Bsky is, believe it or not, still the place to be. The mood has shifted, sure. Scientific X is gone -- remember its algo sinks posts with links, so effectively you can't share articles there.

What explains the difference in conclusions between Scale AI / Secure Bio and Active Site? Different lab flows being assessed, or a hint of incentives and selection bias?

I'll give a webinar talk April 24th, covering: - nf-core/proteinfold (AlphaFold2, ESMFold, etc.) - Molstar/Mol* - what comes before and after them This kicks off a series on molecular modeling using open-source tools on DNAnexus.

I wrote about how I write code for clinical use, as of 2026: etal.github.io/2026/03/30/v... Briefly: - Claude Code in one terminal, zsh in another - Papers and docs in a browser - Plugins: feature-dev, serena, python-lsp, explanatory-output-style - Lots of deterministic tools.

Gut feeling: AAV is probably out aside from what is already at the clinical stage in pipelines; LNP with various payloads is probably the future, and there might be a lull in between while scientific gaps get figured out.

To be fair, there was some chicanery and sloppy work happening under LDT's lighter scrutiny, per @annaleighclark.bsky.social
000
Eric Talevich @etalevich.bsky.social · 31/03/2025
Whereas, the LDT route allows easier commercial ramp-up from research use only (RUO) to CAP/CLIA-certified lab-developed tests (LDT), requiring technical/analytical validation of the new test on banked samples but not patient recruitment. Faster, less overhead, lower reimbursement. Stepstone to IVD.

Eric Talevich @etalevich.bsky.social · 31/03/2025
The rule was seen as unfair by both academic medical centers and biotech startups because it would have essentially required a clinical trial to bring any new test to market. Only the biggest existing players can afford to do that, and it takes a long time to build up to that point.

A district court has struck down the FDA's Final LDT rule, which would have required clinical test developers to navigate full FDA IVD approval to bring new products to market -- a much tougher bar to clear. Tl;dr: Diagnostics biz isn't dead. Source: www.courtlistener.com/docket/68802...

Element Bio says this on-instrument hybrid capture approach can bring total library prep time down from 12-24 hours to as little as 5 hours (before sequencing). That faster TAT should be great for NGS diagnostics.

It's critical to 1. choose the right market, and then 2. bring a working product to that market, in the right way, considering pricing and reimbursement. For GT in particular, patients sometimes hold out because you usually only get one shot at a cure.

Scientifically, there's some bitter irony there because CRISPR gene therapies / gene editing therapies "ought" to be able to anything a cell therapy can do, but more directly. But they're not ready yet.

Eric Talevich @etalevich.bsky.social · 17/03/2025
Cell therapies, on the other hand, might actually be doing OK. For example: www.biopharmadive.com/news/astraze... Maybe the clinical endpoints are more compelling in cancer and autoimmune diseases. Maybe the tech just works better.

E.g. say you have an in-house notebook that supplements the NGS analysis you get from laava. You decide during development that you'd like to copy in one of laava's plots and maybe tweak it. With Quarto that could be a more seamless copy-paste, versus Jupyter <> Rmarkdown.
000
Eric Talevich @etalevich.bsky.social · 12/03/2025
The reporting mechanism would also benefit from using Quarto. I have various notebooks to create plots using both Python and R from the same LAAVA output data, and while Jupyter and Rmarkdown can be multilingual, for the purpose of generating and remixing visual reports, Quarto handles it better.

Ideally I'd translate the Bash scripts to Python, convert it all into a proper Python package, and refactor. But modern Python packaging handles CLI scripts in a quirky way that I worry might harm the experience for developers who wear other hats most of the time. Still worth doing, but not today.

Eric Talevich @etalevich.bsky.social · 12/03/2025
The motivation for making it modular and easy to modify is that some parameters deserve studies to tune properly, particularly the read mapping parameters. Even the choice of minimap2, bowtie2, or maybe megablast is worth evaluating.

Eric Talevich @etalevich.bsky.social · 12/03/2025
I focused on the developer experience in this release. The codebase now supports multiple entry points fairly smoothly: portable Nextflow, Form Bio GUI, docker image, a Bash script mirroring each process in the workflow, and a Python quasi-package (with room for improvement).

How I pick a bioinformatics tool to start: - Check nf-core -- is there a pipeline I can use as-is? If not, what tools are used inside other relevant pipelines? - Check the methods of studies similar to what you're trying to do -- not searching methods papers themselves initially, but who used them

There is some ancient wisdom about never coding at the limit of your own cleverness, because modifying that code will require you to be twice as clever. AI doesn't care. You can go from idea to usable app to unmaintainable legacy codebase in minutes/hours, rather than months/years.

Eric Talevich @etalevich.bsky.social · 09/02/2025
For scientific code, we're hosed because the whole point is to do something that's never been done before. Libraries are good enough that the new code is close to declarative. That means we're stuck with the older approach (thinking & looking up error messages).
000
Eric Talevich @etalevich.bsky.social · 09/02/2025
Use the most common and stable frameworks, basically just JS/Node, Python, and Java, because that's most of the training data. Major API changes between versions confuse the AI. (This means scientific computing is inevitably in the danger zone. Nextflow, yikes.)

Eric Talevich @etalevich.bsky.social · 09/02/2025
Agentic AI coding is leading to some new software development best practices: Keep projects small and modular to fit within the context window. Start with a good PRD. If the initial architecture is wrong, just start over. Use distinct, unambiguous names or the AI will get confused.

For compbio in particular, so much of it is done for free in the public interest -- e.g. NCBI/EBI/DDBJ provide platforms, no? We commoditize eagerly. And I see AWS et al. expanding into this area partly because the barriers are so low.

Extraordinary. You answered most of my questions in footnote 4. If we follow the money: Clinical development, sales, and marketing are where pharmas spend real money, right? Clinical research orgs (the other CRO) e.g. IQVIA, Paraxel, Icon, are not platform companies, but they toy with the idea.

The fast, proprietary reimplementations are popular for "production at scale" use cases e.g. NGS diagnostics. You can prototype with OSS tools, then swap in Dragen/Sentieon/Parabricks equivalents to save time and compute costs, even after licensing.
