BEIJING, July 27 (Xinhuanet) -- Amazon.com’s e-book reader Kindle 3G with special offers is now the company’s top-selling e-book device, according to media reports on Wednesday.Amazon revealed in its quarterly earnings report that the ad-supported version costs 139 U.S. dollars,  50 dollars cheaper than the comparable Kindle 3G, and costs the same as a Kindle with Wi-Fi connectivity. Many believe Kindle is the most popular dedicated e-book device on the market today.The advertisements will appear only in screensavers (which appear when the reader is in an idle state) and at the bottom of the home screen, so they don’t interrupt readers.“Since AT&T agreed to sponsor screensavers, Kindle 3G with Special Offers is now our bestselling Kindle device,” Amazon’s press release said.Having zoomed past the earlier Sony Reader, and kicked off a wave of competition including the Barnes & Noble Nook and the Kobo E-Reader, Kindle is believed the most popular dedicated e-book device on the market today.

THE HAGUE, June 24 (Xinhua) -- Bird flu was discovered at a poultry farm in the central Dutch province of Flevoland, the Ministry of Agriculture said Friday.It said the virus discovered was a mild variant. The farm's 47,000 chickens were slaughtered to prevent the virus turning into a contagious and deadly variant.It remains uncertain whether the chickens were infected with the high or low pathologene H7 variant. The low pathologene version can mutate into a high pathologen, which is extremely transmittable.Poultry from other farms in a zone of three kilometres of the contaminated farm will be tested. A prohibition of transport for poultry, eggs and poultry manure has been set.

LOS ANGELES, Sept. 10 (Xinhua) -- Scientists at the University of California Los Angeles campus have announced that they have successfully used new prediction algorithms to forecast climate up to 16 months in advance.Professor Michael Ghil said in a UCLA news release Friday his team used new prediction algorithms based on matching ocean temperature records with new theories on how long-term climate trends are influenced by short-term weather extremes.That's twice as far into the future as previously accomplished.Ghil, a distinguished professor of climate dynamics in the UCLA Department of Atmospheric and Oceanic Sciences and senior author of the research, said the new prediction formulas will give climate experts and governments clues about long-term swings in the El Nino/La Nina oscillation in the Pacific Ocean, which drastically affects weather in the Americas, Asia and Australia.The new forecasting tool uses sea temperatures and has been tested on decades of historical data. The forecasts were then cross-checked against actual climate trends.The UCLA team also said that their 16-month forecasts were more accurate than previous forecasts that went only 8 months forward.Ghil emphasized that the forecasting tools are for climate, which is long-range, global patterns, but not for meteorology, which is short-term weather forecasting."Certain climate features might be predictable, although not in such detail as the temperature and whether it will rain in Los Angeles on such a day two years from now," said Ghil, who is also a member of UCLA's Institute of Geophysics and Planetary Physics. "These are averages over larger areas and longer time spans."The study is currently available online in the journal Proceedings of the National Academy of Sciences (PNAS) and will be published in an upcoming print edition of the journal.

BEIJING, Sept. 28 (Xinhua) -- China's top economic planner announced Wednesday that it will raise the minimum purchase prices for wheat from farmers in 2012 to boost grain output.The move "aims to protect farmers' enthusiasm to grow grains and further stimulate grain production," the National Development and Reform Commission (NDRC) said in a statement.The minimum purchase price for white wheat in the country's major wheat-producing areas will be increased to 102 yuan (16 U.S. dollars) per 50 kg, up 7 yuan from the 2011 price, said the NDRC.It said the minimum purchase prices for red and mixed wheat will both rise 9 yuan to 102 yuan per 50 kg next year.Wheat is one of China's major grains, which feeds its population of 1.3 billion people mainly with domestically-produced grains.A stable food supply is crucial to China's efforts to check inflation, as food prices account for about a third of the weighting in its consumer price index (CPI) calculation, a main gauge of inflation.China's CPI rose to a 27-month year-on-year high of 6.5 percent in July and weakened slightly to 6.2 percent in August.The country's grain output rose 2.9 percent last year to 546.41 million tonnes, marking the seventh consecutive year of output growth.The Ministry of Agriculture expects the output to reach a record high of 550 million tonnes this year.

CANBERRA, Aug. 29 (Xinhua) -- Alzheimer Australia on Monday released a GPS device for people with dementia, in a move to give them greater independence, while reducing the burden of missing person searches for police.The technology has been using in New South Wales of Australia, and is now available for people in state Victoria.The Safe2Walk locater can be worn by people with dementia on a lanyard around the neck or clipped onto a belt. Families can log- on to the connected website and see where the person is.The device updates the person's location every 60 seconds, reducing stress for carers so they know when a person with dementia might be wandering.It also works as a mobile phone, letting the person wearing the device to make instant calls to family.According to Alzheimer's Australia's research manager Jason Burton, the device aimed to stop vulnerable people getting lost, with research showing about 40 percent of people with dementia went missing at least once."In 99 percent of cases the carer has gone to pick them up, but there was one case where they couldn't and the police were able to contact us to get the exact GPS location of this person to rescue them," Burton told Herald Sun.A Victoria Police spokeswoman said while it could not endorse a specific product, if the device could alert carers when a person with dementia first became disorientated, the response could help avoid a large-scale police search.Mina Sapounakis, who's father has worn the Safe2Walk device, said it has given her family a sense of calm."We could go grocery shopping without stressing and rushing back home quickly to check on Dad," she said."There were a few times he had gone wandering and we were able to easily find him without having to call the police."The Safe2Walk GPS costs under 15 U.S. dollars a week for rent.
