US says hacking undermines China's interests

BEIJING (AP) ? Hacking that originates inside China is undermining its relationship with the United States and harms Beijing's long-term interests, a U.S. diplomat said Tuesday, in the latest high-level public expression of concern over a problem that has prompted threats of commercial retaliation from Washington.

The U.S. believes cyber intrusions originating from China that result in the theft of sensitive information have reached very high levels, adding to existing problems with the lack of protection for intellectual property rights, said Robert Hormats, the U.S. undersecretary of state for economic growth.

He urged China to take firm action against hacking and said Chinese officials need to question whether such activity "serves China's real interests" as it seeks to upgrade its economy, the world's second largest.

"The long-term interest of the Chinese government is to investigate and halt these cyber intrusions wherever in this country they come from," Hormats said. "The U.S. government is taking an active role in addressing this issue and we continue to raise our concerns with senior Chinese officials."

Hormats' comments in an address to an Internet industry conference in Beijing follow a forensically detailed report by Internet security company Mandiant that accused a Chinese military unit of carrying out a yearslong hacking attack against U.S. companies.

China's government and military deny carrying out cyberattacks. A senior Chinese official attending the conference repeated Beijing's contention that Beijing was itself a victim of hacking.

"Our opposition to all forms of hacking is clear and consistent," said Qian Xiaoqian, a vice minister and deputy director of the State Internet Information Office.

"Lately people have been cooking up a theory of a Chinese Internet threat, which is just an extension of the old 'China threat' and just as groundless," Qian said.

Such statements seem to be doing little to allay concerns over a suspected official role in wholesale hacking linked to China. Foreign military and government organizations have been targeted by the attacks, as well as private companies, including those in sensitive industries such as energy and aerospace.

Craig Mundie, a senior adviser to the CEO of Microsoft, a sponsor of the conference, said that regardless of whether China-based hacking was the work of rogue actors, Beijing's efforts to stop it are clearly not effective.

"And given that China's policy position is that such activity is absolutely illegal, our two countries clearly need to work together to figure out how to enforce that policy more effectively, because right now the evidence suggests China's policy enforcement approaches are not working adequately," Mundie said.

Mandiant, a Virginia-based cybersecurity firm, released a torrent of details in February that tied a secret Chinese military unit in Shanghai to years of cyberattacks that compromised more than 140 companies. Mandiant linked the breaches to the People's Liberation Army's Unit 61398.

In response to the hacking reports, the Obama administration has been considering fines and other trade actions against China or any other country guilty of cyberespionage.

However, the administration is expected to proceed cautiously because of the issue's sensitivity, and Hormats and other conference attendees repeatedly called for communication and joint efforts against hacking rather than outright confrontation.

North Korea warns foreigners to leave South

SEOUL (Reuters) - North Korea warned foreigners in South Korea on Tuesday to quit the country because they were at risk in the event of conflict, the latest threat of war from Pyongyang. Soaring tensions on the peninsula have been fuelled by North Korean anger over the imposition of U.N. sanctions after its last nuclear arms test in February, creating one of the worst crises since the end of the Korean War in 1953.

"Iron Lady" Thatcher mourned, but critics speak out

LONDON (Reuters) - Britain and admirers worldwide are mourning Margaret Thatcher, who has died aged 87, as the "Iron Lady" who rolled back the state and faced down her enemies during 11 years as Britain's first woman prime minister. Her impact on the 1980s was such that opponents, including Labour's Tony Blair and Soviet leader Mikhail Gorbachev, led tributes to a legacy that radically transformed the British economy along free-market lines now widely taken for granted and includes her role in the peaceful end to the Cold War.

Japan's quake-crippled nuclear plant "losing faith" in leaking water pits

TOKYO (Reuters) - The company that runs a Japanese nuclear power plant destroyed by a tsunami two years ago said on Tuesday it was losing faith in temporary storage pits for radioactive water - but it doesn't have anywhere else to put it. Tokyo Electric Power Co (Tepco) said it had found a suspected new leak at one of the pits at the Fukushima Daiichi plant. If confirmed, that would mean three out of seven storage pits were now leaking, compounding clean-up difficulties after the world's worst nuclear crisis in 25 years.

Iran opens uranium mines, yellow cake plant

DUBAI (Reuters) - Iran said on Tuesday it had started production at two uranium mines and a yellow cake plant, declaring that Western opposition would not slow its nuclear program days after talks between Tehran and world powers failed to reach an accord. The country opened the Saghand 1 and 2 uranium mines in the central city of Yazd, which will extract uranium from a depth of 350 meters, and the Shahid Rezaeinejad yellow cake plant at Ardakan to mark Iran's National Nuclear Technology Day, state news agency IRNA said.

Suicide car bomber kills 15 in central Damascus

BEIRUT (Reuters) - A suicide car bomb killed at least 15 people and wounded 53 in the main business district of Damascus on Monday in what the Syrian prime minister said was a response to army gains against rebels around the capital. The bomb near a school in the Sabaa Bahrat district, which also houses the Central Bank and Finance Ministry, set cars ablaze and damaged buildings, state television footage showed.

Australia PM eyes trilateral naval exercises with China and U.S.

BEIJING (Reuters) - Australia is hoping to see trilateral naval exercises with China and the United States and is pursuing a new strategic partnership with Asia's biggest economy, Prime Minister Julia Gillard said on Tuesday. Gillard, speaking in Beijing at a trade forum, said Australia was seeking more cooperation with China in clean energy and emissions trading.

Defense Secretary Hagel to visit Israel this month: official

JERUSALEM (Reuters) - Defense Secretary Chuck Hagel will pay a first visit to Israel since taking office later this month to bolster the allies' cooperation in the Middle East, an Israeli official told Reuters on Tuesday. Hagel and his counterpart, Israeli Defence Minister Moshe Yaalon who is also newly appointed, discussed the visit by phone last month, the Israeli Defence Ministry said. The official said Hagel would visit between April 21-23.

Venezuela's Maduro vows to battle corruption

CARACAS (Reuters) - Acting President Nicolas Maduro vowed on Monday to stamp out corruption following days of accusations by his election rival Henrique Capriles that ruling party officials were plundering Venezuela's oil wealth. Corruption has been a perennial problem in the country and was a primary campaign issue for the late socialist leader Hugo Chavez when he was first elected in 1998. His death from cancer last month triggered the April 14 election.

U.N. warns of risk of Mali war spillover in Western Sahara

UNITED NATIONS (Reuters) - The conflict in Mali threatens to spill over into the disputed territory of Western Sahara and the Polisario Front independence movement has warned the United Nations of the possibility of "terrorist infiltrations," the U.N. chief said in a new report. Morocco took control of most of Western Sahara in 1975 when colonial power Spain withdrew, prompting a guerrilla war for independence that lasted until 1991 when the United Nations brokered a cease-fire and sent in a peacekeeping mission known as MINURSO.

Man kills 13 relatives and neighbours in Serb village

BELGRADE (Reuters) - A man in Serbia shot dead 13 people, mainly relatives and neighbors, in a village south of the capital Belgrade on Tuesday, police said. Twelve people died at the scene and one in hospital. The gunman shot himself and his wife but it was not clear what their condition was.

IDC: PC shipments in Q1 faced their steepest known drop to date

IDC PC shipments in Q1 faced their steepest drop known to date

If Windows 8 is the ticket to a bounce-back in PC sales, it's going to be a long, slow recovery. At least, as long as you ask IDC. It estimates that worldwide computer shipments in the first quarter of 2013 fell 13.9 percent to 76.3 million, which is the steepest quarterly drop the research firm has recorded since it started tracking PCs back in 1994. While the exact factors at work aren't clear, IDC blames it on a mix of customers spooked by Windows 8's unfamiliar interface, the continued rise of mobile devices, and the decline of the netbook. This isn't helped by the higher typical prices of touchscreen PCs, or by restructuring efforts at computing giants like Dell and HP.

Who's reigning in this apparently declining PC empire, then? Worldwide, it's a different picture than it was a few months ago: HP is back on top at 15.7 percent, followed by Lenovo, Dell, Acer and ASUS. The American climate is somewhat more familiar, with HP in front at 25.1 percent while being chased by Dell, Apple, Toshiba and Lenovo. With the exception of Lenovo, however, virtually all of the manufacturers involved saw at least some decline in their PC shipments. To IDC, that's a sign that vendors and Microsoft need to find an antidote to the crazes for smartphones and tablets -- and find it quickly.

Macy's Looking to Finish Off JC Penney in Court ... - Yahoo! Finance

After a court-ordered mediation period seems to have hit a brick wall, Macy's (M), Martha Stewart Living Omnimedia (MSO) and J.C. Penney (JCP) will be back in New York state court this week. As previously discussed on Breakout, the case is a love triangle of sorts. Macy's claims they have a five-year exclusive deal with Martha and that JCP's efforts to open MSO "stores within a store" clearly violate the terms of the contract.

The case is relatively small potatoes for Macy's, and CEO Terry Lundgren and his legal team have made noise about financial damages to Macy's. But given JCP's collapsing sales ? with or without Martha ? such claims seem designed more for legal positioning than financial peril. Brian Sozzi, CEO of Belus Capital Advisors, suggests JCP has a lot more riding on the outcome and traders know it.

"Since the trial began on February 20, JCP shares are down 25%, Macy's up 10%," Sozzi points out. "So what is Mr. Market saying? That Macy's is going to put the final knife, the final dagger, into the heart of J.C. Penney."

New York Supreme Court Justice Jeffrey Oing is clearly aware that a draconian ruling against JCP and MSO could be a death blow for either or both companies.

JCP CEO Ron Johnson didn't just sign off on the attempt to exploit a perceived loophole in Stewart's contract with Macy's, he also invested $38.5 million for a 16.6% stake of MSO. The deal placed a value of $3.50 a share for MSO, roughly 30% higher than where the stock is trading today.

Making matters even worse, Sozzi notes that JCP has Stewart goods sitting in inventory and literally floating on cargo ships waiting to be delivered to JCP stores. Without those goods JCP will be forced to continue its remodeling efforts with a giant hole in the store where the Martha Stewart "store" was supposed to be.

Sozzi says JCP has a real survival risk should they lose this case. If those Martha Stewart goods can't be sold, JCP's Home Department will be completely irrelevant and still under construction for months to come. A company with Penney's growing liquidity concerns can't afford to keep one-fifth of its stores boarded up through the holidays ? assuming they even make it that long.

Macy's wins regardless of the outcome simply by keeping JCP in court. A ruling in Macy's favor just might be the end of J.C. Penney entirely. "Macy's is going to have a grand holiday season," Sozzi concludes. "If they win this case, they still have Martha. They can run those commercials, and they can really put J.C. Penney down into the toilet."

It would seem that hell hath no fury like Terry Lundgren scorned.

Advancing secure communications: A better single-photon emitter for quantum cryptography

Apr. 9, 2013 ? In a development that could make the advanced form of secure communications known as quantum cryptography more practical, University of Michigan researchers have demonstrated a simpler, more efficient single-photon emitter that can be made using traditional semiconductor processing techniques.

Single-photon emitters release one particle of light, or photon, at a time, as opposed to devices like lasers that release a stream of them. Single-photon emitters are essential for quantum cryptography, which keeps secrets safe by taking advantage of the so-called observer effect: The very act of an eavesdropper listening in jumbles the message. This is because in the quantum realm, observing a system always changes it.

For quantum cryptography to work, it's necessary to encode the message -- which could be a bank password or a piece of military intelligence, for example -- just one photon at a time. That way, the sender and the recipient will know whether anyone has tampered with the message.

While the U-M researchers didn't make the first single-photon emitter, they say their new device improves upon the current technology and is much easier to make.

"This thing is very, very simple. It is all based on silicon," said Pallab Bhattacharya, the Charles M. Vest Distinguished University Professor of Electrical Engineering and Computer Science, and the James R. Mellor Professor of Engineering.

Bhattacharya, who leads this project, is a co-author of a paper on the work published in Nature Communications on April 9.

Bhattacharya's emitter is a single nanowire made of gallium nitride with a very small region of indium gallium nitride that behaves as a quantum dot. A quantum dot is a nanostructure that can generate a bit of information. In the binary code of conventional computers, a bit is a 0 or a 1. A quantum bit can be either or both at the same time.

The semiconducting materials the new emitter is made of are commonly used in LEDs and solar cells. The researchers grew the nanowires on a wafer of silicon. Because their technique is silicon-based, the infrastructure to manufacture the emitters on a larger scale already exists. Silicon is the basis of modern electronics.

"This is a big step in that it produces the pathway to realizing a practical electrically injected single-photon emitter," Bhattacharya said.

Key enablers of the new technology are size and compactness.

"By making the diameter of the nanowire very small and by altering the composition over a very small section of it, a quantum dot is realized," Bhattacharya said. "The quantum dot emits single-photons upon electrical excitation."

The U-M emitter is fueled by electricity, rather than light -- another aspect that makes it more practical. And each photon it emits possesses the same degree of linear polarization. Polarization refers to the orientation of the electric field of a beam of light. Most other single-photon emitters release light particles with a random polarization.

"So half might have one polarization and the other half might have the other," Bhattacharya said. "So in cryptic message, if you want to code them, you would only be able to use 50 percent of the photons. With our device, you could use almost all of them."

This device operates at cold temperatures, but the researchers are working on one that operates closer to room temperature.

The paper is titled "Electrically-driven polarized single-photon emission from an InGaN quantum dot in a GaN nanowire." The first author is Saniya Deshpande, a graduate student in electrical engineering and computer science. The work is supported by the National Science Foundation. The device was fabricated at the U-M Lurie Nanofabrication Facility.

Fasten seatbelts, air passengers. Climate change ahead.

Transatlantic flights will be bumpier by 2050 because of rising CO2 emissions, a new study finds. Turbulent episodes could double and the average strength of turbulence would also rise 10 to 40 percent. ?

By Nina Chestney,?Reuters / April 9, 2013

An aircraft flies over Frankfurt, Germany, in 2012. A new study suggests climate change could double the chances of airline passengers hitting significant turbulence over the Atlantic by 2050.

Turbulence on transatlantic flights will become more frequent and severe by 2050 as carbon dioxide emissions rise, leading to longer journey times and increased fuel consumption, British scientists said in a study on Monday.

Any air traveller has probably experienced turbulence. It can happen without warning and is caused by climate conditions such as atmospheric pressure, jet streams, cold and warm fronts or thunderstorms.

Light turbulence shakes the aircraft, but more severe episodes can injure passengers and cause structural damage to planes, costing around an estimated $150 million a year.

Turbulence will be stronger and occur more often if carbon dioxide emissions double by 2050 as the International Energy Agency forecasts, scientists at the universities of Reading and East Anglia said in the study published in the journal Nature Climate Change.

Carbon dioxide is one of the most potent greenhouse gases blamed for global warming. Increasing emissions raise the global average temperature, heating up the lower atmosphere.

However, warming also changes the atmosphere 10 km above ground level, making it more unstable for planes, Paul Williams at the University of Reading and co-author of the report, told Reuters.

FASTEN YOUR SEATBELTS

The scientists focused on the North Atlantic flight corridor - where 600 planes travel between Europe and North America each day - using computer simulations to examine the effects of climate change on conditions there.

They found that the chances of encountering significant turbulence by the middle of the century will increase by between 40 and 170 percent, with the most likely outcome being a doubling of airspace containing significant turbulence.

The average strength of turbulence would also increase by between 10 and 40 percent.

Bumpier air journeys would make flying more uncomfortable and raise the risks to passengers and crew.

Detours to avoid strong patches of turbulence would lengthen flight times, increasing fuel consumption, emissions and airport delays, which would ultimately drive up ticket prices, Williams said.

Air travel is one of the fastest-growing sources of carbon dioxide emissions, but the effects of climate change on turbulence have not been studied before.

"Aviation is partly responsible for changing the climate in the first place. It is ironic that the climate looks set to exact its revenge by creating a more turbulent atmosphere for flying," Williams said.

The International Air Transport Association said the issue of climate sensitivity still held many uncertainties and the study would not change airline procedures.

The aviation sector is aiming to halve its net CO2 emissions by 2050 from 2005 levels through new technology, alternative fuels and increased efficiency.

There have also been attempts to tax the sector amid slow progress towards a global deal on curbing aviation emissions.

The European Union tried to force all airlines landing or taking off from EU airports to pay for their emissions last year through its carbon trading scheme. But opposition was so fierce it almost led to a trade war, so the law was frozen for a year for inter-continental flights.
