We're pulling together the genomes for GlobDB release 232, which will be based on the upcoming GTDB release. We will also add new sources of genomes not in INSDC. Here's an overview of the data that will be included in the next GlobDB: globdb.org/news

Coral microbiomes as reservoirs of unknown genomic and biosynthetic diversity - Nature Reconstructing microbial genomes from 820 reef-building corals collected at 99 reefs across 32 islands throughout the Pacific Ocean highlights the importance of conserving coral reefs as vital reservo...

Now at @nature.com ! Our collab with the Sunagawa lab reveals coral reef microbiomes as a new reservoir for natural product discovery 🪸, and we functionally characterized novel RiPP chemistry and enzymology hidden within these reefs.
Congrats Daniel, Dora, Alena, and Clara on this amazing work!

So I pleased to announce the conceptual spawn of FigTree: PearTree (acronym still to be finalised). If you want to dive right in it is hosted as a web app here: artic-network.github.io/peartree (click the “Example...” button for immediate candy and then click every button you can find).

MicroSEA (Microbial Sea Eukaryotes) course is a one-week, field-based summer school to train early-career researchers in the diversity, ecology, and single-cell biology of marine protists. MicroSEA course integrates lectures, field sampling, and lab-based practicals in advanced techniques, such as flow cytometry, microscopy, culturing, and molecular analysis. The main objectives of MicroSEA course are: Fostering a deep understanding of marine protist diversity, ecology and biology; Providing hands-on training in advanced single-cell methods that are not commonly available in university programs; Building participants' confidence in designing and conducting research projects from field to data analysis; Promoting international collaborations and peer networking among students and speakers/trainers. The course will take place at the Station Biologique de Roscoff - SBR (France) - 7th to 12th of June, 2026 (arrival on the 6th, departure on the 13th). 20 participants will be selected, including 10 from EuroMarine member institutes. https://opbc.sciencesconf.org/

Protist lovers: Please apply for a week of rhapsody! Learn by doing:

Here, we nearly double the number of Asgardarchaeota MAGs, including 136
Heimdallarchaeia (49 Hodarchaeales), along with several novel lineages. We also introduce a new class, Ranarchaeia.

"By using samples collected in-situ, Weiler et al. pave the way for a practical, integrated framework for studying coral holobionts in the wild, with broader applicability to other marine holobiont systems beyond corals." @ambonacolta.bsky.social @fonamental.bsky.social

Last postdoc pub finally out!! This one was a doozy, but really enjoyable to work on. Involved some creative problem solving in regards to analysis of transcriptomic data from complex experimental designs.

In the end I learned A LOT from this team and think the final product is pretty cool.
