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."

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."

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.
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."
