WASHINGTON, Oct. 19 (Xinhua) -- A total of 25 people have been killed in 12 U.S. states in a listeria outbreak traced to Colorado cantaloupes, the U.S. Centers for Disease Control and Prevention ( CDC) said Wednesday.The number of people sickened by the tainted cantaloupes has reached 123 in 26 states, with Pennsylvania reporting its first case. One of the ill patients, a pregnant woman, suffered a miscarriage, the CDC said in a telebriefing.The listeria outbreak has been the most deadly one since 1998, according to the CDC.Listeria is a common bacterium that typically causes mild illness in healthy people, but can cause severe illness in older people and those with compromised immune systems. It also can cause miscarriages and stillbirths in pregnant women and severe infections in new babies.The CDC estimates that about 48 million people in the U.S. each year get sick from tainted food, with about 128,000 hospitalized and 3,000 deaths.

SYDNEY, Nov. 10 (Xinhua) -- Children with fat fathers are more likely to be obese by age of eight or nine than those with healthy weight fathers, a new study by researchers at Australia's University of Newcastle found on Thursday.Researchers at the University of Newcastle found that children who had an overweight or obese dad were four times more likely to follow in their father's footsteps than those with a dad in the healthy weight range.They also found in the study that only having an obese or overweight mum in the family did not have the same effect.Lead researcher Emily Freeman said it was still unknown why overweight dads had such a significant effect on their children's weights.The researchers conducted their study using data collected from 3000 Australian families between 2004 and 2008 for a longitudinal study.They looked at the weights of children when they were aged four to five and then again when they turned eight and nine years old.According to Freeman, around 25 percent of Australian children are overweight or obese.She said helping fat dads lose weight could make a difference to the youngsters.

BEIJING, Dec. 19 (Xinhua) -- China will launch its first-ever high-resolution geological mapping satellite for civil purposes next January, according to official sources.The Ziyuan III satellite will be launched aboard a Long March 4B carrier rocket from the Taiyuan Satellite Launch Center in northern China's Shanxi province, according to a conference held on Monday for the directors of surveying, mapping and geoinformation administrations across the nation.The Ziyuan III's surveying covers the entire area between 84 degrees north latitude and 84 degrees south latitude.The satellite will be used to conduct geological mapping, carry out surveys on land resources, help with natural disaster-reduction and prevention, and lend assistance to farming, water conservation, urban planning and other sectors.The Ziyuan III satellite project was inaugurated on March 2008, and also includes gravity satellites, radar satellites and follow-up satellites for the Ziyuan III, so as to obtain geoinformation under all kinds of meteorological conditions. 

BEIJING, Jan. 10 (Xinhua) -- China's energy chief said here Tuesday that the country is under greater pressure to ensure energy supply this year as both demand and international competition for resources grows.Liu Tienan, head of the National Energy Administration (NEA), made the remarks when speaking at a national energy work conference."It is always worrisome to have to sustain supply of energy and resources for a country with 1.3 billion people," Liu said.As China is facing a "grim situation" in energy saving and emission reduction, Liu noted, it is urgent to restructure the country's energy use and control the gross consumption volume this year.To ensure a stable energy supply, China will optimize the layout of energy exploration, start construction of energy-transmission projects and other major energy programs while boosting reserves of oil, natural gas and coal in 2012, Liu said.The NEA plans to add another 200 metric tons to the country's coal-producing capacity this year plus 70 million kw of new installed power-generating capacity.If the ecology is protected and people are relocated, China will start construction of hydropower projects of 20 million kw in 2012, according to the NEA.Once safety is ensured, nuclear power will be developed after the country's new safety plan is approved.As for renewable energy development, the NEA plans to launch wind power projects with a total capacity between 15 million kw and 18 million kw, while developing 3 million kw of solar power over the new five-year period ending 2015.Liu said, in 2012, the country aims to provide electricity to another 600,000 people who currently have no access to it and expand electricity access to 5 million people by 2015.The NEA has budgeted 65 billion yuan (10.3 billion U.S. dollars) for upgrading the grids in rural areas.Over the next four years, China will facilitate the development of non-conventional natural gas, such as shale gas and coalbed methane by increasing the number of natural gas users by 100 million to 250 million.A key indicator measuring the economic vitality, power consumption rose 11.7 percent year-on-year to 4.7 trillion kWh in China in 2011. The growth in 2012 is expected to slow to 8.5 percent amid the country's economic slowdown.

SINGAPORE, Oct. 10 (Xinhua) -- A Singapore start-up firm has devised an innovative application to allow phone users to have access to their positioning information within buildings, where traditional global positioning system has often proved inaccurate, local daily Business Times reported on Monday.The firm YFind Positioning System feels that the application can help turn Singapore into the world's first location- intelligent city.Ting See Ho, co-founder of the firm, said the application works by first verifying the GPS coordinates to identify the building the user is in, and then collecting RSSI (received signal strength information) readings off WiFi access points within the building.The information is then sent by the phone to the central positioning server for comparison against records of the radio map of the building, which is calibrated earlier by the company.Ting said the RSSI readings continually fluctuates, making it difficult to estimate a position. This is where YFind Positioning System steps in with its patent-pending probabilistic algorithms to help accurately estimated the user's indoor positions.Once the phone application determines the location, then, it is able to map a course for a shop or other destination within the building where the user wants to go."You can think of it as creating an 'indoor GPS' environment in the buildings where satellite signals cannot be read," Ting said.He said that more than ten organizations in Singapore have approached the company to discuss deployment and partnerships and that it has begun work on three proof-of-concepts.The company's immediate goal is to make Singapore the world's first location-intelligent city before going to other cities, he said.
