A long time ago in a galaxy far away, there was a SARS-CoV-2 pandemic. Our paper, led by @martibartfast.bsky.social a) correcting errors in 4.5 million genomes & their phylogeny b) improving representation of the Global South in public data www.nature.com/articles/s41... (thread 1/n)

How do bacterial pangenomes evolve, what controls their dynamics, why do they exist? Fitting a mechanistic model to 450 species from allthebacteria.org suggesting fast vs slow gene exchange (i.e. amount of MGEs) is a major differentiating factor, correlated with phylogeny rather than lifestyle

New preprint from our big collaborative evolution experiment in 9 whole lakes in Alaska, written by McGill grad student @lucaseckert.bsky.social www.biorxiv.org/content/10.6... What happens if you put a mixture of multiple source populations together to complete & evolve in multiple new lakes?

How does population density affect evolutionary trajectory? Microbes construct their own niche which in turn reshapes their evolution. Preprint drop from grad student @noahhoupt.bsky.social whose evolution experiments featured blue/white colonies, 1000 generations, a lab move, and much more!

Calling all OrthoFinder users! We’ve just released GLADE, a tool to infer gene gains, losses, duplications, and ancestral genomes across a phylogeny. GLADE runs directly on OrthoFinder results. www.biorxiv.org/content/10.6... github.com/lauriebelch/... (1/10)

I was maybe 2.5 years into my position as an Assistant Professor when my phone rang, and it was Kirsty Duncan, the new federal science minister, calling out of the blue. I had never met her. She asked me what she could do for early career investigators. /1

Vaughn Cooper’s new Scientific American article offers a clear look at the potential threats posed by mirror‑life. He trained with MGI's Rich Lenski @relenski.bsky.social, whose contributions to the field are referenced in the piece. Important context for a complex topic.

Thread!

Excited to see this published! A big part of why SAR11 is so tricky to grow like "normal" microbes.

Cool study showing in exquisite details what every parent of kids in daycare already knows...

Sad to hear that Oxford Nanopore wants to discontinue the P2Solo later this year in favor of the P2i (the very pricey P2Solo that comes with a GPU to do the basecalling in it) It feels like such a big step in the wrong direction. They are a great sequencing company, not a great GPU upseller...

Montreal’s snow removal operation — snow is trucked away from streets to snow dumps — is really effective. But also *expensive*. Each centimetre collected across the city costs $1 million. An operation collecting 15 cm of snow costs $15 million. The city does it about half a dozen times a year.

First lab lunch of 2026! There’s not a lot to love about the year so far but getting to hang out with this cool gang on a daily basis keeps me going.

Peer Review is broken because a generation of Editors were trained that peer review is sacrosanct. Thus we have Editors who are clerks, sending and re-sending manuscripts to reviewers until they are happy. That's not the job. Be an Editor, not a clerk. Use your skill and judgement. Make decisions.
