KentuckyFC writes "The early symptoms of many diseases show up first in the smallest blood vessels, but imaging the fine structure of these vessels is a tricky problem for medics. The most common way is to inject them with a contrast agent and use x-ray tomography to create a 3D image of their structure. This shows problems in the large vessels but not smaller ones. The problem is the lack of contrast. Conventional contrast agents are based on iodine, which has a high electron density and so better absorbs x-rays than other atoms. But a better solution would be to use a higher density fluid, such as a liquid metal. The obvious fears associated with toxicity and so forth mean this has never been tried. Until now. A team of Chinese biomedical engineers have created the world's first images of a pig's heart injected with gallium. This has a melting point of 29 degrees C, so it's a liquid at body temperature. And the results show the detailed structure of the tiniest blood vessels, revealing capillaries just 0.07 mm in diameter. That's significantly more detailed than is possible with iodine-based contrast agents. An important question is whether this technique will ever be possible in humans. The Chinese team seems optimistic. They say gallium is chemically inert, non-toxic to humans and can be injected and sucked out without leaving a residue. 'It suggests the possibility for localized in vivo vascular-enhanced radiological imaging in the near future.'"

Nerval's Lobster writes "Bank of America has issued a research report suggesting that the crypto-currency Bitcoin could become 'a major means of payment for e-commerce' on its way to emerging as 'a serious competitor to traditional money transfer providers.' The bank attaches a 'maximum market capitalization' of Bitcoin at roughly $1,300, based on its position as a 'major player in both e-commerce and money transfer' as well as 'a significant store of value with a reputation close to silver.' Bitcoin has come close to exceeding that theoretical ceiling in recent weeks, although its valuation dove today after the People's Bank of China decided to declare it a volatile 'currency' without real legal status; that financial institution is also concerned about its use in money laundering and black markets. Bank of America sees Bitcoins' advantages as low transaction costs, its finite supply (which will protect its value), and its increasing attractiveness as an alternative to 'traditional' cash. As with the People's Bank of China, however, the bank sees the currency's extreme volatility and lack of legal backing as a bad thing, and frowns at the possibility that regulators could step in and increase transaction costs. 'A 50 minute wait before payment receipt confirmation is received will prohibit wider use,' the report adds. 'This is less of an issue for two parties that know each other because they trust the other will not double spend, but when dealing with an anonymous counterparty this creates a high level of unhedgeable risk.' Without a 'central counterparty' to verify transactions and thus mitigate that risk, Bitcoin could fail to break into wider use."
alphadogg writes "There are currently several million smartphones certified to run on a 'HotSpot 2.0' Wi-Fi network, which promises automatic Wi-Fi authentication and connection, and seamless roaming between different Wi-Fi hotspot brands, and eventually between Wi-Fi and cellular connections. In November, about 400 smartphone users finally got a chance to do so — in Beijing, China. The next big public demonstration of what's confusingly referred to as both Hotspot 2.0 and Next Generation Hotspot will be in February: an estimated 75,000 attendees at the next Mobile World Congress in Barcelona will be able to take part."
quantr writes with this excerpt from Bloomberg: "China's central bank barred financial institutions from handling Bitcoin transactions, moving to regulate the virtual currency after an 89-fold jump in its value sparked a surge of investor interest in the country. Bitcoin plunged more than 20 percent to below $1,000 on the BitStamp Internet exchange after the People's Bank of China said it isn't a currency with 'real meaning' and doesn't have the same legal status. The public is free to participate in Internet transactions provided they take on the risk themselves, it said. The ban reflects concern about the risk the digital currency may pose to China's capital controls and financial stability after a surge in trading this year made the country the world's biggest trader of Bitcoin, according to exchange operator BTC China. Bitcoin's price jumped more than ninefold in the past two months alone, prompting former Federal Reserve Chairman Alan Greenspan to call it a 'bubble.' 'The concern is that it interferes with normal monetary policy operation,' said Hao Hong, head of China research at Bocom International Holdings Co. in Hong Kong. 'It represents an unofficial leakage to the current monetary system and trades globally. It is difficult to regulate and could be used for money laundering.'"
tdog17 writes "China says it wants Microsoft to extend support for Windows XP because that will help in its fight to stop proliferation of pirated Microsoft software. A state copyright official says the release of Windows 8 means a substantial increase in the selling price of a Windows operating system, especially in light of the upcoming end-of-life of Windows XP, which is still used by a large percentage of Chinese. That could drive users to buy pirated copies of a new operating system because they are cheaper, he says."
CowboyRobot writes "In November, Denmark-based Bitcoin Internet Payment System suffered a DDoS attack. Unfortunately for users of the company's free online wallets for storing bitcoins, the DDoS attack was merely a smokescreen for a digital heist that quickly drained numerous wallets, netting the attackers a reported 1,295 bitcoins — worth nearly $1 million — and leaving wallet users with little chance that they'd ever see their money again. Given the potential spoils from a successful online heist, related attacks are becoming more common. But not all bitcoin heists have been executed via hack attacks or malware. For example, a China-based bitcoin exchange called GBL launched in May. Almost 1,000 people used the service to deposit bitcoins worth about $4.1 million. But the exchange was revealed to be an elaborate scam after whoever launched the site shut it down on October 26 and absconded with the funds. The warnings are all the same: 'Don't trust any online wallet', 'Find alternative storage solutions as soon as possible', and 'You don't have to keep your Bitcoins online with someone else. You can store your Bitcoins yourself, encrypted and offline.'"

An anonymous reader writes "Until now, it was particularly difficult to obtain reliable figures on the results of the Android operating system in China. Indeed, there is no 'centralized app store' and most smartphones sold in the country do not use Google services, including activation. In fact, it is very difficult to know the actual results. The search engine Baidu has corrected this by publishing a report on trends in the mobile internet for the 3rd quarter 2013. It appears that there would be now 270 million active users of the Google platform in the country (more than 20% of the total population). Growth would, however, decrease with a small 13% against 55% for the same period last year but up 10% compared to Q2 2013."
jones_supa writes "Talouselämä Magazine met Jolla CEO Tomi Pienimäki and asked a puzzling question. If Jolla truly is compatible with Android devices, is Jolla going to let individual users to install the Sailfish operating system on the Android devices that they already have? Pienimäki answers: 'That is the plan. We are on device business and OS business. It is fairly easy to install the OS on Android devices'. He says that especially in China, changing firmwares is a mainstream thing. About half of the smartphone buyers are upgrading their older or cheaper devices with a better version of Android. Therefore, Jolla's plan is to get some Sailfish installations sneaked in, too."
c0lo writes "A Chinese Long March rocket is scheduled to blast off to the Moon on Sunday evening at about 6pm UTC carrying a small robotic rover that will touch down on to the lunar surface in about two weeks' time – the first soft landing on the Earth's only natural satellite since 1976. China has been methodically and patiently building up the key elements needed for an advanced space programme — from launchers to manned missions in Earth orbit to unmanned planetary craft — and it is investing heavily. After only 10 years since it independently sent its first astronaut into space, China is forging ahead with a bold three-step programme beginning with the robotic exploration of possible landing sites for the first Chinese astronauts to set foot on lunar soil between 2025 and 2030. Prof Ouyang Ziyuan of the department of lunar and deep space exploration and an adviser to the mission commented to the BBC on the scale of Chinese thinking about the Moon. He said the forthcoming venture would land in an ancient crater 400km wide called Sinus Iridum, thought to be relatively flat and clear of rocks, and explore its geology. China.org.cn promised live coverage of the event."
cold fjord writes "France24 reports, "Beijing on Saturday announced it was setting up an 'air defence identification zone' over an area that includes islands controlled by Japan but claimed by China, in a move that could inflame the bitter territorial row. Along with the creation of the zone in the East China Sea, the defence ministry released a set of aircraft identification rules that must be followed by all planes entering the area, under penalty of intervention by the military. Aircraft are expected to provide their flight plan, clearly mark their nationality, and maintain two-way radio communication allowing them to 'respond in a timely and accurate manner to the identification inquiries' from Chinese authorities. The outline of the new zone ... covers a wide area of the East China Sea between South Korea and Taiwan that includes the Tokyo-controlled islands known as the Senkakus to Japan and Diaoyous to China. "China's armed forces will adopt defensive emergency measures to respond to aircraft that do not cooperate in the identification or refuse to follow the instructions," according to the ministry. ' The Politico adds, "Secretary of Defense Chuck Hagel said Saturday the United States is 'deeply concerned'" over the move. Spiegel Online has background on the conflict with Japan and on related regional issues. This announcement follows the recent publication in Chinese state media of maps showing nuclear strike plans against the U.S."
dcblogs writes "In the global race to build the next generation of supercomputers — exascale — there is no guarantee the U.S. will finish first. But the stakes are high for the U.S. tech industry. Today, U.S. firms — Hewlett-Packard, IBM and Intel, in particular — dominate the global high performance computing (HPC) market. On the Top 500 list, the worldwide ranking of the most powerful supercomputers, HP now has 39% of the systems, IBM, 33%, and Cray, nearly 10%. That lopsided U.S. market share does not sit well with other countries, which are busy building their own chips, interconnects, and their own high-tech industries in the push for exascale. Europe and China are deep into effort to build exascale machines, and now so is Japan. Kimihiko Hirao, director of the RIKEN Advanced Institute for Computational Science of Japan, said Japan is prepping a system for 2020. Asked whether he sees the push to exascale as a race between nations, Hirao said yes. Will Japan try to win that race? 'I hope so,' he said. 'We are rather confident,' said Hirao, arguing that Japan has the technology and the people to achieve the goal. Jack Dongarra, a professor of computer science at the University of Tennessee and one of the academic leaders of the Top 500 supercomputing list, said Japan is serious and on target to deliver a system by 2020."
Lasrick writes "Hugh Gusterson examines the crossroads at which the U.S. finds itself on the use of drones, and the long-term consequences of choices made now, by looking at the history of choices the U.S. made in the 1940s regarding nuclear weapons. Thoughtful read. Quoting: 'Having seen what drones are capable of, political leaders can choose to place clear limits, domestically and internationally, on how they can be used. Or, telling the American people that drones will make them safer or that "you can’t stop technology," they can allow free rein to those military inventors, national security bureaucrats and industry entrepreneurs eager to develop drone technology as aggressively as possible. Such people are impatient to press ahead with new unmanned aerial vehicles, including smart drones and mini-drones, to sell both to the US military for use overseas and to law-enforcement bodies within the United States. If drone development continues unchecked, what can we expect? First, as with nuclear weapons, proliferation. At the moment the United States, Britain, and Israel are the only countries to have used weaponized drones. But many countries, including Russia and China, have been watching carefully as Washington has experimented with counterinsurgency by drone, and are considering how they might use this relatively cheap technology for their own purposes. If they decide to use their own drones outside the boundaries of international law against people they brand “terrorists,” the United States will hardly be in a position to condemn them or counsel restraint.'"
jfruh writes "The new Chinese leadership released a document outlining its vision for the country Friday, and most of the attention was paid to reforms, like plans to loosen state control of the economy and end the one-child policy. But when it comes to the Internet, the Chinese Communist government is doubling down on its restrictive policies. The document notes that social networking and instant messaging tools can rapidly disseminate information and mobilize society; the government doesn't think those are good things, and plans to bolster its regulatory systems and increase the scope of their legal authority."
Velcroman1 writes "The tomb of brutal Mongolian emperor Genghis Khan — the one who created the world's most powerful empire by raiding and invading across Eurasia, not Kirk's nemesis — is a lost treasure archaeologists have sought for years. And one man thinks he knows where it is. Last fall Alan Nichols, the president of The Explorers Club, mapped out possible locations for the tomb of Khan (also known as Chinnggis Qa'an). His hypothesis: Khan's tomb is located in the Liupan Mountains in Northern China, where the emperor who was born in 1162 and is said to have perished from an arrow wound in August 1227. Next fall, Nichols plans the next phase of his research: pinpointing Khan's exact resting place. 'Ghengis Khan's tomb is my obsession,' Nichols, a noted authority on the emperor, said recently. 'I couldn't stop thinking about it. But I'm not happy just reading about it, or knowing about it. I need to have my feet on it.'"
miller60 writes "How do you cool a high-density server installation inside a high rise in Hong Kong? You dunk the servers, immersing them in fluid to create an extremely efficient HPC environment in a hot, humid location. Hong Kong's Allied Control developed its immersion cooling solution using a technique called open bath immersion (OBI), which uses 3M's Novec fluid. OBI is an example of passive two-phase cooling, which uses a boiling liquid to remove heat from a surface and then condenses the liquid for reuse, all without a pump. It's a slightly different approach to immersion cooling than the Green Revolution technique being tested by Intel and deployed at scale by energy companies. Other players in immersion cooling include Iceotope and Hardcore (now LiquidCool)."
KentuckyFC writes "Back in 2002, Severe Acute Respiratory Syndrome or SARS killed about 10 per cent of the 8,000 people it infected in southern China and Hong Kong. The severity of the disease and its high death rate triggered panic in many countries where health agencies worked feverishly to prevent its further spread, largely successfully. Then in September 2012, a virologist working in Saudi Arabia noticed a similar virus in a patient suffering from acute pneumonia and renal failure. Since then, so-called Middle East Respiratory Syndrome or MERS has also begun to spread. The World Health Organization says it knows of 63 deaths from only 149 cases, a death rate that seems to dwarf that of SARS. So how worried should we be? Now epidemiologists who have modeled how the disease spreads have some reassuring news. They say MERS is unlikely to cause a global pandemic. But with Saudi Arabia expecting the imminent arrival of millions of pilgrims for the 2013 Hajj, there are still good reasons to be concerned."

Hugh Pickens DOT Com writes "As we come up on Veteran's Day, Barrie Barber reports for the Dayton Daily News that the last Doolittle Raiders symbolically said goodbye to a decades-old tradition and to a history that changed the course of the Pacific war in World War II. Gathering from across the country together one last time, three surviving Raiders sipped from silver goblets engraved with their names and filled with 1896 Hennessy cognac in a once-private ceremony webcast to the world at the National Museum of the U.S. Air Force. Robert E. Cole, 98, led the final toast to the 80 members of 'the Greatest Generation' who took off in 16 B-25 Mitchell bombers April 18, 1942, from the deck of the USS Hornet to bomb Japan four months after a Japanese surprise naval and air attack on Pearl Harbor. 'Gentleman, I propose a toast,' said Cole, as about 700 spectators watched one final time, 'to those we lost on the mission and those that passed away since. Thank you very much and may they rest in peace.' Acting Secretary of the Air Force Eric Fanning said the raid showed the courage and innovation of the World War II airmen flying from a carrier in a bomber that had never seen combat to attack a heavily defended nation and to attempt to land at unseen airfields in China in a country occupied by Japanese troops. More than 70 years after the attack, Edward J. Saylor, 93, remembered ditching at sea once he and his crew dropped their bombs and several close calls with being discovered by the Japanese Army while making his way through China. 'This may be the last time I see them together,' said the 92-year-old raider who has attended Raider reunions since 1962. 'It's a little sad for me because I've known them so long and know the story of what they did in 1942.'"
