It's finally here! Great start of the summer. We got our latest preprint from @chemamd.bsky.social in @qmulsbbs.bsky.social @qmulse.bsky.social, showing evidence of developmental system drift in the specification of dorsoventral (belly vs back) axis in annelids 🪱🪱🪱
#DevBio #EvoDevo

Image shows larvae of four different species of marine annelid worms, stained for muscle (magenta) and cilia (yellow). All with lateral views, with the mouth towards the left, and the future head pointing up. Images are to scale.

Very sad news, John Gurdon has died.

A developmental biologist's developmental biologist, Nobel prize winner

His work is the foundation of much of today's dev & stem cell bio.

An inspiration to many, including me. Always asking questions & wanting the answers

Happy Ctenophore Day!
These glowing ocean drifters look like jellyfish but aren’t! They’re comb jellies, shimmering creatures that light up the sea with rows of beating cilia 💙🌈
Which species can you identify? 👀 Most are raised in @pawelburkhardt.bsky.social lab

Sea urchin metamorphosis is maybe one of the most radical event in developmental biology. In just about an hour, these little pluteus larvae completely reorganize their entire body plan.

Yesterday I showed you a Gastropod larva. Today it’s the turn of another kind of mollusc, a bivalve larva! Bivalves have 2 halves, called valves, that open like a book. Gastropods, if they have an external shell, have a one-piece.
