- The channel debated the feasibility of non-invasive high-resolution brain imaging for connectome-scale mapping; current CT scanners (~0.2 mm) would need a ~200× sensitivity boost to reach the ~1 µm axon scale, and micro-CT or nanoCT were mentioned but questioned for safety and practicality.  
- A long-term “evil plot” was outlined for using phased-array ultrasound as a non-invasive brain-stimulation and tumor-ablation platform, motivating interest in open-source ultrasound hardware.  
- Two open-source ultrasound projects were reviewed: the Paris-based EchOpen initiative (echopen.org) and the Murgen dev-kit (github.com/kelu124/murgen-dev-kit); both provide single-element analog front-ends rather than full imaging probes, and suggestions were made to add Doppler, 3-D scanning, or piezo-array upgrades.  
- A Google Doc proposal for an ultrasound imaging project was circulated for technical review, focusing on hardware BOM cost reduction and avoiding duplication of Murgen’s work.  
- nmz787_i proposed a speculative neural-interface scheme using RF-excitable metalloproteins that would home to specific neurons, enabling wireless stimulation or recording without nanobots.  
- kanzure reported likely participation in the next Human Genome Synthesis Project meeting, indicating ongoing involvement in large-scale open biotech initiatives.  
- Luxembourg’s new space-resources law (spaceref.com/news/viewpr.html?pid=48801) was noted as a legal framework for future asteroid-mining ventures.  
- A searchable Panama Papers database link was shared (Hacker News item 11664322) for investigative transparency.  
- The community lamented the lack of standards and documentation in open-source hardware, arguing that poor interoperability leads to duplicated effort and “houses built on sand.”
