Feed Science Daily: New Insights Into Cardiac Aging (sciencedaily.com)

Researchers have found that the conserved protein d4eBP modulates cardiac aging in Drosophila (fruit flies). The team also found that d4eBP, which binds to the protein dEif4e, protects heart function against aging.

Submission + - Security/Privacy Advice

James-NSC writes: My employer is changing its policy towards employee use of social networks. I've been asked to give a 40 minute presentation to the entire company (attendance is mandatory) on the security and privacy concerns pertaining to social networking. While I was putting it together, I ended up with some miscellaneous information that pertains to security/privacy in general. Ex: the emerging ATM skimming (mainly for our European employees), a reminder that email is not private, malware/drive-by in popular search results, things of that nature. Since these don't really fall into the slated topic, I've ended up with a section titled "While I have you...". I'm going to have the attention of every employee and with attendance being mandatory, I thought it would be a great opportunity to give advice on security/privacy issues as a whole and not just those pertaining to social networks. As it's an opportunity that one seldom gets, I'd hate to not utilize it to its full potential. If you had the attention of an entire company with employees in the US, UK, Asia and Australia, what advice would you give?

Submission + - Planck Satellite Releases First Images (wordpress.com)

davecl writes: The Planck Satellite has released its first images. These are from the 'First Look Survey' and show a strip of the sky scanned at a range of radio and submillimetre wavelengths. The results are already better than what was seen by the previous microwave background satellite, WMAP. ESA's coverage of the results can be found here, with more details and images available in English and French. The Planck Mission Blog contains more details of the project and continuing coverage. I maintain the mission blog but even I am impressed with these first images!

Submission + - Old operating systems don't die... (technologizer.com)

Harry writes: "Haiku, an open-source recreation of legendary 1990s operating system BeOS, was released in alpha form this week. The news made me happy and led me to check in on the status of other once-prominent OSes--CP/M, OS/2, OS/2, AmigaOS, and more. Remarkably, none of them are truly defunct: In one form or another, they or their descendants are still available, being used by real people to accomplish useful tasks. Has there ever been a major OS that simply went away, period?"

Submission + - Is Happiness Catching? (nytimes.com)

chrb writes: The New York Times has an interesting article about research into modelling of real world social networks, and how tendencies to be happy, to smoke, and to become obese, are passed between nodes in a directed graph in a way that suggests such concepts are "contagious". Well connected nodes in the graph (i.e. people with more friends) are more likely to be happier than less connected nodes, even when the edges represent more distant friendships. Individuals quitting smoking, or becoming obese, influence not only their immediately connected friends, but also friends of friends, with the effect sometimes skipping the intermediary node. The contagion effect is most noticable when a tendency is passed from one person to another of the same sex — friends of the opposite sex, including spouses, are not as influential.

Time Warner Cable Implements Packet Shaping 492

RFC writes "In a move that may be indicative of modern ISP customer service, Time Warner has announced the introduction of packet shaping technology to its network. 'Packet shaping technology has been implemented for newsgroup applications, regardless of the provider, and all peer-to-peer networks and certain other high bandwidth applications not necessarily limited to audio, video, and voice over IP telephony.' As the poster observes, this essentially renders premium service useless. The company is already warning users that attempts to circumvent these measures is a violation of their Terms of Service."

Microsoft's IIS is Twice as Likely to Host Malware? 163

eldavojohn writes "According to Google, Microsoft's server software is at least twice as likely to host viruses or malware. The reason why? 'Google reports that IIS is likely used to distribute malware more often than Apache because many IIS installs are on pirated Windows versions which aren't configured to automatically download patches. (Even pirated Windows versions can automatically receive security fixes, however.) Our analysis demonstrates how important it is to keep web servers patched to the latest patch level,' Google notes."

Long Block Data Standard Finalized 199

An anonymous reader writes "IDEMA has finally released the LBD (Long Block Data) standard. This standard, in work since 2000, increases the length of the data blocks of each sector from 512 bytes to 4,096 bytes. This is an update that has been requested for some time by the hard-drive industry and the development of new drives will start immediately. The new standard offers many advantages — improved reliability and higher transfer rates are the two most obvious. While some manufacturers say the reliability may increase as much as tenfold, the degree of performance improvement to be expected is a bit more elusive. Overall improvements include shorter time to format and more efficient data transfers due to smaller overhead per block during read and write operations."

Deep Impact Mission May Be Extended 50

SeaDour writes "The famous Deep Impact mission, which in 2005 launched a projectile in the path of comet Tempel 1, may be extended by NASA. The proposal is to slingshot the probe around the Earth as it passes by at the end of this year, putting it on a trajectory to reach comet Boethin in December 2008. Scientists want to see if the strange composition and behavior of Tempel 1 is more common than they had previously assumed. (The probe only had one projectile though, so we will not see another brilliant man-made explosion on this comet.) Additionally, while the probe is en route to the comet, researchers will point its on-board telescope at known exosolar planets to determine the compositions of their atmospheres."

Samsung to Launch Dual Blu-ray HD DVD Player 156

narramissic writes "File this one under 'if you can't beat em, join em.' Samsung, one of the main backers of the Blu-ray Disc format, Friday said it plans to release an optical disc player this year that will play both Blu-ray Disc and the rival HD DVD format. With the announcement, Samsung becomes the second company to shift from a single-format stance (LG launched a dual player in North America earlier this year.) 'Our main concern is with the consumer and not a particular technology,' said Samsung spokesman Kwak Bumjoon."

Scientists Map DNA of Rhesus Monkeys 104

KingKong writes "Scientists have unraveled the DNA of another of our primate relatives, this time a monkey named the rhesus macaque — and the work has far more immediate impact than just to study evolution. These fuzzy animals are key to testing the safety of many medicines, and understanding such diseases as AIDS, and the new research will help scientists finally be sure when they're a good stand-in for humans. 'Having a third primate will allow scientists to compare the three genomes, with an added emphasis on singling out the genes possessed by humans alone. The end goal is to reconstruct the history of every single one of the approximately 20,000 genes, to determine when they first appeared in history, and in what species. All of this requires an extraordinary amount of information.'"

Building Brainlike Computers 251

newtronic clues us to an article in IEEE Spectrum by Jeff Hawkins (founder of Palm Computing), titled Why can't a computer be more like a brain? Hawkins brings us up to date with his latest endeavor, Numenta. He covers progress since his book On Intelligence and gives details on Hierarchical Temporal Memory (HTM), which is a platform for simulating neocortical activity. Programming HTMs is different — you essentially feed them sensory data. Numenta has created a framework and tools, free in a "research release," that allow anyone to build and program HTMs.

Getting High-Quality Audio From a PC 295

audiophile writes "Just because it's a PC doesn't mean it can't output good-sounding audio. In the same vein as specialty A/V products, you can find PC-based A/V systems with extensive audio processing and step-up performance specifications, including Signal-to-Noise ratio, which can make a significant difference when using the analog outputs. Media center manufacturer Niveus shares tips for getting high-quality audio from a PC."

Intel Reveals the Future of the CPU-GPU War 231

Arun Demeure writes "Beyond3D has once again obtained new information on Intel's plans to compete against NVIDIA and AMD's graphics processors, in what the Chief Architect of the project presents as a 'battle for control of the computing platform.' He describes a new computing architecture based on the many-core paradigm with super-wide execution units, and the reasoning behind some of the design choices. Looks like computer scientists and software programmers everywhere will have to adapt to these new concepts, as there will be no silver bullet to achieve high efficiency on new and exotic architectures."
