Had a lovely time at the Northern England Developmental Biology meeting on Thursday, and UK Evo Devo on Friday. Great to hear about the fascinating ongoing #DevBio research in the UK and beyond!

UK EvoDevo is happening today! We'll try to answer the eternal question, which came first the tea cup of the egg? ☕🥚 Sponsored by @biologists.bsky.social @novogene-europe.bsky.social @genewiz.bsky.social @royalsocietypublishing.org @qmul.bsky.social

Here's a tortoise embryo developing inside its egg. Check out our new article in @cp-iscience.bsky.social to learn how molecular and mechanical systems sculpt their intricate head scales 🐢🧪 www.cell.com/iscience/ful...

Exacerbated sonic hedgehog signalling promotes a transition from chemical pre-patterning of chicken reticulate scales to mechanical skin folding: royalsocietypublishing.org/doi/10.1098/... @lanevol.bsky.social‬ @rorylcooper.bsky.social‬ #OpenBiology #DevBio #biophysics

Have you noticed the rotating header images on our site? They're winners of a competition we ran in 2021. Thank you @gaparicio.bsky.social @rorylcooper.bsky.social @zebrafish007.bsky.social @ebardot.bsky.social & Markus Schliffka for the images! Give us a visit: thenode.biologists.com

ICYMI, our new work in @royalsocietypublishing.org's Open Biology shows how mechanical forces can drive patterning. By altering growth & material properties of the chicken embryo's skin in vivo, we induce a shift from molecular to mechanical patterning 🐣 🧪 royalsocietypublishing.org/doi/10.1098/...

🚨 We make the cover of Open Biology! Boosting sonic hedgehog signalling in chicken embryos flips the script of skin patterning—chemical pre-patterns give way to mechanical folding. 🧬 From Turing to tissue mechanics. 🧪 ➡️ royalsocietypublishing.org/doi/10.1098/... #shh #DevBio @royalsociety.org
