Bees Can Smell Cancer, MSU Researchers Say
Greetings, Environmental Activists and Concerned Citizens,
Researchers at Michigan State University have made a groundbreaking discovery: honeybees possess the ability to detect chemicals associated with lung cancer in human breath. Their study demonstrates that honeybees can discern between different types of lung cancer cells with remarkable precision.
The Research Breakthrough
Dr. Debajit Saha, an assistant professor in MSU’s College of Engineering, and his team conducted experiments using synthetic breath mixtures that mimic the chemical composition of healthy human breath and breath from individuals with lung cancer. This research, led by doctoral candidate Michal Parnas and lab manager Elyssa Cox, involved exposing honeybees to these synthetic mixtures.
"We tested the synthetic lung cancer versus healthy human breath mixtures on approximately 20 bees," Cox explained. "We designed a custom 3D-printed harness to hold a live honeybee while we attached a small electrode to its brain to monitor its neural signals."
Honeybee Sensory Abilities
The study revealed that honeybees can detect extremely small concentrations of cancer-indicating chemical compounds. They could distinguish minute changes in chemical concentration, down to parts per billion, in the synthetic breath mixtures.
"We pass these odors on to the antenna of the honeybees and record the neural signals from their brain," Dr. Saha explained. "We observed a distinct change in the honeybee’s neural firing response."
Implications for Cancer Diagnosis
According to the research team, this discovery could pave the way for new diagnostic methods for lung cancer that are quick, noninvasive, and highly specific. Autumn McLane-Svoboda, a graduate student involved in the study, highlighted the potential impact of their findings.
"The future implications for this are huge as our sensor could allow for patients to receive specific cancer diagnoses quickly which is imperative for correct treatment routes," McLane-Svoboda said.
Future Directions
Dr. Saha’s team is now focused on developing a noninvasive lung cancer test that simply requires patients to breathe into a device. The sensor inside, based on the honeybee brain's detection capabilities, would analyze the presence of cancer-related chemicals and provide immediate results.
"This work opens the door for more biological and smell-based disease detection technologies," Dr. Saha stated.
Conclusion
Published in the journal Biosensors and Bioelectronics, this research showcases the remarkable potential of honeybee sensory abilities in medical diagnostics. By harnessing nature’s own sensors, researchers at MSU are pioneering a new frontier in disease detection.
