Brand new bonding skills make boron more like carbon

BORON has been hiding secret skills but its cover is finally blown.

In a tightly sealed flask in a German lab sits an emerald-green crystal that is the first stable compound with a triple chemical bond between two boron atoms. Such bonds were previously reserved for an elite club of atoms, including carbon, which sits next to boron in the periodic table.

In another first, boron atoms have linked up with each other in chains. Carbon's tendency to do so is the basis for organic chemistry, making possible DNA, proteins, alcohols and plastics. Synthetic, or alien, life based on boron remains far-fetched - boron still can't link to other life-related compounds, for one thing. But the feats pave the way for boron-based polymers, and other structures previously undreamed of. "Certainly this will go into the textbooks," says Holger Braunschweig of the University of W?rzburg in Germany.

Until now largely obscure, boron occupies a special spot in the periodic table. On one side are metals like beryllium, which give away their outermost electrons to form ionic bonds. On the other side are the non-metals carbon and nitrogen, which prefer sharing electrons in covalent bonds.

A single covalent bond is two electrons shared between two atoms. Carbon, with four outer electrons, and nitrogen with five, form triple covalent bonds consisting of six shared electrons, or three pairs. Boron has three outer electrons, so in principle should be capable of this too, but it has remained aloof. In 2002, Mingfei Zhou and colleagues at Fudan University in Shanghai, China, managed to make a boron triple bond - but only at 8 degrees above absolute zero.

Boron can hold up to eight outer electrons: a pair in each of four slots. In atomic boron, one of these slots is completely empty and the other three are half-full, with one electron apiece. To make triple-bonded boron that could survive at room temperature, Braunschweig and his colleagues filled all four slots. They filled up the empty slot by bonding each boron atom to a molecule that donated two electrons. Each boron atom then completed the filling of its slots by pairing up with another boron atom and pooling its original three electrons (see diagram). In the resulting compound, each boron atom has a full suite of eight outer electrons, making it stable (Science, DOI: 10.1126/science.1221138).

Braunschweig and his team have already begun investigating the reactivity of the novel compound. "It turns out that it shows a rich chemistry," he says.

Triple-bonding is not the only way the researchers got boron to mimic its superstar neighbour, carbon, though. They also coaxed boron atoms into forming a chain. Previous attempts to do this with boron failed and resulted in messy clusters. "It is extremely difficult to form chains of boron atoms," says Braunschweig. The secret was to attach the boron atoms to an iron scaffold, which allowed up to four to form a chain (Nature Chemistry, DOI: 10.1038/nchem.1379).

Next, Braunschweig and his team hope to free this boron chain from its scaffold and increase the chain length to form the boron equivalent of polyethylene, a common plastic. "The material, if it could be made, would have completely different physical behaviour from an ordinary carbon chain," Braunschweig says.

A world of previously forbidden chemistry beckons. "They did not simply find a new flower or a new plant," says Gernot Frenking of the University of Marburg in Germany, who was not involved in the work. "They opened the door to a whole new garden."

Fan Claims Amar?e Stoudemire Called Him a ?Fag? Via DM on Twitter (Photos)

Quick Twitter 101 lesson.

If you are following someone they can send you a private Direct Message, but you can?t reply to it. It comes in handy for athletes and entertainers who like to respond to people, but don?t want it on their public timeline or want to get into a lengthy discussion.

For instance Skip Bayless DMs a lot of people, but no one can DM him back because he only follows one person.? The reason I know this is people send me copies of the DMs all the time.? Relax, he is just talking like Skip, nothing to see here.

So, what you are about to see is totally plausible.

Considering the time between the Tweets and the fact that @BFerrelli didn?t really say anything that bad, I tend to believe that Amar?e sent this DM.

If that is the case that makes Amar?e softer than Drake sending love notes to Chris Brown.

Be a man, if you want to call him a ?Fag?, don?t be scared do it in public where the world can see. Furthermore, how much of any idiot can you be in 2012 to do something like that and think the guy wouldn?t screenshot it?

Once again if Amar?e did this he isn?t only being soft, he is also a Moron and history shows he is certainly capable of being both.

*UPDATE*

More fans are coming about to talk about Amar?e DM foul messages.

Technology: Surface tensions | Nicosia Business Review Worldwide ...

Microsoft Apple tablet

The pile of tablet computers that have abjectly failed to match the delights of the iPad has been growing steadily over the past two years. It includes defunct devices like Hewlett-Packard?s TouchPad and Cisco System?s Cius, as well as struggling pretenders such as Motorola?s Xoom and Samsung?s Galaxy Tab.

Whether the Surface ? the tablet unveiled by Microsoft this week ? will one day be cast on to the scrapheap of failed electronic dreams is a question set to assume outsized importance in the war being waged over the future of personal computing.

Due to go on sale later this year, the Surface is Microsoft?s first attempt at making its own personal computing device, and the biggest gamble so far in its attempt to avoid a future of technological irrelevance. It is also a mark of how deeply Apple?s success, first with the iPhone and now with the iPad, is transforming the tech world. A once-feared monopolist whose grip on computing seemed unshakeable has been forced to change course. In the world of personal computing, nothing will be the same again.

Its slick magnesium body and thin cover that also acts as a touch-sensitive keyboard have already won the Surface rare plaudits in a market spoilt by the design genius of Apple. But there is far more at stake here than the fate of a single gadget might suggest. Thanks to Apple, personal computing has broken free of the stolid desktops and ?clamshell? laptops of the past and migrated to the touch-sensitive screens of tablets and smartphones.

Microsoft has finally adapted to the business practices of its nemesis as it tries to follow. ?This is critical for [Microsoft] in the long term,? says Rick Sherlund, software analyst at Nomura. ?It?s time they got in the game, this is where all the growth is.? The alternative: to be consigned to a quiet backwater of computing where PCs become simply the unloved workhorses of corporate life.

The Surface represents a fundamental change in the methods that Microsoft has deployed up to now to rule the PC World. Most strikingly, the world?s biggest software company has entered the business of making personal computing devices ? though given the realities of the modern, globalised electronics supply chain, that means contracting out assembly of its tablet design to a manufacturer in Asia rather than operating its own factories.

While it has not previously attempted to sell its own personal computers, Microsoft has at least ventured into hardware before through devices such as the Xbox gaming console and the Zune music player. These businesses have had mixed success, but they have left Microsoft with a deeper understanding of hardware than might be expected of a company that has dominated the software industry, including 3,200 patents on hardware inventions.

By also taking a leaf out of Apple?s book of savvy publicity and stoking anticipation ahead of this week?s announcement, Microsoft was able to secure a stronger reception for the Surface in the tech world than might normally be expected for a company that seldom arouses strong consumer sentiment. Some commentators even suggested that this is the closest any rival has come to matching Apple?s tablet thanks to the Surface?s innovative cover, a built-in kickstand that lets it stand more easily than the iPad, and a widescreen format that makes it more appealing to scroll horizontally through content.

Playing second fiddle to the iPad, however, is not a comfortable place for any hardware maker to be. With about two-thirds of the booming
tablet market this year, according to research company IDC, Apple?s tablet has seen off pretenders and left its rivals fighting over the scraps.

In its pursuit of Apple, Microsoft has also trodden on the toes of its closest allies ? PC makers like Hewlett-Packard, Dell, Acer and Lenovo. With growth in PC sales sluggish at best, these companies have looked to Microsoft?s forthcoming Windows 8 operating system, which is designed for touchscreen computing, to open new markets such as tablets for them. Now they will find some of their toughest competition coming from Microsoft itself.

Steve Ballmer, Microsoft chief executive, sought this week to play down the change, claiming that the company had habitually stepped into hardware when it needed to demonstrate the potential of its software ?in ways the makers of hardware themselves had yet to envision?. Microsoft and its allies, he added, were always ?pushing each other and pulling each other forward?.

Yet there is more to the Surface than this suggests. The new tablet market is simply too important for Microsoft to entrust entirely to others. With other hardware makers having failed so far to come up with an effective rival to the iPad, it has had to take matters into its own hands. ?They needed to take out some insurance,? says Mr Sherlund.

Microsoft?s readiness to move beyond the approach that has underpinned its prosperity also hints at another powerful new consideration: that the financial model for success in personal computing is changing.

The software company was once happy to sit back and skim the cream from the PC business, earning high profits from software as its partners struggled to make a living in the cut-throat PC hardware world. This way may no longer be the most effective.

In the latest quarter, Apple?s profit margins topped those of Microsoft for the first time in the companies? three-decade rivalry, giving the lie to the industry?s conventional wisdom that hardware makers will always be less profitable. It is now Apple that is in a position to suck the profits out of personal computing ? and on a scale that even the mighty Microsoft would once barely have dreamt of.

This is producing a transfer of industry leadership that is happening with dizzying speed ? even by the standards of the tech world. As little as three years ago Microsoft boasted sales that were 60 per cent higher than those of Apple and operating income that was more than 160 per cent greater. By the first quarter of this year that position had flipped. Thanks to soaring sales of the iPhone and iPad, Apple?s revenues are now 125 per cent greater than those of Microsoft, while its operating income is 140 per cent higher.

The distinction of owning the world?s most pervasive computing platform is also under threat. As Mr Ballmer boasted this week, there are some 1bn PCs in use running versions of his company?s Windows operating system. That compares with more than 350m of the iPhones, iPads and iPod touches that run Apple?s iOS operating system, which was launched five years ago. But with sales of Apple?s devices doubling in the first quarter of this year, that position is shifting quickly.

This has already started to starve Microsoft of something critical to its success: the attention of the most creative software developers, whose applications ultimately account for the appeal of general-purpose computers such as PCs and tablets. Among the latest generation of developers, attention has already passed to the fast-growing world of mobile apps ushered in by Apple?s App Store.

The Windows world is populated by developers who are generally older and do not have experience writing applications for the mobile devices that are taking over, says Marten Mickos, an open source software entrepreneur.

?The PC is pass? ? it?s not where the fancy stuff is happening,? adds Doc Searls, an American technology writer and academic.

That helps to explain Microsoft?s attempt this week to whip up excitement for the Surface long before it is ready to go on sale, and even before important technical and pricing details have been revealed. The competition for the hearts and minds of developers is only set to get fiercer: next week it is Google?s turn to hold its annual conference for developers and rumours are rife that it will also announce plans to enter the tablet hardware business for the first time.

For the Surface to have any chance in this battle, Microsoft must pull off two feats. One will be to come up with enough original content and services for its tablet to persuade customers that it is more than just a pale imitation of the iPad. As the discontinued Zune showed, having well-regarded hardware is not enough on its own to break into a market against an entrenched leader.

The other feat will be to find a new niche for the Surface between the current PC and tablet worlds ? one where users can type and run full-scale business applications, as they are used to doing on their PCs, while also leaning back and reading books or watching videos, as they may prefer to do on an iPad. With its touch-sensitive keyboard cover and kickstand, the Surface can quickly be turned into a device that resembles a laptop ? though whether users will take to a machine that tries to span two different approaches to computing is another matter.

Apple and other Microsoft enemies have been claiming for some time that the ?post-PC? era is at hand. The fate of the Surface may well show whether they are right.

(AP) ? A Syrian fighter pilot on a training mission flew his MiG-21 warplane to Jordan on Thursday and asked for political asylum, the first defection of an air force pilot with his plane during the 15-month uprising against President Bashar Assad.

The air force is considered fiercely loyal to Assad's regime, and the defection suggests some of Syria's most ironclad allegiances are fraying. It was a triumph for the rebels fighting to overthrow Assad. A spokesman for the rebel Free Syrian Army, Ahmad Kassem, said the group had encouraged the pilot to defect and monitored his activity until the jet landed safely in Jordan.

The pilot, identified as Col. Hassan Hammadeh, removed his air force tag and kneeled on the tarmac in prayer after landing his plane at King Hussein Air Base in Mafraq, Jordan, 45 miles (70 kilometers) north of Amman, a Jordanian security official said.

He said Jordanian official were questioning the defector, but he will be allowed to stay in the country on "humanitarian grounds."

"He was given asylum because if he returned home, his safety will not be guaranteed. He may tortured or killed," the official said. He declined to say what Jordan will do with the jet. The official insisted on anonymity, citing the sensitivity of the matter.

Syria's state-run TV reported earlier in the day that authorities had lost contact with a MiG-21 that was on a training mission in the country. After it became clear the pilot had defected, the state-run news agency quoted an unnamed military official as saying he was "a traitor to his country and his military honor."

Jordanian Information Minister Sameeh Maaytah confirmed that the pilot had defected.

The defection is a sensitive issue for Jordan, which wants to avoid getting dragged into the Syrian conflict. Jordan already has taken in 125,000 Syrian refugees, including hundreds of army and police defectors, and Syria is seeking their return.

Syria is one of Jordan's largest Arab trade partners, with bilateral trade estimated at $470 million last year.

The Syrian regime has been hit with defections before, although none as dramatic as the fighter pilot's. Most have been low-level conscripts in the army.

In March, however, Turkish officials said that two Syrian generals, a colonel and two sergeants had defected from the army and crossed into Turkey. Also in March, Syria's deputy oil minister became the highest-ranking civilian official to join the opposition and urged his countrymen to "abandon this sinking ship" as the nation spiraled toward civil war.

Brig. Gen. Mostafa Ahmad al-Sheik, who fled to Turkey in January, was the highest ranking officer to bolt. In late August, Adnan Bakkour, the attorney general of the central city of Hama, appeared in a video announcing he had defected.

In January, Imad Ghalioun, a member of Syria's parliament, left the country to join the opposition saying the Syrian people are suffering sweeping human rights violations.

Obama revels in support from Latinos, swipes Romney

LAKE BUENA VISTA, Florida (Reuters) - President Barack Obama reveled in the support of Latino leaders on Friday and took a swipe at his election rival Mitt Romney for giving mixed messages on how to handle illegal immigration.

In an emotive speech to Hispanic public officials meeting in Florida, Obama reminded the friendly audience that Romney had promised to veto the DREAM Act, which would help the children of illegal immigrants win citizenship.

Obama told the National Association of Latino Elected and Appointed Officials conference that he chose last week to halt the possible deportations of 800,000 young illegal immigrants because Congress was stalling on the issue.

"I refused to keep looking young people in the eye, deserving young people in the eye, and tell them tough luck," he said, receiving a standing ovation from the crowd that gave Romney a cool reception the day before.

"Your speaker from yesterday has a different view. In a speech he said that when he makes a promise to you, he'll keep it. Well he has promised to veto the DREAM Act, and we should take him at his word," the Democratic president said.

"I'm just sayin'," he added, to laughter.

A poll released on Friday by Latino Decisions and America's Voice found Obama had a commanding lead over Romney among Hispanics in election battleground states including Florida, Colorado and Virginia.

In the five states combined, Obama leads Romney among Hispanics by 63 percent to 27 percent.

Obama's recent focus on immigration has helped perk up his campaign, which sagged earlier in June as economic bad news rolled in and the president committed a misstep by claiming that the struggling private sector was in fact doing fine.

A rise by former Massachusetts Governor Romney in the polls appeared to slow this week, although a Pew Research Center survey on Friday put Obama's lead at only 4 percentage points, from 7 points last May.

Romney's campaign suffered on Friday from new accusations about Bain Capital, where he made much of his $250 million fortune as a private equity executive in the 1980s and '90s.

The Washington Post reported that Bain invested in firms that specialized in relocating jobs done by American workers to new facilities in low-wage countries like China and India.

"(Romney) often says, ?I know why jobs come and why jobs go.' Well, yeah, one of the reasons they go is because you have firms who are counseling people on how to offshore and outsource their jobs, that's one reason they go, so, yeah, he knows a lot about it," Obama campaign adviser David Axelrod told reporters.

STANDING OVATIONS

Obama received standing ovations from much of the crowd in Florida when he talked about healthcare reform and his decision not to target young illegal immigrants for deportation.

"This was an Obama crowd anyway. Even though Obama's not Latino, he hit on key cultural points - hardworking, education. That's something we wear on our sleeves," said Tony Cardenas, a Democratic city councilman from Los Angeles.

Obama also pledged to make overhauling U.S. immigration rules to better serve businesses and make life easier for families and workers core to his economic agenda in a second term.

But Hispanics are still upset at his failure to deliver on comprehensive immigration reform and Latinos have been badly hit by the slow economy.

"No election-year speech can cover up the president's job-killing policies that have led to 11 percent Hispanic unemployment and millions of Hispanics living in poverty," Romney campaign spokesperson Amanda Henneberg said.

There are more than 50 million people with Latin American roots living in the United States. Hispanics are the fastest-growing U.S. minority group and could decisively influence the presidential election result in November.

Romney angered many Hispanics during the Republican primary season by saying illegal immigrants could "self deport" out of the country. He changed his tone at the NALEO conference on Thursday, stressing immigration was essential to U.S. economic prosperity, but offered few details on his approach to dealing with those now living illegally in the country.

A Hispanic former member of Senator John McCain's 2008 presidential bid acknowledged on Friday that Romney was going to struggle to win votes from the Hispanic community.

"Obama giving my Democrat colleagues a lot more to work with, than Romney gave me yesterday at #NALEO. It ain't going to be easy, folks," Ana Navarro, who was McCain's national Hispanic co-chairwoman, wrote on Twitter.
