Huge congratulations to all three Nobel Laureates, and especially Peter Hegemann! 👏 His seminal work on the green alga Chlamydomonas 🦠 laid the foundation for optogenetics. Thank you for putting Chlamy in the spotlight! ✨ Proof that groundbreaking discoveries don't always come from animal models! 🔬

How are mRNAs linked to molecular motors in mammalian cells? In our new preprint, we show that FXR1/2 are RNA adaptors for the microtubule motor dynein. Our findings have also prompted us to rethink how activating adaptors contribute to motor-based transport (1/n)

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.

Every electron counts⚛️! Researchers have determined the structure of the protein rubredoxin at an unprecedented 0.43 Ångström resolution. The method could now allow routine quantum crystallography of biological macromolecules. 👇More about this major advancement: www.mpinat.mpg.de/5314392/rn_2...
The image shows a valence electron deformation map of archaeal rubredoxin at 0.43 Ångström resolution: Refinement of the archaeal rubredoxin structure with the DiSCaMB transferable aspherical atom model (TAAM) library connected to BUSTER directly reveals quantum mechanical phenomena. The rubredoxin protein model (sticks) is surrounded by the electron density map (blue to red: low to high density). This valence electron deformation map derived from model refinement reveals electrons in the midpoint of chemical bonds and (valence) electron lone pairs.
