- A tweet from Dan Bumbarger was shared showing a “Frankenstein” imaging rig expected to generate 25 TB/day of cortex-connectivity data, highlighting the scale of emerging brain-mapping efforts.  
- Ed Boyden’s expansion-microscopy image of the kidney glomerular filtration barrier was circulated, illustrating the technique’s sub-diffraction resolution for biological samples.  
- The channel discussed theoretical limits of spatial addressing: whether 10¹³ independently controllable elements with millisecond response is physically plausible, noting that commercial micromirror arrays and 30-megapixel CMOS sensors provide current density benchmarks.  
- Literature gaps were noted—existing CMOS electrode arrays top out at ~20–60 k electrodes, far below the density already achieved in imaging sensors, prompting questions about manufacturability bottlenecks.  
- A 1994 paper on “High-speed polymerase chain reaction in constant flow” was dug up as a possible route to faster, parallel DNA amplification.  
- Eric Drexler and Adam Marblestone’s Open Philanthropy report (public version) was linked, covering scalable brain–interface architectures and molecular manufacturing roadmaps.  
- Cosmos Magazine articles on how human memories are formed and how the brain actively blocks recall were shared, underscoring interest in both memory encoding and erasure mechanisms.  
- A Wired overview of “What’s next for CRISPR” was posted, summarizing 2017 advances and near-term therapeutic prospects.  
- ArXiv pre-print “Advances in macromolecular data storage” was highlighted; it describes using an STM to flip individual nucleotide states for ultra-dense archival storage.  
- GitHub project “DNA” (allanino/DNA) was introduced—a Python toolkit for encoding arbitrary computer files into DNA sequences, alongside discussion of QR-code-based codecs for similar purposes.
