Theorists Make Quantum Communications Breakthrough 155

KentuckyFC writes "One of the cornerstones of modern physics is Claude Shannon's theory of communication, which he published in 1948. If you've ever made a phone call, watched TV, or used a computer, you've got Shannon to thank for describing how information can be moved from one place in the universe to another using an idea called the channel capacity. But nobody has been able to develop a quantum version of this theory. So physicists have no idea how much quantum information can be sent from one point to another. Now two American physicists have made an important breakthrough by proving that two quantum channels with zero capacity can carry information when used together. That's interesting because it indicates that physicists may have been barking up the wrong tree with this problem: it implies that the quantum capacity of a channel does not uniquely specify its ability for transmitting quantum information (abstract). And that could be the idea that breaks the logjam in this area."

Why Google Should Embrace OpenOffice.org 277

CWmike writes "Preston Gralla has a decent idea that could move the office needle: If Google really wanted to deliver a knockout punch to Microsoft, it would integrate OpenOffice with Google Docs, and sell support for the combined suite to small businesses, medium-sized business, and large corporations. Given the reach of Google, the quality of OpenOffice, and the lure of free, it's a sure winner. Imagine if a version of it were available as a Web service from Google, combined with massive amounts of Google storage. Integrated with Google Docs, it would also allow online collaboration. For those who wanted more features, the full OpenOffice suite would be available as a client — supported by Google. wouldn't be at all surprised to see this happen. Just yesterday, IBM announced that it was selling support for its free Symphony office suite. It's not too much of a stretch to imagine Google doing the same for OpenOffice, after it integrates it with Google Docs."

Silent Microchip 'Fan' Has No Moving Parts 136

from the cool-off dept.
Stony Stevenson writes "Researchers in the US have developed a microchip fan with no moving parts that operates silently and generates enough wind to cool a laptop computer. The solid-state fan, developed with support from the US National Science Foundation (NSF), is touted as the most powerful and energy efficient fan of its size. The device produces three times the flow rate of a typical small mechanical fan and is one-fourth the size. The technology has the power to cool a 25W chip with a device smaller than one cubic-cm and can someday be integrated into silicon to make self-cooling chips, according to the researchers."

Endeavour Crew to Assemble Giant Robot, in Space 147

Frizzled writes "Part of the space shuttle crew's scheduled mission for this week is to assemble a massive robot which will 'rise like Frankenstein' from the shuttle's cargo bay. The robot, named Dextre, has 11-foot arms, a shoulder span of nearly 8 feet, a height of 12 feet, and was built by the Canadian Space Agency. 'Dextre can pivot at the waist, and has seven joints per arm. Its hands, or grippers, have built-in socket wrenches, cameras and lights. Only one arm is designed to move at a time to keep the robot stable and avoid a two-arm collision. The robot has no face or legs, and with its long arms certainly doesn't look human.'"

Kimchi in Space 270

rtknox00 writes "For astronauts spending months in space, the smallest touch of home can make a big difference. So when South Korea's first astronaut Ko San boards the International Space Station this April he'll be bringing along a hefty supply of kimchi, the national dish of his native country. While bringing a cherished food on a long journey might seem like a simple act, taking kimchi into space required millions of dollars in research and years of work." Science may never get Thorramatur in orbit.

FBI Accidentally Received Unauthorized E-Mail Access 122

AmishElvis writes "The New York Times reports that 'glitch' gave the F.B.I. access to the e-mail messages from an entire computer network. A hundred or more accounts may have been accessed, rather than 'the lone e-mail address' that was approved by a secret intelligence court as part of a national security investigation. The episode was disclosed as part of a new batch of internal documents that the F.B.I. turned over to the Electronic Frontier Foundation, as part of a Freedom of Information Act lawsuit the group has brought."

Negroponte vs Intel 283

from the in-this-corner dept.
Yogi_Stewart_4 writes "More OLPC/Intel love — apparently Intel used 'underhanded' tactics to try to block sales' contracts of the OLPC, trying to reach the customer directly after an agreement had been reached. "They would go in even after we had signed contracts and try to persuade government officials to scrap their contract and sign a contract with them instead. That's not a partnership." Mr Negroponte cited an example in Peru where Intel sales staff tried to persuade the country's vice-minister of education, Oscar Becerra Tresierra, to buy the Intel Classmate PC."

+ - Google's Shadow Over Firefox->

eldavojohn writes "Mozilla's chief executive now earns roughly half a million in pay and benefits. But where did the $70 million in assets that they had in 2006 come from? Well, 85 percent of their $66 million in revenue for 2006 came from Google. While it's clear that the community's code is what makes Firefox successful, people are worried that Mozilla is becoming dependent on this cash and — even worse — that Firefox is just a pawn in Google's cold war with Microsoft."
