I really wish there was one for tech-bio. If you don't want to run one yourself, would you mind sharing more details to help others do it? 🙏

I love this. And right now atproto is the only place you could really scale up these changes

Warsaw University Library. Has an awesome rooftop garden that's perfect for a walk while taking a break. Good napping spots and food options nearby - what else can a student dream of?

For a recent lab meeting, I wrote up a grab bag of ways to think about your development as a researcher during a PhD: emerge-lab.github.io/papers/an-un...

Sharing in case folks find it useful or have feedback!

On top of the paper, I had the pleasure of working with the incredible team at BRAID: Jan-Christian Hütter, Vladimir Ermakov, Zoe Piran, and Russell Littman on the Virtual Cell Challenge virtualcellchallenge.org/leaderboard, where our team ranked 13 on the most significant metric, PDS, and 32 overal

PerturBERT, instead, is a transformer that learns how genes co-vary under perturbation by modeling perturbation signatures. Learned gene embeddings match or outperform scGPT and other baselines despite PerturBERT training on a 30x smaller dataset and using 65x fewer genes.

Caris Completes Interim Readout of Achieve 1 Study Demonstrates Superior Sensitivity and Specificity of Caris Detect Caris Life Sciences Completes Interim Readout of Achieve 1 Study Demonstrates Superior Sensitivity and Specificity of Caris Detect

Caris is launching a WGS+ML blood test for early cancer detection. Impressive sensitivity: 56% stage 1 and 70% stage 2 - if it holds, it would blow competitors out of the water

Interesting how opus 4.6 extended and gemini 3 pro give me the correct answer here, but not ChatGPT5.2 thinking that I'd trust more with most of my work

And for a lot of Gen X journalists and academics, the answer to (a) — assuming existing skills and plans — is legit "no." AI can be useful, for sure, but the paths it differentially advantages are not the paths where they have accumulated momentum, expertise, and social capital. +

Mapping of ENSG_IDs between different release of the Ensembl database · Issue #744 · Ensembl/ensembl Dear members of the Ensembl team, I wasn’t sure who to contact, so I’m starting here. I am writing to ask you questions about the IDMapper tool presented on your website: https://www.ensembl.org/Ho...

A quick story on how we matched genes across two datasets with different Ensembl versions.
1. There must be a tool out there. Ensembl ID History converter ofc!
2. Doesn't match Ensembl search outcomes due to a bug
3. Lesson: use this client instead github.com/Ensembl/ense... !

Predicting cell state in previously unseen conditions has typically required retraining for each new biological context. Today, Arc is releasing Stack, a foundation model that learns to simulate cell state under novel conditions directly at inference time, no fine-tuning required.
