Transcriptomic diversity of amygdalar subdivisions across humans and nonhuman primates Specialized cell types and links to psychiatric disorders are revealed by genetic mapping of primate amygdala neurons.

Very excited to share my second postdoc, now out in Science Advances! We used targeted snRNA-seq to profile four major subnuclei of the primate across three species (including humans). 1/13 www.science.org/doi/10.1126/...

New work from Iva Buljan @ivabuljan.bsky.social in our lab!
We mapped how human tissue architecture changes with age using ~25k histology slides from 983 donors.
This is the first body-wide atlas of human microanatomy.

Rationalizing risk aversion in science: Why incentives to work hard clash with incentives to take risks Scientific research requires taking risks, so why does much funded scientific research play it safe? This study uses an economic contracting model to argue that this can be explained in part by the no...

3. The paper above looks at the role of "ex ante" peer review process, such as that of research grants, where results are not known at the time of review.

The paper below looks at inescapable incentive problems that arise when trying to incentivize both risk and effort.

Very proud of our paper on "scrambling-by-hopping" LADs, which was just published: www.nature.com/articles/s41.... Congrats to Lise Dauban and the rest of the team – this was a real tour-de-force!

Specialised super-enhancer networks in stem cells and neurons Super-enhancers (SEs) are clusters of enhancers with high transcriptional activity that play essential roles in defining cell identity through regulation of nearby genes. SEs preferentially form multi...

New preprint from @apombo1.bsky.social’s lab on gene regulation; insights into super-enhancers and their role in establishing complex regulatory networks of cell-type specific interactions with other enhancers and genes with specialized cellular functions 🧪🧬

(1/n) DNA-PAINT imaging inside the nucleus at single antibody resolution using TIRF? Ultrathin sectioning makes it happen!

Grateful to share my postdoctoral work introducing “tomographic & kinetically-enhanced DNA-PAINT” or in brief: tkPAINT. Out in @pnas.org!
doi.org/10.1073/pnas...
👇🧵

(3/n) Inspired by work by Eric Betzig, @heilemannlab.bsky.social, @apombo1.bsky.social and others, we adopted Tokuyasu cryosectioning to enable TIRF-based DNA-PAINT imaging throughout fixed HeLa cells without range constraint. We started with the nucleus & Pol II to explore tkPAINT’s potential.

1 month to abstract deadline for the first cell biology of the nucleus meeting at @embl.org in many years - organised by the stellar @luskinglab.bsky.social @sarawickstrom.bsky.social Tom Quail & Simone Koehler

AI, peer review and the human activity of science When researchers cede their scientific judgement to machines, we lose something important.

A few months ago, Nature published how-to guide for using ChatGPT to write your peer reviews in 30 minutes.

This is, of course, a horrible idea. Here’s my response with @jbakcoleman.bsky.social .

Big congratulations to Silvia Carvalho for successfully defending her PhD! 🎓
Her thesis focusing on SRRM2 is an exciting contribution to our understanding of gene regulation and early development.
We'd like to thank @apombo1.bsky.social for her generous collaboration during this joint supervision.

Chromatin architecture mapping by multiplex proximity tagging Chromatin plays a pivotal role in genome expression, maintenance, and replication. To better understand chromatin organization, we developed a novel proximity-tagging method which assigns unique DNA b...
