Silent Skype calls can hide secret messages

Got a secret message to send? Say it with silence. A new technique can embed secret data during a phone call on Skype. "There are concerns that Skype calls can be intercepted and analysed," says Wojciech Mazurczyk at the Institute of Telecommunications in Warsaw, Poland. So his team's SkypeHide system lets users hide extra, non-chat messages during a call.

Mazurczyk and his colleagues Maciej Karaś and Krysztof Szczypiorski analysed Skype data traffic during calls and discovered an opportunity in the way Skype "transmits" silence. Rather than send no data between spoken words, Skype sends 70-bit-long data packets instead of the 130-bit ones that carry speech.

The team hijacks these silence packets, injecting encrypted message data into some of them. The Skype receiver simply ignores the secret-message data, but it can nevertheless be decoded at the other end, the team has found. "The secret data is indistinguishable from silence-period traffic, so detection of SkypeHide is very difficult," says Mazurczyk. They found they could transmit secret text, audio or video during Skype calls at a rate of almost 1 kilobit per second alongside phone calls.

The team aims to present SkypeHide at a steganography conference in Montpellier, France, in June.

Tennis: Williams races to Brisbane title win

BRISBANE, Australia: American superstar Serena Williams demolished Russia's Anastasia Pavlyuchenkova 6-2, 6-1 in just 50 minutes to win the Brisbane International on Saturday.

Third-seeded Williams served notice that she will be the one to beat at this month's Australian Open with a ruthless display against Pavlyuchenkova, the world number 36.

She took control at 2-2 in the first set when she went on a run of seven straight games and never looked like losing against an increasingly demoralised opponent, who had no answer to Williams' power and aggression.

Williams sent down nine aces and won 91 per cent of her first serves, blasting 24 winners past Pavlyuchenkova, who looked shell-shocked at times with the pace of the American's groundstrokes.

Williams, 31, has now won 47 titles on the WTA tour and lost only once since the French Open last year, winning 35 of her past 36 matches.

Although ranked third in the world, Williams is a firm favourite for the Australian Open on the strength of her efforts in the second half of 2012, when she won Wimbledon, the US Open, the WTA Championship and the Olympics.

Library of Congress digs in to full archive of 170 billion tweets

The U.S. Library of Congress said today that it has completed a process of collecting a full, ongoing stream of tweets, and that it has begun work to archive and organize more than 170 billion tweets.

Under an agreement struck between the government institution and Twitter in 2010, the microblogging company is providing the Library of Congress with a full stream of all public tweets, starting with 21 billion generated from between 2006 and April 2010, and now supplemented with about 150 billion more posted since then.

In an announcement about the status of the project today, the library wrote that:

Twitter is a new kind of collection for the Library of Congress but an important one to its mission. As society turns to social media as a primary method of communication and creative expression, social media is supplementing, and in some cases supplanting, letters, journals, serial publications, and other sources routinely collected by research libraries.

Though the Library has been building and stabilizing the archive and has not yet offered researchers access, we have nevertheless received approximately 400 inquiries from researchers all over the world. Some broad topics of interest expressed by researchers run from patterns in the rise of citizen journalism and elected officials' communications to tracking vaccination rates and predicting stock market activity.

The Library of Congress isn't entirely clear how the ongoing archive will be utilized, but it has issued a white paper (PDF) outlining the project.

This project, of course, is different than Twitter's recently announced initiative to make every user's full tweet history available to them. That effort is under way, though only some users have been given access to date.

Interestingly, the Library of Congress reported in the white paper that its two full copies of the entire archive of 170 billion tweets comprise about 133 Terabytes of data. Each tweet, the library wrote, contains about 50 accompanying metadata fields.

Quadruple Amputee Gets Two New Hands on Life

It's the simplest thing, the grasp of one hand in another. But Lindsay Ess will never see it that way, because her hands once belonged to someone else.

Growing up in Texas and Virginia, Lindsay, 29, was always one of the pretty girls. She went to college, did some modeling and started building a career in fashion, with an eye on producing fashion shows.

Then she lost her hands and feet.

Watch the full show in a special edition of "Nightline," "To Hold Again," TONIGHT at 11:35 p.m. ET on ABC

When she was 24 years old, Lindsay had just graduated from Virginia Commonwealth University's well-regarded fashion program when she developed a blockage in her small intestine from Crohn's Disease. After having surgery to correct the problem, an infection took over and shut down her entire body. To save her life, doctors put her in a medically-induced coma. When she came out of the coma a month later, still in a haze, Lindsay said she knew something was wrong with her hands and feet.

"I would look down and I would see black, almost like a body that had decomposed," she said.

The infection had turned her extremities into dead tissue. Still sedated, Lindsay said she didn't realize what that meant at first.

After Hand Transplant, Relearning How to Hold Watch Video

"There was a period of time where they didn't tell me that they had to amputate, but somebody from the staff said, 'Oh honey, you know what they are going to do to your hands, right?' That's when I knew," she said.

After having her hands and feet amputated, Lindsay adapted. She learned how to drink from a cup, brush her teeth and even text on her cellphone with her arms, which were amputated just below the elbow.

"The most common questions I get are, 'How do you type,'" she said. "It's just like chicken-pecking."

PHOTOS: Lindsay Ess Gets New Hands

Despite her progress, Lindsay said she faced challenges being independent. Her mother, Judith Aronson, basically moved back into her daughter's life to provide basic care, including bathing, dressing and feeding. Having also lost her feet, Lindsay needed her mother to help put on her prosthetic legs.

"I've accepted the fact that my feet are gone, that's acceptable to me," Lindsay said. "My hands [are] not. It's still not. In my dreams I always have my hands."

Through her amputation recovery, Lindsay discovered a lot of things about herself, including that she felt better emotionally by not focusing on the life that was gone and how much she hated needing so much help but that she also truly depends on it.

"I'm such an independent person," she said. "But I'm also grateful that I have a mother like that, because what could I do?"

Lindsay said she found that her prosthetic arms were a struggle.

"These prosthetics are s---," she said. "I can't do anything with them. I can't do anything behind my head. They are heavy. They are made for men. They are claws, they are not feminine whatsoever."

For the next couple of years, Lindsay exercised diligently as part of the commitment she made to qualify for a hand transplant, which required her to be in shape. But the tough young woman now said she saw her body in a different way now.

German minister says "never again" to nuclear power

BERLIN: German Environment Minister Peter Altmaier said on Friday his country would never again return to nuclear energy, hitting back at a top EU official who doubted Berlin's commitment to phase out nuclear power.

"I cannot see any plausible political line-up that would enable a revival of nuclear power in Germany," Altmaier told Friday's edition of the Leipziger Volkszeitung regional daily.

After the 2011 Fukushima disaster in Japan, Germany embarked on an ambitious "energy revolution", deciding to phase out its nuclear power plants by the end of 2022 and bolster renewable sources of energy such as solar and wind power.

However, concerns have mounted that this would entail a sharp rise in electricity prices amid difficulties in building a network able to transmit energy from the North Sea coast to the energy-hungry south of the country.

The European Union's Energy Commissioner, Guenther Oettinger, told Monday's edition of the Rheinische Post regional daily that there would "still be nuclear power on the German network in 40 years."

He said there were still 140 nuclear power stations in Europe and that nuclear fusion technology was progressing rapidly. "Maybe this technology will one day be accepted in Germany," said Oettinger, himself German.

Altmaier also vowed to find a permanent national storage site for nuclear waste by 2030. "We are together looking country-wide," he said, adding that the search would be accelerated in the coming years.

The search would be "co-financed and jointly carried out" by Germany's nuclear energy companies, he said.

The 10 biggest tech innovations (that we personally use) of our lifetimes

Next-train arrival signs, like this one for NYC subway system have revolutionized commutes. Screen shot: Instragram photo by Sree Sreenivasan

As the father of 9-year-old twins, I often find myself telling them about tech products and innovations that I didn't have growing up. All parents do it: trying to get their kids to understand how much tougher life was in the old days.

In my case, the old days were in the 1980s - not that long ago. But the range of change in our lives continues to impress me and make my children roll their eyes.

Yesterday, I posted a photo on Instagram (see above and on my Sreenet account), saying the NYC subway's next-train arrival guides are among the top 20 technology innovations of my lifetime.

As you can tell, I had to post in a hurry as the next train arrived two minutes later. As I stood inside the subway, blissfully without cell service, I had a chance to think about that concept of top tech innovations and asked myself whether those guides were, indeed, worthy of a top 20 listing.

I've now taken a shot at that list. Before you read it, some ground rules I gave myself:

• The technology had to be for personal use, something that affected me and that I use myself. So innovations in space travel, nuclear physics and enterprise computing don't count.


• Innovations that have benefited millions of others, but I don't personally use don't count (sorry, electric
  car).


• They had to be widely available only after my teen years - i.e, around 1988 - to be considered (eliminating the Walkman, the CD, the home video camera, the microwave oven).


• Innovations so new or so rare or so expensive - or all three - that my family couldn't acquire them until many years later, do count (some of the items below might have been under your Christmas tree, but not mine).


• Innovations that were widely adopted but then became irrelevant in their original form aren't here (example: America Online, Compuserve, etc).
  
• Tech products that are mostly an evolution from something prior don't count (therefore, the DVD doesn't make the list; it's too similar to its predecessors, Betamax, VHS and laserdisc).
  
• And if I saw my dad using it, it doesn't count, even if it's wonderful and I use it every day (sorry, electric razor).

Basically, it has to be stuff I didn't have when I was a kid.

What would be on your version of this list? Here's mine (the first six are in order of importance; the rest aren't):

1. The Internet/Web/Search: No explanation needed.


2. Email: Electronic messaging recently celebrated its 30th anniversary, but it wasn't a true mass product until the mid-1990s.


3. Cellphones and smartphones: Cellphones have been around for decades, but the true revolution has only happened since the mid-1990s.


4. Digital cameras: These cameras changed the way I capture and share memories and how I see the worlds of my friends, family and complete strangers. While more of my friends than ever before sling fancy digital SLRs, the only digital camera I've used in the last 15 months or so is the one in my iPhone. The other day, when someone took a group portrait with a point-n-shoot digital camera, several of us in the picture commented on how long it had been since we had used an "old-fashioned" camera.


5. Laptops and wifi: Sure, there were ridiculously expensive laptops around in the 1980s, but none had the transformative effect on my life the way the ones in the 1990s did. And the arrival of wifi freed those laptops from the suffocating ethernet cord.


6. GPS (with a nod to web-based Mapquest and Google Maps): I still remember our car vacations started with my dad would going down to the AAA (Wikipedia tells me it was "known formerly as the American Automobile Association" - sort of like IBM, I guess) and get maps with our route highlighted in yellow. When I first saw Mapquest I was blown away by the potential; the arrival of Web-based Google Maps just continued the innovation and set the stage for how we all use GPS today.

   My friend Arik Hesseldahl (@AHess247) of AllThingsD once explained to me, for another story, how cool technology by itself isn't likely to change the landscape. Luck and government decisions play a role, too:
   

   GPS existed [prior to 1997], but was deliberately made inaccurate for non-military users under a federal directive known as "selective availability" that was eliminated in 2000 by order of President Clinton; prior to this, consumer GPS was good enough for hiking, but nowhere near good enough for in-car navigation, let alone geocaching.



7. MetroCard: Prior to the arrival of these yellow electronic payment cards for the subway, New Yorkers had to be obsessed with having enough tokens on hand to enter the system. The MetroCard literally changed my life.


8. Next-train arrival signs: Londoners and Londonphiles love to tell me how they've had these forever in the Underground, but these arrived in NYC only three years ago. Until these real-time signs showed up, you had no idea if your train was coming in two minutes or 20. Just last week, a handy next step: MTA Subway Time, an iPhone app that gives you the same real-time arrival data. It was officially released only for iOS, but, in a sign of the times, someone made an Android version within 24 hours, thanks to the Metropolitan Transportation Authority's API offerings (more on APIs below). Yes, it's only for a few subway lines, but 90 percent of my trains are covered and this is my list, after all.


9. Wii and Kinect: When I was growing up, Atari, Intellivision and Commodore were major players in the home console market. The systems that came after that were much more powerful and more popular, but were basically improvements on what came before (sorry, Sega, Nintendo 64,
   PlayStation, Xbox). But the
   Wii, which I first tested at a family gathering on Thanksgiving 2006, was a breakthrough worthy of this list. I saw something I'd never seen before: Grandparents, parents and kids all gathered around the big-screen TV, playing digital bowling, golf and tennis.

   Some of that may have happened on occasion in the Atari days, but now, the players were all standing, not sitting on a couch, thanks to the wireless remotes. I predicted on my local TV segment the following week that the Wii would be unlike any other video game product and outsell the competition. At the time and in the years to follow, gamer-snobs felt the Wii wasn't any good in comparison to consoles with fancier graphics, better sound and more complex - and more gruesome - titles. The Wii went onto to outsell the other so-called "seventh generation" consoles, including PlayStation 3 and Xbox 360.

   A logical next step in gaming has to be on my list. The Microsoft Kinect sensor, which works on Xbox, does away with the wireless remote and uses a player's arms and entire body to control the games - everything from sports to dance-offs. As I wrote in January 2011 about Five Things I Learned from Two Weeks With Kinect, this is only the beginning. "The Kinect shows that there's still lots of room for innovation in a field that seemed pretty saturated. I expect to see more developments in this area as the sensors gets smarter, the cameras gets sharper and the game play gets more sophisticated.



10. Social media, including blogging: Here I'm including various platforms - Facebook, Twitter, LinkedIn, blogging - that have changed the way a billion-plus people spend their time, express themselves and engage with each other. For better and worse.


11. Wikipedia: While it's easy to complain about some of the problems of Wikipedia, the fact is that it has completely changed the way I do everyday research. It's my first stop, not my last - and I sometimes spend as much time on the footnotes and where they lead as I do on the main text. Even hoaxes like the one uncovered last week don't deter me (see Bicholim Conflict on this list of the biggest hoaxes in Wikipedia history). If you want to truly understand Wikipedia's impact, potential and pitfalls, you have to read the definitive book about it, "The Wikipedia Revolution: How A Bunch of Nobodies Created The World's Greatest Encyclopedia" by my friend Andrew Lih (@fuzheado).


12. YouTube: I had considered not including YouTube because it is, in many ways, just an evolution in online video. But in recent years, YouTube has become its own community with four billion hours of video watched every month; an important tool for all kinds of marketing, promotion and propaganda; and a source of entertainment and information for 800 million people every month (a stat I found in this compelling Peter Kafka (@pkafka) post that makes that case that Al Jazeera English should have gone with a web-only platform, rather than buying Current TV as announced this week).


13. Zipcar: This car-sharing service changed my family's life, allowing us to access a car in more convenient ways than traditional rental cars (we don't own a car, in part, because parking in our Manhattan building is $500 a month). This week's purchase of Zipcar by Avis for $500 million is causing consternation. Here's an article saying this is good for consumers; here's one that argues the opposite.


14. Credit cards in NYC taxis: Until they came along, I had to always check my wallet for cash before grabbing a taxi. Since they became widely available in 2007, I've not had to hesitate before hailing a cab and, unlike some folks who complain about drivers unhappy to take cards, I've never faced an issue with that.

    There's another reason to use credit cards in cabs, as I wrote in 5 Lessons From a Lost iPhone: "3. I'll always pay for my NYC cabs with credit cards. Turns out the taxi medallion number (the unique number displayed on top of all yellow cabs in Manhattan) is recorded with every credit card purchase, meaning you have way of tracking down cabs you've taken." The taxi industry in the city is the process of a much bigger disruption: figuring out new apps that are changing the decades-old system of hailing cabs.



15. DVR: The arrival of TiVo, and, later, the generic digital video recorder provided by the cable company, introduced us all to timeshifting TV in ways the complicated VHS system and its blink "12:00" clock never could.


16. Netflix: I'm including Netflix here as a representative of a whole new class of video watching, a big leap from the DVR. Whether Netflix will be the eventual winner in this space or not (Amazon, Hulu and others are attacking it), the concept of getting movies anytime from anywhere has changed how our family accesses entertainment.

    But I don't understand how anyone uses Netflix without also accessing Instawatcher.com, which provides a much better, searchable listing of the on-demand movies on Netflix, including my favorite feature, "Expiring soon."

    If you don't want to spring for Netflix, but are an HBO subscriber, you have to check out the free HBO Go app or website, which provides access to dozens of movies and entire seasons of HBO shows that are no longer available on the HBO On Demand service on your cable box. For instance, I saw and enjoyed "The No. 1 Ladies Detective Agency," a quirky, charming show I never saw when it first ran on the network.



17. iPod and iTunes: These changed the music world forever, let us carry thousands of songs at a time and got millions of us to pay for digital music for the first time.

    My friend Hari Sreenivasan (@Hari; no relation), now an anchor on PBS Newshour, was the first to outline to me the power of iPod beyond music. One day in late 2001 (soon after iPod was launched), he predicted that the iPod would be a great way to introduce the Apple brand to PC users skeptical of the Mac. He saw it as a way to get people comfortable using an Apple product and getting them hooked and ready to try others. Even though he didn't call it that, iPod became a gateway drug that changed the company's fortunes and set it on the path to iPhone, iPad and beyond. If you are curious, the price of Apple stock on Oct. 1, 2001 was $15.49. On Oct. 1, 2012, it was $671.16 (it's down since then).



18. Tablets and apps: In some ways, tablets feel like cousins of laptops and not worthy of this list. But in many other ways, they are, indeed, new. The key here are the apps we use in smartphones, too. As millions of users have discovered, tablets can be used in ways that are different from laptops and we see them being used as cash registers, restaurant menus, medical devices and much more. And all this is just getting started.

    I didn't include e-readers such as the Kindle on this list because while they were innovative, they are not going to stick around much longer. Thanks to tablets that let you read Kindle content without a Kindle, e-readers are dying much faster than anyone could have predicted. See this chart to understand the whole picture.



19. APIs: I am not an engineer, but I play one on TV, thanks to my CNET tech segments on WCBS-TV. Since I don't program, it's not obvious why I'd include APIs - or application programming interfaces - on this list.

    But these web APIs, which allow live data and content from one web service to be posted and used on another have changed how we access information. Everything from mashups of real-estate listings and Google maps, to embedding videos, to the subway-arrival app I mentioned in #7 above, APIs are now a critical part of our digital lives. Here's a list of the most popular APIs.



20. Cordless irons: I know some of you will claim to have had cordless electric irons for decades now, but the day I saw one of these, I had to have one when the prices became reasonable. They aren't as good as corded ones (the heat dissipates too quickly), but they changed my ironing life.

That's my 20. Am sure I am missing some others and that you will disagree with many of my choices (especially if you are in a different age bracket). That's what makes this list so much fun to put together. It has no right or wrong answers and it's all about you.

Hope you'll take a stab at creating a similar list of 5-20 tech innovations. You can post it in the comments below and/or tweet it with #mytoptech.

Pictures We Love: Best of 2012

Photograph by Mindy Schauer, Orange County Register/AP

Powder-splattered, and powder-splattering, runners cross the finish line of The Color Run 5K in Irvine, California, on April 22. Each kilometer (0.6 mile) of the event features a color-pelting station dedicated to a single hue, culminating in the Pollock-esque riot at kilometer 5.

The "magical color dust" is completely safe, organizers say, though they admit it's "surprisingly high in calories and leaves a chalky aftertaste."

Ex-USC Player: Painkiller Injections Caused Heart Attack

Despite stated label risks of possible fatal heart attack, stroke or organ failure, college football players across the country are still being given injections of a powerful painkiller on game days so they can play while injured, an ABC News investigation has found.

The drug, a generic version of Toradol, is recommended for the short-term treatment of post-operative pain in hospitals but has increasingly been used in college and professional sports, and its use is not monitored by the NCAA, the governing body of college sports.

Only two of the country's top football programs, Oklahoma and the University of Nebraska, reported to ABC News that they have limited or stopped the use of the drug in the wake of growing concern about its risks.

Which Top-Ranked College Football Teams Use Toradol?

Oklahoma said it stopped using the painkillers in 2012 after using them repeatedly in 2010 and 2011.

Nebraska said its doctors now restrict its use.

SEND TIPS About Painkiller Use in College Sports to Our Tipline

"While team physicians reserve the option to use injectable Toradol, it is rarely prescribed, and its use has been avoided this season following reports of heightened concern of potential adverse effects," Nebraska said in a statement to ABC News.

Despite Risks, College Football Still Uses Powerful Painkiller Watch Video

The top two college football programs, Notre Dame and Alabama, refused to answer questions from ABC News about the painkiller. They play for the national college championship on Jan. 7.

Controversy surrounding the drug has grown this year following claims by former USC lineman Armond Armstead that he suffered a heart attack after the 2010 season, at age 20, following shots of generic Toradol administered over the course of the season by the team doctor and USC personnel.

"I thought, you know, can't be me, you know? This doesn't happen to kids like me," Armstead told ABC News.

The manufacturers' warning label for generic Toradol (ketorolac tromethamine) says the drug is not intended for prolonged periods or for chronic pain and cites gastrointestinal bleeding and kidney failure as possible side effects of the drug.

In addition, like other drugs in its class, the generic Toradol label warns "may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction (heart attack), and stroke, which can be fatal."

"This risk may increase with duration of use," the so-called black box warning reads.

In a lawsuit against the school and the doctor, Dr. James Tibone, Armstead claims the school ignored the stated risks of the drug and never told him about them.

"He was a race horse, a prize race horse that needed to be on that field no matter what," said Armstead's mother Christa. "Whether that was a risk to him or not."

Armstead says he and many other USC players would receive injections of what was known only as "the shot" in a specific training room before big games and again at half-time.

"No discussion, just go in. He would give the shot and I would be on my way," Armstead told ABC News.

Armstead said the shot made him feel "super human" despite severe ankle, and later shoulder pain, and that without it, he never could have played in big USC games against Notre Dame and UCLA.

"You can't feel any pain, you just feel amazing," the former star player said.

USC declined to comment on Armstead's claims, or the use of Toradol to treat Trojan players.

An ABC News crew and reporter were ordered off the practice field when they tried to question USC coach Lane Kiffin about the use of the painkiller. USC says the ABC News crew was told to leave because they had not submitted the appropriate paperwork in advance to attend the practice session.

Marine Life Park dolphins released from quarantine

SINGAPORE: The dolphins at Resorts World Sentosa's Marine Life Park have been released from quarantine and is expected to meet the public soon.

The park said the 24 dolphins have received the Agri-food and Veterinary Authority of Singapore's (AVA) approval for their release.

It added the mammals have adjusted well to their new home through the care of its staff and veterinary professionals.

The park looks forward to let the dolphins meet the public through progressive stages of introduction.

It also gave updates on the laboratory tests on the male dolphin that died on the flight to Singapore from the Philippines.

The final pathology report indicated that Wen Wen had succumbed to an acute bacterial infection.

There was, however, no evidence on the origins of the infection.

Medical examinations prior to the transport indicated that all animals were healthy prior to the move.

The park believes the infection was an isolated incident.

Recently, the park attracted controversy for its import of dolphins.

WhatsApp has a message for its users -- a lot of them.

The mobile messaging service announced today that it set a WhatsApp record on New Year's Eve, processing 18 billion messages on the last day of the year. The company said it delivered 7 billion inbound messages and 11 billion outbound messages, surpassing its previous record of 10 billion messages processed in August.

In comparison, Apple revealed in October that its iMessage text service had delivered about 300 billion texts sent by iOS users during the previous 12 months -- an average of less than a billion a day.

That kind of growth reportedly attracted acquisition interest from Facebook -- a TechCrunch report that the company called "a rumor and not factually accurate."

Founded in 2009, the Santa Clara, Calif.-based company provides a smartphone app for
Android, BlackBerry, iOS, Symbian, and Windows Phone that delivers text messages, as well as images and audio and video messages.

Pictures: Errant Shell Oil Rig Runs Aground Off Alaska, Prompts Massive Response

Photograph courtesy Jonathan Klingenberg, U.S. Coast Guard

Waves lash at the sides of the Shell* drilling rig Kulluk, which ran aground off the rocky southern coast of Alaska on New Year's Eve in a violent storm.

The rig, seen above Tuesday afternoon, was "stable," with no signs of spilled oil products, authorities said. But continued high winds and savage seas hampered efforts to secure the vessel and the 150,000 gallons (568,000 liters) of diesel fuel and lubricants on board. The Kulluk came to rest just east of Sitkalidak Island (map), an uninhabited but ecologically and culturally rich site north of Ocean Bay, after a four-day odyssey, during which it broke free of its tow ships and its 18-member crew had to be rescued by helicopter.

The U.S. Coast Guard, state, local, and industry officials have joined in an effort involving nearly 600 people to gain control of the rig, one of two that Shell used for its landmark Arctic oil-drilling effort last summer. "This must be considered once of the largest marine-response efforts conducted in Alaska in many years," said Steve Russell, of Alaska's Department of Environmental Conservation.

The 266-foot (81-meter) rig now is beached off one of the larger islands in the Kodiak archipelago, a land of forest, glaciers, and streams about 300 miles (482 kilometers) south of Anchorage. The American Land Conservancy says that Sitkalidak Island's highly irregular coastline traps abundant food sources upwelling from the central Gulf of Alaska, attracting large numbers of seabirds and marine mammals. The largest flock of common murres ever recorded by the U.S. Fish and Wildlife Service was in Sitkalidak Strait, which separates the island from Kodiak. Sitkalidak also has 16 wild salmon rivers and archaeological sites tied to the Alutiiq native peoples dating back more than 7,000 years.

Shell incident commander Susan Childs said Monday night that the company's wildlife management team had started to assess the potential impact of a spill, and would be dispatched to the site when the weather permitted. She said the Kulluk's fuel tanks were in the center of the vessel, encased in heavy steel. "The Kulluk is a pretty sturdy vessel," she said. " It just remains to be seen how long it's on the shoreline and how long the weather is severe."

Obama Signs 'Fiscal Cliff' Bill With Autopen

Jan 3, 2013 12:53am

Charles Dharapak/AP Photo

HONOLULU, Hawaii — President Obama has signed the “fiscal cliff” legislation into law via autopen from Hawaii, where he is vacationing with his family.

The bill to avert the “fiscal cliff” arrived at the White House late this afternoon and it was immediately processed, according to a senior White House official. A copy was delivered to the president in Hawaii for review. He then directed the bill to be signed by autopen back in Washington, D.C.

The Bush administration deemed in 2005 that the use of the autopen is constitutional, although President George W. Bush never used the mechanical device to replicate his signature on a bill.

The office of legal counsel found at the time that Article 1, Section 7 of the Constitution allows the president to use the autopen to sign legislation, stating “the President need not personally perform the physical act of affixing his signature to a bill to sign it.”

Obama has used the autopen twice in the past to sign legislation, both times while he was overseas.

Use of the autopen has been controversial.  Conservative groups alleged last summer that Obama used an autopen to sign condolence letters to the families of Navy SEALs killed in a Chinook crash in Afghanistan — a charge the White House disputed flatly as false.

In 2004, then-Secretary of Defense Donald Rumsfeld was criticized for using an autopen to sign condolence letters to the families of fallen troops.

And in 1992 then-Vice President Dan Quayle even got into some hot water over his use of the autopen on official correspondence during an appearance on “This Week with David Brinkley.”

Obama, who arrived back in Hawaii early Wednesday morning to continue his family vacation, spent the afternoon golfing with friends at the Marine Corps base at Kaneohe Bay.

Obama is slated to remain in Hawaii through Saturday.

Stone-age cinema: Cave art conceals first animations

Sandrine Ceurstemont, editor, New Scientist TV

Think the first movies were screened in a cinema? According to an analysis of cave art, our prehistoric ancestors may have invented the concept while drawing on their walls.

In this video, researcher and film-maker Marc Azema from the University of Toulouse Le Mirail in France reveals how several frames of an animation are superimposed in many animal sketches. A horse painting from the Lascaux caves in France, for example, is made up of many versions of the animal representing different positions of movement. In this video, Azema extracts the individual images and displays them in succession, demonstrating how they play back like a cartoon.

In other examples, motion is represented by juxtaposing drawings of a body in motion. Azema creates another sequence by picking out motion frames to produce an animation of a running animal.

Apart from layered paintings, ancient humans may have used light tricks to evoke motion on cave walls. Engraved discs of bone have also been found which produce galloping animations when spun on a string, reminiscent of flipbooks. For more on prehistoric cinema, read our feature article, "Prehistoric cinema: A silver screen on the cave wall".

Eurozone manufacturing shrinks in December

BRUSSELS: Eurozone manufacturing activity contracted for a 17th month running in December, a key survey of business managers showed on Wednesday.

The Purchasing Managers Index (PMI) for the manufacturing sector, a leading indicator compiled by the Markit research firm, came in at 46.1 points in November, down from an earlier estimate of 46.3 points and down from November's 46.2 points.

Any score below 50 points indicates contraction, not growth.

Ireland, as has frequently been the case in recent months, posted a score of 51.4 points, indicating growth.

But Germany (46.0 points), France (44.6) and Italy (46.7) were all signalling contraction.

While manufacturing activity "may have suffered its worst contraction around October," said London-based IHS Global Insight analyst, "the December purchasing managers' surveys indicate that the sector is still stranded well into recessionary territory."

Wireless trade group CTIA to drop one conference

Wireless trade group
CTIA said today that it will go from two shows a year to a single conference in the fall starting in 2014.

The group, which is primarily focused on the U.S. wireless industry and includes carriers, handset manufacturers, and other related companies, has traditionally held two shows each year: a larger main show in the spring and a smaller, more business-focused event in the fall called MobileCon. The group will continue to hold both events this year.

Pressured by competing trade shows and its own members, CTIA will merge the conferences into a single "super show" in the fall, which it has coined "Super Mobility Week."

"I believe the show will be bigger than the two combined," said Rob Mesirow, show director and vice president of the CTIA.

The main show has long been considered an also-ran event because of its unfortunate scheduling. The CTIA Wireless show comes after the larger Consumer Electronics Show and Mobile World Congress, which often steal away many of the major announcements. The second fall show has always been much smaller in scale and attracted a more limited crowd.

By focusing its efforts on a single fall show, CTIA hopes to provide its members with a platform to make product announcements for the holiday season, Mesirow said in an interview.

"A lot of small events take place in the second half, but there isn't one large event with gravitational pull, and what we found is companies are looking for a place to make product announcements for the holiday season," he said.

Still, even the larger shows are starting to see their own relevance wane as companies opt to hold their own events. Apple has long shunned conferences, and Microsoft has pulled out of
CES. This past spring, Samsung opted to skip CTIA all together, instead holding meetings and presentations in the same city but away from official show grounds. Samsung had announced its Galaxy S III flagship smartphone at its own event a little before CTIA.

Still, CTIA believes the confluence of media, industry observers and executives, and retailers at a single show make for an attractive site for companies that may not have the cachet to pull off their own event.

MobileCon is the name of the fall CTIA show.

Mesirow said he believes the 2014 CTIA show will be bigger by including more facets of the mobile industry, including networking companies, machine-to-machine providers, global consumer electronics companies, connected home companies, media companies, and advertising.

"It's a holistic vision of where the wireless industry is moving," he said, noting there would be several "show within a show" areas addressing those different categories, including MobileCon, and new strategic partners. Mesirow wouldn't comment on who those new partners may be.

Mesirow said the trade group has been working on the concept for the last two years, and made the decision this year after polling its members. Many of the larger industry players have complained that the two conferences and the obligation to show up were often a drain on resources.

The CTIA, meanwhile, has added Apple as a board member, and while the company isn't likely to show up at its trade show, the group will have a new "iZone" area focused on the Apple ecosystem.

  NASA's Solar Dynamics Observatory snapped this extreme ultraviolet view of an active region on the sun as it rotated into view from December 16 to December 18. Ultraviolet light makes it easier to trace the whorls and loops created by superheated gas, or plasma, and the sun's magnetic field lines.

  Active solar regions such as this create space weather that, when aimed at Earth, can disrupt satellite communications and electronics. (See more pictures of solar activity and space weather.)

Obama Hails 'Cliff' Deal, Warns of Next Fiscal Fight

Minutes after the House of Representatives approved a bipartisan Senate deal to avert the "fiscal cliff" and preserve Bush-era tax cuts for all Americans making less than $400,000 per year, President Obama praised party leaders and wasted little time turning to the next fiscal fight.

"This is one step in the broader effort to strengthen our economy for everybody," Obama said.

Obama lamented that earlier attempts at a much larger fiscal deal that would have cut spending and dealt with entitlement reforms failed. He said he hoped future debates would be done with "a little less drama, a little less brinksmanship, and not scare folks quite as much."

But Obama drew a line in the sand on the debt ceiling, which is set to be reached by March.

"While I will negotiate over many things, I will not have another debate with this Congress over whether they should pay the bills for what they've racked up," Obama said. "We can't not pay bills that we've already incurred."

An hour after his remarks, Obama boarded Air Force One to rejoin his family in Hawaii, where they have been since before Christmas.

'Fiscal Cliff' Negotiations: Congress Reaches Agreement Watch Video

House Republicans agreed to the up-or-down vote Tuesday evening, despite earlier talk of trying to amend the Senate bill with more spending cuts before taking a vote. The bill delays for two months tough decisions about automatic spending cuts that were set to kick in Wednesday.

A majority of the Republicans in the GOP-majority House voted against the fiscal cliff deal. About twice as many Democrats voted in favor of the deal compared to Republicans. One hundred fifty-one Republicans joined 16 Democrats to vote against the deal, while 172 Democrats carried the vote along with 85 Republicans.

The Senate passed the same bill by an 89-8 vote in the wee hours of New Year's Day. If House Republicans had tweaked the legislation, there would have been no clear path for its return to the Senate before a new Congress is sworn in Thursday.

The vote split Republican leaders in the House. House Speaker John Boehner, R-Ohio, voted yes, and so did the GOP's 2012 vice presidential candidate, Rep. Paul Ryan, R-Wis.

But House Majority Leader Eric Cantor, R-Va., the No. 2 Republican in the House, voted no. It was his opposition that had made passage of the bill seem unlikely earlier in the day.

The deal does little to address the nation's long-term debt woes and does not entirely solve the problem of the "fiscal cliff."

Indeed, the last-minute compromise -- far short from a so-called grand bargain on deficit reduction -- sets up a new showdown on the same spending cuts in two months amplified by a brewing fight on how to raise the debt ceiling beyond $16.4 trillion. That new fiscal battle has the potential to eclipse the "fiscal cliff" in short order.

"Now the focus turns to spending," said Boehner in a statement after the vote. "The American people re-elected a Republican majority in the House, and we will use it in 2013 to hold the president accountable for the 'balanced' approach he promised, meaning significant spending cuts and reforms to the entitlement programs that are driving our country deeper and deeper into debt."

Republicans hope that allowing the fiscal cliff compromise, which raised taxes without an equal amount of spending cuts, will settle the issue of tax rates for the coming debates on spending.

BCA to source for workers from Sri Lanka, Philippines

SINGAPORE: Sri Lanka and the Philippines have been identified as new source countries for construction workers.

The Building and Construction Authority (BCA) told MediaCorp that two test centres will be set up in Sri Lanka.

Approval is also being sought from the Philippine authorities to establish test centres there.

The BCA hopes to bring in skilled construction workers from Sri Lanka and Philippines to boost supply and diversify the source for foreign labour.

Demand for foreign construction workers is expected to remain strong in the years ahead.

The government is ramping up infrastructure development such as expanding the rail network and building more flats and health-care facilities.

In a recent report, the National Population and Talent Division expects the demand for foreign construction workers on low-skilled work permit holders to increase from some 250,000 in 2011 to about 280,000 in the next two to three years.

The main sources of foreign construction workers in Singapore are from China, India and Bangladesh.

The authorities want to be less reliant on these countries and have identified Sri Lanka and the Philippines as viable options.

Mr Neo Choon Keong, who is the Group Director of Manpower and Strategies Policy at the Building and Construction Authority, said: "What we are seeing now is that the major sources like China, India, because of the fast development the number of workers is actually coming down over time, because there are plenty of jobs there.

"So for resilience perspective, we are working with the industry to open up new sources to locate skilled workers. Notwithstanding our efforts to reduce the numbers of foreign workers overall through the adoption of technology as well as better building designs."

The BCA said most workers in Sri Lanka and Philippines speak English and this will help improve communication on the construction site.

Construction workers who want to work in Singapore have to go through a rigorous training regime in their country.

They have to stay in the training centre and undergo a full-time programme lasting between three and six months.

Only seven out of 10 of these workers would eventually pass the test.

After the training, potential workers have to go through a five hour practical test on essential craft skills as well as a one hour theory test on trade knowledge.

Currently, there are 26 overseas testing centres in China, India, Bangladesh, Thailand and Myanmar.

Potential workers can choose to be tested in 29 construction skills.

Construction company Progressive Builders will be operating one of the two new test centres in Sri Lanka.

Its managing director Ng Yek Meng said for a start, workers will be tested in 12 construction skills such as steel reinforcement work, tiling and plastering.

He said these tests are to ensure workers coming to Singapore are of a certain standard and quality, and could in turn help raise productivity.

Mr Ng said: "Some of the workers, especially if they come from agriculture, don't even know how to operate certain equipment. The test is quite stringent not only in Sri Lanka but for all source countries. Whoever can pass the test, I think they are of a certain quality. So this is how we can sieve the good ones and the bad ones."

The test centres in Sri Lanka are expected to be operational in six months' time.

Besides bringing in better quality construction foreign workers, the BCA also has a comprehensive training framework to continuously upgrade them.

Some 12,000 foreign construction foreign workers have upgraded their skills through these various programmes.

Why I still love the Nexus 7

There's something about the holidays and the cold January that often follows in the Northeast that makes me want to curl up on the couch with a good book -- or in this day and age, a book on my e-reader or
tablet.

The
Nexus 7 debuted more than six months ago at Google's annual developer conference, but I am still a big fan of the device. And I have no trouble recommending it to tablet buyers.

In this edition of Ask Maggie, I explain why the Nexus 7 is still a good device at a decent price. One Ask Maggie reader is tired of squinting to read books on his smartphone, but he's troubled by the $200 price tag. Meanwhile, the second reader is debating whether to get the smaller 7-inch Nexus 7 mini-tablet or a bigger
Android tablet from Samsung.

Nexus 7 or e-reader?

Dear Maggie,
I am debating whether I should get the Nexus 7 or not. The primary reason is the fact that I read books from the Google Play Store on my Razr Maxx right now and would love to have a larger screen that is portable. But at this point I have managed to read on the smaller screen, and I'm not sure spending $200 for a bigger screen makes sense. I've looked at e-readers, but if I am going to spend any money on a new device, I'd like to have the ability to do other things in addition to reading books. It would be great to be able to read email, play games, watch movies, etc.

I don't like using my computer for Web browsing and reading, but my smartphone seems too small. Do you think I should spend the $200 to get another device like the Nexus 7?

Based on your experiences, what would you recommend?

Thanks,
MagicWithMeaning

Dear MagicWithMeaning,
I hear you. I also think that a smartphone is too small for reading, although I know some people who don't mind it. My colleague Stephen Shankland read the entire Steve Jobs biography on his smartphone in a single night and wrote an amazing review of the book when it came out. I am afraid if I had attempted the same thing, I would have gone blind. And I probably would have only gotten through a quarter of the book in a night.

There's an array of options when it comes to choosing a device for reading e-books.

Sarah Tew/CNET)

At any rate, as I said, some people really don't mind the smaller size of a smartphone. And since you can magnify the text, it's certainly doable. But it sounds like you don't find this situation ideal. And I'm with you.

I think the Nexus 7 is a terrific step up, and I highly recommend it to readers. It's very light, and the size is perfect. It's about the size of a typical paperback book and can easily be held with one hand. It fits nicely into a pocket or purse, so it's portable if you read while commuting or traveling.

And since it comes with the full Android OS, you can access just about anything from the Google Play store. I mention this because other tablets of a similar size, such as the Kindle Fire, offer only a limited catalog of books, games, and movies. Whatever is available via Amazon is what's available on the Kindle Fire. This is great if you are already using that ecosystem to purchase your books and other media. But it sounds like you are already getting books and other stuff via the Google Play store, so it makes sense for you to continue using that ecosystem.

I know the $200 price tag isn't cheap. But it's a good deal considering how much other gadgets cost. Even full-priced smartphones are $400 to $500 more than the Wi-Fi only Nexus 7 tablet.

If you're looking to do more with your device, then the mini-tablet is a good pick over something like a dedicated e-reader. But the one thing I like about e-readers is the e-ink display. I think that display is a bit easier on my eyes, and I can sit and read a book for much longer than if I am using a device like the Nexus 7, which has a backlit screen.

But that is just my personal preference. I know plenty of people who don't have a problem with backlit screens. And in fact, it makes it easier to read in the dark, something that can't be done with an e-ink device.

I agree that if you're looking for the most bang for your buck, you might as well get a tablet that will give you a full browser and access to entire an app store instead of a limited-use e-reader.

Samsung Galaxy Note 2

Josh Miller/CNET)

But there is one option that you didn't mention in your question. What about getting a "phablet?" If you are able to upgrade to a new smartphone soon you may want to consider something like the Galaxy Note 2. With a 5.5-inch display, it's between the size of most Android smartphones and the 7-inch Nexus 7 tablet. It costs about $300 from carriers such as AT&T with a two-year contract. This is more than other smartphones such as the Galaxy S3. And it's more than the Nexus 7. But if you did need a new smartphone and you didn't want to buy a separate device, it might be a good compromise.

If a new smartphone isn't in the cards for you right now and you really are teetering on the edge of whether to buy the Nexus 7 or not, I'd say go for it. I know that $200 is nothing to sneeze at for many people. But when compared to larger tablets and full-priced smartphones, it's a bargain.

If you are strapped for cash, you could always wait a little longer to see if Google announces a cheaper version of the device. There are some reports from Asia that Google may be readying a $99 mini-tablet.

I hope this advice was helpful. And good luck!

Nexus 7 vs. Galaxy Tab 2 10.1

Dear Maggie,
I'm getting my first Android tablet, but I'm on a strict budget. I have wanted the Nexus 7 for a while, but found a great deal ($270) for a refurbished Samsung Galaxy Tab 2 10.1. Which is better?

Thanks,
TEP

Dear TEP,
The answer to your question really depends on which screen size you like better. The Galaxy Tab 2 has a bigger 10-inch screen, while the Nexus 7 has the smaller 7-inch screen. Personally, I prefer the smaller screen to the bigger one. The smaller tablets are easier to stick in a pocket, bag, or purse. And you can hold it with one hand. I use the Nexus 7 for reading, and I find that it's fairly light and easy to hold with one hand.

Samsung Galaxy Tab 2 10.1

Samsung)

That said, the Galaxy Tab 2 10.1 is a fine device. And it has gotten decent marks from CNET and other tech reviewers. If you like that size device and you want an Android tablet, then that is a good device to consider. And the price certainly sounds right.

But if the size is really a toss-up, and you could go either way, then I would still choose the Nexus 7. CNET rated it as one of the best Android tablets on the market. And at $200 brand new, it's still $70 less than the refurbished Galaxy Tab 2 that you have found.

  Happy Trails

  Photograph by Alex Cherney, TWAN

  Amateur astronomer Alex Cherney captured these star trails as they blazed above Lake Tyrrell, a salt lake in Victoria, Australia in October 2011 and posted to The World At Night website December 25, 2012.

  (See pictures of another Australian salt lake, Lake Eyre.)

  The sprawling Japanese capital Tokyo looks like a funky computer chip in this image taken by Germany's Earth-observing satellite TerraSAR-X and released December 20.

  Launched in 2007, the satellite's radar sensors map Earth from 319 miles (514 kilometers) up in a near-polar orbit.

  Extreme View

  NASA's Solar Dynamics Observatory snapped this extreme ultraviolet view of an active region on the sun as it rotated into view from December 16 to December 18. Ultraviolet light makes it easier to trace the whorls and loops created by superheated gas, or plasma, and the sun's magnetic field lines.

  Active solar regions such as this create space weather that, when aimed at Earth, can disrupt satellite communications and electronics. (See more pictures of solar activity and space weather.)

  This image of the unlit side of Saturn's S rings, released December 24, was taken with visible light by NASA's Cassini spacecraft.

  The shadow of Saturn's innermost major moon, Mimas, is visible as a black oval south of the rings' shadow. For those with completely dust-free computer monitors, Janus, another Saturnian moon, is visible as a tiny white speck above the planet's north pole. (Learn about Saturn's major moons.)

  A River Runs Through It

  The European Space Agency released this picture—taken by Japan's satellite ALOS—of Italy's longest river on December 14.

  The Po river and its surrounding fields divide Italy into its northern and southern regions. The Japanese used ALOS, which they lost contact with in late April 2011, to generate precise land maps, monitor disasters, and conduct resource surveys. (Read an excerpt from National Geographic magazine about the Po river.)

  Glacial "Broccoli"

  The Moshniy glacier, located on the Russian archipelago Novaya Zemlya in the Arctic Ocean, calves chunks of ice and debris into a pattern reminiscent of broccoli in an image released December 20.

  Novaya Zemlya was a sensitive military area during the Cold War, and was also the site of the most powerful nuclear device ever detonated. The energy released by the 50-megaton "Tsar" bomb was ten times that of all the explosions set off during World War II.
