- A talk was highlighted that offers the first non-hand-waving explanation for why the onset time of cannabis edibles varies between individuals while inhaled doses do not; the proposed mechanism involves differential “fat partitioning” rather than simple metabolism differences.  
- A novel physical-security concept was proposed: layering sound-conductive and sound-insulating materials so that their acoustic transfer function implements one round of SHA-256 via an S-box; stacking 64 such layers would yield an analog, cryptographically-secure audio scrambler that renders laser-microphone eavesdropping useless.  
- The same acoustic-hash idea was extended to transparent barriers (e.g., plexiglass) so that any reflected laser signal would contain only cryptographically mixed noise, effectively cloaking conversations without blocking sound transmission.  
- A link to the paper “Quantum Gravity Computers: On the Theory of Computation with Indefinite Causal Structure” (Springer, 2009) was shared via Sci-Hub, inviting discussion on computation models that exploit indefinite causal order predicted by quantum gravity scenarios.  
- A request for advice on choosing color schemes for scientific plots was posted, accompanied by a sample figure (http://itfromb.it/temp/fig.png) showing the need for colors in panel (a) that harmonize with the fixed palette in panel (b) without resorting to grayscale.
