- Google AI released an interactive, automated 3-D reconstruction of the entire fly brain, viewable in NeuroGlancer, as reported on the Google AI Blog.  
- nmz787 reported back from the 2019 Microscopy & Microanalysis conference with a $65 k price tag for a backpack-sized SEM that includes X-ray chemical analysis.  
- andytoshi circulated two references on lunar self-replicating solar factories: a 1980 NASA study (pdf) and a 2016 Discover magazine article on lunar solar power plants.  
- docl floated a high-stakes blockchain idea—using a satellite at L5 as a single, low-latency block validator—then identified a critical flaw: the scheme incentivizes adversaries to sabotage competitors’ network links to gain mining advantage.  
- DIYhpluswiki commits added yashgaroth’s myostatin-inhibition proposal and Bryan Bishop’s transcript of Bob McElrath’s talk “On-chain Defense-in-Depth.”  
- transhumanist_ proposed a non-penetrating BCI that would place a phonon/thermal sensor film directly on the cortical surface (inside the skull but outside the pia mater) instead of using penetrating electrodes, citing a “quantum microphone” paper (Stanford, 2019) that senses phonons in superfluid helium; discussion revealed the sensor currently requires cryogenic cooling, making it impractical for implants.  
- poppingtonic compared the idea to OpenWater’s red-light optical imaging and raised the standard concern about signal attenuation when sensors are not inside the brain tissue.  
- Dr-G described an “ant-uplift” experiment involving multiple colonies, mineral radiation, starvation regimes, and tiny steel weapons, prompting tongue-in-cheek discussion about the definition of uplift.
