• A DARPA-funded “exosense” project streams Google Maps heading data to an Android phone that drives a belt of solenoids, giving the wearer a new, screen-free tactile sense of direction.  
• TRNP1 (Tudor-domain protein 1) was identified as a master regulator of mammalian cortical size: lowering its expression in mice increases basal-radial-glia and intermediate progenitors, causing an otherwise smooth cortex to form gyri and sulci, while over-expression expands surface area without folding.  
• Key papers shared include “Trnp1 Regulates Expansion and Folding of the Mammalian Cerebral Cortex” (Cell, 2013), “Control of cerebral size and thickness” (Springer, 2014), and “Cortical Gyrification Induced by Fibroblast Growth Factor 2” (J. Neurosci., 2013).  
• Participants debated whether Falcon-Heavy-class launchers could today deliver the seed infrastructure for fully-automated, self-replicating lunar or NEO resource extraction, concluding that only non-replicating, high-precision machines could currently be fielded.  
• Practical biohacking questions were raised about ordering phosphorodiamidate morpholino oligos from IDT for Duchenne exon-skipping and about developmental-stage molecules (FGF2, cyclin D4, VEGF, racetams) that might enhance fetal brain growth.  
• ROCK inhibitors such as fasudil and dimethylfasudil were discussed: they reduce outer-radial-glia translocation in human fetal cortical slices and, when given peripherally to mice, improve learning and working memory, suggesting a cognitive-enhancement pathway.  
• The group noted the absence of standardized, computer-parseable neuroanatomical data formats and the ethical hurdles of obtaining human fetal tissue, proposing ferret or improved mouse models as alternatives for studying cortical folding.
