- Transcranial direct-current stimulation (tDCS) was discussed as a DIY cognitive-enhancement tool; genehacker linked the Wikipedia page and a clinical-trials.gov study on using tDCS to improve memory and attention in children with schizophrenia, noting reported 40–60 % baseline improvements in small-n studies.

- Participants debated practical tDCS electrode placement, referencing the 10–20 EEG coordinate system and the need for better 3-D brain-region labeling; kanzure mentioned an abandoned project to build a detailed brain-structure ontology viewer.

- The channel explored “silent speech” interfaces: genehacker pointed to throat microphones as a near-term Ghost-in-the-Shell-style communication method, while fenn cited implanted-electrode research enabling vowel synthesis via thought.

- A major thread covered open distribution of scientific literature: kanzure revealed he had mailed a 120 000-paper, 70 GB collection to Boston’s Fab Lab for DIYbio use; ppk and kanzure brainstormed private torrent trackers, automated batch seeding, and image-segmentation scripts to extract figures from PDFs.

- kanzure shared several manufacturing-assembly research papers, including “Port-Compatibility and Connectability Based Assembly Design” and “Feature-Based Design for Assembly,” critiquing current ontologies for lacking functional-force data and arguing that geometry-only models are insufficient.

- genehacker highlighted UT Austin’s Solid Freeform Fabrication program, linking to work on flash-imprint lithography for nanostructures in hydrogels and membrane-less filtration research.

- Autodesk Labs’ browser-based 2-D drawing tool (Project Draw) and a JavaScript OCR Greasemonkey script for solving captchas were noted as examples of web-based rapid-prototyping and automation hacks.

- The group briefly examined Costa Rica “stem-cell tourism” videos showing wrist injections for autism treatment, using them as a case study in unregulated medical experimentation.

- kanzure posted Tim Hunkin’s “Secret Life of Machines” series, noting the author’s explicit encouragement of torrent distribution—framed as an example of open-access media aligned with transhumanist information-sharing ideals.
