Humans with an appreciation of beauty may have marveled for millennia at the artistry of a darting hummingbird, but scientists announced today that for the first time they can more fully explain how a hummingbird can hover.
Using a powerful technology that was originally developed for engineering, researchers were able to exactly document the movement of air around a hummingbirds wings and show how its flight is accomplished with the body structure of a bird but some of the aerodynamic tricks of an insect.
This gives it an ability to hover almost indefinitely - an evolutionary advantage in feeding on plant nectar that no other bird has - and an elegance that has charmed people for generations.

Augsburg chemists present a new technology for compressing, storing and transporting highly volatile gases in porous frameworks/New prospects for gas-powered vehicles
Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...
When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
