Thoughts in Geobiology
Journal of Geology and Mining Research Vol. 1(8), October, 2009 Available online http://www.academicjournals.org/jgmr ISSN 2006 – 9766 © 2009 Academic Journals Editorial Thoughts in Geobiology One of the possible ways to make connection between geologists and biologists is through studying subjects related to the newly established trend “Geobiology”. In the year 1972, Sylvester-Bradley stated that the Earth sciences include not only geology, but the hybrid-sciences geophysics, geochemistry and geobiology, of which the most complex and least rigorous is geobiology. Kump (2008) simply defined geobiology as the field that has recently energized the life and Earth sciences as geologists and biologists bring new tools to collaborations addressing fundamental problems that transcend the disciplines. The book edited by Xiao and Kaufman (2007) includes a set of multidisciplinary reviews on the Neoproterozoic fossil record (animals, algae, acritarchs, protists, and trace fossils), evolutionary developmental biology of animals, molecular clock estimates of phylogenetic divergences, and Neoproterozoic chemostratigraphy and sedimentary geology. The editors of this book believe that these topics are of continuing interest to geoscientists and bioscientists who are intrigued by the deep history of the Earth and its inhabitants. Yildirim et al. (2008) believe that microbial systems in extreme environments and in the deep biosphere may be analogous to potential life on other planetary bodies and hence may be used to investigate the possibilities of extraterrestrial life. I would add that astrobiologists are working on this point through studying materials from Mars. Through geobiology we search for origins and evolution of life, atmosphere, hydrosphere, lithosphere and biosphere, reasons of mass extinctions, interactions between microbes and minerals, global changes, and other subjects of interest. -

51. Astrobiology: the Final Frontier of Science Education
www.astrosociety.org/uitc No. 51 - Summer 2000 © 2000, Astronomical Society of the Pacific, 390 Ashton Avenue, San Francisco, CA 94112. Astrobiology: The Final Frontier of Science Education by Jodi Asbell-Clarke and Jeff Lockwood What (or Whom) Are We Looking For? Where Do We Look? Lessons from Our Past The Search Is On What Does the Public Have to Learn from All This? A High School Curriculum in Astrobiology Astrobiology seems to be all the buzz these days. It was the focus of the ASP science symposium this summer; the University of Washington is offering it as a new Ph.D. program, and TERC (Technical Education Research Center) is developing a high school integrated science course based on it. So what is astrobiology? The NASA Astrobiology Institute defines this new discipline as the study of the origin, evolution, distribution, and destiny of life in the Universe. What this means for scientists is finding the means to blend research fields such as microbiology, geoscience, and astrophysics to collectively answer the largest looming questions of humankind. What it means for educators is an engaging and exciting discipline that is ripe for an integrated approach to science education. Virtually every topic that one deals with in high school science is embedded in astrobiology. What (or Whom) Are We Looking For? Movies and television shows such as Contact and Star Trek have teased viewers with the idea of life on other planets and even in other galaxies.

Is It the First Use of the Word Astrobiology ? Author
Title : Is it the first use of the word Astrobiology ? Author : Danielle Briot Adress : Observatoire de Paris 61 avenue de l’Observatoire 75014 Paris France tel : 33(0)1 40 51 22 39 and 33(0)1 45 07 78 57 [email protected] running title : First use of the word Astrobiology ? 1 Abstract The research of life in Universe is a ancient quest that has taken different forms over the centuries. It has given rise to a new science, which is normally referred as Astrobiology. It is interesting to research when this word was used for the first time and when this science developed to represent the search for life in Universe as is done today. There are records of the usage of the word "Astrobiology" as early as 1935, in an article published in a French popular science magazine. Moreover this article is quite remarkable because its portrayal of the concept of the subject is very similar to that considered today. The author of this paper was Ary J. Sternfeld (1905 - 1980), who was ortherwise known as a poorly respected great pioneer of astronautics. We provide a brief description of his life, which was heavily influenced by the tragic events of the 20th century history, from Poland and France to Russia. He was a prolific scientific writer who wrote a number of very successful scientific books and papers. Keywords : History – Pioneers 2 1. Introduction The question of the life in the Universe, in relation with the question of the multiplicity of worlds, is very ancient and probably dates back to Greek philosophers. -

HAL archives-ouvertes.fr | CCSD, April 2020. Evolutionary processes transpiring in the stages of lithopanspermia Ian von Hegner Aarhus University Abstract Lithopanspermia is a theory proposing a natural exchange of organisms between solar system bodies as a result of asteroidal or cometary impactors. Research has examined not only the physics of the stages themselves but also the survival probabilities for life in each stage. However, although life is the primary factor of interest in lithopanspermia, this life is mainly treated as a passive cargo. Life, however, does not merely passively receive an onslaught of stress from surroundings; instead, it reacts. Thus, planetary ejection, interplanetary transport, and planetary entry are only the first three factors in the equation. The other factors are the quality, quantity, and evolutionary strategy of the transported organisms. -

Formation of Amino Acids and Nucleotide Bases in a Titan Atmosphere Simulation Experiment
ASTROBIOLOGY Volume 12, Number 9, 2012 Research Article ª Mary Ann Liebert, Inc. DOI: 10.1089/ast.2011.0623 Formation of Amino Acids and Nucleotide Bases in a Titan Atmosphere Simulation Experiment S.M. Ho¨rst,1,2 R.V. Yelle,2 A. Buch,3 N. Carrasco,4 G. Cernogora,4 O. Dutuit,5 E. Quirico,5 E. Sciamma-O’Brien,6 M.A. Smith,7,8 A´ . Somogyi,8 C. Szopa,4 R. Thissen,5 and V. Vuitton5 Abstract The discovery of large ( > 100 u) molecules in Titan’s upper atmosphere has heightened astrobiological interest in this unique satellite. In particular, complex organic aerosols produced in atmospheres containing C, N, O, and H, like that of Titan, could be a source of prebiotic molecules. In this work, aerosols produced in a Titan atmosphere simulation experiment with enhanced CO (N2/CH4/CO gas mixtures of 96.2%/2.0%/1.8% and 93.2%/5.0%/ 1.8%) were found to contain 18 molecules with molecular formulae that correspond to biological amino acids and nucleotide bases. Very high-resolution mass spectrometry of isotopically labeled samples confirmed that C4H5N3O, C4H4N2O2,C5H6N2O2,C5H5N5, and C6H9N3O2 are produced by chemistry in the simulation chamber. Gas chromatography–mass spectrometry (GC-MS) analyses of the non-isotopic samples confirmed the presence of cytosine (C4H5N3O), uracil (C5H4N2O2), thymine (C5H6N2O2), guanine (C5H5N5O), glycine (C2H5NO2), and alanine (C3H7NO2). Adenine (C5H5N5) was detected by GC-MS in isotopically labeled samples. The remaining prebiotic molecules were detected in unlabeled samples only and may have been affected by contamination in the chamber.
