There's a presentation about (Re?)Building Textile Archaeology in the Nile Valley, hosted by the CTR, on December 9 - it's the inaugural lecture of Elsa Yvanez. You can join in with a pre-registration; more information about the lecture and how to attend can be found on the CTR website.
The Conversation has an article about the DNA of medieval Jews - apparently some mutations of the Ashkenazi subgroup can already be seen in gene samples from the 14th century.
An interesting site if you're looking at images with Christian content (and there's so, so many of them if you're looking at medieval art): christianiconography.info is a "Guide to Christian Iconography: Images, Symbols, and Texts".
