Watch out, Harry Potter: New invisibility cloak (mostly) works

Jealous of Harry Potter's invisibility cloak? Yours could be coming soon. A new cloaking device doesn't work on visible light yet, but it makes objects invisible to microwave light.

By Clara Moskowitz,?Live Science / March 26, 2013

Physicists have created a real-life prototype of an invisibility cloak like the one featured in the "Harry Potter" books and films.

A miniature version of Harry Potter's invisibility cloak now exists, though it works only in microwave light, and not visible light, so far.

Still, it's a nifty trick, and the physicists who've created the new cloak say it's a step closer to realizing the kind of invisibility cloak that could hide a person in broad daylight.

The invention is made of a new kind of material called a metascreen, created from strips of copper tape attached to a flexible polycarbonate film. The copper strips are only 66 micrometers (66 millionths of a meter) thick, while the polycarbonate film is 100 micrometers thick, and the two are combined in a diagonal fishnet pattern.

The creation is a departure from previous attempts to create invisibility cloaks, which have aimed to bend light rays around an object so that they don't scatter, or reflect off it, a technique that relies on so-called bulk metamaterials. Instead, the new cloak uses a technique called mantle cloaking to cancel out light waves that bounce off the shielded object so that none survive to reach an observer's eye.?

"When the scattered fields from the cloak and the object interfere, they cancel each other out and the overall effect is transparency and invisibility at all angles of observation," study co-author Andrea Alu, a physicist at the University of Texas at Austin, said in a statement.

In lab tests, Alu and his colleagues successfully hid a 7-inch-long (18 centimeters) cylindrical rod from view in microwave light. They said the same technology should be able to cloak oddly shaped and asymmetrical objects, too.
?
?"The advantages of the mantle cloaking over existing techniques are its conformability, ease of manufacturing and improved bandwidth," Alu said. "We have shown that you don't need a bulk metamaterial to cancel the scattering from an object ? a simple patterned surface that is conformal to the object may be sufficient and, in many regards, even better than a bulk metamaterial."

In principle, the same kind of cloak could be used to hide objects in the visible range of light, as well, though it may work only for teensy-tiny objects, at least at first.
?
?"In fact, metascreens are easier to realize at visible frequencies than bulk metamaterials and this concept could put us closer to a practical realization," Alu said. "However, the size of the objects that can be efficiently cloaked with this method scales with the wavelength of operation, so when applied to optical frequencies we may be able to efficiently stop the scattering of micrometer-sized objects."

The invention isn't just a novelty to thrill Harry Potter fans and aspiring spies. The researchers say it could have practical applications down the line, such as in noninvasive sensing devices or in biomedical instruments. They described their device in a paper published in the March 26 issue of the New Journal of Physics.

New study aims to prevent sports-related brain injury in youngsters

Mar. 28, 2013 ? Ice hockey accounts for nearly half of all traumatic brain injuries among children and youth participating in organized sports who required a trip to an emergency department in Canada, according to a new study out of St. Michael's Hospital.

The results are part of a first-of-its-kind study led by Dr. Michael Cusimano that looked at causes of sports-related brain injuries in Canadian youth and also uncovered some prevention tactics that could be immediately implemented to make sports safer for kids.

"Unless we understand how children are getting hurt in sport, we can't develop ways to prevent these serious injuries from happening," said Dr. Cusimano, a neurosurgeon and the lead author of the study. "One would think that we know the reasons why kids are having brain injuries in sports, but until know, it was based mainly on anecdotes."

The study used data from The Canadian Hospitals Injury Reporting and Prevention Program to look at the almost 13,000 children and youth aged 5-19 who had a sports-related brain injury between 1990 and 2009. The results appeared in the journal PLOS ONE today.

The researchers categorized injuries by players' ages, what sport they occurred in and what mechanisms had caused them -- "struck by player," "struck by object" (such as net or post), "struck by sport implement" (such as ball or stick), "struck by playing surface" and "other."

Hockey accounted for 44.3 per cent of all injuries and almost 70 per cent of them occurred in children over 10 as a result of player-to-player contact or being hit into the boards.

Dr. Cusimano said they expected to see high numbers in hockey because it's Canada's "national sport."

"This shows that body contact is still an area where we need to make major inroads to preventing brain injuries," Dr. Cusimano said. "For example, enforcing existing rules and making more effective incentives and disincentives about checking from behind could make huge improvements."

Nineteen per cent of the youth who suffered brain injuries got them during soccer, with most in the 10 to 14 or 15 to 19 age group. In these age ranges, the most common cause of injury was being struck by another player, kicks to the head or head-on-head collisions. In the younger group, age five to nine, players were more likely to suffer a traumatic brain injury from striking a surface or a goal post than those in older groups.

"There's a really straightforward solution here," Dr. Cusimano said. "Padding the goal posts could have potentially prevented a large number of these brain injuries in young children."

The results also found that the youngest age group was at the highest risk for getting seriously injured in baseball. Most of the 15.3 per cent of injuries occurred in children under the age of 14, with 45 per cent of them in children under nine.

Ball and bat injuries were most common, with the majority of injuries caused because the players stood too close to the batter or bat and were not supervised by an adult.

"These results give us a very specific prevention message for kids under nine who play baseball: make helmets and supervision a mandatory," said Dr. Cusimano. "The younger the child, the more supervision they need when using things like bats and balls. Simple rules around not being close to the batter can be taught to children and adults."

Football and rugby accounted for 12.9 per cent 5.6 per cent of injuries respectively, and the majority of them were caused by tackling.

Basketball made up 11.6 per cent of injuries, mostly caused by player-to-player elbowing, which increased as players got older.

"There is a real opportunity for prevention here," Dr. Cusimano said. "Having educational programs, proper equipment, rules and other incentives that support a culture of safety in sports should be a mandate of parents, coaches, players, sports organizations, schools, sports sponsors, and other groups like governments."

Funding for the research was provided by the Canadian Institutes of Health Research and the Ontario Neurotrauma Foundation.

(AP Photo/U.S. Marshal's Office, File)(AP Photo/U.S. Marshal's Office)

TUCSON, Ariz. (AP) ? As authorities investigated the rampage that killed six people and wounded former Rep. Gabrielle Giffords, they compiled nearly 3,000 pages of documents that include everything from interviews with survivors and victims to police reports filed from the crime scene. The documents, released Wednesday, provide new insight into how the shooting occurred and the motivations behind gunman Jared Loughner. One of the main themes to emerge was his increasingly erratic behavior, perhaps summed up best by his father as he told investigators: He "just doesn't seem right lately."

A look at some of the major findings:

LOUGHNER

The gunman was polite and cooperative with authorities who were holding him the afternoon following his morning shooting rampage. The conversation as Loughner sat in restraints in an interview room was mainly small talk. Little was said over the four hours. Loughner asks at one point if he can please use the restroom and says "Thank you" when allowed. At another point he complained that "I'm about ready to fall over."

GUNMAN'S MOTHER

Loughner's mother, Amy, described his run-ins with authorities, his use of marijuana and cocaine, his journals and his increasingly erratic behavior. She also says the parents took a shotgun away from Loughner after he was kicked out of a community college and tested him for drugs because his behavior was so strange.

GUNMAN'S FATHER

Randy Loughner said his son became increasingly difficult, and it was a challenge to have a rational conversation with him. "I tried to talk to him. But you can't, he wouldn't let you," he said "Lost, lost, and just didn't want to communicate with me no more."

MENTAL ILLNESS

Despite their son's increasingly bizarre behavior, Loughner's parents never got him help. Randy Loughner said his son had never been diagnosed with a mental illness. Had he seen a doctor, the detective asked. "No," replied the father. The parents were also asked about any journals or writings that Loughner kept. The father said they were written in an indecipherable script.

GOING TO THE SCENE

Loughner went to a convenience store immediately before the shooting and had the clerk call a cab for him. As he waited for the car, he was pacing inside and outside the store and went to the bathroom three or four times. The employee said that as Loughner was waiting for the cab, he looked up at a clock and said, "nine twenty-five, I still got time."

TRAFFIC STOP

A wildlife agent pulled Loughner over earlier in the day for a traffic violation. He cried and said, "I've just had a rough time," and then composed himself, thanked the agent and shook his hand after he was let go with a warning. The agent asked Loughner again if he was OK, and Loughner said he was going home.

THE SCENE

Giffords intern Daniel Hernandez helped tend to his boss after she was shot in the head. In an interview, he described the chaos: "She couldn't open her eyes. I tried to get any responses for her. Um, it looked like her left side was the only side that was still mobile. Um, she couldn't speak. It was mumbled. She was squeezing my hand.

"I did some training as a Certified Nursing Assistant and as a phlebotomist, um, when I was in high school. So I knew that we need to see if she's got a pulse. She was still breathing. Her breathing was getting shallower. Uh, I then lifted her up so that she wasn't flat on the ground against the wall," he said.

BIZARRE VOICEMAIL

On the day of the shooting, Loughner friend Bryce Tierney told investigators that Loughner had called him early in the morning and left a cryptic voicemail that he believed was suicidal. "He just said, 'Hey, this is Jared. Um, we had some good times together. Uh, see you later.' And that's it." He tried to call back, but it was a restricted number that didn't register on his phone.

EDDIE BAUER

Loughner's father considered his son's firing as a salesman at an Eddie Bauer store to be a turning point. Asked about how the firing affected his son, Randy Loughner said: "He just wasn't the same. He just, nothing, nothing worked, seem to go right for him."

GUNS

Loughner bought a 12-gauge shotgun in 2008, but his parents took it away from him after he was expelled from college and administrators recommended that any firearms be taken away. The shotgun was the only gun his parents knew Loughner owned.

CARING FOR GIFFORDS

A firefighter described how he cared for Giffords after arriving at the scene. "You'd ask her to grab your hand and she would grab your hand," he said. He and paramedics rushed her to the hospital in an ambulance, giving her oxygen and an IV.

THE ENCOUNTER

Hernandez described how constituents and other people were lining up to see Giffords, and he was helping people sign in. He recalled handing Loughner a clipboard. "The next thing I hear is someone yell, 'gun,'" he said.

LOUGHNER FRIEND

One-time Loughner friend Zachary Osler was an employee at a store where Loughner later bought a Glock handgun before the shooting. Osler was questioned about seeing Loughner shopping inside, sometime before Thanksgiving. He describes an awkward encounter with his former friend. "His response is nothing. Just a mute facial expression. And just like he, he didn't care." Osler told investigators he had grown uncomfortable with Loughner's personality, "He would say he could dream and then control what he was doing while he was dreaming." Osler says Loughner never mentioned Giffords to him.

REACTION

Osler said when he learned that Loughner was the suspect in the shooting, "my jaw just dropped. And I was like I know this person. Why he would do it? What would his motive be? If he had people help him? I do not know."

UNUSUAL ENCOUNTER

A few weeks before the shooting, Loughner showed up at the apartment of boyhood friend Anthony Kuck with a 9 mm pistol in his waistband. Loughner said he bought the gun for Christmas. He insisted it was for "home protection," Kuck's roommate, Derek Andrew Heintz, told a Pima County Sheriff's detective and FBI agent who interviewed him the evening after the shooting. Loughner left Heintz with a souvenir: A bullet.

POSSESSIONS

Police reports show what authorities found in Loughner's possession after the shooting. In Loughner's left front pocket were two magazines for a Glock, both fully loaded. In his other front pocket was a foldable knife with about a 4-inch blade. In his back right pocket, he had a baggie with some money, a Visa credit card and his Arizona driver's license. He was wearing a black beanie, a black hoodie-type sweatshirt, khaki pants and Skechers shoes.

Developer Choice Of Games gives you story options on Android

Life of a Wizard is more or less a legitimate RPG, in book form. The story is told in first person text, but you get to make all the important decisions, and those decisions shape what kind of person you will be and what your strengths and weaknesses are as well as how the story plays out. It's an awesome concept, and those of us who like to play engrossing games, specifically because we like the stories, will find a lot to love here.

But what I discovered later was that Life of a Wizard is the product of a company called Choice Of Games, and they have made a whole bunch of games like this for Android. And so for the last week I found myself doing little but playing through these games just to see what kind of stuff I could get into.


Also on Android Apps

The Indianapolis 500 is one of the world?s oldest auto races. You can learn more about the cars and the people who race them thanks to this Guest Post from Zinio.


My favorite of these text-based Android games is called Choice of Romance, about a young boy or girl (your choice) who goes to court in a light fantasy universe to try to find a suitable suitor. I chose to be a lady, and as it begins things are fairly typical of this kind of story. Your family wants you to marry the rich yet not particularly interesting or attractive guy, because it will be good for both you and all your relatives. Meanwhile, there is also a dashing man with little money but who seems pretty cool, and also the king is making eyes at you.

In my version of the tale, I chose to court the dashing man while also having an affair with the king, eventually, my suitor found out I was cheating and dumped me, and so I was left to be one of the king's consorts. Eventually, I gained great power in that role, but I wanted it all. So I conspired to kill the queen and take her place. Unfortunately, due to my earlier character-shaping choices I did a poor job of this, and while the queen did end up dead I was found out. Thus, I was beheaded, and so was my father.

That a seemingly mundane story about going to court for the first time could end up with my character being executed was quite thrilling. I always enjoyed those Choose Your Own Adventure novels because I wanted to see how my character could die, and so I found this result to be a positive experience.

I also tried out one called Choice of Zombies, and in that one you go on a grand quest through a world infested by, you guessed it, zombies. This one was a bit different from the others I played, in that the story is dictated by the number of side quests. Yes, even?a text adventure like this has side quests. As you drive around looking for shelter, you can take detours and collect party members, or you can play it safe and try to get through it alone. In this story, outcomes are dictated almost entirely by the yes or no decisions you make, rather than behind the scenes stats you've collected.

I can't say I prefer one method or another. I would say I like both ways of telling the stories. Having complete control over everything you do is fun, but also having these things be a real game of sorts in which what you can do is dictated by our skills is also fun. Hurrah for having both options.

Life of a Wizard, to bring us back to the beginning, is heavily stats-based. You have and develop skills as you grow up and go on adventures, and while it seems every choice has a ton of options you will only be able to take a few or maybe even none of them. That can be frustrating every once in a while, but it also adds to replayability. I've gone through that one three times just to see how it plays out if I choose different skills.

There are still many more of these games I have yet to play, and you'd better believe I'll continue to try them out. I encourage you to do so as well, as these can be quite interesting and fun. Now, if only some ambitious developer would take story structures like these and combine them with real gameplay, and we might have an honest-to-god mobile gaming paradise on our hands. But for now, I'll be happy that these text-based games exist for my enjoyment.

Experts: NKorea training teams of 'cyber warriors'

SEOUL, South Korea (AP) ? Investigators have yet to pinpoint the culprit behind a synchronized cyberattack in South Korea last week. But in Seoul, the focus is fixed on North Korea, which South Korean security experts say has been training a team of computer-savvy "cyber warriors" as cyberspace becomes a fertile battleground in the nations' rivalry.

Malware shut down 32,000 computers and servers at three major South Korean TV networks and three banks last Wednesday, disrupting communications and banking businesses. The investigation into who planted the malware could take weeks or even months.

South Korean investigators have produced no proof yet that North Korea was behind the cyberattack. Some of the malware was traced to a Seoul computer. Without elaborating, police said Monday that some of the malicious code also came from the United States and three European countries, South Korea's Yonhap news agency reported. But South Korea has pointed the finger at Pyongyang in six cyberattacks since 2009, even creating a cybersecurity command center in Seoul to protect the Internet-dependent country from hackers from the North.

It may seem unlikely that impoverished North Korea, with one of the most restrictive Internet policies in the world, would have the ability to threaten affluent South Korea, a country considered a global leader in telecommunications. The average yearly income in North Korea was just $1,190 per person in 2011 ? just a fraction of the average yearly income of $22,200 for South Koreans that same year, according to the Bank of Korea in Seoul.

But for several years, North Korea has poured money into science and technology. In December, scientists succeeded in launching a satellite into space aboard a long-range rocket from its own soil. And in February, North Korea conducted its third nuclear test.

"IT" has become a buzzword in North Korea, which has developed its own operating system called Red Star. The regime also encouraged a passion for gadgets among its elite, introducing a Chinese-made tablet computer for the North Korean market. Teams of developers came up with software for everything from composing music to learning how to cook.

But South Korea and the U.S. believe North Korea also has thousands of hackers trained by the state to carry its warfare into cyberspace, and that their cyber offensive skills are as good as or better than their counterparts in China and South Korea.

"The newest addition to the North Korean asymmetric arsenal is a growing cyber warfare capability," James Thurman, commander of the U.S. forces in South Korea, told U.S. legislators in March 2012. "North Korea employs sophisticated computer hackers trained to launch cyber-infiltration and cyber-attacks" against South Korea and the U.S.

In 2010, Won Sei-hoon, then chief of South Korea's National Intelligence Service, put the number of professional hackers in North Korea's cyber warfare unit at 1,000.

North Korean students are recruited to the nation's top science schools to become "cyber warriors," said Kim Heung-kwang, who said he trained future hackers at a university in the industrial North Korean city of Hamhung for two decades before defecting in 2003. He said future hackers also are sent to study abroad in China and Russia.

In 2009, then-leader Kim Jong Il ordered Pyongyang's "cyber command" expanded to 3,000 hackers, he said, citing a North Korean government document that he said he obtained that year. The veracity of the document could not be independently confirmed.

Kim Heung-kwang, who has lived in Seoul since 2004, speculated that more have been recruited since then, and said some are based in China to infiltrate networks abroad.

What is clear is that "North Korea has a capacity to send malware to personal computers, servers or networks and to launch DDOS-type attacks," he said. "Their targets are the United States and South Korea."

Expanding its warfare into cyberspace by developing malicious computer codes is cheaper and faster for North Korea than building nuclear devices or other weapons of mass destructions. The online world allows for anonymity because it is easy to fabricate IP addresses and destroy the evidence leading back to the hackers, according to C. Matthew Curtin, founder of Interhack Corp.

Thurman said cyberattacks are "ideal" for North Korea because they can take place relatively anonymously. He said cyberattacks have been waged against military, governmental, educational and commercial institutions.

North Korean officials have not acknowledged allegations that computer experts are trained as hackers and have denied many of the cyberattack accusations. Pyongyang has not commented on the most recent widespread attack in South Korea.

In June 2012, a seven-month investigation into a hacking incident that disabled news production system at the South Korean newspaper JoongAng Ilbo led to North Korea's government telecommunications center, South Korean officials said.

In South Korea, the economy, commerce and every aspect of daily life is deeply dependent on the Internet, making it ripe grounds for a disruptive cyberattack.

North Korea, in contrast, is just now getting online. Businesses are starting to use online banking services, and debit cards have grown in popularity. But only a sliver of the population has access to the global Internet, meaning an Internet outage two weeks ago ? which Pyongyang blamed on hackers from Seoul and Washington ? had little bearing on most North Koreans.

"North Korea has nothing to lose in a cyber battle," said Kim Seeongjoo, a professor at Seoul-based Korea University's Department of Cyber Defense. "Even if North Korea turns out to be the attacker behind the broadcasters' hacking, there is no target for South Korean retaliation."

Europe's Cyprus blunder raises important questions about the ...

Nicolas Veron 80x108One week ago, the EU, IMF and European Central Bank agreed to a bailout for Cyprus that would involve a levy on the country?s bank deposits. The terms of the bailout have been met with surprise and fury in Cyprus and across Europe, and were also rejected by Cyprus?s parliament. Nicholas Veron writes that no matter the outcome, the crisis is likely to cause lasting damage to the trust of Eurozone households in the banking system, and to the EU?s plans for banking union.

The late Mike Mussa of the Peterson Institute, a former Chief Economist of the International Monetary Fund (IMF), noted about some episodes of the late-1990s Asian financial turmoil that ?there are three types of financial crises: crises of liquidity, crises of solvency, and crises of stupidity.? This quip comes to mind when considering the developments of the past few days around Cyprus.

The March 16 announcement of an agreement backed by most European leaders and institutions as well as the IMF, which called for a tax (or possibly an unfavorable cash-for-equity swap) on holders of bank deposits, no matter how small, was a policy blunder that is likely to cost the European Union (EU) dearly.

The sequence that led to this ?Saturday-morning plan? is well known. Greece?s sovereign debt restructuring a year ago hit Cypriot banks that had bought Greek bonds, raising doubts about the Cypriot government?s own solvency. Negotiations on a possible bailout by the EU had been seen as inevitable as early as mid-2012. But discussions were frozen until a general election in Cyprus last month. Unfortunately, the delay pushed the timetable of negotiation into German election cycle territory, constraining the latitude of the euro group of eurozone finance ministers, in which Germany is now the unquestioned central actor. Driven by the domestic German political debate, European negotiators were intent on forcing losses on large (read Russia-linked) Cypriot deposits as an indispensable component of the package.

To the surprise of many, the recently elected Cypriot president, Nicos Anastasiades, added a further twist to the tangled situation by suggesting a hit to small depositors as well. According to some reports, he wanted to limit the losses imposed on large depositors in order to preserve the island?s future as an international financial center. All negotiators seem to have accepted this offer before realizing, too late, how damaging it might be to trust in the safety of bank deposits well beyond Cyprus. No easy or painless option was available for Cyprus. However, some of the Saturday-morning plan?s flaws were avoidable.

First, the plan disregarded the lessons of financial history about the high importance of deposit safety, particularly for middle-class households (which is why there usually is an upper limit for explicit deposit insurance, harmonized at ??100,000 in the EU since 2009). Based on the experience of the early 1930s, it is virtually undisputed in the US that a breach of deposit insurance will primarily hurt the ?little guys.? Sheila Bair, the respected former Chairman of the US Federal Deposit Insurance Corporation, has expressed this view with reference to Cyprus. Similar lessons arise from the record of many recent emerging-market crises.

If it is true, as alleged, that Cyprus?s own president was the one who recommended hurting small depositors, European negotiators were not justified in going along. After all, in November 2010 the Troika of the EU, the European Central Bank (ECB) and the IMF rebuffed the Irish authorities? proposal to ?burn? the holders of senior unsecured debt in failed banks. Their concern was to prevent damaging contagion in the rest of Europe. A similar argument was more straightforward and sensible for Cyprus than it had been for Ireland, and should have led them to oppose Mr Anastasiades? proposal from the outset.

Second, the festival of finger-pointing in Brussels and across Europe following the Cyprus debacle shows that the negotiators had no ?plan?B? were the Cypriot Parliament to reject their initial scheme. One must wonder whether the EU is ready to handle the complex Russian side of the Cypriot equation, including the wisdom of depending on Russian goodwill for a solution to the current mess.

Third, the Saturday-morning plan raised profound questions about the democratic nature of EU decision-making. The problem is not that hard measures were to be imposed on the Cypriot population. A loss of autonomy, alas, is the inevitable consequence of the Cypriot state?s inability to meet all its commitments on its own, as Mr. Anastasiades had earlier acknowledged. Moreover, Cyprus has earned no sympathy by rejecting the United Nations plan for the island?s reunification ahead of its entry into the EU in 2004, and for harboring Russian and Russian-linked financial activities widely presumed to be connected with money-laundering.

The problem, rather, lies in the extent to which the European crisis management is now being held hostage by German electoral politics. This dynamic is not new in the euro-crisis, but has reached new heights as Chancellor Angela Merkel?s main opposition, the Social Democratic Party (SPD), has identified Cyprus earlier this year as a ?wedge issue? on which it could challenge her. The SPD calculation was to paint Ms. Merkel as too lenient with shady Russian oligarchs and their ?black money? held in Cypriot banks, while she would presumably be prevented from responding because of a fear of destabilizing Europe?s financial system. In effect, Ms. Merkel called the SPD?s bluff by risking the euro zone?s first bank run. No wonder that placards on Nicosia?s streets carry slogans such as ?Europe is for its people and not for Germany,? or that Athanasios Orphanides, until recently the governor of the Cypriot central bank and a member of the European Central Bank (ECB)?s Governing Council, complains that ?some European governments are essentially taking actions that are telling citizens of other member states that they are not equal under the law.?

It is too early to evaluate the lasting damage, but it is likely to be significant. The Saturday-morning decision-making process leaves an impression of incompetence and groupthink, tainting all of the participating actors, including all euro zone finance ministers, the European Commission, the ECB, and the IMF. The EU?s earlier sense of purpose by committing to a banking union last June and delivering on its first step (the Single Supervisory Mechanism) in December has now been battered. So has the aura of statesmanship and control developed by Ms. Merkel and the ECB. Possibly most damaging, even if the deposit tax is reversed or adjusted, the trust of middle-class households throughout the Eurozone in the safety of their banking system has eroded. Hopefully there will be no immediate deposit flight in other countries than Cyprus. But in future crisis episodes, households will behave in a destabilizing way, assuming Europe?s deposit insurance arrangements are not profoundly reformed. There is an apt parallel with the Deauville declaration by Ms. Merkel and French President Nicolas Sarkozy, endorsing losses for Greek sovereign bondholders in October 2010, which started an 18-months cycle of increasingly negative market expectations throughout Europe.

What now? A week ago, the challenge in Cyprus was to close the fiscal gap with a bailout package. Now it is to close the fiscal gap, and to restore a minimal level of trust in the banking system, without which the economy cannot operate. This raises the bar. The obvious risk is of massive deposit withdrawals whenever the Cypriot banks reopen. Now that the seal on deposit safety has been broken, depositors will do their best to avoid additional taxation or expropriation in a few weeks? or months? time, no matter how many promises are made that this is a unique and once-and-for-all occurrence. Cypriot authorities are likely to address this with a mix of capital controls and deposit freeze, perhaps in the form of conversion of deposits to interest-bearing certificates of deposits, as recently proposed by Lee Buchheit and Mitu Gulati. But ?financial repression? or even incarceration can only last for a limited period of time given the freedoms guaranteed by the EU treaty.

Unlike in previous euro-crisis episodes, there is little the ECB can do alone. The problem is fiscal at the core and must be addressed by elected leaders. They may conclude that it is best to let Cyprus default, impose capital controls and leave the euro zone, an option that was reported to be explicitly considered in European policy circles. But such a move would violate the promise of European leaders to ensure the integrity of the euro zone, no matter what, and potentially set off a chain reaction, including possible bank runs in other euro zone member states, starting with the most fragile ones, such as Slovenia and of course Greece.

On the other hand, it is difficult to see how the risky scenario of a Cyprus exit could be avoided without further fiscal commitments by euro zone partners, including Germany. Their help could be in the form of additional direct transfers to Cyprus to plug the fiscal gap, or some form of guarantee of deposits that would come from the European rather than the national level. A quick but imperfect way to achieve the latter would be for a European entity, possibly the European Stability Mechanism, to provide an unconditional guarantee for a limited but sufficient period of time (say, 18 months) to all national deposit guarantee schemes in the euro zone, up to the ??100,000 European limit. Such ?deposit reinsurance? has been rejected absolutely by European policymakers so far. It would constitute a major contingent financial commitment, even though the trust-enhancing effect would arguably result in an eventual net fiscal benefit for all. But it would be a powerful preemptive tool to make sure a scenario of retail bank run contagion does not materialize, and might also become the only option available to restore confidence if such a scenario were to become reality.

Assuming that the current situation is somehow brought under control, longer term questions beckon, beyond the geopolitical considerations related to Cyprus and its neighborhood. The breach of the deposit guarantee, materialization of the bank run threat, and probable consideration of capital controls will cast the euro zone debate on banking union in a new and starker light. Since mid-2012 and until now, the policy consensus in Europe had been to pretend that the question of supranational deposit insurance, with its direct links to the currently-frozen issue of fiscal union, was important but not urgent, and should be left out of the explicit banking union agenda. This convenient stance will be harder to hold given the Cypriot experience. More broadly, the episode will contribute to an overdue debate about the democratic (or otherwise) nature of European decision-making and the effectiveness of its crisis management, two challenges more tightly connected than many observers realized. A first step might be to recognize the plan of March 16 as a mistake, and to have an honest debate about how it could have been avoided.

Many commentators are puzzled by the general lack of negative financial market reaction to the fast-unfolding events in Cyprus. The most likely reason, to be tested in the next few days, is that investors have been sufficiently impressed by last year?s whatever-it-takes commitments, particularly those by Ms. Merkel and ECB President Mario Draghi. The markets? baseline assumption remains that a last-minute solution will be found after all the brinkmanship. Longstanding observers of the Eastern Mediterranean tend to project a darker mood, as they recall that this is a region in which individuals, groups and nations do not always act in their self-interest. One can only hope that the market?s assessment is the correct one.

Crowdfunding hope for human-powered helicopter project

Last September, the Gamera II team from the A. James Clark School of Engineering got so close to claiming the Sikorsky Prize of US$250,000 for human-powered helicopter flight that the American Helicopter Society must surely have been preparing to pull the dust covers off the safe and hand over the cash. Gamera II features a huge cross-shaped frame with enormous rotors at each of its four points, which are powered by sustained hand and foot pumping from a pilot at the center. It's a design that's been used by many of those attempting to nab the elusive prize (including AeroVelo's Atlas), but Georgia's Kenneth Huff has a rather more compact vision for success.

The project began in the spring of 2010, when Huff stumbled across some information about the Sikorsky competition while researching the building of an engine-powered single-seat helicopter that he was hoping to build after graduating from Middle Georgia State College.

"I am not sure how most people react to the question of human-powered helicopters, but I thought that it would be easy after reading about the competition," Huff told Gizmag. "I really didn't know what I was in for and after looking at Da Vinci III and Yuri I, I began to understand the nature of challenge."

A year later, he enlisted the help of two friends/fellow classmates (Neal Fischer, William Edwards) and requested a US$5,000 development grant from the College to work on a prototype and test the feasibility of building a human-powered helicopter that was much smaller than either Da Vinci III or Yuri I. At this point, the team had not come across the efforts of the University of Maryland's Gamera team, and AeroVelo hadn't yet embarked on its Atlas project.

Happily, the research proposal was accepted and work began on the first prototype. The aim was to develop a small coaxial human-powered helicopter that had the potential for reliable and practical recreational use, something that certainly can't be claimed for Gamera or Atlas. Banking on improvements in rotor efficiency allowing for a substantial reduction in the size of both frames and blades needed for lift, an additional grant in the spring of 2012 (along with a personal cash injection from Huff himself) allowed important design modifications to be made, along with the construction and testing of a new set of rotors.

The specs for the current prototype (and the next model) include a frame made of 6061 T6 aluminum, a 1:1 gearing ratio, and stacked rotors sporting a carbon fiber spar and S1223 airfoil with a weight of 15 pounds (6.8 kg) and total length of 12 feet (3.6 m). The total empty weight of the craft is 110 pounds (49.8 kg).

"The basic premise behind this design is that when the speed of an airfoil doubles, the lift quadruples," explained Huff. "We knew that we could reduce the area of the rotors by 75 percent when we doubled the speed. Take Yuri I for example, which had eight rotors all rotating at approximately 20 RPMs. If they had been able to double the RPMs to 40, then they could have eliminated six rotors or 75 percent of their rotor area."

"However, any aerodynamicist will inform you that drag also quadruples when the speed of airfoil doubles so there would be much more drag, which is completely true," he continued. "So we knew that our primary focus had to be to reduce the drag of the rotors (other teams are focused on reducing the power required by increasing the span of the rotor, which allows them to reduce the speed of the rotor needed to lift off of the ground). By using smaller rotors rotating at 60+ RPMs we knew that our rotors had to be as efficient as possible. So our efforts over the past two years have been to design the most efficient rotors that we possibly could without relying on previous designs or foregone conclusions about how a rotor should be designed."

Huff and the team now feel that they have developed one of the most efficient rotors ever designed, but have not been able to fully test it due to a lack of funds. They have another grant request in with the College, but impatience has got the better of them and they've headed to Kickstarter to both generate interest in the project and hopefully provide the cash injection needed to get their human-powered helicopter off the ground.

Though rotor testing has produced positive results, the simple aluminum frame topped by a pair of two-bladed rotors has yet to make it into the air. The maximum lift generated so far is 80 pounds (36 kg), while the minimum lift needed to get the craft to fly has been calculated at 240 pounds (109 kg).

"There is much more uncertainty about the feasibility our rotor design because it runs contrary to the design of all other successful human-powered helicopters," said Huff. "This uncertainty is compounded when coupled with the fact that we have been working on it for two years and have yet to have a successful flight. Furthermore, some aerodynamicists and human-powered helicopter enthusiasts may swear to the impossibility of our design but we believe that there is always room for improvement in any design and truly believe that practical human-powered vertical flight is possible and has the potential to one day be a recreational activity similar to hang-gliding, and we hope to prove it."

The developers are convinced that, with funding, the helicopter will be capable of lifting 300 pounds (136 kg) using 300 watts or less of power ? a fraction of that needed by other Sikorsky contenders. Direction of the current model will be controlled by shifting the weight of pilot, but plans are afoot for a cyclic control system that should offer more precision.

Kickstarter backers can pledge support for the project in return for various rewards (including framed posters, a 48-page book or a brass S1223 airfoil cutout), or can take a giant leap of faith and promise $10,000 or more, which will secure a fully functional, full-scale replica of the finished helicopter.

In the event of another team beating Huff and friends to the elusive Sikorsky Prize ? which requires a craft to stay in the air for 60 seconds, stay within a 10 meter (32.8 ft) square and rise to three meters (9.8 ft) at some point during the strictly human-powered flight ? development on the project will continue.

The Kickstarter pitch video is below.

More transparency and doctor-hospital cooperation in implant component purchases could reduce overall spinal implant costs

CHICAGO In a study, presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), researchers obtained and compared the hospital purchasing records from 45 academic medical centers on the unit costs and volume of spinal products pedicle screws (PS), anterior cervical plates (ACP) and posterior interbody cages purchased from a total of seven vendors.

Among the results:

  • PS had a mean cost of $878, with a range of $400 to $1,843 per patient;
  • ACP had a mean cost of $1,068, with a range of $540 to $2,388; and,
  • cages, $2,975, with a range of $938 to $7,200

For every additional implant component purchased, the unit price was reduced by $.29, $4.33 and $6.86 for PS, ACP and cages, respectively.

A significant relationship exists between a lower unit cost of implants and the purchase of a larger number of components. The authors suggest that greater transparency, as well as a more coordinated implant selection and purchase process, that includes the surgeon, hospital and manufacturer, could reduce the wide variation in component cost, and contribute to overall lower health care expenditures.

Serotonin Receptors Offer Clues to New Antidepressants

Long-sought specificity on the shapes of serotonin binding sites could aid in the discovery of new drugs to combat depression, as well as in the study of consciousness


serotonin and ergotamine Two studies have decoded the structure of two of the brain's serotonin receptors. Here shown is a receptor known as 1B with the migraine drug ergotamine (pink) locked into one of its binding pockets. Image: Chong Wang & Huixian Wu

Researchers have deciphered the molecular structures of two of the brain's crucial lock-and-key mechanisms. The two molecules are receptors for the natural neurotransmitter serotonin ? which regulates activities such as sleep, appetite and mood ? and could provide targets for future drugs to combat depression, migraines or obesity.?

?This is huge,? says Bryan Roth, a neuropharmacologist at the University of North Carolina Chapel Hill Medical School, and a co-author of the two studies published in Science today. ?Before this there was no crystal structure for any serotonin receptor. A lot of what was theoretical is now known with a great degree of certainty,? he says.

Scientists have been trying to decipher serotonin receptors for years. Armed with information on the atomic level, they might now be able to make breakthroughs in drug discovery and in understanding how the physical structures of the brain produce consciousness, says Roth.

Christoph Anacker, a neuropharmacologist at King's College London, agrees that the findings are important for drug discovery. ?These receptors are involved in so many conditions, especially depression, and knowing the molecular structures will help to develop more specific drugs and avoid the expression of undesired side effects.?

Chemical messengers
There are 14 different known serotonin receptors. The molecules lie on the outer membranes of nerve cells; when drugs or neurotransmitters lock into the receptors from outside the cell, they trigger the release of other chemicals inside the cell. Those chemicals ? which can be different depending on what drug or neurotransmitter has triggered them ? activate further hormones and metabolites, producing signaling cascades that are ultimately responsible for many aspects of the way we feel, perceive and behave.

Some drugs bind at more than one receptor, setting off not-fully-understood reactions that can produce unwanted side effects. To avoid this, researchers want to fine-tune drugs so that they activate only the desired signaling pathway.

Roth and his colleagues uncovered the receptor structures using X-ray crystallography, in which X-ray beams are fired at crystals of the compound, and the structure is deduced from how the beams scatter.

The teams focused on two receptors, called 1B and 2B. They found that the molecules had very similar structures in the areas where serotonin docks.

But in one area of the 1B receptor, the binding pocket was wider than in the 2B receptor. Although the difference was a mere 0.3 nanometers, about the width of three helium atoms, the difference is enough to explain why the two receptors bind differently to certain compounds.

This distinction may be relevant to drug safety: some drugs that activate the 2B receptor have been thought to cause heart problems, and have been withdrawn as unsafe. The connection has earned the 2B the nickname of death receptor.

Are you a one percenter? Many were surprised to ... - Financial Post

If you reported income of over $201,400 in 2010, you were part of the top 1% of Canadian income earners. This cohort earned 10.6% of Canada?s total reported income that year and paid 21.2% of all personal taxes. The top 10%, whose income was at least $81,200 that year, accounted for 55% of the total personal tax collected in 2010.

These figures surprised many Financial Post readers last week, many who seemed shocked to find that they were in fact one percenters. Readers had numerous questions, and even some answers, as to what?s behind these numbers. Today Jamie Golombek digs deeper to find the answers.

????????

How much tax do the top 1% actually pay?

To enter the top 1% club, your reported 2010 income had to be at least $201,400. At this level of income, ignoring for a moment any tax credits beyond the basic personal amount, you would have paid about $81,000 of combined federal and provincial taxes if you lived in Quebec, $74,000 if you lived in Ontario, $69,000 in B.C. and a mere $65,000 if you were a resident of Alberta. (see Chart) These translate into effective tax rates of 40.1%, 36.7%, 34.3% and 32.4% respectively.

These effective average rates are the result of our graduated, progressive tax system which imposes a progressively higher tax rate on each dollar of taxable income above a certain threshold both federally and in all provinces other than Alberta, which has a 10% flat tax. So while an Ontario resident?s combined federal and provincial marginal tax rate may be 46.41% once income reached $127,000 (in 2010), the graduated brackets leading up to this threshold lower that effective rate to 36.7%.
Of course, even these average effective rates are likely somewhat overstated since they fail to take into account the myriad tax credits available for everything from public transit to charitable donations.

___
Do capital gains, which are earned disproportionately by the wealthiest of Canadians, play a large role in these numbers?

Not really. In fact, the numbers above exclude capital gains in the determination of the income thresholds. If we were to use total income including capital gains to determine the top 1% of tax filers, the threshold would be only slightly higher at $215,800.

_____
Wouldn?t the income reported and the tax payable by the top 1% be even higher if the rich didn?t take advantage of all those tax deductions and credits?

Maybe a little, but not as much as one might think. If we examine detailed 2010 income tax return data from the Canada Revenue Agency, we can zero in on tax filers who made $250,000 and over, which would be the top 0.7% of income earners. These 186,520 individuals reported a collective total income of $104-billion, claimed $12-billion in various tax deductions, including $2.9-billion in RRSP deductions and $1.2-billion in carrying charges and interest expenses, for a total reported taxable income of $92-billion.
The tax payable on this income was $20.7-billion federally, after deducting $1.1-billion in federal non-refundable tax credits, more than half of which were in respect of charitable donations. Add in another $9.2-billion of provincial and territorial tax for a total tax bill of roughly $30-billion.

_____

What about Canadians who just file returns to collect government benefits but pay no tax at all ? doesn?t that skew these numbers?

It does. Of the 25 million returns filed in 2010, the CRA reports that 8.4 million of them were non-taxable. Taking a look at the non-taxable returns, 96% of them were from individuals who reported under $25,000 in income.
The fact that one third of tax returns filed had no tax payable would explain why the top 1% of filers contribute so much to the collected tax.

??????
You only looked at personal income taxes, but what about other taxes, like corporate income taxes, or the GST/HST?

Personal taxes make up nearly 50% of government revenues and as such constitute, by far, the largest source of tax monies. By contrast, corporate income taxes account for 13% of revenues with the GST/HST contributing 11%.
