Screenshot of article summary of: Toward Science-Led Publishing by Damian Pattinson, George Currie published as an opinion piece, in Learned Publishing Summary The current dynamic of scholarly publishing prioritises the wants of the publishing industry over the needs of the research community. This article explores this theme through the lens of ‘publisher-led science’ as a description of our current status quo, and through ‘science-led publishing’ as an improved future state. We argue that financial motivations central to most publishing distort how research is presented, how it is assessed and even what research is undertaken, leading to a system that hinders, rather than facilitates, scientific progress. We propose three elements of a science-led publishing approach that would accelerate research communication, incentivise collaboration between authors, editors and reviewers, and create a more transparent and equitable research landscape. We believe that research funding and research assessment are two of the primary levers for wider change in research and research culture and consider the future purpose of scholarly publishing in a world where these proposals have been widely adopted.

Does publishing serve science or is science serving publishing?

Damian Pattinson and I (@elife.bsky.social) argue scientific publishing has evolved into a system that, rather than facilitate scholarly communication, distorts and dictates it.

Hey #TeamTomo,
Ever been in need of a tutorial about the fundamentals of cryo-electron tomography? From preprocessing raw frames to high-res subtomogram averaging?
That's why @florentwaltz.bsky.social and I made this website!

tomoguide.github.io

Follow the thread 1 /🧵
#CryoET #CryoEM 🔬🧪

You want to start tomography? Solve structures inside cells? Reach Nyquist 😳 ? @phaips.vd.st and I have a website for you! tomoguide.github.io
You'll find a tutorial on how to reconstruct tomograms, pick particles and do subtomogram averaging, using different software!
Hope it will be useful !

🦠🧠 MemBrain update! 🧠🦠
We’ve updated our preprint! It now covers the full MemBrain v2 pipeline for end-to-end membrane analysis in #CryoET: segmentation, particle picking, and spatial statistics.

Hey Everyone!❄️🔬 We have two fully funded PhD positions @humantechnopole.bsky.social this year!
Help us understand better how one of the main stress regulators - the nucleolus - integrates synaptic inputs!🧠Find all the calls - also from my amazing colleagues - here: www.semm.it/education/ho...

Great picture. Daliesque.

Asgard archaea are full of surprises, this time we found (tiny) microtubules (snapshots of microtubule evolution?!) - Check out our new paper on the cytoskeleton of Lokiarchaeum ossiferum: www.cell.com/cell/fulltex...

The final version of our work on the in-cell architecture of the mitochondrial respiratory chain is now online in @science.org 🎉
You can find the full story here www.science.org/doi/10.1126/...
@verenaresch.bsky.social did a wonderful job on the cover and animation, she really brought it to life 👩‍🎨

Check out @deglushk.bsky.social 's method to measure membrane thickness in cryo electron tomograms!

Big news: we are setting up a new non-profit organization to run bioRxiv and medRxiv. It's called openRxiv [no it's not a new preprint server; it's dedicated organization to oversee the servers] openrxiv.org 1/n

Three AI-powered steps to faster, smarter peer review Tired of spending countless hours on peer reviews? An AI-assisted workflow could help.

Let's talk about this Nature piece in more detail.

I've rarely read something so anti-scientific anywhere short of the National Review.

Happy to share our manuscript on the in situ visualization of the copia retrotransposon in its final form today published in @cellcellpress.bsky.social www.cell.com/cell/fulltex.... What’s new?

Rare cellular events observed in the cryo-ET dataset. Slices through tomograms (left) with corresponding 3D segmentation (middle and right). Right panels show enlarged views of the boxed regions in the middle panels. A) Mitochondrion at the plasma membrane, tethered to microtubules by thin filaments of unknown identity. Segmented classes: nuclear envelope (light blue), nuclear pore complex (dark blue), 80S ribosomes (orange), mitochondrial membranes (dark red), ATP synthase (royal blue), plasma membranes (grey), microtubules (pink), filaments (yellow), endoplasmic reticulum (purple). Zoomed-in panel shows thin filaments running between microtubules and the mitochondrion at the plasma membrane. Note that this tomogram contains two closely appressed cells, and thus, two plasma membranes with cell walls between. B) Mitochondrial fission event with ER membrane interactions. Segmented classes: mitochondrial membranes (dark red), ATP synthase (royal blue), 80S ribosomes (orange), thylakoid membranes (green), PSII (bright yellow), cell wall (grey), ER (purple), fission site containing filamentous structures perpendicular to the mitochondrial long axis (pale yellow). C) Ciliary transition zone between basal body and axoneme, including assembling IFT train and stellate structure77. Segmented classes: microtubule doublets (light blue), central microtubule pair (light green), stellate structure (pale red), IFT train (yellow). D) Pyrenoid tubule extending from the thylakoids into the phase-separated Rubisco matrix of the pyrenoid. Minitubules originate from thylakoid membranes82. Segmented classes: thylakoid membranes (dark green), PSII (yellow), pyrenoid tubule (lime green), Rubisco (lavender blue), minitubules (orange). Scale bars in A-D: 100 nm. Related to Fig. 2C-H.

To all #TeamTomo #CryoET and #Chlamydomonas aficionados: we have updated EMPIAR-11830 with a bug fix concerning some cryo-CARE denoised tomos as well as additional files and metadata! 🎉👩🏽‍💻

Extremely excited to be joining the vibrant community of the Vienna BioCenter to build up cryo-ET and cryo-FIB milling on campus soon!

Give control to shareholders, and enshittification will happen, where a relentless drive for growth will reduce quality for users. It would be cheaper and better to keep companies away from control over scientific publishing. Scientists do most of the work anyway. Look at @elife.bsky.social!
