- A new neurofeedback protocol for depression was shared: http://www.redalyc.org/pdf/172/17217456034.pdf.  
- DIY biology safety was discussed via a Science Magazine survey showing no harm beyond “damage to the power of institutional science.”  
- Brain-preservation competition details were posted: http://www.brainpreservation.org/competitors/.  
- Two microbiology papers were circulated—one on “viable but non-culturable” human bacterial pathogens (Frontiers in Microbiology, 2014) and another on using H₂¹⁸O stable-isotope probing to profile active soil microbes (PMC4398504).  
- A hobbyist laser-safety debate arose around using lasers to convert brown eyes to blue by ablating iris pigment; links to the long-standing “Sam’s Laser FAQ” (repairfaq.org/sam/laserlir.htm) were provided.  
- High-altitude cognitive enhancement was explored: maaku asked whether nootropics (e.g., phenylpiracetam, coca leaves) or cocaine analogs could counter hypoxia-induced mental impairment on Everest, and proposed retro-1996 radio-beacon navigation systems for whiteout conditions.  
- RNA-interference and enhancement ideas were floated, including reversible RNAi drugs and inducible transcription-factor activation.  
- Community infrastructure notes: Aurelius_Home offered private GitLab hosting, while kanzure critiqued GitLab’s commit-order display and documentation quality.
