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.

Football: Hodgson eyes long-awaited England glory

LONDON: As the Football Association begins its 150th anniversary year, England manager Roy Hodgson has challenged his players to provide the ultimate celebration by at least putting themselves in contention to end almost half a century without a trophy.

Hodgson is the latest in a string of managers charged with ending England's wait for a first major honour since their lone World Cup final triumph, against the then West Germany at London's Wembley Stadium in 1966.

But after helping the FA launch its landmark birthday on the London site of its first meeting, the current incumbent in the so-called 'impossible job' refused to accept it may take another 50 years to replicate.

"There's always hope," Hodgson insisted. "Hope springs eternal. But what you have to do to win tournaments is make sure you're regularly among the ones who are up there with a possibility of winning.

"You could compare it to someone who is an amateur darts player. The more darts he throws in and around the centre, one day he will get it in the bullseye.

"If he's spreading them around the board your chances will be less than if he's getting them in the 25 circle."

Hodgson took England to the quarter-finals at Euro 2012, only losing on penalties to Italy -- even though his team's performances were often described as limited by many critics who yearn for England to rely more on technique and finesse than just their famous bulldog spirit.

The FA shares the same ambition; which is why it has built a national academy in central England at St George's Park -- a school for coaches where all 24 national teams will also be based.

And although Hodgson knows any rewards from that venture are a long way down the line, he hasn't ruled out a degree of short-term success if England qualify for the 2014 World Cup finals in Brazil.

"The first thing we have to do of course is qualify for the tournament," he said. "And then when we qualify it will be important that we give a very good account of ourselves at the World Cup in Brazil. And who knows, once you are there you have a chance of winning it.

"I think we have some very good young players coming into the game playing regularly now and showing that they do have the ability to shoulder the burden."

Hodgson was joined at The FA's anniversary launch by several former England managers including Sven-Goran Eriksson, Terry Venables and Fabio Capello, who left the role in controversial circumstances following a row over a decision to strip John Terry of the England captaincy.

But the Italian was all smiles as he said: "We are all friends now. It is very good to come back and see the people I used to work with. I have no problems with anyone.

"You know I can't talk about what happened with England but I am enjoying my life with Russia and my hope is that we play England in Brazil at the World Cup. That would be very good I think."

FA chairman David Bernstein welcomed Capello's participation by insisting: "Fabio is a man of great dignity and I respect him enormously.

"To see him today (Wednesday) and the warmth he showed, and there was a great deal of warmth when we met each other was really fabulous. It's the way it should be. There were hugs all round."

Meanwhile it emerged the FA, which has already arranged anniversary England friendlies against Brazil, Scotland and the Republic of Ireland, was also looking to fit in matches against Argentina and Germany at Wembley in October and November.

Manti Te'o's fake girlfriend was born and died on social media

Manti Te'o gave several interviews about the death of his girlfriend Lennay Kekua.

(Credit:

Manti Te'o's tale was a portrait of a heartbroken football player overcoming adversity -- triumphing over the tragic death of his girlfriend.

The devout Mormon, Notre Dame linebacker, and runner up to the 2012 Heisman Trophy first suffered the loss of his grandmother, then his girlfriend to leukemia. On the day she died, he had one of the best games of his college career, logging 12 tackles.

The only problem is that she didn't die...because she apparently never existed.

In an exhaustive investigation, Deadspin's Timothy Burke and Jack Dickey detail how Te'o started dating a virtual woman and how his relationship flourished on social media -- and, by the same token, how the truth was sleuthed out via those same online avenues.

According to various news stories gathered by Deadspin, Te'o apparently met his fake 22-year-old girlfriend Lennay Kekua after a Stanford vs. Notre Dame football game in November 2009. After talking on the phone, e-mailing, and meeting up in Hawaii, they decided to become a couple in early 2012. After recovering from a
car accident in the summer, she was hospitalized for leukemia -- and didn't survive.

Kekua's last words to Te'o were "I love you," according to a "College GameDay" interview with the football player. And, a "CBS This Morning" profile on Te'o's will to overcome loss, showed a photo of Kekua along with quote from her that said, "Babe, if anything happens to me, you promise that you'll stay there and you'll play and you'll honor me through the way you play."

However, Deadspin discovered that there are no accounts of Kekua's birth, death, or school records. The woman whose pictures graced national newspapers and TV shows as Te'o's deceased girlfriend is actually someone who lives in Torrance, Calif., who has never met the star athlete and does not suffer from leukemia. This woman's identity has been kept anonymous to protect her privacy.

In an interview this evening on CNN's Anderson Cooper, Burke said that Deadspin's investigation began a week ago with an anonymous e-mail. They did a Google search for "Lennay Kekua," but that only turned up links to stories about her death -- nothing from before then.

Calls to Stanford and Southern California mortuaries turned up nothing, he said. The key turned up when they found the photos that represented Kekua and were able to track them back to the actual person in the images. "That sort of opened everything up," he said.

Looking back on social media, Deadspin was able to retrace Te'o and Kekua's virtual relationship, which commenced on Twitter in October 2011. Throughout the course of their courtship, Kekua's Twitter name went from @lovalovaloveYOU to @LoveMSMK to @LennayKay.

All photos associated with Kekua's social media accounts were of the woman who lives in Torrance. Apparently she knew a friend of Te'o's named Ronaiah Tuiasosopo who is believed to have nabbed her photos and helped the football player construct his virtual girlfriend.

While Te'o gave interviews about his relationship with Kekua and her loss, along with details on how they met at Stanford and talked for hours on the phone, he is currently denying any involvement in this hoax.

Notre Dame's spokesman and assistant vice president Dennis Brown told Deadspin that Te'o "had been the victim of what appears to be a hoax in which someone using the fictitious name Lennay Kekua apparently ingratiated herself with Manti and then conspired with others to lead him to believe she had tragically died of leukemia."

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

Even though Kekua never existed, Te'o's grandmother Annette Santiago did pass away on September 11, 2012.

Currently, Te'o's Twitter profile is headed by a quote from Alexandre Dumas' "The Count of Monte Cristo," a well-known novel about a man of many identities. "Life is a storm...You will bask in the sunlight one moment, be shattered on the rocks the next. What makes you a man is what you do when that storm comes."

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."

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."

787 Dreamliner Grounded, Passengers Forced to Evacuate Watch Video

Boeing 787 Dreamliner Deemed Safe Despite Mishaps Watch Video

Jim McNerney, Boeing's chairman, president and CEO, expressed regret about any scheduling disruptions in a written statement, adding that Boeing was "confident the 787 is safe and we stand behind its overall integrity."

"The safety of passengers and crew members who fly aboard Boeing airplanes is our highest priority," McNerney said. "Boeing is committed to supporting the FAA and finding answers as quickly as possible. The company is working around the clock with its customers and the various regulatory and investigative authorities. We will make available the entire resources of The Boeing Company to assist."

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 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.

PAP's Koh Poh Koon describes himself as a man who wants to get things done

SINGAPORE: Someone who wants to get things done and done effectively.

That's how Dr Koh Poh Koon describes himself, believing these traits can help him contribute as the People's Action Party's (PAP) candidate for the Punggol East by-election.

Despite being a new face in the constituency, Dr Koh feels that many residents have warmed up to him.

Despite having only been introduced to Punggol East voters recently, Dr Koh already looks comfortable interacting with the residents. That's because he said, communicating with people comes as second nature given his profession as a surgeon.

"My job as a doctor has allowed me to really be connecting to strangers that just walk into my clinic and within five minutes we've established a rapport.

"They put their lives in my hands to operate for them so I think building up a rapport with people and gaining their trust is something that comes naturally to me because of my training and my profession.

"And I think my personality and disposition does make it easier as well. Be sincere, be yourself, never be a different person, life gets miserable when you put up a facade.

"Second thing, be sincere and ernest and I think people will be able to listen and they can feel it and that much I learned from my patients".

Dr Koh may have been a grassroots volunteer for the last 11 years. But a recent meeting with a low-income Punggol East resident convinced him that he has made the right choice to stand as a PAP candidate in this by-election.

"He said doctor, we don't want handouts, help us get a breakthrough, break our poverty cycle and that really struck me that helping people really goes beyond giving handouts. It's about putting in place programmes that give people a break in life, giving people a future, that there's hope."

Connecting with the residents is of utmost importance to Dr Koh, prompting him to share his humble childhood experience.

"The way to understand a person is to know what he's made of, you need to know where he came from and that's the way of putting forward my life for residents to understand what makes me tick and I think that has achieved some resonance with the residents."

Dr Koh already has plans to provide new services such as daycare for the elderly and health screening programmes within a soon-to-be built community centre.

iPhone 5's initial ramp too big to sustain, says DisplaySearch

Market research firm DisplaySearch said the reduction in shipments of displays for the iPhone 5 -- which reflect shipments of the phone itself -- is real but that it doesn't necessarily mean the device's popularity is suffering.

"We started hearing indications of cutbacks before the new year," Paul Semenza, senior vice president, analyst services, at DisplaySearch, told CNET today.

That said, he doesn't exactly have a negative take on demand for the
iPhone 5.

"It was a very quick ramp up. The Q4 [estimate] was about 61 million [for the iPhone 5]...that may be dialed back a bit, but anything near that number is still huge," he said, referring to an estimate of display shipments for the iPhone 5.

"That would support the theory that the ramp was too much to sustain."

By comparison, shipments of the
iPhone 4S in the first quarter of sales were far below that number.

Looking to the first quarter of 2013, DisplaySearch's original estimate of 57 million has now been reduced to a range of 33 million to 42 million.

Some analysts said improvement in yields -- the number of good components that are produced versus bad -- have been involved in the shipment drop. But Semenza said such a view was problematic. "That's not logical. If the number of orders are cut, that really has nothing to do with yields," he said.

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.

NY Passes Nation's Toughest Gun Law

Today New York became the first state to pass a gun control law -- the toughest in the nation -- since the Sandy Hook Elementary School shooting massacre last month.

Acting one month and a day since the rampage killing that left 20 first-graders and six educators dead, Gov. Andrew Cuomo signed the bill into law shortly after 5 p.m.

Called the New York Safe Act, the law includes a tougher assault weapons ban that broadens the definition of what constitutes an assault weapon, and limits the capacity of magazines to seven bullets, down from 10. The law also requires background checks of ammunition and gun buyers, even in private sales, imposes tougher penalties for illegal gun use, a one-state check on all firearms purchases, and programs to cut gun violence in high-crime neighborhoods.

As he signed the bill into law, Cuomo said it was not only "the first bill" but the "best bill."

"I'm proud to be a New Yorker, because New York is doing something, because we are fighting back, because, yes, we've had tragedies, and yes, we've had too many innocent people lose their lives, and yes, it's unfortunate that it took those tragedies to get us to this point, but let's at least learn from what's happened, let's at least be able to say to people, yes, we went through terrible situations, but we saw, we learned, we responded, and we acted, and we are doing something about it," Cuomo said. "We are not victims.

"You can overpower the extremists with intelligence and with reason and with commonsense," Cuomo continued, "and you can make this state a safer state."

New York's law also aims to keep guns out of the hands of those will mental illness. The law gives judges the power to require those who pose a threat to themselves or others get outpatient care. The law also requires that when a mental health professional determines a gun owner is likely to do harm, the risk must be reported and the gun removed by law enforcement.

The legislation also includes what is called a "Webster provision," named for the two firefighters ambushed on Christmas Eve in Webster, N.Y. The measure would mandate a life sentence with no chance of parole for anyone who kills a first responder.

The National Rifle Association issued a statement after the bill's signing, saying it was "outraged at the draconian gun control bill that was rushed through ... late Monday evening."

"Gov. Andrew Cuomo and the New York State Legislature orchestrated a secretive end-run around the legislative and democratic process and passed sweeping anti-gun measures with no committee hearings and no public input," the statement read. "These gun control schemes have failed in the past and will have no impact on public safety and crime. Sadly, the New York Legislature gave no consideration to that reality. While lawmakers could have taken a step toward strengthening mental health reporting and focusing on criminals, they opted for trampling the rights of law-abiding gun owners in New York, and they did it under a veil of secrecy in the dark of night. The legislature caved to the political demands of a governor and helped fuel his personal political aspirations."
