New Breathalyzer Technology Detects Cancer, Asthma

(NaturalNews) Researchers are working to develop ways to test for various diseases simply by having patients breathe into a machine, according to an article published in the online edition of Optics Express. "If you go to the medical literature you will see tons of studies that correlate certain diseases with particular molecules found in the breath," said researcher Jun Ye. "One common example is nitrous oxide, which is associated with asthma." Ye and colleagues have successfully created a device that can analyze the millions of molecules contained in a single human breath. They believe the machine can easily be adapted to detect for a variety of lung-diseases as well. "It's very non-invasive," Ye said. "There's nothing to be scared of. No blood test, just a breath test." The machine is analyzes the content of a breath by bouncing lasers back and forth between two curved mirrors. These lasers excite the air, causing each molecule to give off a unique light signature. These signatures are then analyzed to determine the chemical composition of the air. This composition can provide important medical clues. In preliminary tests, for example, the breath of a smoker was found to contain five times the carbon monoxide concentration of other participants. "If you have asthma, your breath will have nitrous oxide, but nitrous oxide does not necessarily mean you have asthma," said Ye. "But if you see several different molecules all at once, and they are associated with asthma, then you have found a real fingerprint of a certain disease." Ye and his colleagues are working to make the machine even more sensitive, in the hopes that it can one day be used to identify even diseases that do not involve the lungs. "Once it's mass produced, the cost could be quite low," Ye said. "It could be put into every doctor's clinic so people could walk in and do painless breath tests and then walk away. They would get results in a day or so."

Intel Xeon® 'Nehalem-EX' Processor Presented by Intel

A new Intel® Xeon® processor codenamed "Nehalem-EX" has been revealed by Intel. Being able to deliver a number of new technical advancements and boost enterprise computing performance, the processor will be running the next generation of intelligent and expandable high-end Intel server platforms.

The Nehalem-EX processor, being ready to enter production later this year, will feature up to eight cores inside a single chip supporting 16 threads and 24MB of cache. Offering the highest-ever jump from a previous generation processor, its performance increase will be dramatic.

New reliability, availability and serviceability (RAS) features usually found in the company's Intel® Itanium processor family, such as Machine Check Architecture (MCA) Recovery will be available with Nehalem-EX.

the new Nehalem-EX processor, being ideal for virtualized applications, server consolidation, data demanding enterprise applications and technical computing environments, will be able to boost up to nine times the memory bandwidth of the previous-generation Intel Xeon 7400 platform, also doubling the memory capacity with up to 16 memory slots per processor socket, and offering four high-bandwidth QuickPath Interconnect links. Without the need for third-party chips to "glue" the platform together, Nehalem-EX will provide tremendous scalability, from large-memory two-socket systems through eight-socket systems capable of processing 128 threads simultaneously, while, with third-party solutions, additional scalability options including greater sockets counts will also be possible.

Some of the main advantages of Nehalem-EX are:

* Intel Nehalem Architecture built on Intel's unique 45nm high-k metal gate technology process
* Up to 8 cores per processor
* Up to 16 threads per processor with Intel® Hyper-threading

* Intel scalable memory buffer and scalable memory interconnects
* Support for up to 16 memory slots per processor socket
* Up to 9x the memory bandwidth of previous generation
* 2.3 billion transistors
* Advanced RAS capabilities including MCA Recovery

Nehalem-EX, having new RAS capabilities for high-end enterprises, will be able to accelerate IT adoption of Intel-based platforms over RISC-based platforms by delivering a lower total cost of ownership, higher performance, lower electricity bills and the ability to standardize on a flexible IT environment.

LED light bulbs yield big savings in energy

One way the United States could slash its electricity use, dependence on fossil fuels and emissions of heat-trapping gases is really quite simple: better light bulbs.

The Department of Energy is backing research and development aimed at getting light-emitting diodes into common use in homes and businesses at a price that saves money. Hurdles remain: Costs are still high, the quality of what's on the market varies and not all the technical issues have been worked out. Energy experts are confident, however, that this new lighting is the future and that energy savings will be enormous.

Lighting consumes 22 percent of electricity in the United States. The DOE predicts that solid-state lighting -- which uses semiconducting materials to convert electricity into light, and includes LEDs -- has the potential to reduce energy use for lighting by one-third by 2030. That's the equivalent of saving the output of 40 large (1,000-megawatt) power plants, the greenhouse gas emissions of 47 million cars and $30 billion.

LEDs already light universities from Miami to Anchorage, Alaska, streets in many cities and an increasing number of businesses that need lights on all the time.

"In your home, lighting may be 10 percent of your bill. But in an office building it's probably 40 percent, and so if you reduce your lighting energy consumption by a large fraction, the savings will be huge," said James Brodrick, who leads the DOE's solid-state lighting program.

A fact sheet from Brodrick's office says this about LEDs: "In the coming decade, they will become a key to affordable net-zero energy buildings, buildings that produce at least as much energy annually as they use from the grid."

The technology is advancing quickly, and costs will continue to drop, Brodrick said. The DOE tests LEDs and sets performance and efficiency guidelines under its Energy Star program.

LEDs are directional lights, used in recessed lighting and under-counter lights, for example. They're not yet available as bulbs that cast light all around and fit in ordinary sockets.

"There's an enormous and exciting potential, but we have a long way to go before we see anything besides directional lighting," said Jeffrey P. Harris, the vice president for programs at the Alliance to Save Energy, a nonprofit group that promotes energy efficiency.

Even so, LEDs already are used to light offices, hotels, restaurants and other businesses.

The DOE predicts that LEDs will have better performance capability than fluorescent lighting in the next few years, and that they'll continue to improve after that. They're now comparable with fluorescent fixtures in efficiency, and the DOE says its Energy Star LEDs last two to five times longer.

Cost is the biggest reason that LEDs aren't used more widely, Brodrick said.

A common PAR 38 floodlight at Home Depot, for example, costs about $35 online as an LED, about $3.70 apiece in a pack of 15 as a halogen floodlight and about $11 for a compact fluorescent.

Chuck Swoboda, the chairman and chief executive officer of Cree Inc. of Durham, N.C., a leading company in LED lighting, said that commercial use of LEDs would drive down costs, and that a lower initial cost plus the value of energy savings would make them attractive. "It's not that different from the argument of why you should put insulation in a home," he said.

LEDs have other advantages: They can be dimmed, don't emit heat, don't contain mercury -- unlike compact fluorescents -- and can produce warm-toned light.

Swoboda said that Cree was focusing on commercial sales now because that market was bigger than the residential market and commercial users got quicker paybacks from reduced energy and maintenance costs.

In April, Cree announced that it had a new LED PAR 38 bulb designed for stores and museums that uses 12 watts of power instead of 50 to 90 watts for a halogen bulb.

"What happens with LEDs is people think of them as things that go in your cell phone or things you put in the car dashboard, but they don't think of it as truly a lighting product," Swoboda said. "And so this was the latest innovation to kind of go out and show people you can pretty much do anything you can do in an incandescent bulb technology or in fluorescents with LEDs."

Home Depot, the world's biggest retailer of light bulbs, is starting to stock LED bulbs this summer and plans to have 10 kinds by September, said Jorge Fernandez, who's in charge of light bulb purchases for the company.

"There's definitely a lot of interest, but the price is high, and a lot of people say they're waiting to see when the price drops," he said.

Felicia Spagnoli, a spokeswoman for Philips Lighting Electronics North America, said commercial users could make up for the higher costs of LEDs in as little as a year or two.

"We can address environmental concerns at the same time we improve the quality and use of light," she said. "Many people when they think of doing good for the environment think it means going without or having lesser quality, but that's absolutely not the case with LEDs."

Philips is working on many kinds of LEDs, including one to replace a 40-watt incandescent bulb that's scheduled to be available next year, she said.

Derrick Hall of RE/Construct Inc. in Asheville, N.C., said that residential customers weren't asking for LEDs because of the high upfront cost. Still, he's hearing of some nonresidential customers who are looking into LEDs for the energy savings.

LEDs are much better than other lighting options, Hall said. The quality of the light is "far superior," they offer big energy savings and there's no cost to society for dealing with mercury, he said. Mercury, a neurotoxin, is found in small amounts in compact fluorescent bulbs.

Swoboda said that some of the biggest commercial users for LEDs now were fast-food restaurants, because LEDs' light makes food look appealing.

A McDonald's that opened in July in Cary, N.C., is lit almost entirely with daylight and LED lights. Ric Richards, the franchise owner, said the restaurant used 78 percent less electricity than a traditional one.

And the quality of the light?

"Awesome," he said. "The restaurant has great ambience."

Richards estimated that the upfront costs of the lighting would be paid back in two to four years with lower electricity bills.

In Washington, the Pentagon is installing LED lights in a large renovation.

Mark Buffler, an official in charge of technology in the Office of the Secretary of Defense, said in a report that switching from conventional fluorescents to LEDs would conserve large amounts of energy _ 240,000 kilowatt hours annually _ and save money on maintenance and mercury disposal. Buffler also wrote that the project was meant to demonstrate the energy savings potential of LEDs for the rest of the federal government.

Online MS Office 2010: for free or not?

It was last week when Microsoft announced that they will offer a "Free" lightweight online version of Microsoft 2010, which includes Word, Excel, Powerpoint and OneNote. Since then, I started to read reviews and press releases of this move from Microsoft and started to draft a post regarding this big change that the company does. But what made me changed my mind to post that said draft is because of Michael Hickins's report on the Hidden cost of Microsoft's Free online office suite.

Just a quote from his post, "But wait – there’s more! A Microsoft spokesperson told me that customers will need to buy a SharePoint server, which ranges from $4,400 plus CALs or $41,000, all CALs included if they want to share documents using the online version of Office 2010"
I bet its really clear that there is always a hidden agenda on that Free offerings. And as usual, at the end of the day, business is business.

At first, i enjoyed comparing these two online applications; namely Microsoft office live workspace and Google Docs, but at the end i would prefer to use Google docs than any other, most especially when i used it to convert office 2007 files into 2003. The two web versions of applications, have offer lots of advantages, doing some documents online anytime and anywhere but do Microsoft risks its sells of Office Applications (as we know, Office is the company's big cash drawer) and goes with online versions?

Office 210: The Changes

And now, as what i am always looking forward, is the idea and inquiry what could be the changes that Microsoft can offer rather than the online version thingy?


[2007 VS 2010: Ribbon Changes]

First of all, is the revision of the Microsoft Office 2007 trade mark, the Ribbon. In the offline version, Microsoft designed the Ribbon enclosed with a circular form on which at first i thought it was just another nonfunctional design until such time i learned that it is somewhat like a functional button having there the sub menus; New, Open, Save and others.
Another offering is the photo editing tools, which can now be accessed inside the Ribbon. You just need to open a picture file, then a format tab will show and you can now do some photo enhancement.


[Office 2007: Sub Menus under the Ribbon ]

And another ribbon inclusion program (which is excluded last 2007 version) is the Outlook 2010. It do now have full marked ribbon and is offering the same overall interface except its new feature Quick Steps. Excel and Word have no lots of new features on them not like outlook and of course the PowerPoint which give a video features in it.



Just a note, to access the lightweight version of office 2010, you all need a Windows Live ID (formerly hotmail account). But not so sure if you can have a total access on that package since Microsoft has not released any news about it although they have appended the word "free".

Cyber Attack Code Starts Killing Infected PCs

By Thomas Claburn

Read the Original Article at InformationWeek

Infected computers participating in the distributed denial of service attack on U.S. government and South Korean Web sites are set to destroy their own data.

The botnet-driven cyber attack on government, financial, and media sites in the U.S and South Korea includes a newly discovered danger: The malicious code responsible for driving the distributed denial of service attack, known as W32.Dozer, is designed to delete data on infected computers and to prevent the computers from being rebooted.

"Your machine is completely hosed at this stage," said Vincent Weafer, VP at Symantec Security Response.

The malicious code includes instructions to start deleting files when the infected computer's internal clock reaches July 10, 2009. That's today.

According to Weafer, the malicious code will attempt to locate files with any of more than 30 different extensions, such as .doc, .pdf, and .xls, copy the data to an encrypted file that's inaccessible to the user, and then overwrite the data in the original files. It targets files associated with office, business, and development applications.

The malicious code is also programmed to modify infected computers' Master Boot Records. The change renders computers inoperable following any attempt to reboot.

The impact of this self-destruct sequence should be minimal, however. Weafer said that he expects only a few thousand machines will be damaged. "I don't expect this to be a major issue, except perhaps in South Korea," he said.

The cyber attack against sites in the U.S. and South Korea began on July 4 and temporarily interfered with access to the Web sites of the Treasury Department, the Transportation Department and the Federal Trade Commission.

The South Korean Intelligence Service estimated that about 20,000 compromised computers -- mostly in South Korea -- had been ordered to conduct a Distributed Denial of Service (DDoS) attack on U.S. and South Korean sites.

Given the timing, which coincided with a North Korean missile test, suspicions have been raised about the involvement of hackers in North Korea or possibly China.

In a press briefing yesterday, State Department spokesman Ian Kelly said, "[The attacks] are continuing, and we are taking measures to deal with this and any potential new attacks." He said he had no information about whether North Korea was involved.

It is possible to direct an attack of this sort from anywhere. According to Alan Paller, research director at The SANS Institute, the compromised computers participating in this attack are located all over the world, including the U.S. The bots that participate also vary over time, so that the source of the attack is constantly changing.

"The attacks have become increasingly sophisticated since the end of last week -- it started as a flood that was easy for network service providers to filter and then went through at least two increases in sophistication so that the flood looks more and more like legitimate traffic," said Paller in an e-mail. "Network providers have to work much harder to filter out malicious traffic that resembles legitimate traffic."

But with W32.Dozer already deleting files and crippling its hosts, the attacks should soon subside.
