NASA's Mars helicopter completes flight tests

Since the Wright brothers first took to the skies of Kill Devil Hill, North Carolina, Dec. 17, 1903, first flights have been important milestones in the life of any vehicle designed for air travel. After all, it's one thing ...

Mathematical models explain how a wrinkle becomes a crease

Wrinkles, creases and folds are everywhere in nature, from the surface of human skin to the buckled crust of the Earth. They can also be useful structures for engineers. Wrinkles in thin films, for example, can help make ...

Computer model predicts red blood cell flow

Adjacent to the walls of our arterioles, capillaries, and venules—the blood vessels that make up our microcirculation—there exists a peculiar thin layer of clear plasma, devoid of red blood cells. Although it is just ...

Scaling up polymer blobs

Scientists use simulations to test the limits of their object of study—in this case thin films of polymers—to extremes of scale. In a study about to be published in the European Physical Journal E, Nava Schulmann, a researcher ...

Glass has potential to be stronger, researchers say

(Phys.org)—Glass is strong enough for so much: windshields, buildings and many other things that need to handle high stress without breaking. But scientists who look at the structure of glass strictly by the numbers believe ...

High-tech wound dressing fights infection in mouse trial

(Phys.org) -- An ultra-thin layer of polymer impregnated with a surgical anti-bacterial aided healing by preventing infection in a mouse study performed at the University of Wisconsin-Madison.
