How male dragonflies adapt wing color to temperature

New research from Case Western Reserve University in how dragonflies may adapt their wing color to temperature differences might explain color variation in other animals, from lions to birds.

Toward urban air mobility: Air taxis with side-by-side rotors

In this high-resolution visualization of NASA's side-by-side, intermeshing rotor air taxi concept, researchers are working to understand complex rotor air flow interactions, simulated using high-fidelity computational fluid ...

Unique study shows how bats manoeuvre

For the first time, researchers have succeeded in directly measuring the aerodynamics of flying animals as they manoeuvre in the air. Previously, the upstroke of the wings was considered relatively insignificant compared ...

Why don't birds fall over when they jump?

Scientists have been analysing the way birds jump when they take-off to help us understand why they simply don't just fall over when attempting to fly.
