SAN FRANCISCO, Sept. 13 (Xinhua) -- Intel and Google on Tuesday announced a partnership to enable the world's largest chip maker's architecture on the search giant's products, saying that an Intel chip-based Android smartphone will hit the market in the first half of 2012.In a joint press release, the two companies said the future versions of Android mobile operating system will support Intel's low power Atom processors, in addition to other architectures.At the Intel Developer Forum in San Francisco on Tuesday, Intel Chief Executive Officer Paul Otellini said the Intel smartphone chip is code-named Medfield and based on the company's own PC- based computer architecture.Otellini said multiple vendors around the world will launch the Medfield-based Android smartphones in the first half of 2012.Andy Rubin, senior vice president of mobile at Google, came on stage at the close of Otellini's keynote to hail the joint initiatives between the two companies.Intel has been struggling to get a bite of the booming market of smartphones and tablets. Most of the current mobile devices use chips based on architecture from ARM Holdings, which are considered more power efficient than Intel's products. Nokia had planned to ship smartphones with Intel chips this year, but it shifted to ARM-based phones with Windows Phone 7 system.Otellini said Intel will eventually have an advantage in supplying smartphone chips as the business is not established in terms of the final winner and performance of the products keeps growing.

BEIJING, July 1 (Xinhuanet) -- China must adopt a holistic approach to addressing food safety challenges connected to the risk of contracting infectious diseases from contact with animals, the World Health Organization (WHO) has said. Peter Ben Embarek, food safety officer at WHO's China office, said the country faces risks connected to the need to produce more meat, eggs and milk to feed its growing population. He said the increased production will ramp up the risk of people being infected by food-borne diseases because of poor slaughtering oversight and the absence of proper surveillance and inspection systems. About 50 percent of pigs in China are slaughtered outside of formal facilities without the inspection of veterinarians or food safety officers. He said poorly trained producers have little or no awareness of food safety or the risk of animal diseases being passed on to humans. Such an environment could lead to the emergence of a new pandemic of influenza. During the past 60 years, 30 percent of the 335 new infectious diseases worldwide were transmitted through food, he said. Yet in many parts of China, public awareness remains low about such things. Xu Aixiang, a 35-year-old resident of Rizhao city in Shandong province, prefers to buy live poultry at local markets. Like many of her neighbors, she takes the chickens she buys home to slaughter them. "I get fresher chickens that are better quality this way," she said. "When vendors sell slaughtered chickens, the meat is no longer fresh and may have had water injected into it to make it heavier." But Ben Embarek cautioned that such live-animal markets are high-risk places for the exchange of viruses and diseases between animals and humans. He said simple and cost-effective measures can be taken to improve such markets' hygiene standards, such as the installation of separate areas to keep live poultry away from customers as well as improving air flow and waste management. Several UN agencies, including the WHO and the Food and Agriculture Organization, called on China to adopt an integrated approach to preventing emerging epidemic diseases and maintaining ecosystem integrity at an event themed "One Health" that convened on Wednesday in Beijing. At the gathering, representatives from the Ministry of Health, the Ministry of Agriculture and the Chinese Center for Disease Control and Prevention shared experiences from efforts to mitigate the H5N1 and H1N1 influenza outbreaks in China and said they were committed to working together in the future. Su Jingliang, an associate professor of preventive veterinary medicine at China Agricultural University, said his lab had detected the outbreak of a new type of flavivirus in ducks that led to a significant fall in egg production at farms in Beijing as well as in Hebei, Jiangxi and Shandong provinces. The pandemic was brought under control in March. No cases of humans contracting the disease have been reported so far but Su said he was concerned about the possibility of farmers becoming infected through close contact and long exposure to sick ducks. He said precautionary measures should be taken in cooperation with the Ministry of Health and other government agencies and checks should be run on people who are at high risk. Xu Wei contributed to this story.

WASHINGTON, Aug. 4 (Xinhua) -- Researchers have found a way to turn mouse embryonic stem cells into sperm and this finding opens up new avenues for infertility research and treatment, according to a study published Thursday in the online edition of journal Cell,A Kyoto University team coaxed mouse embryonic stem cells into sperm precursors, called primordial germ cells (PGCs), and shown that these cells can give rise to healthy sperm. The researchers say that such in vitro reconstitution of germ cell development represents one of the most fundamental challenges in biology.When transplanted into mice that were unable to produce sperm normally, the stem cell derived PGCs produced normal-looking sperm, which were then used to successfully fertilize eggs. These fertilized eggs, when transplanted into a recipient mother, produced healthy offspring that grew into fertile male and female adult mice. The same procedure could produce fertile offspring from induced pluripotent stem cells that are often derived from adult skin cells."Continued investigations aimed at in vitro reconstitution of germ cell development, including the induction of female primordial germ cell-like cells and their descendants, will be crucial for a more comprehensive understanding of germ cell biology in general, as well as for the advancement of reproductive technology and medicine," the researchers wrote.

CANBERRA, Sept. 23 (Xinhua) -- A genetic study on Friday found Aboriginal Australians are descended from the first people to leave Africa up to 75,000 years ago.Researchers from the University of Western Australia, Murdoch University and an international team analyzed genetic material of a 100-year-old West Australian Aboriginal man's hair, and found he was directly descended from a migration out of Africa into Asia.The study revealed that Australian Aboriginal ancestors split from the first modern human populations to leave Africa, between 64,000 and 75,000 years ago, at least 24,000 years before other human migrations.According to Dr. Joe Dortch, an archaeologist at the University of Western Australia, the discovery rewrites the history of the human species by confirming humans moved out of Africa in waves of migrations rather than in one single out-of-Africa diaspora.It also rewrites the story about how Aborigines arrived in Australia some 50,000 years ago."So far there are no [archaeological] sites that are over 50, 000 years old so it puts a time limit on that and focuses our future efforts," he said in a statement released on Friday.Dr. Dortch believes the finding will foster a sense of pride in modern Australian Aborigines."No-one else in the world can say 'I am descended from people who have been here 75,000 years'."Associate Professor Darren Curnoe, leader of the Human Evolutionary Biology Lab in the School of Biological, Earth & Environmental Sciences at the University of New South Wales, said the study powerfully confirms that Aboriginal Australians are one of the oldest living populations in the world, certainly the oldest outside of Africa."Australians are truly one of the world's great human populations and a very ancient one at that, with deep connections to the Australian continent and broader Asian region. About this now there can be no dispute," he told Xinhua in an email note.Meanwhile, Professor Alan Cooper, Director of the Australian Centre for Ancient DNA (ACAD) at the University of Adelaide, said while this is a major step forward, the key unresolved question remains the unique story of Aboriginal history within Australia, such as what has happened in those 50,000 years of life in the harsh Australian environment."Unfortunately, the information from a single individual tells us very little about this fascinating, and critically important part of human history. Aborigines are one of the oldest continuous human populations outside Africa, as they note in the paper, and due to the geographic isolation and limited archaeological records remain one of the most mysterious chapters in human history," he told Xinhua on Friday.The study is published on Friday in the journal Science.Indigenous Australians are the original inhabitants of the Australian continent and nearby islands. They together make up more than 2.5 percent of Australia's population.

SAN FRANCISCO, June 28 (Xinhua) -- Microsoft on Tuesday launched its cloud service Office 365, which was the software giant's answer to competing products from Google and other companies.The service includes on-line versions of Word, PowerPoint, Excel, Outlook and other Office applications, as well as Microsoft 's communication and collaboration tools such as Exchange, SharePoint and Lync.It will allow users to work on files and documents at the same time using instant messaging and video-conferencing."Where does Office meet the cloud? It's Office 365, the absolute best productivity and collaboration service for business around the world," Microsoft CEO Steve Ballmer said at a webcast event.Microsoft said that Office 365 is now available in 40 markets with choices for small and big businesses ranging from 2 to 27 U.S. dollars per user per month.Office 365 will compete directly with the web-based Google Apps, which Google sells for 50 dollars per user per year.Microsoft's service was introduced in beta last year and the company said response was enthusiastic with more than 200,000 organizations signed up and began testing it in a few months."With a few clicks, Office 365 levels the playing field, giving small and midsize businesses powerful collaboration tools that have given big businesses an edge for years," Ballmer said in a statement.
