- A new arXiv commentary (1604.01359) was circulated that sharply questions three recent Nature papers on biological magnetism, arguing the reported effects violate basic physics by 5–10 orders of magnitude and suggesting the phenomena—if real—must arise from entirely different mechanisms than proposed.  
- Discussion of magnetically-gated ion channels created by attaching ferritin to an ion channel and actuating it with external magnetic fields was highlighted as a key target of the critique.  
- Sishio asked for practical experience in building haptic interfaces, prompting fenn to share Stanford’s CS235 lecture on cable-driven robot transmissions (YouTube link) and two images of the Salisbury lab’s high-precision haptic devices.  
- The channel’s culture was briefly reflected in JayDugger’s quote: “false! the truth is that everyone is fucking lazy and nobody tries,” offered as a motivational counter to complacency.  
- No other substantive technical threads, papers, or links were introduced during the remainder of the log.
