Features Of Replication Suggest Viruses Have Common Themes, Vulnerabilities (8/17/2007)

A study of the reproductive apparatus of a model virus is bolstering the idea that broad classes of viruses - including those that cause important human diseases such as AIDS, SARS and hepatitis C - have features in common that could eventually make them vulnerable to broad-spectrum antiviral agents. ...> Full Article

Researchers Discover New Mechanism for Viral Replication (8/17/2007)

Researchers at the University of Pennsylvania School of Medicine have identified a new strategy that Kaposi's Sarcoma Associated Herpesvirus (KSHV) uses to dupe infected cells into replicating its viral genome.
