"Scientists have created the first lasers made entirely from edible materials," reports Science magazine "which could someday help monitor and track the properties of foods and medications with sensors that can be harmlessly swallowed." [The researchers' report] shows that tiny droplets of everyda, Researchers have developed edible sensors made from glowing, biocompatible liquid droplets. These sensors, which can be consumed and excreted, could revolutionize food and drug monitoring. They utilize bioluminescence, emitting light in response to specific stimuli like changes in pH, temperature, or the presence of certain compounds., Scientists have created the first lasers made entirely from edible materials, which could someday help monitor and track the properties of foods and medications with sensors that can be harmlessly swallowed., Soap bubbles can be turned into lasers and these bubble lasers are exceptional at sensing electric fields and pressure. A laser needs three key parts., An innovation by scientists at the California Institute of Technology (Caltech) could change that, delivering a laser capable of producing ultrashort pulses that can fit on a fingertip., .
