- A Kickstarter campaign for “Holovect,” a volumetric laser display that draws 3-D vectors in mid-air by heating air to create visible plasma voxels, was discussed; participants questioned its physics (albedo vs. venturi/thermal effects), noted it is the second attempt after an earlier failed campaign, and debated whether the promised “open source” merely means an API/SDK rather than full hardware openness.

- Skepticism was voiced toward a recent paper claiming “synapses are not the locus of memory”; the counter-argument was that epigenetic and RNA-based mechanisms should be integrated with, not used to dismiss, synaptic models of memory storage.

- Robert Freitas’ respirocyte concept resurfaced: hypothetical 1-µm diamondoid artificial red blood cells able to carry 236× more oxygen than natural erythrocytes, potentially letting a human sprint at top speed for ~15 minutes without breathing—CO₂ clearance jokingly suggested as “farting.”

- A new Nature Communications paper (DOI: 10.1038/ncomms13304) on in-vivo correction of β-thalassemia in mice via γPNA gene editing delivered by nanoparticles was shared as a promising CRISPR-free gene-therapy approach.

- ImplicitCAD released a new version boasting 8× lower memory use, 3 % less CPU, and improved geometric precision; nmz787_i offered a GitHub test suite to validate STL export quality at varying resolutions.

- MIT’s “Project Manus” makerspace initiative was critiqued for its “Maker Bucks” micro-currency and restricted student-only access, with participants lamenting how university “maker culture” often excludes the wider community.
