Last week, Google released a beta application that provides walking directions in major cities such as New York, San Francisco, and Minneapolis. It's another sign that the search giant is getting even more specific about "organizing the world's information," right down to the sidewalk in front of your house. If you want to walk from your apartment in the suburbs to a restaurant downtown, Google will show you the best route with turn-by-turn directions you can print out or follow on your smartphone.

Google added its own version of life to the Web this week with its launch of the animated program "Lively." A "20 percent project"—one borne from Google's policy of allowing its staff to spend 20 percent of their work time on their own projects—Lively is much like another Second Life. Its users can enter 3-D worlds, engage in real-time avatar interactions and express their thoughts and feelings all in a virtual community. What distinguishes it, though, from its competition is that it can be controlled from any Web page.

Crunching massive, geographical data visualizations used to require expensive mapping software and powerful computers. Now, Google Earth is becoming the go-to application for scientists who need a cheap way to animate huge sets of 3-D data right on their home desktop. These five projects show how a simple tool can reveal hidden patterns in everything from ash to emotions.

Space Adventures, the broker of the first tourist flights to space celebrated its ten-year anniversary today here at the Explorer's Club in New York with the announcement that it had scored a deal with the Russian Federal Space Agency, or RKA, to buy an entire flight to the International Space Station.

When Google squelched rumors of the all-powerful “G-phone” last November, we admit we were a bit bummed. Instead of an inexpensive smartphone that would free us from our carrier overlords, Google had been working on software—an open-source, mobile operating system called Android. Great name, but will unlocking cellphone code really change things for consumers?

Miner says that more than 750,000 developers have downloaded the tool required to write an Android-based program, four times as many as accessed the iPhone’s tightly regulated kit. That means Android users could have far more mobile applications to choose from. But we still don’t know how those apps will stack up next to Apple’s. Android-equipped phones—set to go on sale this summer—should be less expensive than the iPhone, since manufacturers won’t have to pay licensing fees for the software. But instead of getting free, ad-subsidized service, like Google’s e-mail, you’ll still shell out to carriers. Which makes us wonder: Is this really so new, or just another offering in the crowded mobile market? We spoke with Rich Miner, head of Google’s mobile-platform division, for some clarity.

Google is slowly turning its Maps application into a wiki and that looks to be a very good thing. Sidewalk—and later Citysearch—only ever had enough staffing resources to scrape the surface of any particular city. Google Maps, on the other hand, has the entire online populace at the ready. While Citysearch in recent years has opened its site to community reviews, it has not given users control over all the data. That's where Google Maps is headed.

The Office of the United Nations High Commissioner for Refugees (UNHCR) has teamed up with Google to give anyone with Web access a chance to see what life and conditions are like in a refugee camp. The initial iteration centers on Chad, Iraq, Colombia and Darfur.

Web surfers can explore camps through the visual, textual, audio and video information that's layered on top of the bigger picture. Pop-up windows throughout the images of the camps tell you what's going on, and what's needed. You can also move in close enough to examine the infrastructure, including schools and other facilities.

Woe is the Internet on April 1. For it is on this day where sites large and small rack their brains for the perfect Fools' Day prank, briefly vindicating those that continue to hold the belief that the Web serves as nothing more than a sloppy ocean of untruths and nonsense.

At this point we've known for a while that the much-talked-about gPhone isn't actually going to be a single device, but a whole slew of them running Google's Android platform, but that doesn't mean the buzz is dying out. Now CNET says there's a new race heating up, as Google and Apple vie for the attention of independent software developers.

Yahoo yesterday joined Googles recently launched OpenSocial network. OpenSocial is built on APIs that let developers build applications to run on any participating social network. It gives the programs access to user data, relationships, and event postings across the board. For example, if the wildly popular Facebook application Scrabulous had been built for OpenSocial, it would work on any network under the OpenSocial umbrella, not just Facebook.

Google says the US government is ignoring a precious natural resource. And no, the search giant obviously isn't talking about oil. Google, along with other big companies, wants the US government to open up unused air waves. The company says this could lead to people across the country surfing the Web on handheld devices at gigabits-per-second speeds.

Yahoo surprised analysts yesterday, announcing that it is on track to meet its expected earnings for 2008. This changes the fight between the Sunnyvale-based company and Microsoft, which recently offered to pay $42 billion to swallow it up. Now Yahoo has a bit more leverage, and may be able to convince investors that its not in such bad shape after all. The company says it expects to double its cash flow and increase its revenue by 50 percent, mostly from banner and video advertising.

For years, Ask.com has been trying to supplant Google as the Internets search leader, but this week the company has announced that it is headed in another direction. In truth, Ask never really got all that close.
