Announcing a new tool for "denoising" long-read amplicon sequences: savont.
Savont enables amplicon sequence variants (ASVs) directly from nanopore (or HiFi) long reads. Tested on 16S nanopore amplicons -- seems to work okay.

We just released #anvio v9, "eunice" π
This version represents over 2,000 changes in the codebase since v8, increasing the total number of programs in the anvi'o ecosystem to 176.

This symposium took place within the framework of the SALTO program, a collaboration between the Max Planck Society (MPG) and the Centre national de la recherche scientifique (CNRS). We're grateful to everyone who made this event possible.
Looking back at a highlight from 2025: Great energy at the 2025 SALTO Symposium we organized at the MPI for Marine Microbiology! Researchers from Germany, France, Spain, Portugal, and Australia joined us in Bremen to explore the evolutionary links between specialized bacteria and their algal hosts.
π The #SeqCode has reached a significant milestone: with the validation of the genus Skiveiella, a total of 1,000 #names have now been validly published under the SeqCode.
This achievement marks a major step forward in the adoption and impact of the SeqCode within the scientific community.
Our data descriptor that includes surface ocean metagenomes (with Illumina & PacBio), metatranscriptomes, and tRNAs transcripts from HawaiΚ»i is now out:

Just so you don't have to wait for our own investigations to finish. More data are here:

I knew early on I wanted to work with computers, but because of dyslexia I ended up in a lower-tier German school. The career office said a tech job wasnβt realistic. I ignored that, took a convoluted path into university, discovered bioinformatics, got hooked on algorithms&proteins, and became a PI

SingleM v0.20.2 - ONT/PacBio input reads now supported (if somewhat inefficiently), plus improved Lyrebird database for phage profiling.
Microbial fraction is now prokaryotic fraction, easier to specify input genomes.
Starting this week, I set aside one hour each week to meet ECRs outside my group who want to discuss career development, mentorship, or any non-technical professional questions.
Here is a blog that explains my motivation for this and how to schedule a meeting:

ICYMI: New online! Average nucleotide identity β the backbone of modern ecological genomics
Good luck! :)
New online! Average nucleotide identity β the backbone of modern ecological genomics
The average nucleotide identity (ANI) underpins how we map microbial diversity, compare species, and connect genomes to ecology.
I wrote a short piece reflecting on the discovery and significance of this metric (and really enjoyed digging into the context and story behind it!) #microsky π§¬
We are live from Bremen! #microsky
Two new positions are available at the MPI for Evolutionary Biology to support development of our genomics facility. Both stand to become permanent. Both offer a ton of opportunity to engage in a wide range of creative science.

I'm very happy to share that our paper describing the evolution of sex chromosomes in brown algae is out!π This project was a long journey, but it came together into a nice story 𧬠π Grateful to everyone who helped along the way!
Maybe playing with some of the statistics in CoverM (github.com/wwood/CoverM) could help you get a quick answer
Hola! agrΓ©game porfa! :)
You know sulfoquinovose (SQ)?
No?!
You should if you are interested in diet-gut microbiome π¦ π§«interactions π
SQ is a sulfosugar that this part of a ubiquitous sulfonolipid in photosynthetic organisms and thus part of your diet - if you like leafy greens and algae π₯¬
