I don't usually post about my day job, but the University of Sheffield is planing a restructure and compulsory staff redundancies within Chemistry. 20% of staff are under threat. You can sign an open letter opposing this decision here #SaveSheffieldChemistry

Delighted to have contributed to this exciting work led by Mikhail Tarasov and Przemysław Radwański. By combining #MINFLUX #nanoscopy with #singlechannel #patchclamp, we identified #cooperative #gating of clustered NaV1.5 #sodiumchannels. 🧵

Nanoscale organization in the cell membrane dynamically modulates the biophysics of voltage-gated sodium channels - Nature Communications
Authors show how voltage-gated sodium channels influence each other’s gating kinetics when localized in sufficient proximity to each other as part of clusters in the membrane. These nanoscale effects ...

Massive thanks to my friend Joe Austin for having me on his delightful #podcast, Rabbit Hole of Research (www.jothamaustin.com/podcast/). As a lifelong #comicbook #geek, I had a brilliant time discussing the #cardiovascular #adaptations #superheroes would need to make their powers work.

Very cool study! I suspect we're only beginning to understand the importance of communication between myocytes and the vasculature. The more we understand the better we can intercept pathological remodeling processes.
Manning & Rivera et al. (www.jacc.org/doi/10.1016/...) show that pruning just a few capillaries in the SA node plunges the heart’s pacemaker into metabolic overdraft—slowing the rate and jacking up beat-to-beat variability. The physiological equivalent of running on fumes. @jaccjournals.bsky.social
