  • Facebook rolls out revamped news feed today

    Facebook profile page

    Facebook is rolling out a new look for your news feed today. If you've been away for awhile from Facebook, the site will show you the stories it thinks are important to you first. This would be the former Top Stories view. Facebook didn't elaborate on how it determined which updates were of high importance, but they implied it would be those of close friends and family. It could also utilize your new friends lists.

    After a few top stories, your news feed will continue as normal in chronological order. This would be the former Most Recent viewing option. If you visit Facebook often and regularly, you won't get any top stories at the beginning of your news feed. That is only for users who log on infrequently.

    Facebook sees this approach similar to how newspapers layout stories. Big important news is on the front page for you to catch up on the latest and everything else behind it. Unfortunately this means the disappearance of the Top Stories and Most Recent viewing buttons. You'll only

    By going into the iPad's settings you can change your side switch's function to either mute or lock the rotation of the iPad. Most people prefer to have the side switch lock the rotation of the iPad, and use a long press of the volume button to mute (as we've already shown you).

  • Google's social network service launches with a new set of featuresGoogle+ Hangout

    After months cloaked behind an invite-only beta, the Facebook-competitor Google+ opens its doors to everyone today. With its ability to divide your friends into lists called Circles, its easy-to-use video chat feature, and the introduction of games has made the fledgling social network a hit with early adopters.

    While in beta, Google took in the feedback of its participants and today, with the formal launch of the service, it also rolled out major improvements to its video chat feature, Hangouts. The Google+ mobile app now also supports Hangouts. Right now the mobile functionality for chat only works for Android 2.3+ phones with front-facing cameras, but Google is working on support for iOS devices (watch out Facetime!).

    Other video chat improvements include the ability to display a screenshot to the other chat participants, draw a picture, write on a notepad, and share a Google Document. This will help those who use Hangouts for business or instructional purposes. In fact, Google+

  • Glowing cancer cells make tumor removal easier

    Gone are the days when the only things that glow in the dark are toys. In recent times, glow in the dark methods are used to make headway in science and medicine. Take for example, the glowing cat and dog made to help with AIDS and genetics research respectively. In the Netherlands, surgeons used a method that makes cancer cells glow to perform the first fluorescence-aided ovarian cancer surgery. The procedure is part of the first phase of a clinical trial that evaluates the fluorescence technology.

    Invented by Professor Philip Low from Purdue University, the technology enables surgeons to see cancer cell clusters as small as 1/10 of a millimeter in diameter. Without it, the smallest clusters surgeons can see average 3 millimeters in diameter only. Patients undergoing the surgery are injected with the fluorescent imaging agent a couple of hours before the procedure. The surgeons then use a multispectral fluorescence camera that shows glowing cells on a screen.

    Low says, "Ovarian

  • What is Google Wallet and how can I use it?

    Pay for your goods and service with just a tap of your phoneGoogle Wallet

    Picture a world without paper money or credit cards. You've got your smartphone in your pocket, and that's it. Want to pay for something?

    Walk up to the register, have the clerk check you out, and then tap your phone to the front of the register. The register picks up some data on your phone, and you're automatically paid for. No sliding card, no pulling out cash; just tapping your phone to the register.

    All of this is made possible thanks to technology called Near Field Communication (NFC) and Google Wallet. Today, Google Wallet became available to the public, and if you're in the right place, you can use it to pay for your stuff.

    How does Google Wallet work?
    Google Wallet works by communicating with the checkout terminal when you go to pay for goods or services. When you tap your phone to the register, your phone sends wireless data to the store, and if your phone is unlocked (with a secret PIN only you know), your products are paid for. Other than that, the transaction works just

  • Dead NASA satellite falls to Earth this week

    Decommissioned UARS finally comes home after its 20 year missionNASA climate satellite

    It sounds like something out of a sci-fi movie, right up there with robot athletes or custom-printed organs. A dead NASA climate satellite, which has been circling the earth for 20 years, will plummet from space around Friday September 23. Approximately 26 pieces of the satellite will survive the scorching heat of re-entry to eventually hit the planet. Exactly where those pieces will land is somewhat uncertain, though NASA will obviously track the satellite's descent toward Earth.

    The Upper Atmosphere Research Satellite was launched in 1991 with the scientific mission to study our atmosphere and ozone. UARS measured ozone and other chemical compounds found in the ozone layer, as well as the winds and temperatures located in the stratosphere. In 2005, NASA ordered the UARS to burn its remaining fuel, setting the stage for the satellite's eventual, inevitable suicidal plunge back to Earth.

    The debris only has a 1-in-3,200 chance to hit a person, which is considered "extremely small" by

  • China celebrates survivor pig by cloning it

    Heroic porcine DNA lives on in cloned offspringPig

    The topic of cloning tends to elicit strong feelings, whether you're for or against the idea of resurrecting fuzzy sheep, favorite pets, or wooly mammoths. But whatever your opinion of the practice, it seems somewhat appropriate to reward special animals by cloning their DNA. In that way, whatever qualities made them special in the first place might live on in their offspring after their death.

    When a devastating earthquake hit China's Sichuan province, human casualties numbered in the tens of thousands. Less well-publicized were the countless animal victims of the disaster, with one possible exception: a 330-pound, 5-year-old pig that has since been named Zhu Jianqiang, or "Strong-Willed Pig." The creature languished under the rubble of its destroyed sty for 36 days, subsisting on rainwater and charcoal, until it was finally rescued.

    Following that undoubtedly traumatic experience, scientists extracted the pig's DNA and used it to create 6 piglets, which reportedly resemble their

  • Streaming video service to remain under Netflix name, still has separate costQwikster

    Netflix is moving forward with its plan to separate its streaming video and DVD-by-mail divisions by renaming the DVD service, Qwikster. In a blog post late last night, Netflix CEO Reed Hastings apologized for how he handled the July price hike for both services, but promised it was part of a larger plan to expand and grow both divisions.

    The Qwikster name and logo will start appearing on the red envelopes users receive in the mail. The DVD portion of the Netflix website will move over the the Qwikster site which is currently under construction. Users that subscribe to both services will have separate logins and they will have to enter their credit card information again on the new site.

    To show that Netflix isn't abandoning their mail service, Reed Hastings also announced that video games will soon be available through the mail. This service, similar to the one already offered by Gamefly, has been requested for quite awhile and will cost an additional fee like Blu-ray rentals. This

  • President Obama brews up presidential beer

    Obama and Medal of Honor recipient enjoy a draft of White House Honey AlePresident Obama and Marine Sgt. Dakota Meyer

    Did you celebrate National Beer Lover's Day with a frosty cold one? It's pretty well-known that President Obama is a fan of the beverage, so there's a good chance that he did indeed crack open a bottle. When Marine Sgt. Dakota Meyer arrived at the White House to receive the prestigious Medal of Honor award for his heroism in Afghanistan, he had one request: he wanted to have a beer with the President.

    President Obama obliged, but he didn't offer your average lager or stout. Instead, the pair sipped White House Honey Ale, which Obama brewed himself from a home-brewing kit. A select few enjoyed the President's first foray into fermentation at a Super Bowl party held at the White House earlier this year, and they've been brewing small batches ever since.

    Homebrewing beer is a small but growing industry, and is perfectly legal in most states. Many states do limit the amount any one household can brew each year, though, and you can't sell it without a license. And lest anyone complain

  • The International Space Station has a great view of Earth, and offers a unique opportunity to document both good and bad events on our fair planet. In this video, science educator James Drake created a new perspective on Earth, as seen from the ISS.

    Drake downloaded a series of 600 photographs from NASA's Gateway to Astronaut Photography of Earth website (which contained 637,572 photos taken from the ISS, as of September 1, 2011), and then turned the photos into a time-lapse video. Beginning over the Pacific Ocean, you can see the lights of cities including Seattle, Portland, San Francisco, Los Angeles, and others as the ISS moves over North and South America and heads toward daylight near Antarctica.

    You can see this video and an impressive collection of other beautiful space-related images at James Drake's Tumblr blog.
