fighting off tissue damage.

Calorie-Restricting Diets Slow Aging, Study Finds

The adage 'you are what you eat' has been around for years. Now, important new research provides another reason to be careful with your calories. In a study led by NYULMC neuroscientist, Stephen D. Ginsberg, PhD, and presented at the Society for Neuroscience annual meeting in Washington, D.C., researchers have shown that calorie-reduced diets stop the normal rise and fall in activity levels of close to 900 different genes linked to aging and memory formation in the brain.
