SAN FRANCISCO, July 12 (Xinhua) -- Google+, the social networking service Google unveiled only two weeks ago, is estimated to surpass 10 million users on Tuesday, possibly becoming the fastest growing product in the history of the Internet.According to Ancestry.com founder Paul Allen (not the co- founder of Microsoft), after passing 10 million users, Google+ " could reach 20 million users by this coming weekend if they keep the Invite Button available."Allen looks for last names on Google+ and compares them with U. S. Census Bureau data on the popularity of surnames to statistically project the number of Google+ users."Since I have been tracking this same cohort of surnames from my first day, I am able to accurately measure growth over time," he said in a blog post on Google+ website.Google so far has not released any details about the Google+ users or the number of users. Speaking at a press event last Thursday in Sun Valley in the U.S. state of Idaho, former Google CEO and current Executive Chairman Eric Schmidt said there are " millions" of users.Industry watchers think the estimate may not be completely accurate, but Allen should be capturing the growth trajectory of Google+, which shows that a social network could undergo an exponential growth in its early days.

WELLINGTON, Sept. 27 (Xinhua) -- New Zealand and Japanese scientists are teaming up to develop healthier foods under two government-funded "functional foods" projects.One project, to be led by New Zealand's Massey University, will work with New Zealand food companies to create and develop a functional food with specific health enhancing effects for menopausal women, New Zealand Science and Innovation Minister Wayne Mapp announced Tuesday.The other project, to be led in New Zealand by Plant and Food Research, would use mass spectrometry to develop a "metabolic atlas" of the chemical composition of allium vegetables, such as onions and garlic, which the horticultural industry could use to develop new food products with health benefits.Mapp said the two research projects would be awarded a total of 1 million NZ dollars (782,000 U.S. dollars) in funding to strengthen collaborative research relationships between New Zealand and Japan, Mapp said."These research projects have strong commercial potential, including through the Japanese market, and so have the potential to benefit our economy," said Mapp."The government is committed to building and strengthening research relationships with other countries that will achieve world-class scientific results and lead to new innovative technologies."The two projects awarded funding under Ministry of Science and Innovation's Japan Science and Technology Agency (JST) funding round focus on functional foods. The ministry and Japan each fund half the cost of each research project awarded funding.

WELLINGTON, July 29 (Xinhua) -- Scientists from around the world will gather on the east coast of New Zealand next week to discuss proposals to study "silent" earthquakes by drilling into the seabed.Silent quakes, also known as slow slip events, occur on the boundaries of the earth's tectonic plates, where one plate dives under another in areas known as subduction zones, and are slower than normal quakes, taking weeks or months to occur rather than seconds, and are rarely felt on the surface.About 70 scientists from 10 countries will convene in the city of Gisborne, which lies near the site of a major fault line and where scientists first identified silent earthquakes in 2002.Slow-slip events were first discovered with the advent of new measurement technologies on the west coast of Canada about 15 years ago and have since been recorded at about a dozen locations around the world, including four sites around New Zealand, said a spokesperson for New Zealand's Institute of Geological and Nuclear Sciences (GNS Science).About eight slow-slip episodes have occurred under Gisborne since 2002 at roughly two-year intervals.Scientists have proposed numerous theories to explain the phenomenon, but testing the theories is difficult as silent quakes happen many kilometers below ground."The best way to understand the true cause of slow-slip events is to drill into and sample the area on the plate boundary fault where they are known to occur, and monitor a whole range of physical and chemical properties at the plate interface," said Laura Wallace, of GNS Science.

BEIJING, Sept. 2 (Xinhuanet) -- Firefighters who worked in the wreckage of the World Trade Center in 2001 were 19 percent more likely to develop cancer than those who were not there, according to a study.The study, published Thursday in the British medical journal The Lancet, surveyed cancer occurrence in nearly 10,000 male firefighters in the seven years after Sept. 11, 2001. (There were too few women to create a meaningful sample size.)The 9/11 attacks occurred on Tuesday, Sept. 11, 2001. As a result, the World Trade Center collapsed, and nearly 3,000 Americans killed. Among the 2,753 victims killed in the World Trade Center were 343 firefighters.There were 263 cancer cases in the exposed population, showing a cancer rate 19 percent higher than that of the group not exposed.The study indicated that cancers like melanoma, non-Hodgkin’s lymphoma, thyroid and prostate cancer occurred more frequently among exposed firefighters than in the general population. But occurrences of lung cancer did not increase.The findings “provide information that there may be a significant cancer risk for these people”, said Dr. James Melius, the administrator of the New York State Laborers’ Health and Safety Trust Fund and one of the peer reviewers of the study.But the results were far from conclusive. “This is not an epidemic,” said Dr. David J. Prezant, a lead researcher and the chief medical officer for the New York Fire Department.

SAN FRANCISCO, July 29 (Xinhua) -- Apple has ousted Nokia as the world's largest smartphone maker as global mobile phone market grew more than 11.3 percent in the second quarter of 2011, according to two separate market research studies.After becoming the largest smartphone vendor in terms of revenue and profits, Apple has become the world's largest smartphone vendor by volume with 18.5 percent market share, said the latest research from Strategy Analytics released on Friday.The Cupertino, California-based company sold 20.3 million iPhones in the second quarter,up 142 percent compared with the same period a year earlier.Samsung's shipments of 19.2 million units grew a huge 520 percent year over year, accounting for 17.5 percent global smartphone market share in the second quarter of 2011.Apple and Samsung overtook long-time volume leader Nokia for the two spots. The Finnish mobile phone giant accounted for 15.2 percent of global smartphone market share in the last quarter, which is less than half of what it was just one year earlier.In the second quarter of 2010, Nokia was the No.1 smartphone maker by volume in the world with 38.1 percent of market share. The industry is now waiting Nokia's pending transition to Windows Phone 7.According to a separate report by International Data Corporation (IDC) released on Thursday, the worldwide mobile phone market grew by 11.3 percent year over year in the second quarter of 2011 despite a decline of the feature phone market for the first time in almost two years.The feature phone market was down by 4 percent in the last quarter, said the IDC Worldwide Mobile Phone Tracker report. It noted that the decline in shipments was mainly in economically mature regions, such as the United States, Japan and Western Europe, as users making rapid transition to smartphones.The shrinking feature phone market had a great impact on some of the world's largest suppliers of mobile phones, such as Nokia, which is losing share in the feature phone category to low-cost suppliers, said the report.For the overall market, global mobile phone vendors shipped 365. 4 million units in the second quarter, compared to 328.4 million units in the same period last year, with Nokia still holding the top spot with a market share of 24.2 percent, followed by Samsung, LG Electronics, Apple and ZTE.But the 11.3 percent growth was lower than IDC's forecast for the quarter and also below the 16.8 percent growth in the first quarter of 2011.IDC said the feature phone forecast isn't expected to be any rosier in the future and the shipment growth of feature phones won 't exceed 1.1 percent in the coming years.
