This Week in Science

In Science this week, researchers from Baylor College of Medicine reported on the identification of a complete set of proteins required for mutagenic DNA repair in Escherichia coli, an insight that may lead to new drug targets against pathogens. Using a comprehensive screen, the team identified a network of around 93 genes that function in mutation, many of which operate upstream of activation of stress responses, suggesting that they sense stress.
