BEIJING, Oct. 13 (Xinhuanet) -- Scientists have decoded the genome of Black Death which caused one of the worst plagues in human history.The finding was published Wednesday in the scientific journal Nature.A team of German, Canadian and American scientists collected the bacteria's DNA from ancient plague victims' teeth and bones, which were excavated from the burial ground in London.With a careful NDA comparison between the ancient bacteria and the modern strains, scientists found the direct variant of the medieval bacteria still exist today.Black Death's descendants kill around 2,000 people a year, mostly in the developing world, the scientist said."This will provide us with direct insights into the evolution of human pathogens and historical pandemics," said Johannes Krause Of Germany's University of Tubingen, who worked on the study.Black Death, the fatal plague of medieval Europe, wiped out some 30 million people -- about 50 percent of the population on the continent, within just five years, between 1347 and 1351.

BEIJING, Nov. 13 (Xinhua) -- A campaign that aims to boost the public's role in safeguarding food safety and promote awareness of the issue was launched at the 9th China Food Safety Annual Conference, which closed on Sunday.Food safety has a bearing on people's health as well as the nation's sound and harmonious development, said Shi Xiushi, chairman of the Financial and Economic Committee of China's National People's Congress (NPC), at the opening, calling for efforts to raise companies' sense of responsibility and consumers' awareness in preventing and dealing with food safety crimes.The new campaign is part of a broader five-year program (2011-2015) of food safety education announced by the State Council Food Safety Commission (SCFSC) in May.The program aims for more than 80 percent of the public to be aware of basic food safety by 2015, with the rate for primary and high-school students reaching up to 85 percent or more.ARDUOUS WORKFood safety has become a growing public concern in China following a string of scandals over recent years. In the latest one, illegal workshops were found making and selling "gutter oil," which is processed from leftovers dredged from gutters.Gu Xiulian, former vice chairwoman of the NPC's Standing Committee, the country's top legislature, said ensuring safety is the top priority for the food sector, the country's pillar industry with an output of 550 million yuan (97.3 million U.S. dollars) in the first nine months of 2011.The development of the nation's food safety has failed to keep up with the demands of a public whose living standards have improved substantially in recent years, said Shi.Pledging to do everything it can to ensure food safety, the government takes a zero-tolerance approach to companies that sell unsafe food. In 2010 alone, authorities across the country investigated and handled 130,000 cases of food safety violations, shutting down more than 100,000 companies, according to the SCFSC."The food industry's overall development level is relatively low. There are weak links in the sector's credibility, management, detection techniques and even the laws and regulations," said Pu Changcheng, deputy director of the Administration of Quality Supervision, Inspection and Quarantine.Pu's points are exemplified by China's agricultural industry, which is largely based around small-scale production managed by disparate bodies. It would be a formidable task to eradicate the sector's safety issues.The catering business also faces a similar plight. The country has issued licenses to 2.2 million catering companies, most of which are small and individually operated, making safety supervision extremely difficult, according to Bian Zhenjia, deputy head of the State Food and Drug Administration.

BEIJING, Oct. 21 (Xinhua) -- China's State Councilon Thursday called ordered improved, innovative administration in environmental protection, according to a statement.In a statement published on the central government's website, the State Council listed a series of guidelines on environment-related issues, saying that it will step efforts to address prominent environmental problems that affect people's lives and sustainable development.The statement ordered strictly implementing environmental impact assessment, vigoroulsy developing environmental protection industry, and ensuring nuclear and radioactive safety.It called for implementing economic policies beneficial to environmental protection.The statement also ordered local governments at all levels to attach more importance to environmental protection, noting ecological conditions should be considered in evaluating the performance of local leaders.

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.

TEL AVIV, Jan. 25 (Xinhua) -- Israeli Prime Minister Benjamin Netanyahu on Tuesday praised the relations between Israel and China at a reception celebrating the 20th anniversary of the establishment of diplomatic ties between the two countries."We may be celebrating 20 years of relations, but our peoples are now celebrating a thousand years of friendship," Netanyahu said.He mentioned China's fair treatment towards the Jewish communities in the past, and the safe-haven given to them during the holocaust. "Like the Chinese people, the Jewish people have a long memory. We always remember our friends. We always remember people who extended a hand to us in our darkest days and we are grateful for China for that."Israli Prime Minister Benjamin Netanyahu (R) speaks at a reception celebrating the 20th anniversary of the establishment of diplomatic ties between China and Israel in Tel Aviv on Jan. 24, 2012.The prime minister said that the friendship between the two sides can further deepen. "I think we barely scratched the surface of Israeli-Chinese relations. I have no doubt that in the coming years we'll see a dramatic expansion of these ties," he said."We've talked about doubling the trade (between the two countries). Well, I'd like to see a doubling of a doubling of the trade. I think Israel and China together are a winning combination, " Netanyahu said.In addition to the prime minister, several other senior Israeli officials attended the reception, among them ministers, former ambassadors and envoys to China and key figures in the bilateral ties.Chinese ambassador Gao Yanping said that "Over the past 20 years our pragmatic cooperation has been booming. When we started our diplomatic relations in 1992, our two-way trade volume was only a little bit more than 50 million U.S. dollars. Now the trade volume we have in two days equals that of the whole year of 1992."She said that "The further development of China-Israel relations is not only beneficial to both countries and the two peoples, but also very much conductive to regional stability, world peace and global prosperity.""Facing the ongoing major transformation and adjustment in the region and in the world, the China-Israel relationship is now at a new historical point. We should continue to work together, grow together and succeed together in the years to come," Gao added.
