- A new antidepressant hypothesis claims that **all effective antidepressants (SSRIs, psychedelics, etc.) ultimately converge on the same pathway: BDNF release via the TrkB/mTOR interaction**, potentially explaining efficacy and guiding next-gen, lower-side-effect compounds; the claim is detailed in a 2024 Trends in Biochemical Sciences paper (https://www.cell.com/trends/biochemical-sciences/fulltext/S0968-0004(24)00037-9).

- The open-source **CollapseOS** project (http://collapseos.org/)—a Forth-based operating system designed to keep 8-bit microcontrollers usable after industrial collapse—was discussed; participants praised its practical “doomer” mindset while noting it is largely a solo effort.

- Users reported anecdotal **IBS, Crohn’s and other GI improvements in people taking the GLP-1 agonist semaglutide (Ozempic)**, prompting speculation that an unidentified dietary component may act as a “GLP-1 supercharger”; the EMA manufacturing report and a Science blog on counterfeit semaglutide were shared.

- DIY microbiome engineering ideas surfaced:  
  – **Engineering or evolving gut bacteria to secrete GLP-1 agonists or nootropics** as a continuous, low-dose delivery system.  
  – **Selective pressure devices** (antibiotic-releasing or heat-sterilizing marble-sized capsules) to shape microbial populations in situ.  
  – **Home culture protocols** for Akkermansia muciniphila using brain-heart infusion medium and a 1:1:2:1 chitosan/L-rhamnose/sialic acid/galactose mix.

- A commercial **GLP-1 probiotic** (Pendulum Life) already exists; participants debated DIY amplification (streaking pill contents onto agar, sterile broth expansion) versus the risks of perturbing the gut ecosystem, with warnings that uncontrolled introduction of invasive species or antibiotic use can trigger unpredictable ecological shifts.
