NASA Science Seminar “Arsenic and the Meaning of Life” — Tuesday Dec. 7, 1 – 3 p.m.

Employees and the public are invited to attend a scientific presentation by U.S. Geological Survey research hydrologist Dr. Ronald Oremland about the role of arsenic in microbial life and the microbial ecology of California’s Mono Lake. This NASA science seminar will be held Tuesday, Dec. 7, 1 – 3 p.m., in the Headquarters auditorium.

Oremland is a senior scientist with the USGS Water Resources Division in Menlo Park, Calif., and a principal investigator with NASA’s Exobiology and Evolutionary Biology Program, an element of NASA’s Astrobiology Program. He is a co-author of the paper on arsenic findings published last week in Science Express and announced during the Dec. 2 NASA press conference.
