Gold supraballs trap almost all sunlight. “This results in ~90% absorption across the solar spectrum” by stacking self-assembling gold nanospheres into textured coatings that soak up UV, visible, and near-infrared, then turn it into heat for thermal devices. The payoff: […]
Influencing dreams. “Another dreamer was cued with a puzzle about jungles and woke up from a dream in which she was fishing in the jungle thinking about that puzzle.” Northwestern researchers played puzzle-specific soundtracks during REM sleep and got 75% […]
Wellness is losing meaning. “Wellness feels like it’s losing all meaning in health tech.” Oura is lobbying for a new “digital health screener” category so more wearable features could skip FDA clearance, but the wellness vs medical device line is […]

A community collection of OpenClaw use cases. Is an AI bot really useful? In many ways, it can be! It’s nice to see how others apply it. PLEASE be super careful and paranoid about this whole category of product as […]
WiFi pose detection is now open source. “Output: real-time pose, breathing rate, heart rate, presence, room fingerprint. No cameras. No wearables. No Bluetooth beacons. Just WiFi signals you’re already swimming in. It sounds like magic. It’s not. It’s physics that’s […]
Naked swim class. “What seemed perfectly normal to one generation often becomes head-shaking at the very least and scarcely believable to later generations.” A writer remembers mandatory nude swimming in mid-1960s high school gym class, and the odd logistics that […]
