- NIH BRAIN 2.0 initiative has selected an electron-microscopy-based, synaptic-resolution reconstruction of the entire mouse brain as one of its flagship “transformative projects,” signaling a major push toward whole-brain connectomics at nanoscale resolution.  
- A new pre-print on biorxiv, “Cellular and molecular probing of intact transparent human organs,” describes methods for rendering whole human organs optically transparent while preserving molecular detail, potentially accelerating 3-D histology and organ-scale systems biology.  
- Black Hat USA 2019 briefing “Everybody Be Cool, This Is a Robbery” (talk #16233) was flagged as relevant reading for security-minded biohackers, likely covering hardware or cryptocurrency attack vectors pertinent to DIY biomedical devices.  
- The diyhpluswiki repository received updated transcripts of the Lightning Network security panel, expanding open documentation on cryptographic payment-channel security practices that could be adapted for decentralized health-data marketplaces.  
- No extended technical debate was captured in this log slice; the substantive content consists primarily of link-drops and announcements rather than in-channel discussion or experimentation reports.
