...ed from Earth. This mass-extinction event may hold clues to current global carbon cycle changes, according to Jonathan Payne, assistant professor of geological and environmental sciences. Payne, a paleobiologist who joined the Stanford faculty in 2005, studies the Permian-Triassic extinction and the follow...Penn researchers discover how key protein stops inflammation
...boratory Medicine, Carmody and others searched for clues as to how Bcl-3 controls inflammation by examining how Bcl-3-deficient mouse cells respond to infection. Their studies revealed that Bcl-3 interacts with p50, a protein that inhibits gene transcription by binding to DNA. p50 turns off the DNA regio...American Chemical Society's Weekly PressPac -- July 18, 2007
