KUBUQI (Inner Mongolia), July 10 (Xinhuanet) -- Amos Nadai, ambassador of Israel to China, spoke highly of the desertification control efforts in the Kubuqi desert of China during an exclusive interview with Xinhuanet here Saturday. "It's a huge area, which is more than half of my country," Nadai said, "I see a lot of planting and it's very beautiful." Nadai was here for the 2011 Kubuqi International Desert Forum held in the Kubuqi Desert, Inner Mongolia of China. As a small country with half of its land being desert, Israel has to work very hard in desertification control and has accumulated a great deal of experience. However, Nadai praised China's efforts in learning new technologies applied in the Kubuqi desert. He said that China takes this very seriously and has developed really rapidly. "They are doing the right thing; they bring here every two years the best experts from all over the world, and they listened carefully," he said. Nadai said that he saw the way people here fight against desertification, develop tourism, boost the use of clean energy, and he was very impressed. That's why Israel is happy to cooperate with China in this field, Nadai said. He also introduced a long-term project that Israel has been working together with China in Xinjiang, which Israel introduces methods to the local farmers that can grow the same amount of crop by using 50 percent less of water. "The local people have learned everything that we can offer them and they can do it alone now," Nadai said. The ambassador, who was awarded the Honorary Citizenship of Chengdu City, the capital of Sichuan Province, Wednesday, said: "I am very very excited for that honor."

BEIJING, August 1 (Xinhuanet) -- U.S. researchers have discovered a genetic mutation unique to African Americans that links to heighten their asthma risk, according to reports published on Sunday in the journal Nature Genetics.Researchers of University of Chicago found a gene, PYHIN1, and its variations may account for asthma risk in people of African descent. In their study, they examined data from nine previous genome-wide association studies, totaling more than 2 million single nucleotide polymorphisms in 3,246 asthma patients and 3,385 control patient, 1,702 patient-parent groupings, 355 family-based cases, and 468 family-based controls.In the study, the researchers found that between 26 percent and 29 percent of people of African-descent carried at least one copy of the gene.  In particular, one polymorphism of the gene was 34 percent more likely found in African-American and Afro-Caribbean people with asthma.  More interestingly, this variant of the gene is rarely found in Caucasian people and in Latino population, it was found in less than 5 percent.This new variant is part of a family of genes linked with the body's response to viral infections. It is thought to be involved in interferon signaling, which could influence the occurrence of asthma.The team stressed that each gene variant on its own plays only a small role in increasing asthma risk, but that risk could be multiplied when combined with other risk genes and with environmental factors.

WASHINGTON, Aug. 17 (Xinhua) -- Latest research shows that the Moon could be younger than previous estimates. The findings were published online Wednesday in the Nature journal.The prevailing theory of the Moon's origin is that it was created by a giant impact between a large planet-like object and the proto-Earth. The energy of this impact was sufficiently high that the Moon formed from melted material that was ejected into space. As the Moon cooled, this magma solidified into different mineral components. Analysis of lunar rock samples thought to have been derived from the original magma has given scientists a new estimate of the Moon's age.According to this theory for lunar formation, a rock type called ferroan anorthosite, or FAN, is the oldest of the Moon's crustal rocks, but scientists have had difficulty dating FAN samples. The research team used newly refined techniques to determine the age of a sample of FAN from the lunar rock that was brought back to Earth by the Apollo 16 mission in 1972.The team analyzed the isotopes of the elements lead and neodymium to place the FAN sample's age at 4.36 billion years. This figure is significantly younger than earlier estimates of the Moon's age that range as old as the age of the solar system at 4. 568 billion years. The new, younger age obtained for the oldest lunar crust is similar to ages obtained for the oldest terrestrial minerals -- zircons from western Australia -- suggesting that the oldest crusts on both Earth and Moon formed at approximately the same time, and that this time dates from shortly after the giant impact.This study is the first in which a single sample of FAN yielded consistent ages from multiple isotope dating techniques. This result strongly suggests that these ages pinpoint the time at which the sample crystallized."The extraordinarily young age of this lunar sample either means that the Moon solidified significantly later than previous estimates, or that we need to change our entire understanding of the Moon's geochemical history," Carnegie Institute of Science's geochemist and study author Richard Carlson said.

COPENHAGEN, June 7 (Xinhua) -- The outbreak of infections caused by E. coli bacteria may be over in Denmark as no new cases have been reported here since Friday.According to Denmark's National Serum Institute (NSI), there are 18 confirmed cases of severe intestinal infection caused by exposure to the bacteria as of Monday. No new infections have been reported since Friday, it added.The confirmed cases are said to consist of 10 men and 8 women aged between 23 and 81 years of age. Seven show symptoms of kidney failure which is associated with advanced stages of the infection.All but one are believed to have contracted the infection while traveling in northern Germany, where the outbreak started, the NSI said.So far, the E. coli infection has claimed 21 lives in Germany, which reports over 2,100 confirmed and suspected cases. It has also spread to 12 countries according to the World Health Organization (WHO)."This particular strain of E.coli has been identified in some people sporadically in the past, but it has not been known to have been associated with outbreaks in the past," a WHO spokesperson said Friday, adding it was a "very, very rare strain."Health authorities in Germany now suspect bean sprouts as the source of contamination in this outbreak, although this is yet to be confirmed.Dr Kaare Moelbak, an epidemiologist at NSI told Danish media Sunday that bean sprouts were a "very likely" source of contamination.Cucumbers were initially suspected and Denmark's food authority continues to warn against eating raw tomato, cucumber or lettuce from Germany until the source is established.Children are normally most vulnerable to E. coli infection but most of those infected in this outbreak are above the age of 20 years, Moelbak told Xinhua last week.He said children are likely less affected by this outbreak as they usually eat fewer salads than adults.In Germany, it is mostly women who have been affected by the infection. Moelbak explained the skew in infections saying women tend to choose to eat more vegetables than men, in comments made to Danish media Thursday.

CANBERRA, June 10 (Xinhua) -- Going to work when you are feeling sick can make you sicker in the long run, an expert told Australia's media on Friday.New Zealand sociologist Professor Kevin Dew from the Victoria University in Wellington, has assessed more than 40 papers about " presenteeism".He defined presenteeism as: "People that are turning up at work when they feel that they should be at home sick.""People feel compelled to go to work because someone else would have to take up the workload (and they have a) feeling of responsibility for not being able to care properly for patients (if they don't show up)," he told the Australia Associated Press on Friday.He said that evidence suggested people who go to work when they are sick can have long term negative effects on health and productivity.Evidence shows that presenteeism increases illness, including musculoskeletal pain, fatigue, depression, and serious coronary events. It also leads to exhaustion which, in turn, leads to more presenteeism.Prof. Dew said certain medical conditions like depression and migraine are also linked with presenteeism because they are not seen as legitimate reasons for absence.He has written an editorial in the latest issue of the British Medical Journal about his findings.
