Lecture to explain better test for aerosol releases

Two Lawrence Livermore National Laboratory scientists will discuss how a safe material made with sugar and non-biological DNA can detect and track unhealthy aerosol releases in an April 3 talk at Las Positas College.

During the free event, scientists George Farquar and Elizabeth Wheeler will explain how FDA-approved food additives, combined with a unique DNA bar code, can produce a microparticle simulating airborne aerosols. The technology, the scientists say, could dramatically reduce costs in testing contaminants. The lecture takes place in the college's Multi-Disciplinary Building Lecture Hall, Room 2420, at 6 p.m.

Admission is free, but there is a $2 parking fee. Las Positas College is at 3000 Campus Hill Drive in Livermore.
