Instead of making a 21st-century apology, South Carolina Gov. Mark Sanford decided to take it “old school,” comparing his extramarital affairs to that of King David. Why not just say you find Pinocchio’s story interesting? Or, let’s see—Bill Clinton, Eliot Spitzer, John Edwards, John Ensign would have also worked! That would have been a surprising admission in an age where extramarital affairs no longer seem to grab our attention. Americans act so shocked when they hear about politicians, celebrities, and athletes having affairs, but I have to believe that many women who are married to men with power are aware of affairs, and accept it. Don’t ask, don’t tell; as long as they receive something in exchange from the

Phototropins, blue-light receptors in plants, are light-activated serine/threonine kinases with a flavoprotein LOV domain as their light-sensing module. In addition to the phototropins found in eukaryotes, gene-sequence analysis predicts that LOV domains should be present in prokaryotes,and archaea. Swartz et al. (p. 1090; see the Perspective by Kennis and Crosson) show that a subset of genes in prokaryotes encodes for proteins that function as light-activated LOV-histidine kinases. Light activation of the LOV domain leads to the formation of a flavin-cysteinyl adduct, which is the photoreceptor-signaling state that activates the kinase domain. Lightactivated LOV-histidine kinases were found in two important plant and animal pathogens and in a marine photosynthetic bacterium and indicate that the LOV-histidine kinases are an important family of bacterial photosensory receptors.
