We present multi-immersion Oblique Plane microscope (miOPM), a light-sheet platform that can be adapted to a wide range of applications, from sensitive live cell imaging to imaging organs and cleared tissues.

Traveling in #Germany. The open hostility of a Sachsen lady at the Bahnhof store towards an immigrant customer who just wanted to buy cigarettes. He was on a job. How are they suppose to belong?

Sex or growth? Life must continually balance these strategies. We forced yeast to choose and captured the trade-off in real time. Evolution rewired existing regulators and fixed them through genetic assimilation, creating specialists for sex at the cost of growth.

Thrilled to finally share this seven-year storyβ€”a journey that began during my postdoc in Sophie’s lab and continued for four more years as I built my own lab in Shenzhen.

Our latest preprint! Into morphogenesis, Yap, ECM, signaling, vertex models, feedbacks/robustness? There is something here for everyone. We discovered a positive feedback loop that extends inner ear canals, and a built-in mechanism that shuts it down when morphogenesis is done. tinyurl.com/464wsjhd

Do you mean to redirect it all to a centralized pre-print server, such as bioRxiv? Besides costing A LOT of money, this smells of a monopoly, which is never good.

In this intriguing paper published from the lab of @amartinezarias.bsky.social , they looked at the effects of size on morphology, tissue composition, and gene expression of gastruloid development. They found that AP elongation dynamics is size-dependent! Check it out here:

I cannot claim to understand the economics of it, but I think the hefty price tag on OA publication comes from having dedicated people perform these kinds of checks. (besides peer review and, well, profit). I don't see how bioRxiv can do anything near this and remain "free".

Dear JEDIs,
as we are self-organizing using the #EDRC as a nucleator we decided it is time for a JEDI database to boost our network! If you identify as a JEDI, please contact us here or send a mail to katja.rust@uni-marburg.de to be added to our database.

Back to work on #bigvolumebrowser, I've added the import of point clouds that change over time. The test data generation was a pleasant detour into the world of attractors (Thomas' cyclically symmetric is shown).

By videos, I mean supplementary videos that support the conclusions of the work. You CAN upload them to bioRxiv, but AFAIK you don't HAVE TO. For a worldwide pre-print mega-repository, even the storage capacity may become an issue.

Should be is not good enough. There will always be a perfectly defensible reason to post the main text without the supplements (which are not ready for prime time). It needs the editorial staff to let you know that we cannot proceed unless you include the file you are referring to in the main text.

I'm not sure I interpret you correctly, but if bioRxiv were to go down that road, i.e., requiring more and more precision at the pre-print submission stage, wouldn't the costs skyrocket?

If we are to read exclusively pre-prints in the future, can we at least require to inline Figures with text? The pre-print format is all geared towards peer review, not the convenient presentation of the science.

I can see that this potentially shifts the emphasis to pre-prints. But, with pre-print servers everything is voluntary. There is often no supplements, no videos, no source data, no one mandates deposition to repositories (or?). This is what journals do. Now all that will be behind the paywall.
