- A proposed low-cost route to carbon nanotubes was floated: ferrocene + thiophene + methane as feedstock.  
- 1366 Technologies claims a path to $1/W solar cells by texturing multicrystalline silicon, shrinking silver wires to one-fifth normal width, and turning the current-collection bars into faceted mirrors.  
- DNA origami was highlighted as a working example of nano-scale self-assembly, with a real-world demo of the Nanorex logo and the observation that even top labs still rely on manual pipettors.  
- Nanorex, the 3-D nanotech CAD package used in the demo, was noted to be GPL-licensed.  
- A “Baez dump” project was underway: systematically archiving all 180+ weekly research digests (1992-present) of mathematical physicist John C. Baez plus every paper he cites, motivated by long-term preservation.  
- Discussion of self-replication centered on the idea of a self-replicating AFM / scanning-probe-lithography tip, with rough notes posted to the channel wiki.  
- Henry Markram’s Blue Brain project—400 computational-neuroscience packages running on IBM Blue Gene supercomputers to simulate a mouse neocortical column—was linked to a newly spotted paper on valproic acid and autism.  
- A pathology wiki page was started as a “debugging guide” for human biology, with plans to import bio-ontologies and render them as Graphviz diagrams.
