C. African Republic leader faces rebel threat






DAMARA, Central African Republic (AP) — More than 30 truckloads of troops from Chad line the two-lane highway just outside of Damara, supporting Central African Republic government forces who want to block a new rebel coalition from reaching the capital.


In a display of force, the turbaned fighters hold their rocket-propelled grenades and other weapons they threaten to use if the rebels seeking to oust President Francois Bozize push this far south.






Gen. Jean Felix Akaga, who heads the regional force known as FOMAC, says a push on Damara, just 75 kilometers (45 miles) north of the capital, would be “a declaration of war” on the 10 Central African states.


“For us, Damara is the red line that the rebels cannot cross,” Akaga said Wednesday. “If they attack Damara, we will attack.”


The United Nations called for talks between the government and rebels and the Security Council scheduled closed consultations on the Central African Republic on Thursday afternoon.


The multinational force brought journalists up to Damara, where they touted the strength of the Chadian troops, who along with forces from Republic of Congo and Gabon are helping to stabilize the area.


The rebels, though, appear to be holding their positions after taking a string of towns including Sibut, which is 70 miles (112 kilometers) further north from Damara.


Back in 2003, troops under Bozize seized the capital amid volleys of machine-gun and mortar fire, and he then dissolved the constitution and parliament. Now a decade later it is Bozize who himself could be ousted from power.


On Wednesday, he announced through a decree read on state radio that he was dismissing his son, Francis, as defense minister. Chief of Staff Guillaume Lapo also was being replaced.


The president already has promised to form a coalition government with rebels and to negotiate without conditions. It’s a sign of how seriously Bozize is threatened by the rebel groups who call themselves Seleka, which means alliance in the Sango language.


Bozize says there’s one point not up for negotiation: he does not intend to leave office before his term ends in 2016.


“We can’t destroy the country. I don’t think that a transition is a good solution for the rebels, for Central African Republic or for the international community,” said Cyriaque Gonda, a spokesman for the political coalition behind Bozize.


But mediators for the government and others note the rebels — an alphabet soup of acronyms in French, UFDR, CPJP, FDPC and CPSK — want Bozize gone. And that’s the only issue the disparate group seems unified on. Seleka is a shaky alliance that lumps together former enemies.


In September 2011, fighting between the CPJP and the UFDR left at least 50 people dead in the town of Bria and more than 700 homes destroyed.


“Even if they show unity in the military action, we know that they are politically very disunited, the only thing that holds them together is the opposition to the current president,” said Roland Marchal, a Paris-based expert on Central African Republic. “If they take control of the capital I think that divisions would appear quickly.”


Gonda, who has negotiated on behalf of the government with the rebels, says some of them couldn’t even accept sitting together as recently as 2008.


Meanwhile, in some parts of the capital, Bangui, a city of 700,000, life continued as normal, while in others the military buildup was evident.


Trucks full of soldiers bounced on rutted roads dotted with shacks where people can charge mobile phones. Police officers stopped vehicles at intersections. Troops from neighboring nations have arrived including about 120 soldiers each from Republic of Congo and Gabon to help stabilize the area between rebel and the government forces.


In the Bimbo neighborhood, traders went about their business, selling everything from leafy greens to meat at roadside stands.


“We don’t support what the rebels are doing,” said banana farmer Narcisse Ngo, as a young boy played nearby with a monkey corpse for sale along with other meat. “They should be at the table negotiating without weapons. We are all Central Africans.”


Bozize, who seized power while the democratically elected president was traveling outside the country, managed to win elections in 2005 but in the years since he has faced multiple low-level rebellions that have shattered security across the northern part of this large but desperately poor country.


He won the 2011 election with more than 64 percent of the vote, though the United States said the voting was “widely viewed as severely flawed.” The U.S. evacuated its diplomats from Bangui last week.


The most prominent among the rebel groups in Seleka is the UFDR, or Union of Democratic Forces for Unity.


Human Rights Watch, which has documented abuses by both government forces and rebel groups operating in the country’s north, says the UFDR rebellion “has its roots in the deep marginalization of northeastern CAR, which is virtually cut off from the rest of the country and is almost completely undeveloped.”


The rebels, though, also have included some of Bozize’s former fighters who helped bring him to power in 2003 but later accused him of failing to properly pay them, among other grievances, Human Rights Watch says.


For the people now caught in the middle, they want life to return to normal.


“Everyone is suffering here — we have nothing to eat,” said Daniel Ngakou, 55, as he watched the Chadian troops patrol his hometown of Damara. “The women are searching in the bush all day for food. We just don’t know what will happen.”


The United Nations called on the government and the rebels Wednesday to focus on dialogue that can avert violence and lead to a peaceful resolution of the conflict and respect for the 2008 Libreville Comprehensive Peace Agreement. That deal was signed by the government and three major rebel groups.


U.N. spokesman Martin Nesirky reiterated the U.N. Security Council’s call last week for all parties to refrain from any acts of violence against civilians, respect human rights and seek a peaceful solution.


“We welcome regional efforts to seek a political solution and reinforce security,” Nesirky told reporters at U.N. headquarters in New York.


While the United Nations has temporarily withdrawn its staff from Central African Republic, Nesirky said the world body remains engaged in efforts to resolve the crisis.


He said U.N. special representative Margaret Vogt “has remained in close dialogue with the key parties in the Central African Republic and the region and has offered support to political negotiations,” he said.

The Most and Least Influential Social Media Celebs






While he isn’t currently available for promotional work, businesses would have the most success on social media with President Barack Obama endorsing their goods and services, new research shows.


A study by social marketing platform SocialToaster revealed that Obama is considered the most influential celebrity on social media. Justin Bieber, Lady Gaga, Ashton Kutcher and Anderson Cooper followed the president on the rankings of social influencers.






On the flip side, the research found that former Republican presidential nominee Mitt Romney was the least influential celebrity on social media, finishing just below Madonna, Kanye West and Sean Hannity.


While celebrities might be influential on social media in some aspects, it’s those closest to us who make the largest impact when it comes to the important issues. Nearly all of the social media users surveyed agreed that a social media post from a close friend or family member was most likely to influence them on important subjects, with politicians and athletes the least likely to influence them.


“While it was no surprise that in this election year Barack Obama would be ranked the most influential person in social media, it was surprising to us that Justin Bieber and Lady Gaga would beat Madonna and Kanye West,” said Brian Razzaque, CEO of SocialToaster. “We were also surprised to see that friends had more pull than family when it came to influencing the sharing of social media content.”


Regardless of whom it comes from, there are some posts that will quickly result in an unfollowing, the study discovered. Nearly three-quarters of those surveyed said a racist post would cause them to immediately unfollow someone on social media. Other types of posts that result in a loss of followers include sexism, pornography, repetitive, overly personal posts and those that use poor grammar.


The researcher was based on surveys of 3,000 SocialToaster Super Fans, which consist of social media experts and professionals, many of whom work with some of the nation’s leading brands. The experts range from those who work in the entertainment industry who represent numerous television shows and movies to those who work in professional sports, including the Baltimore Ravens and the Detroit Pistons.

Women Lose Half Their Weight: How They Did It






At 25 years old and 288 pounds, Ashley Donahoo was depressed.


“I was unhappy with my job, I was unhappy with the direction my life was going, and I had a hard time enjoying the little things that my kids wanted to do,” the 27-year-old mother of two from Pace, Fla., said. “My health was failing. My doctor told me that he didn’t think I was going to make it to 30 if I kept on [this way]. … It kept getting worse and worse.”






Donahoo was concerned, but it was her faithful husband, David, who pushed her on a path to health, starting with a walk around the block.


“His heart was breaking for me,” she said. “And he saw how unhappy I was, and he came to me and said, ‘We’re going to go for a walk.’  And I was, like, ‘No, we’re not.’”


Her husband won that battle, and on the walk, she started thinking about her own choices and future.


“The realization hit me that I made this choice.  I made this choice to get where I am right now.  So I’m going to start making a different choice,” she said.   ”I put my health and myself on back burner, and I think … it had all caught up to me.”

Like Donahoo, Caroline Jhingory reached a similar eye-opening realization about her weight.


“I looked in the mirror one day and just realized I didn’t recognize the person that was staring back at me,” said Jhingory, 32, of Washington, D.C.


Jhingory’s struggles with her weight began early. At age 8, she weighed 120 pounds. Taunted by her peers, Jhingory was enrolled in a medical weight loss program, but it didn’t work because she would sneak junk food like candy bars.


“I found a way to be a food hustler and get whatever food I wanted,” she said. “Not only did I spend two decades of my life morbidly obese. I spent two decades of my life being taunted and teased in every environment. I never went to prom. I never had dates. I couldn’t ride a roller coaster because the safety bar wouldn’t go over my stomach.”


Jhingory remained heavy until college, when she tipped the scales at 303 pounds and started feeling self-conscious in her new environment.


“I felt like I had a moment when all these difficult experiences were a huge pause button on my life. I finally said to myself, ‘I’m tired of this. I want to have a normal life.’”


Jhingory started walking everywhere. Then, she took up a daily cardio regimen to shed the weight, and she rid her pantry of tempting snack foods she once binged on. Now 149 pounds, she has reclaimed her shape and kept off the weight.


Jhingory’s amazing transformation, along with Donahoo’s and other weight-loss success stories, were spotlighted in the “Half Their Size” feature in the latest issue of People magazine.


RELATED: Is Being Overweight Really Bad For You?


Donahoo cut out the late-night binges that brought her down and, thanks to her strong support system, lost 137 pounds. She credited her weight loss success to tracking her food and exercise on livestrong.com and running. She has run two 5Ks.


Leah Fernandez of Atlanta found herself at 251 pounds after two pregnancies. The baby weight stuck and she tended to eat emotionally.


“I wanted the food,” she said. “It made me feel good, and so I ate it.”


But it was the motivation to be there for her children that helped her turn it all around.


“Thinking about going out to the park with my kids felt like work to me, you know?  And at some point I realized that’s ridiculous. Not only am I cheating myself but I’m cheating my kids of me,” she said.


Fernandez turned to Jenny Craig in March 2011 and hasn’t looked back. Since then, she has lost half her weight by staying active with her kids and incorporating walking into her lifestyle.


“I’m getting my groove back.  Leah’s getting her groove back,” she said.

Markets rally on US fiscal deal







Continue reading the main story






Global stock markets have rallied after a short-term deal to stave off the US “fiscal cliff” was reached.


The Dow Jones gained 1.8% at the open on Wall Street, while European shares were up by more than 2% for the day.


Failure to agree a deal would have triggered spending cuts and tax rises worth $ 600bn (£370bn), expected to throw the US back into recession.


However, the deal has only postponed by two months negotiations over spending cuts and the government debt ceiling.


Just before the New Year, the US Treasury Secretary Tim Geithner indicated that the federal government would run up against the debt ceiling – a legal cap on its total borrowing set by Congress – by the end of February.


The fiscal cliff deal does not include an increase in the debt ceiling. It also postpones by two months steep automatic spending cuts to federal government spending on things like defence and education.


The fiscal cliff measures – immediate tax rises worth $ 536bn, as well as spending cuts of $ 109bn from benefit payments and domestic and military programmes – were due to come into effect automatically at midnight on Monday.


Tax rises


The deal has averted most of these measures, including:

This week’s deal lifts the risk of an accidental recession – at least for a while”



End Quote



  • making permanent tax cuts dating back to George W Bush’s presidency, for individuals earning less than $ 400,000

  • postponing the $ 65bn of automatic spending cuts for two months

  • keeping benefits available for the long-term unemployed, worth $ 26bn, for another year

  • postponing for another year an $ 11bn cut in Medicare payments

However, the deal did also allow some tax rises to go ahead, namely:


  • the expiry of a payroll tax holiday, expected to raise $ 95bn in additional annual revenue

  • allowing the Bush-era income tax cuts for individuals earning over $ 400,000 to come to an end, with the top rate increasing from 35% to 40%

  • higher taxes on dividend income, capital gains and inheritance for these same top earners

  • phasing out certain income tax deductions for individuals earning more than $ 200,000

The increase in payroll taxes is likely to be the most significant of these measures, in terms of how much it raises in revenue for the government, the number of taxpayers affected, and its impact on the economy.


Payroll tax is paid by all employees. The tax holiday – which cut the rate from 6.2% to 4.2% – was introduced by President Barack Obama three years ago to help stimulate the lethargic economy by putting more money in the pockets of ordinary American workers, who were most likely to go out and spend it.

The battle [over spending cuts] has just been shoved two months down the road”



End Quote



Economists suggest that its expiry is likely to have the biggest impact on spending – particularly consumer spending – in the US.


Jan Hatzius, chief economist at Goldman Sachs, has said it would reduce US economy growth by 0.6%.


‘Disappointment’


The deal has postponed the hardest decisions that Republican and Democratic politicians must still reach agreement on – over spending cuts and the debt ceiling.


Both issues will need to be addressed at the end of February, with Republicans likely to demand deep cuts, particularly to entitlement programmes such as social security, in return for an increase in the legal cap on government borrowing.


President Obama’s Democrats would prefer to reduce the government’s deficit via further tax rises.


“In the most immediate sense, they took their feet of the cliff, but once again they have taken the hard work and pushed it down the street,” said Daniel Costello, a US economics commentator.


Continue reading the main story

Fiscal cliff explained


  • On 1 January 2013, tax increases and huge spending cuts were due to come into force – the so-called fiscal cliff

  • The deadline was put in place in 2011 to force the president and Congress to agree ways to save money over the next 10 years

  • The fear was that raising taxes while massively cutting spending would have huge impact on households and businesses

  • Experts believed it could have pushed the US into recession, and had a global impact on growth

  • A deal has been reached delaying some of the tax rises and all of the spending cuts by at least two months


“It’s a huge disappointment. The Republicans deeply wanted spending cuts. Their long-term goal is to finally start chipping away at some of the entitlement spending [on welfare payments] that is just getting out of control.”


Entitlement payments are expected to rise sharply in the coming decades as the post-World War II baby-boom generation retires and enters old age, entailing more government-funded medical care.


“Two-thirds of all federal spending comes from entitlement spending – that means when you wake up in the morning, two-thirds of the money is already spent. By 2020, that goes up to 90%.”


When President Obama last faced off against the largely Republican-controlled Congress over the debt ceiling in 2011, negotiations went to the wire before agreement was reached to increase the ceiling from $ 14.3tn to $ 14.7tn.


Markets fell sharply at the time on fears that, legally barred from borrowing any more, the government might be forced to default on some of its payment obligations, with unknown but potentially significant legal consequences.


The political wrangling also prompted ratings agency Standard and Poor’s to deprive the US of its top AAA credit rating.


Temporary lift


Despite the deal’s shortcomings, markets took cheer from the fact that agreement had been reached on how to postpone and moderate the process of bringing the government’s overspending back under control.




Richard Hunter, Hargreaves Lansdown: “This points the market in the right direction”



The FTSE 100 index rose 145 points to 6,043 points, the first time it has been above the 6,000 level in 17 months, with mining shares leading the way.


The UK market was also boosted by a survey of production and new orders in the manufacturing sector, which showed activity at a 15-month high in December.


Shares worldwide had been hurt in November and December by fears that the US would not be able to reach any kind of agreement and would go off the cliff.


Analysts said the relief would not last.


Mike McCudden, head of derivatives at stockbroker Interactive Investor said: “There will no doubt be a few more twists and turns in the days ahead… but for now, investors have the concrete news they were hoping for.”


Joe Rundle, head of trading at ETX Capital, said: “Today’s bullish tone may continue as we head toward the weekend. but the euphoria will most certainly evaporate, as the deal voted through does not include raising the debt ceiling and longer-term budget cuts.


“It’s only a matter of time before market participants lose their buzz as US lawmakers will have to reconvene to address the remainder of unresolved issues.”

Israeli-Palestinian clashes erupt in West Bank






TAMOUN, West Bank (AP) — An arrest raid by undercover Israeli soldiers disguised as vegetable vendors ignited rare clashes in the northern West Bank on Tuesday, residents said, leaving at 10 Palestinians wounded.


Israeli army raids into Palestinian areas to seize activists and militants are fairly common. The raids are normally coordinated with Palestinian security forces, and suspects are usually apprehended without violence.






The clashes began early Tuesday after Israeli forces disguised as merchants in a vegetable truck arrested one man. Regular army forces then entered the town, prompting youths to hurl rocks to try to prevent more arrests.


Israeli forces fired tear gas, rubber bullets and live ammunition as youths set tires and bins on fire to block the passage of military vehicles. In several hours of clashes, dozens of masked youths hid behind makeshift barriers, hurling rocks and firebombs at soldiers.


Faris Bisharat, a resident of Tamoun, said 10 men were wounded, some by live fire. Bisharat said the wanted men belong to Islamic Jihad, a violent group sworn to Israel’s destruction. It wasn’t clear how many men Israeli forces sought to arrest. There were no immediate details on how seriously the 10 were hurt.


The Israeli military said it arrested a “terrorist affiliated with the Islamic Jihad terror group.” It said two soldiers were injured during the raid.


The fighting, which broke out in several parts of the town of some 8,000 people, were a rare, angry response. It was also unusual for Israeli forces to use live fire toward Palestinian demonstrators. Israel says it uses live fire only in extremely dangerous situations.

Apple testing new iPhone, iOS 7: report






(Reuters) – Apple Inc has started testing a new iPhone and the next version of its iOS software, news website The Next Web reported.


Apple shares were up 2.6 percent at $ 546.06 in premarket trading. The stock closed at $ 532.17 on the Nasdaq on Monday.






Application developers have found in their app usage logs references to a new iPhone identifier, iPhone 6.1, running iOS 7 operating system, the website reported. (http://r.reuters.com/fyd94t)


Apple‘s iPhone 5 bears the identifiers “iPhone 5.1″ and “iPhone 5.2″ and is powered by iOS 6 operating system.


Developer logs show that the app requests originate from an internet address on Apple’s Cupertino campus, suggesting that Apple engineers are testing compatibility for some of the popular apps, the website said.


“Although OS and device data can be faked, the unique IP footprint leading back to Apple’s Cupertino campus leads us to believe this is not one of those attempts,” the website said.


Apple launched iPhone 5 in September and it has been reported that the new iPhone will be released in the middle of 2013.

Could Trip to Mars Cause Alzheimer’s?






Space travel has always been portrayed as risky — no air or water, extreme temperatures — a place where even a small miscalculation can be fatal. It can also be hazardous to your brain health, particularly on a three-year-long mission to Mars, according to a study published this week in the scientific journal PLOS ONE.


The eight-year long study, conducted at the NASA Space Radiation Laboratory at Brookhaven National Laboratory on New York’s Long Island, found that the cosmic radiation on such a mission could accelerate the onset of Alzheimer’s disease.






NASA is working on sending astronauts to a passing asteroid in the 2020s, and talks of a trip to Mars in the 2030s. It would take three years, with current technology, to get there and back. Current spacecraft are not heavily shielded from the cosmic radiation crew members would encounter beyond Earth’s protective magnetic field.


Researchers used mice that were genetically engineered to be predisposed to Alzheimer’s disease. They exposed them to cosmic radiation that was simulated in the lab.


“Galactic cosmic radiation poses a significant threat to future astronauts,” said Dr. M. Kerry O’Banion, senior author and professor of neurobiology and anatomy at the University of Rochester Medical Center.


The study team wanted to see if radiation had the potential to accelerate Alzheimer’s in those who were genetically vulnerable. Mouse models have been used extensively in this type of research and the rate at which they develop the disease is well understood.


Scientists have long worried about the potential dangers of working and living in deep space. Cosmic radiation beyond low Earth orbit, researchers say, could lead to cancer, cardiovascular disease, even cataracts.


Radiation exposure can cause acute effects such as nausea, vomiting, fatigue, skin injury and changes to white blood cell counts and the immune system, according to the National Space Biomedical Research Institute. Longer-term radiation effects include damage to the eyes, gastrointestinal system, lungs and central nervous system.


On Earth, humans are protected by the planet’s atmosphere and magnetic field. Crew members on the International Space Station, at an altitude of 200 miles, are still within the magnetic sheath that surrounds us. The 24 Apollo astronauts who flew to the moon between 1969 and 1972 were not protected, but the longest missions lasted less than two weeks.


Once out of low orbit, astronauts are exposed to showers of different radioactive particles. Though engineers say they can protect themselves from the radiation associated with solar flares, so far, they cannot block other forms of cosmic radiation.


The longer astronauts are in deep space, the greater the exposure to this low-level radiation.


This is the first such study to explore effects of radiation on the nervous system, a phenomenon known as neurodegeneration, according to the authors.


“The possibility that radiation exposure in space may give rise to health problems such as cancer has long been recognized,” said O’Banion. “However, this study shows for the first time that exposure to radiation levels equivalent to a mission to Mars could produce cognitive problems and speed up changes in the brain that are associated with Alzheimer’s disease.”


O’Banion has spent the last 20 years studying Alzheimer’s disease.


He and his fellow researchers studied a form of radiation from so-called high-mass, high-charged particles, which come in various forms and fly through space at high speeds. Some come from distant stars that have exploded.


At Brookhaven, where a portion of the research was conducted, particle accelerators were able to recreate some of the radioactive particles found in space.


“It is extremely difficult from an engineering perspective to effectively shield against them,” said O’Banion. “One would have to essentially wrap a spacecraft in a six-foot block of lead or concrete.”


For the study, researchers used mice that had been engineered to have two human gene mutations associated with familial Alzheimer’s.


“Essentially, they were healthy mice with nasty genes,” said O’Banion. Under natural conditions, mice do not get the disease.


The mice were exposed to the radiation for several minutes. Six months later, researchers evaluated the exposure to see if it had any effect.


“A minute or two [of exposure] is like three years in human life,” O’Banion said. “It’s apples and oranges, a very different kind of exposure, but the total dose is equivalent to what an astronaut would receive [on a three-year Mars mission].”


Cosmic radiation is unlike anything on earth, according to O’Banion, similar only to what might be experienced in a nuclear accident.


“The big problem NASA faces is that shielding is not effective, and a spacecraft is not bulky enough to protect them over long periods of travel,” said O’Banion. “At least not now. In scenarios I have heard of sending people to Mars, they would then build an underground shelter on a long-term mission in order to protect them from radiation.”


While the research does not solve the problem of radiation in space or explain why humans develop Alzheimer’s disease, it is important, according to O’Banion.


“My own bias is this,” he said. “It’s just another example of how the environment can influence diseases. The mice had a genetic predisposition and you have added an environmental injury — an insult to their system. And now they show exacerbation of the disease.”


There may even be parallels with the development of the disease after brain injuries in football players, he said.


Jeff Chancellor, a scientist in radiation physics at the National Space Biomedical Research Institute, said the Rochester team’s study is solid.


“I know most of the authors and they are very well respected, and I have full confidence in their results,” he said. . “The main benefit of their research is being able to further enhance the field and perhaps provide justification for more research.”


“Any time you identify a mechanism for how a disease or a condition is induced, you further the ability to mitigate it,” he said. “It provides more tools for the researchers and for M.D.s … There are great benefits to all these studies.”

Relive the Paralympics’ Most Inspiring Moment of the Year






Back in July, we covered how social media would be critical to the success of the 2012 Paralympic Games. The Paralympics ended in September, but the International Paralympic Committee is still using the web to shine a light on unheralded athletes and tell stories of remarkable inspiration.


[More from Mashable: Watch the Scariest Skiing Lesson of All Time]






The committee revealed its top moment of 2012 in a video posted to YouTube on Sunday. It profiles Italian cyclist Alex Zanardi winning gold in London after losing his legs in an auto racing accident in 2001.
