This is so disappointing. Fundamental **aka DISCOVERY ** science underpins training of the next generation of scientists, irrespective of if they go into translation labs or not. Failure to support it = turning off the tap. No discoveries, nothing to translate. Weak workforce #NHMRC

Shout out to a freshly minted PhD from my team 👉 @christanny.bsky.social who has presented several talks on my team’s behalf the last few months as I’ve been travelling. Watch this space for a new super star! 💫 #cytoskeleton

See this? This = implanting mouse embryo. Usually this happens inside its mother and is invisible to us, but we can actually watch implantation ex vivo with the hope of understanding why implantation goes awry in embryos of older women. A 🧵...

A mechanical origin for implantation defects in embryos from aged females Women over 35 experience a marked reduction in fertility. The origin of these fertility defects appears to reside in the implantation capacity of the embryo itself, but the mechanistic basis of this i...

First, check out my recent bioRxiv preprint w/ @oweinerlab.bsky.social: www.biorxiv.org/content/10.1...
We find contractility shifts the proportion of implantation-competent embryos from young and aged females. Keep reading this for more info!

I’m not sure as a community we **truely** acknowledged how powerful the #CellMigrationSeminarSeries series was at keeping us connected at such an uncertain time. Thank-you @ankita13jha.bsky.social @adamshellard.bsky.social @drjenmitchell.bsky.social & @simplythebex.bsky.social

I often wonder if I should post my cell migration lectures to you tube 🤔

Cell Migration Seminars Cell Migration Seminars every Tuesday at 16:00 BST.

If anyone ever wants to brush up on a lot of cell migration concepts don't forget we have several wonderful scientists who have given talks previously in cell migration seminars. I find it so comforting to go look at old videos, maybe someone else who will do as well!!

EACR Goodbye Flat Biology in Germany was fun- reconnected with old UCSF crew. Learnt some amazing science and made some new friends. One of the best cancer conferences I have attended. (Looking forward to seeing my kitties at home!).

On #worldcancerday it has been humbling to be surrounded by a truely impressive cohort of cancer scientists at @helloeacr.bsky.social ‘s Goodbye flat biology conference. We need to keep investing in research to make sure we can create impact in this space.

Have you ever wondered how microtubules withstand and respond to mechanical stress in cells?

Here we show by in vitro reconstitution assays that MAP65-1 and PRC1 promote microtubule nucleation on existing lattices, especially on those with structural irregularities linked to mechanical stress.

You asked for it! We delivered Quack-O-Grams to our members of Congress urging them to #ImpeachRFK, and get that Quack out of office!

There's still time for you to get in on this fluffy, feathery action: Send your own duck at zurl.co/W1ZnB and keep the momentum going! 🦆

🚨Great News!🚨
Our latest preprint is now live on bioRxiv!
We show that MAP65-1 and PRC1 facilitate microtubule nucleation on pre-existing lattices, particularly at sites with structural defects associated with mechanical stress.

Congrats @marianattom.bsky.social

We report the identification of the limits of microtubule self-repair and how microtubule integrity is maintained under mechanical load.
