(Phys.org) —When hydrogen is produced from water during electrolysis, some energy is lost as tiny bubbles. In a new study, researchers have demonstrated that 25-nm transistors—so small that they're considered zero-dimensional ...
How fast can electronics be? When computer chips work with ever shorter signals and time intervals, at some point they come up against physical limits. The quantum-mechanical processes that enable the generation of electric ...

(Phys.org)—A team of researchers working at the University of Konstanz, in Germany is claiming to have directly sampled electric-field vacuum fluctuations, which would be the first ever made. In their paper published in ...
In a legendary account the famous 19th century explorer and naturalist Alexander von Humboldt recounted a dramatic battle between horses and electric eels that he witnessed on a field trip to the Amazon. In the following ...
