Sanja skeletonised all the 853 muscle cells in the larva and annotated their desmosomes and the partner cells and extracellular structures that the desmosomes attach to. This resulted in a single network of over 2,000 cells and extracellular structures (basal lamina, chitin endoskeleton etc) that we call the desmosomal #connectome. In synaptic connectomes the links are formed by #synapses, in a desmosomal connectome the links are desmosomes.
The revised version of our paper on the desmosomal #connectome of the #Platynereis larva is now out

Our new preprint on the deeply conserved structure, and evolution, of insect Gustatory and Odorant receptors. The plethora of chemosensors in insects may be the result of extreme and rapid diversification of a single branch of a diverse superfamily of Eukaryotic (including human!) receptors, dating to at least LECA. An exceptionally fun collaboration with @bentonlab@twitter.com come to fruition! https://doi.org/10.1101/2022.12.13.519744

Finally taking the time for an #introduction on #mastodon !
I'm a #marine #microbiologist currently leading a #lab at the #EMBL #Heidelberg. My lab is fascinated by the #diversity & #impact of #microbial #interactions across #biological scales, with a particular focus on #eukaryotic #phytoplankton. We think about #symbiosis #epibiosis #viralinfection #singlecell #ecology, often wt #TaraOceans folks⛵
I push for #inclusive #science, and to rethink our #practices in light of #sustainability 🌊

Ok, my masterplan for my 🐘 transition:
(1) I turn off all notifications NOW. Their draw is strong!
(2) I turn off tweet/toot syncing in January ‘23 and post links to my toots to reach you all for key announcements.
(3) I much hope to see the still missing ones there soon. ❤️

So excited to finally be able to share that @LeicaMicro and @ASIImaging have partnered to produce an amazing 'Single Objective Light Sheet' platform for gentle, high-speed 3D microscopy. Hoping it will bring the power of SCAPE and OPM to labs worldwide🔬https://www.leica-microsystems.com/company/news/news-details/leica-microsystems-and-asi-announce-partnership/ https://twitter.com/jsdaniel02/status/1599498412461674496

Check out our work on rapid automated organelle segmentation in volume EM, great to see this published in @JCellBiol@twitter.com. And on top of that we have released all code, models and datasets 🎉https://github.com/kirchhausenlab/incasem https://twitter.com/KirchhausenLab/status/1599792365601845248

New #cryoET structure from LSI Exeter colleagues Matthew Gaines et al. Bertram Daum lab, this time of the enigmatic #archaeal filament called 'thread'.
What I find cool about this work is that first they had the structure, then found the sequence based on glycosylation sites and bulky residues.
This #protein was also so ultra-stable, that resisted trypsinisation, so mass spec was not an option to identify it.

#introduction
I'm a theoretical neuroscientist in Paris.
These days I'm working on biophysics of action potentials (particularly the initial segment) and on integrative modeling of Paramecium, the “swimming neuron” (this is a unicellular protist that changes swimming direction with action potentials).
I also spend some time thinking about the relations between theoretical biology and theoretical neuroscience, ideas about life and ideas about brains.

3,013 neurons, half a million synapses: the complete #connectome of the whole #Drosophila larval brain!
Winding, Pedigo et al. 2022. "The connectome of an insect brain" https://www.biorxiv.org/content/10.1101/2022.11.28.516756v1
We’ve mapped and analysed its circuit architecture, from sensory neurons to brain output neurons, as reconstructed from volume electron microscopy, and here is what we found. 1/

New postdoc position to join my group at the Sars Centre, in #SunnyBergen https://www.jobbnorge.no/en/available-jobs/job/236193/postdoctoral-research-fellow-position-developmental-systems-in-a-simple-marine-chordate
Our review with Stefan Gründer and Audrey Ortega Ramírez is out:
"Neuropeptides and DEG/ENaC ion channels: a relationship from mammals to cnidarians"
where we conclude based on structural comparisons and the #phylogeny of #neuropeptide systems that the interaction of DEG/ENaC channels with neuropeptides has diverse structural bases and many origins.

Hi, we're now on Fediscience! #Introduction
We're an #OpenAccess not-for-profit journal that publishes and reviews #research in the life and biomedical sciences.
We want to improve the way research is practised and shared in part by working with early-career researchers #ECR and supporting #OpenSource technology.
We also just announced our new publishing model that we hope will tackle an overreliance on journal titles and publishing decisions as quality measures for science and scientists.

Dear fellow Mastodoners, To help the #TwitterMigration I only post teazers on twitter with a link to the mastodon content and a short message:
"Join us on the other side. Open, distributed, community driven, no ads, no AI feeding you, no random retweets, full control."
you could do the same
Finally, here is the Editor's evaluation from @elife
This paper reports on the development of an impressive microfluidic platform for the study of motility, and motility transitions, exhibited by single algal cells in circular confinement. Building on previous work that showed a three-state motility repertoire for certain green algae, the present work uses extremely long time series and a variety of physical perturbations to show how those dynamics can be altered by environmental conditions. The work will be of interest to a wide range of scientists studying motility and non-equilibrium dynamics.
