Can light build centrosome-like activity? 💡🔬 Yes! We introduce LISA (Light-Induced Spindle Assembly), now in @emboreports.org. By clustering Aurora A with optogenetics, we build centrosome-like activity that nucleates microtubules and rescues spindle defects after centrosome loss. shorturl.at/9h3VQ

Absolutely ecstatic to share that WE GOT THE COVER!!! 🥹🎉 Seeing this on NCB's cover feels surreal. So much time, science, and teamwork went into this project, and I couldn’t be more excited to see it celebrated like this. A very, very happy day for this really really old and grown embryo 🐭🧫💥

Hi! I’m @vitoryang.bsky.social, a PhD candidate studying how cells migrate collectively during development. My work focuses on cytoskeleton dynamics and Rho GTPase signalling, using Drosophila border cells as a genetically tractable in vivo model.
We are excited to invite you to the second webinar in our cell migration series. In this webinar, we focus on new models for studying cell migration with talks from @ankita13jha.bsky.social, @raphclement.bsky.social & @katrinavelle.bsky.social. More info⤵️: focalplane.biologists.com/2026/09/03/f...
