- A paper on plasmon-enhanced enzymatic reactions was shared, showing that the distance between gold nanoparticles and enzymes, as well as nanoparticle loading density, can be tuned to boost catalytic activity—relevant for open-source bio-reactor or biosensor designs (PMC3177324).  
- Discussion referenced a Lancet article reporting measurable cognitive deficits in people who have recovered from COVID-19, highlighting long-term neuro-sequelae as a concern for biohackers tracking post-viral cognitive metrics.  
- The MetalicaRap open-source metal 3-D printing project was lamented as having fallen short of expectations, underscoring ongoing challenges in low-cost, open hardware for rapid prototyping of high-performance materials.  
- Elsevier paywalls briefly broke the channel bot’s URL-title fetcher, prompting a meta-commentary on the accessibility of scientific literature within DIY and transhumanist communities.
