Kiva.org

I know this is off-topic, but I recently discovered this organization: www.kiva.org. It is an organization which allows you to extent credit via micro loans ($25 or greater) to individuals. It is not a charitable contribution, but rather a zero-interest loan to help people start or expand businesses. It is amazing to see how a little bit of money can go so far. I am not affiliated or paid by Kiva in anyway. I simply think it is a wonderful idea that appears to be implemented in a well-organized manner. Cheers, Stefan

New Position

My friend Dave chided me for not updating my blog frequently enough. I must admit it is true. It is hard to believe that it has already been over 3 months since I last updated it. Anyway, I now have a new position as a research scientist at the SETI Institute. I am still working at the NASA-Ames Research Center, however. I am currently working on a few different projects, including hypersaline microbial mats from Guerrero Negro, Baja, Mexico. The Exobiology Department at NASA-ARC is planning another trip to the salt production facility - Exportadora de Sal S.A. de C.V. - located in Guerrero Negro, Baja, California Sur, Mexico. This trip we're planning to study some of the higher salinity ponds (on the order of 150 ppt salinity) as opposed to the lower, but still hypersaline ponds of about 85 ppt.

I also have an ongoing project with Dr. Jen Blank of the SETI Institute to study the geology, chemistry and biology of ophiolite rocks found in certain locations in Northern California. Ophiolites are pieces of ocean crust that have been lifted up to the surface and exposed. When these rocks undergo weathering, a number of interesting abiotic chemical reactions can occur, and the water chemistry is highly modified. For example, in the system we are studying (see below), the pH of the water in local streams is roughly 9.0, and the water has high levels of carbonate and magnesium. In addition, we are finding unique microbial communities associated with these waters. More on this as the work progresses.
Cheers,
Stefan
