This is the outcome of Leeba Chacko's PhD research - all credit to her (she also recently submitted her thesis - pictured below with her PhD hat). This work also included incredibly fruitful and fun collaborations with Hidenori (Tokushima U.), Richard (UNSW) and @wallaceucsf.bsky.social! (n/n)

The prediction of this model was that cells that lacked mitochondrial activity would grow linearly, and indeed we saw that rho0 cells (without mtDNA) switched to linear growth! (5/n)

Both the cell size and mitochondrial volume grew exponentially during the cell cycle, but given our previous data, we asked if mitochondrial activity drove the cell's exponential growth - using quantitative modeling we found this was the case. (4/n)

We compared pairs of daughter cells that divided symmetrically but partitioned mitochondria asymmetrically - cells with fewer mitochondria grew slower. Those with more mitochondria grew faster. Both daughter cells eventually divided according to the 'sizer' mechanism, but at different times. (3/n)

At cell division, small newborn cells inherited fewer mitochondria from the mother, while larger received more. But by division, all cells ended up with the same mitochondrial volume! (2/n)

How is mitochondrial volume maintained across successive generations of dividing cells? In our new preprint, we show how fission yeast cells use mitochondrial activity to control division timing and maintain mitochondrial homeostasis! (1/n)

Super excited to see all this activity on BlueSky!
👋 I'm a cell biologist/biophysicist interested in how the cell interior is organised by stochastic interactions between the cytoskeleton, motor proteins and organelles. I also care deeply about equity and inclusion in academia. 1/2

Back on Twitter (I refuse to call it the other name) after a long-ish hiatus, and a challenging 2023. Here's hoping for a happier, science-filled 2024! Cat tax:

First attempts at micropatterning in the lab - tubulin staining in HEK293 cells. Thanks to @ManuelTHERY for getting us started on this journey!

Hello world👋! I'm a cell biologist/biophysicist and my lab investigates how stochastic motor-driven processes integrate to give rise to intracellular organisation. I love all things cytoskeleton and motor proteins. I care deeply about equity and inclusion in science.

Felicity @felicitydavis2 and I have had numerous conversions in DEI (or the lack of it) in academia. Happy to see this article (with @theeliaslab) that collates our convos and provides a framework for inclusion. (1/2)

For those who didn't know, @polybiotique and I had not met in person..until yesterday! We started brainstorming 2+ yrs ago on Twitter, and worked together completely remotely to make @biaswatchindia happen. Thanks for being the best partner in crime one could hope for!

The @EMBO Workshop on Birth and Fisson of Cellular Compartments kick-started yesterday at beautiful Bilbao, Spain. Excited to finally be here for a conf that was originally meant to be held in 2020! Pic below - the Guggenheim Museum, which is a stone's throw from the venue.

After an amazing whirlwind of a networking session #EMBOYIN2022 @EMBO_YIP, I'm excited for my upcoming visit and talk at @IGCiencia on 6 and 7 June. But until then, this will be my view as I work on manuscript revisions 🤩. Thanks @NordenLab and @IGCcentrioles for hosting me!

Really excited to participate in my first Australian conference @HunterDevCell #hunter2022 with the rest of the lab! It's been lovely getting to know more about the amazing cell bio research community. @ANZSCDB

Thanking my lucky stars for friends like @polybiotique and @vaccinatedvadam. Had this handmade gift waiting for me when I got back from SF - it was a ray of sunshine on a cloudy day. Thinking of them, and my Ukrainian friends. 🇺🇦💙

So glad for this serendipitous meeting with @CytoLabKoc hours before I head back to Sydney! Always a pleasure to talk to you about science and the scientific ecosystem 😊

Excited to travel to SFO to attend #BPS22 @BiophysicalSoc annual meeting in a couple of days! My talk is part of the 'Biological Fluorescence' subgroup on the 19th at 9am. If you plan to be there, do DM/email (vaish @ - it would be lovely to catch up.

V grateful for these amazing humans (@LeebaAnnChacko, #NidaUlFatima, #GregRedpath) who joined the lab @SingMolSci at diff times this year - they've kept us going through tough times with their empathy, creativity, and infectious enthusiasm for cool science.
