Scientists studied how cicadas pee. Their insights could shed light on fluid dynamics
Cicadas, and the way they urinate, offer a 'perfect' lab for understanding fluid dynamics at very small scales, researchers say

Monarch butterflies' white spots may help them fly farther, scientists say
Monarch butterflies with more white spots on their mostly orange-and-black wings are more successful at long-distance migration. Some scientists think the spots may affect airflow around their wings.
