BEIJING, Jan. 31 (Xinhua) -- The Ministry of Culture, along with seven other central departments, announced on Monday the launching of the "parental watch project" in the online games industry beginning March 1.The project will require online game companies to set up a web page, enquiry hotline and other special channels for parental supervision of their children.Besides, these companies shall authorize parents, who want to monitor and control their children playing online games, to take measures to limit or ban the playing.Also, the online game companies shall provide help to parents in supervising their children's online game accounts and preventing them from playing improper games, as part of the project.The culture ministry tested the project in several online game companies in Feb last year, which proved effective in helping juveniles overcome addictions to online games.

WASHINGTON, May 17 (Xinhua) -- The U.S. National Aeronautics and Space Administration (NASA) announced Tuesday that the international Aquarius/SAC-D observatory will be launched on June 9, to study interactions between ocean circulation, the water cycle and climate by measuring ocean surface salinity.Engineers at Vandenberg Air Force Base in California are performing final tests before mating the satellite to its Delta II rocket. The mission is a collaboration between NASA and Argentina' s space agency, with participation from Brazil, Canada, France and Italy.In addition to Aquarius, the primary instrument, the observatory carries seven other instruments that will collect environmental data for a wide range of applications, including studies of natural hazards, air quality, land processes and epidemiology.The mission will make NASA's first space observations of the concentration of dissolved salt at the ocean surface. Aquarius' observations will reveal how salinity variations influence ocean circulation, trace the path of freshwater around our planet, and help drive Earth's climate. The ocean surface constantly exchanges water and heat with Earth's atmosphere. Approximately 80 percent of the global water cycle that moves freshwater from the ocean to the atmosphere to the land and back to the ocean happens over the ocean.Salinity plays a key role in these exchanges. By tracking changes in ocean surface salinity, Aquarius will monitor variations in the water cycle caused by evaporation and precipitation over the ocean, river runoff, the freezing and melting of sea ice. Salinity also makes seawater denser, causing it to sink, where it becomes part of deep, interconnected ocean currents. This deep ocean "conveyor belt" moves water masses and heat from the tropics to the polar regions, helping to regulate Earth's climate."Salinity is the glue that bonds two major components of Earth' s complex climate system: ocean circulation and the global water cycle," said Aquarius Principal Investigator Gary Lagerloef of Earth & Space Research in Seattle in a statement. "Aquarius will map global variations in salinity in unprecedented detail, leading to new discoveries that will improve our ability to predict future climate."Aquarius will measure salinity by sensing microwave emissions from the water's surface with a radiometer instrument. These emissions can be used to indicate the saltiness of the surface water, after accounting for other environmental factors. Salinity levels in the open ocean vary by only about five parts per thousand, and small changes are important. Aquarius uses advanced technologies to detect changes in salinity as small as about two parts per 10,000, equivalent to a pinch (about one-eighth of a teaspoon) of salt in a gallon of water.Aquarius will map the entire open ocean every seven days for at least three years from 408 miles (657 kilometers) above Earth. Its measurements will produce monthly estimates of ocean surface salinity with a spatial resolution of 93 miles (150 kilometers). The data will reveal how salinity changes over time and from one part of the ocean to another.

WASHINGTON, May 20 (Xinhua) -- The U.S. Food and Drug Administration (FDA) on Friday approved Sutent to treat patients with progressive neuroendocrine cancerous tumors located in the pancreas that cannot be removed by surgery or that have spread to other parts of the body.Neuroendocrine tumors found in the pancreas are slow-growing and rare. It is estimated that there are fewer than 1,000 new cases in the United States each year.This is the second new approval by the FDA to treat patients with this disease. On May 5, the agency approved Afinitor."FDA believes it is important to provide cancer patients with as many treatment options as possible," said Richard Pazdur, director of the Office of Oncology Drug Products in the FDA's Center for Drug Evaluation and Research. "The agency is committed to working with companies to bring innovative new therapies to the market and encourages companies to continue exploring additional uses for approved products."The safety and effectiveness of Sutent was established in a single study of 171 patients with metastatic (late-stage) or locally advanced (disease that could not be removed with surgery) disease who received Sutent or a placebo (sugar pill). The study was designed to measure the length of time a patient lived before their disease spread or worsened (progression-free survival).Results from the study demonstrate that Sutent provided benefit to patients by prolonging the median length of time they lived without the cancer spreading or worsening to 10.2 months compared to 5.4 months for patients who received placebo.In patients treated with Sutent for neuroendocrine pancreatic tumors, the most commonly reported side effects included diarrhea, nausea, vomiting, fatigue, anorexia, high blood pressure, energy loss, stomach pain, changes in hair color, inflammation of the mouth, and a decrease in infection-fighting white blood cells.Sutent is marketed by New York City-based Pfizer.

BEIJING, Feb. 5 (Xinhua) -- China's meteorological authority said Saturday that a cold snap would sweep north China over the next few days, bringing down temperatures and carrying gusty winds.Temperatures in some parts of Xinjiang Uygur Autonomous Region, Inner Mongolia Autonomous Region and northeast China will drop 4 to 6 degrees Celsius over the weekend, the National Meteorological Center (NMC) said in a statement on its website.In most areas north to the Huaihe River, the temperatures will go down 4 to 6 degrees Celsius, or even 8 to 10 degrees Celsius in some parts of the areas between Monday and Tuesday.The cold front would then move southward to affect more areas in the eastern and southern parts of the country.The NMC said some areas in northern and western Xinjiang Uygur Autonomous Region, the eastern part of Inner Mongolia, Sichuan Basin and most of the northeast China, the western parts of the areas south to the Yangtze River will see light to moderate snow or sleet in the forthcoming three days.Fog continued to shroud south China Saturday, reducing visibility to less than 200 meters in parts of Hunan, Hubei, Jiangxi, Sichuan and Fujian provinces, as well as Chongqing City.

WASHINGTON, May 11 (Xinhua) -- Johns Hopkins University researchers have demonstrated that human liver cells derived from adult cells coaxed into an embryonic state can engraft and begin regenerating liver tissue in mice with chronic liver damage.The work, published Wednesday in the journal Science Translational Medicine, suggests that liver cells derived from so- called "induced-pluripotent stem cells (iPSCs)" could one day be used as an alternative to liver transplant in patients with serious liver diseases, bypassing long waiting lists for organs and concerns about immune system rejection of donated tissue."Our findings provide a foundation for producing functional liver cells for patients who suffer liver diseases and are in need of transplantation," says Yoon-Young Jang, assistant professor of oncology at the Johns Hopkins Kimmel Cancer Center. "iPSC-derived liver cells not only can be generated in large amounts, but also can be tailored to each patient, preventing immune-rejection problems associated with liver transplants from unmatched donors or embryonic stem cells." A microsopic view shows human embryonic stem cells in various stages of differentiation into liver cells in this photo taken at Stanford University and released by the California Institute for Regenerative Medicine, March 9, 2009iPSCs are made from adult cells that have been genetically reprogrammed to revert to an embryonic stem cell-like state, with the ability to transform into different cell types. Human iPSCs can be generated from various tissues, including skin, blood and liver cells.Although the liver can regenerate in the body, end-stage liver failure caused by diseases like cirrhosis and cancers eventually destroy the liver's regenerative ability, Jang says. Currently, the only option for those patients is to receive a liver organ or liver cell transplant, a supply problem given the severe shortage of donor liver tissue for transplantation. In addition, mature liver cells and adult liver stem cells are difficult to isolate or grow in the laboratory, she says. By contrast, iPSCs can be made from a tiny amount of many kinds of tissue; and the embryonic stem- like iPSCs can grow in laboratory cultures indefinitely.For the study, Jang and colleagues generated human iPSCs from a variety of adult human cells, including liver cells, fibroblasts ( connective tissue cells), bone marrow stem cells and skin cells. They found that though the iPSCs overall were molecularly similar to each other and to embryonic stem cells, they retained a distinct molecular "signature" inherited from the cell of origin.
