Two Rutgers physics professors have proposed an explanation for a new type of order, or symmetry, in an exotic material made with uranium ? a theory that may one day lead to enhanced computer displays and data storage systems and more powerful superconducting magnets for medical imaging and levitating high-speed trains.
Their discovery, published in this week's issue of the journal Nature, has piqued the interest of scientists worldwide. It is one of the rare theory-only papers that this selective publication accepts. Typically the journal's papers describe results of laboratory experimentation.
Collaborating with the Rutgers professors was a postdoctoral researcher at Massachusetts Institute of Technology (MIT) who earned her doctorate at Rutgers.
"Scientists have seen this behavior for 25 years, but it has eluded explanation." said Piers Coleman, professor in the Department of Physics and Astronomy in the School of Arts and Sciences. When cooled to 17.5 degrees above absolute zero or lower (a bone-chilling minus 428 degrees Fahrenheit), the flow of electricity through this material changes subtly.
The material essentially acts like an electronic version of polarized sunglasses, he explains. Electrons behave like tiny magnets, and normally these magnets can point in any direction. But when they flow through this cooled material, they come out with their magnetic fields aligned with the material's main crystal axis.
This effect, claims Coleman, comes from a new type of hidden order, or symmetry, in this material's magnetic and electronic properties. Changes in order are what make liquid crystals, magnetic materials and superconductors work and perform useful functions.
"Our quest to understand new types of order is a vital part of understanding how materials can be developed to benefit the world around us," he said.
Similar discoveries have led to technologies such as liquid crystal displays, which are now ubiquitous in flat-screen TVs, computers and smart phones, although the scientists are quick to acknowledge that their theoretical discovery won't transform high-tech products overnight.
Coleman, along with Rutgers colleague Premala Chandra and MIT collaborator Rebecca Flint, describe what they call a "hidden order" in this compound of uranium, ruthenium and silicon. Uranium is commonly known for being nuclear reactor fuel or weapons material, but in this case physicists value it as a heavy metal with electrons that behave differently than those in common metals.
Recent experiments on the material at the National High Magnetic Field Laboratory at Los Alamos National Laboratory in New Mexico provided the three physicists with data to refine their discovery.
"We've dubbed our fundamental new order 'hastatic' order, named after the Greek word for spear," said Chandra, also a professor in the Department of Physics and Astronomy. The name reflects the highly ordered properties of the material and its effect on aligning electrons that flow through it.
"This new category of order may open the world to new kinds of materials, magnets, superconductors and states of matter with properties yet unknown," she said. The scientists have predicted other instances where hastatic order may show up, and physicists are beginning to test for it.

It seems that after bankrupt radio voice Tom Martino insisted that his non-profit Make It Right Foundation company is not a charity, the Colorado secretary of state?s office says it is a charitable organization after all.
The organization Martino incorporated in 2009 raises money, he says, to help people in need of assistance, many of them affected by the companies he does battle with on his show. As Martino puts it: ?We simply want a vehicle for collecting and distributing money to the needy.?
That?s a good thing.
But Martino?s non-profit corporation ? not the 501(c)3 Make It Right Foundation that actor Brad Pitt founded in order to help rebuild New Orleans following the devastation of Hurricane Katrina in 2005 ? does not file non-profit tax forms, known as 990s, as other more-common charities do and which are by law available for public inspection. The Denver Post?s Season to Share is another example.
Nor does it file the Form 990PF, which is for private foundations.
That?s because MIRF doesn?t have to. It falls in the tiny space of non-profit companies that are not tax-exempt groups, are not foundations by the IRS definition, and whose contributions are not deductible, either.
?I chose to simply have a private non-profit corporation to have complete freedom with how we use the money,? Martino said. ?If I wanted to help someone who was ripped off one day, and then help someone who simply was ?down on their luck? the other day, I could do this without worrying about violating any principals.?
Martino said the funds come from his own pocket, from friends, listeners and sponsors of his show. The Post reported some also was to come from attendees to a financial seminar he was a part of, according to its organizers.
?I can do anything I want with my money,? Martino wrote in an email to The Denver Post when asked about the non-profit and why there was no public disclosure of its finances. ?And I can do anything I want with money from friends and listeners who trust me. It is that simple. It is private. It is none of your business.?
Elsewhere, Martino explains it clearly: ?Do not contribute unless you trust us.?
Federal tax authorities say a non-profit corporation that raises money doesn?t have to disclose its tax records to the public if it is not tax exempt, such as a 501(c)3 would be required to do.
So why wouldn?t all non-profits do it this way? Because it would be difficult to raise money, is what the pros said.
Last month, though, the Colorado Secretary of State?s office of charitable solicitations, the guys who track charities and the solicitation campaigns that are run in the state, contacted Make It Right to say it probably needed to register as a charitable organization and as a charitable solicitor, even though it?s not a tax-exempt group, program officials said.
Why? Because MIRF raises money ? albeit in a limited manner and amount ? for the benefit of others, though no one could take a tax deduction for the donation, and Martino is clear that they can?t. Certain state laws fall into place requiring the public disclosure of a charitable campaign, how much money it raised and how much was used toward a stated charitable purpose.
This way the public has a way to go online and research for itself any organization it?s considering for a donation, ostensibly to see if it?s the best use of their dollar.
So, to Martino?s credit, Make It Right registered in early December 2012, as a charitable organization that can solicit contributions. It even has a nice legal registration number, though it still doesn?t have to file the federal IRS Form 990 required of other charities because it is still not tax exempt. Martino has said its taxes are properly filed in other non-public documents and he doesn?t want tax-exempt status.
I got no response from Tom to an email I sent him the past few days asking about the registration, and his attorney says Tom?s a ?hurting puppy? these days, recovering from knee surgery, an ear infection, and the bankruptcy case around his neck.
?He does not want to play with you any more,? his attorney, Stephen Berken, wrote in an email.
Anyway, MIRF last year raised $7,518.63 for ?civil rights, social action and advocacy, education and human services,? according to its first financial statement filed with the state.
Of that amount, it appears about $4,000 came from The Melting Pot restaurant in Littleton, based on a pair of YouTube videos that have been circulated showing their in-studio donation to Martino.
Make It Right had $8,602.50 in program services, meaning that?s how much it says it paid to help people. Who got helped and in what manner is information not required to be listed on the document.
As Martino has asserted, 100 percent of everything they collected went out the door ? actually more than they reportedly collected ? and MIRF had no expenses and no one made any money at the end of the year, according to the filing.
Unclear is whether the state will require filings from prior years, which it has the right to request.
Now, just like any other charitable solicitation organization in Colorado ? regardless if it?s a tax-exempt charity or not ? you can look it up for yourself.
Or take a look here.

WASHINGTON (AP) ? The number of veterans who commit suicide each day is more than 20 percent higher than the Department of Veterans Affairs has previously estimated, but the problem doesn't appear to be getting worse for veterans compared to the rest of the country, according to a VA study released Friday.
Indeed, the overall percentage of suicides by veterans has declined in recent years. VA researchers say the trend suggests that efforts to reduce suicide among veterans may be having an effect.
About 22 veterans committed suicide each day in 2010. Previous estimates from the VA put the number at 18.
While much attention has been paid to suicides by veterans of Iraq and Afghanistan, the report indicates the problem is worse among older veterans. About 70 percent of veterans who commit suicide are over age 50.
The latest projections from the VA incorporate data from about two dozen states that recorded the cause of death on death certificates. Previous estimates focused only on those getting care from the VA's hospitals and clinics. The department described the study as the most comprehensive it has ever taken on the issue.
"We have more work to do, and we will use this data to continue to strengthen our suicide prevention efforts and ensure all veterans receive the care they have earned and deserve," said VA Secretary Eric K. Shinseki.

As unbelievable as it may seem, the Buffalo Bills have yet to start serious negotiations on a contract with their reliable left guard Andy Levitre and now he will look to test the free agency waters.
Since being drafted in the second round of the 2009 NFL Draft, Levitre has started 64 consecutive games, an impressive beginning to a blossoming career, but it gets better. During that same time period, he did not miss a single snap. He was the one constant on a Bills front line that was often ravaged by injury. What is the Bills loss will undoubtedly be another NFL team?s gain and one such candidate will undoubtedly be the Miami Dolphins.
The Bills were sixth in the league in rushing and they were 10th best in the league against the sack, giving up a total of 30. The Dolphins were 20th, giving up 37, and were 17th in rushing.
The Dolphins? offensive line was a work in progress throughout the 2012 season and will likely look very different when training camp wraps up this fall. The biggest questions at the moment surround left tackle Jake Long. Long also enters free agency in March, but his season ended early due to injury and his performance throughout the season was less than what the football world has come to expect from the four-time Pro Bowl-er.
NFL Rumors are now claiming that Long is asking for more than the Dolphins will be willing to pay and that the team feels comfortable plugging Jonathan Martin into the left tackle spot. If they do make this move, then it would also make sense to try and shore up the right side of the line.
One way they could strengthen the right side would be by bringing Levitre in and moving current left guard Richie Incognito over to the right. Incognito had an interesting year, being named one of the dirtiest players in the NFL as well as being selected to represent the team at the Pro Bowl.
In the past, Incognito has played the right guard and has said he is even more comfortable at that position, giving the Dolphins coaching staff the flexibility it takes to put together that magic line-up.

These days it seems that you can?t talk about doing business online without talking about mobile connectivity as well. The two are becoming more intrinsically linked, as smartphones and tablets bring the internet with us wherever we go. And as the latest Australian Mobile Phone Lifestyle Index (AMPLI) survey results show, the rise of mobile connectivity does not look like slowing any time soon.
AIMIA, the Digital Industry Association of Australia, has been running the AMPLI survey for eight years to gauge a better understanding of how Australians are using mobile phones.? Given that the iPhone had not even been launched eight years ago, you can imagine how dramatically the survey results have changed over the years. Over 3,000 mobile phone owners participated in the 2012 survey.
According to the 2012 survey results 76% of respondents had a smartphone, up from 67% the previous year. Based on the purchase intentions of mobile phone owners, it appears this is likely to increase to 84% by the middle of this year.
The iPhone leads the mobile handset market, owned by 40% of respondents (up from 32%). The report also found that Samsung mobile phones are becoming more popular, rising from 13% to 18%, while Nokia recorded a significant drop, from 28% to 16%.
The mobile phone is clearly about more than standard calling and texting in our modern world. The survey found that in 2012 79% of respondents were getting information online, 76% were visiting websites or searching online, 72% were using their mobile phone for entertainment purposes.? Further, 69% were emailing on their mobile phone and 42% bought things online.
Nearly one third of respondents (31%) checked their email on their mobile phone at least five times a day, while 25% visited websites or did online searches at least five times a day. Overall, 17% of respondents used their mobile phone to buy things online at least once a week.
It appears that mobile phones are also increasingly being used to help inform consumers? purchasing decisions. The survey revealed that 38% of respondents use their mobile phone to check prices and that 43% use it to check reviews before making a purchase decision.
The majority of AMPLI survey respondents used a mix of apps and websites on their mobile phones. A very small proportion used apps only (4%) or websites only (8%). While the majority of respondents had downloaded six or more apps on their phone in the six months before the survey (71%), most respondents only use five or less apps on a weekly basis (60%).
Most respondents indicated that they accessed websites by typing the URL directly into the browser on their phone (75%). However, 68% also clicked on links provided in search engine results and 48% clicked on links in text messages.
While 40% of respondents had opted in to receive SMS or MMS messages from 1-5 businesses, 43% were not receiving any SMS or MMS advertising.
Around a quarter of respondents had engaged with vouchers or coupons sent to their mobile phone (26%), or with banner/text ads in websites (26%) and apps (25%). When it came to social media, 24% had engaged with ads or messages about a business via Twitter or Facebook.
There are a lot of statistics here (and more in the report), providing plenty of food for thought for Australian businesses. With around 4 in 5 mobile phone owners using their mobile phone to get information, visit websites or perform searches ? many multiple times a day ? it appears to be more important than ever that your business has some form of online presence to maximise your chances of being found. The trends over the last few years show that consumers are also becoming more and more comfortable shopping and doing other transactions online.
When it comes to the question of whether businesses should have a mobile-friendly website or an app, the survey shows that mobile phone users are engaging with both. But if you are going to invest in an app, it is a good idea to ask yourself what you can do to make sure your app is one of the five that the average mobile phone owner engages with regularly.
And while it seems that a relatively low proportion of consumers are engaging with other forms of advertising, such as SMS and MMS messages, the trend over the last few years appears to show that consumers are becoming increasingly willing to connect with businesses through these forms of advertising.
Have you had success engaging with customers through their mobile devices? Or are you considering addressing mobile in your business strategy? Share your thoughts and experiences with us.
