A twin-beam flashlight spots microplastics in a split second. Physicists have assembled a compact device where one half of the light pulse probes the sample in invisible infrared, and the other reports the result to a standard camera. A pocket-sized pollution detector for any stream or beach is no longer science fiction.
🎯 Every liter of bottled water contains about 240,000 microplastic particles on average—twice as many as tap water.
🎬 A real-life tricorder from Star Trek: it figures out what an object is made of in a second.
