BEIJING, Sep. 16 (Xinhuanet) -- Government incentives are important to pave a low-carbon road to economic growth, but companies that improve their industry models and technologies are the main players and also benefit receivers, noted officials and industry insiders at the Summer Davos forum held in Dalian on Sep 14."The most important thing is to have the right direction," said Gao Jifan, chairman and CEO of Trina Solar, a national leading solar panel manufacturer in China.According to Gao, new energy solutions such as solar power, is the "right direction" of future growth, although many deficiencies still exist today. "As long as we have the direction correct, we can succeed as last. But this also requires policies, technologies and investment," he said.Malini Mehra, founder and CEO of the Centre for Social Markets, a non-profit organization that promotes sustainability, said there are two ways in which the governments can support low-carbon businesses to continue along a "green" path."The first is to provide some means of recognizing their good work," she said. And the second is building a measuring system to "verify which company is actually doing well, not just talking about doing well".Preferential policies are only the foundation, said Gao. "We must have a good overall plan along with advanced technologies to bring value back to the investors."Gao envisions that most of the world’s families will have "zero-consumption" houses with energy supply and storage systems relying purely on solar power by 2020.Without grid limitations, the technology can be used everywhere in the world, especially in the less developed areas."The cost of solar technologies has been on the decline over the past few years because of policy incentives and innovations of companies around the world," said Gao.A solar panel producing one watt’s electricity cost in 2005, but now it is reduced to only .2 to .3, he explained."This is the result of technological innovations and large-scale manufacturing. And it makes us more confident to see the solar energy to become a major part of the energy system in the future."Being low-carbon also helps a company attract clients because it is the current fashion and customers are more likely to choose low-carbon products, noted Klaus Kleifeld, CEO of the US aluminum products maker Alcoa Inc."The generation that we recruit today has a very different social consciousness and standards," he said. "They want to see and only want to work for companies that are sustainable."

LOS ANGELES, June 5 (Xinhua) -- A latest study has found no evidence that screening for ovarian cancer may reduce the risk of dying from the disease, it was reported on Sunday.Screening, however, does increase the likelihood of unnecessary invasive procedures, according to researchers at the University of Utah.The researchers presented their findings at an on-going meeting of the American Society of Clinical Oncology in Chicago, The Los Angeles Times said.Researchers studied 78,216 women, ages 55 to 74, who participated in the National Cancer Institute's Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. Half of the women received the usual care from their OB-gyns, and half received a CA 125 screening every year for six years and an ultrasound every year for four years. They were then followed for a maximum of 12 years.The researchers observed 212 ovarian cancers in the screened group and 176 in the normal care group. There were 118 ovarian cancer deaths in the screened group and 100 in the normal care group. The differences were not statistically significant. Overall, there were 2,924 deaths from all causes in the screened group and 2,914 in the normal care group.But the researchers also observed that 3,285 women had false- positive diagnoses from the screening. Among those, 1,080 underwent surgery that included an oophorectomy (surgical removal of one or both ovaries). Fifteen percent of those who had surgery developed major complications as a result. Overall, 1,771 women in the screened group (7.7 percent) had an oophorectomy, compared with 1,304 in the normal care group (5.8 percent)."We conclude that annual screening for ovarian cancer ... does not reduce disease-specific mortality in women at average risk for ovarian cancer but does increase invasive medical procedures and associated harms," the researchers said in the study.New data presented at the meeting also showed that the widely used cancer drug Avastin can improve treatment of ovarian cancer, The Times said.About 21,880 American women are diagnosed with ovarian cancer each year and about 13,850 die from it, according to the American Cancer Society. Because it produces few symptoms, the disease is typically not diagnosed until it has become advanced and spread throughout the body. As a result, five-year survival is only about 30 percent, and the disease is one of the five most deadly cancers among women. Being able to detect the cancer at an earlier stage when it might be more curable could thus, theoretically, improve the survival rate.The tests most commonly used to detect ovarian cancer include a transvaginal ultrasound to look for tumor masses and a blood test that screens for increased levels of a tumor marker called CA 125.

SAN FRANCISCO, July 21 (Xinhua) -- Microsoft Corp. on Thursday posted strong quarterly earnings in its fourth fiscal quarter, with profit and revenue beating expectations from Wall Street analysts.For the quarter ended June 30, the world's largest software maker reported a net income of 5.87 billion U.S. dollars, or 69 cents per share, representing increases of 30 percent and 35 percent respectively when compared with the year-ago period.Revenue for the quarter was 17.37 billion dollars, up by 8 percent from the same period a year earlier.Wall Street analysts had expected a profit of 58 cents per share on a revenue of 17.23 billion dollars, according to Thomson Reuters.For the whole fiscal year, Microsoft reported a record revenue of 69.94 billion dollars, a 12 percent increase from the prior fiscal year. Net income for the year was 23.15 billion dollars, accounting for an increase of 23 percent.Among its business sectors, Microsoft Business Division revenue grew 7 percent for the fourth quarter and 16 percent for the full year. Over 100 million licenses of office 2010 have been sold so far, said the company.Primarily driven by growth in search revenue, the company's on- line services division revenue grew 17 percent for the fourth quarter and 15 percent for the full year. U.S. search share of Microsoft's search engine Bing increased 340 basis points year- over-year.Microsoft said revenue of entertainment and devices division grew by 30 percent for the quarter and 45 percent for the year.However, Windows and Windows Live revenue declined by 1 percent for the fourth quarter and decreased by 2 percent for the full year. Microsoft said estimated full-year revenue growth for the Windows division was in line with the sluggish PC market growth.

BEIJING, July 26 (Xinhuanet) -- Hong Kong scientists announced that they had determined the idea of time travel is impossible by proving nothing can travel faster than the speed of light.The finding is contained in a study done by a research team from Hong Kong University of Science and Technology. The study was published Monday in a scientific journal "Physical Review Letters" in the United States."The study, which showed that single photons also obey the speed limit c, confirms Einstein's causality, that is, an effect cannot occur before its cause," the university said on its website."By showing that single photons cannot travel faster than the speed of light, our results bring a closure to the debate on the true speed of information carried by a single photon." said Professor Du Shengwang, who led the study.The possibility of time travel was raised 10 years ago when scientists discovered the optical pulses in some specific medium might propagate information in a faster-than-light speed."Our findings will also likely have potential applications by giving scientists a better picture on the transmission of quantum information." Du said.

HONG KONG, Sept. 9 (Xinhua) -- The Hong Kong Polytechnic University (PolyU) announced Friday that its surveying experts had successfully developed methodologies for precise mapping of the Moon, after intensive analysis of the data captured by the Chinese lunar orbiter ChangE-1 and other lunar exploration missions.According to the PolyU, the team has made significant contributions to lunar mapping. Their efforts culminated in the development of a unique and innovative approach to the creation of accurate 3D models of the lunar surface.The team has produced the most updated parameters of the lunar figure (the shape of the moon), which is essential for lunar mapping using 17.5 million laser altimetry measurements from the ChangE-1and the Japanese SELENE missions.In addition, they also used the new topographic and gravity models to calculate improved crustal thickness and mass distribution of the Moon and established that the average thickness of the Moon's crust is about 40 km on the near side and 50 km on the far side.It was introduced that the resulting lunar mapping was the hard work of a dedicated research team led by Professor Chen Yong-qi, Emeritus Professor of the Department of Land Surveying and Geo-Informatics, who is also serving on the Expert Committee of China's Lunar Exploration Programme (ECCLEP), with the concerted efforts of team members Prof. Chen Wu, Prof. Ding Xiao-li, Prof. Baki Iz, Dr. Bruce King, and Dr. Wu Bo.According to Chen Yong-qi, the lunar mapping project started in 2006. The primary objective was to develop the methodologies and techniques for mapping the Moon surface, which is much more challenging than mapping the Earth's surface because of very few surveyed control points which are essential for accurate map making.Statistics showed that there were only fourteen lunar laser ranging retro reflectors (LRRR) and Apollo lunar surface experiment package (ALSEP) transmitter sites with accurately known coordinates available only on the near side of the Moon, installed by the U.S. Apollo and former Soviet Union Luna missions in the 1960s.Moreover, according to the team, the gravitational field of the Moon is not as well-known as that of Earth, which means the accuracy of the computed lunar satellite's position at any given time is lower than for Earth satellites, thus degrading the mapping accuracy and reliability.In addition, the team expressed that highly reflective lunar surface created significant problems for the automatic processing of images to develop 3D models using the technique of photogramemtry, which is a widely used and highly reliable technique for the creation of maps and 3D models on Earth.Furthermore, the team also revealed they had a plan to compare such data with other data sources in order to evaluate the performance of the ChangE mapping sensors. Since Chen Yong-qi is serving on the ECCLEP, the team has direct access to more recent data captured by the ChangE satellite.
