- DIY neuro-stimulation: tDCS/tACS is the most accessible route for home users (phosphenes appear at ~1 mA, cortical effects only at higher currents), whereas TMS carries seizure risk and needs a spotter; broad electric fields and high inter-subject variability remain key limitations.  
- Landmark citizen-science case: Hugh Rienhoff’s multi-year open-source sequencing and interpretation of his daughter’s genome to diagnose a rare disease was highlighted as a model for decentralized diagnostics.  
- Cloning quality control: a 2002 MIT study showing ~4 % abnormal gene expression in cloned-mouse placentas resurfaced, prompting questions about how newer cloning or reprogramming techniques compare today.  
- NASA Technical Reports Server (NTRS) released 966 k public documents on 8 May 2013, with 248 k legacy records still under review; bulk wget downloads were discouraged to preserve metadata integrity.  
- Recruiting critique: “talent marketplaces” such as DeveloperAuction demand extensive unpaid work yet yield non-binding offers; participants argued that “cultural fit” language masks bias and advocated anonymized, skill-first screening.  
- Retro-tech revival: a 1991 paper on neural-network-based mosquito identification in flight inspired discussion of modern “photonic fence” laser bug-zappers, comparing coaxial versus phased-array targeting architectures.  
- UK poised to become the first country to legalize mitochondrial-replacement (“three-person IVF”) therapy, immediately triggering transhumanist commentary on “designer babies” and societal implications.  
- Digital-education tipping point: Los Angeles USD’s $30 million shift to 100 % iPad curricula was cited as evidence that digital textbooks are finally displacing paper, despite publisher resistance and high costs; a Pandora-style royalty model for metered textbook access was proposed as a cost-lowering alternative.
