Having seen the news: www.bbc.co.uk/news/article... thought I'd share a cilia movie captured at UCL GOS ICH with Eriomina Shahaj & Vanesa Papastavrou using simple DIC on a Nikon Ti2 with DIC at 60x1.4. 500 fps here slowed down 20 times. Processed with Nikon's denoiseAI and an unsharp mask in Fiji.

It was good that Nature News did comment on the winner's unwillingness to show non-edited images. It is telling and was missed in the pieces from The Scientist and BBC News.

This stood out in the Nature news coverage. I don't think that we will ever get to see the underlying data.

The SynthID watermark is a smoking gun. It means Google or ChatGPT AI image generating software was used. There is no appropriate reason for these tools to be used in microscopy.

Simon Cleary @simoncleary.bsky.social · 01/10/2026
Rule: no AI-generated images. The winner confessed to AI-generating all details in lower half of image! SynthID watermark present, so an inappropriate Google/chatGPT AI generation tool was used. Movie also biologically implausible - we are told it is one cell but it is over 50 microns wide!

A bit worried that this statement from Nikon seems to be referring to the post-processing movie as the source video

Simon Cleary @simoncleary.bsky.social · 25/09/2026
There is a clear distinction between processing images to remove noise + spillover to better see real things (fine) and generating fake structures and time points (not fair!)

Unusual that the winner suggests that we ask how AI was used but does not provide answers... or the source data used to generate the movie.

#FluorescenceFriday: Given the recently grown interest in ciliary beating, here is a movie of beating cilia in a human airway model that I captured last week with lattice light-sheet microscopy. No AI „processing“, this is the raw data! Frame rate is ca. 170fps, displayed here at 25fps.

Update on the "AI-based triage" which is getting lots of (negative) attention
In recent days, there have also been several reports on social media of applicants seemingly being rejected after “AI-based triage”. The funding, while originating from UKRI, was devolved to the Crane network, which is funded by the Engineering and Physical Sciences Research Council to strengthen the UK’s cybersecurity research ecosystem.

UKRI confirmed it did not carry out the AI triage process. A spokesperson said: “UKRI policy does not allow the use of generative AI to conduct application assessment. We are following up with the Crane network to review this situation in detail and ensure compliance with our assessment conditions.”

I would prefer a lottery system to a potentially biased AI-triage. Would also have lower costs for the funder.

Sounds sensible as Nikon comms do not seem to understand. The winner's responses have made people even angrier, but I think it is important to remember that this is a young scientist who also doesn't seem to understand the upset, and pile-ons can be harmful. Wrote this on Linkedin:
Screenshot of Linkedin comment response to Ning Xu - "Ning - I want to add that the greyscale images in your preprint look excellent and you shouldn't feel discouraged from research by how other scientists have reacted to your submission to this contest. People are upset about use of AI to generate images here because doing this gives the false and potentially harmful impressions that airways look like this (images from this competition get used a lot in education and science communication) and that we can already image them like this (it is important to be open about limitations of current approaches so that research funders understand the need to continue to support research). "

@healthcare.nikon.com - @cilialab.bsky.social is right, and promoting AI-generated images in this way sends the message that people do not need to buy the nice microscopes that you sell

Even if it were ok to add AI-generated details in the lower half of the movie, what we are now told is a section of one ciliated cell is way too wide to be based on real images of one cell.

...and I think that's important. The bottom half of the image is now stated as being faked, or inappropriately extrapolated from phase contrast details. If some of the cilia or some time points are also not from real signal, the images should definitely not be in the competition

There is a difference between applying LUTs and making efforts to reduce shot noise to enable viewers to interpret the true positions of real photons, and inappropriately applying AI tools to produce fake structures
110
Simon Cleary @simoncleary.bsky.social · 23/09/2026
So, it seems the winner was open about AI use but the judges did not recognise that AI has been inappropriately applied in this instance. People editing comms knew that AI enhancement/generation would be controversial so they removed mention of it in the piece on the winner.

Simon Cleary @simoncleary.bsky.social · 23/09/2026
In the original version of this piece the person/people writing for the Nikon competition also removed a mention of AI by the winner:
Original paragraph reads:
'His advice to other researchers considering entering the competition is straightforward: “Take care of the sample, use as little light as possible when working with living cells, and most importantly, keep recording. The best moment usually appears right after you decide to stop.”'New paragraph has added section on AI: 'His advice to other researchers considering entering the competition is straightforward: “Take care of the sample, use as little light as possible when working with living cells, and embrace AI to reveal the hidden beauty in your data. Most importantly, keep recording. The best moment usually appears right after you decide to stop.”'

These tools are easy to use but produce hallucination artifacts when applied to images different from those in the training dataset. In the case of the winning sequence, these are totally fake, mis-scaled details resembling features of confocal images of stained membranes, nuclei, and mitochondria

You can see the nice (label-free) images that this microscope modality produces in this preprint: doi.org/10.48550/arX... Not sure how you would get from this to the prize-winning image (with very long anenome-like cilia) without genAI shenanigans...

Would love more info on the colours and modality. A moving plane of focus might explain the 'shifting' nuclei and appearance of cilia.

Nikon's tool 'Denoise.ai' can produce strange artifacts when applied to images of unstable (live tissue) preparations. They should probably add a big warning message on this.
