Field trip to Aqua de Ney

Field trip to Aqua de Ney

From 8th-14th August we carried out a field trip to Aqua de Ney Spring , an unusual spring in northern California. Aqua de Ney has the highest reported silica concentration (>4000 pm) and pH value (~11.9) in a natural spring. We collected water from these springs, measured in situ the pH and ex-situ silica concentration. Then, we performed experiments with these waters finding that they react with metals to form silica biomorphs and silica gardens (metal…

Summary of main achievements (August 2014-January 2017)

Our project is based on the interaction of two main research lines: 1) The fundamental understanding of the phenomenon of mineral self-assembly and, 2) Its relevance to reveal the transition from non-life to life during the Early Earth. We have made the following progress in both fields: Successful field trips to Aqua de Ney alkaline waters (California), Oman ophiolites and their alkaline springs, Dallol hydrothermal system in Ethiopia, and alkaline lakes in the Southern Rift…

New paper on mineral self-organization, life detection and origin of life

New paper on mineral self-organization, life detection and origin of life

Our last paper on mineral self-organization, life detection and origin of life has just been published in Science Advances: http://advances.sciencemag.org/content/3/3/e1602285.full. This work is one of the dreams of my life as a scientist. For at least 20 years, I have identified the rare and remote places on the planet where there are silica-rich alkaline waters with which I could do the experiments to produce biomorphs. Thus far, without the help of Prometheus, I had not…
