Researchers develop light transistor
TU Vienna has managed to turn the oscillation direction of beams of light – simply by applying an electrical current to a special material. This way, a transistor can be built that functions with light instead of electrical ...

New nanomechanical oscillators with record-low loss
The vibrational modes of nanomechanical resonators are analogous to different notes of a guitar string and have similar properties such as frequency (pitch) and lifetime. The lifetime is characterized by the quality factor, ...

Study finds more stable clocks could measure quantum phenomena, including the presence of dark matter
The practice of keeping time hinges on stable oscillations. In a grandfather clock, the length of a second is marked by a single swing of the pendulum. In a digital watch, the vibrations of a quartz crystal mark much smaller ...

Middle atmosphere in sync with the ocean
Water plays a major role for our planet not only in its liquid form at the surface. In the atmosphere too, it considerably affects our lives as well as weather and climate. Clouds and rainfall are one example. Water vapor, ...
