Chad's 'mountains of hunger' as rendered by Turner

IT LOOKS like brushstrokes - it could almost be a Turner - but this is actually nature at its most dramatic. This snapshot from the European Space Agency's MERIS satellite shows the Tibesti mountains that straddle northern Chad and southern Libya - though a picture like this makes it easy to forget that borders exist.






The mountains, in blue and black at the centre, are a range of volcanoes. The grey and black peak in the bottom right is Emi Koussi, the tallest mountain in Chad at 3415 metres high. There aren't any recorded instances of any of the Tibesti volcanoes erupting, though Toussid‚, the black spot on the far left, does have a reputation for spewing gases and creating hot springs in its crater floor. The white regions are accumulations of carbonate salts, while the orange is desert.



For all their beauty from overhead, plant life is sparse on these mountains, known locally as the "Mountains of Hunger" because they feed so few people. The semi-nomadic Toubou people inhabit the region as salt miners and date and grain farmers, while some cheetahs, gazelles and sheep do roam the region.



Life expectancy in Chad is the lowest in the world at 48 years. An estimated 210,000 people are living with HIV and AIDS - 3.4 per cent of the population - while malaria, typhoid fever and hepatitis A are all major health problems. Thirty-four per cent of under-5s are underweight, and it has the worst maternal mortality rate of any nation. It's also home to 280,000 refugees from the Darfur conflict across the border in Sudan.



Rebellions frequently flare up in Chad, the most recent resulting in a four-year civil war that ended in 2010. Violent conflicts with Libya and Sudan have also plagued an already crippled country. Only from orbit do the borders not seem to matter.

Football: Sturridge hopes Mansfield goal is just the start






LIVERPOOL: Daniel Sturridge has insisted Liverpool fans have still to see the best of him despite taking only seven minutes to score on debut in Sunday's 2-1 FA Cup third round win at Mansfield.

The 23-year-old, signed from European champions and FA Cup holders Chelsea last week, got on the end of fellow England international Jonjo Shelvey's through-ball to give Liverpool an early lead at Field Mill.

But Sturridge - who last played a senior match in November - missed further chances before he was replaced by Luis Suarez, with the Uruguay forward making it 2-0 thanks to a controversial 59th minute goal that saw the ball hit his arm in the build-up.

Mansfield's Matt Green pulled a goal back 11 minutes from time to ensure a nervous finish for Premier League Liverpool.

"I haven't had much training," Sturridge told Monday's Liverpool Echo.

"I've only had three sessions with the lads and then a light session on Saturday before the game.

"I am lacking sharpness in front of goal. I missed a few chances but hopefully once I get my fitness those ones that I missed will go in.

"It was a great pass from Jonjo - the vision and the weight of the pass for the goal was perfect. He made it quite easy for me to take the shot first time.

"We haven't had much time to work on stuff but we were both on the same wavelength. We get on well on and off the field.

"All the lads have been great with me and they've made it easy for me to settle in over the past few days.

"I want to say thank you to them for making me feel so welcome. I look forward to playing with them for many years to come."

Ideo's David Kelley talks design, Steve Jobs



David Kelley on 60 Minutes

Design guru David Kelley tells Charlie Rose about one of Ideo's bright ideas: An iPhone application that allows children to receive calls from Sesame Street character Elmo about topics their parents select.

Meet one of the most innovative thinkers of our time. He is a man who has had an enormous impact on our everyday lives.


David Kelley is the founder of the Silicon Valley global design firm Ideo. His company has created thousands of breakthrough inventions, including the first computer mouse for Apple, the standup toothpaste tube, and a better Pringle for Procter & Gamble. Ideo may be the most influential product design company in the world.


Kelley was a longtime friend and colleague of Steve Jobs -- "He made Ideo," Kelley tells Rose -- and he is a pioneer in something known as "design thinking," an innovative approach that incorporates human behavior into design.


David Kelley: "The big thing about design thinking is it allows people to build on the ideas of others. Instead of just having that one thread, you think about it, I come up with an idea, and then somebody from somewhere else says, 'Oh that makes me think we should do this,' and then we could do that. And then you get to a place that you just can't get to in one mind."


If you follow David Kelley around Ideo, you can see how he has infused that thinking into the legendary Palo Alto firm he founded more than 20 years ago. Breakthrough ideas happen every day here.

Hagel Nomination Stirs Bipartisan Opposition













Two weeks before his inauguration, and with more "fiscal cliffs" on the horizon, President Obama is embracing a showdown with Congress over his pick to lead the Pentagon in his second term.


Obama will nominate former Republican Sen. Chuck Hagel to be the next Secretary of Defense at a formal White House announcement later today, administration officials said.


The president will name counterterrorism advisor John Brennan as the new CIA director to replace David Petraeus, rounding out an overhaul of his national security team.


Obama tapped Sen. John Kerry of Massachusetts last month to become the next Secretary of State.


Hagel is in many ways an ideal pick for Obama, giving nod to bipartisanship while appointing someone with a demonstrated commitment to veterans of Iraq and Afghanistan and to retooling and economizing the Pentagon bureaucracy for the future.


But the nomination of Hagel to replace outgoing Defense Secretary Leon Panetta is also politically charged, expected to trigger a brutal confirmation fight in the Senate, where a bipartisan group of critics has already lined up against the pick.


"This is an in your face nomination by the president to all of us who are supportive of Israel," Sen. Lindsey Graham, R-S.C., told CNN on Sunday. "I don't know what his management experience is regarding the Pentagon -- little, if any, so I think it's an incredibly controversial choice."










The criticism stems from Hagel's controversial past statements on foreign policy, including a 2008 reference to Israel's U.S. supporters as "the Jewish lobby" and public encouragement of negotiations between the United States, Israel and Hamas, a Palestinian group the State Department classifies as terrorists.


"Hagel has consistently been against economic sanctions to try to change the behavior of the Islamist regime, the radical regime in Tehran, which is the only way to do it, short of war," Sen. Joe Lieberman, I-Conn., said last month.


The Nebraska Republican has also drawn fire for his outspoken opposition to the 2003 U.S.-led war in Iraq and the subsequent troop "surge" ordered by then-President George W. Bush in 2007, which has been credited with helping bring the war to a close.


On the left, gay rights groups have protested Hagel for comments he made in 1998 disparaging then-President Bill Clinton's nominee for U.S. Ambassador to Luxembourg James Hormel as "openly, aggressively gay." Hagel has since apologized for the remark as "insensitive."


Top Senate Democrats tell ABC News there is no guarantee Hagel will win confirmation and that, as of right now, there are enough Democratic Senators with serious concerns about Hagel to put him below 50 votes.


But that could change, with many top lawmakers publicly vowing to withhold final judgment until Hagel has an opportunity to answer his critics during confirmation hearings. No senator has yet publicly vowed to filibuster the Hagel nomination.


Hagel is a decorated Vietnam veteran and businessman who served in the senate from 1997 to 2009. After having sat on that chamber's Foreign Relations and Intelligence committees, he has in recent years gathered praise from current and former diplomats for his work on Obama's Intelligence Advisory Board as well as the policy board of current Defense Secretary Leon Panetta.


"Chuck Hagel is a tremendous patriot and statesman, served incredibly in Vietnam, served this country as a United States senator. He hasn't had a chance to speak for himself. And so why all the prejudging?" said Sen. Heidi Heitkamp, D-N.D., on "This Week."


"In America, you give everybody a chance to speak for themselves and then we'll decide," she said.


The top Senate Republican echoed that sentiment. "I'm going to wait and see how the hearings go and see whether Chuck's views square with the job he would be nominated to do," Senate Minority Leader Mitch McConnell of Kentucky said.

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 Karaƛ 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.

Obama considers arms sales restrictions: report






WASHINGTON: The administration of President Barack Obama is considering a broad array of measures to curb the nation's gun violence, including more than just a reinstatement of a ban on assault weapons and high-capacity ammunition, The Washington Post reported on Sunday.

Citing multiple people involved in the administration's discussions, the newspaper said a working group led by Vice President Joe Biden is seriously considering several measures: universal background checks for firearm buyers, tracking the movement and sale of weapons through a national database, strengthening mental health checks, and stiffening penalties for carrying guns near schools or giving them to minors.

To push these measures through Congress, the White House is developing strategies to work around the National Rifle Association (NRA), the report said.

According to the paper, they could include rallying support from Wal-Mart and other gun retailers as well as regular contact with advisers to New York Mayor Michael Bloomberg, an outspoken gun-control advocate.

The proposals are a response to last month's tragedy in Newtown, Connecticut, the site of one of the worst school shootings in US history.

On December 14, 20-year-old Adam Lanza killed his mother in their Newtown home before embarking on a shooting spree at a local elementary school.

He blasted his way into Sandy Hook Elementary School and shot dead 20 six- and seven-year-old children and six adults with a military-style assault rifle before taking his own life with a handgun as police closed in.

However, the NRA, the most powerful gun lobby in the United States, stands firm against any additional restraints on firearms and ammunition sales -- despite a national outcry in the wake of the Sandy Hook school massacre.

Dropped call: Mobile biggies conspicuous by absence at CES

Sarah Tew/CNET)


LAS VEGAS -- Mobile is supposed to be a hot category in tech, right? You'd never know it looking at the announcements that are slated to start pouring in this week.


Many of the major companies in the mobile industry have opted to skip or limit their presence at this year's Consumer Electronics Show, which kicks off tomorrow for the media before officially opening on Tuesday. The announcements that do come out will emerge from lower-tier companies hoping to make more of a name for themselves and their products.


The dearth of wireless-related news at a time when the tech world is going increasingly mobile underscores the dilemmas that a show like
CES faces: too many competing conferences, more companies opting to hold their own events, and unfortunate timing after a large wave of product announcements ahead of the holidays. As a result, don't expect to have your mind blown with the mobile announcements coming out this week.



"There aren't really high expectations for lots of big news coming out from CES," said Daniel Hays, a consultant for PricewaterhouseCoopers. "CES is an increasingly crowded forum to get your message out. That probably causes some vendors to hold back in making major announcements."


Apple and Google, authors of the two largest mobile operating systems in the world, have long had minimal to zero presence at CES. Microsoft, which made its big push for Windows Phone 8 in October, held its last keynote address here a year ago. Research In Motion, the other significant mobile operating system, will formally unveil its next-generation BlackBerry 10 operating system at its own event later this month.


Samsung has long had one of the largest presences at CES, but it won't have much in terms of smartphone or
tablet announcements, having already heavily invested in a campaign for its Galaxy Note 2 and the continued run of its Galaxy S III late last year. The company also pulled out of the
CTIA Wireless show last year, opting instead to launch its flagship phone at its own event, much like Apple.


Other traditional mobile heavy hitters, including Google's Motorola Mobility, Nokia, and HTC, won't have much to say as well.


The carriers, which in recent years have stepped up their presence at CES, are expected to remain quiet this year. Verizon CEO Lowell McAdam has a keynote address scheduled for tomorrow, but the company isn't expected to make any major wireless announcements, a far cry from the splashy launch of its 4G LTE network two years ago. AT&T, which holds its own developer summit separately from CES but usually offers some mobile news, is likewise expected to remain mum.


T-Mobile USA will hold a press conference and likely talk about its network plans and pending deal with MetroPCS, although actual phone announcements could be slim. Sprint Nextel, still working through its own pending merger with SoftBank, doesn't have any formal event scheduled.

Mobile World Congress around the corner


Mobile World Congress, based in Barcelona, has always been a major force. And with everything going more mobile, the show has grown even more in prominence and influence over the years. The U.S. carriers, which traditionally opted to skip MWC, are increasingly taking part in that show.


Likewise, a lot of major smartphone and tablet announcements are getting made there, rather than at CES. Asus, for instance, cancelled its press conference at CES, opting to debut its mobile products at MWC in February instead.


While Google isn't so high on CES, it has had a large presence at MWC over the past few years, including large booths complete with a slide, an array of demonstration booths, and toy claw machine giving away stuffed Android dolls.


MWC's legacy in mobile gives it an advantage over CES, which has traditionally been about televisions, PCs, and other random gadgets. The transition has been bumpy.


"It's all about your audience. CES has historically drawn an audience primarily focused on retailers. Increasingly, that audience are not just at CES; they're at other influential shows like MWC," Hays said.


CES is making the shift. Mobile chipset companies, for instance, make up some of the early announcements for the show. Tonight, Nvidia will kick things off with its own press event, unveiling its newest Tegra processor.


Meanwhile, Paul Jacobs, CEO of mobile chipmaker Qualcomm, takes over tomorrow's end-of-day keynote slot long occupied by Microsoft and its CEO, Steve Ballmer, another illustration of the shift from PC to mobile.

Opportunities for the second-tier companies


With a Samsung or Motorola out of the picture, that gives companies eager for some attention a chance to shine.


Sony is one of the few companies expected to announce a smartphone or two, and details have already begun leaking out.


Huawei and ZTE, two Chinese vendors eager to stake a larger claim of the U.S. market, are also expected to unveil smartphones at CES. Both are known primarily for low- and mid-tier smartphones and tablets, but the companies want to change that.


ZTE is expected to unveil a high-end flagship smartphone, the Grand S, at CES. It's still unclear whether it will actually sell in the U.S. though.


ZTE could be making a big splash at CES this year.

Huawei, meanwhile, is expected to go big with the Ascend Mate, a large phone with a 6.1-inch display that falls into a category many call "phablet," most notably led by the Galaxy Note franchise by Samsung.


Whether these products ever end up in the consumers' hands is still up in the air. But with some of better-known companies opting to save their ammunition for later, the companies presenting now will at least get heard.


"CES is still an extremely powerful platform for announcing new products and positioning yourself as a leader in the mobile space," Hays said.

Gun Show Near Newtown Goes on Despite Anger













A little more than 40 miles from Sandy Hook Elementary School, where last month 20 first graders and six staff members were massacred, gun dealers and collectors alike ignored calls to cancel a gun show, and gathered for business in Stamford, Conn.


Four other gun shows with an hour of Newtown, Conn., recently cancelled their events in the wake of the shootings, when 20-year-old Adam Lanza broke in to the elementary school with a semi-automatic assault rifle and three other guns.


The organizers in Stamford emphasized their show only displayed antique and collectible guns, not military style assault weapons like the one used by Lanza in Sandy Hook.


Still, Stamford Mayor Michael Pavia had called for the show to close its doors, calling it "insensitive" to hold so close to the murders.


Gun show participant Sandy Batchelor said he wasn't sure about whether going ahead with the show was "insensitive," but said the shooter should be blamed, not the weapons he used.


"I don't have a solid opinion on [whether it is insensitive]," Batchelor said. "I'm not for or against it. I would defend it by saying it wasnt the gun."


In nearby Waterbury, the community cancelled a show scheduled for this weekend.


"I felt that the timing of the gun show so close to that tragic event would be in bad taste," Waterbury Police Chief Chief Michael J. Gugliotti said.












National Rifle Association News Conference Interrupted by Protesters Watch Video





Gugliotti has halted permits for gun shows, saying he was concerned about firearms changing hands that might one day be used in a mass shooting.


Across the state line in White Plains, N.Y, Executive Rob Astorino also canceled a show, three years after ending a had that had been in place since the 1999 Columbine High School shooting in Colorado. He said he felt the show would be inappropriate now.


But across the country, farther away from Connecticut, attendance at gun shows is spiking, and some stores report they can hardly keep weapons on their shelves with some buyers fearful of that the federal government will soon increase restrictions on gun sales and possibly ban assault weapons altogether.


"We sold 50-some rifles in days," said Jonathan O'Connor, store manager of Gun Envy in Minnesota.


President Obama said after the Sandy Hook shooting that addressing gun violence would be one of his priorities and Rep. Nancy Pelosi, D-Calif., said she would introduce an assault weapons ban this month.


But it is not just traditional advocates of gun control that have said their need to be changes in gun laws since the horrific school shooting.


Republican Sen. Kay Bailey Hutchison of Texas and Virginia Sen. Mark Warner, a Democrat but a long-time opponent of gun control who like Hutchison has received an A rating from the NRA, have both come out in support of strengthening gun laws.


In Stamford, gun dealer Stuart English said participants at the gun show there are doing nothing wrong.


"I have to make a living. Life goes on," gun dealer Stuart English said.


ABC News asked English, what he thought about the mayor of Stamford calling the show "insensitive."


"He's wrong," English said. "This is a private thing he shouldn't be expressing his opinion on."
