- Lifespan.io reported that a group of biohackers has carried out the first documented human plasma-dilution experiment; the protocol disclosed in chat calls for replacing ≥50 % of a subject’s plasma in two 700 mL sessions, each followed by infusion of ~70 mL of 20 % albumin solution.  
- Channel members debated the scientific merit of the plasma-dilution claim, noting that the published article lacked procedural detail and that routine blood donation already achieves partial plasma exchange.  
- Discussion of low-cost, open-source PCR hardware included:  
  – OpenPCR (≈$500) was dismissed as overpriced;  
  – A “light-bulb PCR” design by Russel Durret that uses an incandescent bulb and fan for rapid thermal cycling;  
  – Arduino code (CyclerCan) for controlling a hair-dryer-based thermocycler;  
  – Idaho-style glass-capillary systems praised for minimal thermal mass and reduced condensation.  
- A homemade muesli formulation (GitHub: l29ah/muesli) was shared as a potential remineralization drink for teeth; participants considered substituting chlorides with phosphates and debated the bioavailability of added minerals versus those bound in phytate-rich grains.  
- Fluoride’s neuro- and metabolic toxicity was discussed, with links to Harvard meta-analyses showing ~7-point IQ reductions and associations with diabetes; participants criticized the absence of a “Controversy” section on Wikipedia’s “Fluoride deficiency” page.  
- Edward Bernays’ historical public-relations campaigns—particularly the 1929 “Torches of Freedom” effort to market cigarettes to women—were cited as early examples of engineered social behavior change.
