  "account": "A team of researchers at Ohio State University have developed a device that can transmit scents over the internet, potentially adding a new dimension to virtual worlds and long-distance communication. The technology relies on an electronic nose, or \"e-nose,\" and a smell generator, connected via machine learning algorithms. The e-nose consists of metal oxide sensors that react to specific molecules in different smells, creating unique electrical signals. After training the AI on the reactions of five common smells, including orange, cake, coffee, beer, and red wine, the system can recreate these odors when sent over the internet. A prototype device, called \"Scentronic,\" uses atomisers and liquid containers to release scents, while a taste-imitating version involves a cup of water with flavoured liquid. Early tests showed 73% accuracy for scent transmission to volunteers. Potential applications include enhancing virtual reality experiences, improving food rations for soldiers or astronauts, and aiding medical diagnoses related to olfactory impairments.",
