Honey Bees Trained to Detect Cancer on Patients' Breath?
Thanks to their super-sensitive sense of smell, bees can detect odors that a human nose can't, Soares explains on her website. Biomarkers associated with tuberculosis, lung cancer, skin cancer and diabetes, which can all be detected through smell, are present on a patient's breath.
Soares designed a glass objects with two enclosures: a small chamber that the patient breathes into and a larger chamber where trained bees are kept. If the bees detect the odor they where trained to pinpoint - in this case that of disease biomarkers - they'll rush into the smaller chamber where the breath is.
