The first version of FigTree was released nearly 20 years ago and it is still widely used (including by me). But there are currently 85 issues on the GitHub repo (github.com/rambaut/figt...) and some of them I don’t really like the look of.

Final version @nature.com of our paper describing unconventional multicellular development in a choanoflagellate inhabiting an extreme environment. A ton of new data since the first @biorxivpreprint.bsky.social preprint (which we've kept updating).

A brief 🧵 (carried over from the old place)

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:

Exciting announcement! My new department is launching a postdoc fellowship in quantitative biology. Fellows will be co-advised by two Bio faculty, one that is quant focused (not me) and one that is not (me???). I would love to co-sponsor a postdoc and build a collaboration so please reach out!

Eukaryogenesis in light of an expanded catalogue of Asgard genomes. a, Simplified, scaled timeline spanning from before the Last Asgard archaea Common Ancestor (LAsCA) to today. Thin bands mark predicted time ranges of relevant events (for example, GOE), thicker bands represent processes (for example, eukaryogenesis), and brackets indicate the period shown in b. The timeline further highlights milestones, including potential early eukaryotic fossils60 and the modern-day co-occurrence of Heimdallarchaeia and Alphaproteobacteria observed in this study (interaction likely originated earlier).

Fig. 1 | Expanded genomic diversity of Asgard archaea. a, Maximum-likelihood phylogeny based on 47 non-ribosomal markers (NM47)using the WAG + C10 + R4 model with 100 nonparametric bootstrap pseudoreplicates, including 869 Asgardarchaeota MAGs and 309 outgroup genomes. The blue branches (lower right) indicate the new Asgardarchaeota classes, Ranarchaeia, and the recently proposed Asgardarchaeia4. The concentric rings denote (in to out): the predicted genome size, metabolic guilds based on Pfam clustering, sampling locations, and black stars on the outside mark MAGs added by this study. Asgard, Asgardarchaeia; Atabey, Atabeyarchaeia; Baldr, Baldrarchaeia; Frey/Jord, Frey/Jordarchaeia; Gerd, Gerdarchaeales; Heimdall, Heimdallarchaeaceae; Hel, Helarchaeales; Hermod, Hermodarchaeia; Hod, Hodarchaeales; Kari, Kariarchaeaceae; Loki, Lokiarchaeales; Njord, Njordarchaeales; Odin, Odinarchaeia; Ran, Ranarchaeia; Sif, Sifarchaeia; Thor, Thorarchaeia; Wukong, Wukongarchaeia. b, SR4-recoded phylogeny of the same genome set inferred with the model GTR + C60 + G and 100 nonparametric bootstrap pseudoreplicates (Methods). This updated catalogue constitutes a large increase in the medium- to high-quality publicly available genomes (completeness >50% and contamination and redundancy <10%) with 65.3% from the Guaymas Basin and 34.7% from the Bohai Sea. The encircled numbers represent MAGS added by this study. The scale bars in bothsubpanels represent the average number of substitutions per site.Map created in BioRender; Appler, K. https://biorender.com/147ieoc(2025).

This is my #rstats method for standardising bar widths across different #ggplot2 plots. Seems to work for when the base of the plot is discrete, and that scale expand is not altered. If you have a go with it, let me know if it works github.com/davidhodge93...
