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)

We're disappointed to see Ben Barres's powerful book "The Autobiography of a Transgender Scientist" among the ~400 titles removed from the Naval Academy Library. Needless to say, we're proud to have published his book and will keep it — and his memory — alive.
The Coming Out of a Transgender Scientist
"I know that I am making the right decision because whenever I think about changing my gender role, I am flooded with feelings of relief."

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)

In summary, we demonstrate a central role for mitochondrial activity in dictating cellular growth rates/kinetics and ensuring mitochondrial volume homeostasis. (6/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)
Plot of cell size over time, fit to an equation that links cell size to mitochondrial activity.

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)
comparison of daughter cell pairs with similar cell sizes at birth but asymmetric mitochondrial partitioning, showing that the daughter cells with less mito grow slower and take longer to achieve the size for division.

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)
Plot of mitochondrial volume at division against cell length at birth, showing a linear scaling of mitochondrial volume with cell length Plot of mitochondrial volume at division against cell length at birth, showing all cells have roughly the same mitochondrial volume at division.

Posting this here now that the orange man has erasing scientific literature. What people, perhaps without any strong opinions on this, never understand is the barriers that academics have to overcome to publish papers on gender and trans identities.

He can burn the journals, but we will keep PDFs 😘

It feels like such irony when a group of us were writing this article to Cell, and were told by the American higher-ups of the journal to soften the language. e.g. we were asked to omit the word, "radical" which appeared once in the paper just so it won't offend any one. That was <12 mths ago.

Aaaand that’s a wrap at Asia Pacific Microscopy Congress 2025 in sunny Brisbane, attended by a big team from Single Molecule Science. Lots of exciting new 🔬 tools and translation in biomedical investigations. @ijayas.bsky.social @arindam92.bsky.social

Reading the paper in Cell about how to close the scissor plots in gender representation at senior academic positions, I feel just a touch of pessimism. Having reached a level of seniority (middle management) I didn’t think I ever would, I read these great ideas wanting more, much more /1.

Gender inequality in STEM fields remains pervasive and undermines the ability for talented individuals to excel. Despite advances, women still encounter obstacles in pursuing academic careers and reac...

My lab at UMass Chan Med School uses a variety of approaches to elucidate the molecular mechanisms of membrane traffic. Striving to make academic science a more diverse, equitable, welcoming and inclusive place. Incoming President for the American Society for Cell Biology (ASCB)! Opinions are mine.

I am delighted to share our new preprint in which we reveal the crucial role for mechanical forces in myoblast fusion. Great work from Yoann, Sushil and Aleksandra and great collaboration with Christophe Marcelle and Amin Doostmohammadi!

Non-native English speakers need 50% more time to write a paper

When they do, they face a 2.5 times higher chance of being rejected because of language
