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.

NANJING, Dec. 8 (Xinhua) -- Chinese stargazers will have their best view of a total lunar eclipse in 10 years on Saturday if weather permits, the Zijinshan Astronomical Observatory under the Chinese Academy of Sciences (CAS) said Thursday.Wang Sichao, a research fellow with the observatory, said during the total eclipse, the full moon will not completely disappear from the Earth's shadow, but will take on a brilliant bronze color.He said the eclipse will be the best one seen in China since the last one occurred on Jan. 10, 2001."Theoretically, viewers can observe the eclipse from nearly everywhere in the country on Saturday," said the astronomer.He said the eclipse, the second this year, will last for 51 minutes. It will start at 8:45 p.m. and reach its climax at 10:06 p.m.Wang said Chinese viewers will have to wait until Oct. 8, 2014 to see the next total lunar eclipse.

NEW YORK, Oct. 14 (Xinhua) -- The iPhone 4S went on sale at Apple store on the Fifth Avenue of Manhattan in New York early Friday.An Apple store worker said people were waiting outside the store around 3 p.m. Thursday and underwent an overnight rain for an early purchase of the smart phone which started sale at 8 a.m. Friday.About 200 people were seen lining up outside the store and some of them said they would like to pay tribute to Steve Jobs, Apple's longtime CEO who died of pancreatic cancer at the age of 56 on Oct. 5."I'm a Steve's fan, iPhone 4S is the best of Steve's work. I am not going to buy iPhone 5,"Jim Bedford, who is in his 30s, said. "Maybe this is my last iPhone," he added.People left a Steve's picture, flowers and apples on the sidewalk to pay respect to Apple's co-founder. Some apples were seen inscribed such words as "Nice job" and "We will always remember you."Tom White, 50, said he had iPhone 1 and 3 and "now is the time to change a new one."The iPhone 4S is operated seven times faster than their predecessor and features an upgraded camera. Apple reported more than 1 million pre-orders for the iPhone 4S, breaking a mark set by last year's model. The phone also went on sale Friday in six other countries -- Britain,Germany,France,Australia, Canada and Japan.

BEIJING, Oct. 21 (Xinhuanet) -- A team of European researchers announced that they have found vast water vapor out of our solar system, according to a study in the U.S. journal Science Friday.Using Herschel Space Observatory, a European Space Agency satellite, the researchers observed that the vast water vapor enveloped a 175-light-year-away star and its surrounding dusk disk, which will eventually form a planet.The water vapor, which is "enough to fill thousand of Earth ocean", may rain down and seed the future oceans on the young planet, as it did on the Earth 4.5 billion years ago, the researchers suggested."Scientists have long suspected there were these reservoir of cold water hiding in the outer regions of planet disk, ... now the theory gets considerably stronger." said astronomer Michiel Hogerheijde of Leiden Observatory in the Netherlands.The finding not only explained where our Earth's ocean came from, but also indicated that there are likely to be many "ocean worlds" throughout the galaxies, he concluded.
