The genomes of most higher organisms contain sequences from retroviral genomes called endogenous retroviruses (ERVs). These are DNA copies of retroviral RNAs that are integrated into the germ line DNA of the host, and passed from parent to offspring. In most species the infections that lead to g... Read More
The Koala retrovirus (KoRV) continues to spread within Australia, according to results of a new analysis of a larger sample size from a wider geographical range than was previously studied. Read More

One of the basic requirements of evolution is variation in a population upon which selection can act. One of the sources of variation is mutation in DNA. These changes may or may not be reflected in the ensuing amino acid sequence of a protein. This exercise explores the additive effects of m... Read More

As my Fall semester approaches, I am reflecting on last Fall. I taught a freshman seminar course revolving around symbioses and parasitism, and was fortunate to have many well known scientists be willing to "virtually visit" my class! Here is my report from last year on the great Jack Gilbert.... Read More

Influenza A viruses typically cause severe respiratory disease mainly in the very young or the elderly. The 2009 swine-origin H1N1 virus is unusual because it preferentially infects individuals under 35 years of age. We’ve previously noted that being older is a good defense against 2009 H1N1 inf...
