How is developmental speed regulated ? 🪰
Happy to share my PhD story from Schweisguth Lab @devstempasteur.bsky.social. Here we show that cellular NAD+ availability and redox constrain developmental speed in the fly eye.

A big thanks to everyone involved!

Check out my first #preLight on the work of Sokol's team exploring PCP and mechanosensation! It was so much fun to pick a preprint, read it, write about it, and even get to ask the authors questions directly. I have a feeling this is just the beginning of many more preLight posts to come! 🙌
Stretch it, wound it, pull it: ADIP-Diversin polarizes anyway. Characterization of a new mechanosensitive polarity module 🐸
First #preLight from @alinegrata.bsky.social, highlighting #preprint from Chih-Wen Chu, Satheeja Velayudhan, Sergei Sokol and team:

Epithelial morphogenesis is all about how epithelial tissues develop unique shapes and structures! I'm @nehaghosh.bsky.social and will share some research in this area.

Centriolar defects underlie a primary ciliary dyskinesia phenotype in an adenylate kinase 7 deficient ciliated epithelium
The skin of Xenopus embryos contains numerous multiciliated cells (MCCs), which collectively generate a directed fluid flow across the epithelial surf…

The effector caspases drive cell death, but their activation can often be survived, so how do cells make this decision? Our new preprint from @levayerr.bsky.social shows that instantaneous caspase activity is important, but past activation has a key role to play!

So happy to share that our review on epithelial cell extrusion is out! @levayerr.bsky.social
Extrusion is such a plastic, context-dependent process, so capturing it visually in the poster that accompanies the article was a super challenging but fun task!

Just wrapped up an amazing 2-week Principles and Applications of Fluorescent Microscopy #PAFM course @pasteur.fr!
Built a microscope, designed a confocal, attended great talks, and got hands-on with the latest tech🔬💡
Great mix of theory and practice. 10/10, highly recommend!🤩

Extreme Environments: Lessons from Ocean Depths
Adaptations of the Heart: Comparative Responses to Diving and Hypoxia Across Species…Many physiological mechanisms have evolved in living organisms to cope with extreme environments, including high altitudes or deep ocean depths. These include changes in oxygen transport and utilization, metabolic adjustments, strategies to retain heat in cold conditions, adaptations to withstand high pressure, mechanisms for surviving in darkness, and efficient energy use to cope with limited food availability.
