BEIJING, March 6 (Xinhua) -- China aims to "basically eradicate poverty" by 2020 while greatly raise its poverty line, in order to help more people in need, Chinese Premier Wen Jiabao said here Sunday.The State Council is drafting a new ten-year poverty-reduction plan (2011-2020), in which the current poverty line of 1,196 yuan per year (about 0.5 U.S. dollars a day) will be greatly raised, Wen told a panel meeting of the ongoing session of the National People's Congress (NPC).The nation will intensify its poverty alleviation efforts through aids and development, focusing on large areas of destitute population, he said to a group of NPC deputies from Gansu, one of the poorest regions in China.According to the United Nations' standard of one dollar per person each day, China still has 150 million people under the poverty line.Wen said lack of water was the bottleneck for Gansu's social-economic development, urging the province to expand the use of water conservancy technology.Wen also urged the province to coordinate economic development with environmental protection, and reverse environmental degradation in Dunhuang, a historical city with world cultural heritage threatened by decertification.

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.

VIENNA, March 28 (Xinhua) -- Stress hormone is helpful in alleviating acrophobia, a morbid fear of great heights, according to a study by Austrian scientists.They published the findings in the recent Proceedings of the National Academy of Sciences of the United States of America.Frank H. Wilhelm, professor from the Department of Clinical Psychology, Psychotherapy and Health Psychology at the University of Salzburg, Austria, carried out the first study demonstrating the clinical effectiveness of hormones released at periods of high stress in anxiety.The study found hormones and other drugs could be a good addition to behavioral treatment of several anxiety disorders.People with acrophobia have formed a so-called fear memory, which could be activated when the fear-causing stimulus occurs. They tend to react with feelings of extreme fear and anxiety to the ride in a glass elevator.Hence, scientists conducted a confrontation therapy, trying to mask this memory.A total of 40 experimental subjects had been put in a safe environment to constantly confront the fear-inducing stimulus, until they had a new reaction to the perceived threat.Observations also suggested hormones released in high stress had impact on learning and memory.Additionally, stress hormones were believed to facilitate the storage of new, anxiety-free competence and experienced confidence in the therapy. Animal studies have shown that this emotional relearning benefits from cortisol, one of the stress hormones.

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.

WASHINGTON, Jan. 19 (Xinhua) -- China and the United States have agreed to further boost their bilateral relationship toward a cooperative partnership for the benefit of the whole world, President Hu Jintao said Wednesday.The visiting Chinese leader presented the course forward at a joint press conference at the White House with his U.S. counterpart Barack Obama following their eighth meeting in two years.During the talks, conducted in "a candid, pragmatic and constructive atmosphere," the two sides reached "important agreement on China-U.S. relations and major international and regional issues of shared interests," according to the Chinese president.Chinese President Hu Jintao (2nd L) holds a bilateral meeting with U.S. President Barack Obama (2nd R) at the White House in Washington, the United States, Jan. 19, 2011. "We both agree to further push forward the positive, cooperative and comprehensive China-U.S. relationship," Hu said, adding that both sides also pledged to forge "a China-U.S. cooperative partnership based on mutual respect and mutual benefit" for the benefit of the two countries and beyond.Meanwhile, the two sides "should firmly adhere to the right direction," respecting each other's core interests and handling their relations with a long-term perspective, which will enable both countries to make greater contributions to world peace and development, he said.Citing the growing number of global challenges, the Chinese president stressed that Beijing and Washington "share expanding common interests and shoulder increasing common responsibilities."Accordingly, he added, the two sides have agreed to strengthen exchanges and cooperation in economy, trade, environment, education, science and technology, non-proliferation and counter-terrorism among many other fields.During Hu's ongoing state visit, the two countries signed a number of cooperation agreements.
