- Four- and five-base anticodon tRNAs can decode expanded codons (e.g., CGGUA) and incorporate non-natural amino acids without shifting the reading frame, opening routes to larger genetic-code alphabets (papers: NAR 2006, 2001).  
- Display technologies for evolving peptides or nucleic acids were catalogued: phage, ribosome, cell, mRNA, RNA-peptide fusion, and SELEX, with discussion of lesser-known “peptide display” variants.  
- A low-cost open-source atomic-force microscope (Stromlinet-Nano, ~€3 k) was highlighted; it has been Arduino/Raspberry-Pi upgraded for faster scanning and is marketed as a LEGO Foundation partner.  
- RFID-based indoor localization was debated: a FellowAI robot carrying an antenna array was critiqued because passive RFID tags already serve as precise fiducial markers, making the robot potentially redundant.  
- Historical flashback to Halcyon Molecular (PayPal co-founder backed) recalled their 2009 promise of <$100, <10-minute whole-genome sequencing via electron-microscopy-based DNA reading and the company’s pivot toward brain scanning.  
- Cambrian Genomics’ audacious 2014 roadmap was quoted: become the world’s largest DNA manufacturer within five years and “replace all natural organisms on the planet with better synthetic ones” within ten.  
- A GitHub project, “CredibleConfessions” (David Vorick), was linked—likely a cryptographic or reputation system for verifiable statements, though details were not discussed.
