- A Science Advances paper on “Anti-USAG-1 therapy for tooth regeneration through enhanced BMP signaling” was shared as a promising route to biological tooth regrowth.  
- Discussion of electrochemical DNA synthesis: a participant (xna) is preparing to meet with the remnants of Azco Biotech and requested reading material; kanzure supplied a curated archive at diyhpl.us/~bryan/papers2/DNA/ with subdirectories on phosphoramidite chemistry.  
- Practical barriers to open biotech collaboration were noted: Biolytic in the Bay Area is still enforcing BSL-2 lab visits with intercoms for COVID safety, complicating hardware demos.  
- A critique of “trainability” compared brute-force matrix-multiplication approaches (e.g., self-driving AI) with biological chemotaxis systems such as vine growth, hinting at the difficulty of engineering incremental, controllable in-vivo behaviors.  
- A satirical proposal for “open-source ransomware” that forcibly injects permissive licenses into proprietary code sparked debate on whether such actions would create legal “reasonable doubt” or simply entrench the existing copyright regime.
