- A new Cell paper (DOI: 10.1016/j.cell.2021.03.010) reported the discovery of a gene regulatory mechanism that explains why the human brain evolved to be disproportionately large compared with other primates; the Guardian summary and the full PDF were circulated.  
- Discussion referenced the Visual6502 project (visual6502.org), a browser-based simulator that animates transistor-level masks of classic microprocessors step-by-step in JavaScript, useful for understanding low-level hardware design and reverse engineering.  
- A YouTube channel showcasing DIY infrastructure was highlighted, including a homemade bandsaw mill built from old car wheels and an accompanying farm railway system that moves logs instead of the saw, illustrating low-cost, open-source fabrication techniques.
