For many years, the power supply voltage required to store charge in a capacitor remained stuck at 1 volt. As computers improved, this limitation made transistors run at increasingly hot temperatures, reducing the machine's efficiency. Researchers in the United States now think they can change this.

Years ago, when Moore's Law first appeared, it predicted that the number of transistors that will be fitted on a computer microprocessor will be doubled once every couple of years. The trick is to do so inexpensively and constantly, and modern technology is beginning to reach the limits of transistor miniaturiza... |

A collaboration of researchers has recently made it possible to accelerate the speed of the basic light particle – the photon – to seemingly faster-than-light speeds. This effect has been achieved by passing the photons through stacked materials, in which the scientists added a single, thin layer at a str... |

The “dielectric confinement effect,” first proposed in 1979 by scientist L. V. Keldysh, has finally been confirmed with measurements conducted by a team of researchers from the Harvard School of Engineering and Applied Sciences (SEAS), working together with colleagues from the Worcester Polytechnic Instit... |

The new invention, which harnesses the power of light to convert it into mechanical energy, was designed and demonstrated by a team of Japanese researchers, who have proven that they could provide solutions to the mechanical controls that cannot use electric motors. The prototype was built by the Japanese physicist H... |
