- A Nature paper on “Regulation of the one-carbon folate cycle as a shared metabolic signature of longevity” was shared (https://www.nature.com/articles/s41467-021-23856-9), highlighting folate metabolism as a potential lever for lifespan extension.  
- Kent Kemmish’s “Demonpore 64” open-source biology game-console project was discussed; collaborators report the electronics and software stack are complete end-to-end, but high-volume manufacturing is stalled by cash-flow and the global chip shortage.  
- nmz787 (now on a lithography CAD library team at Intel) described an experiment to laser-cut micropores in cigarette-pack-grade plastic film using a Q-switched “fast” laser as an ultra-cheap membrane prototyping method.  
- Participants debated practical workshop infrastructure: nmz787 sought advanced garage-door sealing solutions to exclude dust, insects, and mice for a new 10 ft × 2 door workshop extension, while L29Ah[XMPP] asked about hand-held power tools for digging a forest dugout unreachable by excavators (post-hole digger suggested).  
- Alex Wellerstein’s new book “Restricted Data: The History of Nuclear Secrecy” was promoted—signed copies available for the cost of shipping from a local bookstore (https://alexwellerstein.com/writing/books/restricted-data/).
