Microstructure-induced biomechanical responses of dragonfly wing veins
Wang's research team discovered the sandwich microstructure of dragonfly wing veins1 and recently revealed the organic junction between these longitudinal veins and membranes of the dragonfly wing2. Based on observed mic ...
Space tourism craft reaches glide-test milestone (Update)
High over the Mojave Desert, the stubby-winged SpaceShipTwo bent itself into a near-right angle shape and plunged nearly straight downward for more than a minute before unfolding and gliding to a runway landing ...
Engineer develops new approach for uncertainty estimation, wins award

Whale-inspired ocean turbine blades
Interest in developing alternative energy sources is driving the consideration of a promising technology that uses underwater turbines to convert ocean tidal flow energy into electricity.
Enhancing the efficiency of wind turbines
A milestone in the history of renewable energy occurred in the year 2008 when more new wind-turbine power generation capacity was added in the U.S. than new coal-fired power generation. The costs of producing power with wind ...
Jump rope aerodynamics
Jump ropes are used by kids for fun and by athletes for training. But what about the underlying physics? How do jump ropes work? Can important engineering principles be studied?
Showcase UAV demonstrates 'Flapless Flight'

Feathered friends: Ostriches provide clues to dinosaur movement
Once thought to be "evolutionary leftovers", new research has shown that ostriches in fact use their feathered forelimbs as sophisticated air-rudders and braking aids.
The Next Big Wave
Dan Bolfing, like energy guru Amory Lovins, thinks the greatest advances in transportation efficiencies can be attained with lighter weight vehicles and better aerodynamics.
