BEIJING, Sept. 26 (Xinhua) -- Nobel laureates on Monday cast doubt on a European experiment that purportedly demonstrated the ability of neutrinos to move faster than the speed of light.They made the remarks in Beijing prior to a forum for Nobel laureates."I'm willing to bet money that it's not correct," said Professor George Smoot III, winner of the 2006 Nobel Prize in Physics and a professor at University of California, Berkeley, referring to an experiment result claiming that particles apparently travel faster than light.The experiment reported an anomaly in the flight time of neutrinos, or electrically neutral subatomic particles, from the European Center for Nuclear Research (CERN) in Switzerland to a laboratory located 730 kilometers away in Italy.Particles were clocked transmitting at a speed of 300,006 kilometers per second, about 60 nanoseconds faster than the speed of light.Smoot said that the claims "did not make sense" and should be verified by other scientists first."There are many distortions in physics. You have to have a very high standard to see if something is truly correct," he said.The unverified findings were published on Sept. 22 in the scientific journal Nature. European researchers working in a team called OPERA (Oscillation Project with Emulsion-Racking Apparatus) projected masses of neutrinos from CERN and then collected the particles using a massive detector in Gran Sasso, south of Rome.Other scientists, as well as the OPERA team themselves, have voiced doubts regarding the experiment's results.The findings, CERN claims, could pose far-reaching potential consequences once verified.If correct, the results would bring Einstein's theory of special relativity into question. Under this theory, a physical object cannot travel faster than the speed of light in a vacuum."If really it is right, we have to rethink everything we know," said Chris Llewellyn Smith, former director of CERN.Smith claimed the unprecedented discovery was too exceptional to find proof."If somebody makes a very exceptional claim, then very exceptional proof would need to come from another experiment, saying the same thing. But we don't have the other thing," Smith said.Carlos Rubbia, a Nobel Laureate who won the prize for physics in 1984, is in charge of a team of more than 100 scientists at CERN."What it is pretending to find, in my view, is unbelievably surprising," Rubbia said."Frankly, I have the feeling that this is still a very experimental consideration," Rubbia said.He also believes that revealing the findings to the public was a mistake as it remained an experimental process and no conclusion could be drawn without the results of another experiment.Despite the possibility of verification, Einstein's special theory of relativity will remain valid."I will be very, very surprised that, at last, Einstein will not be the winner," Rubbia said.To achieve a breakthrough, Rubbia has urged for more joint cooperation on verifying the test results. International cooperation on this issue "is a must.""It requires coordination from all nations," said Rubbia.The 2011 Nobel Laureates Beijing Forum will be held from Sept. 28 to 30 under a theme of "innovation and development."

BUJUMBURA, May 31(Xinhua) -- As the World No Tobacco Day is celebrated on Tuesday, many Burundians feel happy that they have given up smoking thanks to herbal drugs.Evariste Ndikumwami, 55, residing in the Burundian capital Bujumbura, said he had been smoking for 30 years, but gave up smoking in January after taking herbal drugs prescribed by an abbot."I had been smoking since my teenage and I gave up smoking in January (this year) after I took herbal drugs that I got from a Roman Catholic priest from Uganda working at Rugari parish in the province of Muyinga, some 210 km northeast of the Burundian capital Bujumbura," Ndikumwami told Xinhua.Ndikumwami said he used to smoke a pack of 20 cigarettes per day, adding that he had found it hard to give up smoking.He said, "I took the herbal drugs for 15 days. The abbot prescribed me two herbal drugs -- one to be smoked for five days at daytime when I desire to smoke and another one to be applied around the nostrils at night."After the medication period, he never felt the desire for smoking cigarettes, he said."When my friends realized I was no longer smoking, they asked me which drugs I took to give up smoking. I directed them to the abbot who had healed me and they also got cured and stopped smoking," Ndikumwami said.

WASHINGTON, July 5 (Xinhua) -- Adhering to a healthy lifestyle, including not smoking, exercising regularly, having a low body weight and eating a healthy diet, appears to lower the risk of sudden cardiac death (SCD) in women, according to a study to be published Wednesday in the Journal of the American Medical Association."Sudden cardiac death (defined as death occurring within one hour after symptom onset without evidence of circulatory collapse) accounts for more than half of all cardiac deaths, with an incidence of approximately 250,000 to 310,000 cases annually in the United States," the authors write as background information in the study.Using data collected as part of the Nurses' Health Study, Stephanie Chiuve, of Brigham and Women's Hospital and Harvard Medical School, and colleagues examined the association between a healthy lifestyle and risk of SCD.A total of 81,722 women who participated in the Nurses' Health Study from June 1984 to June 2010 were included in the new study, and lifestyle factors were assessed via questionnaires every two to four years. A low-risk lifestyle was defined as not smoking, having a body mass index (BMI) of less than 25, exercise duration of 30 minutes/day or longer, and consuming a diet closely related to a Mediterranean-style diet (emphasizes high intake of vegetables, fruits, nuts, legumes, whole grains and fish, with moderate alcohol intake).During the 26 years of follow-up, there were 321 cases of SCD among women (average age 72 years at the time of the SCD event) in the study. All four low-risk factors were significantly and independently associated with a lower risk of SCD. Not smoking, exercising and eating a healthy diet each were inversely associated with risk of SCD. BMI also was associated with the risk of SCD, with women having a BMI between 21 and 24.9 at lowest risk.Women at low risk for all four lifestyle factors had a 92 percent lower risk of SCD when compared with women at low risk for none of the four lifestyle factors."In this cohort of female nurses, adherence to an overall healthy lifestyle was associated with a lower risk of SCD and may be an effective strategy for the prevention of SCD," the authors write.

KATSINA, Nigeria May 31 (Xinhua) -- At least 10 secondary school teachers are reported to have died of food poisoning, and several others hospitalized in northern Nigeria's Katsina State, the News Agency of Nigeria reported on Tuesday.The incident occurred at the weekend at a workshop organiZed by the state Ministry of Education for some 650 teachers at Government Day Secondary School (GDSS), Kofar Yan'daka, Katsina.The report said soon after taking their lunch, supplied by a popular corporate caterer on the fateful day, some of the teachers were vomiting and afflicted by diarrhoea, as a result of which they were rushed to the Federal Medical Center, Katsina and the Police Clinic for medication.Ten of the affected teachers were said to have died as a result of the infection.State police spokesperson Abubakar Ibrahim confirmed the incident to reporters.He said only one teacher died, while 19 others were hospitalized.He said 12 of the affected teachers had already been discharged from the hospitals, while seven others were still on admission at the Federal Medical Center and Katsina Police Clinic.He said the police had already collected sample of the food supplied by the caterer for clinical analysis.

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.
