• Hydrogen-sulfide-induced human hibernation was proposed as a DIY suspended-animation technique; participants noted that human trials are stalled mainly by “ethical” objections rather than technical barriers, leaving the method untested but theoretically accessible.

• A new Science paper describes a reusable germanium-on-silicon CVD process that grows continuous, defect-free monolayer graphene that peels off intact, potentially slashing large-area graphene costs, while companion perforated-graphene membranes achieve “infinite-efficiency” water and chemical filtration for desalination and molecular separation.

• FDA cybersecurity guidance was dissected: post-market security patches for networked medical devices (infusion pumps, ventilators) do not require new FDA certification, yet hundreds of models still ship with hard-coded or absent passwords; insulin-pump users were urged to dump firmware and monitor updates themselves.

• The group explored open-source technology trees for post-collapse scenarios, critiquing “The Knowledge: How to Rebuild Civilization” for remaining book-bound instead of releasing machine-readable dependency data, and analyzed Thomas Thwaites’ “Toaster Project” as evidence that industrial artifacts hide enormous material and process complexity.

• Low-cost selective laser sintering (SLS) was discussed: Andreas Bastian’s open-source steel-sintering machine built for <$15 k (github.com/andreasbastian/opensls) and Anderson Ta’s DLP-based photolithography for 3-D printing living tissues were highlighted, along with Steve Kelly’s inkshield-modified RepRap for multi-color bacterial colony printing on agar gels.

• A 2007 paper on LCD-based maskless microlithography (http://diyhpl.us/~bryan/papers2/…) was shared, showing that ordinary laptop or LCD panels can serve as light sources for micro-scale photolithography, enabling garage-scale semiconductor prototyping.

• Debate over exercise substitutes included electrical muscle stimulation, myostatin inhibition, and biochemical shortcuts; participants questioned whether such methods could replicate the systemic benefits of traditional exercise such as anxiety reduction and inflammation control.
