ISTANBUL, May 3 (Xinhua) -- The world's water consumption will increase by 40 percent over the next two decades and efforts to meet this demand must increase radically, the secretary-general of the 5th World Water Forum said here on Tuesday.Oktay Tabasaran said in his opening speech at the World Water Forum that "water consumption will increase by 40 percent in the coming 20 years, reaching 6.9 trillion cubic meters per year ( compared with the 4.5 trillion used currently), and an amount of 200 billion U.S. dollars must be spent annually in order to afford this."He said such figures indicated the urgent need for countries to engage in efficient cooperation with each other to address water- related issues.Some 50 out of the world's 188 countries have serious concerns in providing drinking and irrigation water, due to careless and inefficient use of water, according to Ismail Ugur, the general director of Turkey's State Waterworks Authority."If we fail to come up with solutions, starting from 2015 there will be droughts (in many parts of the world) and people will start suffering from diseases caused by lack of water, as of 2025, " Ugur said.Ekmeleddin Ihsanoglu, head of the Organization of the Islamic Conference (OIC), said that ensuring reliable access to water is crucial to promoting peace and security in the Middle East, where many countries are facing dramatic declines in available water."In some regions of the Muslim world, water availability is predicted to be cut in half by 2050, even without taking into consideration the effects of climate change," he said in his opening speech.The OIC chief called for increased cooperation among member states and countries outside the region, announcing the group's progress in preparing its own "Water Vision" document and forming an OIC Water Council to address water-related concerns."In its first phase, the Water Vision will outline a framework of cooperation on water-related issues in terms of water-sharing experience, capacity development, technology transfer, water governance and institutional reforms," Ihsanoglu said.He cited the Friendship Dam, to be constructed on the Orontes River at the Turkish-Syrian border, as an excellent example of cooperation and peace among neighboring countries in the field of water.Charity Ngilu, minister for water and irrigation of Kenya, stressed the importance of water in promoting peace, especially in regions where water scarcity prevails."There have been many conflicts caused by water scarcity not only among African countries, but even within regions of the same country," She said, adding Kenya would ask Turkey for cooperation and assistance in water management and other related issues.

WASHINGTON, May 4 (Xinhua) -- The U.S. National Aeronautics and Space Administration (NASA) announced Wednesday that its Gravity Probe B (GP-B) mission has confirmed two key predictions derived from Albert Einstein's general theory of relativity, which the spacecraft was designed to test.The experiment, launched in 2004, used four ultra-precise gyroscopes to measure the hypothesized geodetic effect, the warping of space and time around a gravitational body, and frame- dragging, the amount a spinning object pulls space and time with it as it rotates.GP-B determined both effects with unprecedented precision by pointing at a single star, IM Pegasi, while in a polar orbit around Earth. If gravity did not affect space and time, GP-B's gyroscopes would point in the same direction forever while in orbit. But in confirmation of Einstein's theories, the gyroscopes experienced measurable, minute changes in the direction of their spin, while Earth's gravity pulled at them.The findings are available online in the journal Physical Review Letters."Imagine the Earth as if it were immersed in honey. As the planet rotates, the honey around it would swirl, and it's the same with space and time," said Francis Everitt, GP-B principal investigator at Stanford University. "GP-B confirmed two of the most profound predictions of Einstein's universe, having far- reaching implications across astrophysics research."GP-B is one of the longest running projects in NASA history, with agency involvement starting in the fall of 1963 with initial funding to develop a relativity gyroscope experiment. Subsequent decades of development led to groundbreaking technologies to control environmental disturbances on spacecraft, such as aerodynamic drag, magnetic fields and thermal variations. The mission's star tracker and gyroscopes were the most precise ever designed and produced.GP-B completed its data collection operations and was decommissioned in December 2010."The mission results will have a long-term impact on the work of theoretical physicists," said Bill Danchi, senior astrophysicist and program scientist at NASA Headquarters in Washington. "Every future challenge to Einstein's theories of general relativity will have to seek more precise measurements than the remarkable work GP-B accomplished."

SAN FRANCISCO, April 5 (Xinhua) -- The appeal of tablet computer and electronic-book reader (e-reader) has been giving a boost to semiconductor market as sales of chips for such devices surged in 2010 and keeps growing, market research firm International Data Corp. (IDC) said on Tuesday.A new IDC report showed that worldwide revenues for media tablet and e-reader semiconductors grew by over 2,000 percent to 3. 3 billion U.S. dollars in 2010 as semiconductor suppliers enabled original equipment manufacturers to bring new products to market less than 8 months after Apple Inc. launched its iPad tablet.According to IDC's definition, media tablets are devices with color displays larger than 5-inch and smaller than 14-inch, running lightweight operating systems and able to be based on either x86 or ARM processors."The opportunity for semiconductors in media tablets and e- readers has exploded and semiconductor suppliers are scrambling to bring to market semiconductor and software platforms to enable these products," Michael Palma, a senior research analyst at IDC, said in a statement.Looking forward, IDC said it expects media tablet and e-reader semiconductor revenues to grow by 120 percent year over year in 2011, predicting that the market will be boosted by the arrival of a new version of Google Inc.'s Android operating system, dual core processors and increased bandwidth."For the next several years, we will see rapid innovation cycles for products launched into the marketplace and semiconductor suppliers will continue to satisfy evolving end user requirements over the coming years," Palma noted.

BRASILIA, March 15 (Xinhua) -- A nationwide program aimed at providing internet access to 80 percent of the country's population by 2014 is forging ahead in Brazil, Communications Minister Paulo Bernardo said on Tuesday.The National Broadband Plan (PNBL), with participation of 13 ministries, is coordinated by Bernardo, who explained details about the project on Tuesday along with Joao Santana, president of Telebras, the state-owned enterprise responsible for managing the project.The authorities have criticized companies that offer internet service for failing to spread internet use in Brazil, offering an expensive service with prices amounting to about 50 U.S. dollars monthly, inaccessible to low-income families."We ended 2010 with 34 percent of Brazilian households with Internet access, and service is also very poor. Almost half of connections are of 256 mbps. We are out-of-date, with the aggravating circumstance that the connections are very expensive," Bernardo said.To speed up the process, the government started negotiating with concessionaire phone companies to improve the service quality and lower the price to about 30 reais (18 dollars), which would allow 80 percent of the population to access internet."During (former president) Lula da Silva's government, we developed a program to interconnect all schools with internet access, but we also want the private sector to do its share," he said.

WASHINGTON, April 3 (Xinhua) -- In the largest study of its kind, researchers from a consortium led by the University of Pennsylvania School of Medicine, the University of Miami, and the Boston University School of Medicine, identified four new genes linked to Alzheimer's disease. The findings appeared Sunday in the current issue of Nature Genetics.Each gene individually adds to the risk of having this common form of dementia later in life. These new genes offer a portal into what causes Alzheimer's disease and is a major advance in the field.The study, conducted by the Alzheimer's Disease Genetics Consortium, reports genetic analysis of more than 11,000 people with Alzheimer's disease and a nearly equal number of elderly people who have no symptoms of dementia. Three other consortia contributed confirming data from additional people, bringing the total number of people analyzed to over 54,000. The consortium also contributed to the identification of a fifth gene reported by other groups of investigators from the United States, the United Kingdom, France, and other European countries.The study is the result of a large collaborative effort with investigators from 44 universities and research institutions in the United States, led by Gerard Schellenberg at University of Pennsylvania."This is the culmination of years of work on Alzheimer's disease by a large number of scientists, yet it is just the beginning in defining how genes influence memory and intellectual function as we age. We are all tremendously excited by our progress so far, but much remains to be done, both in understanding the genetics and in defining how these genes influence the disease process," Schellenberg said.Until recently, only four genes associated with late-onset Alzheimer's have been confirmed, with the gene for apolipoprotein E-e4, APOE-e4, having the largest effect on risk. The Nature Genetics studies add another four -- MS4A, CD2AP, CD33, and EPHA1 -- and contribute to identifying and confirming two other genes, BIN1 and ABCA7, thereby doubling the number of genes known to contribute Alzheimer's disease.
