The results page gives users the option to narrow down or filter to produce desired results. For example, I searched for migraine and it let me choose from various options including: treatment, research papers, symptoms, news and alternative medicine. Clicking on "From medical establishment" gives even more options.

Basically, Google Health is what I expected -- an enhanced way to search for health related material. Lots of people were hoping for a more feature-rich product (including myself) but that's not usually how Google operates. They like to see and hear what people want before they spend time developing what they think people want -- this is how they get things done so quickly.

In a private meeting with industry representatives, Gonzales, Mueller and other senior members of the Justice Department said Internet service providers should retain subscriber information and network data for two years, according to two sources familiar with the discussion who spoke on condition of anonymity.

The closed-door meeting at the Justice Department, which Gonzales had requested, according to the sources, comes as the idea of legally mandated data retention has become popular on Capitol Hill and inside the Bush administration. Supporters of the idea say it will help prosecutions of child pornography because in many cases, logs are deleted during the routine course of business.

Privacy advocates have been alarmed by the idea of legally mandated data retention, saying that, while child exploitation may be the justification today, those records would be available in all kinds of criminal and civil suits--including terrorism, tax evasion, drug, and even divorce cases.

It was not immediately clear what Gonzales and Mueller meant by suggesting that network data be retained. One possibility is requiring Internet providers to record the Internet addresses their customers are temporarily assigned. A more extensive mandate would require companies to keep track of e-mail messages sent, Web pages visited and perhaps even instant-messaging correspondents.

The company will require that all of its cafes and cafeterias serve only the pricier cage-free eggs, the San Jose Mercury News reports. Google uses about 300,000 eggs a year along with 7,000 pounds of liquid egg products.

Animal-rights activists charge that caged chickens -- sometimes called battery-raised, because the cages are piled high -- have miserable lives during their productive egg-laying months, confined six to a cage with only 67 square inches of floor space per chicken. Egg farmers say caged chickens are just as happy as -- and healthier than -- those raised outdoors or in open barns.

Google is jumping on a bandwagon that already includes America On Line and Bon Appetit Management, a catering company serving a number of Silicon Valley companies. Several universities have also pledged to serve cage-free eggs.

IRobot Inc. Chief Executive Colin Angle said one group of soldiers even named its robot "Scooby Doo" and grieved when it was blown up after completing 35 successful missions defusing improvised explosive devices.

"Please fix Scooby Doo because he saved my life," a soldier told repair technicians, according to Angle's account at last week's Future in Review technology conference.

The company, which is best known for "Roomba," the robotic vacuum cleaner, and "Scooba," the floor-mopping robot, envisions a machine that would instill similar feelings in civilians.

Angle did not hesitate when asked if he thinks the bond soldiers have formed with his robots is normal.

"I think it's very rational," he said. "(Scooby Doo) was someone, something, that was doing a great service for them and thus when they brought it back, it was viewed not just as a loss of a machine gun or a piece of body armor or a helmet. It was a loss of a contributing member of the team."

Under the idea, which Microsoft is introducing this week, people would be able to get a PC for their home with a mechanism that charges them depending on how much computing they use. Consumers would pay for about half of the PC upfront and then, say, 50 cents or 75 cents per hour of use. After several hundred hours of paid use, they would then own the PC outright.

"The real goal of FlexGo is to make that dream of owning a full-featured PC a reality," said Mike Wickstrand, director of product management in the market expansion group at Microsoft.

The exact finances of the program would vary, depending on a number of factors. These include the cost of the software and hardware being used, as well as the country's prevailing lending interest rate. Microsoft has already tested the idea in Brazil, but plans to expand that program in coming weeks, alongside new trials in Russia, India, China and Mexico.

Microsoft has been grappling with the challenges of emerging markets for some time. The company has offered a lower-priced operating system option, its stripped-down Windows XP Starter Edition, as part of low-cost PC programs across the globe. But total shipments of Starter have been modest, with the company having sold 100,000 copies as of last July.

Blue Security, which debuted its spam-fighting service last summerand built up a user base of more than 500,000, decided to wave the white flag after its servers were knocked offline by an aggressive denial-of-service (DoS) attack it claimed was launched by a deep-pocket Russian spammer tagged as "PharmaMaster."

May 3, in an attempt to get out the word about the DoS, Blue Security repointed its domain to an unused blog on Six Apart's TypePad blogging service. Within minutes, PharmaMaster attacked the blog with another DoS, which brought down Six Apart and left millions without access to their blogs. Blue Security's domain name service provider, Tucows, was also hit with a DoS and knocked offline for several hours; Tucows going down took thousands of Web sites it hosts with it.

Wednesday, Blue Security said it had to give up because it couldn't sustain the fight against spammers. "Several leading spammers viewed [us] as a strategic threat to their spam business," Eran Reshef, Blue Security chief executive wrote in the message posted to the company's site.

"After recovering from the attack, we determined that once we reactivated the Blue Community, spammers would resume their attacks. We cannot take the responsibility for an ever-escalating cyber war through our continued operations.

Microsoft's next chapter in its battle against the iPod and ITunes begins this week, as the company releases Windows Media Player 11 to the public. Additionally, Microsoft will promote heavily a test version of the URGE music service, a project it co-developed with MTV.

Seeing that a seamless ecosystem is what has propelled the iPod to its iconic status, Microsoft has also taken a page from the Apple playbook and co-developed a portable player called the "Clix." The new device is a project between Windows-based player market leader iRiver and the Redmond company.

The deluge of media-related announcements is seen by some as an indirect admission that the company's previous strategy of allowing freedom among its partners to do as they wish in the digital media space was a failure.

Companies like Creative have struggled to succeed in a crowded market where more than a half dozen major players plus dozens of smaller outfits compete for less than a fifth of the market. The result has been a disaster not only for most of these companies financially, but for Microsoft in the minds of the consumer.

Hursti's findings suggest the possibililty of other attacks, not described in his report, that are even more worrisome.

In addition, compromised machines would be very difficult to detect or to repair. The normal procedure for installing software updates on the machines could not be trusted, because malicious code could cause that procedure to report success, without actually installing any updates. A technician who tried to update the machine's software would be misled into thinking the update had been installed, when it actually had not.

On election day, malicious software could refuse to function, or it could silently miscount votes.

Google already has Google Earth, a 3-D mockup of the planet generated from satellite photos. But Google wants you to do more than just zoom through its virtual Earth. The company wants you to add on to it, too.

At the end of April the company released, for free, a popular 3-D modeling program it bought called SketchUp. Google is encouraging developers to use SketchUp to build 3-D layers on top of Google Earth. There's even a website Google provides called 3-D Warehouse, where you can demonstrate what you've built in Sketch Up.

The notion that you can create objects and buildings and place them in a virtual world makes Google Earth sounds less like a mapping tool and more like a metaverse. What's a metaverse? Science fiction writer Neal Stephenson introduced the term in his seminal 1992 novel, Snow Crash. The metaverse was Stephenson's name for a virtual world where his characters play and do business. It was a black ball 1.6 times the size of Earth, with a giant street running around its equator.

"It's a long-term investment, like owning a home," says Lawrence Fischer, vice president of business development at SmartName.com, a company that owns and manages thousands of domain names, including Stockquotes.com. "But if a major brokerage firm came along with a big offer, I would be willing to listen."

Plenty have been willing to pay. Sales of 5,851 domain names generated $29 million in 2005, compared with the sale of 3,813 names for $15 million in 2004, market researcher Zetetic says.

Venture-capital firms, too, are betting on domains. Last year, Highland Capital Partners plunked down more than $20 million on YesDirect, a holding company with 600,000 domain names. YesDirect is developing content for websites using the names, says Bob Davis, a managing general partner at Highland.

Further underscoring the hot domain-name market: Its biggest trade show ever took place in Las Vegas last week. About 400 to 500 domainers and investors took part -- double what the same show drew a year ago, organizer Rick Schwartz says. Officials at Yahoo and Google, both of which own domain names, attended. There, the largest live domain-name auction produced $2.1 million in sales in three hours.

In launching comScore World Metrix, the company announced that 694 million people, age 15+, used the Internet worldwide from all locations in March 2006, representing 14 percent of the world?s total population within this age group. This number marks the first worldwide universe estimate based on a consistent methodology across all countries.

Notably, comScore World Metrix includes measurement of the major Asian countries, including China, Japan, India and Korea, which represent nearly 25 percent of the total worldwide online population (or 168.1 million users), and which, in the aggregate, are 11 percent larger than the U.S. (152 million users).

Minka Wiltz, an actress in Atlanta, has tried to answer her phone to the thrrrrup, thrrrrup, thrrrrup of a truck bouncing down a pothole-pocked street.

Others say they thought they heard phones ring while taking a shower, using a blow-dryer or watching commercials. What they are hearing is a barely discernable sound ? perhaps chimes, a faint trill or an electronic bleat ? that they mistake for the ringtone of their cellphone, which isn't ringing. This audio illusion ? called phantom phone rings or, more whimsically, ringxiety or fauxcellarm ? has emerged recently as an Internet discussion topic and has become a new reason for people to either bemoan the techno-saturation of modern life or question their sanity.

Some sound experts believe that because cellphones have become a fifth limb for many, people now live in a constant state of phone vigilance, and hearing sounds that seem like a telephone's ring can send an expectant brain into action.

"My experience has been hearing just a few notes that are similar to my phone's ring, my brain will fill in the rest," said David Laramie, a doctoral student at the Los Angeles campus of the California School of Professional Psychology, who is writing his dissertation about the effect of cellphones on behavior.

But Guy Moore, an assistant professor of physics at McGill University in Montreal, said human ears do not do a good job finding the source of sounds around 1,000 hertz using either method, so that a noise in that range seems just as likely to be coming from the television to the right as a purse sitting to the left.

"Microsoft's track record is clear," the firm says. "It consistently misses target dates for major operating system releases. We don't expect broad availability of Windows Vista until at least 2Q07 (second quarter of 2007), which is nine to 12 months after Beta 2."

Microsoft, however, maintains that everything is on schedule, in line with its March announcement.

"We respectfully disagree with Gartner's views around timing of the final delivery of Windows Vista," a Microsoft spokesman told CNET News. "We remain on track to deliver Windows Vista Beta 2 in the second quarter and to deliver the final product to volume-license customers in November 2006 and to other businesses and consumers in January 2007."

Skype, which was bought last year for $2.6 billion by online auctioneer eBay Inc., said it has nearly doubled in size from September 2005 when 54 million people were using the service.

Founded by the creators of Kazaa, the free music-sharing program that riled the music business, Skype gives away software that lets people talk for free from computer to computer, or pay a small fee to place and receive calls from regular phones.

Internet phone providers like Skype are creating upheaval in the telecommunications industry and putting pressure on traditional operators.

Though it debuted only five months ago, YouTube.com attracts 6 million visitors each day to watch two-minute video clips that amount to the Internet's version of "America's Funniest Home Videos" meets "American Idol." Every day, users stock the site with 35,000 homemade videos of lip-syncing, dancing, silly animation and commentaries on any topic, all of which are commented on and rated by viewers.

Fast Internet connections and digital video cameras are giving average people a new avenue to fame. With other homegrown phenomena such as Web logs, or blogs, and radio-style podcasts, the Internet is changing people's relationships to the media and putting more power into the hands of consumers.

Big corporations want in on the action, and giants such as Google Inc., Yahoo Inc., AOL LLC and Microsoft Corp.'s MSN have launched video sites of their own. But YouTube's do-it-yourself popularity, fueled by word of mouth, catapulted the site past its bigger competitors in months. That success is drawing the attention of mainstream media.

"Marketers are already interested in looking at how to invest in it," said Lucian James, president of Agenda Inc., a brand marketing firm. "It comes at a perfect time when brands are looking beyond the 30-second commercial and are looking for new ways to connect to their audience."
