Genomic analyses of microbes from Canada’s Arctic provide insight into life forms that could survive on Mars. Under the permafrost of Lost Hammer Spring in Canada’s High Arctic is an extremely salty, very cold, and almost oxygen-free environment that is most similar to certain regions on Mars. So
For the first time, scientists have demonstrated that microbes found living in Canada’s High Arctic, in conditions similar to those on Mars, can survive by eating and breathing simple inorganic compounds like those that have been detected on Mars.
After extensive searching under exceedingly difficult conditions, McGill University scientists have discovered microbes that have never been identified before. Furthermore, they have obtained insight into their metabolisms by using cutting-edge genomic techniques.
To gain insight into the kind of life forms that could exist on Mars, researchers used state-of-the-art genomic tools and single-cell microbiology methods to identify and characterize a novel, and more importantly, an active microbial community in this unique spring. Finding the microbes and then sequencing theirand mRNA was no easy task. The team of McGill University scientists was led by Lyle Whyte of the Department of Natural Resource Sciences.
