counterfriction writes "This month's issue of Symmetry, a magazine jointly published by SLAC and Fermilab, is featuring an article that points out the sometimes extemporaneous and unconventional solutions physicists have come up with in (and out of) the laboratory. From the article: 'Leon Lederman ... used a pocket knife, tape, and items on anyone's grocery list to confirm that interactions involving the weak force do now show perfect mirror symmetry, or parity, as scientists had long assumed.'"

ppadala writes "AT&T is upgrading their phone lines to offer video programmes over phone line. The service, called U-verse TV will be available in parts of Southern California communities initially. Channel lineups will be similar to traditional cable and dish offerings. AT&T is insisting that, 'This offering is on par with those of its cable rivals. But AT&T claims that it offers customers more for their money, including fast channel changing, video-on-demand, three set-top boxes, a digital video recorder, a picture-in-picture feature that allows viewers to surf channels without switching channels and an interactive program guide.'"

elrond writes "The US appears to have summarily rejected draft proposals for G8 members that would have agreed to tougher measures for controlling greenhouse gas emissions. The BBC reports that leaked documents have indicated the positions of the various world powers, from the timetable-setting of Germany to the US's intractable stance. Red ink comments on the documents hint at the US's irritation: 'The US still has serious, fundamental concerns about this draft statement. The treatment of climate change runs counter to our overall position and crosses 'multiple red lines' in terms of what we simply cannot agree to ... We have tried to tread lightly but there is only so far we can go given our fundamental opposition to the German position.'"

ISRO, Indian Space Research Organisation, is planning to send a robot for its mission to moon. It is probably going to be made by students and profs of IIT-Kanpur (the Indian equivalent of MIT). The two-legged robot, fitted with sophisticated sensors and high-resolution cameras, is capable of recording information and images using laser beams. It can also detect the distance of a hindrance, enter a small crater, bring surface samples and return high resolution images to the lunar vehicle. It balances cost and sophistication; basic functionality for only $50,000.

This article discusses many of the server configuration items that can make or break an application's performance and focuses on steps you can take to optimize Apache and PHP."

Atario wrote us with a link to a New Scientist article about an innovative new way of encrypting communications. An engineer at Texas A&M may have a way to exploit the thermal properties of a wire to create a secure channel. The result could be an effectively impenetrable way of securing communications, possibly outperforming quantum cryptography keys. "In their device, both the sender Alice and the receiver Bob have an identical pair of resistors, one producing high resistance, the other low resistance. The higher the total resistance on the line, the greater the thermal noise. Both Alice and Bob randomly choose which resistor to use ... Half the time ... they will choose different [resistances], producing an intermediate level of thermal noise, and it is now that a message can be sent. If Bob turns on his high resistor, and records an intermediate level of noise, he instantly knows that Alice has chosen her low resistor, in essence sending a bit of information such as 1 or 0. Kish's cipher does this many times, sending a random series of 1s and 0s that can form the basis of an encryption key, the researchers say."

An anonymous reader writes "A startup will soon launch 'a kind of holy software grail,' according to an article at LinuxDevices. The dual-licensed technology is claimed to enable more or less normal Linux applications to run — without requiring recompilation — under Windows, Mac, or Linux, with a look and feel native to each. 'As with Java, Lina users will first install a VM specific to their platform, after which they can run binaries compiled not for their particular OS, but for the VM, which aims to hide OS-specific characteristics from the application. Lina comprises a platform-specific application that virtualizes the host PC's x86 processor... A lightly modified Linux kernel (2.6.19, for now) runs on top of the VM. Under the Linux kernel is a filesystem with standard Linux libraries modified to map resources such as library, filesystem, and system calls to analogous resources on the host platform.' Further details, including an entertaining video or two are at OpenLina.com"

An anonymous reader writes "Companies are finding that this 'Web 2.0' user participation thing sometimes isn't all its cracked up to be. The New York Times reports on the efforts of big companies to harness consumer enthusiasm for assistance with advertising. Heinz, for example, is running a campaign asking users to submit videos using their product in inventive ways. The problem, of course, is that most of the submissions are utterly terrible. The result is a headache in terms of quality control and making use of the turned in submissions. 'Heinz hopes to show more than five of them, if there are enough that convey a positive, appealing message about Heinz ketchup, he said. But advertising executives who have seen some of the entries say that Heinz may be hard pressed to find any that it is proud to run on television in September. "These are just so bad," said Linda Kaplan Thaler, chief executive of the Kaplan Thaler Group, an advertising agency in New York that is not involved with Heinz's contest. One of the most viewed Heinz videos -- seen, at last count, more than 12,800 times -- ends with a close-up of a mouth with crooked, yellowed teeth. When Ms. Kaplan Thaler saw it, she wondered, "Were his teeth the result of, maybe, too much Heinz?"'"

Parallax Blue writes "The Independent is reporting new findings that indicate a common additive called sodium benzoate, found in soft drinks such as Fanta and Pepsi Max among others, has the ability to switch off vital parts of DNA in a cell's mitochondria. From the article: 'The mitochondria consumes the oxygen to give you energy and if you damage it — as happens in a number of diseased states — then the cell starts to malfunction very seriously. And there is a whole array of diseases that are now being tied to damage to this DNA — Parkinson's and quite a lot of neuro-degenerative diseases, but above all the whole process of aging.' European Union MPs are now calling for an urgent investigation in the wake of these alarming new findings."
