NPR's Short Wave team presents three compelling scientific discoveries this week. The first segment investigates the neurological impacts of air pollution, examining research linking particulate exposure to cognitive decline and memory impairment. The second story delves into paleobiological analysis of fossilized squirrel excrement, which preserves botanical evidence from prehistoric eras through embedded seeds and pollen.
The final segment examines deep-sea taphonomy, specifically the formation of cetacean bone beds where whale remains accumulate over millennia. These natural depositional sites offer researchers valuable windows into marine ecosystem dynamics and nutrient cycling in abyssal environments.
