Biology professor Kelly Hughes in his University of Utah lab. He is senior author of a new study showing that salmonella bacteria -- like plague and certain other disease-causing bacteria -- use a molecular ruler or tape measure to determine the length of the bacterial "injectisomes," which are needles these bacteria use to inject infection-promoting proteins into target cells. The study, co-authored by doctoral student Daniel Wee, has potential long-term applications for new antibiotics and targeted anticancer drugs, and for helping people design machines at the nanoscopic or molecular scale.
