- A transcript of the 16 Dec 2019 SF Bitcoin Meetup on BIP-Taproot and BIP-Tapscript was posted and subsequently typo-corrected on the diyhpluswiki (http://diyhpl.us/diyhpluswiki/transcripts/sf-bitcoin-meetup/2019-12-16-bip-taproot-bip-tapscript/).  
- Justin Moon’s “BitBoy” project—a stateless, QR-air-gapped DIY Bitcoin hardware wallet—was highlighted via Twitter video.  
- “Full noncontact laser ultrasound” was reported in Nature Photonics, demonstrating the first human in-vivo volumetric imaging at ~5 cm depth and meter-scale standoff with eye- and skin-safe optical exposure.  
- Multiple human-intelligence genomics papers were shared, including a GWAS for extremely high intelligence (Nature 2017) and a catalog of 31,389 fixed human-specific single-nucleotide changes versus archaic hominins (Nature Scientific Reports 2019).  
- Experimental evidence was discussed showing that the human-accelerated enhancer HARE5 drives faster cortical progenitor proliferation and a 14 % increase in upper-layer excitatory neurons in transgenic mice, supporting models of human cortical evolution.  
- Links to cortical-development studies were provided, covering environmentally induced brain morphology changes, artificial selection on brain size in guppies, and cerebral organoids as models of human-specific brain evolution.  
- A review on “tissue regeneration enhancer elements” was circulated as a potential route to unlock endogenous healing mechanisms.  
- Washington Post coverage of a DOJ investigation into Sci-Hub’s founder—alleging possible Russian-intelligence ties—sparked debate over whether open-access repositories constitute “piracy” and broader frustration with U.S. federal and media institutions.
