Doomsday isn't far from many people's imaginations, whether it's the end of the Mayan calendar, the rapture, or a massive asteroid smashing into the Earth. Now, one of these far-flung scenarios may become even less likely.

The European Space Agency announced this week that it's in the beginning phases of an "Asteroid Impact and Deflection Mission" with its U.S. partner Johns Hopkins Applied Physics Laboratory. The eventual goal of the mission is to verify whether scientists can collide with an asteroid that's hurtling through space -- so as to avoid any possible impact with Earth.

"Concepts are being sought for both ground- and space-based investigations, seeking improved understanding of the physics of very high-speed collisions involving both man-made and natural objects in space," the ESA wrote in a statement.

The eventual plan is for scientists to shuttle off two small spacecraft in the year 2020 in pursuit of a 2,625-foot binary asteroid named 65803 Didymos, according to The Verge. Didymos is reportedly traveling side-by-side with a smaller 500-foot twin asteroid.

Using the smaller asteroid as target practice, scientists will point one of the spacecraft at the flying rock and collide with it. The other spacecraft will be in charge of surveying the damage and seeing if the impact changed the course of the twin asteroids.

"Both missions become better when put together -- getting much more out of the overall investment," the ESA's Asteroid Impact and Deflection Mission study manager said in a statement about the benefits of using two spacecraft. "And the vast amounts of data coming from the joint mission should help to validate various theories, such as our impact modelling."

The possibility of an asteroid crashing into Earth isn't actually that far-out of an idea. In 2004, NASA scientists discovered a massive 22 million ton asteroid that was well on course to hit the planet in 2029. However, after copious research, scientists concluded Earth was safe from an impact scenario. NASA also recently ruled out another possible 2036 asteroid collision.

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.

Biden Confirms Support for Second Amendment


Jan 17, 2013 6:41pm







gty joe biden mayors nt 130117 wblog Biden Confirms Support for Second Amendment, Says He Owns Two Shotguns

Alex Wong/Getty Images


One day after President Obama unveiled the administration’s plan to curb gun violence, Vice President Joe Biden today defended their intentions, answering critics who have spoken out against the plan for potentially infringing on the Second Amendment rights of Americans.


“The president and I support the Second Amendment,”  Biden said definitively.


Biden, who’s led the task force on gun violence since the December shooting at Sandy Hook Elementary School, noted that he owns guns.


“I have two shotguns, a 20-gauge and a 12-gauge shotgun,” he said. Later in the speech he said his son Beau was a better shot than he is but that is because Beau is in the Army.


Biden spoke today before the annual U.S. Conference of Mayors’ meeting in Washington, D.C. Not everyone in the audience, Biden noted today, agrees with recommendations the White House put forward yesterday. But he defended the administration’s move to push this issue, at one point addressing the roomful of mayors as if he were speaking to them individually, saying that “murder rates in both of our towns are …  well beyond … what’s remotely tolerable for a civilized circumstance.”


“We’re going to take this fight to the halls of Congress,” he said. “We’re going to take it beyond that. We’re going to take it to the American people. We’re going to go around the country making our case, and we’re going to let the voices, the voice, of the American people be heard. ”


Biden again noted that there will not be consensus across the nation, given cultural differences among the states. In many states, he added, hunting is  “big deal.”


But, he quipped, addressing the use of high-capacity magazines in hunting, “As one hunter told me, if you got 12 rounds — you got 12 rounds, it means you’ve already missed the deer 11 times. You should pack the sucker in at that point. You don’t deserve to have a gun, period, if you’re that bad.”


High-capacity ammunition magazines “leave victims with no chance,” Biden said.


He summed up saying, “Recognizing those differences doesn’t in any way negate the rational prospect of being able to come up with common-sense approaches how to deal with the myriad of problems that relate to gun ownership.”


Biden said the “time is now” to make these changes and scoffed at some alternative strategies, like the proposal from the NRA for an armed guard to be placed in every school.


“We don’t want rent-a-cops in schools armed,” he said. “We don’t want people in schools who aren’t trained like police officers.”

NASA buys blow-up habitat for space station astronauts









































NASA wants to blow up part of the International Space Station – and a Las Vegas firm is eager to help.












The US space agency has signed a $17.8-million contract with Bigelow Aerospace of Nevada to build an inflatable crew habitat for the ISS.












According to details released today at a press briefing , the Bigelow Expandable Activity Module, or BEAM, will launch in 2015. Astronauts on the ISS will test the module for safety and comfort.












BEAM will fly uninflated inside the trunk of a SpaceX Dragon capsule. Once docked and fully expanded, the module will be 4 metres long and 3 metres wide. For two years astronauts will monitor conditions inside, such as temperature and radiation levels.











Bigelow hopes the tests done in orbit will prove that inflatable capsules are safe and reliable for space tourists and commercial research, an idea almost as old as NASA itself. The space agency began investigating the concept of expandable spacecraft in 1958. Space stations like this would be easier to launch and assemble than those with metal components, so would be cheaper. But research ended after a budget crunch in 2000, and Bigelow licensed the technology from NASA.












Stronger skin













The company has made progress, developing shielding that resists punctures from space debris and micrometeorites. BEAM's skin, for instance, is made from layers of material like Kevlar to protect occupants from high-speed impacts. The craft's skin has been tested in the lab alongside shielding used right now on the rest of the ISS, says Bigelow director Mike Gold.












"Our envelope will not only equal but be superior to what is flying on the ISS today. We have a strong and absolute focus on safety," he says.












And we have to be sure that inflatable craft are safe, says William Schonberg, an engineer specialising in orbital debris protection at Missouri University of Science and Technology in Rolla. "The overall risk to the ISS is the sum of the risks of its individual components," he says.












It may seem counter-intuitive, but a flexible, inflatable design is just as likely to survive punishment from space debris as metal shielding, says Schonberg. "Certain composite cloth materials have been shown to be highly effective as shields against [high-speed space] impacts. So depending on what material is used, and in what combination it is used with other materials – such as thermal insulation blankets – the final design could be just as effective and perhaps better than the more traditional all-metal shields used elsewhere on the station."












Gold hopes BEAM will also demonstrate that fabric shielding can limit radiation risks. This is a major worry on missions to the moon or an asteroid say, where astronauts have to spend weeks or months outside Earth's protective magnetic field.












High-energy particles called cosmic rays constantly fly through the solar system, and when they strike metal shielding, they can emit secondary radiation in the form of X-rays. This doesn't happen with Kevlar-based fabric shields and so expandable habitats could be more desirable for travellers heading deeper into space, says Gold.

Sex, Internet, music on tap at Sundance film fest






LOS ANGELES: Sex, the Internet and good old fashioned rock-and-roll will dominate the 29th Sundance Film Festival, the top showcase of independent US cinema that opens Thursday in the snowy mountains of Utah.

Founded by Robert Redford, the annual festival in Park City aims to nurture independent filmmakers who might otherwise be eclipsed by output from the major studios -- while Hollywood uses it to scout new up-and-coming talent.

The January 17-27 event will present 119 feature films from 32 countries, including 51 first-timers and more than 100 world premieres.

Sex and desire, for teenagers and adults, are key themes that will be explored at Sundance in both fictional movies and documentaries, festival director John Cooper told AFP.

"It is undeniable that there are a lot of examinations of sexual relationships in this year's line-up," Cooper said.

"Filmmakers are dealing with sex as power, sex as basic human need and desire, sex from both the male and female point of view," he explained.

"I chalk this up to the fact that independent filmmakers have always been at the forefront as far as tackling fresh ideas and issues -- even taboo subjects."

Among the films sure to create buzz are "Lovelace", starring "Les Miserables" alum Amanda Seyfried in the title role as 1970s porn star Linda Lovelace of "Deep Throat" fame.

Also on the program are "The Lifeguard", about the dangerous relationship between a pool lifeguard and a teenager, and "Interior. Leather Bar", -- an X-rated art film directed by and starring James Franco.

Franco and co-director Travis Mathews have reimagined sexually explicit footage cut from William Friedkin's 1980 thrilled "Cruising", in which Al Pacino played a New York cop who goes undercover in the city's gay S&M scene.

Sundance will also feature several films looking at the world of high-tech and the Internet including "Google and the World Brain", a documentary about the web giant's plans to scan every book in the world.

Ashton Kutcher stars in "jOBS", a biopic about late Apple co-founder Steve Jobs, and director Alex Gibney will unveil "We Steal Secrets: The Story of WikiLeaks", about Julian Assange's whistleblowing website.

On the documentary front, one of the festival's strong points, about 40 films will be screened including "Manhunt", a look at the CIA's hunt for Osama bin Laden and a counterpoint to Kathryn Bigelow's "Zero Dark Thirty".

Another hotly anticipated documentary is "After Tiller", which tells the story of the last four doctors in the United States who still perform third-trimester abortions, after the 2009 assassination of George Tiller.

Documentary filmmakers "approach problems facing our society from a very deep level that is unusual in mainstream media," Cooper said.

"They both expose problems and provide solutions."

The music world will have its moment in the Park City sun, with screenings of documentaries about The Eagles and Russia's Pussy Riot, as well as a film from Foo Fighters frontman Dave Grohl about the iconic Sound City recording studio in Los Angeles.

The festival's parallel out-of-competition Next section is dedicated to low-budget films, while Park City At Midnight will show a selection of horror and B-movie productions.

Amiigo fitness bracelet knows what exercise you're doing




We've seen fitness trackers before, but here's one with impressive smarts. The Amiigo can automatically identify more than 100 activities with custom algorithms.


Amiigo is a waterproof bracelet and shoe clip that not only counts how many bicep curls or golf swings you do, but monitors your heart rate, blood oxygen levels, skin temperature, activity level, and the number of calories burned, according to the gadget's crowdfunding campaign on Indiegogo.


Sensors and machine-learning algorithms identify the exercise you're performing, and store the data in the device before uploading it to your mobile device. The tech can discriminate between running on the treadmill, for instance, and exercising on an elliptical machine.





Past data can be used to recommend better exercise programs, so it's more useful the longer you use it, according to the backers.


The bracelet and clip can monitor your workout together, or you can use only one. The Amiigo also lets you record new exercises and can then log how many reps you perform.


Link it to your iPhone or
Android device with Bluetooth 4.0 and you can use the data to see how well you're doing, or share results with friends.


You can earn points for each workout, and then wager them with friends in exercise competitions, or redeem them for discounts on fitness goods.


It's no surprise that the campaign has already met its $90,000 goal, with early-bird $89 deals on the bands and clips sold out. The Amiigo now starts at $99, but you'll have to wait until June for delivery of these stylish little motivators.


Meanwhile, check out the promo vid below.

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.

FAA Grounds Boeing 787 Dreamliners













The Federal Aviation Administration has ordered the grounding of Boeing 787 Dreamliner jets until their U.S. operator proves that batteries on the planes are safe.


United is the only U.S. carrier flying the Boeing 787s, which have been touted as the planes of the future. However, several operated by overseas airlines have run into recent trouble, the latest because of a feared battery fire on a 787 today in Japan.


The FAA's so-called emergency airworthiness directive is a blow to Boeing, from the same government agency that only days ago at a news conference touted the Dreamliner as "safe." Even Secretary of Transportation Ray LaHood went so far as to say he would have no issue flying on the plane.


Now, United will need to prove to the FAA that there is no battery fire risk on its six Dreamliners. An emergency airworthiness directive is one that requires an operator to fix or address any problem before flying again.


"Before further flight, operators of U.S.-registered Boeing 787 aircraft must demonstrate to the Federal Aviation Administration (FAA) that the batteries are safe and in compliance," the FAA said in a statement today. "The FAA will work with the manufacturer and carriers to develop a corrective action plan to allow the U.S. 787 fleet to resume operations as quickly and safely as possible."








787 Dreamliner Grounded, Passengers Forced to Evacuate Watch Video









Boeing 787 Dreamliner Deemed Safe Despite Mishaps Watch Video







United Airlines responded tonight with a statement: "United will immediately comply with the airworthiness directive and will work closely with the FAA and Boeing on the technical review as we work toward restoring 787 service. We will begin reaccommodating customers on alternate aircraft."


There are some 50 Dreamliners flying in the world, mostly for Japanese airlines, but also for Polish and Chilean carriers.


Overseas operators are not directly affected by the FAA's emergency airworthiness directive -- but Japanese authorities grounded all of their 787s overnight after All Nippon Airways (ANA) said a battery warning light and a burning smell were detected in the cockpit and the cabin, forcing a Dreamliner, on a domestic flight, to land at Takamatsu Airport in Japan.


The plane landed safely about 45 minutes after it took off and all 128 passengers and eight crew members had to evacuate using the emergency chutes. Two people sustained minor injuries on their way down the chute, Osamu Shinobe, ANA senior executive vice president, told a news conference in Tokyo.


ANA and its rival, Japan Airlines (JAL), subsequently grounded their Dreamliner fleets. ANA operates 17 Dreamliner planes, while JAL has seven in service.


Both airlines said the Dreamliner fleet would remain grounded at least through Thursday.


ANA said the battery in question during today's incident was the same lithium-ion type battery that caught fire on board a JAL Dreamliner in Boston last week. Inspectors found liquid leaking from the battery today, and said it was "discolored."


Japan's transport ministry categorized the problem as a "serious incident" that could have led to an accident.


Even more shaken up than the passengers on the Japanese flight may be the reputation of America's largest plane manufacturer, Boeing.


Since the 787 -- with a body mostly made of carbon fiber -- was introduced, it's had one small problem after another. But the nagging battery issue, which caused an onboard fire at Boston's Logan Airport last week, was serious enough for the FAA to ground the plane.


"It's a rough couple weeks for Boeing and ANA," said John Hansman, an MIT professor of aeronautics and astronautics. "I think clearly in the short term this type of bad press has been tough for Boeing. I think in the long haul, this is a good airplane. It's in a good market."

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 matterSpeaker 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.

SDA's Desmond Lim brands himself as dedicated & determined






SINGAPORE: The Singapore Democratic Alliance's (SDA) Desmond Lim has described himself as a dedicated local and determined leader.

Mr Lim is no stranger to the Punggol East ward, having contested there during the 2011 General Election.

It was a setback that Mr Lim said would have made others run away from politics.

The SDA's secretary-general forfeited his S$16,000 election deposit when he garnered around four per cent of votes in the 2011 General Election.

He said his loss in the Punggol East ward only emboldened him to make a comeback. "In life, we have a lot of hurdles. We have a lot of experiences that (have) no smooth rides. But that doesn't mean that we stop from there. Are we going to tell our children 'oh, you fail your examination, that's it, finish. It's the end of the world. Don't study further.' No, we'll encourage them. Never mind, try again."

Mr Lim's brush with elections began in 2001, when he contested in the then Jalan Besar Group Representation Constituency and was defeated.

He lost again in the 2006 General Election, when he contested in the Pasir Ris-Punggol Group Representation Constituency.

With three elections and 20 years in politics under his belt, Mr Lim thinks he has the necessary qualities to represent Punggol East.

"The Parliament must have a diversified voice. We must have more than one, two parties to counter-check and balance of each other."

Since the 2011 loss, Mr Lim said he has built up a grassroots movement comprising over 10 Punggol residents.

"The residents (themselves) should take up the ownership to advocating for what they really need, such as hawker centre, and because of that, safety - road safety, buses, increase the number of buses service."

Mr Lim plans to set aside a third of his allowance as a Member of Parliament to start a residents' insurance scheme, if elected.
