- A participant with severe eczema raised the possibility of a DIY gene-therapy patch to restore expression of the skin-barrier protein filaggrin, noting that transient expression on a low-stakes area (e.g., lower-leg skin) could be tested first.  
- kanzure pointed out that skin is easily accessible for transfection with PEI (polyethylenimine), making topical gene delivery technically feasible for such an experiment.  
- LulzBot and FluidForm announced a collaboration to integrate open-source 3-D bioprinting hardware with FluidForm’s FRESH (Freeform Reversible Embedding of Suspended Hydrogels) technique, potentially lowering the barrier to entry for tissue-engineering labs.  
- crowdAI, a platform that hosted machine-learning competitions for open science, was reported to be shutting down after only seven blog posts, highlighting the fragility of volunteer-driven open-science infrastructure.  
- A 2013 paper describing a brain-to-brain interface that lets a human control a rat’s tail movement via EEG-detected motor imagery and focused ultrasound was resurfaced, illustrating early non-invasive BCI-to-peripheral-actuator experiments.
