Congrats Gayani!!! You deserve it all and then some!

Excited to share the final published version of our work on the evolution of dorsal-ventral patterning in fins and limbs, now up on @currentbiology.bsky.social In review we added new single LARM element deletions to assess their impact on dorsality. Take a look! 🔬🧪🐟🐁 www.cell.com/current-biol...

We take for granted that our hands have two sides and can articulate in an endless number of ways. But what about a fish’s fin? Can a fish know something “like the back of its fin,” or have its future told with a fin palm reading? Check out this bluetorial to find out 👇🧪🧬🐟 doi.org/10.1101/2025...

Preprint out! Salamanders harbor a hypersensitive mTOR, thought to enable their remarkable limb regeneration. But do you need a special mTOR to regrow appendages? In Polypterus, we find that a canonical mTOR pathway supports full appendage regeneration. www.biorxiv.org/content/10.6...

Polypterids (bichirs + ropefish) are the sister lineage of all other living ray-finned fishes. Restricted to Africa today, fragmentary fossils show they inhabited South America until at least the Paleocene. Now Late Cretaceous finds add Madagascar to the list: www.sciencedirect.com/science/arti...

Late Cretaceous bichirs from Madagascar provide the first documentation of Polypteriformes (Actinopterygii, Cladistia) in Eastern Gondwana

Fossil polypterid elements have been recovered from the Upper Cretaceous (Maastrichtian) Maevarano Formation of Madagascar. These elements document th…

Regeneration of fins and limbs relies on a shared cellular playbook

The findings strengthen the case that regeneration is an old trait, offering insights into how complex tissues rebuild themselves.
