Had a UKRI funded grant proposal rejected at the "AI triage stage". "This AI-based triage was used only to identify approximately 50% of the strongest proposals to take forward to full human review." 🧪 #academicsky
I am writing to let you know that, unfortunately, your application was not successful.

Review process

As part of the initial triage of the 179 proposals submitted to this call, each was assessed using an AI-based review. Every proposal was read independently by several different AI models against the same seven criteria used to shape this call (including cyber security relevance, research quality and novelty, importance of the problem addressed, feasibility of the project plan, likely outputs and impact, value for money, and responsible research practice), with each model asked to give a score and a written justification with supporting quotations from the text. To guard against any one model's idiosyncrasies, we also ran a second, independent process in which different AI models debated the merits and weaknesses of each proposal before reaching a judgement, again against the same criteria. Scores from both processes were combined to produce an overall ranking. 

This AI-based triage was used only to identify approximately 50% of the strongest proposals to take forward to full human review.  Projects selected for funding were drawn from those that progressed to the full human review stage. We recognise that AI-assisted assessment is a new and evolving part of the review process, and we are continuing to evaluate how well it aligns with the judgements of human reviewers on this call. We will soon produce a document detailing our method, so that others can build upon it and improve it.

Feedback on your application

Your application was not selected to progress beyond the AI triage stage.  To provide transparency on the outcome of this assessment, we are sharing below the scores (out of 5) from each of the two AI review processes described above, together with the mean score across the two processes.

In 2023, @nature.com published 'Papers and patents are becoming less disruptive over time', receiving world-wide media attention. Our Matters Arising, published after a 32 month delay (more on that soon), shows that the reported decline can largely be attributed to dataset artefacts. 🧵
The average CD_5 index per year for Web of Science. The original Park et al. decline (top curve) becomes essentially flat (bottom curve) when removing papers with CD_5=1. Those papers largely correspond to dataset artefacts.

Remember the spectacular claims from three years ago, that science is supposedly becoming less disruptive? Seems this was at least in part due to data artifacts. To be fair, the authors of the original study push back, that the new study is flawed as well. www.nature.com/articles/s41...

The protocol requires nothing more than standard sterile technique, no specialist kit, no perfect timing. Great for rescuing contaminated cultures and for bringing field-collected isolates into clean lab culture.

Once there are gemmae, move them onto medium supplemented with Plant Preservative Mixture (PPM), a broad-spectrum biocide and, voila, an axenic culture.

Darius Kosmützky @dariuskos.bsky.social · 31/07/2026
Our approach is more hands-off. Grow contaminated thallus under non-sterile, nutrient-poor conditions until it makes gemmae. The fungus usually does not grow on sand, thereby allowing separation. The only disadvantage is the time that plants need to grow: the whole protocol takes between 7-10 weeks.

Darius Kosmützky @dariuskos.bsky.social · 31/07/2026
The usual fix is bleach-sterilising gemmae. It works, but it's fiddly: labour-intensive, dependent on having gemmae ready to go, and the gemmae are time-sensitive about staying viable, i.e. it's a pain.

Paying for #peer-review increases speed and quality: www.nature.com/articles/d41... Great to have data supporting what most academics already know. I hope other journals take this up. So far reviewing remains largely unpaid labor layered onto already undercompensated #academic work.

Why paying peer reviewers works, according to a journal’s editor-in-chief
A biology journal that paid peer reviewers found that the approach cut the time to a first editorial decision by 85% and maintained high-quality reviews.
