# Key Points from IRC Discussion

• Transcranial Direct Current Stimulation (tDCS) was discussed as a non-invasive brain stimulation technique, with participants sharing research showing it can improve attention span by 40-60% above baseline and potentially help with conditions like schizophrenia.

• Brain-computer interfaces were discussed, including both invasive implants and non-invasive technologies like throat microphones that could enable silent communication similar to that depicted in "Ghost in the Shell."

• Several papers on assembly design and manufacturing were shared, including one on "Port-Compatibility and Connectability Based Assembly Design" that discusses how to model connections between parts in CAD systems.

• Participants discussed methods for distributing a large collection (70+ GB) of scientific papers for DIYbio purposes, debating the merits of torrents versus platforms like Scribd for searchability and accessibility.

• Solid Freeform Fabrication (SFF) research was mentioned, with particular interest in nanolithography applications and a paper on "Flash Imprint Lithography Using a Mask Aligner" for printing nanostructures in photosensitive hydrogels.

• A controversial stem cell therapy treatment for autism in Costa Rica was briefly discussed, with participants sharing YouTube videos showing the procedure.
