If you thought bees were just useful for making honey, think again.
According to a Portuguese scientist Susana Soares, bees can be trained to sniff out cancer. And what's more, the bees can be taught in just 10 minutes.
Susana invented a two-chambered glass dome that uses bees to sniff out cancer.
"The glass objects have two enclosures: a smaller chamber that serves as the diagnostic space and a bigger chamber where previously trained bees are kept for the short period of time necessary for them to detect general health," she explains on her website.
"People exhale into the smaller chamber, and the bees rush into it if they detect on the breath the odor that they were trained to target."
