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 ...

Explained: How does a soccer ball swerve?

It happens every four years: The World Cup begins and some of the world's most skilled players carefully line up free kicks, take aim—and shoot way over the goal. The players are all trying to bend the ball into a top corner ...

Programming drones to fly like birds

(Phys.org) —Jack Langelaan's lab in the basement of Hammond Building is a model airplane builder's dream. In one room, graduate students Nathan Depenbusch and John Bird test algorithms on commercial flight simulators: Pilot's ...

Study shows how water dissolves stone, molecule by molecule

Scientists from Rice University and the University of Bremen's Center for Marine Environmental Sciences (MARUM) in Germany have combined cutting-edge experimental techniques and computer simulations to find a new way of predicting ...

Researchers say a comet killed the dinosaurs

In a geological moment about 66 million years ago, something killed off almost all the dinosaurs and some 70 percent of all other species living on Earth. Only those dinosaurs related to birds appear to have survived. Most ...

MASSIVE advances in aerodynamics

Engineers are closer to understanding, and therefore manipulating, invisible aerodynamic drag forces, that cause an estimated 50 per cent of transportation fuel to be lost before we can use it.
