Lew receives competitive MURI Award

Matthew Lew, at the McKelvey School of Engineering, is part of a team that received a $7.5 million five-year award under the U.S. Department of Defense’s highly competitive Multidisciplinary University Research Initiative Program (MURI). The team’s research is aimed at developing a new class of functional living electronics based on living materials such as proteins and bacteria.

Research casts doubt on voice-stress lie detection technology

Now, however, it is being touted as a powerful and effective tool for an array of new applications — everything from screening potential terrorists in the nation’s airports to catching wayward spouses in messy marital disputes. Despite its booming popularity, recent federally sponsored studies have found little evidence that existing voice-stress technologies are capable of consistently detecting lies and deceptions. “You could have gotten better results by flipping a coin,” says Washington University in St. Louis psychologist Mitchell S. Sommers, lead investigator on a recent voice-stress study.
