LONDON, March 15 (Xinhua) -- The moon would be in a "super position" on Saturday, which makes it a "supermoon" and the web is awash with myths about its implications such as connection to recent earthquakes, but that's not the case according to British experts.Technically the so-called "supermoon" means that the moon would be in its perigee, the closest point to earth in its orbit on March 19, and on top of that, it would also be a full moon at the same time.The massive earthquake in Japan just fueled the speculation that the gravitational pull of the "supermoon" will bring chaos to the Earth, such as earthquakes and volcanic activities.But "there is little that is special about perigee on March 19," said Dr. Robert Massey, deputy executive secretary of the Royal Astronomical Society. He said the moon will be around 360,000 km from the earth on that day, but this has happened at least 15 times during the last 400 years."There is no reason whatsoever to believe that there is a connection between the so-called 'supermoon' and the recent earthquake," Massey told Xinhua. "There are also no other 'abnormal' phenomena connected with a 'supermoon' other than the high tides that we experience twice every month."Massey was echoed by Dr. Bruce Malamud, a geophysicist in the Department of Geography at King's College London, who that: "A supermoon will not be able to actually influence at all the internal workings of our Planet Earth, as there is so much momentum and mass already stored up, that the actual effect is negligible.""The earthquake took place a full 8 days before the 'supermoon' meaning that the tidal forces exerted by the moon and sun together were near their minimum rather than maximum level, directly contradicting the fearmongers," said Massey.Calling the "supermoon" claims "bogus science," he questioned the motives of those who made such claims on the day that thousands of people died in a severe earthquake and the ensuing tsunami.

BEIJING, March 28 (Xinhuanet) -- Google Inc. is working with MasterCard Inc. and Citigroup Inc to develop a technology that could make mobile payments, according to media reports Monday.The new technology named "Nexus S Android" is embedded in Android mobile devices and allows customers to make purchases by waving their smartphones in front of a small reader at the checkout counter.Credit-card reader producer VeriFone Systems Inc, also involved in the new payment service, is developing contact-less devices that could allow people to pay with a wave or tap of credit card or a tap of smartphone.To use the service, holders of Citigroup-issued debit and credit cards must activate a mobile-payment application developed for one current model of Android phones. More models will be coming as the technology advances.Besides mobile payment, consumers would also be able to get targeted ads or discount offers, manage credit-card accounts and track spending through an application on their smartphones.Due to the deliberate design of the technology, customers have no need to worry about the security of their payment information. Nick Holland, a mobile-transactions analyst at Yankee Group, said the new technology is more sophisticated than credit cards with a magnetic stripe.With the coming service, Google is aiming to boost its advertising business by offering retailers more data about their customers and help them target ads and discount offers to mobile-device users near their stores.An insider told that Google was not expected to get a cut of the transaction fees.The service is expected to be released this year. Once released, it will broaden the uses of smartphones for everyday activities—from chatting to emailing to shopping.

RIO DE JANEIRO, March 25 (Xinhua) -- The number of dengue fever cases in Rio de Janeiro city this year has already surpassed 10,000, local health authorities said on Friday.According to the city's Health Secretariat, in less than three months, the number of confirmed dengue fever cases in Rio reached 10,158, exceeding the figures registered in the entire years of 2009 (2,723) and 2010 (3,120).In Rio de Janeiro state, the number of confirmed dengue fever cases reached 20,150, and the death toll rose to 18.This week, the first two cases of type-4 dengue fever in Rio de Janeiro state were confirmed in the city of Niteroi. The type-4 dengue fever is not more dangerous than the other types, but as the disease had not been registered in the region before, the local population has no immunity to it.As there are four different types of dengue fever, a person can develop the disease several times.The last epidemic of dengue fever in Rio de Janeiro state occurred in 2008 when 174 people died of the disease and some 250,000 cases of dengue were registered.

LOS ANGELES, May 1 (Xinhua) -- Middle-aged adults who sleep too less or too much may be more likely to suffer cognitive decline, a new study suggests.According to the study, less than six hours of sleep each night is considered too little and more than eight hours as too much for middle-aged adults.The study, conducted by researchers at University College London Medical School, was published May 1 in the American medical journal Sleep.The researchers conducted the study in two periods -- the 1997- 1999 period and the 2003-2004 period. The participants were asked how many hours they slept on an average week night, and were asked the same question in 2003-2004 after an average 5.4 years of follow-up.The researchers compared those who reported changes in their sleep patterns with people whose sleep duration stayed the same over the course of the study.In the follow-up, each individual was given a battery of standard tests to assess his or her memory, reasoning, vocabulary, global cognitive status and verbal fluency.The study findings show that women who slept seven hours per night had the highest score for every cognitive measure, followed by those who had six hours of sleep. For men, cognitive function was similar for those who reported sleeping six, seven or eight hours.However, less than six hours of sleep -- or more than eight hours -- were associated with lower scores."Sleep provides the body with its daily need for physiological restitution and recovery," explained Jane Ferrie, a senior research fellow in the department of epidemiology and public health at the school. "While seven hours a night appears to be optimal for the majority of human beings, many people can function perfectly well on regular sleep of less or more hours."However, since most research has focused on the effects of sleep deprivation on biological systems, it is not yet fully understood why seven hours is optimal -- or why long sleeping appears to be detrimental, Ferrie said."Chronic short sleep produces hormones and chemicals in the body which increase the risk of developing heart disease and strokes, and other conditions like high blood pressure and cholesterol, diabetes and obesity," she added.
