Sun Turns to Lasers to Speed Up Computer Chips 130

alphadogg writes to mention that Sun is attempting to move from the typical design of multiple small chips back to a unified single-wafer design. "The company is announcing today a $44 million contract from the Pentagon to explore replacing the wires between computer chips with laser beams. The technology, part of a field of computer science known as silicon photonics, would eradicate the most daunting bottleneck facing today's supercomputer designers: moving information rapidly to solve problems that require hundreds or thousands of processors."

Lakes Found Under Antarctic Ice Using Space Lasers 77

Reverse Gear writes "There is a new study circling the media about new lakes found underneath the antarctic ice sheets that apparently empty and fill back up quite fast. 'The scientists allay fears that global warming has created these pockets of water. They say these lakes lie some 2,300 feet below compressed snow and ice, too deep for environmental temperature to reach. However, it is necessary to understand what causes the phenomenon as it can facilitate an understanding of the impact of climate change on the ice sheet in Antarctica.' NASA also has some information on the technique used to detect these lakes."

Open Source Laser Business Opens In New York 96

ptorrone writes "If you can't stand the idea of a cookie-cutter laptop and you live in New York City, you have a new option: laser-etching. Phil Torrone, an editor at Make magazine, and Limor Fried, a former fellow at the tech-focused art studio Eyebeam R&D, are working together on Adafruit Laser Services, a new, by-appointment-only business in Manhattan that etches custom artwork onto customers' laptops, iPods, cell phones, and other gadgets." The entire business will be open source. From the Adafruit Laser Services site: "We are publishing how to use the high powered laser system, set up, techniques, business practices and templates. You could start your own laser business, we'll even help you."

Chinese Lasers Blind US Satelites 739

SniperClops writes, "China has fired high-power lasers at U.S. spy satellites flying over its territory in what experts see as a test of Chinese ability to blind the spacecraft, according to sources." The article mentions the reluctance of the U.S. administration to talk about this "asymmetric" effort by the Chinese military.
