Many people hours, calls and messages later: OSTA is now “in (pre)print”, though the real thing lives at bioconductor.org/books/OSTA.
Check it out, get in touch. We welcome any feedback, suggestions, wishes (& contributions).

This seems AMAZING: CRIPSR-All!
A preprint out today from Arc Innovation Investigator Theo Roth, Austin Hartman, Oliver Takacsi-Nagy, and colleagues introduces CRISPR All–a unified programming language for editing human cells across all major genetic perturbation types at once.

Training other methods on the same data may not be feasible due to compute limitations. Training on other much smaller data won’t be the same task. Training your implementation or with your compute limitations is not representative of the original method.

Academics also can be driven and intelligent, but the driver is often personal curiosity and understanding, with a fair bit of showing off (academic egos are something else; I am self aware enough to realise I am not immune to this though I do try to tame it).

Thread on the intellectual landscape around LLMs 👇
I love progress and am happy to see investment in it—but wonder if the amounts currently going into genAI are a missed opportunity to invest in more mundane "data plumbing" and digitalisation. Which could eventually have higher societal benefits.

I am genuinely impressed by large language models - they can absorb disparate components of text into some consolidated view, they can produce extremely good language and - with the right model - translate pretty well between languages and they are an excellent text based UI for humans to use.
