Genetic variation in human gut viruses could be raw material for inner evolution

A growing body of evidence underscores the importance of human gut bacteria in modulating human health, metabolism, and disease. Yet bacteria are only part of the story. Viruses that infect those bacteria also shape who we are. Frederic D. Bushman, PhD, professor of Microbiology at the Perelman ... Read More

RNA virus packaging specificity explained?

In 1969 David Baltimore proposed that poliovirus RNA replication is coupled with packaging, in that only those genomes actively replicating will be selectively encapsidated. From an evolutionary standpoint, it is an ingenious requirement to ensure that only virus genomes capable of replication ... Read More

Modeling social networks

What looks like a Native American dream catcher is really a network of social interactions within a community.

According to the university, the scientist... Read More

Synthetic Stool a Prospective Treatment for C. Difficile

A synthetic mixture of intestinal bacteria could one day replace stool transplants as a treatment for Clostridium difficile (C. difficile). C . difficile is a toxin-producing bacteria that can overpopulate the colon when antibiotics eradicate other, naturally protective bacteria living there.

New study maps hotspots of human-animal infectious diseases and emerging disease outbreaks

A new global study mapping human-animal diseases like tuberculosis (TB) and Rift Valley fever finds that an "unlucky" 13 zoonoses are responsible for 2.4 billion cases of human illness and 2.2 million deaths per year. The vast majority occur in low- and middle-income countries.

The report, wh... Read More

Finding One Bug

A new, nanometer-sized biosensor can detect a single deadly bacterium in tainted ground beef. How? Researchers attached nanoparticles, each packed with thousands of dye molecules, to an antibody that recognizes the microbe E. coli O157:H7.
