Bibek Paudel writes "Comcast on Tuesday announced that it would partner with Pando Networks to create a P2P bill of rights for file-sharing networks and Internet service providers. Comcast and Pando will meet with industry experts, other ISPs, and P2P companies in order to come up with a set of rules that would clarify how a user can use P2P applications and how an ISP can manage file-sharing programs running on their networks. Last month, Comcast announced that it had reached an agreement with BitTorrent whereby Comcast agreed to alter its network management practices, and BitTorrent acknowledged that Comcast has the right to police its own network. Comcast's battle with P2P networks started last year after the Associated Press published an article that accused Comcast of blocking peer-to-peer services like BitTorrent. Comcast admitted to delaying P2P traffic during peak times, but denied that any file-sharing applications were being completely blocked."

Bibek Paudel writes "In a move to tap the growing market of free and open source-softwares in developing economies, Microsoft and Novell have announced they were expanding their alliance into the Chinese market. Microsoft and Novell believe big enterprises in China are willing to pay to have the US firms keep hybrid systems updated and running and for assurances that there is permission to use patented software involved. The companies are marketing 'supported Linux' in which they take a fee to maintain software systems blending the open-source programs with Microsoft products such as Vista, Office, Excel and Outlook.The longtime US computer software rivals unveiled their alliance in late 2006, saying their engineers were 'building a bridge' between Microsoft's proprietary software and Novell programs based on the Linux operating system. Sunday was the first time the firms publicly targeted a specific country with their effort."

Bibek Paudel point us to a BusinessWeek report on Google's interest in the cataloging and analyzing of people's DNA. Google has recently invested in DNA screening firms Navigenics and 23andMe, which test customers' DNA for characteristics such as ancestry and predisposition for certain diseases. The customers are then able to give the information to their doctors. This is not Google's first foray into the medical industry. "Google wants to plant an early stake in a potentially large new market around genetic data. 'We are interested in supporting companies and making investments in companies that [bolster] our mission statement, which is organizing the world's information and making it universally accessible and useful,' Google spokesman Andrew Pederson says. 'We felt it was important to get involved now, at the early stage, to better understand the information generated by this fast-moving field.'"

Bibek Paudel writes "Over the past few weeks Chinese bloggers and people on Internet forums have been reacting to events in Tibet and the protests disrupting the torch relay. The BBC and Global Voices have interesting insights on the recent happenings on the Net. A western commentator says, 'Lots of Chinese people now view the Western media, human rights groups, and Western leaders' criticisms of their country as part of the Racist Western Conspiracy to Stop China From Being Successful.' One of the most vocal appeals by the Chinese blogs, forums, and text-messages has been to boycott French goods in response to the protests that accompanied the torch relay in Paris. One response post reads, 'Who is abusing human rights? Who is bringing violence to this world?' There also are two versions of music video of the song Don't Be Too CNN, and its lyric has assumed the status of a cult catch-phrase. Sina.com has a popular page: 'Don't be too CNN, fire to the Western media.' Many analysts believe that the protests over Tibet have only served to strengthen Chinese nationalism rather than evoke sympathy for the Tibetan cause. Sina.com has a petition against the Western media which has reportedly accumulated millions of signatures. There is also Mutant Palm, a blog by an expatriate in China who has been watching and commenting on the fallout from Tibet and torch protests online."

Bibek Paudel points out a story about the latest step forward in the development of nano-scale circuits. Researchers from the University of Manchester have created some of the smallest transistors ever, measuring only one atom by 10 atoms. The transistors are made out of graphene, which has the potential to replace silicon in the never-ending hunt for smaller computer technology. From NewScientist: "There are other kinds of prototype transistors in this size range. But they usually need supercooling using liquid gas, says Novoselov. The new graphene devices work at room temperature. Such prototypes are typically made by building one atom at a time, or wiring up individual molecules. Those approaches are complex and impractical, Novoselov says. By contrast, the graphene transistors were made in the same way that silicon devices are, by etching them out of larger pieces of material. 'That's their big advantage,' he says."

Bibek Paudel brings us a BBC report on the development and testing of an new ion engine by a security firm named Qinetiq. The engine will be used in an ESA spacecraft tasked with mapping the Earth's gravitational field from orbit. Only a handful of ion drives have been used for space missions before, some of which we have discussed. Quoting: "Cryogenic pumps can be heard in the background, whistling away like tiny steam engines. Using helium gas as a coolant, they can bring down the temperature in the vacuum chamber to an incredibly chilly 20 Kelvin (-253C). The pressure, meanwhile, can drop to a millionth of an atmosphere. Ion engines ... make use of the fact that a current flowing across a magnetic field creates an electric field directed sideways to the current. This is used to accelerate a beam of ions (charged atoms) of xenon away from the spacecraft, thereby providing thrust."

bibekpaudel writes "ScienceDaily reports that a wealth of papers belonging to Charles Darwin have been published on the internet, some for the first time. Some 20,000 items and 90,000 images were posted today to http://darwin-online.org.uk/. The new site is the largest collection of Darwin's work in history, according to organizers from Cambridge University Library 'This release makes his private papers, mountains of notes, experiments, and research behind his world-changing publications available to the world for free,' said John van Wyhe, director of the project. The collection includes thousands of notes and drafts of his scientific writings, notes from the voyage of the Beagle when he began to formulate his controversial theory of evolution, and his first recorded doubts about the permanence of species."

bibekpaudel brings news that researchers from Cornell University have developed a very small silicon microresonator that vibrates at the highest frequency ever recorded for such a device: 4.51 GHz. Typical quartz-crystal oscillators, commonly used in electronics as clock signals, are about a millimeter wide and operate in the KHz - MHz range. The newly developed microresonator measures 8.5 micrometers long and 40 micrometers wide, making it ideal for use in smaller circuits and microprocessing. Quoting: "One of the advantages of silicon microresonators is that they can be integrated directly into microchips using conventional manufacturing techniques, making them cheaper to produce and easier to fabricate small. Also, multiple resonators of different frequencies could be put on the same chip, says Ville Kaajakari, an assistant professor of electrical engineering at Louisiana Tech University. In a cell phone, for example, high-frequency resonators could filter out interference from other sources of radio signals."
