Great week of lab work in 🇩🇰 #Denmark, learning from Prof. Bø Thamdrup how to work with radioactive isotopes.
Many thanks to everyone at the impressive labs of #SDU – #UniversityofSouthernDenmark
It’s always a pleasure to continue collaborating with the #DeoxyMar team - to be continued!

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!

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.

Geobiology: iron, sulfur, heat – and first life
The very first cells obtained their energy from geochemical reactions. LMU researchers have now managed to recreate this ancient metabolic process in their laboratory.

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 😰
