NASA planet-hunter is injured and resting

NASA's planet-hunting Kepler telescope has put its search for alien Earths on hold while it rests a stressed reaction wheel.

The injured wheel normally helps to control the telescope's orientation, keeping it pointed continuously at the same patch of sky. Kepler stares at the thousands of stars in its field of view to watch for the telltale blinks that occur when a planet crosses in front of its star. It has found nearly 3000 potential planets outside our solar system since its launch in 2009, transforming the field of exoplanet research and raising hopes of someday finding alien life.

When it launched, Kepler had four reaction wheels: three to control its motion along each axis, and one spare. But last July, one wheel stopped turning. If the spacecraft loses a second wheel, the mission is over.

So when another wheel started showing signs of elevated friction on 7 January, the team decided to play it safe. After rotating the spacecraft failed to fix the problem, NASA announced yesterday that they're placing Kepler in safe mode for 10 days to give the wheel a chance to recover.

The hope is that the lubricating oil that helps the wheel's ball bearings run smoothly around a track will redistribute itself during the rest period.

The telescope can't take any science data while in safe mode. But if the wheel recovers on its own, Kepler's extended mission will run until 2016, leaving it plenty of time to make up for the lost days.

"Kepler is a statistical mission," says Charlie Sobeck, Kepler's deputy project manager at NASA's Ames Research Centre in Mountain View, California. "In the long run, as long as we make the observations, it doesn't matter a lot when we make the observations."

Despite the high stakes, the team doesn't seem too worried.

"Each wheel has its own personality, and this particular wheel has been something of a free spirit," Sobeck says. "It's had elevated torques throughout the mission. This one is typical to what we've seen in the past, and if we had four good wheels we probably wouldn't have taken any action."

"I prefer to picture the spacecraft lounging at the shore of the cosmic ocean sipping a Mai Tai so that she'll be refreshed and rejuvenated for more discoveries," wrote Kepler co-investigator Natalie Batalha in an email.

The team will check up on the wheel on 27 January and return to doing science as soon as possible.

There are two exoplanet missions currently being considered for after Kepler is finished, says Doug Hudgins at NASA Headquarters in Washington, DC. One, TESS (Terrestrial Exoplanet Survey Satellite), would scan the entire sky for planets transiting the stars nearest to the sun. The other, FINESSE (Fast Infrared Exoplanet Spectroscopy Survey Explorer), would take spectra of planets as they passed in front of their stars as a way to probe their atmospheres.

The missions are being evaluated now, and NASA will probably select one this spring, Hudgins says. The winner will launch in 2017.

If Kepler goes down with its reaction wheel, that won't affect which mission wins, he adds. "That's a straight-up competition based on the merits of the two concept study reports."

Tennis: Serena, Murray suck it up to reach sweet 16

MELBOURNE: Serena Williams and Victoria Azarenka came through their first uncomfortable moments and Andy Murray was also tested before reaching the Australian Open's last 16 on Saturday.

Williams, eyeing a calendar-year Grand Slam, was broken for the first time in the tournament by Japanese number one Ayumi Morita, before recovering from 0-3 down in the second set to win 6-1, 6-3.

Defending champion Azarenka screamed at herself and thrashed her racquet before overcoming an unexpectedly stiff challenge by America's Jamie Hampton, who bravely played through severe back pain.

Argentina's Juan Martin Del Potro, seeded six, became the tournament's biggest casualty when the 2009 US Open champion slumped to a five-set defeat to unseeded Frenchman Jeremy Chardy.

Jo-Wilfried Tsonga and Richard Gasquet also went through, and with Gilles Simon playing Gael Monfils later France was assured of having four men in the fourth round, equalling their best performance at the tournament.

In the most competitive day so far, Murray extended his Grand Slam winning streak to 10 matches but not before a thorough workout from hitting partner Berankis, and he let his frustrations show during the 6-3, 6-4, 7-5 win.

The world number three trailed by a break of serve in the second set and appeared agitated at various stages, hitting his racquet on the court and yelling at his courtside box.

Murray served for the match at 5-4 in the third set but Berankis, the world number 110, broke back. But the 22-year-old dropped his next service game and Murray made no mistake in his second attempt at closing the victory.

The Olympic and US Open champion will next face the winner of the all-French affair between Monfils and Simon.

"I was struggling," Murray said. "He (Berankis) was making me feel pretty frustrated. We know each other well and we have practised together. He was making me feel pretty uncomfortable out there."

Williams unleashed her fastest ever serve, a 207 kilometres per hour (128 mph) bullet which equalled a speed clocked in round two against Garbine Muguruza, as she subdued the challenge of Morita.

"I feel today was actually a really good match for me," said Williams, a five-time winner at Melbourne Park and holder of 15 Grand Slam titles.

"I was involved in a lot of longer points, something I definitely wanted. I feel good. I hope I can keep this level up and go higher."

Azarenka admitted she needed to improve "everything" to successfully defend her title after surviving a scare against injured American Hampton, who winced as she played and was close to tears from the pain.

"It was definitely tough," said Azarenka, who won 6-4, 4-6, 6-2 and next plays Elena Vesnina. She is on course to meet Caroline Wozniacki in the quarter-finals.

"It's always good to know you can battle through not playing well, not feeling great."

World number seven Del Potro won four titles last year and dropped just 13 games in the first two rounds, but he found Chardy in inspired form and couldn't recover after going two sets down, finally succumbing in five.

Italy's Andreas Seppi ousted 12th seed Marin Cilic, but Tsonga found it easier with a straight-sets win over Blaz Kavcic, who was on an IV drip just two days ago after playing a five-hour marathon in intense heat.

In the prime-time evening match, four-time champion Roger Federer was due to play Australian upstart Bernard Tomic as he seeks to extend his record number of Grand Slam titles to 18.

Attack at Algeria Gas Plant Heralds New Risks for Energy Development

The siege by Islamic militants at a remote Sahara desert natural gas plant in Algeria this week signaled heightened dangers in the region for international oil companies, at a time when they have been expanding operations in Africa as one of the world's last energy frontiers. (See related story: "Pictures: Four New Offshore Drilling Frontiers.")

As BP, Norway's Statoil, Italy's Eni, and other companies evacuated personnel from Algeria, it was not immediately clear how widely the peril would spread in the wake of the hostage-taking at the sprawling In Amenas gas complex near the Libyan border.

Map by National Geographic

Algeria, the fourth-largest crude oil producer on the continent and a major exporter of natural gas and refined fuels, may not have been viewed as the most hospitable climate for foreign energy companies, but that was due to unfavorable financial terms, bureaucracy, and corruption. The energy facilities themselves appeared to be safe, with multiple layers of security provided both by the companies and by government forces, several experts said. (See related photos: "Oil States: Are They Stable? Why It Matters.")

"It is particularly striking not only because it hasn't happened before, but because it happened in Algeria, one of the stronger states in the region," says Hanan Amin-Salem, a senior manager at the industry consulting firm PFC Energy, who specializes in country risk. She noted that in the long civil war that gripped the country throughout the 1990s, there had never been an attack on Algeria's energy complex. But now, hazard has spread from weak surrounding states, as the assault on In Amenas was carried out in an apparent retaliation for a move by French forces against the Islamists who had taken over Timbuktu and other towns in neighboring Mali. (See related story: "Timbuktu Falls.")

"What you're really seeing is an intensification of the fundamental problem of weak states, and empowerment of heavily armed groups that are really well motivated and want to pursue a set of aims," said Amin-Salem. In PFC Energy's view, she says, risk has increased in Mauritania, Chad, and Niger—indeed, throughout Sahel, the belt that bisects North Africa, separating the Sahara in the north from the tropical forests further south.

On Thursday, the London-based corporate consulting firm Exclusive Analysis, which was recently acquired by the global consultancy IHS, sent an alert to clients warning that oil and gas facilities near the Libyan and Mauritanian borders and in Mauritania's Hodh Ech Chargui province were at "high risk" of attack by jihadis.

"A Hot Place to Drill"

The attack at In Amenas comes at a time of unprecedented growth for the oil industry in Africa. (See related gallery: "Pictures: The Year's Most Overlooked Energy Stories.") Forecasters expect that oil output throughout Africa will double by 2025, says Amy Myers Jaffe, executive director of the energy and sustainability program at the University of California, Davis, who has counted 20 rounds of bidding for new exploration at sites in Africa's six largest oil-producing states.

Oil and natural gas are a large part of the Algerian economy, accounting for 60 percent of government budget revenues, more than a third of GDP and more than 97 percent of its export earnings. But the nation's resources are seen as largely undeveloped, and Algeria has tried to attract new investment. Over the past year, the government has sought to reform the law to boost foreign companies' interests in their investments, although those efforts have foundered.

Technology has been one of the factors driving the opening up of Africa to deeper energy exploration. Offshore and deepwater drilling success in the Gulf of Mexico and Brazil led to prospecting now under way offshore in Ghana, Mozambique, and elsewhere. (See related story: "New Oil—And a Huge Challenge—for Ghana.") Jaffe says the Houston-based company Anadarko Petroleum has sought to transfer its success in "subsalt seismic" exploration technology, surveying reserves hidden beneath the hard salt layer at the bottom of the sea, to the equally challenging seismic exploration beneath the sands of the Sahara in Algeria, where it now has three oil and gas operations.

Africa also is seen as one of the few remaining oil-rich regions of the world where foreign oil companies can obtain production-sharing agreements with governments, contracts that allow them a share of the revenue from the barrels they produce, instead of more limited service contracts for work performed.

"You now have the technology to tap the resources more effectively, and the fiscal terms are going to be more attractive than elsewhere—you put these things together and it's been a hot place to drill," says Jaffe, who doesn't see the energy industry's interest in Africa waning, despite the increased terrorism risk. "What I think will happen in some of these countries is that the companies are going to reveal new securities systems and procedures they have to keep workers safe," she says. "I don't think they will abandon these countries."

Armstrong Tearful Over Telling Kids Truth

Lance Armstrong, 41, began to cry today as he described finding out his son Luke, 13, was publicly defending him from accusations that he doped during his cycling career.

Armstrong said that he knew, at that moment, that he would have to publicly admit to taking performance-enhancing drugs and having oxygen-boosting blood transfusions when competing in the Tour de France. He made those admissions to Oprah Winfrey in a two-part interview airing Thursday and tonight.

"When this all really started, I saw my son defending me, and saying, 'That's not true. What you're saying about my dad? That's not true,'" Armstrong said, tearing up during the second installment of his interview tonight. "And it almost goes to this question of, 'Why now?'

"That's when I knew I had to talk," Armstrong said. "He never asked me. He never said, 'Dad, is this true?' He trusted me."

He told Winfrey that he sat down with his children over the holidays to come clean about his drug use.

"I said, 'Listen, there's been a lot of questions about your dad, about my career and whether I doped or did not dope,'" he said he told them. "'I always denied that. I've always been ruthless and defiant about that, which is why you defended me, which makes it even sicker' I said, 'I want you to know that it's true.'"

He added that his mother was "a wreck" over the scandal.

Armstrong said that the lowest point in his fall from grace and the top of the cycling world came when his cancer charity, Livestrong, asked him to consider stepping down.

Lance Armstrong-Winfrey Interview: How Honest Was He? Watch Video

Lance Armstrong-Winfrey Interview: Doping Confession Watch Video

After the U.S. Anti-Doping Agency alleged in October that Armstrong doped throughout his reign as Tour de France champion, Armstrong said, his major sponsors -- including Nike, Anheuser Busch and Trek -- called one by one to end their endorsement contracts with him.

"Everybody out," he said. "Still not the most humbling moment."

Then came the call from Livestrong, the charity he founded at age 25 when he was diagnosed with testicular cancer.

"The story was getting out of control, which was my worst nightmare," he said. "I had this place in my mind that they would all leave. The one I didn't think would leave was the foundation.

"That was most humbling moment," he said.

Armstrong first stepped down as chairman of the board for the charity before being asked to end his association with the charity entirely. Livestrong is now run independently of Armstrong.

"I don't think it was 'We need you to step down,' but, 'We need you to consider stepping down for yourself,'" he said, recounting the call. "I had to think about that a lot. None of my kids, none of my friends have said, 'You're out,' and the foundation was like my sixth child. To make that decision, to step aside, that was big."

In Thursday's interview installment, the seven-time winner of the Tour de France admitted publicly for the first time that he doped throughout his career, confirming after months of angry denials the findings of the U.S. Anti-Doping Agency, which stripped him of his titles in October.

He told Winfrey that he was taking the opportunity to confess to everything he had done wrong, including for years angrily denying claims that he had doped.

Wind turbines supercharged with superconductors

WIND turbines may soon get a supercharge. Turbines wound with superconducting wire instead of regular copper could turn today's 2 to 3-megawatt generators into 10-megawatt powerhouses, say teams in Europe and the US that are racing to produce the machines.

At heart, a wind turbine is simple - a series of wire coils attached to the rotor blade spin in the presence of strong magnetic fields, provided by stationary magnets. This generates a current, but the resistance in copper wire limits the amount of current that can flow through the coils. Making the coils from a resistance-free superconductor would cut down on weight and boost power generation.

Using superconductors will not be easy, though, partly due to the ultra-low temperatures they require. Developing a coil that can be cooled while simultaneously rotating with the turbine blades is a big challenge. A research project dubbed Suprapower, funded by the European Union, kicked off in December to address this problem.

Holger Neumann at the Karlsruhe Institute of Technology in Germany and other members of the Suprapower consortium are betting on a new "high temperature" superconductor, magnesium diboride, which works at 20 kelvin. "It's light, easily made into wires and is really cheap compared with the old niobium-titanium superconductors, which needed cooling way down to 4 kelvin," Neumann says. That temperature difference might not sound much but it means, crucially, that cooling the magnesium diboride superconductor requires just one-seventh of the power.

The team will also have to build a casing, called a cryostat, in which the superconducting coil will be kept chilled by gaseous helium. This is tricky as its supporting structure will act as a "heat bridge" to the warmer world outside. Neumann thinks they have cracked the problem with a novel arrangement of an outer vacuum vessel and insulating inner layers of plastic and titanium.

But however good their technology, they have to contend with an unusual property of superconductors - when the wires sweep through a magnetic field, their ability to generate current is reduced. That means more coil turns would be needed to make up for the current loss, which would negate some of the weight savings and make the turbines more expensive to construct.

"Magnetic flux lines interfere with the wires' ability to transport electricity, lowering its performance," says Venkat Selvamanickam at the University of Houston, Texas, where the US government is funding work via its Advanced Research Projects Agency - Energy. Selvamanickam's team thinks they have found a way to solve this problem - adding 5-nanometre-wide particles of barium zirconate to the wire. The team found that this "pins" the magnetic flux lines in place as the wires sweep through the field, preventing the formation of swirling magnetic vortices that reduce current flow. So far they have eliminated 65 per cent of this current-limiting problem.

The US team claims to be within a few years of building their own 10-megawatt wind turbine, and says that their techniques could make superconducting wires attractive for distributing electricity as well as generation.

"If we can demonstrate this superconducting-wire technology in a wind turbine, we think it's more likely that it will make its way into the power cables of the electricity grid," says Selvamanickam.

Merrily spins as laser looks on

Lasers could slash wind-turbine power outages, say engineers at Chonbuk National University in South Korea. If the bolts securing turbine blades to a rotor begin to loosen, or blade mass is lost due to a lightning strike, a blade can strike the turbine tower and fall off. But monitoring for when a blade starts to go out of alignment is expensive as it involves peppering each blade with strain sensors.

A cheaper answer is to place a laser on the tower and instead measure the reflection time from every blade as it passes by. This way, deviation of all the blades is measured using just one low-cost sensor (Smart Materials and Structures, doi.org/j62).

Cycling: Livestrong "disappointed" by Armstrong's deception

WASHINGTON: Livestrong, the cancer charity founded by disgraced cyclist Lance Armstrong, said on Thursday it was "disappointed" that he had deceived the organization and many others about doping.

"We at the Livestrong Foundation are disappointed by the news that Lance Armstrong misled people during and after his cycling career, including us," it said after the broadcast of Armstrong's interview with Oprah Winfrey.

Armstrong, 41, used the interview to come clean for the first time about his use of performance enhancing drugs to win seven consecutive Tour de France races, after more than a decade of strident denials.

Prior to recording the interview on Monday in his hometown of Austin, Texas, Armstrong personally went to Livestrong headquarters to apologize to its staff -- and in the interview, he wore its iconic yellow fund-raising wristband.

"We accepted his apology in order to move on and chart a strong, independent course," the foundation said in its statement, received 40 minutes after the conclusion of part one of the broadcast, which will continue on Friday.

"Even in the wake of our disappointment, we also express our gratitude to Lance as a (cancer) survivor for the drive, devotion and spirit he brought to serving cancer patients and the entire cancer community," it said.

"Lance is no longer on the foundation's board, but he is our founder and we will always be grateful to him for creating and helping to build a foundation that has served millions struggling with cancer."

It added: "Our success has never been based on one person. It's based on the patients and survivors we serve every day who approach a cancer diagnosis with hope, courage and perseverance."

Armstrong founded Livestrong in 1997 after he underwent chemotherapy to overcome testicular cancer that had spread to his brain and other parts of his body.

He stepped down first as its chairman, then from its board of directors last year as the US Anti-Doping Agency, in a damning 1,000-page report, put him at the center of the biggest doping conspiracy in the annals of cycling.

Livestrong says it has served more than 2.5 million people affected by cancer and raised more than US$500 million since its founding to support cancer survivors. It does not contribute directly to cancer research.

Opinion: Lance One of Many Tour de France Cheaters

Editor's note: England-based writer and photographer Roff Smith rides around 10,000 miles a year through the lanes of Sussex and Kent and writes a cycling blog at: www.my-bicycle-and-I.co.uk

And so, the television correspondent said to the former Tour de France champion, a man who had been lionised for years, feted as the greatest cyclist of his day, did you ever use drugs in the course of your career?

"Yes," came the reply. "Whenever it was necessary."

"And how often was that?" came the follow-up question.

"Almost all the time!"

This is not a leak of a transcript from Oprah Winfrey's much anticipated tell-all with disgraced cyclist Lance Armstrong, but instead was lifted from a decades-old interview with Fausto Coppi, the great Italian road cycling champion of the 1940s and 1950s.

To this day, though, Coppi is lauded as one of the gods of cycling, an icon of a distant and mythical golden age in the sport.

So is five-time Tour winner Jacques Anquetil (1957, 1961-64) who famously remarked that it was impossible "to ride the Tour on mineral water."

"You would have to be an imbecile or a crook to imagine that a professional cyclist who races for 235 days a year can hold the pace without stimulants," Anquetil said.

And then there's British cycling champion Tommy Simpson, who died of heart failure while trying to race up Mont Ventoux during the 1967 Tour de France, a victim of heat, stress, and a heady cocktail of amphetamines.

All are heroes today. If their performance-enhancing peccadillos are not forgotten, they have at least been glossed over in the popular imagination.

As the latest chapter of the sorry Lance Armstrong saga unfolds, it is worth looking at the history of cheating in the Tour de France to get a sense of perspective. This is not an attempt at rationalisation or justification for what Lance did. Far from it.

But the simple, unpalatable fact is that cheating, drugs, and dirty tricks have been part and parcel of the Tour de France nearly from its inception in 1903.

Cheating was so rife in the 1904 event that Henri Desgrange, the founder and organiser of the Tour, declared he would never run the race again. Not only was the overall winner, Maurice Garin, disqualified for taking the train over significant stretches of the course, but so were next three cyclists who placed, along with the winner of every single stage of the course.

Of the 27 cyclists who actually finished the 1904 race, 12 were disqualified and given bans ranging from one year to life. The race's eventual official winner, 19-year-old Henri Cornet, was not determined until four months after the event.

And so it went. Desgrange relented on his threat to scrub the Tour de France and the great race survived and prospered-as did the antics. Trains were hopped, taxis taken, nails scattered along the roads, partisan supporters enlisted to beat up rivals on late-night lonely stretches of the course, signposts tampered with, bicycles sabotaged, itching powder sprinkled in competitors' jerseys and shorts, food doctored, and inkwells smashed so riders yet to arrive couldn't sign the control documents to prove they'd taken the correct route.

And then of course there were the stimulants-brandy, strychnine, ether, whatever-anything to get a rider through the nightmarishly tough days and nights of racing along stages that were often over 200 miles long. In a way the race was tailor-made to encourage this sort of thing. Desgrange once famously said that his idea of a perfect Tour de France would be one that was so tough that only one rider finished.

Add to this the big prizes at a time when money was hard to come by, a Tour largely comprising young riders from impoverished backgrounds for whom bicycle racing was their one big chance to get ahead, and the passionate following cycling enjoyed, and you had the perfect recipe for a desperate, high stakes, win-at-all-costs mentality, especially given the generally tolerant views on alcohol and drugs in those days.

After World War II came the amphetamines. Devised to keep soldiers awake and aggressive through long hours of battle they were equally handy for bicycle racers competing in the world's longest and toughest race.

So what makes the Lance Armstrong story any different, his road to redemption any rougher? For one thing, none of the aforementioned riders were ever the point man for what the U.S. Anti-Doping Agency has described in a thousand-page report as the most sophisticated, cynical, and far-reaching doping program the world of sport has ever seen-one whose secrecy and efficiency was maintained by ruthlessness, bullying, fear, and intimidation.

Somewhere along the line, the casualness of cheating in the past evolved into an almost Frankenstein sort of science in which cyclists, aided by creepy doctors and trainers, were receiving blood transfusions in hotel rooms and tinkering around with their bodies at the molecular level many months before they ever lined up for a race.

To be sure, Armstrong didn't invent all of this, any more than he invented original sin-nor was he acting alone. But with his success, money, intelligence, influence, and cohort of thousand-dollar-an-hour lawyers-and the way he used all this to prop up the Lance brand and the Lance machine at any cost-he became the poster boy and lightning rod for all that went wrong with cycling, his high profile eclipsing even the heads of the Union Cycliste Internationale, the global cycling union, who richly deserve their share of the blame.

It is not his PED popping that is the hard-to-forgive part of the Lance story. Armstrong cheated better than his peers, that's all.

What I find troubling is the bullying and calculated destruction of anyone who got in his way, raised a question, or cast a doubt. By all accounts Armstrong was absolutely vicious, vindictive as hell. Former U.S. Postal team masseuse Emma O'Reilly found herself being described publicly as a "prostitute" and an "alcoholic," and had her life put through a legal grinder when she spoke out about Armstrong's use of PEDs.

Journalists were sued, intimidated, and blacklisted from events, press conferences, and interviews if they so much as questioned the Lance miracle or well-greased machine that kept winning Le Tour.

Armstrong left a lot of wreckage behind him.

If he is genuinely sorry, if he truly repents for his past "indiscretions," one would think his first act would be to try to find some way of not only seeking forgiveness from those whom he brutally put down, but to do something meaningful to repair the damage he did to their lives and livelihoods.

Armstrong Admits to Doping, 'One Big Lie'

Lance Armstrong, formerly cycling's most decorated champion and considered one of America's greatest athletes, confessed to cheating for at least a decade, admitting on Thursday that he owed all seven of his Tour de France titles and the millions of dollars in endorsements that followed to his use of illicit performance-enhancing drugs.

After years of denying that he had taken banned drugs and received oxygen-boosting blood transfusions, and attacking his teammates and competitors who attempted to expose him, Armstrong came clean with Oprah Winfrey in an exclusive interview, admitting to using banned substances for years.

"I view this situation as one big lie that I repeated a lot of times," he said. "I know the truth. The truth isn't what was out there. The truth isn't what I said.

"I'm a flawed character, as I well know," Armstrong added. "All the fault and all the blame here falls on me."

In October, the U.S. Anti-Doping Agency issued a report in which 11 former Armstrong teammates exposed the system with which they and Armstrong received drugs with the knowledge of their coaches and help of team physicians.

The U.S. Postal Service Cycling Team "ran the most sophisticated, professionalized and successful doping program that sport has ever seen," USADA said in its report.

As a result of USADA's findings, Armstrong was stripped of his Tour de France titles. Soon, longtime sponsors including Nike began to abandon him, too.

READ MORE: Did Doping Cause Armstrong's Cancer?

Armstrong said he was driven to cheat by a "ruthless desire to win."

He told Winfrey that his competition "cocktail" consisted of EPO, blood transfusions and testosterone, and that he had previously used cortisone. He would not, however, give Winfrey the details of when, where and with whom he doped during seven winning Tours de France between 1999 and 2005.

He said he stopped doping following his 2005 Tour de France victory and did not use banned substances when he placed third in 2009 and entered the tour again in 2010.

"It was a mythic perfect story and it wasn't true," Armstrong said of his fairytale story of overcoming testicular cancer to become the most celebrated cyclist in history.

Armstrong would not name other members of his team who doped, but admitted that as the team's captain he set an example. He admitted he was "a bully" but said there "there was a never a directive" from him that his teammates had to use banned substances.

"At the time it did not feel wrong?" Winfrey asked.

"No," Armstrong said. "Scary."

"Did you feel bad about it?" she asked again.

"No," he said.

Armstrong said he thought taking the drugs was similar to filling his tires with air and bottle with water. He never thought of his actions as cheating, but "leveling the playing field" in a sport rife with doping.

Kinect sensor poised to leap into everyday life

WHEN Microsoft's Kinect gaming sensor first exploded onto the gaming scene in 2010, it wasn't long before people started getting excited about what it might make possible.

But despite some imaginative hacks, and even a stint in the operating theatre, the breakthrough depth-sensing technology that made Kinect such a success has had a hard time moving beyond the lab or living room. Now the firm behind the 3D sensor at the heart of the Kinect system is pushing to make the leap into a wide variety of consumer fields far removed from gaming.

At the International Consumer Electronics Show (CES) in Las Vegas last week, Israeli firm PrimeSense showed how their depth sensor, called Carmine, is being put to use in myriad applications. And a smaller version of the sensor may soon be sitting in your smartphone or tablet.

"We're taking it way beyond the living room and putting it into almost anything," says PrimeSense's head of commercial markets, Ohad Shvueli.

Retail is the sector that looks to benefit the most. One firm, Shopperception, uses the sensor to constantly scan the area in front of the shelves in a supermarket to gauge shoppers' behaviour. Because the sensor can track arm movements - just like in Kinect - it knows when a shopper has picked up a certain product. The data is compiled and retailers can see a "heat map" of exactly where on a shelf most customers are reaching.

The sensor is also being put to use by Portuguese firm CoVii, which has written software that lets the sensor turn any simple flat-screen TV or monitor into a "touch-sensitive" device - only the user doesn't have to touch the screen. Because it can detect how far a user's hand is from the screen, it lets people interact by hovering their finger a set distance from the surface - something that would be perfect for interactive advertising displays that could be kept safe behind glass windows.

Meanwhile, California-based Matterport has been using the sensor to cheaply create an accurate, 360-degree 3D scan of a room that is complete within 10 minutes. Such mapping would make buying furniture for your living room a cinch, for example.

Styku, also at CES, has been using the sensor to create a virtual changing room where online shoppers scan their bodies at home and create an avatar to try on outfits to see how they look.

Sean Murphy, an industry analyst for the Consumer Electronics Association, which organises CES, says 3D sensing and gestural control are poised to become a much bigger part of our lives. "It really is the next frontier for getting people interacting with the world around them," he says.

Shvueli agrees, and is pushing hard for the technology to mature into a mainstay of our everyday lives. "Despite Kinect, 3D sensing is a non-existent market at the moment," he says. "We are in the very early stages of making it integrated into everything."

To that end, he says a new version of the sensor, called Capri, will bring depth-sensing to mobile devices. Capri is far smaller than the Carmine sensor, thanks to better heat dissipation. "Once Capri is in a tablet or a smartphone it is going to break the mass market wide open," Shvueli claims. He expects to have Capri sensors installed in commercially available devices next year.

PAP's Dr Koh says he is fighting his own race in by-election

SINGAPORE: People's Action Party (PAP) candidate for Punggol East, Dr Koh Poh Koon, said he is fighting his own race in the by-election.

Dr Koh also stressed that the lack of PAP leaders' presence in his walkabout does not signify that the party places less emphasis on this by-election.

Dr Koh said he prefers to offer a personal touch by interacting directly with residents and believes constituents would also prefer to see and meet the person they will be electing into Parliament.

He said that it is important to address the needs of residents.

Tackling community concerns, he said, will bring immediate reprieve for residents.

Dr Koh was speaking to reporters after his walkabout in the estate.

He ran into the Reform Party's Kenneth Jeyaretnam when he went to the Rivervale Mall for lunch.

The two exchanged pleasantries.

6 Ways Climate Change Will Affect You

Photograph by AP Photo/Marcio Jose Sanchez

The planet keeps getting hotter, new data showed this week. Especially in America, where 2012 was the warmest year ever recorded, by far. Every few years, the U.S. federal government engages hundreds of experts to assess the impacts of climate change, now and in the future.

From agriculture (pictured) to infrastructure to how humans consume energy, the National Climate Assessment Development Advisory Committee spotlights how a warming world may bring widespread disruption.

Farmers will see declines in some crops, while others will reap increased yields.

Won't more atmospheric carbon mean longer growing seasons? Not quite. Over the next several decades, the yield of virtually every crop in California's fertile Central Valley, from corn to wheat to rice and cotton, will drop by up to 30 percent, researchers expect. (Read about "The Carbon Bathtub" in National Geographic magazine.)

Lackluster pollination, driven by declines in bees due partly to the changing climate, is one reason. Government scientists also expect the warmer climate to shorten the length of the frosting season necessary for many crops to grow in the spring.

Aside from yields, climate change will also affect food processing, storage, and transportation—industries that require an increasing amount of expensive water and energy as global demand rises—leading to higher food prices.

Notre Dame: Football Star Was 'Catfished' in Hoax

Notre Dame's athletic director and the star of its near-championship football team said the widely-reported death of the star's girlfriend from leukemia during the 2012 football season was apparently a hoax, and the player said he was duped by it as well.

Manti Te'o, who led the Fighting Irish to the BCS championship game this year and finished second for the Heisman Trophy, said in a statement today that he fell in love with a girl online last year who turned out not to be real.

The university's athletic director, Jack Swarbrick, said it has been investigating the "cruel hoax" since Te'o approached officials in late December to say he believed he had been tricked.

Private investigators hired by the university subsequently monitored online chatter by the alleged perpetrators, Swarbrick said, adding that he was shocked by the "casual cruelty" it revealed.

"They enjoyed the joke," Swarbrick said, comparing the ruse to the popular film "Catfish," in which filmmakers revealed a person at the other end of an online relationship was not who they said they were.

"While we still don't know all of the dimensions of this ... there are certain things that I feel confident we do know," Swarbrick said. "The first is that this was a very elaborate, very sophisticated hoax, perpetrated for reasons we don't understand."

Te'o said during the season that his girlfriend, Lennay Kekua, died of leukemia in September on the same day Te'o's grandmother died, triggering an outpouring of support for Te'o at Notre Dame and in the media.

"While my grandma passed away and you take, you know, the love of my life [Kekua]. The last thing she said to me was, 'I love you,'" Te'o said at the time, noting that he had talked to Kekua on the phone and by text message until her death.

Now, responding to a story first reported by the sports website Deadspin, Te'o has acknowledged that Kekua never existed. The website reported today that there were no records of a woman named Lennay Kekua anywhere.

Te'o denied that he was in on the hoax.

"This is incredibly embarrassing to talk about, but over an extended period of time, I developed an emotional relationship with a woman I met online," Te'o said in a statement released this afternoon. "We maintained what I thought to be an authentic relationship by communicating frequently online and on the phone, and I grew to care deeply about her."

Swarbrick said he expected Te'o to give his version of events at a public event soon, perhaps Thursday, and that he believed Te'o's representatives were planning to disclose the truth next week until today's story broke.

Deadspin reported that the image attached to Kekua's social media profiles, through which the pair interacted, was of another woman who has said she did not even know Te'o or know that her picture was being used. The website reported that it traced the profiles to a California man who is an acquaintance of Te'o and of the woman whose photo was stolen.

"To realize that I was the victim of what was apparently someone's sick joke and constant lies was, and is, painful and humiliating," Te'o said.

Why musical genius comes easier to early starters

Good news for pushy parents. If you want your child to excel musically, you now have better justification for starting their lessons early. New evidence comes from brain scans of 36 highly skilled musicians, split equally between those who started lessons before and after the age of 7, but who had done a similar amount of training and practice.

MRI scans revealed that the white matter in the corpus callosum – the brain region that links the two hemispheres – had more extensive wiring and connectivity in the early starters. The wiring of the late starters was not much different from that of non-musician control participants. This makes sense as the corpus callosum aids speed and synchronisation in tasks involving both hands, such as playing musical instruments.

"I think we've provided real evidence for something that musicians and teachers have suspected for a long time, that early training can produce long-lasting effects on performance and the brain," says Christopher Steele of the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, Germany, and head of the team.

Sweet spot

Steele says that younger-trained musicians may have an advantage because their training coincides with a key period of brain development . At age 7 or 8, the corpus callosum is more receptive than ever to the alterations in connectivity necessary to meet the demands of learning an instrument.

However, he stresses that these connectivity adaptations are no guarantee of musical genius. "What we're showing is that early starters have some specific skills and accompanying differences in the brain, but these things don't necessarily make them better musicians," he says. "Musical performance is about skill, but it is also about communication, enthusiasm, style and many other things we don't measure. So while starting early may help you express your genius, it won't make you a genius," he says.

Nor should older aspiring musicians despair. "They should absolutely not give up. It is never too late to learn a skill," says Steele.

Helicopter crashes in central London

LONDON - A helicopter crashed in central London and plunged to the ground in a ball of flames on Wednesday, with police saying it had hit a crane on top of a building.

Fire engines and police were at the scene of the crash near the River Thames at Vauxhall, where a huge plume of smoke billowed into the sky.

Paul Ferguson, who was working in an office near the incident, told BBC News: "There was a flash and the helicopter plunged to the ground. It exploded and you can imagine the smoke coming out of it."

Witnesses posted photographs of burning wreckage on social networking sites.

Unconfirmed early reports said one person was on board, the pilot.

London's Metropolitan Police said the helicopter was not one of its aircraft. "We had a call at approximately 8am this morning and we are dealing with an incident," a police spokesman said.

The crash was causing long tailbacks on roads during the morning rush hour.

Prosecutor in Aaron Swartz 'hacking' case comes under fire

Carmen Ortiz, U.S. Attorney for Massachusetts

U.S. Department of Justice)

A politically ambitious Justice Department official who oversaw the criminal case against Aaron Swartz has come under fire for alleged prosecutorial abuses that led the 26-year-old online activist to take his own life.

Carmen Ortiz, 57, the U.S. attorney for Massachusetts who was selected by President Obama, compared the online activist -- accused of downloading a large number of academic papers -- to a common criminal in a 2011 press release. "Stealing is stealing whether you use a computer command or a crowbar," Ortiz said at the time. Last fall, her office slapped Swartz with 10 additional charges that carried a maximum penalty of 50 years in prison.

"He was killed by the government," Swartz's father, Robert, said at his son's funeral in Highland Park, Ill., today, according to a report in the Chicago Sun Times.

Last Wednesday, less than three months before the criminal trial was set to begin, Ortiz's office formally rejected a deal that would have kept Swartz out of prison. Two days later, Swartz killed himself.

"He was being made into a highly visible lesson," says Harvey Silverglate, a Cambridge, Mass., attorney who first met Swartz in 2001 and spoke with him after his arrest. "He was enhancing the careers of a group of career prosecutors and a very ambitious -- politically-ambitious -- U.S. attorney who loves to have her name in lights."

Ortiz' spokeswoman did not respond to questions from CNET today. The spokeswoman, Christina Sterling, had said earlier this week: "We want to respect the privacy of the family and do not feel it is appropriate to comment on the case at this time."

Replies Silverglate, the defense attorney and author of the book "Three Felonies a Day:" "It nearly made me puke. Out of deference to the family they weren't going to respond to the charges? It wasn't 'out of deference to the family.' It was out of deference to their careers."

Swartz was accused of 13 felony counts relating to connecting a computer to MIT's network without authorization and retrieving over four million academic journal articles from the JSTOR database (he was allowed to access JSTOR, but not to perform a bulk download). The advocacy group Demand Progress, which Swartz had helped to create and which helped to defeat the Stop Online Piracy Act a year ago, likened it to "trying to put someone in jail for allegedly checking too many books out of the library." (Swartz also sold a company he founded called Infogami to Reddit and was one of the co-creators of the RSS standard for syndicating content.)

If Swartz had stolen a $100 hard drive with the JSTOR articles, it would have been a misdemeanor offense that would have yielded probation or community service. But the sweeping nature of federal computer crime laws allowed Ortiz and Assistant U.S. Attorney Stephen Heymann, who wanted a high-profile computer crime conviction, to pursue felony charges. Heymann threatened the diminutive free culture activist with over 30 years in prison as recently as last week.

The Boston U.S. Attorney's office was looking for "some juicy looking computer crime cases and Aaron's case, sadly for Aaron, fit the bill," Elliot Peters, Swartz's attorney at the Keker & Van Nest law firm, told the Huffington Post. Heymann, Peters says, thought the Swartz case "was going to receive press and he was going to be a tough guy and read his name in the newspaper."

Heymann was also the Boston office's point person in a second investigation that spurred another young hacker to kill himself. In 2008, 24-year-old Jonathan James committed suicide after being named a suspect in a federal cybercrime investigation. His suicide note said: "I have no faith in the 'justice' system. Perhaps my actions today, and this letter, will send a stronger message to the public."

"The charges were ridiculous and trumped-up"

Ortiz has now found herself in an unusual -- and uncomfortable -- position: as the target of an investigation instead of the initiator of one.

An online petition asking President Obama to remove her from office has garnered 35,000 signatures. The threshold at the time for triggering an official White House response, which has not yet happened, was 25,000. (A separate petition asking for the removal of prosecutor Stephen Heymann has attracted only 4,000 signatures so far.)

House Oversight Committee Chairman Darrell Issa, a California Republican, said he has launched an investigation into Ortiz's prosecution of Swartz. It's a bipartisan sentiment: Rep. Jared Polis, a Colorado Democrat and former Internet entrepreneur, told the Hill that: "The charges were ridiculous and trumped-up. It's absurd that he was made a scapegoat."

Rep. Zoe Lofgren, a Democrat whose district includes the heart of Silicon Valley, published draft legislation today (PDF) called "Aaron's Law" that would no longer make it a crime to violate terms of service agreements.

Ortiz had been a rising star in the Democratic Party: a law-and-order Hispanic prosecutor who had won high-profile convictions including Salvatore DiMasi, the former Massachusetts House speaker. The Boston Globe named her "Bostonian of the Year" in 2011 and reported last month that Ortiz was a potential gubernatorial candidate.

Swartz's friends and family have, in the days since his death, argued that Ortiz, Heymann, and assistant U.S. attorney Scott Garland employed tactics should have been reserved for serious criminals, not an activist who merely downloaded more articles than JSTOR would have preferred. A Swartz family statement posted at RememberAaronSW.com says: "The U.S. attorney's office pursued an exceptionally harsh array of charges, carrying potentially over 30 years in prison, to punish an alleged crime that had no victims."

Larry Lessig, the Harvard law professor who spoke at Swartz's funeral today along with Web inventor Tim Berners-Lee, said in a blog post that even though Swartz had no intention of profiting from any downloaded journal articles, "our government continued to push as if it had caught the 9/11 terrorists red-handed."

Alex Stamos, who the defense had planned to call as an expert witness on computer intrusion, said: "I know a criminal hack when I see it, and Aaron's downloading of journal articles from an unlocked closet is not an offense worth 35 years in jail." Law professor Tim Wu added that Ortiz's "legal authority to take down Swartz was shaky" after a federal appeals court ruling last year.

It's true that Swartz would not have faced 50 years in prison; that was, after all, the maximum sentence for his supposed felonies, not the minimum one. But Ortiz and her staff were intent on requiring that he plead guilty to multiple felonies and serve significant time behind bars.

Jennifer Granick, director of civil liberties at Stanford University's Center for Internet and Society and former criminal defense attorney, elaborated on why Swartz was so reluctant to plead guilty:

There was great practical risk to Aaron from pleading to any felony. Felons have trouble getting jobs, aren't allowed to vote (though that right may be restored) and cannot own firearms (though Aaron wasn't the type for that, anyway). More particularly, the court is not constrained to sentence as the government suggests. Rather, the probation department drafts an advisory sentencing report recommending a sentence based on the guidelines. The judge tends to rely heavily on that "neutral" report in sentencing... If he plead guilty to a felony, he could have been sentenced to as many as 5 years, despite the government's agreement not to argue for more. Each additional conviction would increase the cap by 5 years, though the guidelines calculation would remain the same. No wonder he didn't want to plead to 13 felonies. Also, Aaron would have had to swear under oath that he committed a crime, something he did not actually believe.

JSTOR has said since 2011 that it had no interest in pursuing criminal charges, and added last weekend that it "regretted" having been drawn into "this sad event." MIT, which reportedly did encourage Ortiz to pursue the case, is now conducting an internal investigation.

Last Wednesday, two days before Swartz took his life, JSTOR said it was making its archives of more than 1,200 different academic journals free for the public to read.

Mars Rover Finds Intriguing New Evidence of Water

The first drill sample ever collected on Mars will come from a rockbed shot through with unexpected veins of what appears to be the mineral gypsum.

Delighted members of the Curiosity science team announced Tuesday that the rover was now in a virtual "candy store" of scientific targets—the lowest point of Gale crater, called Yellowknife Bay, is filled with many different materials that could have been created only in the presence of water. (Related: "Mars Has 'Oceans' of Water Inside?")

Project scientist John Grotzinger, of the California Institute of Technology in Pasadena, said during a press conference that the drill area has turned out "to be jackpot unit. Every place we drive exposes fractures and vein fills."

Mission scientists initially decided to visit the depression, a third of a mile from Curiosity's landing site, on a brief detour before heading to the large mountain at the middle of Gale Crater. But because of the richness of their recent finds, Grotzinger said it may be some months before they begin their trek to Mount Sharp.

The drilling, expected to start this month, will dig five holes about two inches (five centimeters) into bedrock the size of a throw rug and then feed the powder created to the rover's two chemistry labs for analysis.

The drill is the most complex device on the rover and is the last instrument to be used. Project Manager Richard Cook, of NASA's Jet Propulsion Laboratory, said that operating it posed the biggest mechanical challenge since Curiosity's high-drama landing. (Watch video of Curiosity's "Seven Minutes of Terror.")

A Watery Past?

That now-desiccated Mars once had a significant amount of surface water is now generally accepted, but every new discovery of when and where water was present is considered highly significant. The presence of surface water in its many possible forms—as a running stream, as a still lake, as ground water soaked into the Martian soil—all add to an increased possibility that the planet was once habitable. (Watch a video about searching for life on Mars.)

And each piece of evidence supporting the presence of water brings the Curiosity mission closer to its formal goal—which is to determine whether Mars was once capable of supporting life.

Curiosity scientists have already concluded that a briskly moving river or stream once flowed near the Gale landing site.

The discovery of the mineral-filled veins within Yellowknife Bay rock fractures adds to the picture because those minerals can be deposited only in watery, underground conditions.

The Curiosity team has also examined Yellowknife Bay for sedimentary rocks with the rover's Mars Hand Lens Imager (MAHLI).  Scientists have found sandstone with grains up to about the size of a peppercorn, including one shaped like a flower bud that appears to gleam. Other nearby rocks are siltstone, with grains finer than powdered sugar. These are quite different from the pebbles and conglomerate rocks found in the landing area, but all these rocks are evidence of a watery past. (Related: "A 2020 Rover Return to Mars?")

One of the primary reasons Curiosity scientists selected Gale crater as a landing site was because satellite images indicated that water-formed minerals were present near the base of Mount Sharp. Grotzinger said that the minerals' presence so close to the landing site, and some five miles from the mountain, is both a surprise and an opportunity.

The current site in Yellowknife Bay is so promising, Grotzinger said, that he would have been "thrilled" to find similar formations at the mission's prime destination at the base of Mount Sharp.  Now the mission can look forward to the surprises to come at the mountain base while already having struck gold.

NRA Ad Calls Obama 'Elitist Hypocrite'

Jan 16, 2013 12:04am

Pablo Martinez Monsivais/AP Photo

As the White House prepares to unveil a sweeping plan aimed at curbing gun violence, the National Rifle Association has launched a preemptive, personal attack on President Obama, calling him an “elitist hypocrite” who, the group claims, is putting American children at risk.

In 35-second video posted online Tuesday night, the NRA criticizes Obama for accepting armed Secret Service protection for his daughters, Sasha and Malia, at their private Washington, D.C., school while questioning the placement of similar security at other schools.

“Are the president’s kids more important than yours? Then why is he skeptical about putting armed security in our schools, when his kids are protected by armed guards at their school?” the narrator says.

“Mr. Obama demands the wealthy pay their fair share of taxes, but he’s just another elitist hypocrite when it comes to a fair share of security,” it continues. “Protection for their kids and gun-free zones for ours.”

The immediate family members of U.S. presidents – generally considered potential targets – have long received Secret Service protection.

The ad appeared on a new website for a NRA advocacy campaign – “NRA Stand and Fight” — that the gun-rights group appears poised to launch in response to Obama’s package of gun control proposals that will be announced today.

It’s unclear whether the video will air on TV or only on the web. The NRA did not respond to ABC News’ request for comment.  The domain for the website is registered to Ackerman McQueen, the NRA’s long-standing public relations firm.

The White House had no comment on the NRA ad.

In the wake of last month’s mass shooting at Sandy Hook Elementary School, the Obama administration has met with a cross-section of advocacy groups on all sides of the gun debate to formulate new policy proposals.

The NRA, which met with Vice President Joe Biden last week, has opposed any new legislative gun restrictions, including expanded background checks and limits on the sale of assault-style weapons, instead calling for armed guards at all American schools.

Obama publicly questioned that approach in an interview with “Meet the Press” earlier this month, saying, “I am skeptical that the only answer is putting more guns in schools. And I think the vast majority of the American people are skeptical that that somehow is going to solve our problem.”

Still, the White House has been considering a call for increased funding for police officers at public schools and the proposal could be part of a broader Obama gun policy package.

Fifty-five percent of Americans in the latest ABC News/Washington Post poll say they support adding armed guards at schools across the country.

“The issue is, are there some sensible steps that we can take to make sure that somebody like the individual in Newtown can’t walk into a school and gun down a bunch of children in a shockingly rapid fashion.  And surely, we can do something about that,” Obama said at a news conference on Monday.

“Responsible gun owners, people who have a gun for protection, for hunting, for sportsmanship, they don’t have anything to worry about,” he said.

ABC News’ Mary Bruce and Jay Shaylor contributed reporting.

Poison pill: Not all mercury is toxic

A global treaty on mercury pollution will do more harm than good if it bans the vaccine preservative thiomersal

NEXT week, governments from around the world will gather in Geneva to finalise a long-overdue treaty on mercury. The aim of the negotiations is laudable: to ban those mercury-laden products and pollutants that are a danger to human health and the environment.

Among the targets are some of the most toxic products of the industrial age, including methyl mercury. This notorious compound killed and injured thousands in the Japanese city of Minamata in the 1950s and 1960s and still poses a significant global health risk.

Another compound facing a possible ban, however, is a benign medicinal preservative called thiomersal (thimerosal in the US). Although it contains mercury, there is no evidence that it is harmful. In fact, it helps save the lives of well over a million children every year. Banning it would be a grave mistake.

Thiomersal aside, the world clearly needs to deal with mercury pollution. Mercury is a powerful neurotoxin that is especially dangerous to unborn children. Estimating its global impact is difficult but in some populations almost 2 per cent of children are born with mental retardation caused by mercury poisoning.

Much of this mercury comes from industry, which consumes about 3400 tonnes of the element a year. About a third of this is used in batteries, 800 tonnes in a process called chlor-alkali manufacturing and 650 tonnes in so-called artisanal mining.

Most eventually finds its way into the environment, along with mercury released from burning coal, smelting metal, making cement and incinerating waste. Large quantities of mercury are also released by natural processes such as volcanic eruptions, forest fires and erosion. The United Nations Environment Program estimates that the total global emissions of mercury are between 4400 and 7500 tonnes a year.

Mercury released into the environment eventually finds its way into oceans, lakes and rivers, where it is converted into methyl mercury by microorganisms. This toxic compound accumulates up the aquatic food chain and is often concentrated at high levels in fish, shellfish and marine mammals - and ultimately in the people who eat them. Methyl mercury in food is the biggest cause of mercury poisoning.

In comparison to industrial and natural mercury emissions, thiomersal is negligible. The European Union's vaccine industry uses less than 0.25 tonnes of thiomersal a year, corresponding to just 100 kilograms of mercury. The American Academy of Pediatrics has described this as "infinitesimally small".

Thiomersal also serves an irreplaceable function. It has been added to medical products since the 1930s as a preservative, including in vaccines packaged in multi-dose vials. These are especially vulnerable to bacterial and fungal contamination because many doses are drawn from each vial. Single-dose vials, in contrast, are used once and then thrown away.

Vaccinating from multi-dose vials is cheaper than from single-dose ones. Multi-dose vials also take up less space, reducing the amount of refrigerated storage required to get them to where they are needed. They are thus particularly important for poorer countries, which do not have the money or facilities to use single-dose vials for large-scale immunisation programmes.

Currently 120 countries, accounting for 64 per cent of global births, depend on thiomersal-containing vaccines. These prevent an estimated 1.4 million child deaths a year, according to the World Health Organization. At present there is no substitute.

Thiomersal is also added to influenza vaccines, which can be important in developed countries. The consequences of banning the compound are therefore wide-reaching and dramatic.

A number of developing countries have expressed concern over thiomersal's proposed ban. Public health experts around the world, including the WHO, have no doubt about the importance of allowing it to remain in vaccines.

So why has thiomersal been dragged into the negotiations? The debate is partly fuelled by a historic confusion between risks ascribed to methyl mercury and the ethyl mercury in thiomersal. In 1999, the American Academy of Pediatrics and the US Public Health Service issued a joint statement recommending the removal of thiomersal from vaccines as a precautionary measure, following a US Food and Drug Administration review.

At the time there was abundant evidence that methyl mercury was toxic, but little evidence on ethyl mercury. Additional pressure came from rumours of a link between thiomersal and autism. Since then, however, numerous studies have shown that thiomersal is harmless.

In 2006, an expert panel convened by the WHO issued a statement on thiomersal in vaccines, concluding that there was "no evidence of toxicity". It highlighted the fact that while methyl mercury builds up in the body, ethyl mercury is excreted rapidly. The American Academy of Pediatrics has since endorsed the WHO's position.

Nonetheless, a handful of well-meaning campaigners still believe that thiomersal is harmful. Led by two groups - the Coalition for Mercury-free Drugs and SafeMinds - they have brought the thiomersal "debate" into negotiations designed to address environmental problems.

What happens next depends on the negotiators. The latest draft treaty does not specifically name thiomersal, but there is a clause that leaves the door open for additional items to be added.

There is no question that mercury is dangerous. But thiomersal is not a threat, and banning it would create far more human misery than failing to negotiate a treaty at all.
