BEIJING, Jan. 24 (Xinhua) -- China's meteorological authority said Tuesday that the country's northern regions will continue to have sunny weather for the coming 24 hours, while the south will see subdued rain and snow.Temperatures in most parts of the country are expected to rebound slightly, the National Meteorological Center said in a statement on its website.But the lowest temperatures in the areas south of the Yangtze River will remain around zero degree Celsius, the center said.Meanwhile, rain and snow will subdue in most parts of the southern regions over the next three days, although freezing rain is forecast to hit Guizhou and Hunan provinces, according to the statement.

WASHINGTON, Oct. 9 (Xinhua) -- U.S. researchers have found a way to block, in an animal model, the damaging inflammation that contributes to many disease conditions. In their report receiving early online publication Sunday in Nature Biotechnology, researchers describe using small interfering RNA technology to silence the biochemical signals that attract a particular group of inflammatory cells to areas of tissue damage."The white blood cells known as monocytes play a critical role in the early stages of the immune response," says Matthias Nahrendorf, of the Massachusetts General Hospital (MGH) Center for Systems Biology, the paper's senior author. "We now know there are two subsets of monocytes -- an inflammatory subset that defends against pathogens and a reparative subset that supports healing. But if the inflammatory response is excessive, it can block the healing process and exacerbate conditions such as heart disease and cancer."Cells damaged by injury or disease release a cocktail of chemicals called cytokines that attract immune cells to the site of the damage. Inflammatory monocytes are guided to sites of tissue injury by a receptor protein called CCR2, and the MGH-led team devised a strategy targeting that molecule to block the inflammatory process but not the action of the reparative monocytes.Small interfering RNA (siRNA) technology prevents production of specific proteins by binding to associated messenger RNA molecules and preventing their translation. However, the technique requires extreme precision in developing the right siRNA molecule and delivering it to the correct cellular location.To make sure that their siRNA preparation targeted the right monocytes, researchers first confirmed that its use reduced levels of CCR2 in monocytes and increased levels of the fragments produced when siRNA binds to its target. They then showed that monocytes from mice treated with the siRNA preparation were unable to migrate towards CCR2's usual molecular target. Experiments in animal models of several important diseases showed that the siRNA preparation reduced the amount of cardiac muscle damaged by a heart attack, reduced the size and the number of inflammatory cells in atherosclerotic plaques and in lymphomas, and improved the survival of transplanted pancreatic islets."These inflammatory monocytes are involved in almost every major disease," Nahrendorf explains. "Anti-inflammatory drugs currently on the market hit every inflammatory cell in the body, which can produce unwanted side effects. This new siRNA treatment doesn't affect inflammatory cells that don't rely on the CCR2 receptor. That makes a big difference."

BEIJING, Dec. 20 (Xinhua) -- A senior Chinese official called for a higher level of requirements for promoting cultural and ethical progress at a national conference Tuesday.Li Changchun, a member of the Standing Committee of the Political Bureau of the Communist Party of China (CPC) Central Committee urged for efforts to "provide firm ideological assurance, powerful spiritual drive, effective media support and sound cultural conditions for achieving the great goal of building an overall prosperous society."Li, also director of the Central Spiritual Civilization Development Steering Commission, made the remark while addressing the National Award-issuing Conference on the Work of Cultural and Ethical Progress.Li Changchun (1st L), a Standing Committee member of the Political Bureau of the Communist Party of China (CPC) Central Committee and director of the Central Spiritual Civilization Development Steering Commission, presents the awards to the advanced collectives and individuals during the National Award-issuing Conference on the Work of Cultural and Ethical Progress held in Beijing, capital of China, Dec. 20, 2011. Li attended the conference on Tuesday and gave a speech.In his speech, Li extended his gratefulness to everyone engaged in cultural and ethical work at all levels, as well as to people from all walks of life for their active participation in, and support of, the work.Currently, publicizing the Party's new plenary session should be the primary task in cultural and ethical work, Li said."Cultural and ethical progress is a major component of the socialist cause with China's own characteristics," he said, emphasizing that substantial efforts must be made to strengthen Party leadership on the work.The meeting was presided over by Liu Yunshan, a member of the Political Bureau of the CPC Central Committee and deputy-director of the Central Spiritual Civilization Development Steering Commission.In an address at the gathering, he called for greater efforts in publicizing the models of cultural and ethical progress, so as to "enhance the level of civilization of the society as a whole."A total of 27 cities and municipal districts, 899 villages and small towns, and 1,794 institutions and enterprises were awarded for their marked achievements in cultural and ethical progress, and 23 cities and municipal districts that had been previously awarded were allowed to keep their honorary titles.

SAN FRANCISCO, Dec. 9 (Xinhua) -- Hewlett-Packard (HP) on Friday announced that it is keeping the webOS software alive by contributing it to the open source community.The company said it will make the underlying code of webOS available under an open source license and will engage the open source community to help define the charter of the open source project."WebOS is the only platform designed from the ground up to be mobile, cloud-connected and scalable," Meg Whitman, HP's chief executive officer, said in a statement."By contributing this innovation, HP unleashes the creativity of the open source community to advance a new generation of applications and devices," she added.HP said it will remain active in the development and support of webOS, while the source code will be available for use and improvement by anyone choosing to download it, which means other hardware manufacturers can also use the software.With the help of the open source community, HP can save development and other costs and the new announcement is expected to result in more layoffs from its webOS team, some analysts noted.The webOS is a mobile operating system initially developed by Palm which was acquired by HP last April for 1.2 billion U.S. dollars.In February this year, HP released TouchPad, its first tablet computer which runs the webOS operating system. The device didn't sell well, and HP in August decided to completely shut down webOS hardware business, including TouchPad and webOS phones.HP then said that it will continue to explore options to optimize the value of webOS software going forward.By keeping the software open source, users of webOS devices will continue to receive software improvements and updates in the future, HP noted."As webOS gains traction as an open source alternative in the marketplace, you could see webOS on several different types of devices by any number of vendors. We will explore the viability of putting webOS on devices, just as we do for other leading operating systems," the company said in a corporate blog post.

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.
