Planetary microbiome structure and generalist-driven gene flow across disparate habitats Microbes are ubiquitous on Earth, forming microbiomes that sustain macroscopic life and biogeochemical cycles. Microbial dispersion, driven by natural processes and human activities, interconnects mic...

In this study, we present the largest systematic analysis of microbiome structure and function, integrating 85K uniformly processed metagenomes from diverse habitats worldwide.

The team's first preprint is out!

Led by ‪
‪@vishnuprasoodanan.bsky.social‬‬ & @omaistrenko.bsky.social , we asked a question (almost) as old as microbiology: how many prokaryotic species exist on Earth? More specifically, how much diversity is "hiding" in existing metagenomic data?

A 🧵.

The rare microbial biosphere harbors many chemosensitive microorganisms undetectable by regular shotgun metagenomics. We can now explore them using our custom target-capture sequencing approach. Impressive work by
Claudia Sanchis, part of her PhD thesis!

Europe’s choice is clear.

To put science at the heart of its economy.

To become the home of scientific freedom and collaboration.

And to welcome talent from all over the world.

I’m glad to present the first elements of our Choose Europe Initiative.

Live in 2h: Metagenomic microbial strain tracking in the cloud! I'll be doing a quick demo showing how to use the SameStr workflow on the @nfdi4microbiota.bsky.social Cloud-based Workflow Platform (CloWM) - GUI / no-install / scalable / free for scientific use.

Efficient and robust search of microbial genomes via phylogenetic compression Nature Methods - Phylogenetic compression achieves performant and lossless compression of massive collections of microbial genomes, facilitating fast BLAST-like search and versatile alignment tasks.

Our latest paper, in which @brinda.eu (along with @zaminiqbal.bsky.social and others) introduces phylogenetic compression for storage and search of enormous microbial genome libraries, was published today in @naturemethods.bsky.social:

Screenshot von Google News: Zeit Online schreibt von vermeintlichem Hitlergruß, NTV sagt Geste ähnelt, SZ von möglichem Hitlergruß, Welt spricht von römischen Gruß oder Geste von Herzen

Weitere Screenshots von Google News. ZDF spricht von fragwürdiger Geste, T-Online schreibt Mast ihre Tiere mit Geste, BR schreibt von Hitlergruß ähnlicher Geste und so weiter

Weitere Screenshots von anderen Medien im selben Ton

Weiteres Screenshots, diesmal aber mit Watson, die als einziges Medium den Hitlergruß als solchen benennen

Dass nur eine einzige Redaktion sich hier traut, zu schreiben, was jeder sehen konnte: "Musk macht Hitlergruß" – das ist so dystopisch, ihr werft uns denen zum Fraß vor.

Die deutschen Mainstream-Medien sind soweit nach links gerutscht, dass sie einen Hitlergruß nicht mehr Hitlergruß nennen.

A phylogenetic approach to comparative genomics Nature Reviews Genetics, Published online: 08 January 2025; doi:10.1038/s41576-024-00803-0Controlling for phylogeny is essential in comparative genomics studies, because species, genomes and genes are not independent data points within statistical tests.…

A conserved pilin from uncultured gut bacterial clade TANB77 enhances cancer immunotherapy - Nature Communications Here, the authors show that higher levels of the gut bacterial clade TANB77 associate with better response to cancer immunotherapy, and further demonstrate in mice that a conserved pilin from TANB77 p...

I’m excited to share our new paper published in Nature Communications!
In our work, we discovered TANB77, a bacterial clade previously obscured by a polyphyletic grouping in conventional taxonomy, as a reliable biomarker across diverse immunotherapy recipient groups.

🚨 New review in @natrevgastrohep.bsky.social:
Should you take probiotics with antibiotics?
www.nature.com/articles/s41...

Bottom line: current evidence does not support the common perception that probiotics can facilitate the gut microbiome's recovery from antibiotics. BUT! 1/🧵

Today we report that an engineered skin bacterium, swabbed gently on the head of a mouse, can unleash a potent antibody response against a pathogen. Could lead to topical vaccines that are applied in a cream. @djenetbousbaine.bsky.social led the charge... @natureportfolio.bsky.social 1/55

EMBL Jobs We offer a wide range of challenging scientific and non-scientific positions at all of our European locations and encourage applications from international candidates at all career levels.

We're looking for a postdoc on the Computational Analysis of Environmental #Microbiome Data! www.embl.org/jobs/positio...
In the past two years, #EMBL scientists have gathered more than 3000 soil, sediment and water samples from Europe's coastlines within the #TREC expedition. (1/4)

The first day of our lab retreat is underway. We didn't venture far from EMBL, just up the hill to Königstuhl overlooking Heidelberg and the Rhine valley. However, we did invite guest from other labs who are working on the microbiome and are enjoying the discussions across the groups!

⚡️ Our latest preprint "Refined Enterotyping Reveals Dysbiosis in Global Fecal Metagenomes" led by @maelschermarisa.bsky.social is now available! We’ve revisited the concept of #enterotypes using a massive dataset of 16,772 human fecal #metagenomes from 38 countries! 🌍🧬 doi.org/10.1101/2024... 🧵

New paper: "Bifidobacterium and Lactobacillus Probiotics and Gut Dysbiosis in Preterm Infants: The PRIMAL Randomized Clinical Trial" showing that while the probiotics did not reduce the incidence of MDRO+, they modulated their microbiome toward eubiosis. jamanetwork.com/journals/jam... (1/2)

Most cases of siblings (90%) assigned to case/control showed spillover. Staying on the same ward was a relevant factor. bottle prep location likely also had an effect, although this was impossible to follow up

Yes we confirmed this with two methods for strain detection using SNVs on the full genome or markers, respectively. Also not merely similar probiotic. Patterns were consistent across centers in this multi center study. Not detectable in maternal samples prior to treatment
