About Exobiology: The Case for Dwarf K Stars [PDF]
, 2016 One of the most fundamental topics of exobiology concerns the identification of stars with environments consistent with life. Although it is believed that most types of main-sequence stars might be able to support life, particularly extremophiles, special requirements appear to be necessary for the development and sustainability of advanced life forms.

Cometary panspermia explains the red rain of Kerala [PDF]
arXiv, 2003 Red coloured rain occurred in many places of Kerala in India during July to September 2001 due to the mixing of huge quantity of microscopic red cells in the rainwater. Considering its correlation with a meteor airbust event, this phenomenon raised an extraordinary question whether the cells are extraterrestrial.

Searching for Life on Habitable Planets and Moons [PDF]
J.Cosmol.5:801-810,2010, 2009 Earth is the only known inhabited planet in the universe to date. However, advancements in the fields of astrobiology and observational astronomy, and the discovery of large varieties of extremophiles with extraordinary capablities to thrive the in the harshest environments on Earth, have led to speculation that life may be thriving on many of the ...

Frontiers in MicrobiomesOceanic hydrothermal vent systems represent some of the oldest habitats on Earth and serve as analogs for extraterrestrial environments. The Lost City Hydrothermal Field (LCHF) near the Mid-Atlantic Ridge is one such environment, and its large chimneys ...

Archaea-based Microbial Fuel Cell Operating at High Ionic Strength Conditions [PDF]
arXiv, 2011 In this work two archaea microorganisms (Haloferax volcanii and Natrialba magadii) used as biocatalyst at a microbial fuel cell (MFC) anode were evaluated. Both archaea are able to grow at high salt concentrations. By increasing the media conductivity, the internal resistance was diminished, improving the MFCs performance.

Amino Acid Distributions and the Effect of Optimal Growth Temperature [PDF]
arXiv, 2013 We perform an exhaustive analysis of genome statistics for organisms, particularly extremophiles, growing in a wide range of physicochemical conditions. Specifically, we demonstrate how the correlation between the frequency of amino acids and their molecular weight, preserved on average, typically decreases as optimal growth temperature increases.

Habitability in the Solar System and New Planetary Missions [PDF]
arXiv, 2013 Definition of habitability depends on the organisms under consideration. One way to determine habitability of some environment is to compare its certain parameters to environments where extremophilic micro-organisms thrive on Earth. We can also define more common habitability criteria from the life as we know it.
