• Stanford bioengineers unveiled a 20-cent, hand-powered “paperfuge” blood centrifuge inspired by a whirligig toy; the device spins at 125,000 rpm and separates plasma in under 90 seconds, continuing the ultra-low-cost diagnostics trend started by the Foldscope team.  
• Discussion of the paperfuge’s potential as a covert exercise device was jokingly raised, highlighting the overlap of frugal science and behavioral nudges.  
• A member asked for inexpensive, optically clear, sticky-back films suitable for sealing microscope samples; a smartphone screen protector was suggested as a readily available substitute.  
• Link shared: “Staying awake: top-down systems control of sleep,” an open-access review on neural circuits governing wakefulness and their implications for cognitive enhancement and sleep-hacking.  
• xkcd comic #1782 (“Team Chat”) was circulated, poking fun at the fragmentation and noise of modern group-messaging tools—relevant to the channel’s own coordination challenges.
