Modern telecommunications happens because of fast electrons and fast photons. Can it get better? Can Moore's law—the doubling of computing power ever 18 months or so—be sustained? Can the compactness (nm-scale components) ...

The strong winds of a tropical cyclone whip up the sea surface, driving ocean waves a dozen meters (about 40 feet) high. When one such ocean wave runs into another wave that has an equal period but is traveling in the opposite ...

(Phys.org)—Metals are known for being good electrical conductors. Due to this property, a stationary electric point charge placed outside a metal will cause the electrons in the metal to redistribute in such a way that ...
(Phys.org)—Magnetism may be one of the most fundamental concepts in physics, but under the surface, magnetism holds complex secrets that scientists are still trying to unravel. One of these areas involves the dynamics of ...
A new approach to invisibility cloaking may one day be used at sea to shield floating objects – such as oil rigs and ships – from rough waves. Unlike most other cloaking techniques that rely on transformation optics, ...

Engineers and city planners study surface geology in order to construct buildings that can respond safely to earthquakes. Soft soil amplifies seismic waves, resulting in stronger ground motion than for sites built over bedrock. ...

It's known that large quakes trigger smaller quakes hours later as the strong seismic waves pass through the Earth. USGS and UC Berkeley seismologists have now shown that at least some large quakes – strike-slip as opposed ...
