- MIT’s Camera Culture Group released a femtosecond-imaging system that can “look around corners” by capturing scattered light, with project details at http://web.media.mit.edu/~raskar/femto/.  
- A MakerBot was shown milling PCBs, demonstrating low-cost open-source hardware moving into circuit-board prototyping: http://www.robosavvy.org/forum/viewtopic.php?p=28972.  
- Discussion of DIY AFMs noted the TT-AFM kit priced at US $17,950, highlighting the gap between commercial nano-instrumentation and community budgets.  
- kanzure posted a 30-item list of nootropics and neural enhancers—including piracetam, aniracetam, lion’s mane mushroom, cerebrolysin, selegiline, and GHB—sparking debate on legality and efficacy.  
- Community members reported positive experiences with choline, piracetam, ginkgo, 5-HTP, tyrosine, and melatonin for cognitive and mood support.  
- A brief exchange questioned whether Eri Gentry (of genomera.com) was running a “butter study,” linking citizen-science genomics with quantified-self experimentation.  
- QuantumG and kanzure discussed surface-reconstruction algorithms for CSG models in the lolcad project, focusing on nearest-neighbor methods for sparse point clouds.  
- fitzsim and kanzure debated migrating the NanoEngineer-1 wiki from MediaWiki to ikiwiki to keep documentation in the same git repository as the code, weighing web-editing comfort against version-control integration.
