- Cryonics research gap: Participants argued that a convincing small-mammal cryopreservation-and-revival demo would cost far less than commonly assumed, yet no systematic follow-up to Mike Darwin’s 1980s canine perfusion work (Alcor report: http://www.alcor.org/Library/html/tbwcanine.html) or the 1960s Suda cat-brain EEG study has been attempted, leaving the empirical base decades out of date.

- AGI vs. whole-brain emulation debate: A central thread contrasted “theory-first” AGI with whole-brain emulation (WBE), concluding that non-uploading WBE is effectively AGI because it bypasses the need to understand intelligence mechanisms; OpenCog’s 2017 “AGI scientist” roadmap was dismissed as over-optimistic and theory-laden.

- Falling cost of open-source bio-hardware: Chris_99 circulated a $33 microfluidic mixer slide catalog (https://www.anfractuosity.com/files/microfluidics/Product%20code_USD.pdf) and noted Chinese vendors offering similar chips for £21, illustrating rapid price drops in DIY microfluidics.

- Routing non-intersecting 90-degree paths: A technical sub-thread framed the problem of connecting fixed start/end points in 3-D space (e.g., microfluidic channels, PCB traces) with piece-wise differentiable curves or sine-wave sums that never share the same coordinate, debating PDE, graph-theoretic, and autorouter approaches.

- Gates Foundation open-access mandate: The channel highlighted the Foundation’s new requirement for immediate open-access publication of all funded research (~1,400 papers/year, $900 M budget) as a major accelerator away from paywalled journals.

- WuXi AppTec/BTNB “EXPLORER” library: Word spread that the 1.4-million-compound high-throughput screening library is now shipping to early-access U.S. clients, with Assay Depot providing free concierge services for BTNB tenants.

- NASA tensor-analysis primer: A free PDF of “Foundations of Tensor Analysis for Students of Physics and Engineering With an Introduction to the Theory of Relativity” (NTRS ID 20050175884) was circulated as a self-contained learning resource.

- Tooling frustrations: Participants vented about the Python Shapely library’s GIS-centric documentation and discussed the unreliability of paperbot/libgen for retrieving historical Journal of Applied Physics papers (doi:10.1063/1.1698511, 10.1063/1.1707491), prompting talk of a simpler URL-sniffing replacement.
