Today I am sharing a new preprint and accompanying blog post. Hundreds of published papers include impossible western blots showing protein expression in cell lines that have deleted or mutated genes. These clumsy mistakes are widespread and repeated by LLMs.

Glad my voice could contribute to this special issue of Molecular Cell on AI in molecular biology. I see a lot of promise though some perils do exist! Several other voices' opinions to read there: Ellen Zhong, Jianyi Yang, Quan Chen, Alan Wong and Judith Zaugg. www.cell.com/molecular-ce...

Molecular Cell@cp-molcell.bsky.social

Artificial intelligence is rapidly transforming molecular biology. In this issue of Molecular Cell, we highlight recent advances at the intersection of AI and molecular biology, spanning structure prediction, design, genome engineering, and functional genomics. www.cell.com/molecular-ce...

Very happy to see our work highlighted by @natcellbio.nature.com. A great team effort and a fascinating example of how a simple physical principle can connect mitosis across eukaryotes! @lgudlin.bsky.social, @krunovuk.bsky.social, @kopslab.bsky.social

☕ @lgudlin.bsky.social, @krunovuk.bsky.social, Novak et al propose spindle scaling in response to chromosome crowding consistent across eukaryotes; metaphase plate width scales with genome size following a power law with an exponent of ~1/3. @ivatolic.bsky.social www.nature.com/articles/s41...

Peter Hegemann and Georg Nagel – awarded the 2026 medicine prize – discovered a remarkable protein, channelrhodopsin, in a single-celled alga. Hegemann wondered how Chlamydomonas, a single-celled alga, is able to swim towards a light source.

I spoke with @nature.com about the Nikon Small World controversy. As AI becomes part of scientific imaging, we need greater transparency about what was measured, inferred or generated. It's not about excluding AI. It’s about preserving trust in scientific evidence. www.nature.com/articles/d41...

In the original version of this piece the person/people writing for the Nikon competition also removed a mention of AI by the winner:

Paul & Virginie - Centriole Lab reposted

This is the updated part. Looks like the movie is an AI-generated fluorescence image from a non-labeled acquisition technique. No indication that the Small World jury and organizers have requested and verified the raw data (as mentioned as a possibility in the competition rules)

Nikon's response to me on Linked in: "We’ve updated our detailed article with insights from the winner, which may answer some of your questions. We encourage you to check out the link to dive deeper into the technical details" 1/n www.nikonsmallworld.com/masters-of-m...

From the new info my bet is fluo labeling inference pushed to 11. Hallucinating nonsensical DAPI nuclei, mitochondria stain, membrane labeling from a kind of phase contrast image: wrong localization, wrong scale, wrong movement. Keeping this movie as SWiM winner is a disgrace to the competition

The might have also added a scale bar (not sure if that was there before?). This would make the blue structures very small.

Very proud of the team, led by @baukjeje.bsky.social & @fmikus.bsky.social To all of you doing #Expansion #Microscopy #UExM Try Concanavalin A. Its cheap, easy to use & labels the #nuclear #Envelope @moorefound.bsky.social @embl.org @sciencesunige.bsky.social @erc.europa.eu @snsf.ch

Baukje Hoogenberg@baukjeje.bsky.social

Do you want to label the nuclear envelope? Do you work on a non-model species? Try Concanavalin A! We tested ConA on various species across the eukaryotic tree and find it is a very useful ExM-compatible marker for the NE and ER. Read all about it in our preprint: www.biorxiv.org/content/10.6...

First day here and I brought a paper. Three years of cryo-FIB-ET on human airway cells, nine proteins identified and two new PCD genes at the end of it. Grateful to the teams in Munster (Omran Lab), Boston (@alanbrownhms.bsky.social, Hawkins Lab) and Geneva (@centriolelab.bsky.social).

Alan Brown@alanbrownhms.bsky.social

Millions of beating cilia keep airways clean. At the base of each is the transition zone (TZ), a gate that controls which proteins enter and leave. In our paper out today in Science, we used cryo-FIB-ET to image the TZ inside human airway cells www.science.org/doi/10.1126/...

Dear #CryoEM and #Microtubule enthusiasts, I’m thrilled to have been part of this exciting journey: www.biorxiv.org/content/10.6... We discovered and characterized a manchette-like microtubule machinery in Xenopus spermatids, likely involved in sperm reshaping and membrane reorganization. (1/3)
