| Advance Made Toward Communication, Computing at 'Terahertz' Speeds |

Physicists in the United States and Germany have discovered a way to use a gallium arsenide nanodevice as a signal processor at "terahertz" speeds -- the first time it's been used for this purpose and an important step forward in the new world of optical communication and computing. Existing communications and computer architecture are increasingly being limited by the pedestrian speed of electrons moving through wires, and the future of high-speed communication and computing is in optics, experts say. The Holy Grail of results would be "wireless interconnecting," which operates at speeds 100 to 1,000 times faster than current technology. |

NASA Image Of The Day
| Panorama of the East Coast | ||
| This Jan. 29 panorama of much of the East Coast, photographed by one of the Expedition 30 crew members aboard the International Space Station, provides a look generally northeastward: Philadelphia-New York City-Boston corridor (bottom-center); western Lake Ontario shoreline with Toronto (left edge); Montreal (near center). An optical illusion in the photo makes the atmospheric limb and light activity from Aurora Borealis appear "intertwined." Image Credit: NASA... | ||

Technology Quotes of the Day
Information technology and business are becoming inextricably interwoven. I don't think anybody can talk meaningfully about one without the talking about the other.

Brain Quotes of the Day
He who joyfully marches to music in rank and file has already earned my contempt. He has been given a large brain by mistake, since for him the spinal cord would suffice.

Evolution Quotes of the Day
After all, the universe required ten billion years of evolution before life was even possible; the evolution of the stars and the evolving of new chemical elements in the nuclear furnaces of the stars were indispensable prerequisites for the generation of life.
