"We don't die when the body starts to end. Because what we leave is a message, which is left and this will survive us." - Rita Levi-Montalcini, awarded the Nobel Prize 40 years ago for her discovery of growth factors. She was the longest-living laureate, passing away at the age of 103 years.

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.

Proud to share our new paper in EMBO Reports! 🧬 How does a cell "decide" to become lymphatic vs blood endothelium? Turns out it's not just which genes switch on — it's how the genome folds around them. 💥 link.springer.com/content/pdf/... #Lymphatics #Zebrafish #DevBio #VascularBiology #Genomics
The topologically associating domains (TADs) and chromatin accessibility of lymphatic endothelial cells diverge from those of blood endothelial cells. These differences underlie the activation of LEC-specific regulatory networks governing cell identity and involving genes linked to lymphatic disease.

Dr. Patricia Bath overcame sexism, racism & poverty and saved the sight of millions of people. She invented the Laserphaco Probe for cataract treatment, 1986; it was patented in 1988. She co-founded the American Institute for the Prevention of Blindness, 1976. She died #OTD in 2019. #WomenInSTEM
A vibrant color historical photograph capturing the brilliant ophthalmologist, inventor, and academic Dr. Patricia Era Bath (1942–2019) in an office or laboratory setting, radiating an aura of confident intelligence and warm approachability. Occupying the center and right of the shot, Dr. Bath sits facing forward, smiling brightly with a direct, engaging gaze at the camera. She is dressed in a professional white medical lab coat—subtly embroidered with "Dr. Bath" in red cursive on the left lapel—worn over a light blue button-down denim shirt and accented by a polished gold chain necklace. Pens are visible tucked into her left coat pocket. Positioned prominently to her right on the left side of the frame is a large, white medical laboratory microscope or ophthalmic imaging equipment with black eye-pieces. The background shows a white wooden bookshelf packed with colorful medical texts, binders, and stacked papers. This portrait carries immense historical significance, honoring a legendary trailblazer in STEM who became the first Black female doctor to patent a medical device—the revolutionary Laserphaco Probe for cataract treatment—fundamentally restoring sight to millions worldwide.
