Our latest work is out in Nature today. In this paper, we introduce an improved version of NanoSeq, a duplex sequencing protocol with <5 errors per billion bp in single DNA molecules, and use it to study the somatic mutation landscape of oral epithelium in >1000 people www.nature.com/articles/s41...
Somatic mutation and selection at population scale - Nature
A new version of nanorate DNA&nbsp;sequencing, with an&nbsp;error rate&nbsp;lower than five errors&nbsp;per billion base pairs&nbsp;and compatible with whole-exome and targeted capture, enables epidemiological-scale studies of somatic mutation and selection&nbsp;and&nbsp;the generation of high-resolution&nbsp;selection&nbsp;maps across coding and non-coding sites for many genes.

Why does selection feel so weak relative to mutation in affinity maturation? A new blog post giving three perspectives, including our new transformer-based model of natural selection on antibodies: matsen.group/general/202...
The term 'affinity maturation' understates the influence of somatic hypermutation
Three recent papers quantify how nucleotide-level mutation processes drive antibody evolution.

Turns out...just like in the antibody heavy chain repertoire, germline variants in the immunoglobulin lambda and kappa loci influence the composition of light chain B cell receptors!
Way to go Eric @e-engelbrecht1.bsky.social !!!!

Germline polymorphism in the immunoglobulin kappa and lambda loci explain variation in the expressed light chain antibody repertoire
Variation in antibody (Ab) responses contributes to disease outcomes and therapeutic responsiveness, the determinants of which remain incompletely understood. This study demonstrates that polymorphism...

Trying out dplyr::consecutive_id() for a project today. #rstats

It generates a unique identifier that increments every time a variable (or combination of variables) changes.

This is a wonderful approach to an important question.
Many thanks!
Trying a slightly new model (for us at least) of #openscience. With @ronanchaligne.bsky.social and @karolisk.bsky.social, we pitted 10x Genomics Chromium GEM-X against Illumina PIPseq V head-to-head to understand these two platforms for single-cell genomics. Some thoughts off the bleeding edge: /1
