NPR's Short Wave team shares three fascinating science stories this week. The first topic examines how air pollution impacts brain health. Researchers have discovered that exposure to dirty air can affect cognitive function and memory. The second story looks at ancient squirrel droppings found in caves. These droppings contain seeds and pollen that reveal information about prehistoric plant life.
Scientists study these droppings to understand past environments. The third segment explores an unusual phenomenon on the ocean floor. Scientists have discovered areas where whale skeletons accumulate over time. These whale graveyards provide valuable insights into marine ecosystems and the cycle of life in the deep sea.
