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."

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.

SAN FRANCISCO, Sept. 12 (Xinhua) -- Amazon.com Inc. is talking with book publishers to launch a rental subscription service for digital books, U.S. media reported on Monday.Several publishing executives said they aren't enthusiastic about the idea because it could lower the value of books and it could also strain their relationships with other retailers that sell their books, The Wall Street Journal quotes people familiar with the matter in a report.The Seattle-based company is considering a digital book library featuring old titles, which would be available to Amazon Prime subscribers, who currently pay 79 U.S. dollars a year for access to digital library of movies and TV shows and unlimited two-day shipping, said the report.Amazon would offer book publishers a substantial fee and could limit the amount of books that Amazon Prime customers could read for free every month, the report cited some sources as saying.The online retailing giant makes the popular electronic reader Kindle and is also reported to launch a color touchscreen tablet before October to compete with Apple's iPad and other devices in the increasingly crowded tablet computer market.The proposal is another sign that retailers are looking for more ways to deliver content digitally as customers increasingly read book and watch TV on personal computers, tablets and other electronic devices, said The Wall Street Journal report.

RIO DE JANEIRO, Sept. 26 (Xinhua) -- Rio de Janeiro has the highest level of air pollution in Brazil, and is more polluted than many other world metropolis like New York, London and Paris, a World Health Organization (WHO) study said Monday.According to the study, which was carried out in 91 countries and regions, the air in Rio's metropolitan area contains 64 micrograms of fine particulate matter per cubic meter, over three times the upper limit set by the WHO, which is 20 micrograms per cubic meter.Despite being larger, having a bigger population and more vehicles, Sao Paulo's metropolitan area has less air pollution, with 38 micrograms of fine particulate matter per cubic meter.According to the WHO, "the largest contributors to urban outdoor air pollution include motor transport, small-scale manufacturers and other industries, burning of biomass and coal for cooking and heating, as well as coal-fired power plants." The organization said that residential wood and coal burning for heating also help increase air pollution, especially in rural areas in the cold months.The WHO expressed concern over air pollution levels in several cities, as some two million people worldwide die annually from conditions resulting from air pollution."Air pollution is a major environmental health issue, and it is vital that we increase efforts to reduce the health burden it creates," said Dr. Maria Neira, WHO's director for Public Health and Environment.According to the study, Ahwaz, Iran, has the most polluted air in the world, with 372 micrograms of fine particulate matter per cubic meter.

SHENZHEN, June 4 (Xinhua) -- Chinese scientists who have fully sequenced the genome of the new E. Coli spreading through Europe said Saturday they found genes in the bacteria that gave it resistance to eight classes of antibiotics.Researchers with the Beijing Genomics Institute, the world's largest DNA sequencing center, have found genes in the newly identified 0104 strain of E. Coli bacteria that made it resistant to major classes of antibiotics including sulfonamide, cephalothin, penicillin and streptomycin.This helped explain why doctors in Europe had difficulties in fighting the bug that has killed 18 people and sickened nearly 2,000, BGI's major research arm in Shenzhen said on its website Saturday.This would help doctors choose right medicines for the treatment, it said.The researchers are developing a diagnostic kit which will be used to detect the bacteria and prevent the epidemic from spreading further.The Chinese researchers obtained DNA samples of the bacteria from collaborating scientists in Germany and fully sequenced its genome in three days this week.They announced on Thursday the E. Coli spreading through Europe was "a new strain of bacteria that is highly infectious and toxic".The 0104 strain of E. Coli was not previously involved in any E. Coli outbreaks. However, it has 93 percent sequence similarity with the EAEC 55989 E. Coli strain which was isolated in the Central African Republic and known to cause seriously diarrhea, BGI said.The source of the outbreak is unknown, but scientists say it is highly likely to have originated in contaminated vegetables or salad in Germany.
