Nitrobacter NOB respond to environmental conditions by modulating their nitrite affinity, which highlights the importance of pre-culturing on experimental observations.

Minute witnesses from the primordial sea Researchers at ETH Zurich have been able to measure - for the first time - how the amount of dissolved organic carbon in the sea has changed over geological time. The results reveal that our explanati...

Very cool write-up by @ethz.ch on our recent paper in @nature.com on reconstructing dissolved organic carbon in the ocean through geologic time! Led by Nir Galili @eth-eaps.bsky.social

This thread is a delight.

Really glad to announce a new preprint from our lab: Global distribution of quinones in Bacteria! We here combine comparative genomics and text mining to leverage information on quinones distribution from thousands of articles describing new species and from dozens of thousands of genomes! 1/5

I'm looking for a driven PhD student to join us at @au.dk and to both generate new paleoclimate data in the lab and work on computational problems to understand climate relationships across timescales.

Get in touch if you'd like to hear more, and apply by Nov 1!

Variation in the biomass of metazoans and their biodiversity across the Phanerozoic

An assumption we long had in Earth Sci was that, in the geological past, more diversity meant more life in general. Someone finally got around to checking that, and it works! Biomass patterns follow the biodiversity curve. 🧪⚒️

🚨 Imagine a bacterium that refuses to follow the textbook:
It grows as tangled filaments, divides unevenly, reshapes its own membranes… and even builds grappling hooks.
Meet Litorilinea aerophila — and here’s why it blew our minds.

Open position for PhD student / Postdoc in biogeochemistry For a fully funded four-year project exploring environmental and ecological dynamics in the Mediterranean and Red Sea, we seek a top tier PhD student or postdoc. The project aims to understand the formation and persistence of biodiversity hotspots, especially in light of global climate change and local stressors. The ultimate goal is to gather insights across different organizational levels, from molecular, organismal, and community to habitat structure and biogeochemical pathways, in order to construct comprehensive models that forecast the future dynamics and fate of these ecosystems under changing conditions. This position would be focused on a key aspect of this project – the variability of seafloor fluxes and their interaction with the microbial community to facilitate the habitability of shallow (up to 40 m) and mesophotic (up to 200 m) biodiversity hotspots such as reefs. Interested candidates, please contact by email Dr. Or Bialik (obialik@ocean.org.il) or Prof. Eyal Rahav (eyal.rahav@ocean.org.il) with a letter of motivation, CV, and contact details of at least one referee for this post not later than the 28th of August 2025.

I have a fully funded open #position for a PhD student/postdoc in marine #biogeochemistry. As part of the MARBEDS project, we are seeking someone to study seafloor fluxes and their interactions with microbial communities in biodiversity hotspots.

I have some ideas, but what solutions are people using? Any good recommendations or things to avoid?
