Programmed Cell Death Activates Latent Herpesviruses

Researchers have found that apoptosis, a natural process of programmed cell death, can reactivate latent herpesviruses in the dying cell. The results of their research, which could have broad clinical significance since many cancer chemotherapies cause apoptosis, was published ahead of print in ... Read More

Human antibodies that neutralize respiratory droplet transmissible H5N1 influenza viruses

There have been several outbreaks of highly pathogenic H5N1 avian influenza viruses affecting humans over the past decade, the causes of which have been limited to direct human contact with infected birds. Recent publications suggest that a very small number of coding mutations in the viral HA g... Read More

Your Gut Bacteria May Predict Your Obesity Risk

Bacteria in people's digestive systems -- gut germs -- seem to affect whether they become overweight or obese, and new research sheds more light on why that might be.

The findings, from an international team of scientists, also suggest that a diet heavy in fiber could change the makeup of the... Read More

Gut Lecture

Over the many years that I taught microbiology to medical students, perhaps my least favorite lecture was the one on the “normal flora,” what we now call the microbiome. What used to make me grumpy was that I could talk only in vague generalities, rambling about the intestinal flora being an imm... Read More
