U.K. Dash for Shale Gas a Test for Global Fracking

Thomas K. Grose in London

The starting gun has sounded for the United Kingdom's "dash for gas," as the media here have dubbed it.

As early as this week, a moratorium on shale gas production is expected to be lifted. And plans to streamline and speed the regulatory process through a new Office for Unconventional Gas and Oil were unveiled last week in the annual autumn budget statement by the chancellor of the exchequer, George Osborne.

In the U.K., where all underground mineral rights concerning fossil fuels belong to the crown, hydraulic fracturing, or fracking, could unlock a new stream of government revenue as well as fuel. But it also means that there is no natural constituency of fracking supporters as there is in the United States, birthplace of the technology. In the U.S., concerns over land and water impact have held back fracking in some places, like New York, but production has advanced rapidly in shale basins from Texas to Pennsylvania, with support of private landowners who earn royalties from leasing to gas companies. (Related: "Natural Gas Stirs Hope and Fear in Pennsylvania")

A taste of the fight ahead in the U.K. came ahead of Osborne's speech last weekend, when several hundred protesters gathered outside of Parliament with a mock 23-foot (7-meter) drilling rig. In a letter they delivered to Prime Minister David Cameron, they called fracking "an unpredictable, unregulatable process" that was potentially toxic to the environment.

Giving shale gas a green light "would be a costly mistake," said Andy Atkins, executive director of the U.K.'s Friends of the Earth, in a statement. "People up and down the U.K. will be rightly alarmed about being guinea pigs in Osborne's fracking experiment. It's unnecessary, unwanted and unsafe."

The government has countered that natural gas-fired power plants would produce half the carbon dioxide emissions of the coal plants that still provide about 30 percent of the U.K.'s electricity. London Mayor Boris Johnson, viewed as a potential future prime minister, weighed in Monday with a blistering cry for Britain to "get fracking" to boost cleaner, cheaper energy and jobs. "In their mad denunciations of fracking, the Greens and the eco-warriors betray the mindset of people who cannot bear a piece of unadulterated good news," he wrote in the Daily Telegraph.

Energy Secretary Edward Davey, who is expected this week to lift the U.K.'s year-and-a-half-old moratorium on shale gas exploration, said gas "will ensure we can keep the lights on as increasing amounts of wind and nuclear come online through the 2020s."

A Big Role for Gas

If the fracking plan advances, it will not be the first "dash for gas" in the U.K. In the 1980s, while Prime Minister Margaret Thatcher battled with mining unions, she undercut their clout by moving the nation toward generating a greater share of its electricity from natural gas and less from coal. So natural gas already is the largest electricity fuel in Britain, providing 40 percent of electricity. (Related Interactive: "World Electricity Mix")

The United Kingdom gets about 10 percent of its electricity from renewable energy, and has plans to expand its role. But Davey has stressed the usefulness of gas-fired plants long-term as a flexible backup source to the intermittent electricity generated from wind and solar power. Johnson, on the other hand, offered an acerbic critique of renewables, including the "satanic white mills" he said were popping up on Britain's landscape. "Wave power, solar power, biomass—their collective oomph wouldn't pull the skin off a rice pudding," he wrote.

As recently as 2000, Great Britain was self-sufficient in natural gas because of conventional gas production in the North Sea. But that source is quickly drying up. North Sea production peaked in 2000 at 1,260 terawatt-hours (TWH); last year it totaled just 526 TWh.

Because of the North Sea, the U.K. is still one of the world's top 20 producers of gas, accounting for 1.5 percent of total global production. But Britain has been a net importer of gas since 2004. Last year, gas imports—mainly from Norway, Belgium, and the Netherlands—accounted for more than 40 percent of domestic demand.

The government hopes to revive domestic natural gas production with the technology that has transformed the energy picture in the United States—horizontal drilling into deep underground shale, and high-pressure injection of water, sand, and chemicals to create fissures in the rock to release the gas.

A Tougher Road

But for a number of reasons, the political landscape is far different in the United Kingdom. Britain made a foray into shale gas early last year, with a will drilled near Blackpool in northwest England. The operator, Cuadrilla, said that that area alone could contain 200 trillion cubic feet of gas, which is more than the known reserves of Iraq. But the project was halted after drilling, by the company's own admission, caused two small earthquakes. (Related: "Tracing Links Between Fracking and Earthquakes" and "Report Links Energy Activities To Higher Quake Risk") The April 2011 incident triggered the moratorium that government now appears to be ready to lift. Cuadrilla has argued that modifications to its procedures would mitigate the seismic risk, including lower injection rates and lesser fluid and sand volumes. The company said it will abandon the U.K. unless the moratorium is soon lifted.

A few days ahead of Osborne's speech, the Independent newspaper reported that maps created for Britain's Department of Energy and Climate Change (DECC) showed that 32,000 square miles, or 64 percent of the U.K. countryside, could hold shale gas reserves and thus be open for exploration. But a DECC spokeswoman said "things are not quite what it [the Independent story] suggests." Theoretically, she said, those gas deposits do exist, but "it is too soon to predict the scale of exploration here." She said many other issues, ranging from local planning permission to environmental impact, would mean that some tracts would be off limits, no matter how much reserve they held. DECC has commissioned the British Geological Survey to map the extent of Britain's reserves.

Professor Paul Stevens, a fellow of the Royal Institute of International Affairs, said the U.K. is clearly interested in trying to replicate America's shale gas revolution. "That's an important part of the story," he said, but trying to use the American playbook won't be easy. "It's a totally different ballgame." In addition to the fact that mineral rights belong to the crown, large expanses of private land that are commonplace in America don't exist in England. Just as important, there is no oil- and gas-service industry in place in Britain to quickly begin shale gas operations here. "We don't have the infrastructure set up," said Richard Davies, director of the Durham Energy Institute at Durham University, adding that it would take years to build it.

Shale gas production would also likely ignite bigger and louder protests in the U.K. and Europe. "It's much more of a big deal in Europe," Stevens said. "There are more green [nongovernmental organizations] opposed to it, and a lot more local opposition."

In any case, the U.K. government plans to move ahead. Osborne said he'll soon begin consultations on possible tax breaks for the shale gas industry. He also announced that Britain would build up to 30 new natural gas-fired power plants with 26 gigawatts (GW) of capacity. The new gas plants would largely replace decommissioned coal and nuclear power plants, though they would ultimately add 5GW of additional power to the U.K. grid. The coalition government's plan, however, leaves open the possibility of increasing the amount of gas-generated electricity to 37GW, or around half of total U.K. demand.

The U.S. Energy Information Administration (EIA) estimates that Europe may have as much as 600 trillion cubic feet of shale gas that could be recovered. But Stevens said no European country is ready to emulate the United States in producing massive amounts of unconventional gas. They all lack the necessary service industry, he said, and geological differences will require different technologies. And governments aren't funding the research and development needed to develop them.

Globally, the track record for efforts to produce shale gas is mixed:

• In France, the EIA's estimate is that shale gas reserves total 5 trillion cubic meters, or enough to fuel the country for 90 years. But in September, President Francois Hollande pledged to continue a ban on fracking imposed last year by his predecessor, Nicolas Sarkozy.
• Poland was also thought to have rich shale gas resources, but initial explorations have determined that original estimates of the country's reserves were overstated by 80 percent to 90 percent. After drilling two exploratory wells there, Exxon Mobil stopped operations. But because of its dependence on Russian gas, Poland is still keen to begin shale gas production.
• South Africa removed a ban on fracking earlier this year. Developers are eyeing large shale gas reserves believed to underlie the semidesert Karoo between Johannesburg and Cape Town.
• Canada's Quebec Province has had a moratorium on shale gas exploration and production, but a U.S. drilling company last month filed a notice of intent to sue to overturn the ban as a violation of the North American Free Trade Agreement.
• Germany's Environment Ministry has backed a call to ban fracking near drinking water reservoirs.
• China drilled its initial shale gas wells this year; by 2020, the nation's goal is for shale gas to provide 6 percent of its massive energy needs. The U.S. government's preliminary assessment is that China has the world's largest "technically recoverable" shale resources, about 50 percent larger than stores in the United States.

Royal Hoax: Station to Give $500K to Nurse's Family

The Australian radio station that employed the DJs who prank-called the London hospital where Kate Middleton was being treated has cancelled their show and will donate at least $500,000 to the grieving husband and children of the nurse who took the call and later apparently killed herself.

Australia's 2Day FM released a statement today saying it hopes to "help [Jacintha] Saldanha's family with the support they need at this very difficult time."

After days of suspended advertising, the radio station at the center of a global firestorm announced it will resume airing commercials Thursday. All its profits for the rest of the year will go directly to the family of the unsuspecting nurse at the center of that joke.

The Sydney-based station also issued a company-wide suspension of prank calls after the nurse who initially answered the hospital call was found dead.

Saldanha's husband and two teenage children met with officials at the hospital Monday, and spoke publicly for the first time, although via a member of the British Parliament.

Royal Hospital Hoax: End to Shock-Jock Pranks? Watch Video

Australian DJs Apologize in Wake of Nurse's Suicide Watch Video

"This is a close family," Keith Vaz said. "They are devastated by what has happened. They miss her every moment of every day.

Although radio pranks have been a staple of shock DJs for years, DJs Mel Greig and Michael Christian of Australia's 2Day FM might have crossed the line last week when they pranked the hospital, prompting the question of whether this is the end for radio pranking.

"Entertainers try to use real-life everyday circumstances and try to find humor in them," Radio DJ J Niice of B96 in Chicago, who does regular pranks on his show, told ABC News.

DJ Niice says his station has no intentions of pulling the plug on prank calls because it doesn't need to.

Based on U.S. law, such calls only become problematic when any resulting damage or injury could have been foreseen.

Former Alaska Gov. Sarah Palin was famously pranked while running for vice president by a notorious Montreal-based comedy duo, who pretended to be then-French President Nicolas Sarkozy.

"You know, I see you as a president one day," one of them told Palin, to which she replied with a giggle, "Maybe in eight years.'"

A prank caller even managed to make his way through security to speak to Tony Blair while he was still British prime minister. But it was no laughing matter in 1998 when Opie and Anthony, DJs from a Boston radio station, were fired for telling listeners on April Fools' Day that the city's mayor had died in a car accident.

While the Australian DJs' show has been terminated, it's still unclear whether they will be.

They could face criminal charges if police determine their call was illegally recorded. And the same joke at which they initially laughed is now the reason for their tears.

Doha summit launches climate damage aid

The latest summit to stop climate change, held in Doha, Qatar, over the past two weeks has been roundly slammed. Little was agreed to curb greenhouse gas emissions and the latest modelling, carried out by the Climate Action Tracker consortium shows global averages temperatures are still set to rise by at least 3 °C above pre-industrial levels.

There was one breakthrough: developing countries won a promise from developed ones that they would compensate them for losses and damage caused by climate change. The deal offers the promise of large amounts of climate aid. But first, science will have to catch up with politics.

All countries will suffer from climate change. There will be consequences even if humanity slashed its emissions and stopped temperatures rising more than 2 °C above pre-industrial levels, the stated goal of the UN negotiations. In actual fact, with emissions rising faster than ever, a 3 or 4 °C rise is likely this century.

The consequences will be manifold. Deserts will spread and lethal heatwaves become more frequent. Changes in rainfall will bring droughts, floods and storms, while rising seas will swamp low-lying areas, obliterating valuable territory. Food production will fall.

Before Doha kicked off, the charities ActionAid, CARE International and WWF released a report arguing that rich countries should compensate poor countries for such damages. Tackling the Limits to Adaptation points out that climate change will cost countries dearly, both economically and in less tangible ways such as the loss of indigenous cultures.

Two-pronged approach

So far, climate negotiations have taken a two-pronged approach to the problem. On the one hand, they have sought to create incentives or imperatives to cut emissions. On the other, they have established a pot of money for poor countries to pay for measures that will help them fend off the unavoidable consequences of climate change – such as sea walls and irrigation systems.

That, according to some, leaves a third element missing. Helping those who suffer the consequences of climate change is a moral obligation and must be part of any treaty on climate change, says Niklas Höhne of renewable energy consultancy Ecofys. The idea of climate compensation has been around since the early 1990s, when the United Nations Framework Convention on Climate Change was negotiated.

In Doha, a coalition including China, the Alliance of Small Island States and the G77 group of developing countries pushed for it to revived.

They proposed a scheme that would decide when countries had suffered climate harms, and compensate them. It would be a form of insurance, and the greatest international aid scheme ever. The idea gained momentum after Typhoon Bopha struck the Philippines last week, and that country's negotiator Naderev "Yeb" Saño broke down in tears during a speech. And, although developed nations had little incentive to agree, the conference concluded with a promise to set something up next year.

Compensation poses a fundamental challenge to climate science, which still struggles to work out if trends and events are caused by greenhouse gases or would have happened anyway. "We can't say that an individual event was caused by climate change," says Nigel Arnell of the University of Reading, UK. "What we can do is say that the chance of it happening was greater."

Systematic tests

Some climatologists are now running systematic tests to decide whether extreme weather events are caused by climate change. They run climate models with and without humanity's emissions. If the odds of a particular event are different, it suggests it was at least partially driven by emissions. By this measure, the 2003 European heatwave and 2011 Texas drought were both made more likely by human emissions.

But this science is in its infancy. We can confidently attribute large-scale trends and temperature changes, says Kevin Trenberth of the National Center for Atmospheric Research in Boulder, Colorado. But changes in rainfall, and short-term events like hurricanes, are harder because we do not really understand them. Trenberth speculates that superstorm Sandy would not have flooded the New York subways without climate change, but says it's not possible to prove.

Arnell says that might prove unworkable. Gradual changes – such as rising sea levels, melting glaciers and ocean acidification – are easy to attribute to climate change but their consequences difficult to cost; sudden events are easy to cost but difficult to attribute.

There may be another possibility. Rather than examining individual events, climate models could predict the extra climate-related costs each country would experience, allowing regular payouts. "That would be a way round it," says Arnell. Delegates at next year's conference will have to consider these questions.

Positive step

Harjeet Singh of ActionAid in New Delhi, India, calls the Doha deal "a positive step forward". But it is only an agreement in principle: no money was committed, and even a promise to do so in the future was left out of the final text. Edward Davey, the UK's secretary of state for energy and climate change, said it was "far too early" to talk about committing money. "We aren't saying there should be compensation," he said.

Singh says the developed world would save money by cutting emissions now, rather than letting temperatures rise and then paying compensation. Small island states were keen to get an agreement on loss and damage because emissions cuts are going so slowly, making dangerous climate change almost certain. The Doha agreement is a first step towards dealing with the consequences of that failure.

On 'other business'

Aside from agreeing to make compensation available for loss and damage, the Doha summit achieved little. Nearly two decades ago, the world's governments set out to agree a binding deal to cut greenhouse gas emissions. Doha included some baby steps towards a deal in 2015, but that is not guaranteed and in any case will come too late to stop dangerous climate change. Only Lebanon and the Dominican Republic made new emissions pledges.

The talks were bogged down in rows over financing. In a deal that was separate to the adaptation fund, developed countries had promised in 2009 to deliver $100 billion a year by 2020 to help poor nations prepare for climate change. Between 2009 and 2012 they allocated $10 billion a year. In Doha they refused to say how they would scale that up, simply promising to "continue" – leaving developing countries unsure if or when they would get more.

The Kyoto protocol was renewed until 2020, but its global effect is likely to be limited. Its value is partly symbolic, to show that binding agreements can be reached, and as one of many small and medium-scale projects to cut emissions.

US, UK shareholders 'now to pay if bank fails'

LONDON: British and US banking regulators proposed on Monday a joint strategy to ensure that the bankruptcy of big banks won't spark a chain reaction of contagion throughout markets.

The two bodies, acting on behalf of the two largest financial centres in the world, stressed that under the proposals, shareholders and not taxpayers would bear the full costs, and top managers would be sacked.

At the Bank of England, the deputy governor for financial stability Paul Tucker said: "The 'too big to fail' problem simply must be cured. We believe it can be and that this joint paper provides evidence of the serious progress that is being made."

The British and US authorities said in a joint statement that the financial crisis had "driven home the importance of an orderly resolution process for globally active, systemically important, financial institutions" which have foundered.

They said that their solutions, which would target the parent of any finance house in trouble, "have been designed to enable large and complex cross-border firms to be resolved without threatening financial stability and without putting public funds at risk."

They said they had borne in mind work by the G20-backed Financial Stability Board on principles for dealing with failed financial institutions.

There has been widespread criticism of the way in which Lehman Brothers investment bank was closed down, triggering a massive crisis of confidence, and that in the disruption that followed some shareholders did not carry the full brunt of the costs and some managers held on to their boardroom jobs.

In the United States and in Europe, governments had to use taxpayers' funds to provide guarantees or new capital to financial institutions in trouble. Creditors lost money but most depositors were protected.

The objective is to minimise the dangers of so-called "systemic risk", when a sudden loss of confidence threatens to trigger chaos throughout the financial system as nearly occurred in 2007.

The strategy by the Bank of England and the US Federal Deposit Insurance Corporation is a response to the traumas and lessons of the financial crisis which followed.

The statement said that the British part of the strategy was intended to fit with the powers provided by the UK Banking Act of 2009 "and in anticipation of the further powers that will be provided by the European Union Recovery and Resolution Directive."

Britain, a member of the European Union but not of the eurozone, is campaigning hard on another front which has a bearing on bank resolution: this is progress towards an EU banking union, built initially around the 17 eurozone members with banking supervision vested in the European Central Bank.

Britain is concerned that this could become a back door way for eurozone and EU authorities to interfere in regulation of the financial sector in Britain in a way which would damage British interests.

The statement said that the proposals were based on a "top-down" strategy for dealing with financial firms in severe difficulty, whereby a single authority would apply its powers "to the top of a financial group, that is, at the parent company level" and across borders.

In the United States the measures would work in the context of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010.

"Such a strategy would apply a single receivership at the top-tier holding company, assign losses to shareholders and unsecured creditors of the holding company, and transfer sound operating subsidiaries to a new solvent entity or entities," said the statement.

Both the US and British approaches would "ensure continuity of all critical services performed by the operating firm(s), thereby reducing risks to financial stability."

The joint statement said: "The unsecured debt holders can expect that their claims would be written down to reflect any losses that shareholders cannot cover, with some converted partly into equity in order to provide sufficient capital."

Subsidiaries which were viable would be kept open and operating, "thereby limiting contagion effects and crossborder complications."

The statement also made clear that action to deal with financial firms in trouble "would be accompanied by the replacement of culpable senior management."

Samsung video hints at big release at CES

Samsung's Galaxy S3

(Credit:
Josh Miller/CNET)

A teasing post on Samsung's site suggests a new product will be revealed at
CES 2013.

In a blog post and video, the electronics giant says that its customers should "get ready" for January 8 to 11 -- the dates of the Consumer Electronics show -- and should stay tuned to learn more.

The video doesn't give much away. But the phrase "the world is waiting" may be indicative of previous rumors concerning a potential successor to Samsung's Galaxy S3 smarphone, which debuted in May. The company actually quashed such rumors in September via Twitter.

The presumed the Galaxy S4 could potentially feature a quad-core processor and 13-megapixel camera, according to rumors. In addition, there is also word that the next-generation flagship model for the electronics giant may come equipped with an "unbreakable" screen. Below is the video:

Plants Grow Fine Without Gravity

When researchers sent plants to the International Space Station in 2010, the flora wasn't meant to be decorative. Instead, the seeds of these small, white flowers—called Arabidopsis thaliana—were the subject of an experiment to study how plant roots developed in a weightless environment.

Gravity is an important influence on root growth, but the scientists found that their space plants didn't need it to flourish. The research team from the University of Florida in Gainesville thinks this ability is related to a plant's inherent ability to orient itself as it grows. Seeds germinated on the International Space Station sprouted roots that behaved like they would on Earth—growing away from the seed to seek nutrients and water in exactly the same pattern observed with gravity. (Related: "Beyond Gravity.")

Since the flowers were orbiting some 220 miles (350 kilometers) above the Earth at the time, the NASA-funded experiment suggests that plants still retain an earthy instinct when they don't have gravity as a guide.

"The role of gravity in plant growth and development in terrestrial environments is well understood," said plant geneticist and study co-author Anna-Lisa Paul, with the University of Florida in Gainesville. "What is less well understood is how plants respond when you remove gravity." (See a video about plant growth.)

The new study revealed that "features of plant growth we thought were a result of gravity acting on plant cells and organs do not actually require gravity," she added.

Paul and her collaborator Robert Ferl, a plant biologist at the University of Florida in Gainesville, monitored their plants from the Kennedy Space Center in Florida using images sent from the space station every six hours.

Root Growth

Grown on a nutrient-rich gel in clear petri plates, the space flowers showed familiar root growth patterns such as "skewing," where roots slant progressively as they branch out.

"When we saw the first pictures come back from orbit and saw that we had most of the skewing phenomenon we were quite surprised," Paul said.

Researchers have always thought that skewing was the result of gravity's effects on how the root tip interacts with the surfaces it encounters as it grows, she added. But Paul and Ferl suspect that in the absence of gravity, other cues take over that enable the plant to direct its roots away from the seed and light-seeking shoot. Those cues could include moisture, nutrients, and light avoidance.

"Bottom line is that although plants 'know' that they are in a novel environment, they ultimately do just fine," Paul said.

The finding further boosts the prospect of cultivating food plants in space and, eventually, on other planets.

"There's really no impediment to growing plants in microgravity, such as on a long-term mission to Mars, or in reduced-gravity environments such as in specialized greenhouses on Mars or the moon," Paul said. (Related: "Alien Trees Would Bloom Black on Worlds With Double Stars.")

The study findings appear in the latest issue of the journal BMC Plant Biology.

Royal Hoax: DJs 'Shattered' After Nurse's Suicide

The two Australian radio DJs who prank-called the London hospital where Kate Middleton was being treated last week said they were "shattered" and "gutted" after the nurse who answered their call apparently killed herself.

Shock jocks Mel Greig, 30, and Michael Christian, 25, cried as they spoke to Australia's Channel 9 overnight in their first public interview since Jacintha Saldanha, 46, the nurse who last week connected the pair to the duchess' room, was found dead Friday morning.

"I'm shattered, gutted, heartbroken," Christian said. "Mel and myself are incredibly sorry for the situation and what's happened. I had the idea. … It was just a simple harmless phone call. It was going to go on for 30 seconds. We were going to get hung up on."

FULL COVERAGE: Royal Baby

The host of the "2Day" FM radio show pretended to be Queen Elizabeth and Prince Charles, asking for an update on Middleton's condition when they called up King Edward VII Hospital in central London. With no receptionist on duty overnight, Saldanha answered the prank call and put it through.

"It was just something that was fun and light-hearted and a tragic turn of events that I don't think anyone had expected," Christian said.

Jacintha Saldanha Dead: Could DJs Face Charges? Watch Video

Jacintha Saldanha Outrage: DJs Responsible for Prank Are in Hiding Watch Video

Saldanha was found dead Friday morning after police were called to an address near the hospital to "reports of a woman found unconscious," according to a statement from Scotland Yard.

Investigators have not said how she might have killed herself.

Greig cried today when asked about the moment she heard of the death of Saldanha, a mother of two.

"It was the worst phone call I've ever had in my life," she said through tears. "There's not a minute that goes by that we don't think about her family and the thought that we may have played a part in that is gut-wrenching."

The DJs said they never expected to get through to Middleton's nurse and assumed "the same phone calls had been made 100 times that morning," Christian said.

Grieg said, "We wanted to be hung up on with our silly voices and wanted a 20-second segment to air of us doing stupid voice. … Not for a second did we expect to even speak to Kate or even have a conversation with anyone at the hospital. We wanted to be hung up on."

The global backlash against the duo has been fierce, from online death threats to calls for prison time. Their radio station has announced it is banning phony phone calls altogether, and suspending advertising indefinitely.

Max Moore-Wilton, the chairman of Southern Cross Austereo, said in a letter Sunday to Lord Glenarthur, chairman of King Edward VII's Hospital, that the company is reviewing the station's broadcast policies, the AP reported.

"I can assure you we are taking immediate action and reviewing the broadcast and processes involved," Moore-Wilton said in the letter. "As we have said in our own statements on the matter, the outcome was unforeseeable and very regrettable."

Greig and Michael have been taken off the air, silenced indefinitely.

Female lemurs avoid the wrong love in the dark

IT IS the ultimate voice-recognition system. Without ever meeting him, a female lemur still knows the call of her father.

The ability to identify family members is important to avoid inbreeding. For large-brained mammals like apes that engage in complex social interactions this is relatively straightforward. Now, a team has shown that nocturnal grey mouse lemurs appear to do the same, even though lemurs are reared exclusively by their mothers (BMC Ecology, doi.org/jvx).

Study leader Sharon Kessler of Arizona State University in Tempe, believes that the young lemurs may associate calls similar to their own, or to those of male siblings, with their fathers.

Mandela "comfortable" after night in hospital

JOHANNESBURG: Nelson Mandela is comfortable, after a restful night in hospital for tests, the South African government said Sunday as the former president spent his second day in hospital.

President Jacob Zuma visited the country's first black president and said he had found him "comfortable, and in good care."

It was the second time the 94-year-old and increasingly frail Mandela had been hospitalised this year. While officials are trying to allay fears over his health, they are not releasing any details of his condition.

"I think he has had a restful night, the doctors are comfortable about it, they are continuing monitoring," Mac Maharaj, Zuma's spokesman and a former fellow prisoner with Mandela, told AFP.

The tests and medical attention were consistent with his age, he added.

Medical experts say there is nothing out of the ordinary for a person of Mandela's age to require in-patient attention from time to time.

"We need to understand that he is 94 years old, and that his state of health is not genuinely of a good quality, and that from time to time he is admitted to hospitals," Mark Sonderup, vice chairman of the South African Medical Association told AFP.

The anti-apartheid hero and Nobel Peace Prize laureate was flown from his home village of Qunu in the southeast of the country to a hospital in the capital Pretoria on Saturday.

The once spry boxer, who stayed fit during his 27 years in prison by doing calisthenics in his cell, has grown increasingly frail. But his stature as one of the world's most famous and loved public figures remains undimmed.

"We wish him as speedy recovery," said Ntanyongwana Mdzeki, an octogenarian neighbour of Mandela in Qunu village. "We still need him to be around because he changed our lives."

Mandela's former political colleague Ahmed Kathrada, another apartheid-era prisoner, also wished Mandela a speedy recovery.

"Even in such mundane times as routine hospital visits, you allow South Africans from across the length and breadth of this country to unite in concern for you," said a statement by the Kathrada foundation.

Keith Khoza spokesman of the ruling ANC party, which Mandela once led, said the party wished him well.

"He is in perfect health," he added. "Everything is well. It's just that he has to undergo these regular check ups."

Officials have refused to give more details about his condition or say in which hospital he is being treated.

Security appeared to have been beefed up however at 1 Military Hospital on the outskirts of Pretoria. Military police were searching the trunks of all the cars entering the hospital complex, according to an AFP photographer.

South Africa's military has in the past been responsible for Mandela's health.

The revered statesman has not appeared in public since South Africa hosted the FIFA World Cup final in 2010.

Madiba, as he is affectionately known by South Africans, has all-but retired from public life, choosing to live in his childhood hometown of Qunu in the rural Eastern Cape.

His last hospitalisation was in February when he spent a night in hospital for a minor exploratory procedure to investigate persistent abdominal pain.

In January 2011, Mandela had the country on edge when he was admitted for two nights for an acute respiratory infection. He was discharged in a stable condition for home-based care and intense medical monitoring.

Mandela has also had prostate cancer, for which he was successfully treated in 2001. He had cataract surgery in 1994, just months after he took office as president.

After years fighting white-only rule, he shared the Nobel Peace Prize with the last white president, FW de Klerk, in 1993.

A year later, he crowned his long fight against minority rule by becoming the country's first black president at the end of apartheid.

The last pictures of Mandela published in the media were in August when he received a visit from US Secretary of State Hillary Clinton at his home.

Square, a leader in mobile payments, today launched a gift card service tied to its Square Wallet program and that could be aimed at attracting some would-be Apple Passbook users.

The new service appears designed to let anyone purchase a gift card for friends or family at any of the more than 250,000 businesses nationwide that accept Square Wallet, an iOS and
Android app that lets users pay automatically with their mobile device. The recipient would then redeem the value of the gift using Square Wallet on their own device.

The value of a service like this is that it avoids the use of physical gift cards and lets merchants that accept Square Wallet easily set up the transaction with Square Register, a system that lets them take credit cards, track sales and inventory, and generate analytics.

The gift card business is estimated to be worth $100 billion annually, yet tens of millions of dollars of such gifts expire every day, according to CouponTrade.com. Apple has recently attempted to get in on the gift card game by letting iOS 6 users store the cards in Passbook. Square is clearly hoping it can be the digital gift card service of choice for millions of iOS and Android users. The San Francisco startup has been developing more and more ways for users to pay. It started by providing merchants with plug-in dongles for iOS devices that let anyone take credit cards, and then launched Square Wallet and Square Register.

The company, which is already processing more than $10 billion in annualized transactions, also recently launched a partnership that lets customers pay using Square Wallet at more than 7,000 Starbucks outlets in the United States.

CNET expects to have more detail from Square later today. Please stay tuned.
