- Neuro-evolution as an alternative deep-learning paradigm was highlighted via an O’Reilly article (https://www.oreilly.com/ideas/neuroevolution-a-different-kind-of-deep-learning).  
- nmz787 reported first successful ADC reads on the open-source “culture_shock” cell-stimulation platform, capturing high-voltage waveforms and adding a live GUI for parameter control (https://github.com/nmz787/culture_shock/blob/master/DEVELOPER_NOTE.md#debug-setup).  
- A Cell paper on tDCS in macaques was circulated, showing that trans-cranial direct-current stimulation accelerates associative learning and alters functional connectivity; full-text links were provided via ResearchGate and sci-hub.  
- jrayhawk shared a patent (US20120141610) noting that Sarracenia purpurea extract strongly inhibits CDK-dependent viruses (CMV, HPV, HSV, HIV, smallpox), suggesting a broad-spectrum antiviral lead.  
- IEEE Spectrum coverage of an “ultrasound-on-a-chip” handheld imager priced at ~US$2 k was discussed, with speculation on its profit margins and disruptive potential for medical diagnostics.  
- opnwatr.io’s wearable holographic fNIR system (from ex-Pixel Qi engineers) was introduced; debate followed on whether it performs true imaging or simply extracts fast optical signals, plus skepticism about LCD modulation speed for time-of-flight sensing.  
- fltrz documented a DIY gamma-ray detector build: a metal can converted to a disc-shaped housing with aluminum-foil window, BNC feed-through, and dead-bug op-amp circuitry for compact radiation counting.  
- fltrz also detailed the mechanical restoration of a 3-speed bicycle planetary-gear hub—cleaning, lubrication, spoke replacement (38 spokes in a crossed pattern), and wheel truing—framed as an exercise in modular arithmetic and factory-jig empathy.
