This Week in Science

Researchers in Seoul this week show that "the pyrroloquinoline quinine-dependent alcohol dehydrogenase activity of a commensal bacterium Acetobacter pomorum modulates insulin/insulin-like growth factor signaling in Drosophila to regulate host homeostatic programs controlling developmental rate, body size, energy metabolism, and intestinal stem cell activity." The team shows that germ-free flies that are monoassociated with pyrroloquinoline quinine-dependent, alcohol dehydrogenase-mutant bact
