Scientists in the Arctic are catching the exhaled breaths of whales to better understand their health. How? Drones. Whales breathe through their blowholes, which are the equivalent of nostrils on their heads. By studying the microbes in exhaled whale breaths, scientists are piecing together how deadly diseases spread in whale populations. Host Emily Kwong and producer Berly McCoy talk to All Things Considered host Juana Summers about what scientists can do with this information, from reducing stress on whales and monitoring ocean health to warning people who could be in close proximity to whales carrying zoonotic diseases.  Interested in more science on charismatic megafauna?
