Never mind space, the ocean remains humankind's final frontier, and thanks to several emerging technologies there's never been a better time to get wet and start exploring. The latest generation […]

Good footwork is the secret of winning in a variety of sports ranging from hockey to tennis. Athletes who would want to improve their footwork should engage in such simple exercises as jumping rope and stair climbing to gain balance and control.

Eye-hand coordination is crucial in such sports as baseball or basketball. However, specific eye-hand coordination skills required in one specific sport does not necessarily translate to the same level of proficiency in other sports. Tips on improving eye-hand coordination are presented.

Runners should pay particular attention to the type of surface they run over. Harder surfaces tend to stress the bones and joints while softer surfaces tend to strain tendons and ligaments. To prevent such strains and injuries, it is best to vary the surfaces worked out on.

An experimental panel that encapsulates silica powder within vacuum chambers may provide a new insulation option for refrigerators and houses. Several models of the panels have been designed, using metal [...]
