This Week in Science

In Science this week, investigators from Oak Ridge National Laboratory report on the genetic basis for mercury methylation, the process of converting mercury into the neurotoxin methylmercury, by bacteria. The team examined the genomes of two sulfur-reducing bacteria — Desulfovibrio desulfuricans ND132 and Geobacter sulfurreducens PCA — and found that two genes, if deleted alone or together, abolishes the organisms' ability to process mercury.
