Submission + - SPAM: Second Earth Found? Location Is Promising

ourscompany writes: "NASA announced a major milestone in the quest for life in the universe Monday: The discovery of another planet close enough to the sun it orbits to potentially support life.
Called Kepler-22b, the planet is about 2.4 times the radius of Earth and about 600 light-years away. And it orbits in the “habitable zone,” the region of space just far enough from a star that liquid water could exist on the planet’s surface — a discovery could have profound implications in the quest for alien life, said Alan Boss, an astrophysicist with Carnegie Melon University."

1Gbps Optical Wireless Network Might Replace Wi-Fi 200

Mark.JUK writes "Pennsylvania State University has developed a new method of indoor Optical Wireless network that does not require a line-of-sight and runs at speeds of 1Gbps+. The system uses a high-powered laser diode — a device that converts electricity into light — as the optical transmitter and an avalanche photo diode — a device that converts light to electricity — as the receiver. The light bounces off the walls and is picked up by the receiver. Traditional radio frequency systems (Wi-Fi , WiMAX etc.) do not require line of sight transmission, but can pass through some substances and so present a security problem. Light, in a room without windows, will not escape the room, improving security."

Submission + - Bringing Free Television to Phones in America (economist.com)

ideonexus writes: South Korea, China, Brazil, parts of Europe, and Japan have been watching television on their phones for free since 2005, but American mobile carriers are struggling to offer clunky streaming video using Qualcomm’s proprietary MediaFLO system for an additional monthly fee and excessive bandwidth demands. Now, with America having gone digital in June, if Mobile carriers were to have ATSC M/H (advanced television systems committee—mobile/handheld) television-tuner chips built into their handsets it sounds like we could enjoy free TV on our cell phones too; however, these companies have already invested a great deal of money adapting their networks to Qualcomm's format and Qualcomm is considering becoming a Mobile-television distributor itself.

Google Envisions 10 Million Servers 169

miller60 writes "Google never says how many servers are running in its data centers. But a recent presentation by a Google engineer shows that the company is preparing to manage as many as 10 million servers in the future. At this month's ACM conference on large-scale computing, Google's Jeff Dean said he's working on a storage and computation system called Spanner, which will automatically allocate resources across data centers, and be designed for a scale of 1 million to 10 million machines. One goal: to dynamically shift workloads to capture cheaper bandwidth and power. Dean's presentation (PDF) is online."
