BERLIN, Jan. 17 (Xinhua) -- Researchers in Germany have found a cheap and easy way to synthesize anti-malaria drug in large quantities from waste materials, said the Max Planck Society on Tuesday.Currently there are nearly one million people die worldwide each year due to lack of effective drugs, as sweet wormwood, from which artemisinin, the effective essence to fight malaria can be extracted, only grows in China, Vietnam and a few other countries.However, researchers in Germany have now developed a simple process for the synthesis of artemisinin in laboratory, using artemisinic acid, a substance contained in the by-product, or waste materials of the isolation of artemisinin from sweet wormwoods, as row materials of synthesizing artemisinin."The production of the drug is therefore no longer dependent on obtaining the active ingredient from plants," said Peter Seeberger, director at the Max Planck Institute of Colloids and Interfaces in Potsdam and professor at Free University of Berlin.The artemisinic acid in the waste material boasts a volume 10 times greater than the active ingredient itself, said Seeberger, and they could be turned into artemisinin in four and a half minutes in a so-called continuous-flow reactor.Seeberger estimated that 800 of the reactors would be enough to cover the global requirement for artemisinin, and the whole innovative synthesis process could be ready for technical use in three to six months.Malaria is a disease caused by parasites that are transmitted to people through the bites of infected mosquitoes. In 2010, malaria caused an estimated 655,000 deaths, mostly among African children.
JIUQUAN, Oct. 26 (Xinhua) -- China will launch the spacecraft Shenzhou-8 in early November at the Jiuquan Satellite Launch Center in northwest deseart area.The unmanned spacecraft is expected to perform China's first space docking with Tiangong-1, or Heavenly Palace-1, a space lab module that was launched in September from the same launch center.The spacecraft and its carrier rocket, an upgraded Long March-2F, were transferred on Wednesday morning on a 20-meter-wide railway to the launch pad.The launch pad is 1,500 meters away from the assembling and testing center. It took nearly two hours to complete the transfer.Technicians completed testing on the assembling of Shenzhou-8 and the rocket after they were delivered to the launch center at the end of August, said Lu Jinrong, the launch center's chief engineer.In the next few days, the launch center will continue testing the spacecraft and the rocket, and inject propellent before the final launch in early November, Lu said.The assembling, testing and transferring of the spacecraft and rocket were all conducted while they were vertical.Shenzhou-8 is capable of docking with the spacecraft Tiangong-1 in both manual and automatic modes.The Tiangong-1 space lab module is functioning smoothly in the orbit, and all equipment and experiments are going well, according to Lu. The module is ready for the docking task, Lu said.
BEIJING, Nov. 24 (Xinhua) -- In response to public suspicion stoked by recent dumpling contamination scandals, China's Ministry of Health on Thursday said the new food safety standard for flash-frozen dumplings did not show signs of leniency.The Ministry introduced the new food safety standard on flash-frozen dough or rice products on Thursday.The Ministry has been accused of loosening scrutiny over a disease-generating bacteria in such foods, staphylococcus aureus, or golden staph, which can cause various diseases, including pneumonia and sepsis, and is sometimes life-threatening.The controversy became particularly relevant after several major brands of frozen dumplings have been successively recalled in recent months.In October, a Henan-based company, Zhengzhou Sinian Food Co., Ltd, confirmed the contamination of golden staph in its flash-frozen seafood- and pork-stuffed dumplings.Frozen dumplings made by Hong Kong-based manufacturer Wanchai Ferry were found to contain golden staph in November, and some of its products have been pulled from shelves.The previous standard provided that no golden staph should be tested in such food, while the new one gives a quantitative restriction that the volume of the bacteria should be no more than ten to the fourth degree.Liu Xiumei, a food safety expert with the Chinese Center for Disease Control and Prevention, said at the press conference held by the health ministry that such bacteria becomes inactivate after the food is boiled for a few seconds, and it takes a volume of ten to the fifth degree to generate toxicity.The previous standard could only serve as a general provision due to the lack of quantitative microbiological testing back when it was introduced, Liu said, stressing that the new standard is not a sign that the Ministry has gone soft on bacterial contamination of relevant foods.The new standard will come into effect starting Dec. 21, 2011.
BEIJING, Jan. 6 (Xinhua) -- Beijing will offer residents 20,000 rental bikes this year to ease the city's notorious traffic jams, according to authorities with the Beijing Municipal Commission of Development and Reform.Five hundred rental kiosks will be set up around the city to offer residents over 20,000 rental bikes, the commission said.Beijing has also proposed creating new bike lanes in some areas, including main streets, historical and cultural conservation areas and some major business districts, from 2011 to 2015, according to the commission.The capital city currently has about 5 million vehicles on its roads, leading to serious traffic congestion that frustrates the city's residents on a daily basis."A lack of bike lanes is the reason why I refuse to ride a bike. Bikes and vehicles are using the same lanes, and that frightens me and makes me feel unsafe," said Beijing resident Song Tao.People often park cars on the city's existing bike lanes, pushing cyclists onto the vehicles' lanes, said Song.To ease traffic congestion, Beijing has made various efforts to encourage people to opt for modes of public transportation.On Dec. 31, Beijing opened three new subway lines, bringing the number of subway lines in Beijing to 15, with a total length of 372 kilometers, said Beijing Metro Spokesman Jia Peng.Beijing will open four more subway lines in 2012, according to information released at a rail transit construction mobilization conference.Amid other measures to ease traffic in 2011, city authorities decided to allow only 240,000 vehicles to be registered annually, slashing the new car registrations by two-thirds from the 2010 level.Meanwhile, vehicles are banned from roads one day each week according to license plate numbers.
BEIJING, Nov. 26 (Xinhua) -- In response to the government's call to build a greener economy, China's transport authorities have taken a slew of measures to promote energy saving and emission reductions in the sector.Under the sector's funding policy unveiled earlier this year, 122 emission-cutting projects in the industry have received financial support totalling 250 million yuan (39.3 million U.S. dollars). Encouraged by the special funds, another 8.06 billion yuan in investment went to the projects, according to He Jianzhong, spokesman for the Ministry of Transport (MOT).The projects were estimated to be able to save 315,000 metric tons of coal equivalent, replace 224,000 metric tons of fuel oil and reduce carbon dioxide emission by 1.14 million metric tons, He said.Meanwhile, the MOT has launched nationwide programs to promote low-carbon traffic. It has carried out 80 pilot projects on emission control and designated 10 cities as pilot areas to study and promote green transport system, including Tianjin, Shenzhen, Xiamen, Guiyang, Baoding and Wuhan.He said the ministry will continue to intensify efforts to regulate emissions in the sector to meet the industry's control target during the 12th Five-Year Plan period (2011-2015).In efforts to build a more environmental-friendly society, the government pledged that it will reduce the intensity of carbon dioxide emissions per unit of economic output in 2020 by 40 to 45 percent compared with the level of 2005.
