Researchers hope this discovery with honeybees may open the way for new disease-detection tools based on biological systems and scent analysis.
Have you ever heard of a bee sniffing out cancer? Believe it or not, honeybees can detect lung cancer in human breath.
This isn’t the first time scientists have explored animals’ amazing olfactory abilities for cancer detection. Previous studies have demonstrated that trained canines, rats, insects, and even nematodes may detect cancer.They created a special recipe for a “synthetic breath mixture.” This mixture resembled the chemical composition of a healthy person’s breath and that of someone with lung cancer.
Interestingly, researchers observed a difference in honeybee’s neural firing rates when exposed to the odors. The team saw honeybees activating multiple distinct neurons in their brains, which helped them distinguish between synthetic lung cancer breath and healthy breath.
