- Foundry Group’s investment in MakerBot Industries (reported at http://www.feld.com/wp/archives/2011/08/foundry-group-invests-in-makerbot-industries.html) was highlighted as a milestone for open-source 3-D printing and the DIY hardware ecosystem.  
- Halcyon Molecular was noted to have pivoted from DNA-sequencing nanotech to “uploading,” prompting criticism that longevity research was being sidelined.  
- Discussion of brain-slicing for whole-brain emulation referenced Todd Huffman’s 3scan project as one of the few visible efforts using vibratomes sized for human brains.  
- A request circulated for photographs or specifications of a human-brain-scale vibratome to support neuroanatomy and connectomics work.  
- Practical centrifuge math was raised: balancing a 20 000 g ultracentrifuge when the rotor is off-center by 1 g, with an implicit query about cost-effective sourcing of such machines.  
- Channel infrastructure problems were reported: the biohack.sourceforge.net wiki and archives were offline, acknowledged as a temporary outage by the maintainer.
