Earth’s magnetosphere, once thought to have a simple electric polarity pattern, has revealed a surprising twist. New satellite data and advanced simulations show that the morning side of the ...

Rub a balloon on your hair and the balloon typically picks up a negative electric charge, while your hair goes positive. But a new study shows that the charge an object picks up can depend on its ...

The fact that like charges repel and opposites attract is basic electromagnetism. But for decades scientists have occasionally made a counterintuitive, and controversial, observation: similarly ...

A research team from the University of Basel, Switzerland, has developed a new molecule modeled on plant photosynthesis: under the influence of light, it stores two positive and two negative charges ...

A ‘hole’ arises due to a missing electron in the valence band, which normally participates in covalent bonding between atoms. The absence of an electron creates a local absence of a negative charge, ...
