Welcome! You are invited to join the following webinar: 2025 Westlake Science Symposia. After registration, you will receive a confirmation email with information on how to join the webinar. Ribosome heterogeneity is rapidly emerging as a transformative concept in molecular biology, challenging the long-standing view of the ribosome as a monolithic, generic protein factory. Accumulating d...

Seeing into Hi-C: How our scientific connectivity revealed the close connections in our DNA to be a work of art Scientific data can be beautiful. An example where the data itself have a particularly striking appearance even before any scientific meaning has been ascribed

I had the privilege to meet artist Mary Griffiths. Mary got inspired by Hi-C maps and over zooms we spoke about Hi-C maps, patterns and drawings. Mary’s Hi-C inspired art has been exhibited eg the Royal Academy. We wrote this piece about this art-science collaboration

Causal modelling of gene effects from regulators to programs to traits - Nature Approaches combining genetic association and Perturb-seq data that link genetic variants to functional programs to traits are described.

GWAS has been an incredible discovery tool for human genetics: it regularly identifies *causal* links from 1000s of SNPs to any given trait. But mechanistic interpretation is usually difficult.

Our latest work on causal models for this is out yesterday:

A short🧵:

Photo of a PowerPoint slide that reads: “what is ‘physiological cell biology’?” Underneath is a depiction of (left to right) gears, gears in a cell, a highlighted green cell in a liver. The corresponding words above it say molecular function <-> cellular organization <-> organismal context

Photo of a PowerPoint slide that reads “traders between simplicity and fidelity in cell biology” Underneath is a graph with simplicity on the X-axis and fidelity on y-axis. 4 points are within this space: 2D cell culture is high simplicity low fidelity, unicellular eukaryotes are high simplicity high fidelity, mammals are low simplicity high fidelity, and 3D cell culture is mid simplicity mid fidelity

First science session of #CellBio2025! 🧫🧪

Co-organized by @iaincheeseman.bsky.social and @abbybuch.bsky.social on the importance of the physiological context on studying cell biology. As a big fan of the ECM, I couldn’t agree more!

It's an amazing time to be a cell biologist, as new tech makes probing cellular processes in physiological contexts more tractable. This is the theme of a Special Interest Subgroup that @iaincheeseman.bsky.social and I are hosting at #cellbio2025. Join us on Saturday 12/5! @ascbiology.bsky.social

Ribosomal RNA (rRNA) genes are found in hundreds of copies in the human genome.

Do sequence variations in these paralogs change the ribosome function? Yes!

I am excited to share our new preprint @mbarnalab @jkpritch in collaboration with Calico:

An epic story and a must read. This is really beautiful work to understand the most amazing monthly regeneration event - menstruation. The authors reconstitute this process in mice (which don’t normally menstruate) allowing important new insights. Will also be a powerful model for future work.

Dan Jarosz becomes first senior associate dean for basic science Jarosz is the inaugural appointment to the newly created position, which will support basic science faculty throughout the Stanford School of Medicine.

Congratulations to Dan Jarosz on being named the first associate dean for basic science in the Stanford School of Medicine!

I am happy to share the latest paper from the lab. We detail a tripartite cell-free translation system based on the separation of mRNAs, ribosomes and ribosome-depleted cytoplasmic lysate from human cells, allowing for flexible reconstitution of translation reaction.

This started out as two separate projects, actually! 🤝 @mbarnalab.bsky.social has long been interested in comparing the composition of ribosomes in different parts of a cell, since localized mRNA translation is such an important aspect of gene regulation and protein homeostasis. (2/18)
