Discovery of Naturally Etched Fission Tracks and Alpha-Recoil Tracks in Submarine Glasses: Reevaluation of a Putative Biosignature for Earth and Mars

International Journal of Geophysics, 2016
Over the last two decades, conspicuously “biogenic-looking” corrosion microtextures have been found to occur globally within volcanic glass of the in situ oceanic crust, ophiolites, and greenstone belts dating back to ~3.5 Ga.

Analytical Chemistry in Exobiology

Biological Sciences in Space, 1988
Recent and scheduled chemical analysis in space missions are reviewed. Recent progress in analytical chemistry have made it possible to analyze chemical cpmposition of extraterrestrial samples in space. VEGA-1 and Giotto utilized mass spectrometers to analyze cometary dust particles. Phobos I and II are flying toward Mars and its moons.

First record of multicellular filamentous benthic bacteria from freshwater lagoons in central Chile

Gayana
Observations on “macrobacteria” inhabiting the reduced bottoms of two freshwater lagoons in central Chile are here presented. The new finding of morphologically diverse, colorless multicellular filamentous bacteria expands their known presence into ...
