BEIJING, July 6 (Xinhua) -- The Ministry of Health has issued a national standard on compound food additives to better regulate the production and use of such additives and ensure food safety.Compound food additives, which are designed to improve food quality or assist in food processing, should be used sparingly in food products, according to the standard the ministry issued Tuesday.Titled the General Rule on Compound Food Additives, the standard stipulates that each of the ingredients used for making compound food additives, which are a mix of two or more single food additives, should meet national standards concerning food safety.No chemical reaction should occur and no new compounds should be generated during the production process of compound food additives, according to the standard.Compound food additives producers should clarify limits of the amounts of harmful substances, such as lead and arsenic, in their products and take measures to control the levels of harmful substances, according to the standard, which will come into effect on Sept. 5 this year.

BEIJING, Aug. 25 (Xinhua) -- China pledged on Thursday to make more efforts to aid people living in the drought-stricken Horn of Africa in collaboration with the International Committee for the Red Cross (ICRC)."We noticed that the ICRC launched an appeal regarding the situation in the Horn of Africa. The Red Cross Society of China (RCSC) has decided to donate 4 million yuan (about 623,000 U.S. dollars) to the ICRC for its humanitarian aid in the region," said Hua Jianmin, president of the RCSC, while meeting with visiting ICRC President Jakob Kellenberger in Beijing on Thursday.Earlier this month, the RCSC donated 8 million yuan (1.25 million dollars) to famine-plagued countries in the Horn of Africa to be used for emergency humanitarian aid.A donation of 2 million yuan was sent to Kenya through the country's Red Cross organization, while another 2 million went to Ethiopia. The other 4 million yuan was donated to other countries in the region.The Chinese government has decided to provide a total of 90 million yuan (14 million dollars) in emergency food assistance to countries in the Horn of Africa."The Red Cross Society of China is willing to work together with the International Committee for the Red Cross to meet the needs of those who have been affected (by the droughts)," Hua said.Some 12.4 million people in Kenya, Ethiopia, Somalia and other countries in the region are in dire need of food due to a serious drought, the worst to hit the region since the 1980s.

BERLIN, June 14 (Xinhua) -- A two-year-old boy became the first child to be killed by the deadly E. coli in Germany on Tuesday, officials said.To date, the terrifying EHEC infection has claimed 36 lives in Germany and one in Sweden.The child, from the northern town of Celle, died in hospital in Hanover of kidney failure and abnormal breakdown of red blood cells, two extreme symptoms of the infection with enterohaemorrhagic E. coli (EHEC), authorities in the state of Lower Saxony said.The boy became the youngest known fatal victim since the outbreak of E. coli in May. His father and 10-year-old brother were also infected with the deadly bacteria, but are recovering, doctors told a local newspaper.The Robert Koch Institute, Germany's national disease prevention and control agency, said on Tuesday that a total of 3, 235 cases had been reported in the country. Among them, 782 people are suffering from haemolytic uraemic syndrome (HUS), a life- threatening illness arising from E. coli, which would destroy human kidney and nervous system.The institute added that the number of new infections is declining sharply in recent days, with only seven reported on Tuesday.German authorities announced on Friday that bean sprouts from a farm in northern Germany were one source of the outbreak, and dropped the previous warning against eating raw cucumbers, tomatoes and lettuce. However, the food panic has caused losses worth hundreds of millions of dollars for European farmers.

WASHINGTON, June 15 (Xinhua) -- Using the deepest X-ray image ever taken, astronomers found the first direct evidence that massive black holes were common in the early universe, the U.S. National Aeronautics and Space Administration (NASA) said Wednesday in a statement.The discovery from NASA's Chandra X-ray Observatory shows that very young black holes grew more aggressively than previously thought, in tandem with the growth of their host galaxies.By pointing Chandra at a patch of sky for more than six weeks, astronomers obtained what is known as the Chandra Deep Field South (CDFS). When combined with very deep optical and infrared images from NASA's Hubble Space Telescope, the new Chandra data allowed astronomers to search for black holes in 200 distant galaxies, from when the universe was between about 800 million to 950 million years old."Until now, we had no idea what the black holes in these early galaxies were doing, or if they even existed," said Ezequiel Treister of the University of Hawaii, lead author of the study to appear Thursday in journal Nature. "Now we know they are there, and they are growing like gangbusters."The super-sized growth means that the black holes in the CDFS are less extreme versions of quasars -- very luminous, rare objects powered by material falling onto supermassive black holes. However, the sources in the CDFS are about a hundred times fainter and the black holes are about a thousand times less massive than the ones in quasars.The observations found that between 30 and 100 percent of the distant galaxies contain growing supermassive black holes. Extrapolating these results from the small observed field to the full sky, there are at least 30 million supermassive black holes in the early universe. This is a factor of 10,000 larger than the estimated number of quasars in the early universe."It appears we've found a whole new population of baby black holes," said co-author Kevin Schawinski of Yale University. "We think these babies will grow by a factor of about a hundred or a thousand, eventually becoming like the giant black holes we see today almost 13 billion years later."

SAN FRANCISCO, June 14 (Xinhua) -- Google on Tuesday introduced several new features of its search services on desktops and smartphones, which the Internet search giant said could help users get to their search results faster.SEARCH BY VOICE, IMAGESpeaking at Google's Inside Search event in San Francisco, Mike Cohen, head of the company's speech technology efforts, said its voice search is now available in 27 languages and dialects, an estimated coverage of around 5 billion people or two-thirds of world population.Voice search has already been available in Google's mobile search application from 2008. Adding the feature to desktops is part of Google's strategy to bring mobile innovations to its desktop search.The voice search on desktop performs similarly to voice search on smartphones -- users can click the microphone button and speak the query. It is only available via Google's Chrome browser for now.Cohen noted that the volume of Google mobile speech inputs has increased by six times in the last year.Also at the event, Google introduced search-by-image, which enables users to drag-and-drop, copy-and-paste image URL, or upload the image from the desktop into the search box. They can also use a Chrome or FireFox software extension to add images to the search.Google said the search-by-image feature will be available in most countries and regions over the next few days to Chrome users, noting that it will not collect and store any images that users use.
