How does an embryo generate the right cells in the right place? Delighted to share our latest findings on how neural crest cells acquire vagal or trunk identities Spoiler alert: The timing & combination of CDXs preconfigures cell identity & distinct HOX states www.biorxiv.org/content/10.6...

Temporally distinct CDX programmes preconfigure vagal and trunk neural crest

Neural crest cells (NCCs) are progenitor cells vital in establishing the head, heart, gut and peripheral nervous system of vertebrate embryos. Disruptions to NCC development underlie neurocristopathie...

OK Kids, our ERK story is finally heading out into the world. After 9 years of having funding, losing funding, losing staff, getting funding, gaining staff...it's ready! We discovered a novel stage of what is an otherwise extensively studied process: how cells respond to extracellular signals. 1/n

Delighted to introduce KELPE: mESCs with two insulated genomic landing pads, which we use to generate new synNotch and PUFFFIN neighbour-labelling lines. They were named after kelpies, creatures from Scottish folklore, and they look pretty on a kelpie micropattern! #DevBio #SynBio

KELPE cells plated on micropatterned extracellular matrix forcing them to arrange in the shape of a kelpie.

KELPE: knock-in exchangeable dual landing pad embryonic stem cells enable efficient screening of synthetic gene circuits https://www.biorxiv.org/content/10.64898/2026.03.22.713470v1

Scientific journals: we don’t want you using generative AI because it makes shit up. Same journal: here is an AI summary or evaluation of this paper. This might be more useful than the actual abstract or paper that the authors freaking wrote Same journal: AI cover art which makes no sense? Oooh!

For 61 years the #BBCWorldService has been broadcasting the latest in science via its weekly Science in Action programme. That dies in the next half hour, with this final edition, reflecting on the fall in trust in expertise driven by malign interests over recent years.

It's the end of the road for BBC Science in Action. But science itself is facing growing roadblocks. For this terminal edition of SinA I'm joined by @naomioreskes.bsky.social @drdebhoury.bsky.social @michaelemann.bsky.social & @angierasmussen.bsky.social for where now? www.bbc.co.uk/programmes/w...
