By 2016 we had figured out how to take very high resolution microCT scans of things with ink on them and "unroll" them virtually. This was successfully used to read text from a scroll that had been turned into a column of charcoal in a fire. The ink is different enough from the parchment, even when both are partially combusted, to make the technique work.
Figure 1 is ... striking:

- habi 7y agoHey! Is 'we' you who has presented this at the Bruker User Meeting? I'm the guy who presented the zebrafish gills story this year :) Your work with virtually unscrolling the scrolls is amazing, keep on trucking! Have a good day!
- interactivecode 7y agoCome on, you can't mention zebrafish gills without actually telling the story!

- habi 7y agoExactly, nice search engine fu :) Here's a bit more information: https://news.ycombinator.com/item?id=21782922 https://news.ycombinator.com/item?id=21782922
- habi 7y agoSorry, didn't want to hijack the thread :) We were able to show that the gills of zebrafish grow and get more 'sparse' with endurance training. This means - to our understanding - that the water can more easily penetrate the gills and is transported through the gills more efficient, i.e. the oxygen is extracted from the water more efficiently. Here's a little bit of the backstory on my 'work' blog: https://micro.tomo.graphics/manuscripts/2019/08/26/adaptation-of-zebrafish-gills-to-endurance-training/ https://micro.tomo.graphics/manuscripts/2019/08/26/adaptatio... And here's the manuscript on bioRxiv: https://doi.org/10.1101/744300 https://doi.org/10.1101/744300 Just yesterday we submitted the 'minor revisions' for our submission of the manuscript to PLOS One :)
- blackstache 7y agoHey, that was me! What a pleasant surprise, you made my day. Have a good one yourself!
- dredmorbius 7y agoEven papyrus scrolls not already charred by historical events (e.g., at Pompeii and Herculaneum) were often considered incense and burned by their discoverers. One shudders....
- woliveirajr 7y agoI always wonder if all those reports are real, are inflated (to show some bad-looking-past and how noble we are today) or if was a form of hiding a kind of robbery (see, I found something, but wasn't possible to bring it to the museum/king/whatever because... my team just burned it).

- dredmorbius 7y agoin 1778, a Danish classical scholar named Niels Iversen Schow bought a papyrus scroll from a hoard alleged to have been discovered near the pyramids at Giza, whereupon the “native” sellers reportedly tore up and burned the rest so as to enjoy the pungent smoke. -- Keith Houston, The Book https://www.worldcat.org/title/book-a-cover-to-cover-exploration-of-the-most-powerful-object-of-our-time/oclc/958290032 https://www.worldcat.org/title/book-a-cover-to-cover-explora...

- saganus 7y agoThat's truly amazing. I can't even fathom how to handle that, let alone how to _read_ something out of it. Striking is an understatement.
