Causal Discovery from Conditionally Stationary Time Series Causal discovery, i.e., inferring underlying causal relationships from observational data, is highly challenging for AI systems. In a time series modeling context, traditional causal discovery methods...

I was at the Symposium on Causality in Biology & AI in Barcelona. I presented a flash talk on inferring time-varying gene regulatory networks from time series scRNA-Seq data.

Some results here - arxiv.org/abs/2110.06257

This is not a HiC map! Ever wondered if multiple enhancers get activated simultaneously? We measured chromatin accessibility on thousands of molecules by nanopore to create genome-wide co-accessibility maps. Proud of @mathias-boulanger.bsky.social @kasitc.bsky.social Biology in the thread👇

Very cool tool name!

🤝 It was a real joy to reconnect with my PhD supervisor and mentor @gjbarton.bsky.social, as well as former colleagues
@stuartmac44.bsky.social, @foreveremain.bsky.social, @mitsenkov.bsky.social, Vanessza Fentor, Douglas Freeburn,

Update: Our paper on "Causal Discovery from Conditionally Stationary Time Series" was presented two weeks ago at ICML 2025!

One thing that really bothers me with the new "virtual cell" terminology is that it is currently largely focused on a very narrow definition of models that can predict effects of trans perturbations (gene dosage, drugs etc) on gene expression. 1/

We released our preprint on the CREsted package. CREsted allows for complete modeling of cell type-specific enhancer codes from scATAC-seq data. We demonstrate CREsted’s robust functionality in various species and tissues, and in vivo validate our findings: www.biorxiv.org/content/10.1...

🚨New pre-print on Biorxiv! 🚨

Histone modifications are measured with ChIP-Seq, but the chromatin landscape introduces biases. We introduce DecoDen to simultaneously learn shared chromatin landscapes while de-biasing individual measurement tracks.

Digital sovereignty – Huber Group @ EMBL The US is now a mafia-style extortionist you want to stay away from

It's time for individuals and organizations in Europe and other democratic countries to move mission- or life-critical IT services and infrastructure outside the reach of the US government; noting that US tech companies have already largely subordinated themselves.

Three AI-powered steps to faster, smarter peer review Tired of spending countless hours on peer reviews? An AI-assisted workflow could help.

Let's talk about this Nature piece in more detail.

I've rarely read something so anti-scientific anywhere short of the National Review.

I've been developing a semantic search tool that covers not just bioRxiv and medRxiv, but the entire PubMed database. This means you can search across a massive collection of biomedical research using keywords, questions, hypotheses, or even full abstracts. Try it out: mssearch.xyz

(1/4) Thrilled to announce another major release of the HOCOMOCO motif collection, well-known for its silly name and rigorous approach to constructing and benchmarking DNA sequence motifs recognized by human and mouse transcription factors.

What's Happening Inside the NIH and NSF

A long post about what’s happening to the science funding agencies in the US and why. As mentioned, this one just kept getting longer even as I kept stripping curse words from it.

How should the advancement of large language models affect the practice of science? | PNAS Large language models (LLMs) are being increasingly incorporated into scientific workflows. However, we have yet to fully grasp the implications of...

An LLM "creates textual claims, and then predicts the citations that might be associated with similar text. Obviously, this practice violates all norms of scholarly citation.

At best, LLMs gesticulate toward the shoulders of giants."

High content of nuclei-free low-quality cells in reference single-cell atlases: a call for more stringent quality control using nuclear fraction - BMC Genomics The advent of droplet-based single-cell RNA-sequencing (scRNA-seq) has dramatically increased data throughput, enabling the release of a diverse array of tissue cell atlases to the public. However, we...

Not checking nuclear markers like MALAT1 or intronic reads in your scRNA-seq data?🚨
We show their power to flag low-quality cells—even in top public datasets. It’s time to prioritize better QC for cleaner, more reliable genomics research!

ChIP-DIP maps binding of hundreds of proteins to DNA simultaneously and identifies diverse gene regulatory elements - Nature Genetics ChIP-DIP (ChIP done in parallel) is a highly multiplex assay for protein–DNA binding, scalable to hundreds of proteins including modified histones, chromatin regulators and transcription factors, offe...

Gene regulation involves thousands of proteins that bind DNA, yet comprehensively mapping these is challenging. Our paper in Nature Genetics describes ChIP-DIP, a method for genome-wide mapping of hundreds of DNA-protein interactions in a single experiment.

We need Epigenetic Hulk here.

Something that's been bugging me for a while in bioinformatics data analysis is this overreliance on packages, workflows and what's been called "cargo cult science".

Can we have more conceptual thinking, more theory?
Asking for what we really want to achieve and what we need to do gets us there.

Thrilled to announce Boltz-1, the first open-source and commercially available model to achieve AlphaFold3-level accuracy on biomolecular structure prediction! An exciting collaboration with Jeremy, Saro, and an amazing team at MIT and Genesis Therapeutics. A thread!
