• Two recent Nature papers (NSMB structural biology, doi:10.1038/nsmb.2820; Nature Methods imaging, doi:10.1038/nmeth.2934) were fetched via paperbot from LibGen, illustrating the channel’s routine use of shadow libraries to bypass paywalls.

• Participants debated whether open-source microscopy should begin with quick-and-dirty commodity parts (microscope, $3 steppers, 3-D-printed mounts) or insist on first-principles engineering to guarantee micron-scale precision, with nmz787 advocating an “accessible anywhere” prototype and kanzure arguing for rigorous specs before ordering parts.

• A hybrid microscope/lithography platform is being scoped: cast-iron or epoxy-granite frames, crossed-roller linear ways, Raspberry Pi or Casio high-speed cameras, and two competing optical paths—(1) beam-splitter inside a trinocular scope to inject a Blu-ray laser through the objective, or (2) side-mounted laser module—targeting <$1 k BOM but acknowledging precision components may exceed that.

• Microfluidic “lab-on-a-chip” capabilities were mapped: 10–100 µm channels for DNA handling, Protein-A bead antibody purification, on-chip cell culture, acoustophoretic sorting, and tangential-flow ultrafiltration aimed at replacing $500–$20 k lab hardware with printable or home-built equivalents.

• Tangential-flow filtration was highlighted as the biggest recent purification advance; adapting it to micro-scale devices could continuously bleed off secreted antibodies while keeping cells in chamber, eliminating high-pressure chromatography columns.

• DIY DNA synthesis and sequencing were framed as the gateway to “interesting biology”: once DNA can be written, cells can be programmed to make arbitrary proteins or antibodies, and the same photolithographic masks used for microfluidics (1–100 µm features) can be repurposed for low-resolution microelectronics, potentially letting crypto communities subsidize bio-fab infrastructure.

• A plan emerged to decouple Zotero’s 200+ web-scraping translators from the full Zotero/Gecko stack and run them under Node/browserify so paperbot and other headless tools can reuse them; a patched translation-server fork already exposes PDF URLs to paperbot.

• Python–Windows integration bug documented: when using popen with pythonw.exe, one must explicitly supply a stdin file descriptor and avoid writing to sys.__stderr__ to prevent silent crashes.

• Open-source microscopy references shared: GitHub repo for embedded Moxie processor (github.com/atgreen/moxiedev), YouTube demo of virtual AFM using LAMMPS/VMD, and step-by-step guides for mounting infinity-corrected objectives on camera bellows (hydracarina.org/910, krebsmicro.com).

• Interest expressed in “young blood” rejuvenation: delinquentme called for bioreactors that culture cells to produce fresh blood as a practical transhumanist intervention.
