Usually, LEDs only emit light of one colour — monochromatic. But a new study — conducted by Dresden-Rossendorf Research Institute — shows that adding a certain rare earth metals can allow them to switch between two colours. This new LED is made from a layer of semiconducting silicon and a layer of insulating silicon dioxide. [...]

Superconductor is no more part of research world only. A project named Hydra will install superconducting power line under midtown New York. The objective, among others, is to build more resilient power grid capable of withstanding lightning strikes and even terrorist attacks. The first stage will connect two substations in Manhattan using high-temperature superconducting cabling [...]

“Aedes is a beauty,” David Severson said. “Only an entomologist can love them and say: OK, that’s really a good-looking mosquito.” Severson of the University of Notre Dame in Indiana is one of the researchers who have just published the genome of the mosquito species Aedes aegypti — best known as mass killer who spreads diseases, [...]

New Scientist Reported: A development that could advance of the hottest areas of physics research has been announced by US scientists: spintronics. Spintronics is the operation of logic devices based on manipulating and measuring the spin of electrons, rather than turning current on and off. It is expected to enable smaller, faster and less power [...]

Core 2 is an eighth-generation x86 architecture microprocessor produced by Intel. Core 2 was to mark the retirement of Intel’s Pentium brand name that had been used since 1993. Core 2 saw the reunion of Intel’s notebook and desktop product lines, which had diverged with the Pentium M and Pentium 4 in 2003. Like the Intel [...]
