WASHINGTON, April 5 (Xinhua) -- NASA and co-researchers from the United States, the Republic of Korea and Japan have found a new mineral named "Wassonite" in one of the most historically significant meteorites recovered in Antarctica in December 1969, the U.S. space agency said on Tuesday in a statement.The new mineral was discovered within the meteorite officially designated Yamato 691 enstatite chondrite. The meteorite likely may have originated from an asteroid orbiting between Mars and Jupiter. Wassonite is among the tiniest, yet most important, minerals identified in the 4.5-billion-year-old sample.The research team, headed by NASA space scientist Keiko Nakamura-Messenger, added the mineral to the list of 4,500 officially approved by the International Mineralogical Association."Wassonite is a mineral formed from only two elements, sulfur and titanium, yet it possesses a unique crystal structure that has not been previously observed in nature," said Nakamura-Messenger.In 1969, members of the Japanese Antarctic Research Expedition discovered nine meteorites on the blue ice field of the Yamato Mountains in Antarctica. This was the first significant recovery of Antarctic meteorites and represented samples of several different types.As a result, the United States and Japan conducted systematic follow-up searches for meteorites in Antarctica that recovered more than 40,000 specimens, including extremely rare Martian and lunar meteorites.Researchers found Wassonite surrounded by additional unknown minerals that are being investigated. The mineral is less than one-hundredth the width of a human hair or 50x450 nanometers. It would have been impossible to discover without NASA's transmission electron microscope, which is capable of isolating the Wassonite grains and determining their chemical composition and atomic structure."More secrets of the universe can be revealed from these specimens using 21st century nano-technology," said Nakamura- Messenger.The new mineral's name was approved by the International Mineralogical Association. It honors John T. Wasson, professor at the University of California, Los Angeles. Wasson is known for his achievements across a broad swath of meteorite and impact research, including the use of neutron activation data to classify meteorites and to formulate models for the chemical makeup of bulk chondrites.

LOS ANGELES, April 14 (Xinhua) -- Vegetarians experience a much lower risk of metabolic syndrome than non-vegetarians, U.S. researchers have found.Researchers at Loma Linda University in California based their findings on analysis of more than 700 adults randomly sampled from a long-term study of the lifestyle and health of almost 100,000 Seventh-day Adventist Christians across the United States and Canada.While 25 percent of vegetarians had metabolic syndrome, the number significantly rises to 37 percent for semi-vegetarians and 39 percent for non-vegetarians, according to the study published in the April issue of the journal Diabetes Care.The findings showed that the risk of developing metabolic syndrome is 36 percent lower among vegetarians than non- vegetarians.This means that vegetarians are less likely to develop heart disease, diabetes and stroke -- three major conditions that are closely linked with metabolic syndrome, the researchers say.The study also found that vegetarians, though slightly older than non-vegetarians, had lower triglycerides, glucose levels, blood pressure, waist circumference, and body mass index (BMI). Semi-vegetarians, meanwhile, also had a significantly lower BMI and waist circumference compared to those who ate meat more regularly.The findings will not be affected by other factors such as age, gender, race, physical activity, calories consumed, smoking, and alcohol intake, the researchers say."In view of the high rate of metabolic syndrome in the United States and its deleterious health effects, we wanted to examine lifestyle patterns that could be effective in the prevention and possible treatment of this disorder," says lead researcher Nico S. Rizzo, PhD."I was not sure if there would be a significant difference between vegetarians and non-vegetarians, and I was surprised by just how much the numbers contrast," he says. "It indicates that lifestyle factors such as diet can be important in the prevention of metabolic syndrome."

BEIJING, May 5 (Xinhua) -- A Chinese official has vowed to take every possible measure to ensure food safety in the country, saying the government has decided to launch national overhauls this year on sectors including milk products, cooking oil, health foods, meat and alcohol.Zhang Yong, director of the executive office of the food safety commission under the State Council, or Cabinet, said in an interview with Xinhua that the food and drinks in these five sectors are consumed in enormous quantities each day and they will do great harm and have an extensive social impact if a problem arises.Through special campaigns to overhaul these five sectors and by solving the most prominent problems, the government aims to accumulate experiences and create administrative systems in a bid to prevent food safety incidents and raise the overall level of food safety, Zhang said.The central government initiated a prolonged and stringent fight against the illegal use of additives in food last month, detailing measures to intensify supervision, upgrade safety limits, and increase penalties for violators.Vice Premier Li Keqiang warned of the great harm from illegal additives in food at a high-profile national meeting last month, promising a "firm attitude, iron-hand measures and more efforts" in dealing with the problem.Zhang Yong admitted "China is in a period when food safety incidents are likely to arise" since the country's food industry is on a fast track for development and a large number of food producers and catering operators are running their businesses in a small-scale or scattered way."It makes it more difficult for the government departments to conduct supervision on food quality and safety," Zhang said."We will take every possible measure to consolidate the feeble foundation to ensure food safety and curb food safety incidents as soon as possible," he said.According to Zhang, the government will also make efforts to improve supervision and emergency handling capabilities, raise the credibility and personnel quality of the involved enterprises, and severely punish violators.The Chinese government made the moves after a series of food safety scandals emerged despite the authorities' efforts to revamp the country's food industry. They included steamed buns dyed with unidentified chemicals, the use of "lean meat powder", also known as clenbuterol, a kind of fat-burning drug, as well as the use of illegal cooking oil known as "gutter oil."

ADDIS ABABA, Jan. 28 (Xinhua) -- Fruitful results have been achieved some one year after the fourth ministerial meeting of the Forum on China-Africa Cooperation (FOCAC), Chinese envoy and Assistant Foreign Minister Liu Zhenmin told Xinhua here on Friday.Liu was in the Ethiopian capital Addis Ababa to attend the 16th African Union (AU) summit as special envoy of the Chinese government.During the FOCAC ministerial meeting held in November 2009 in Sharm el-Sheikh, Egypt, the Chinese government announced eight new measures of promoting Sino-African cooperation.Since then, China has been actively implementing various programs and projects according to the eight new measures, Liu said.The “China-Africa Science and Technology Partnership Program” and the “China-Africa Joint Research and Exchange Program” have been launched, Liu said, adding that the aid program of agricultural demonstration center is in smooth implementation process.Meanwhile, China is actively working on establishing the China-Africa partnership in addressing climate change, and is strengthening communication and coordination with Africa on the issue of climate change, Liu said.The Chinese envoy added that various programs and events such as the China-Africa Agricultural Cooperation Forum, the “African Culture in Focus 2010” activities, and the “20+20 Cooperation Plan of Chinese and African Institutions of Higher Learning” have been launched or successfully held. He said these events have promoted the comprehensive development of China-Africa relations.A wide range of other measures are also being carried out in an active manner, according to Liu.The year 2011 is key to the implementation of the measures announced on the fourth ministerial meeting of FOCAC, Liu stressed.To this end, China will continue strengthening communication and coordination with African countries, carrying out close cooperation and pushing forward the development of the China-Africa new strategic partnership, he pledged.

SAN FRANCISCO, April 22 (Xinhua) -- Apple and Google collect smartphone users' location information as part of their race to build massive databases, The Wall Street Journal reported on Friday after analyzing data and documents.According to the report, security analysts with the newspaper found that Apple's iPhone and smartphones running Google's Android operating system regularly transmit users' locations back to the two companies respectively, which is part of their race to build databases capable of pinpointing people's locations via smartphones.A report by research firm Gartner indicated that the market for location-based services is expected to rise to 8.3 billion U.S. dollars in 2014 from the current 2.9 billion dollars.In the case of Google, a security analyst with The Wall Street Journal said an HTC Android phone collected name, location, signal strength of any nearby Wi-Fi networks, and a unique phone identifier every few seconds and transmitted the data to Google at least several times an hour."All location sharing on Android is opt-in by the user," Google said in a statement to technology blog site All Things Digital, in response to the concern that how Android system uses location information."We provide users with notice and control over the collection, sharing and use of location in order to provide a better mobile experience on Android devices. Any location data that is sent back to Google location servers is anonymous and is not tied or traceable to a specific user," said the statement.Worries on the iPhone tracking issue surfaced on Wednesday after two British researchers announced at a technology conference in California that iPhone has been collecting users' location information and storing the data for extended periods of time.The researchers said starting on June 21 2010, after the release of iOS 4 mobile operating system, iPhones began logging and storing location information in a file, which shows the users' latitude and longitude and is timestamped to the second. They noted the information is not encrypted on the phone or on the iPhone backups made by iTunes and the file is also persistent, transferring itself to a new iOS device when the old one is replaced.They added they had no evidence that the file was being transmitted to Apple.On Thursday, U.S. congressman Edward Markey reacted angrily to the news in a letter to Apple CEO Steve Jobs, which is posted on Markey's official website.Markey asked Jobs to make a response within 15 business days or no later than May 12, saying "Apple needs to safeguard personal location information of its users to ensure that an iPhone doesn't become an iTrack."Apple has made no comment on the issue so far, but a letter it sent to U.S. Congress last July came under spotlight. In the letter, Apple said it collects Wi-Fi and GPS information when the phone is searching for a cellular connection and gathers the data to help build a "database with known location information."
