BERLIN, June 10 (Xinhua) -- The German state of North Rhine-Westphalia said Friday it detected for the first time the deadly E.coli strain o104 on bean sprouts, after they were named the source of the outbreak by Germany's national disease control centre. "According to our knowledge, the bean sprouts are coming from the recent suspicious farm in Bienenbuettel in the state of Lower Saxony," said Johannes Remmel, consumer protection minister.The sprouts were found in an opened package which had been left in a dustbin of a family, living near the city of Bonn. Two of the family members had eaten the sprouts and contracted the E. coli infection in mid-May, he said.A notice warning consumers not to eat raw bean sprouts is seen at a market in Berlin, capital of Germany, June 10, 2011. The German authority said on Friday bean sprouts were probably the source of the E. coli outbreak, which has killed 30 people and infected about 3,000 around the world. Reinhard Burger, president of the Robert Koch Institute (RKI), Germany's national disease control center said the Robert Koch Institute was lifting its warning against eating cucumbers, tomatoes and lettuce but keeping the warning in place for the sprouts."The discovery confirms our current warning against the consumption of bean sprouts. It is therefore becoming increasingly more likely that bean sprouts are the source of the E.coli infections," Remmel said.The news came after Reinhard Burger, President of the Robert Koch Institute (RKI), said in the morning bean sprouts were the source for the outbreak based on a epidemiological investigation."People who ate (bean) sprouts were found nine times more likely to have bloody diarrhoea or other signs of E. coli infection than those who did not," he saidHowever, no sample tests had found the o104 strain on bean sprouts when he announced that conclusion. Laboratory tests have shown Germany made mistakes in identifying the outbreak source on two previous occasions.At the same time, RKI lifted the warning against cucumbers, tomatoes and lettuce."Enjoy lettuce, cucumbers and tomatoes. They are healthy for you," said Andreas Hensel, president of the German Federal Risk Assessment Institute (BFR), which is a co-leader in the action against E. coli.In the city of Hamburg, an epicentre for the disease, farmers protested in the city centre by offering tons of lettuce and cucumbers for free to anyone who wanted them when the news was announced. Suddenly, pedestrians turned from reluctant to eager takers, reported local news agency DPA.

WASHINGTON, Aug. 4 (Xinhua) -- U.S. scientists have found two gene mutations occurring in oligodendrogliomas, the second-most common form of brain cancer, according to a study to be published Friday in journal Science.For years scientists have been looking for the primary cancer genes involved in oligodendrogliomas evolvement. Scientists know the two chromosomes held the probable mutations, but the particular gene information remains unclear.Now scientists at Duke University Medical Center and Johns Hopkins University have discovered the most likely genetic mutations that researchers have been hunting for on chromosomes 1 and 19.The genes they identified, CIC or FUBP1, are tumor suppressor genes. The cancer-related pathways that involve these genes could become targets for future treatments, said Hai Yan, a Duke associate professor of pathology and co-corresponding author of the study.The researchers found CIC on chromosome 19 and FUBP1 on chromosome 1 based on an initial study of seven oligodendrogliomas. They found six mutations and two mutations, respectively, in the seven tumors. Further study of 27 more of these tumors showed that there were 12 and three mutations of CIC and FUBP1, respectively. The two genes were rarely mutated in other types of cancers, indicating that they are oligodendroglioma-specific genes.These genes were difficult to find until the technology improved, said Yan."The team used whole genome sequencing technology so that no genes would be excluded, and we found to our surprise that one gene, on chromosome 19, was mutated in six out of the seven initial tumor specimens we sequenced," Yan said. "A mutation frequency of 85 percent is very high."The finding of two additional new genes involved in oligodendrogliomas increases the chances for an effective combination drug therapy for the tumor, Yan said. He envisions a combination cocktail of drugs similar to the combination-drug treatments taken by HIV patients that would target different pathways involved in cancer, and assist both in reducing the chance of relapsing and increasing odds of success.

PARIS, June 14 (Xinhua) -- Solar Impulse, a Swiss solar-powered aircraft, finally arrived in Paris on Tuesday after three days' delay, ready for a debut at the biennial International Paris Air Show.The 1.6-ton solar-powered plane was expected to land in Paris on Saturday but technical problems and bad weather forced it to turn back to Brussels.The plane took its first international flight from Switzerland to Brussels on May 13 and then marked its second international flight to Paris. It has 12,000 solar cells mounted on the wings, which provide momentum for its four electric motors.Solar Impulse is the first aeroplane designed to fly day and night without requiring fuel and without producing carbon emission. The 64-meter-wingspan (as wide as an Airbus A340) can fly at extremely slow speed and has a weight equivalent to that of an average family car.Regarded as a "special guest" in the show, Solar Impulse made a historic 26-hour day and night flight without fuel in July 2010.During the Paris air show from 20 to 26 June, visitors can enjoy a close look at the innovative plane on ground every day and if weather condition permits, flying displays will take place.According to Paris Air Show organizers, 59 of the top 100 companies in the air industry worldwide will be present. More than 1,800 small and medium-sized companies will be exhibiting their products during the one-week show. Enditem

CANBERRA, Sept. 9 (Xinhua) -- Managing other people at work triggers structural changes in the brain, protecting its memory and learning center well into old age, Australia's study revealed on Friday.Australia's University of New South Wales (UNSW) researchers have, for the first time, identified a clear link between managerial experience throughout a person's working life, and the integrity and larger size of an individual's hippocampus (the area of the brain responsible for learning and memory) at the age of 80. "We found a clear relationship between the number of employees a person may have supervised or been responsible for and the size of the hippocampus," Dr Michael Valenzuela, Leader of Regenerative Neuroscience in UNSW's School of Psychiatry, said in a statement released on Friday."This could be linked to the unique mental demands of managing people, which requires continuous problem solving, short term memory and a lot of emotional intelligence, such as the ability to put yourself in another person's shoes. Over time this could translate into the structural brain changes we observed."The findings confirmed that staying mentally active promotes brain health, potentially warding off neurodegenerative diseases such as Alzheimer's.Using MRI imagery in a cohort of 75-92 year-olds, researchers found larger hippocampal volumes in those with managerial experience compared to those without. The effect was also seen in women who had taken on managerial roles in nursing or teaching, for example.The study was presented at this week's Brain Sciences UNSW symposium Brain Plasticity The Adaptable Brain, held in Australia.

BEIJING, Aug. 12 (Xinhuanet) -- A Connecticut woman who was savagely attacked by a pet chimpanzee and had her face deformed in 2009 was shown on TV with a new face Thursday.TV pictures revealed Charla Nash’s new nose, lips and eyelid, which were transplanted in May by doctors at the Brigham and Women’s Hospital in Boston.Nash said to the viewers that she can move her mouth, smile and smell. Her daughter Brianna added that her mother can even talk and eat better now.Dr. Bohdan Pomanhac led a 30-member surgical team to complete the face transplant in 20 hours. The team also transplanted two hands but these were later removed due to blood flow problem when Nash suffered pneumonia.Nash’s friend Sandra Herold owned a 15-year-old chimpanzee named Travis that attacked without any provocation when Nash was visiting Herold.Travis simply went berserk and could not be stopped even after Herold stabbed it with a kitchen knife. It would only let go of Nash after the police arrived and shot it dead.
