• A debate emerged over whether the NAD+ precursors NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are safe, with participants noting that NMN is claimed to address “many of the 10 root causes of aging” while openly questioning its potential carcinogenicity.

• A Frontiers in Aging Neuroscience paper (DOI 10.3389/fnagi.2022.813531) was shared that documents continuous EEG from an 87-year-old patient during cardiac arrest, revealing “enhanced interplay of neuronal coherence and coupling in the dying human brain.”

• A Tech Explorist article on 3-D-printed gyroid catalysts that supposedly turn concentrated hydrogen-peroxide into “non-toxic rocket fuel” was critiqued: participants argued the headline is misleading because high-test H₂O₂ remains caustic, and the gyroid geometry shown in the article is actually a honeycomb lattice.

• Discussion clarified that while hydrogen-peroxide monopropellant is less toxic and easier to handle than hydrazine, both remain hazardous; hydrazine’s primary danger is systemic toxicity and carcinogenesis, whereas peroxide causes immediate tissue destruction.

• Mathematical and practical properties of the gyroid minimal surface were dissected: it is “infinitely connected” in the topological sense, yet printable gyroid lattices are finite approximations used for lightweight, high-strength internal structures in FDM 3-D printing.
