I am super excited to share our new preprint "Contribution of ammonia oxidizers to inorganic carbon fixation in the dark ocean". This has been my absolute favorite project from my Postdoc at the Santoro Lab (UCSB) and @dome-vienna.bsky.social 🌊🦠

Contribution of ammonia oxidizers to inorganic carbon fixation in the dark ocean
Ammonia-oxidizing archaea are the most abundant chemolithoautotrophs in the ocean, comprising up to 40% of microbial cells in deep waters, and are assumed to dominate dissolved inorganic carbon (DIC) ...

A new substrate for #nitrification by #comammox microbes:
#Guanidine

Fantastic to see this published today at #Nature – great collaborative effort from our FWF Cluster of Excellence, @univie.ac.at, team Aalborg University, and Nico Jehmlich from UFZ Leipzig.

Time to upgrade your #16S_rRNA V4 primers! Goodbye Parada et al. 2018 and Apprill et al. 2015. Welcome Hu et al. 2023. Greatly improved coverage for #Patescibacteria/CPR with minimal bias on other known taxa. #MicroSky 🦠🧫 www.biorxiv.org/content/10.1...

It’s a brave new world at the @welt museum, where they’re highlighting indigenous voices and delving alternative narratives of the future. A refreshing take on how science fiction can serve as a tool for shaping future narratives.
