How a spoonful of sugar helps national security

Submitted By Ted Kaye

Las Positas College announced today that Lawrence Livermore National Laboratory scientists George R. Farquar, Ph.D. and Elizabeth K. Wheeler, Ph.D., will be the speakers at the fourth evening of this yearÕs Annual Science and Engineering Seminar Series at the College on Thursday, April 3. The evening with Drs. Farquar and Wheeler is open to the general public.

This yearÕs series is the fourth joint venture of Las Positas College and Lawrence Livermore Labs to explore the overall issue of ÒTheory to Practice: How Science Gets Done.Ó Drs. Farquar and Wheeler will discuss the topic ÒA Spoonful of Sugar Helps National Security Risk Go Down: DNA Tagged Reagents for Aerosol Experiments.Ó The public is invited to hear these two local scientists discuss how a safe simulant material made with sugar and non-biological DNA can track and quantify indoor and outdoor air transport.

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.

As a community outreach effort, there is no charge for admittance but visitors are reminded that the campus has a $2 parking fee.
