Super excited and thrilled to see this work come out in Nature today. 🥹@tdcapellini.bsky.social Thank you so much for your amazing mentorship throughout the project, and to all my co-authors who helped take this work to the next level.

Thrilled to have co-written a News & Views with P. Janvier on Haridy et al.’s recent Nature paper. They reveal that Anatolepis, once thought to have the oldest dental tissue, is actually Cambrian arthropod sensory armor!
Paper: nature.com/articles/s41...
N&V: www.nature.com/articles/d41...
The evolutionary origin of sensitive dental structures
Fossil data shed light on a debate about when vertebrate dental tissues arose by assigning an early sensory structure to arthropods rather than to vertebrates.

When did synovial joints evolve? @neelimasharma.bsky.social @neilshubin.bsky.social &co reveal that stable, mobile & lubricated joints were present in the common ancestor of jawed fishes but lacking in jawless ones 🧪 @plosbiology.org plos.io/3CTC8La
Top: Immunostaining reveals aggrecan (yellow) at the articular surfaces in the pelvic joint of an embryonic little skate (stage 33). The nucleus is stained using DAPI and is shown in red. Bottom: Phylogenetic tree adapted from Donoghue and Keating, annotated to show that synovial joints exist in extant jawed vertebrates (gnathostomes), but the study’s results do not support their existence in cyclostomes. The presence of reciprocally shaped and cavitated joints in the dermal skeleton of antiarchs suggests that joints that function by relative sliding (similar to synovial joints) first originated in stem gnathostomes.

New paper led by @neelimasharma.bsky.social on the lab! The evolutionary origin of highly mobile joints!

@philipcball.bsky.social gets a bit spicier in places than I did, "it can be hard to avoid the suspicion that sometimes its (omics data) collection serves to postpone the awkward time when some sense must be made of it all."

And I like it :)

Ever wondered how your #genes know when to turn on or off? 🧬🔌 In our latest #BioBasics episode, @juliannahaug.bsky.social, a researcher in the Sauka-Spengler Lab, explains gene regulatory networks — the circuits that control gene activity.

Gene editing technology began by people studying salt marshes. Ozempic began by folks studying the venom of Gila Monsters. Support for basic science has empowered us to understand our world. Tethering it to applications health has transformed and saved countless lives.

"Imagine a DAPI-like stain, but for the extracellular matrix." That's basically how this work was pitched to me by Kayvon and Antonio a year or so ago. Now the final product really delivers. Read about their versatile label for ECM in living tissues here: www.nature.com/articles/s41...

We are excited to share our work on molar #evodevo 🦷 in mouse and hamster 🐁, led by the amazing team of Marie Sémon and Sophie Pantalacci. We find an inverted hourglass pattern, with a maximum of evolutionary divergence at the bell stage.
https://www.biorxiv.org/content/10.1101/2025.01.23.634446v1
Top: hourglass pattern of increasing then decreasing divergence over molar development, with the stages BUD, CAP, BEL (maximum divergence), DIF and SEC. Bottom: illustration of gene processes influencing this pattern, from left to right: image of embryo with “shared: limbs, scales, glands; lung, kidney”; “immunity genes (influx of blood)”; image of embryo and of tooth with “shared: secretion; intrinsic: mineralisation”.

I am very proud of the work that went into this new Sanger Lab publication. This paper was led by postdoc Marta Marchini and a number of my lab's undergraduate students, each of which contributed unique skills or effort to the completion of this project.
