A Global Scale Scenario for Prebiotic Chemistry: Silica-Based Self-Assembled Mineral Structures and Formamide

A Global Scale Scenario for Prebiotic Chemistry: Silica-Based Self-Assembled Mineral Structures and Formamide

Saladino, R.; Botta, G.; Bizzarri, B. M.; Di Mauro, E.; Garcia Ruiz, J. M., Biochemistry 2016, 55 (19), 2806-2811. Download paper. The pathway from simple abiotically made organic compounds to the molecular bricks of life, as we know it, is unknown. The most efficient geological abiotic route to organic compounds results from the aqueous dissolution of olivine, a reaction known as serpentinization (Sleep, N.H., et al. (2004) Proc. Natl. Acad. Sci. USA 101, 12818–12822). In…

Growth Behavior of Monohydrocalcite (CaCO3·H2O) in Silica-Rich Alkaline Solution

Growth Behavior of Monohydrocalcite (CaCO3·H2O) in Silica-Rich Alkaline Solution

Zhang, G.; Delgado-López, J. M.; Choquesillo-Lazarte, D.; García-Ruiz, J. M., Crystal Growth & Design 2015, 15 (2), 564-572. Download paper. Monohydrocalcite (CaCO3·H2O) has been crystallized in silica-rich alkaline water solution. The crystallization proceeds by a counterdiffusion method without the presence of any other additive except dissolved silica. The crystallization has been followed in situ by optical microscopy and Raman microspectroscopy, while the time evolution of the pH and the concentration of calcium and silica species…

Sobre los Experimentos de Creación de Vida de Andrew Crosse

Garcia-Ruiz, J. M., Macla 2015, 20, 61-62. Uno de los personajes más exitosos y conocidos de la historia de la literatura y el cine de ficción es el creado por la escritora Mary Shelley en 1817 en su libro “Frankenstein o el moderno Prometeo”. Paradójicamente, uno de los científicos menos conocidos y más misteriosos de la historia de la ciencia británica es Andrew Crosse, el individuo real en el que, según se suele afirmar, Mary…

Teaching High School students at Limuru

Teaching High School students at Limuru

During the first trip to the Rift Valley of the Prometheus Project, I asked my Kenyan contact Patricia Gitari to seek for the possibility to organize an event to transfer high school teachers in Kenya my experience in popularization and teaching of crystallography. She did a great work, and she organized in Limuru, a town near Nairobi, an exceptional event. She was able to attract more than 150 students and teachers from different schools of…

Electra Kotopoulou

University of Granada, started 2015 Hi! I am a Greek PhD student at CSIC-UGR and I joined J.M. García-Ruiz group and Prometheus team in October of 2015. I hold a BSc in Geology and a MSc focused in Geochemistry-Mineralogy, from the University of Athens. During my Master thesis I studied S-Fe-As mineralogy, speciation and geochemistry in marine sediment cores from the shallow-sea hydrothermal vents of Milos volcanic island (HVA, Greece) with the use of various…

Field trip to Dallol

Field trip to Dallol

The field trips to Dallol have been successfully performed in January 2016 and January 2017. We have collected samples of liquid, gases, air and air particles, etc… and make numerous in-situ measurements of physical and chemical variables such as pH, temperature, pressure, salinity, conductivity, oxygen, redox, visible spectra, etc… The aim of this project is to perform: A rigorous study of the hydrochemistry of the brines including the analysis of the organic compounds and gases. …

Prometheus at the Science Week

Prometheus at the Science Week

Science is essential for the evolution of the humanity. This is the reason why science community should encourage kids, teenagers and adults to explore the magic world of science. The Week of Science (November 7-12, 2016) is an event that offers the opportunity to get a closer look at the work that scientists do. We invited the students of several schools of Granada to join our journeys inside giant crystal caves in Mexico, camp in…
