The film explores the concept of electricity, demonstrating how it can be generated through simple experiments such as rubbing different materials together. It explains the basics of electric currents ...

Bits of material levitating against gravity, a stream of water deflected by invisible means, sparks of light appearing out of thin air; with observations like those, it’s a wonder that the early ...

After a year of trial and error, Liyang Chen had managed to whittle down a metallic wire into a microscopic strand half the width of an E.coli bacterium — just thin enough to allow a trickle of ...

Early experiments suggest a patch that delivers harmless electric currents into the skin can thwart certain bacterial infections. However, it has not yet been tested in humans. When you purchase ...
