New study on As uptake in pyrite, by Martin Kutzschbach et al sciencedirect.com/science/articl…

At European Synchrotron to measure Uranium XAS in calcite from Forsmark, Sweden #lnuresearch SKB

Last night in Sweden 🤩

Stargazing at Öland Island in the Baltic Sea.

I am looking for a post doc to work on microbial methanogenesis in the subsurface (note: for an application, not a position yet! deadline quite urgent). Please contact me at [email protected] and please spread the word! :)

Happy to share this recent paper on Late Cretaceous and Early Paleogene Fluid Circulation and Microbial Activity in Deep Fracture Networks of the Precambrian Basement of Western Greenland with Nick Roberts and many more agupubs.onlinelibrary.wiley.com/doi/full/10.10…

news from the depths of Greenland phys.org/news/2024-09-e…

New article by Vanessa Fichtner et al: Here we used microscale δ34S and δ18O variations of barite as an archive for fluid mixing and microbial sulphur metabolisms in igneous rock aquifers. tandfonline.com/doi/full/10.10…

Happy to share this new research paper, where we (George mostly) explore a very isolated microbial ecosystem at 975 m depth in the COSC-2 borehole, Åre, Sweden. nature.com/articles/s4200…

I have seen this news fly around the past weeks, based on a nice study by Yohey Suzuki. The news reports get it all wrong; These are not 2 billion year old microbes. They are in a vein, but the vein is not dated, so no one knows at all when life got there. popularmechanics.com/science/enviro…

Research in progress 🔬. We are measuring calcium carbonate samples from SKB site Forsmark at European Synchrotron with Ivan Pidchenko

New paper alert, Trace element partitioning between natural barite and deep anoxic groundwater...by Ferdi Kirchner et al sciencedirect.com/science/articl…

In South Africa, at Doornkop mine, level -2040 m, studying Archean gold horizons, and shatter cones of Vreedfort impact structure etc. sampling and field work w/ Axel Hofmann, Manuel Reinhardt et al. continues coming days. Vetenskapsrådet funded project deep life in deep time

First time I am taking mineral samples close to fresh hippo and elephant shit

We are looking for promising early career fellowship candidates to come and join us at Edinburgh in Astrobiology. See below for this Fellowship application details. ph.ed.ac.uk/research/resea…

New paper🚨. Here, Linnéuniversitetet Linnaeus University PhD student Femke van Dam et al report findings of methanogens deep within the Siljan meteorite impact structure. With astrobiology implications. Incl Riikka Kietäväinen link.springer.com/article/10.100…

I am happy to welcome Dr Eric Runge as new post doc in my group at Linnéuniversitetet Linnaeus University . Eric just finished his PhD at Universities of Tübingen/Göttingen and has focused on microbial biosignatures in sulfide systems on the (early) Earth. Welcome!

Today at the SIMS, with Eric Runge, and a little help from ChatGPT for the mood 😉
