Great back-to-back short talks by Shayma and Eleanor PhD students in the labs of my former postdoc colleagues @kenzoivanovitch.bsky.social and @trayon.bsky.social So special to see their trainees shine! #YEN2026 @yen-network.bsky.social

Spectacular Developmental Biology Jacques Monod Conference in Roscoff. Thanks to @bardinlab.bsky.social and @lionlchristiaen.bsky.social for putting together such an exciting scientific program. And the setting was incredible too, with a beautiful sunset to end the meeting.

Our exhibit "Immortalising Natural History in 3D" will be one of of the flagship exhibits at the @royalsociety.org #SummerScience Exhibition from June 30th - July 5th! @ucl-c4ia.bsky.social @ucl.ac.uk @ucllifesciences.bsky.social with @leaveylab.bsky.social @unisouthampton.bsky.social

Such a pleasure to welcome Roser Vento Tormo @sangerinstitute.bsky.social to the LMCB seminar series @lmcb-ucl.bsky.social I have looked up to Roser since our university years in Valencia where she was a year ahead and I had to keep looking higher as she became a single cell superstar ⭐️

Gregory J. Hannon passed away in April 2026 at the age of 61. A towering figure in modern molecular biology, Greg influenced remarkably diverse areas of science. His work reshaped our understanding of gene regulation, advanced the discovery of tumor suppressors that regulate the cell-cycle machinery, and uncovered fundamental mechanisms of RNA interference. By establishing core principles of small RNA biology, he not only transformed our mechanistic view of RNA-silencing pathways but also pioneered functional genomics approaches that revolutionized basic and biomedical research in mammalian systems.

Our latest: Minimal essential requirements for neural tube self-organisation How does a single cell give rise to a tissue with the right cell types in the right proportions? We deconstruct and rebuild a self-organising tissue from first principles A thread🧵 www.biorxiv.org/content/10.6...

POINTseq, now out in Neuron after peer review. Read it. There are barcodes, viruses, and dopamine. Congrats to @hyopilkim.bsky.social on leading our lab's first published paper!

🧬🧬🧬 Join us this Wednesday, June 3rd for exciting talks from three early career chromatin/transcription researchers: Mark Geisler, @jcornwallscoones.bsky.social, and @sidujain.bsky.social! register here: us06web.zoom.us/webinar/regi...

The reliable generation of diverse cell types in precise proportions is essential for the formation of functional tissues during embryonic development. Three-dimensional organoid models derived from p...

Kim et al. introduce POINTseq, a high-throughput barcoded connectomics method for mapping brain-wide single-neuron projections of a specific cell population defined by common viral-genetic tools. Applying POINTseq to mouse midbrain dopamine neurons reveals diverse connectomic cell types and stereotyped collateral wiring patterns that may underlie distinct dopamine functions.
