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.

BEIJING, March 29 (Xinhuanet) -- A new study has found that rejection can literally hurt in the same way as physical pain does, according to media reports Tuesday.Researchers found that intense emotional pain, such as feelings of rejection after a breakup of a relationship, can trigger brain activities similar to when people suffer physical pain.The research findings were published in Tuesday's Proceedings of the National Academy of Sciences.The study followed 40 volunteers who experienced unwanted romantic breakups in the past six months, and the researchers analyzed their brain activity during two "painful" situations.The results showed that the two situations, thinking about the loss of their ex-partner and experiencing mild physical pain similar to holding a very hot coffee cup, caused response in the overlapping parts of the brain."This tells us how serious rejection can be sometimes," said study author Edward E. Smith, director of cognitive neuroscience at Columbia University. Smith added. "Our ultimate goal is to see what kind of therapeutic approach might be useful in relieving the pain of rejection."

KUALA LUMPUR, Feb. 3 (Xinhua) -- Malaysian Prime Minister Najib Razak wishes all Chinese in the world a happy Chinese New Year on Thursday in an exclusive interview with Xinhua News Agency at his official residence in Federal Administrative Center Putrajaya."I would like to wish all Chinese in the world, wherever they are at any part of the world, a very happy Chinese New Year through Xinhua News Agency,"Najib said.

"I hope this relationship will bring much benefit to both Malaysia and China, I wish it can be developed further and strengthen and deepen this important relationship."The prime minister had his Thursday occupied, attending numerous Spring Festival Open House, including the one held by the Malaysian Chinese Association (MCA) - the largest party that represents the ethnic Chinese in the country's ruling coalition.Thousands attended the open house event at the party's headquarters, many of whom were tourists.Malaysian leaders, ambassadors and attaches from foreign embassies were among the invited guests at the event.The Open House is a Malaysian tradition during celebrations where people open their doors to welcome guests and even strangers into their homes.He then held a live teleconference with Malaysians residing in seven cities in the world, including Guangzhou, China, and sent his greetings.About 26 percent of Malaysia's 27 million population are ethnic Chinese.

BEIJING, Feb. 13 (Xinhua) -- China will impose tax on the one-off subsidy to people taking early retirement, the State Administration of Taxation (SAT) said Sunday.The SAT said the early retirement subsidy, which is not tax-free retirement income, should be imposed with personal income tax.However, the tax will be calculated after the subsidy is divided by the months between the date of the completion of retirement formalities and the corresponding legal retirement date, the SAT said.
