Honey bees may be able to detect cancer

A U.K research firm Inscentinel, have said that they have  trained  honey bees to detect certain early-stage cancers in humans.Honeybees are known for their exquisitely sensitive sense of smell.Portuguese designer Susana Soares invented a glass device with two enclosures: a small chamber in which the patient breathes into and a larger chamber where trained bees are kept.The bees are trained by exposing them to smell and then feeding them sugar, so they associate the odor with a food .According to mashbale,If these bees detect the odor they were trained to pinpoint they are going to rush into the smaller chamber where the breath is and sniff out that odor .
