Does BioRxix not already allow you/us to do exactly that? Indexed repository, version-controlled updates, transparent options for peer feedback and author replies. Each version can have updated author contributions to document individual contributions.

How can one be scooped if one is the first to publish a preprint of a new discovery? πŸ€”

It is sad that we appear to consider the date of a journal stamp a more important sign of priority than the actual date of reporting your discovery to the scientific community.

Molecular basis for cellular compartmentalization by an ancient membrane fission mechanism The emergence of cell compartmentalization depends on membrane fission to create the endomembrane compartments. In eukaryotes, membrane fission is commonly executed by ESCRT-III, a protein complex con...

New preprint from the lab!!πŸŽ‰
We show that Asgard archaea ESCRT-III proteins can trigger membrane fission and reveal its molecular mechanism, offering clues to how these cells may have built internal compartments. But do these organisms even have these compartments?

CCP-EM Spring Symposia have become key venues for methods-focused cryo-EM advances and an annual fixture for structural biologists worldwide. Their early adoption of online talks set the bar for inclusive meetings, and even as they have grown over the years, they have kept a family feel. Kudos!

Not sure if this is what you are looking for, but in zenodo you can specify parent repositories as β€œrelated works” including the DOI to the original repository. This way you could link a subset of data (a particle stack in your case) back to its original source (the EMPIAR deposition).

We finally wrote up the paper for LocScale-2.0.

Please try it out. LocScale is evolving & we are actively building in new features and improvements. Your feedback will help us shape the next steps.

Together with colleagues at the Dept. of Microsystems Engineering, we are looking for a PhD student to develop methods for femtoliter-scale sample dispensing in cryoEM sample preparation.

Beautiful structures and mechanistic insight into endosomal lipid transfer!

Also a good example showcasing how contextualised map optimisation may be helpful in visualisation/interpretation of complex biological assemblies.

spent some time this evening updating the teamtomo.org site - if you're interested in cryo-EM + Python you might want to take a look around!

Want to try LocScale-2.0 without installing locally?

Check out ColabScale: just upload your maps or enter your favourite EMDB ID and run LocScale-2.0 in the cloud.

This is work led by @alok-bharadwaj.bsky.social with contributions by Reinier de Bruin and Lotte Verbeek.

Preprint(s) with detailed description underway. In the menatime we are happy for any feedback.

LocScale-2.0 is deliberately designed to optimise contrast for both high-resolution detail & weak contextual densities such as membrane/micelle or flexible/low-occupancy regions

LocScale-SURFER is a ChimeraX plugin aiding w/ visualisation of contextual structure.

We are happy to release LocScale2.0: a tool for context-aware, confidence-weighted cryoEM map optimisation.

Taking two half maps as input, LcoScale-2.0 produces feature-enhanced maps along with a robust confidence score that guides objective map interpretation.
