- Discussion of the evolutionary-biology roots of mate choice referenced Richard Dawkins’ “The Selfish Gene,” debated historical life expectancy, and explored whether beauty is a reliable proxy for heritable fitness.  
- A hardware-focused resource list was circulated:  
  – openknowhow.org as a searchable index of open-source hardware projects  
  – yeggi.com as a search engine for 3-D printable models  
  – OpenFlexure Microscope v7.0.0-beta1 documentation praised for its quality.  
- A TechRadar article on “self-destruct chips” that use electromigration both to create physically unclonable functions (PUFs) and to render used ICs unusable was critiqued; participants questioned whether the scheme truly combats counterfeiting or simply destroys legitimate second-hand parts.
