- Scientists have found the first evidence of methane-producing microbes living outside of the deep sea. While the new findings have implications for early life on Earth, and life on Mars, they also suggest that the microbes can convert CO2 into CH4, defeating the purpose of carbon sequestration. https://news.agu.org/press-release/scientists-discover-methane-producing-microbes-in-california-rocks/ 17 comments science

- NASA rover finds no methane on Mars, casting doubt that there is any life on the planet. On Earth, life is responsible for the vast majority of the planet’s atmospheric methane. http://www.nature.com/news/nasa-rover-finds-no-methane-on-mars-yet-1.11730 38 comments science
- Methane finally confirmed on Mars. The new research doesn’t say what might produce the methane, but identifies the likely source as Aeolis Mensae, a region known to be on a tectonic transition zone. Though geological processes could be responsible, on Earth, over 90% of methane is produced by life. http://www.astronomy.com/news/2019/04/astronomers-finally-confirm-methane-on-mars 109 comments science
- The Viking landers 1 and 2 life experiments also showed a circadian rthym of 24 ish hours advancing at 2.5 minutes per day as sunset decreased with the season on mars. This lines up nicely with today's Curiosity mars methane seasonality announcement and is further evidence of both being life. http://www.gillevin.com/mars/reprint119-miller-straat-levin-final_files/reprint119-miller-straat-levin-final.htm 17 comments space

- Life on Mars theory boosted by new methane study. Rules out methane delivery by meteorites, only 2 plausible alternatives. Microorganisms are producing as a by-product of their metabolic processes, or it is a by-product of reactions between volcanic rock and water. http://www.eurekalert.org/pub_releases/2009-12/icl-lom120809.php 4 comments science
- Microbes could help future Mars explorers make rocket fuel and oxygen on the Red Planet. Researchers suggest a biologically inspired alternative that can produce both methane and liquid oxygen from Martian resources. Not only that, it could generate excess oxygen to help support human life. https://www.space.com/mars-rocket-fuel-from-microbes 4 comments space
