Next 'Science on Saturday' lecture: The 'bio' in biofuels

"The 'Bio' in Biofuels: New Energy from Ancient Life," by Lab scientists Michael Thelen and Rhona Stuart, and Tracy High School teacher Ken Wedel, is the fourth and final lecture in the Science on Saturday series to be held Feb. 23 at the Bankhead Theater, 2400 First St., Livermore. Two presentations will be offered -- 9:30 and 11:15 a.m.

The most ancient forms of life, bacteria, are exceptionally tiny organisms, yet they have contributed in big ways to the planet. Although long recognized for causing disease, microbes have had a tremendous impact on human survival, and now can help solve some of the urgent energy problems. The presenters will discuss how the microbial production of biofuels represents a new source of energy that can be constantly renewed.

Seating is on a first-come, first-served basis; there is no pre-registration. Directions and maps are available on the Science on Saturday Website. Science on Saturday is presented by LLNL's Science Education Program.
