BEIJING, Oct. 11 (Xinhuanet) -- Scientists have discovered that blind optimism is related to brain's frontal lobes which are associated with processing errors, according to a British study published Monday in the journal Nature Neuroscience.Scientists at the University College of London scanned brains of volunteers who were asked to estimate their personal likelihood of involving in negative events, like a divorce or cancer,  before and after given the average probability of these events occurring.They found that the volunteers who estimated lower probability (or the more optimistic ones) than the given one raised their estimates a little bit later while those estimated higher probability altered their estimates much more.Through the brain scanner, scientists saw there was less activity in the volunteers' frontal regions when the information given was worse than expected while more activity when the information was better than expected. It suggested that the more optimistic people neglected the negative predictions."The more optimistic we are, the less likely we are to be influenced by negative information about the future," said Dr. Tali Sharot, lead author of the study. He added being optimistic clearly had some benefits, "but it can also mean that we are less likely to take precautionary action, such as practising safe sex or saving for retirement. So why don't we learn from cautionary information?"

WASHINGTON, Nov. 9 (Xinhua) -- An international team of researchers funded by NASA and the National Science Foundation (NSF) will travel next month to one of Antarctica's most active, remote and harsh spots to determine how changes in the waters circulating under an active ice sheet are causing a glacier to accelerate and drain into the sea, the U.S. space agency announced Wednesday.The science expedition will be the most extensive ever deployed to Pine Island Glacier. It is the area of the ice-covered continent that concerns scientists most because of its potential to cause a rapid rise in sea level. Satellite measurements have shown this area is losing ice and surrounding glaciers are thinning, raising the possibility the ice could flow rapidly out to sea.The multidisciplinary group of 13 scientists, led by Robert Bindschadler, emeritus glaciologist of NASA's Goddard Space Flight Center, will depart from the McMurdo Station in Antarctica in mid- December and spend six weeks on the ice shelf. During their stay, they will use a combination of traditional tools and sophisticated new oceanographic instruments to measure the shape of the cavity underneath the ice shelf and determine how streams of warm ocean water enter it, move toward the very bottom of the glacier and melt its underbelly."The project aims to determine the underlying causes behind why Pine Island Glacier has begun to flow more rapidly and discharge more ice into the ocean," said Scott Borg, director of NSF's Division of Antarctic Sciences, the group that coordinates all U.S. research in Antarctica. "This could have a significant impact on global sea-level rise over the coming century."

VIENNA, Oct. 31 (Xinhua) -- Visiting Chinese President Hu Jintao met his Austrian counterpart Heinz Fischer here Monday and laid out a multi-point proposal to further strengthen bilateral cooperation.During the meeting, Hu spoke highly of the ties between the two countries, saying that China values its relations with Austria and is willing to join hands with Austria to elevate bilateral ties to a higher level.Then he proposed that the two sides enhance their political relationship based on equality and mutual trust, continue with their frequent high-level contacts and steer bilateral relations from a strategic and long-term perspective.The two countries should also expand their mutually beneficial economic and trade relations, he said, while calling for concerted efforts to fight trade protectionism and encourage mutual investment so as to achieve a balanced, diversified and sustainable trade relationship.Visiting Chinese President Hu Jintao (L) shakes hands with his Austrian counterpart Heinz Fischer (R) in Vienna, Austria, Oct. 31, 2011. Hu Jintao held talks with Heinz Fischer in Vienna Monday.China is willing to import more goods from Austria and to work with Austria to seek cooperation with third countries in Central and Eastern Europe, said the Chinese president, who also asked Austria to create favorable conditions for Chinese investors in Austria.Meanwhile, Hu urged Vienna to play a more active role in pushing for the EU's recognition of China's full market economy status and for a lift of the bloc's restrictions on high-tech exports to China.In the culture sphere, the two sides should promote people-to-people exchanges and boost cooperation in culture, eduction and media among others, Hu said.In addition, the two countries should also deepen cooperation in multilateral mechanisms to jointly push for a more just and fairer international political and economic order, Hu said.China, he added, is willing to enhance cooperation and coordination with Austria on important issues such as global economic governance, climate change, energy security and peaceful settlement of international disputes.History has proven that as long as the two sides understand and support each other, and respect each other's social systems and development models, the bilateral relationship can achieve long-term, steady and healthy development, Hu said.Fischer, for his part, said that he fully agrees with Hu's proposal, adding that his country is willing to enhance cooperation with China in culture, science and technology and tourism and expand coordination in the United Nations and other multilateral frameworks.

NANCHANG, Oct. 1 (Xinhua) -- A copper sword dating back more than 2,200 years has been discovered in east China's Jiangxi Province, local archaeologists said.The design and shape of the sword indicate that it was forged during the Warring States Period (475 BC - 221 BC), according to Li Guoli, curator of the Nanchang Museum, where the sword is currently being stored.Despite having little aesthetic or scientific value due to a lack of decor or inscriptions, the sword still offers insights into the type of military equipment used during the period, Li said.The identity of the sword's original owner and the precise location where the sword was forged and used are still unknown, Li said.The sword was discovered by a laborer surnamed Xiong in Jiangxi's capital of Nanchang. Xiong found the sword while sorting and cleaning stones that had been dredged up from a riverbank.An argument between Xiong and another worker who was trying to claim the sword aroused attention from the local law enforcement, who then convinced Xiong to turn the sword over to archaeological authorities.
