- FDA issued a public warning against “young donor plasma” infusions marketed as anti-aging or disease cures, prompting debate on whether banning the procedure domestically simply drives U.S. citizens to seek the same unproven treatment abroad.  
- A randomized, controlled-feeding human trial (N = 217, 6 months) reported that a high-fat diet—24 % of energy from n-6 PUFA via soybean oil—shifted the gut microbiome toward pro-inflammatory states, fueling keto-diet discussions about fat quality and omega-6 hazards.  
- Participants shared links on self-experimentation ethics, including the Hanley-Church paper “Self-Experimentation and Its Role in Medical Research” and a PNAS article framing access to scientific advances as a human right under the 1948 Universal Declaration.  
- New technical resources circulated: the Rebooting Web-of-Trust RWOT8-Barcelona proceedings on decentralized identity, MIT’s “Engineering a Safer World” systems-safety text, and a biorxiv preprint on super-resolution ion-beam imaging for subcellular drug distribution mapping.  
- Conversation turned to hardware hacks for neural interfaces: charlieplexing was proposed as a way to multiply effective I/O channels (n²–n per n pins) on implantable chips when reduced data rates are acceptable.
