New preprint alert!!! Super proud to finally share an authentic 'tour-de-force' from the amazing PhD students Shivani Gunnan @shivanigunnan.bsky.social, Max Kotz and Lucas Ribas, in collaboration with @friedrich-group.bsky.social 👇a small thread www.biorxiv.org/content/10.6...
Developmental growth rates adapt to enable self-correction of organ morphology after injury.
Proportional organ growth requires tissue-level control of cell behavior. Yet the cues that adapt growth rates, especially after organ injury, remain unclear. Here, we uncover that developing organs a...

1/8 Breathing seems automatic. But it's a finely tuned motor behavior that has to be controlled. In this preprint, I map the circuits that match a fly's respiration to the metabolic demands of flight and mitigate the risk of dehydration. 🧵🪰 www.biorxiv.org/content/10.6...

This is extra special! First contribution from our lab and my first as last author! :-) We explore how embryos buffer cell death to ensure development under stress. If you are into cellular plasticity and developmental robustness, check out how the vertebrate retina rises to the challenge.
