A decade ago, we had thousands of bacterial genomes. Now, we have millions. How to scale computational methods?

Our paper in @naturemethods.bsky.social answers this: use evolutionary history to guide compression and search.

Honoured and quite blown-over to receive this award. I have been, and continue to be, very lucky - first with great mentors, and then really prodigious students, postdocs and collaborators. Working with them has been a joy.

Looking for people to test the latest version of simd-sketch.

It's now 2x as fast at sketching, and supports skipping over kmers containing N and other ambiguous bases (which is only ~35% slower).

'cargo install simd-sketch' is right there under your fingertips ;)

Delighted to see our paper studying the evolution of plasmids over the last 100 years, now out! Years of work by Adrian Cazares, also Nick Thomson @sangerinstitute.bsky.social - this version much improved over the preprint. Final version should be open access, apols.

What was antibiotic resistance like before we ever used antibiotics? How did we change what antibiotic resistance genes looked like over 100 years?

Our paper looking at resistance genes from a century of NCTC historical isolates now out in mGen:

Genomic resistance in historical clinical isolates increased in frequency and mobility after the age of antibiotics
Antibiotic resistance is frequently observed shortly after the clinical introduction of an antibiotic. Whether and how frequently that resistance occurred before the introduction is harder to determin...

This is one of the findings that really motivates my research: yes, antibiotic resistance genes are ancient, but the age of antibiotics has likely contributed to a big change in their mobility and of the landscape of MGEs we see today! Very happy for Arya and to see this published.

With the addition of the soil genome catalogue, MGnify now hosts over half a million genomes - exciting milestone for the resource.
The genome catalogue for the soil microbiome is now live on MGnify! Built from MAGs & isolate genomes across 21 studies (including the recently published SMAG and Microflora Danica catalogues), it features 19,472 species.
