Back on land after the #DeoxyMar expedition.
Real pleasure to work as Chief Scientist aboard the #RV_Aurora alongside Captain Torben Vang and his excellent crew.
Grateful as well to the brilliant team of scientists from #Germany, #Denmark and #Sweden - can´t wait to start diving into the data!

Open PhD position in my group to start relatively soon:
Deadline to apply: 31.08.2025
Thanks for sharing!

Researchers at #LMU, led by William Orsi, simulated ancient hydrothermal systems in the #lab. The archaeon 'Methanocaldococcus jannaschii' grew without added nutrients, using hydrogen from iron-sulfur reactions—possibly mimicking early life on Earth.

Great work from Ömer Kürşat Coskun, postdoc of my #EmmyNoether group, together with William Orsi and Steven D'Hondt.

Organosulfur compounds play a key role in marine sediments worldwide. In this study, we combined qSIP and GC-QMS to identify active uncultivated microbes driving organosulfur cycling from taurine and methionine. The open-access pdf can be downloaded here:

Back in 2019 we screened an obscure lineage of bacteria for a side project and noticed something quite unusual. A quinone, used in cellular electron transport, that looked similar to the type used by plants and algae to perform photosynthesis.

Extreme temperature anomalies in the high Arctic continue. It’s mid-winter & it’s 4°C 🌡️
On a normal year we commonly have temperatures down to -20°C & a thick snowpack ❄️
But this winter the northernmost settlement in the world is a melting ice rink & snow on the tundra is vanishing before our eyes 😰

Two weeks left on our cruise to the Oxygen Minimum Zone off the coast of Chile... content is coming out! Cameos from Laura Bristow, Osvaldo Ulloa and Chief Scientist Maria Pachiadaki (@microbiaki.bsky.social) www.youtube.com/watch?v=fGi6...

If you work on interdisciplinary approaches connecting biogeochemistry, ´omics and modelling, you are welcome to our session at #Goldschmidt2025 in Prague.
Abstracts submission deadline: February 26th.
