Technique plucks rapidly evolving genes from a pathogen's genome
...er it has been pressured to change or pressured to stay the same. "We're coming out with a similar end result - knowing what kinds of evolutionary pressures are on different genes - but we can do it with just a single genome sequence, instead of lining up genes from different genomes and comparing sequenc...Gene defect linked to premature aging

"In order to grow and stay alive, cells depend on the PASG gene to reduce the activity of other genes, but it's a very complicated process - much like modifying the engine of an F-15 fighter jet while it's flying," says Robert Arceci, M.D., Ph.D., King Fahd Professor and Direc...Hopkins scientists overcome main obstacle to making tons of short, drug-like proteins
