BEIJING, Oct. 20 (Xinhuanet) -- A Teenager's intelligence is not fixed as usually thought. Instead, it can go through swings in a few years, according to a British study reported online in Nature.Teenagers' IQ can rise or fall 20 points over time, researchers from Wellcome Trust Centre for Neuroimaging of Kings College, showed in their study.IQ (short for "intelligent quotient") is an gauge of mental capability measured through a series of standardized tests of language skill, spatial ability, arithmetic, memory and reasoning.To get the findings, Cathy Price, senior researcher of the study, and her colleagues tested 33 British teenagers between the ages of 12 to 16 in 2004, who had average IQ scores around 100. Then the teenagers were retested four years later.The researchers found the volunteers' IQ scores went up and down over the four years, with some teenager's scores rising by as many as 20 points, and others' dropping by the same points."That is quite astounding," cheered psychologist Robert Plomin from the same university but not involved in the study. Dr. Price and her colleagues don't know the causes of such fluctuations in the scores they tested, but speculate that learning experiences might account the changes, reported by the Wall Street Journal Today. "We have to be careful not to write off poorer performers at an early stage when in fact their IQ may improve significantly given a few more years," stated Dr. Price cited by the Huffington Post.

BEIJING, Dec. 12 (Xinhua) -- A Foreign Ministry spokesman said on Monday that China welcomes the EU's new measures for coping with the European sovereign debt crisis worked out at the recently-concluded EU summit."We hope relevant measures can help stabilize the market, boost confidence in the market, stop the crisis from worsening, promote employment and economic growth, and push forward European integration," Foreign Ministry Spokesman Liu Weimin said at a routine press briefing.Last Friday at the summit in Brussels, EU leaders agreed on establishing a new "fiscal compact" based on inter-governmental treaties rather than the expected EU treaty changes. Britain opted out of the compact.Under the fiscal compact, member states will have to submit their draft budgetary plans to the European Commission, the EU's executive arm.As world's largest economy, the stable and healthy growth of the European Union and the Eurozone will be crucial to maintaining the momentum of recovery in the world economy, Liu said.China will maintain its support for EU integration, and continue to back the EU's efforts in combating the debt crisis in various ways, so as to jointly promote the stability of the international financial market and the recovery and growth of the world economy, he said."We are confident in Europe and the Eurozone, and believe that the EU has the ability and wisdom to resolve the sovereign debt crisis," Liu said.

CAPE TOWN, Dec. 15 (Xinhua) -- More people voluntarily get HIV tests in the Western Cape province, an indication of people's rising awareness of the epidemic, authorities said on Thursday.Nearly 11,000 people in the province have been tested over the past 10 days as authorities stepped efforts to halve the number of HIV transmissions over the next few years, according to official figures.Authorities expect more people to be tested when the monthly campaign ends by the end of December.In December last year, 67,111 people were tested.This year's figure is expected to be higher than that of last year, said Western Cape Premier Helen Zille.The campaign, known as Know Your Status and Win, may become a regular feature in the province, said Zille.To encourage more people to take part in the campaign, the province offers awards to several winners by drawing, ranging from 10,000 rand (about 1,250 U. S. dollars) to 50,000 rand (about 6, 250 dollars)."The bottom line is that people respond to incentives," said Zille, who hailed the campaign a success.She said the reality was that those who stubbornly did not want to get tested, were those crucially in need of doing so.While the data still had to be audited, preliminary results indicated a spike in the number of people who were tested.There was also a significant increase at routine testing center that were not part of the campaign, said Zille. Of 22.9 million HIV positive people in sub-Saharan Africa, 5.6 million in South Africa, according to an annual report by UNAIDS.

WASHINGTON, Oct. 13 (Xinhua) -- U.S. researchers have corrected sickle cell disease in adult laboratory mice that had been bred to have the inherited blood disorder by activating production of a special blood component, according to a study published online Thursday in the journal Science.Sickle cell disease results from an abnormality in hemoglobin, the protein found in red blood cells that is responsible for transporting oxygen throughout the body. People living with sickle cell disease have two copies of an altered gene that produces sickle hemoglobin instead of normal adult hemoglobin. Sickle hemoglobin changes shape after releasing its oxygen, causing the red blood cell to become stiff, misshapen and sticky, and slowing blood flow to tissues. This process damages organs and causes pain.The study tested a new approach to increasing the production of a third form of hemoglobin -- fetal hemoglobin. Production of fetal hemoglobin predominates before birth, but turns off thereafter as adult hemoglobin production takes over. People with sickle cell disease are unable to make normal adult hemoglobin, and instead make sickle hemoglobin starting in infancy.An elevated level of fetal hemoglobin within the red blood cell reduces the tendency of sickle hemoglobin to change the shape of red blood cells. Considerable research has shown that the drug hydroxyurea increases production of fetal hemoglobin and reduces the number of pain crises and other complications of sickle cell disease in adults and children. However, not all patients respond well to hydroxyurea, and adverse side effects are a concern.The current study explores a more targeted approach to increasing fetal hemoglobin production. It builds upon earlier studies that discovered a protein called BCL11A normally suppresses the production of fetal hemoglobin soon after birth. The researchers viewed the BCL11A protein as a target for therapy and decided to see what would happen if they blocked production of the protein.The paper details how the research team silenced the mouse gene that produces the BCL11A protein in mice with sickle cell disease. Silencing the gene turned off production of the BCL11A protein and allowed the adult mice to continue to produce fetal hemoglobin. It appears to have eliminated disease symptoms without affecting other aspects of blood production."This discovery provides an important new target for future therapies in people with sickle cell disease," said Susan Shurin, acting director of the U.S. National Heart, Lung, and Blood Institute, which co-funded the study. "More work is needed before it will be possible to test such therapies in people, but this study demonstrates that the approach works in principle."Approximately 100,000 Americans live with sickle cell disease. It is most prevalent in people of African, Hispanic, Mediterranean, and Middle Eastern descent. There is no widely available cure for sickle cell disease. Bone marrow transplants have cured some patients, but the treatment is not without risk and most patients do not have relatives who can donate compatible and healthy bone marrow to them.

VIENNA, Dec. 10 (Xinhua) -- China is one of the active supporters of the international community to European crisis settlement, Chinese Vice Foreign Minister Fu Ying said here on Saturday.Attending the fourth World Policy Conference, she voiced the hope that Europe could expand the mutually beneficial cooperation between Europe and China, and create a favorite condition for attracting investment from developing countries including China.In the afternoon, Fu attended a seminar with the topic of "Europe as a laboratory for global governance" and answered questions from the attendants.Asked if China and other BRICS countries should "rescue" Europe or not, she said that the word "rescue" often used by the European media could be misleading.She said that as the world's largest economy, the European Union (EU) has strong real economy and much higher living standard than developing countries. Europe does not need a "savior" but international partners with a win-win relationship.Currently, Europe is facing severe challenges such as the debt crisis and is actively seeking solutions. The EU is China's largest trading partner and one of the main sources of technology and investments. The settlement of crisis in Europe is closely related with not only the world but also China.China has been expressing its confidence in the European economy and the euro, believing that Europe is able to find out solutions to the problems, she said.She also pointed out that the current financial cooperation between Europe and China was mentioned in the same breath with the European financial expansion in Asia in the early 20th century by some European media, which was really a tale of a tub.China sticks to the foreign policy of promoting peace, development and cooperation, and has no intention to control European countries through financial tools, she said.Regarding to the role China played in the settlement of the current European debt crisis, Fu pointed out that China has been an active part of the international community supporting Europe to overcome its crisis.In addition to the cooperation in the financial sector, China also expands its imports, exploring ways to strengthen the investments in Europe and helping create jobs and restore economic growth, according to her.In her speech, she also said that in the process of industrialization, technological innovation, as well as in the fields such as green economy, Europe has always been a leading player in the world.After World War II, European countries learned from their mistakes and started the integration process to create lasting peace. The EU has been successful in maintaining regional peace and promoting economic prosperity. The governance experience in Europe is useful to other regions of the world.However, the European experience should not be completely copied by other regions due to their unique history and real situations.
