• Nuclear-isomer energy: 178m2Hf and naturally-occurring 180Ta are candidate isomers for stimulated gamma emission; the core controversy is whether the triggering mechanism works at all, with hafnium selected because theory predicts the lowest activation barrier.  
• Hand-grenade-scale “dial-a-yield” isomer bombs could deliver city-block to single-building destruction and might power rockets or drones, though critics note the military already expends $20 M cruise missiles on low-value targets.  
• F-35’s abundant onboard electrical power and prestige make it a magnet for fiber-laser and high-power-microwave add-ons, yet the platform’s staggering cost remains a central concern.  
• Phage therapy is re-emerging as a practical response to the first U.S. CRE “superbug” case, highlighting bacteriophages as a viable countermeasure against antibiotic-resistant infections.  
• C. elegans whole-brain emulation is viewed as a <5-year milestone because the 302-neuron connectome is fully mapped; debate centers on whether additional dynamics or ion-channel data are required for functional fidelity.  
• Reversible computing could, in principle, operate at 0 K with zero energy loss, raising the open question of whether total “thought count” diverges as available energy asymptotically approaches zero.  
• A cryopreservation charity is proposed to preserve fluent speakers of dying languages via brain-only vitrification or plastination, circumventing cultural objections to whole-body storage while safeguarding linguistic knowledge.  
• Cryonics is framed as an information-preservation technology: Alcor’s vitrification protocol is argued to preserve the full connectome, proteome, and epigenetic marks such as cytosine methylation, making future data extraction feasible even if biological revival is uncertain.
