Episode Details

A high-tech pollen catcher on the roof of Dartmouth Hitchcock Medical Center is revolutionizing allergy care in New England, offering hyper-local pollen data instead of relying on distant weather stations. Since launching last spring, Dr. Alex Zajack has been weekly collecting and analyzing airborne pollen under a microscope, identifying species by microscopic details like pine pollen’s Mickey Mouse ear shape. This summer marks the first full season of continuous data, revealing a wet spring that kept pollen levels low — though allergy seasons remain stubbornly similar to last year. The local insights empower doctors to customize treatments and shots, while also feeding long-term research into how climate change may be extending and intensifying pollen seasons. For patients, it’s not just science — it’s personal empowerment.
