- A debate over FDA regulation of early-stage COVID-19 vaccines: participants argued that informed, consenting volunteers should have been allowed to test candidate vaccines in February 2020 instead of waiting for full clinical-trial approval, citing the article “We Had the Vaccine From the Start—You Just Weren’t Allowed to Take It” (fee.org) and contrasting it with the agency’s willingness to accept thousands of “natural” deaths.  
- The conversation extended the regulatory-risk theme to SpaceX-style Mars missions, using one-way trips as a rhetorical device to question why society permits extreme personal risk in space exploration but not in experimental medicine.  
- Chris Phoenix, a noted nanotechnology ethicist, re-appeared in the community; his 2003 essay “Ethical Issues in Nanotechnology” (nanotech-now.com) was linked as background.  
- Practical biohacking notes: a member reported success with homemade conductive gel for ECG electrodes and asked whether thickening it with additional polyacrylate or switching to a roll-on applicator would improve usability.  
- Metformin sourcing without a prescription in the U.S. was raised as a low-cost longevity intervention worth investigating.
