Space missions concerned with life detection contain highly sensitive instruments for the detection of organics. Terrestrial contamination can interfere with signals of indigenous organics in samples and has the potential to cause false positive bios

Transformation of Cyanobacterial Biomolecules by Iron Oxides During Flash Pyrolysis: Implications for Mars Life-Detection Missions

Autor: Mark A. Sephton, Jonathan S. Watson, Samuel H. Royle

Publikováno v: Astrobiology. 21(11)

Answering the question of whether life ever existed on Mars is a key goal of both NASA's and ESA's imminent Mars rover missions. The obfuscatory effects of oxidizing salts, such as perchlorates and sulfates, on organic matter during thermal decomposi

High-resolution stable isotope analysis of coral skeletons is an established method to help reconstruct seawater growth temperatures for palaeoenvironmental reconstructions. Here we investigated the temperate, colonial, Mediterranean scleractinian co

Recent and sub-recent laminated tufa stromatolites can contain high-resolution δ18O records of in-stream temperature change. Fossil tufa stromatolites are therefore key targets for reconstructing terrestrial palaeoclimatic, but so far only a few exa
