James Watson, dead at 97, was a scientific legend and a pariah among his peers James Watson, the co-discoverer of the structure of DNA who died Thursday at 97, was a scientific legend and a pariah among his peers.

A Sharon Begley byline, almost 5 years after her death.

Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."

Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

That merely being “under review” by a Nature family journal is offered as a quality proxy for a paper is a tragic illustration of the extent to which academia is addicted to brands and outsources evaluation

Germinal center–mediated broadening of B cell responses to SARS-CoV-2 booster immunization SARS-CoV-2 variant booster vaccination broadens human B cell responses through the germinal center reaction.

Germinal center–mediated broadening of B cell responses to SARS-CoV-2 booster immunization

Original antigenic sin? No, memory B cells are predominantly recruited to the germinal center, where they undergo further selection and affinity maturation.

T-cell Receptor and Immunoglobulin Nomenclature Sub-Committee » IUIS Since this Sub-Committee has not addressed MHC/HLA nomenclature for several decades, the name of the Sub-Committee has been changed to “T-cell Receptor and Immunoglobulin Nomenclature Sub-Committee”…

5/6 What can we do now?
We outline strategies in the paper:
✔️ Clear, provisional reporting formats
✔️ Transparent criteria for future naming
✔️ Global dialogue to shape consensus
Let’s build something better—together.

4/6 Look up the work of the @iuis-online.bsky.social IG/TR Nomenclature Sub-Committee.
They’re urging caution and precision:
➡️ Don’t rush to name
➡️ Wait for sufficient genomic context
➡️ Use consistent interim strategies for gene reporting

3/6 The problem?
Old naming rules assumed gene order and structure were mostly conserved.
Now we know that’s not always true.
Assigning permanent names too soon could mislead downstream research.

2/6 For 30+ years, the IG/TR gene naming system worked well—standardized, community-supported, and extended across species.
But things have changed…
Genomic sequencing is exposing extreme structural variation across individuals and species.

And the second day of #ATCR25 also came to an end. Felt the meeting was a real fresh air of ideas. Super glad I joined. The best part is always to meet with old friends, and the #goodscience of course 😉
I love the location in Antwerp too 😍

Four images to illustrate some prominent single-gene myths. Top left shows a photograph of a person deftly rolling their tongue into a U-shape. Top right shows a photograph of a person’s ear, highlighting the shape and features of the earlobe and cartilage. Bottom left shows a close-up photograph of a person’s eye, with a vivid blue colouration. Bottom right shows a photograph of a person poised to write with their left hand on the blank white page of a spiral-bound notebook.

Remember when you first learned about genetics at school? All those fascinating examples of human traits that are each apparently determined by just a single gene? Time to check in on some of your favourites to see how they’re doing. 🧬🧵🧪 1/n

Cool pre-print in my feeds this morning, using a neat trick weighting TCRs by similarity prior to DGE better resolve differential usage. Seems to be a clever trick to make TCRseq behave a little more like regular RNAseq data and better use regular stats/tools:
