How a microbial biorefinery regulates genes

Digesting lignin, a highly stable polymer that accounts for up to a third of biomass, is a limiting step to producing a variety of biofuels. Researchers at Brown have figured out the microscopic chemical switch that allows Streptomyces bacteria to get to work, breaking lignin down into its constituent parts.

A privacy risk in your DNA

Prof. Eran Halperin has found that advances in DNA sequencing carry with them an enormous risk - the theft of personal information from genetics databases poses a serious threat to privacy. He urges that new legislation concerning the maintenance of private and public databases, as well as anti-genetic-discrimination laws, should be drafted.
