BEIJING, June 10 (Xinhua) -- The nation's drug watchdog on Friday publicized a draft national standard of sulfur dioxide residue in Chinese herbal medicine, which is open for public opinion until Sept. 9 this year.The maximum amount of sulfur dioxide residue is 400 mg in one kg of each of 11 specified kinds of herbal medicine, such as Chinese yams, Gastrodia elata and Codonopsis pilosola, according to the draft standard unveiled by the State Food and Drug Administration (SFDA).The standard provides a 150-mg-per-kg limit for all other kinds of herbal medicine.Fumigation with sulfur is used as a way of drying some herbal medicine by growers, and currently have no alternative that is both cheap and convenient.The SFDA said it doesn't favor the drying herbal medicine through fumigation with sulfur and urges research efforts to invent new alternatives.According to the World Health Organization, the tolerable maximum amount of sulfur dioxide that a human body can take in one day is 0.7 mg per kg, which means that an adult of 60 kg should not take in more than 42 mg of sulfur dioxide a day.Long-term exposure to high amounts of sulfur dioxide can cause damage to human body, especially the respiratory system, according to experts. 

CAIRO, July 4 (Xinhua) -- U.S. and Italian archeologists have discovered the oldest description about an Egyptian king (about 3, 200 BC) in Egypt's Aswan, Egyptian Antiquities Minister Zahi Hawass said on Monday.The engravings "traces back to when the Egyptian language firstly recorded in hieroglyphs and tells about a unique complete royal ceremony which was known in the ancient Egyptian era," said Hawass in a statement."The pharaoh appears to be wearing the Upper Egypt crown accompanied by (Horus apostles) at the royal court, " Hawass added.Horus is one of the oldest and most significant deities in the ancient Egyptian religion and was worshipped from at least the late Predynastic period through to Greco-Roman times."This discovery is considered a supplementary one at the site unearthed near in el-Hamdulab site in northern Aswan, archaeologists said.This is one of the latest discoveries in Egypt as the surrounding wall of Betah temple (1550 BC-1070 BC) and a gate traces back to Shabaka king era were unearthed on Saturday in Luxor.

BEIJING, June 11 (Xinhua) -- The Baidu Charitable Foundation (The Baidu Foundation) and The Bill & Melinda Gates Foundation (The Gates Foundation) founded a strategic charitable alliance here Saturday, in a bid to work for a healthy, smoke-free environment both in China and around the world.Li Yanhong, president of Baidu company, China's top online search engine operator, and Bill Gates, co-chair and trustee of the foundation under the names of the couple, attending the ceremony, both wore a shirt that said, "Say No to Forced Smoking."In his speech at the ceremony, Bill Gates said, "This will be a long-term, open-ended alliance. As a sponsor, Mr. Li and I would like to welcome more partners, and we expect to see more Chinese enterprises and all facets of society to focus on public health issues together."Li Yanhong also addressed the meeting, claiming, "Living healthy and green has become a common pursuit of mankind. We hope the alliance can bring together public efforts for this global cause, so that more people can benefit from our endeavor." ' The alliance's first action is to comply with the government ban on smoking in public places and refuse forced smoking, according to a press release from the foundations.Targeting "forced smokers," the alliance will carry out educational campaign through all channels of media to educate and promote self-awareness about the dangers of forced smoking. Moreover, it will also help existing smokers, especially those who are underage, by sharing scientific methods for quitting.Smoking is one of the world's eight primary causes of death, leading to lung disease, cancer, heart disease, low birth rate, fetal death, tuberculosis, high mortality and many other health issues. Smoking forces many families into poverty by causing both poor health and premature death.China ranks first in tobacco consumption and production in the world. China has 300 million smokers, and one in every three cigarettes smoked in the world is smoked in China. More than half of Chinese smokers are male; and more than 1 million people die from smoking related diseases each year.In addition, China has 740 million "forced smokers," whose health also suffers. The World Health Organization (WHO) notes that there is no safe level of second-hand smoke.This year, China published its 12th Five-Year Plan (2011-2015) that clearly stipulates for "implementing a full-scale ban on smoking in public facilities." This is the first time that tobacco control has been included as part of China's five-year plan for national economic and social development."Rules for Implementation of Public Facilities Health Management Regulations," effective since May 1st, also specifies to "ban smoking at all public indoor facilities," providing legal basis for non-smokers to protect their rights of health and to refuse "involuntary smoking."Aside from tobacco control, the strategic alliance co-founded by the foundations will also collaborate on a series of projects, such as AIDS prevention and control, in a joint effort to promote health for mankind.Founded in 2000, the Gates Foundation currently carries out charity projects in over 100 countries. Since establishing the Beijing Representative Office in 2007, the Gates Foundation has supported a range of health and development projects in China, including the advocacy of smoke-free environment, AIDS and tuberculosis prevention and control, and agricultural development and research projects.Launched in 2010, the Baidu Foundation is committed to use information technology for support of youth and disadvantaged groups, focus on the environment and promote social harmony.Ever since Baidu was founded, Li has actively pushed for tobacco control within the enterprise and the industry. He is the only Chinese member of the United Nation AIDS Prevention Senior Committee and also board member of the HuaXia Charity Foundation.

BEIJING, Aug. 21 (Xinhuanet) -- The 7th Beijing-Tokyo Forum opened in Beijing on Sunday.This year’s forum, the Future of Asia and China-Japan Cooperation in Economic Reshaping, expects about 600 leaders from the political, business, academic and media fields to take part in a two-day discussion focusing on China-Japan cooperation.Wang Chen, minister of the State Council Information Office, delivers a speech at the reception for Beijing-Tokyo Forum on Saturday night in Beijing.Wang Chen, minister of the State Council Information Office, said at the reception on Saturday for the forum that China pursues an open development that is not exclusive to the rest of the world, but instead ensures cooperation and win-win with other countries."China and Japan’s economy are highly reliant on each other, and they are so close that they cannot get separated from each other,” Wang said.

WASHINGTON, Sept. 15 (Xinhua) -- A team of researchers has discovered a planet that orbits around a pair of stars, the U.S. space agency NASA announced Thursday.This is the first instance of astronomers finding direct evidence of a so-called circumbinary planet. A few other planets have been suspected of orbiting around both members of a dual-star system, but the transits of the circumbinary planet have never been detected previously.The team, led by Laurance Doyle of the SETI Institute in California, used photometric data from the NASA Kepler space telescope, which monitors the brightness of 155,000 stars.NASA's Kepler mission has discovered a world where two suns set over the horizon instead of just one. The planet, called Kepler-16b, is the most "Tatooine-like" planet yet found in our galaxy. Tatooine is the name of Luke Skywalker's home world in the science fiction movie Star Wars. In this case, the planet it not thought to be habitable. It is a cold world, with a gaseous surface, but like Tatooine, it circles two stars.They found the binary star system by detecting a system where the stars eclipsed each other from the perspective of the Kepler spacecraft. These stars have two eclipses: A primary eclipse when the larger star is partially blocked by the smaller star and a secondary eclipse where the smaller star is fully blocked by the larger star.But the researchers also noticed other times when the brightness of the two stars dropped, even when they were not in an eclipse position. This pattern suggested that there was likely a third object involved. The fact that these so-called tertiary and quaternary eclipses recurred after varying intervals of time, and were of different depths, indicated that the stars were in different positions in their orbit at each instance. This result showed that the tertiary and quaternary eclipses were being caused by something circling both stars, and not an object circling one or the other star.Measurements of the variations in the timing of all four types of eclipses, resulting from the mutual gravitational interactions of the two stars and the third body, demonstrated that the third object was, indeed, a planet. Their work indicates that the planet is less massive than Jupiter, possibly comparable in mass to Saturn, and that the larger of the two binary stars is smaller than our Sun.Their findings will be published Friday in Science."This discovery confirms a new class of planetary systems that could harbor life," Kepler principal investigator William Borucki said in a statement. "Given that most stars in our galaxy are part of a binary system, this means the opportunities for life are much broader than if planets form only around single stars. This milestone discovery confirms a theory that scientists have had for decades but could not prove until now."
