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.

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."

MOSCOW, Sept. 21 (Xinhua) -- A Russian Proton-M carrier rocket carrying a military spacecraft blasted off early Wednesday from the Baikonur space center in Kazakhstan, the first launch since a series setbacks of Russian rocket launch in August.Colonel Alexei Zolotukhin, spokesman of the Russian Space Forces, told reporters that the successful launch took place at 02:47 Moscow time (2247 GMT Tuesday) as scheduled."The spacecraft is scheduled to separate from the Briz-M booster at 11:48 Moscow time (0748 GMT)," Zolotukhin said.The military spacecraft delivered by the Proton-M belongs to the Russian Defense Ministry.Local reports said the Wednesday launch was originally planned for Aug. 31, but was postponed due to an investigation into a failed launch of a Proton-M rocket carrying an Express-AM4 satellite on Aug. 18.After the failure, Russia decided to suspend launches of rocket Proton-M pending the outcome of a probe into the accident.On Aug. 24, a Progress M-12M cargo ship also failed to reach the orbit due to a rocket malfunction. Russia delayed the launch of next manned spaceship to the International Space Station (ISS).

SAN FRANCISCO, Aug. 17 (Xinhua) -- Microsoft's cloud-based software Microsoft Office 365 on Wednesday experienced its first major outage since its introduction in late June."At approximately 11:30 a.m. PDT, Microsoft became aware of a networking issue affecting customers of some Microsoft services hosted out of one of our North American data centers," said Steven Gerri, general manager for Microsoft Global Foundation Services, in a statement"We apologize for the inconvenience that Office 365 outage has caused today. We are working on resolving the issue," the software giant said via Twitter.Outages were reported in Chicago, Denver and New York City among other locations. According to tweets from affected users, they were unable to access their email and managers were unable to manage accounts.The outage lasted approximately five hours and services have been restored for the moment.According to Microsoft service-level agreement, Microsoft guarantees a 99.9 percent level of uptime. If it fails to reach 99.9 percent uptime, users are eligible for 25 percent service credit.As more industry giants try to entice users to move to the "cloud," a term refers to the management and provision of applications and data over the Internet, the downtime again reminds cloud computing users that they must prepare to deal with outages and rethink their dependency on the service, analysts said.Amazon has suffered two major cloud outages earlier this month and back in April, impacting some of its high-profile users like movie streaming service Netflix and location-based social networking Foursquare.Analysts recommend cloud users to store data with multiple service providers to minimize the risk and limit their dependency on cloud services for business-critical processes.Available in 40 countries and regions since June 28, Office 365, which Microsoft CEO Steve Ballmer said is "where Microsoft office meets the cloud," combines Microsoft Office, SharePoint Online, Exchange Online and Lync Online into a single cloud-based package for business users.

WASHINGTON, June 7 (Xinhua) -- Advanced hepatitis C patients with chronic liver disease may benefit from drinking coffee during treatment, according to a new study published Tuesday in Gastroenterology, the official journal of the American Gastroenterological Association Institute.The study shows that patients who received peginterferon plus ribavirin treatment and who drank three or more cups of coffee per day were two times more likely to respond to treatment than non- drinkers.Among non-drinkers, 46 percent had an early virologic response; 26 percent had no detectable serum hepatitis C virus (HCV) ribonucleic acid at week 20; 22 percent had no detectable serum at week 48; and 11 percent had a sustained virologic response. In contrast, the corresponding proportions for those who drank three or more cups of coffee per day were 73 percent, 52 percent, 49 percent and 26 percent, respectively."Coffee intake has been associated with a lower level of liver enzymes, reduced progression of chronic liver disease and reduced incidence of liver cancer," said Neal Freedman, of the National Cancer Institute and lead author of this study. "Although we observed an independent association between coffee intake and virologic response to treatment, this association needs replication in other studies."Approximately 70 to 80 percent of individuals exposed to HCV become chronically infected. Worldwide, these individuals are estimated to number between 130 and 170 million. Higher coffee consumption has been associated with slower progression of pre- existing liver disease and lower risk of liver cancer. However, the relationship with response to anti-HCV treatment had not been previously evaluated.
