• A German high-school student received practical advice on launching a school biotech club, including talking points for teachers and direct contacts in the Berlin DIY-bio scene (Matthias Bock, Philippe S., Andreas).  
• kanzure released a manually-curated global directory of DIY-bio groups (http://diyhpl.us/wiki/diybio/groups/) to replace the outdated diybio.org/local map, while participants observed that the movement has fragmented into offline local spaces coordinated mainly by mailing lists.  
• nmz787 circulated a new preprint on imidazole-based small molecules that stimulate neurogenesis in pluripotent cells (http://diyhpl.us/~nmz787/pdf/Imidazole-Based_Small_Molecules_that_Promote_Neurogenesis_in_Pluripotent_Cells.pdf).  
• The channel evaluated CrossRef’s pdfextract tool (https://github.com/CrossRef/pdfextract) for automated metadata extraction from scientific PDFs, finding usable title data in only ~33 % of a local corpus.  
• A CAD/microfluidics workflow debate contrasted designing in meters and letting downstream solvers (COMSOL, Fluent) handle unit conversion versus exporting micron-scale geometry for simulation packages that require it.  
• Hardware sourcing notes: 80/20-style aluminum T-slot extrusion is available on eBay for ~$4/ft, with Makerslide suggested as an alternative rail system.  
• Paperbot’s Sci-Hub integration successfully retrieved one Annual Reviews paper but failed repeatedly on Wiley URLs, highlighting ongoing reliability issues with automated paywall bypass.  
• Participants warned that framing student projects as “DIYbio” can trigger institutional resistance; “school biotech club” is a more effective label, and most serious practitioners still recommend completing formal science degrees.  
• Autonomous-camera quadcopters AirDog and Hexo were discussed, with emphasis on short battery life and the need for automated battery-swap landing platforms.
