After 30 min on "nano banana" in Gemini-3 I would like to know: does BioRender have a future for plain vanilla scientific schematics? I got LLM instructions for how to write the prompt for the image below and 1.1 sec later ...

PSA: this prompt in Gemini-3 takes a zoom transcript with 12 participants and 90 min of technical discussion and in 0.5 sec converts it into 28 pages of flawlessly formatted, clearly legible, zero-reduction-of-dataset-dimensionality text. There are MANY reasons to be concerned about AI - but wow ...

Re ChatGPT in college ed. I first GSIed in 1991 at Brown and joined Berkeley faculty in 2000 - 50 semesters of teaching upper-div. The "conversations" I've had w the LLM about areas I teach in blow me away. Fellow faculty - specifically for upper-div bio we may be obsolete soon. Don't at me. Try it.

If only, if ONLY there was some method to change these newly discovered TF binding "motifs" at endogenous gene regulatory regions to see if ANY of this new phenomenology has ANYTHING to do with actual gene regulation... 1. PHE PHE SER. 2. SER MET HIS. www.nature.com/articles/s41...

A new method enables comprehensive screening and identification of low-affinity DNA binding sites for transcription factors, and reveals that nucleotides flanking high-affinity binding sites create ov...

PSA: if you're not a mouse person you may enjoy knowing that mouse Sca1 (the hematopoiesis marker) is not encoded by Sca1 (spinocerebellar ataxia 1) but rather Ly6a. I mean, OF COURSE it is. What else could it be? I'm an hg38 person and below is a self-portrait while I was figuring this out.

Here: Baby KJ at home with his mom Nicole. This really happened, folks. Hundreds of people from 8 organizations (led by Rebecca Ahrens-nicklas and Kiran Musunuru) came together to make a bespoke gene editor for this kiddo. He was once in the 7th percentile of body weight. Look at him now! ❤️

I watch my original field - chromatin and gene control - from a distance. The literature showing that so-called higher-order chromatin organization appears to have no substantial effect on gene expression grows and grows. Which is not stalling the scholars of that organization. :-) :-) :-)

#apaperaday is back from holiday. Yuzu is still with the birbsitter so a holiday picture it is. Today's pick is from @nejm.org by Musunuru et al on an N=1 case (patient with severe metabolic disease) treated by base editing (CRISPR therapy). DOI: 10.1056/NEJMoa2504747 Very good way to restart!
