- Anders Sandberg and Meredith Patterson hosted a Reddit AMA on knot theory and the combinatorics of neck-tie knots, revealing an unexpected collaboration between the two researchers.  
- A new Nature Scientific Reports paper titled “Building an organic computing device with multiple interconnected brains” was shared, describing multi-brain neural interfaces for emergent computation.  
- Detailed reverse-engineering of the open-source POSaM microarray printer continued: example timing playbooks (30-second dry/wash/deprotection steps, 0.7-second acetonitrile dispense) and messy Visual-Basic source were analyzed, with plans to contact original developer Chris Lausted.  
- Extensive discussion of NCBI RefSeq/GenBank mirror inconsistencies: multiple FTP mirrors (hgc.jp, vbi.vt.edu, bio-mirror.net) were found to have missing or zero-byte genome assemblies; participants began cross-mirror diffs and urged NCBI to fix replication errors.  
- Links to open tools and datasets were circulated: planar-mechanism kinematic simulator PMKS, Asimov’s short story “Nightfall,” NASA’s “Orbiting Rainbows” optical-aerosol space-construction concept, and the crowd-funded black-rhinoceros genome-sequencing project on experiment.com.
