- A free, high-resolution embryology atlas for the house mouse was shared: “The House Mouse Atlas of Embryonic Development” (download link provided) along with the EMAP gene-expression mapping project and the suggestion of using Ken Brakke’s Surface Evolver to simulate epithelial packing as soap-bubble-like surface minimization.  
- Participants debated how best to store and share quantitative engineering data, comparing spreadsheets, YAML, Semantic MediaWiki, and custom Python classes; a 2-hour effort to compile battery specifications (18650 vs. 14500 vs. AA) was used as the test case.  
- Links to several open-source geometry and CAD resources appeared: Regli’s Drexel design-repository, OpenCASCADE tutorials and blog, SolidWorks assembly-mate tutorials, and the disappearance of the OCC 5.1 “part-mating” class.  
- Reeb graphs and contour trees were highlighted as powerful tools for 3-D shape matching and skeleton extraction; pointers to IEEE papers, Pascucci’s contour-tree library, and Blender’s Reeb-graph-based skeleton generator were supplied.  
- Quantities libraries for Python (quantities, magnitude) were recommended for unit-aware calculations, and Algorithm::Dependency / topsort were noted for dependency resolution in CAD pipelines.  
- DIY-bio news: the San Francisco “glow-in-the-dark” meetup write-up on diybio.org was circulated.  
- Hardware links included Lockheed Martin’s new HULC exoskeleton press release, Sakura’s 340 cm bipedal Land-Walker exoskeleton, PCB-Motor’s flat piezoelectric motors, and 50 nm-accurate ultrasonic motor stages.  
- A quick recipe for a sub-$100 nanopositioning stage was recalled: quartering a piezo buzzer from a headphone to obtain four independent actuators.
