For the first time, two spacecraft in orbit were aligned in formation with millimeter precision and maintained their relative position for several hours without any control from the ground. The ...

Scientists have known for years that birds like geese and ibises gain an aerodynamic advantage from flying in a "V" formation. Now, researchers from Brown University have provided new insights into ...

Using measurements based on northern bald ibises, the model predicted that a follower flying in an optimal position would require about 11% less total mechanical power than a bird flying alone.
