Open-source camera could revolutionize digital photography

Stanford scientists’ open-source camera could change photography by giving programmers anywhere the power to change camera features and create new possibilities.
Stanford photo scientists are out to reinvent digital photography with the introduction of an open-source digital camera, which will give programmers around the world the chance to create software that will teach cameras new tricks.
Marc Levoy, professor of Computer Science and of Electrical Engineering and graduate student Andrew Adams with the open source camera.
If the technology catches on, camera performance will be no longer be limited by the software that comes pre-installed by the manufacturer. Virtually all the features of the Stanford camera – focus, exposure, shutter speed, flash, etc. – are at the command …

New material for nanoscale-computer chips

New data from Chinese-Danish collaboration shows that organic nanoscale wires could be an alternative to silicon in computer chips. The discovery has just been published in the respected scientific journal, Advanced Materials.
Nanochemists from the Chinese Academy of Sciences and the Nano-Science Center, Department of Chemistry have developed nanoscale electric contacts out of organic and inorganic nanowires. In the contact they have crossed the wires like Mikado sticks and coupled several contacts together in an electric circuit. In this way they have produced prototype computer electronics on the nanoscale.
Alternative to silicon computers
Today the foundation of our computers, mobile phones and other electronic apparatus is silicon transistors. A transistor is in principal an on- and off- contact …

Semiconductors for Cool Computers

Computers with no need of cooling? They haven’t come into existence yet.
However, physicists of the University of Würzburg are paving the way for them: In the American scientific journal “Science”, the researchers now present a semiconductor that transmits electric current without heating up in the process.
This new type of semiconductor consists of mercury telluride and mercury cadmium telluride. In a sophisticated procedure, the Würzburg physicists apply these two materials to penny-sized crystal wafers in alternate ultra-thin layers. “The individual layers are only seven to ten nanometers thin,” says Professor Laurens Molenkamp. In other words, inconceivably fine: A nanometer is one millionth of a millimeter.
Tiny wire fabricated
In order to analyze the conductivity of the layered material, …
