Only folks who have undergone an endoscopy can understand the trauma of shoving a tube down the throat to hunt for ulcers or other gastro problems. To save patients from related discomfort and uncomplicated diagnosis of digestive ailments, Russian gastroenterologists are now resorting to electronic nose. Such a nose can sniff out a range of diseases and check the quality of food too. This non-invasive technology works by taking microbes from the human tongue and then special sensors can sniff out whether there is abnormal activity in the stomach. Apart from detecting infections in human body, such a device is also used to sniff out additives in food and to see just how fresh a product is. Akin to a very ultra sensitive version of human nose.

Already successful in Europe and U.S., such a sniffing nose is now cropping up in Voronezh, Russia.
