Julienite is just blue. Halite (comes in different colours) is necessary to human life, used as art material: it’s carved, watercolour effects, salt prints, glazes, installations & more. As a marine geophysicist who does marine electromagnetic surveys depending on salinity: vote halite! #MinCup26
“Japanese Artist Motoi Yamamoto’s incredible, labyrinthine installations are the result of 45 hours of meticulously piled grains of salt, strewn inside a medieval castle in the South of France” via booooooom.com

The photo shows a stone chamber with vaulted ceiling in which Yamamoto has installed salt so it looks like tiny mountains and a large blood red floor surface covered with a salt labyrinth like a Turing pattern. A carved medieval scene in halite with a kneeling man and crowned woman and armoured knights in the background in Wieliczka, Poland’s salt mine via Wieliczka Salt Mine Tours “Spiral Jetty is a work of land art constructed in April 1970 that is considered to be the most important work by American sculptor Robert Smithson. Smithson documented the construction of the sculpture in a 32-minute color film also titled Spiral Jetty. Built on the northeastern shore of the Great Salt Lake near Rozel Point in Utah entirely of mud, salt crystals, and basalt rocks, Spiral Jetty forms a 1,500-foot-long (460 m), 15-foot-wide (4.6 m) counterclockwise coil jutting from the shore of the lake.” Via Wikipedia 

This aerial photo (Dia Art Foundation / Nancy Holt / Holt/Smithson Foundation) shows the burgundy reddish lake, the spiral earthwork whitish with salt and arid shoreline.19th century salt print (early photographic method) of a bearded man in jacket facing left. The area outside of a rectangle with his face is much more faded sepia toned. Below in pencil is written “Charles Louis Wallace”

“The materials required for salt printmaking, the oldest negative-to-positive photographic technique, are simple: silver nitrate, cotton or rag paper, water, sodium thiosulfate, sunlight, and table salt” via The Harvard Gazette

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.
