Science: Wildfire Smoke Threatens Ozone Layer, Tick Bite mRNA Vaccines

Could wildfires be depleting the ozone all over again? Staff Writer Paul Voosen talks with host Sarah Crespi about the evidence from the Polarstern research ship for wildfire smoke lofting itself high into the stratosphere, and how it can affect the ozone layer once it gets there.

Next, we talk ticks—the ones that bite, take blood, and can leave you with a nasty infection. Andaleeb Sajid, a staff scientist at the National Cancer Institute, joins Sarah to talk about her Science Translational Medicine paper describing an mRNA vaccine intended to reduce the length of tick bites to before the pests can transmit diseases to a host.
