Portuguese designer Susana Soares has developed a device for detecting cancer and other serious diseases using trained bees. The bees are placed in a glass chamber into which the patient exhales; the bees fly into a smaller secondary chamber if they detect cancer.
Scientists have found that honey bees - Apis mellifera - have an extraordinary sense of smell that is more acute than that of a sniffer dog and can detect airborne molecules in the parts-per-trillion range.
Bees can be trained to detect specific chemical odours, including the biomarkers associated with diseases such as tuberculosis, lung, skin and pancreatic cancer.
how does one train a bee
"The bees can be trained within 10 minutes," explains Soares. "Training simply consists of exposing the bees to a specific odour and then feeding them with a solution of water and sugar, therefore they associate that odour with a food reward."
Once trained, the bees will remember the odour for their entire lives, provided they are always rewarded with sugar. Bees live for six weeks on average.
Did you know that Green Mount Cemetery is one of the oldest rural cemeteries in America. Rural cemeteries were the prototype of city parks and Green Mount predates Central Park by almost 30 years. In fact, many of the city parks in Baltimore that we know of today were once the estates of wealthy Baltimoreans who believed that more places like Green Mount were needed for the people to gather in and enjoy nature.
