Related with my last post, I entered X and found this bioRxiv preprint: doi.org/10.1101/2025...

I'm going to say some consciously exaggerated comments below.

I'm lately liking Bluesky. These ~2 months has been full of interesting papers & discussions (thanks Paper Skygest @paper-feed.bsky.social). Not crypto-bros, not so many AI-bros - just like in Twitter/X

We've been using this for years - I'm still surprised how Xist alone is so good for sex classification at single-cell level.

Credit where should be given: original idea by Daniel Fernández-Pérez (a.k.a the best postdoc!)
Excited to share that our article on accurate sample deconvolution of pooled snRNA-seq data using sex-dependent gene expression patterns is live on NAR Genomics and Bioinformatics! 🎉

Your periodic reminder that science is not done by a few selected "stars scientists". Science is done by hundred of thousands. Siloed money mean a few flashy discoveries and a lot of waste. Want to change things? Make funding accessible and stop funding calls with less than 2% success rate.

🧬 New preprint out on bioRxiv!

Using single-cell WGS and Bayesian phylodynamics, we show that some CRC tumors arise decades before diagnosis, remain indolent, then expand rapidly in the last ~2 years.

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).

It’s been a joy working with you @estellayixingdong.bsky.social!

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).
