- A new eLife paper (https://elifesciences.org/articles/24364) was highlighted for using electron-microscopy connectomics to trace axonal targets and infer circuit dynamics in a sequence-generating neural network.  
- Sci-Hub link (http://sci-hub.tw/10.1126/scirobotics.aav4317) was shared to a Science Robotics article on magnetically actuated microrobots designed as a delivery platform for stem-cell transplantation.  
- Discussion referenced a Brain Stimulation journal article (https://www.brainstimjrnl.com/article/S1935-861X(19)30102-0/fulltext) that maps transcranial direct-current stimulation (tDCS) current flow inside the brain using MRI, with follow-up questions about extending the technique to transcranial alternating-current stimulation (tACS) up to ~50 Hz.  
- A Nature Medicine paper (https://www.nature.com/articles/s41591-019-0485-4) was introduced; meta-omics analysis of elite athletes identified a performance-enhancing gut microbe that boosts exercise capacity via lactate metabolism, prompting tongue-in-cheek speculation about probiotic/propionate sports drinks.  
- Brief philosophical and technical tangents touched on human behavioral classification in perception-space, the smell of pyrolized gunpowder as a stimulus, and the (nonexistent) term for re-naturing dislocated calcium phosphate matrices in bone.
