Lawrence Livermore National Laboratory scientists George R. Farquar and Elizabeth K. Wheeler will be the keynote speakers at the annual Science and Engineering Seminar Series at Las Positas College at 6 p.m. tonight.
The program is the fourth joint venture of the college and the Livermore Lab to explore the overall issue of "Theory to Practice: How Science Gets Done."
Farquar and Wheeler will discuss the topic "A Spoonful of Sugar Helps National Security Risk Go Down: DNA Tagged Reagents for Aerosol Experiments."
They will explain how FDA-approved food additives combined with a unique DNA bar code can produce a microparticle that simulates the aerosols comprising the air around us. The potential for creating unique bar codes is virtually unlimited, thus allowing for simultaneous and repeated releases, which dramatically reduces the costs associated with conducting source attribution testing for contaminants.
The lecture, which is open to the public free of charge, will start at 6 p.m.in the college's Multi-Disciplinary Building Lecture Hall, Room 2420. Parking on the campus costs $2.
