- The UN is drafting a report on geoengineering, signaling growing institutional attention to large-scale climate interventions.  
- A DIY microlens-array fabrication method was proposed: dip a perforated mesh into clear acrylic resin so droplets cling to the holes and cure into lenses; curvature could be tuned by mesh retraction speed, spin coating, or electrowetting.  
- Participants refined the concept by suggesting resinphilic/resinphobic surface patterning, vibration-assisted separation, and etched-hole substrates for volume production.  
- The ImplicitCAD and hslice author (juri_) noted daily 3-D math work, while archels mentioned prior experience on a physics engine, highlighting the channel’s overlap of software and hardware expertise.  
- A brief critique was shared of sensationalist warnings about gene editing, citing fears of “designer babies” and “Spider-Man or Wolverine” traits as examples of unchecked speculation.
