Researchers build a working tractor beam, on a very small scale

We recently saw research that suggested negative radiation pressure in light could lead to a practical tractor beam. A partnership between the Czech Republic's Institute of Scientific Instruments and Scotland's University of St. Andrews can show that it's more than just theory: the two have successfully created an optical field that flipped the usual pressure and started pulling objects toward the light. Their demo only tugged at the particle level -- sorry, no spaceships just yet -- but it exhibited unique properties that could be useful here on Earth. Scientists discovered that the pull is specific to the size and substance of a given object, and that targets would sometimes reorganize themselves in a way that improved the results. On the current scale, that pickiness could lead to at least medicinal uses, such as sorting cells based on their material. While there's more experiments and development to go before we ever see a tractor beam at the hospital, the achievement brings us one step closer to the sci-fi future we were always told we'd get, right alongside the personal communicators and jetpacks.

Egypt's National Defence Council calls for dialogue

CAIRO (Reuters) - Egypt's National Defence Council, headed by President Mohamed Mursi, on Saturday condemned street violence and called for national dialogue to resolve political differences, the information minister said after the council met.

The council, which includes the defense minister, who is a general in charge of the army, could also consider declaring a state of emergency or a curfew in areas of violence if needed, Information Minister Salah Abdel Maqsoud said.

At least 39 people were killed in violence in Port Said on Saturday over a court ruling and across the nation during Friday's anti-Mursi protests.

The council called for "a broad national dialogue that would be attended by independent national characters" to discuss political differences and ensure a "fair and transparent" parliamentary election, the minister said in a televised statement.

Calls by the president and his government for national dialogue have been spurned in the past by the main liberal-minded opposition, who accuse Mursi and his allies of ignoring any opposing views.

The violence that first erupted on Thursday, the eve of the anniversary of a revolt that started on January 25, 2011, has highlighted the deep divisions in Egypt and cast a shadow over a parliamentary poll which could start in April.

Love triumphs over hate to make exotic new compound

Friday, January 25, 2013

Northwestern University graduate student Jonathan Barnes had a hunch for creating an exotic new chemical compound, and his idea that the force of love is stronger than hate proved correct. He and his colleagues are the first to permanently interlock two identical tetracationic rings that normally are repelled by each other. Many experts had said it couldn't be done.

On the surface, the rings hate each other because each carries four positive charges (making them tetracationic). But Barnes discovered by introducing radicals (unpaired electrons) onto the scene, the researchers could create a love-hate relationship in which love triumphs.

Unpaired electrons want to pair up and be stable, and it turns out the attraction of one ring's single electrons to the other ring's single electrons is stronger than the repelling forces.

The process links the rings not by a chemical bond but by a mechanical bond, which, once in place, cannot easily be torn asunder.

The study detailing this new class of stable organic radicals will be published Jan. 25 by the journal Science.

"It's not that people have tried and failed to put these two rings together -- they just didn't think it was possible," said Sir Fraser Stoddart, a senior author of the paper. "Now this molecule has been made. I cannot overemphasize Jonathan's achievement -- it is really outside the box. Now we are excited to see where this new chemistry leads us."

Sir Fraser is the Board of Trustees Professor of Chemistry in the Weinberg College of Arts and Sciences at Northwestern. In the late 1980s, he was one of the early pioneers to introduce an additional type of bond, the mechanical bond, into chemical compounds.

The new Northwestern compound has attractive electronic characteristics and can be made quickly and inexpensively. Down the road, it may be possible to expand this first linked pair into a longer chain-like polymer where this methodology could be useful in new technologies for batteries, semiconductors and electronic memory devices.

Driven by curiosity, Barnes only began to look at the radical chemistry of the ring cyclobis (paraquat-p-phenylene) two years ago, nearly 25 years after the ring was first made.

"I wondered what would happen if we took it all the way to the max," said Barnes, the paper's first author and a member of Stoddart's group. "Can we take two of these rings, each with four positive charges, and make them live together?"

The rings repel each other like the positive poles of two magnets. Barnes saw an opportunity where he thought he could tweak the chemistry by using radicals to overcome the hate between the two rings.

"We made these rings communicate and love each other under certain conditions, and once they were mechanically interlocked, the bond could not be broken," Barnes said.

Barnes' first strategy -- adding electrons to temporarily reduce the charge and bring the two rings together -- worked the first time he tried it. He, Stoddart and their colleagues started with a full ring and a half ring that they then closed up around the first ring (using some simple chemistry), creating the mechanical bond.

When the compound is oxidized and electrons lost, the strong positive forces come roaring back -- "It's hate on all the time," Barnes said -- but then it is too late for the rings to be parted. "That's the beauty of this system," he added.

Most organic radicals possess short lifetimes, but this unusual radical compound is stable in air and water. The compound tucks the electrons away inside the structure so they can't react with anything in the environment. The tight mechanical bond endures despite the unfavorable electrostatic interactions.

The two interlocked rings house an immense amount of charge in a mere cubic nanometer of space. The compound, a homo[2]catenane, can adopt one of six oxidation states and can accept up to eight electrons in total.

"Anything that accepts this many electrons has possibilities for batteries," Barnes said.

"Applications beckon," Stoddart agreed. "Now we need to spend more time with materials scientists and people who make devices to see how this amazing compound can be used."

NASA testing vintage engine from Apollo 11 rocket

HUNTSVILLE, Ala. (AP) ? Like vinyl records and skinny ties, good things eventually come back around. At NASA, that means looking to the Apollo program for ideas on how to develop the next generation of rockets for future missions to the moon and beyond.

Young engineers who weren't even born when the last Saturn V rocket took off for the moon are testing a vintage engine from the program.

The engine, known to NASA engineers as No. F-6049, was supposed to help propel Apollo 11 into orbit in 1969, when NASA sent Neil Armstrong and two other astronauts to the moon for the first time. The flight went off without a hitch, but no thanks to the engine ? it was grounded because of a glitch during a test in Mississippi and later sent to the Smithsonian Institution, where it sat for years.

Now engineers are learning to work with technical systems and propellants not used since before the start of the space shuttle program, which first launched in 1981.

Nick Case, 27, and other engineers at NASA's Marshall Space Flight Center on Thursday completed a series of 11 test-firings of the F-6049's gas generator, a jet-like rocket which produces 30,000 pounds of thrust and was used as a starter for the engine. They are trying to see whether a second-generation version of the Apollo engine could produce even more thrust and be operated with a throttle for deep-space exploration.

There are no plans to send the old engine into space, but it could become a template for a new generation of motors incorporating parts of its design.

In NASA-speak, the old 18-foot-tall motor is called an F-1 engine. During moon missions, five of them were arranged at the base of the 363-foot-tall Saturn V system and fired together to power the rocket off the ground toward Earth orbit.

Thursday's test used one part of the engine, the gas generator, which powers the machinery to pump propellant into the main rocket chamber. It doesn't produce the massive orange flame or clouds of smoke like that of a whole F-1, but the sound was deafening as engineers fired the mechanism in an outdoor test stand on a cool, sunny afternoon.

The device produced a plume that resembled a blow torch the size of two buses and set fire to a grassy area, which was quickly extinguished.

"It's not small," Case said. "It's pretty beefy on its own."

And just like during the Apollo days, people in north Alabama heard rockets thundering in the distance during tests at Marshall.

"My wife and daughter were in our front yard and she said they could hear it, which was pretty cool," Case said after an earlier test. "We live about 15 miles away."

A single F-1 engine can produce 1.5 million pounds of thrust using a fuel composed of liquid oxygen and refined kerosene, which was not used in the space shuttle.

The tests were conducted at Marshall in a project conducted with Dynetics Inc. and Pratt & Whitney Rocketdyne, which are studying NASA's possibilities for deep-space missions years from now. The space agency plans to use commercial launches to reach low Earth orbit; larger rockets are required to escape the planet's gravity.

R.H. Coates, an engineer who works with Case in Marshall's liquid propulsion office, said young engineers can learn a lot from the work done by predecessors using slide-rules in the 1960s, but no one wants to simply rebuild the old Saturn V engine.

"This wouldn't be your daddy's F-1," Coates said. "We'd use new materials and try to simplify it, update it."

Case started at Marshall as a high school intern in 2002 and has been working there since graduating from the University of Alabama in Huntsville in 2008. He said today's technology allows things that weren't possible during the 1960s, but he has been impressed by what he learned taking apart the unused Apollo 11 engine.

Engine No. F-6049 didn't fit properly on the Apollo 11 rocket, but it is invaluable now as a testing tool. Coates said a total of 85 F-1 engines were used on 17 Apollo flights without a single failure.

About a dozen F-1 engines remain in Huntsville, Ala., home of NASA's main propulsion center, and others are located elsewhere. Most are on display. Case said engineers used engine No. F-6049 for the tests because it was the most complete.

"It is really an excellent booster," he said. "The guys in Apollo had it right."

United Nations Security Council Condemns North Korea Rocket Launch

UNITED NATIONS -- The U.N. Security Council on Tuesday unanimously approved a resolution condemning North Korea's rocket launch in December and imposing new sanctions on Pyongyang's space agency.

The multi-stage rocket launch is considered part of a covert program to develop ballistic missiles that can carry nuclear warheads.

The council reiterated its previous demand that North Korea abandon its nuclear weapons program in a "complete, verifiable and irreversible manner" and cease launches.

China joined in approving the resolution, the first resolution in four years to expand the sanctions regime on North Korea.

"We believe that action taken by the Council should be prudent, measured, proportionate, and conducive to stability," Chinese Ambassador Li Baodong said after the vote.

China's agreement to join a resolution is a step away from the protection it usually gives to North Korea, its neighbor, which it supported in the Korean War in the early 1950s against U.S.-led U.N. troops.

China is seen as North Korea's closest ally, and its protection of North Korea meant that the Security Council previously denounced North Korea's launches with non-binding council statements, which are unenforceable.

In a defiant statement early Wednesday, North Korea's Foreign Ministry warned that it will strengthen its military and nuclear defenses in reaction to what it called evidence of "U.S. hostility" toward Pyongyang. It also warned that it would rebuff any attempt to engage Pyongyang in disarmament negotiations.

"There can be talks for peace and stability of the Korean Peninsula and the region in the future, but no talks for the denuclearization of the peninsula," the Foreign Ministry said in a memorandum carried by the state-run Korean Central News Agency.

North Korea ominously warned that it would take steps to "bolster the military capabilities for self-defense, including the nuclear deterrence."

North Korea sent a satellite into space on Dec. 12 aboard a long-range rocket, a launch that the U.S. and its allies have criticized as a test of banned ballistic missile technology. Pyongyang maintains the launch was a peaceful bid to send a satellite into space and North Korean leader Kim Jong Un cited its success in his New Year's Day speech.

In 2006 and 2009, Pyongyang conducted atomic tests after being slapped with Security Council condemnation and sanctions for similar launches of long-range rockets.

Security Council resolutions ban North Korea from any use of ballistic missile technology, even if characterized as a satellite launch or space launch vehicle.

The resolution imposes new sanctions under existing authorities on North Korean companies and government agencies, including North Korea's space agency and several individuals.

It also updates lists of nuclear and ballistic missile technology banned for transfer to and from North Korea and includes several new provisions targeting North Korea's smuggling of sensitive items that could contribute to the prohibited programs.

In its talks with China, the U.S. had to agree that the resolution would not bring in new forms of sanctions but would build on the existing Security Council sanction regimes.

""We hope that all relevant sides can, with a view to maintaining peace and stability, stay calm and restrained, and avoid all acts that will escalate tension, which is conducive to the interest of all sides," Chinese Foreign Ministry spokesman Qin Gang said in Beijing on Wednesday. He stressed the importance of moving ahead with the six-nation, aid-for-disarmament talks.

China's support for the new resolution comes at a time when the region braces for the possibility that North Korea may test a nuclear device as it did following previous rocket launches. Satellite photos taken at North Korea's nuclear test site in Punggye-ri last month indicated continued activity, even in winter, according to analysis by 38 North, a North Korea website affiliated with the Johns Hopkins School for Advanced International Studies.

North Korea vowed last week to strengthen its defenses amid concerns the country may conduct a nuclear test as a follow-up to last month's rocket launch.

Citing U.S. hostility, Pyongyang's Foreign Ministry said in a memorandum that North Korea will "continue to strengthen its deterrence against all forms of war."

The memorandum carried by state media did not say what action North Korea would take to defend itself. However, North Korea has claimed the right to build atomic weapons to protect itself from the United States, which stations more than 28,000 troops in South Korea.

Kindle Paperwhite-The World's Most Advanced E-Reader

Most Advanced E-Reader Display, 62% More Pixels, 25% More Contrast

Kindle Paperwhite's display is the most advanced e-reader display ever constructed. Featuring a 212 ppi display, Kindle Paperwhite has 62% more pixels than the previous generation Kindle, making text in books and periodicals crisp and clear at any size. Images are sharper, richer and show even more detail. Kindle Paperwhite's screen has 25% higher contrast than the previous generation Kindle- the blacks are blacker, and the whites are whiter.

Innovative Built-In Light

Backlit LCD displays direct light up through the display into the user's eyes. Kindle Paperwhite's patented front-lit display guides light underneath an anti-glare layer and down toward the display, away from the reader's eyes. This means a reader can read for hours with less eye fatigue and strain. The screen brightness is easily adjusted for reading in any light. The Paperwhite display provides an incredible experience in the dark and in direct sunlight.

Breakthrough Battery Life

Kindle Paperwhite's built-in front light is designed to be used at all times-both in daylight and in a dark room-for the clearest, crispest reading experience. In order to use the light at all times, Kindle Paperwhite requires exceptional power management to maintain the battery life that customers love about Kindle. Amazon's light guide technology precisely diffuses the light across the screen and only requires four LEDs to light the entire screen (unlike LCD screens which can use up to 50 LEDs). The light guide is so efficient that Kindle Paperwhite has a remarkable 8 weeks of battery life, even with the light on at all times.

Free 3G

Kindle's free 3G connection means customers never have to hunt for or pay for a Wi-Fi hotspot-they simply download and read books anytime, anywhere. Amazon pays for the 3G connection on Kindle Paperwhite Wi-Fi + 3G, so customers pay no monthly fees and sign no annual contracts.

Built-In Wi-Fi

Kindle Paperwhite comes with built-in Wi-Fi, letting readers discover new content at home or on the road anywhere you can access Wi-Fi.

New Touch Technology

Kindle Paperwhite's new capacitive touch technology is uniquely integrated into the Paperwhite display, allowing for a thinner form factor for Kindle Paperwhite and even better touch accuracy.

Slim and Sleek Design

At just over a third of an inch thin and weighing 213 grams, Kindle Paperwhite is thinner than a magazine and weighs less than a typical paperback. The bezel height between the side of the device and the display itself is 77% thinner.

Hand-Tuned Fonts

Every font on Kindle Paperwhite is hand-tuned for maximum readability. The Amazon typography team worked at the pixel level to ensure consistency of stroke thickness and shape profiles across all individual glyphs, aligning each size to the specific grid of the new Paperwhite display. This allows for unprecedented sharpness of fonts. Kindle Paperwhite's higher resolution display also allows for new elegant typeface options, such as Baskerville and Palatino, which use thin stems that would not render well on a lower resolution display.

"Buy Once, Read Everywhere"

With free reading apps, customers can read their Kindle books on a large number of devices and platforms, including any Kindle as well as on iPhone, iPad, Android devices, Mac, PC, or Windows Phone.

Whispersync

Amazon's Whispersync technology synchronizes a customer's last page read, bookmarks and annotations across all of their devices, so they can always pick up where they left off.

Time to Read

Time to Read is a new feature for Kindle Paperwhite that helps readers know the amount of time it will take them to finish a chapter or a book. This feature is smart-it personalizes the time for each customer based on their reading speed and is constantly updated as the reader's speed and habits change. With Time to Read, it's never been easier to decide when to start a new chapter or finish the chapter you're reading.

Kindle Direct Publishing

Independent authors and publishers can make their books available in the Canada Kindle Store using Kindle Direct Publishing (KDP) at http://kdp.amazon.ca. Canadian independent authors and publishers can utilize the English- or French-language KDP website to make their books available in Canada and more than 175 countries worldwide. They can also price their books and receive payments in Canadian dollars, earn up to 70% royalties on each book sold, all while retaining control of their content and copyrights.

Thousands of authors in Canada are already using KDP to make their books available in Kindle stores around the world, including Montreal resident Matthew Mather, the best-selling KDP author of the Complete Atopia Chronicles.

"My experience self-publishing with KDP has been nothing short of amazing," said Matthew Mather. "Within weeks of publishing, my book climbed to #1 on the science fiction best sellers list, and now I've sold tens of thousands of copies. I've just finished my second novel, "CyberStorm," and look forward to the idea of writing for a living, something I hadn't imagined possible just six months ago. The best part, though, has been the interaction with readers. I get emails from every corner of the world, contacting me to say how much they liked my work. This is an amazing feeling!"
