It was an awesome day of Aurora and MPS1 discussion! Good luck with the fabulous discoveries!

Opinion | We Ran the C.D.C.: Kennedy Is Endangering Every American’s Health

9 CDC Directors going back to 1977 speak out. What RFK Jr has done to our nation’s public health system "should alarm every American."

It "is unlike anything we have ever seen at the agency, and unlike anything our country has ever experienced." www.nytimes.com/2025/09/01/o...

Wonderful work by @viji-draviam.bsky.social and team.
Congratulations on the publication!

We're honored to be cited in your work—exciting to see our contributions supporting cutting-edge research. Looking forward to following your continued discoveries!

Thanks to the infrastructure and technician support by @qmulse.bsky.social and @qmul.bsky.social.

Fluorescence recovery in the super-resolution regime reveals subcompartments of 53BP1 foci Wu et al. exploit 60 nm lateral resolution of diSIM/SIM2-processed super-resolution (SR) images to develop FRAP in the SR regime, which reveals distinct types of DNA-damage-repair-associated 53BP1 foc...

FRAP-SR (60 nm) reveals subcompartments within DNA damage repair foci in live cells. FRAP in the Super-resolution regime is likely to transform many other fields of cell biology: www.cell.com/cell-reports....

Crossover patterning through condensation and coarsening of pro-crossover factors Nature Cell Biology - Zhang et al. provide evidence that, during meiosis, recombination proteins assemble into active droplets, the coarsening of which partially explains the phenomenon of...

Very happy (and frankly relieved) to see this paper finally out in peer-reviewed form. (Preprint was posted in August 2021, but this is the world we live in now). rdcu.be/erMk6

Still thinking about my great experience at #Biologists100 — from my flash talk and poster, to the ECR session and insightful main talks, and all the chats in between!

Big thanks to @biologists.bsky.social & @bscb-official.bsky.social for the opportunity!

A noncanonical role for dynein in controlling microtubule growth in mitosis, as shown previously in interphase. More here: www.biorxiv.org/content/10.1... Dynein synergises with EB1 to facilitate cortex-microtubule encounter and proper spindle positioning in metaphase. Thanks to the funder @ukri.org

'Science is an investment' - long term and for all. Very glad to see extra funds towards scientific excellence!

FRAP-in-SR: Fluorescence recovery in the Super-Resolution regime reveals subcompartments of 53BP1 foci We combine Lattice Structured Illumination Microscopy (diSIM/SIM2 with ~60 nm resolution), Lattice Light-sheet microscopy and Fluorescence Recovery After Photobleaching (FRAP) to explore 53BP1 dynamic...

FRAP-in-SR for dynamic studies at 60nm resolution!! If you explore cell cycle, DNA damage or 53BP1, here are new tools for live-cell microscopy: a fruitful collaboration with @carlzeissstiftung.bsky.social for SIM2/diSIM and @rappopto.bsky.social for localised FRAP www.biorxiv.org/content/10.1...

We are looking forward to meeting everyone in Liverpool next week for our special 100-year anniversary conference. We have a busy, fun-filled programme. You can follow all the action from Biologists @ 100 at #biologists100. 100yearsconference.biologists.com

Now seems a good time to mention that I haven't yet filled a postdoc position in phylogenetic methods. If you just lost your job, need something temporary, and know something about bioinformatics/statistics/evolution, talk to me.
