I love me some Fermi problems! However, there are no good instructions on how to use them in classes. So I wrote it up! If you read this it, you will finally learn the answer to the question 'How much phosphorous is released each day by viruses lysing Prochlorococcus cells?' tinyurl.com/2njt9r8h

Published! Using thermodynamics, we proposed a new microbial metabolism: CH4 + CO to form acetate. This reaction is exergonic under a wide range of conditions and could potentially fuel life in serpentinizing systems and the deep subsurface. agupubs.onlinelibrary.wiley.com/doi/full/10....
We’re back with a new comproportionation metabolism! Here we propose that the reaction of CH4 and CO to form acetate is exergonic could support microbial life in serpentinizing springs, the deep subsurface, and Mars and early Earth hydrothermal fluids. #geomicrobiology #astrobiology #methane 🪐🦠

Ukraine macht gleich in der ersten Zeile das Thema klar: "green into rust". Beim "great oxidation event" vor ca. 2.5 Milliarden Jahren lernten grüne Cyanobakterien, Photosynthese zu betreiben. Sie erzeugten Sauerstoff, der die Erde mit rötlichem Rost überzog, ähnlich wie am Mars heute. #ESC2026

In addition to the 2 postdoc jobs posted yesterday, we’re recruiting 2 PhD students (environmental microbiology/ molecular ecology) to join us from April. The projects will map microbial populations across niches in bioelectrochemical systems relevant to biomethanation & link them to performance.
