- A second PCR Hackathon is scheduled for March 24, 2013, aiming to refine the open-source light-bulb PCR machine built during the first event and optionally add a dry heating block or “smart” incubator; participants must RSVP via a Google Form and bring their own power supplies, temperature sensors, and Arduinos.  
- Discussion of Nanoscribe’s two-photon polymerization 3-D printer highlighted its ability to fabricate sub-micron structures, including diffractive pillar arrays for full-color holograms, though cost and practical limitations were noted.  
- Mozilla’s remote debugging protocol for Firefox was dissected: the JSON-over-TCP interface can be enabled in about:config, listens on a configurable port, and reportedly now supports DOM node inspection and highlighting; source locations and usage examples were sought.  
- CircuitLab was criticized for marketing itself as an “open, standard platform” despite being a closed, web-based circuit simulator that still imposes platform lock-in.  
- A WebGL visualization of an fMRI study that maps cortical blood-flow changes to WordNet semantic categories was shared, along with its explanatory blog post, illustrating efforts to decode thought patterns from neuroimaging data.  
- Paperbot successfully retrieved several pay-walled articles, including a 1979 study on calcium-dependent bacteriophage DNA infection and a 2010 paper on genetics and intelligence, demonstrating ongoing use of the channel’s automated literature-sharing tool.  
- PyData conference attendance was mentioned, with participants observing laptop screens during workshops as an informal metric of community interests.
