WELLINGTON, Oct. 17 (Xinhua) -- Parents wanting to help their children avoid asthma and other allergies are being told to give their toys a frosty reception by sticking them in the freezer.Medical scientists in New Zealand and Taiwan have discovered that freezing children's soft toys can kill almost all house dust mites (HDMs), the microscopic bugs associated with a range of allergies, including asthma.Other effective remedies for killing HDMs, commonly found in children's soft toys, were tumble drying and washing with eucalyptus oil and detergent, the scientists from New Zealand's University of Otago and Taiwan's Changhua Christian Hospital found.HDMs were strongly associated with the development of asthma in children, and the severity of asthma was in proportion to the number of house dust mites a child was exposed to when sleeping with soft toys, said a statement from the university Monday."Children frequently sleep with their favorite toys close to their airways and this may be important for HDM-sensitized asthmatic children," said University of Otago Associate Professor Rob Siebers.The scientists tested the three different cleaning methods on 36 toys divided into three groups of 12.Freezing toys for at least 16 hours at minus 15 degrees centigrade resulted in a 95-percent reduction of HDMs, as did soaking in an emulsion of eucalyptus oil and liquid detergent for one hour before rinsing and drying.Hot tumble drying for one hour reduced mites by 89 percent, the study found."Washing and soaking with eucalyptus oil and detergent is very effective in not only reducing live mites, but also reducing house dust mite allergens, compared to freezing and tumble drying," said Siebers.Ten of the 12 toys cleaned this way showed no live mites at all.Siebers said all three methods were more effective than just washing toys, because water needed to be above 55 degrees centigrade to kill HDMs, but this usually damaged the toys."My advice for parents is to either tumble dry for one hour, or freeze the soft toy overnight, and then wash it in a cold wash to remove any allergens."Siebers said the thickness of the material used in making the toys could alter the effectiveness of the three methods.The scientists would conduct further research to determine how quickly HDMs recolonized soft toys and how often toys should be treated.The study has been published in the European journal, Paediatric Allergy and Immunology.

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.

SAN FRANCISCO, Dec. 9 (Xinhua) -- Apple on Friday suffered a major setback in its global patent war, as a German court ruled over its copyright infringement battle in favor of Motorola Mobility.The German court ruled that Apple's iPhone and iPad infringe a Motorola patent and issued an injunction banning the import of iPhones and 3G-capable iPads into Germany.The dispute, one of Apple's several patent lawsuits around the world, is over a Motorola patent essential to GPRS. Motorola has been negotiating with Apple over licensing terms and conditions since 2007, and it will continue its efforts to resolve its global patent dispute as soon as practicable, said Motorola Mobility in a statement on Friday."We're going to appeal the court's ruling right away. Holiday shoppers in Germany should have no problem finding the iPad or iPhone they want," an Apple spokesman told tech news site AllThingsD.Apple is not too concerned about losing out in the Christmas shopping season as it has plenty of iPhones and iPads in Germany already, AllThingsD cited unidentified sources as saying.The ruling is against Apple's European sales company and only impacts its products sold in Germany. The German court also ruled that Motorola is entitled to a damages award.Apple can appeal the ruling to a higher court and request a stay of the injunction, according to a blog post of Florian Mueller, a U.S. patent expert who has been closely following patent lawsuits in the mobile industry.Mueller said should Apple make the appeal but the court declines the stay, Motorola must post a 100 million euro (around 134 million U.S. dollars) bond before the court will enforce the injunction.In August, Apple also filed a suit in Germany over the design of Motorola's tablet Xoom, which runs Google's Android system. But Apple did not make it clear whether it will seek to block the sales of Xoom in Europe.Also on Friday, Samsung won an appeal from the Australian High Court overturning a previous Apple victory that effectively banned Samsung from selling its Galaxy Tab in Australia.Based on claims of infringing Apple's patents, the Cupertino, California-based tech giant has been seeking court order to block Samsung's Galaxy line of mobile devices around the world.A German court issued an injunction in August, blocking Samsung from selling its Galaxy Tab 10.1 tablets across all European Union members, except for the Netherlands.On Thursday, Apple said it will appeal a San Jose, California judge's refusal to ban sales of Samsung 4G smartphones and Galaxy Tab 10.1 tablets in the United States.

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.

WASHINGTON, Nov. 14 (Xinhua) -- Vitamin D levels are significantly lower in patients with recurrent inflammatory spinal cord disease, according to a study published online Monday in Archives of Neurology.Vitamin D is a steroid vitamin that promotes the intestinal absorption and metabolism of calcium and phosphorus. In recent years, low levels of vitamin D have been linked to a variety of autoimmune conditions, including multiple sclerosis (MS). However, the importance of vitamin D in monophasic or recurrent non-MS spinal cord diseases including transverse myelitis and neuromyelitis optica is unknown, according to background information in the article.Transverse myelitis (TM) is a disease of the spinal cord in which there is involvement of the myelin sheath that protects nerve fibers; symptoms include back pain and weakness in the legs. Neuromyelitis optica (NMO) is a disease of the central nervous system that affects the optic nerves and spinal cord.Maureen Mealy, of Johns Hopkins University and colleagues investigated the association between low serum vitamin D levels and recurrent spinal cord disease. They analyzed data on vitamin D levels among 77 patients with monophasic (having only one phase or stage) and recurrent inflammatory diseases of the spinal cord, adjusting for season, age, sex, and race. The study found that vitamin D levels were significantly lower in patients who developed recurrent spinal cord disease."Our findings suggest that there may be an association between lower total 25-hydroxyvitamin D levels in patients with recurrent TM/NMO/ spectrum disorders as compared with their counterparts with monophasic disease," the authors report. They suggest that future studies are needed to further assess the relationship between vitamin D and recurrent spinal cord disease.
