The Calm Before The Storm: An Interview With Dr. Gilbert Levin: "One of the Principal Investigators for the NASA Viking biology team was Dr. Gilbert V. Levin who invented and built the Viking Labeled Release Experiment. His experiment tested the soil of Mars nine times at two different landing sites under different temperature regimes and environmental conditions. All his data point to microbes metabolizing a nutrient solution and giving off an indicative radioactive CO2 gas. In 1997, Levin simultaneously reported in my book MARS: THE LIVING PLANET and in an Astrobiology Proceedings paper for the SPIE, that his experiment definitely detected living organisms on the surface of Mars. He has been highly criticized by many of his peers, but certainly not all. With the recent smoking gun evidence of meandering river channels on Mars formed by liquid water, the odds that Mars once had life and still has life today have gone up significantly.

In the following conversation I talk with Dr. Levin about his early work as a Sanitary Engineer and how it got him involved with NASA and the search for life on Mar"

'If these numbers are accurate, they show that the systems we put in place four months ago to develop a police force based on the principles of a free and democratic society are starting to ...

Forum: The fish that threatened national security : "At La Guardia we proceeded to security and the X-ray inspection point run by the Transportation Security Administration. I have learned by now that, post-9/11, a traveler is better off safe than sorry when proceeding through security. I wasn't prepared, however, for the TSA to stop me right at the entrance, proclaiming that no small pets, including fish, were permitted through security. I had, however, just received the blessing of the ticket agents at US Airways and pre-assured MJ's travels with Pittsburgh International Airport security weeks before our travel date. I tried to explain this to the screener who stood between me and the gates, but she would have none of it. I was led back to the US Airways ticket counter, stocking-footed and alone, where the agents reasserted that they did not see a problem for me to have a fish on board, properly packaged in plastic fish bag and secured with a rubber band as MJ was....
