Antarctic Soils

Researchers from University of Chile found that the Pseudomonas bacteria, one of the predominant bacteria groups in the Antarctic Peninsula, can be a source of 'resistance genes'. These bacteria are said to carry natural antibiotic and antimicrobial resistance and have the potential to spread out of the polar regions.

Can not finding signs of life at a place on Earth that closely resembles the area on Red Planet a bad news for those trying to find life on the Martian surface? Yes, say researchers, suggesting that the failure to find active microbes in the coldest Antarctic soils on Earth has implications for search for life on Mars.

Deepening suspicion that there is or was life in Mars, a study based on images and data captured by the NASA rover Curiosity says that Mars had Earth-like soils comparable with soils in Antarctic Dry Valleys and Chile's Atacama desert some 3.7 billion years ago.
