WASHINGTON, Jan. 16 (Xinhua) -- A new study examining weather patterns around the worldwide pandemics of influenza, which caused widespread death and illness in 1918, 1957, 1968 and 2009, finds that each of them was preceded by La Nina conditions in the equatorial Pacific. The study findings are published online Monday in the Proceedings of the National Academy of Science.The study's authors -- Jeffrey Shaman of Columbia University's Mailman School of Public Health and Marc Lipsitch of the Harvard School of Public Health -- note that the La Nina pattern is known to alter the migratory patterns of birds, which are thought to be a primary reservoir of human influenza. The scientists theorize that altered migration patterns promote the development of dangerous new strains of influenza.To examine the relationship between weather patterns and influenza pandemics, the researchers studied records of ocean temperatures in the equatorial Pacific in the fall and winter before the four most recent flu pandemics emerged. They found that all four pandemics were preceded by below-normal sea surface temperatures -- consistent with the La Nina phase of the El Nino- Southern Oscillation.The authors cite other research showing that the La Nina pattern alters the migration, stopover time, fitness and interspecies mixing of migratory birds. These conditions could favor the kind of gene swapping or genetic reassortment that creates novel and therefore potentially more variations of the influenza virus."We know that pandemics arise from dramatic changes in the influenza genome. Our hypothesis is that La Nina sets the stage for these changes by reshuffling the mixing patterns of migratory birds, which are a major reservoir for influenza," says Shaman.Changes in migration not only alter the pattern of contact among bird species, they could also change the ways that birds come into contact with domestic animals like pigs. Gene-swapping between avian and pig influenza viruses was a factor in the 2009 swine flu pandemic.

LOS ANGELES, Dec. 21 (Xinhua) -- The late Apple co-founder Steve Jobs will be honored posthumously with a Grammy award for his contributions to music technology, The Recording Academy announced on Wednesday.Jobs, who passed away Oct. 5 of pancreatic cancer, will receive a Trustees Award for helping create products "that transformed the way we consume music, TV, movies and books," the academy said in a prepared statement.The Apple Computer Inc. first received a Technical Grammy Award in 2002, for contributions of outstanding technical significance to the recording field, the academy said.Along with Jobs, bandleader and composer Dave Bartholomew, recording engineer Rudy Van Gelder will also receive the award.The academy also picked the Allman Brothers, Glen Campbell, Diana Ross and Brazilian pianist/singer/guitarist Antonio Carlos Jobim as recipients of Lifetime Achievement Awards. Jobim was known for composing "The Girl from Ipanema," a worldwide hit in the mid-1960s which won a Grammy for Record of the Year in 1965.Other artists, including trumpeter Wayne Jackson, saxophonist Andrew Love of the Memphis Horns,country legend George Jones,and the late Gil Scott-Heron were also named as recipients.German sound-technology firm Celemony and the late audio engineer Roger Nichols, who worked with artists including Ross, Placido Domingo, James Taylor and Stevie Wonder, were recognized with Grammy Technical Awards."This year's honorees offer a variety of brilliance, contributions and lasting impressions on our culture," said President/CEO of The Recording Academy Neil Portnow. "It is an honor to recognize such a diverse group of individuals whose talents and achievements have had an indelible impact on our industry."The honorees will be formally acknowledged during the 54th Annual Grammy Awards telecast at Staples Center in downtown Los Angeles on Feb. 12, 2012.

BEIJING, Nov. 1 (Xinhua) -- Commander-in-chief of China's manned space program Chang Wanquan announced early Tuesday that the launch of Shenzhou-8 unmanned spacecraft is successful.The spacecraft was successfully sent into the designated orbit after the blastoff at 5:58 a.m. at the Jiuquan Satellite Launch Center in northwestern desert area, carried by an upgraded Long March-2F rocket.It is heading to rendezvous with the Tiangong-1, or "Heavenly Palace-1" that was put into space on Sept. 29 for the country's first space docking.The docking, if successful, will pave the way for China to operate a permanent space station around 2020, and make the nation the world's third to do so.The launch was attended by Chinese Vice Premier Zhang Dejiang. It was also observed by senior experts from the European Space Agency and the German Aerospace Center at the launch site.The docking will happen within two days after the launch of the Shenzhou-8 at a height of 343 km above Earth's surface. The spacecraft will return to Earth after two docking operations.

LAS VEGAS, the United States, Jan. 12 (Xinhua) -- One of the most revolutionary changes for consumers that may come out of this year's International Consumer Electronics Show (CES) will not be the electronic devices themselves, but the way they are charged.Instead of using traditional cords to power mobile phones, kitchen appliances, and even vehicles, exhibits showcasing wireless power technologies offer a glimpse into the future of how individuals can charge their devices without a plug or cord.Fulton Innovation, who develops and licenses its eCoupled intelligent wireless technology, demonstrated how the technology could be applied across a variety of usage cases at home and at work.At CES, the company announced that it is releasing its next generation wireless power solutions that incorporate near-field resonant magnetic induction, allowing devices to charge without actually touching a charging surface.Additionally, it will allow power to transfer through metal surfaces, a property which had previously been unsafe to use as a surface conductor for power.While the products with integrated eCoupled capabilities currently in the marketplace focus predominantly on smartphone charging surfaces, in part due to the low-power demands of these devices, the company said there will be more applications using this technology expected to come to market in the near future.A large part of the added production scale on the consumer level is due to the standardization of the industry.In 2010, the Wireless Power Consortium (WPC) announced the finalization of the "Qi" standard, enabling interoperability for wireless charging between a power-providing device and electronics receiving power.Currently, the Qi standard is only applicable for the wireless transmission of power up to five watts, and the WPC is undertaking steps to expand this standard to deliver up to 120 watts of power.This standardization enables technology designers like Fulton Innovations to create underlying IP designs and technologies that work across a number of OEMs.The WPC currently has over 100 member companies, including Fulton Innovation, Nokia, Samsung, Haier, and Huawei Technologies.Fulton Innovation also expects to add its eCoupled technology to cars, giving automobile manufacturers the ability to install integrated charging platforms for mobile devices without additional wires or cords.Chinese auto makers Geely, Chery, Chang'an, and Dongfeng were the first to showcase cars at a major auto show featuring Qi standard charging stations during the April 2011 Shanghai Auto Show.The WPC estimates that there will be approximately five auto manufacturers who will release cars with Qi-enabled charging capabilities either late this year or early next year.

SEOUL, Nov. 8 (Xinhua) -- Samsung Electronics, the world's largest flat screen TV vendor, said Tuesday that it has suspended its plan to develop active shutter three-dimensional (3D) TVs with RealD, the U.S.-based 3D technology supplier."Samsung has decided to focus on our own initiatives of 3D technology, and continues to research and develop next-generation 3D display technologies, including a glasses-free 3D solution for the home," the tech firm said in an e-mailed statement.The active shutter 3D technology drew public attention after Samsung reached a deal with RealD earlier this year to jointly develop such technology, aiming to unveil 3D TVs based on the technology early next year.The active shutter is a next generation 3D technology that incorporates merits from both shutter-glass (SG) technology, which Samsung adopted, and film patterned retarder (FPR) technology, which LG introduced in December last year.The SG technology has been touted as better picture quality and deeper 3D images, but the eyewear is heavier because it requires batteries and chips to work. The active shutter 3D technology moved its function of 3D image creation from eyewear to flat panel, making the eyewear lighter.Despite the upgraded technology and its convenience, Samsung decided to focus on its existing SG technology as the global TV market is grappling with weak demand. The penetration rate, which gauges the ratio of 3D sets against the total flat screen TVs, was expected to rise to 9.9 percent by year-end from the 3 percent a year earlier, according to Woori Investment & Securities, a local securities firm.
