• A brief Springer paywall bug exposed ~110,000 books and journals; participants rapidly scraped engineering and molecular-biology texts, and an informal “science liberation front” claims to have preserved a large fraction before access was cut off.  

• The Netherlands negotiated a national open-access deal with Elsevier requiring 30 % OA articles by 2018 and full OA by 2024, hailed in-channel as a landmark victory for open science.  

• An open-source DNA oligo-synthesizer project is underway, targeting femtoliter-scale droplets via repurposed Canon/Epson inkjet heads; technical hurdles center on patented 30–200 V piezo drive waveforms and high-voltage ASICs rather than chemistry.  

• Participants sketched a 75-year path to a Dyson sphere: starting with 1 m² solar collectors at 0.3 AU and doubling area annually yields the required 2^75 m²; near-Earth C-type asteroids were proposed as first feedstock for tele-operated self-replicating macro-machines.  

• A debate on molecular nanotechnology vs. macroscale manufacturing concluded that macro factories already have extensive literature and tooling, whereas mechanosynthesis still lacks a clear step-by-step route from an initial AFM tip toolkit to a programmable hydrocarbon assembler.  

• DIY brain-stimulation options were compared: transcranial magnetic stimulation demands lethal high-voltage engineering, whereas low-megahertz focused ultrasound reaches deeper brain regions with simpler electronics; Ben Krasnow’s TMS build and an ultrasound paper archive were shared.  

• Channel members distanced themselves from the “grinder” body-mod scene, emphasizing engineering rigor over aesthetics, and rejected the label “DIY H+ organization,” describing #hplusroadmap as an informal, project-oriented network.  

• Historical transhumanist knowledge is being consolidated: Deku-shrub is importing the defunct transhumani.com wiki into hpluspedia.org, salvaging QuteMol mechanosynthesis renders, bibliographies, and early H+ iconography while tightening editorial standards.
