BEIJING, Jan. 22 (Xinhua) -- China restored 23,000 hectares of wetlands in 2011, according to the latest figures from the State Forestry Administration (SFA).An SFA spokesman said China reinforced wetland protection in 2011 by increasing subsidies in protecting wetlands. In the year the country carried out 42 wetland protection projects, increased 330,000 hectares of protected wetland areas, added four wetlands of international importance and 68 national wetland parks.The spokesman said in 2012 the country will further step up wetland protection and restoration, finish the second national wetland resources investigation and carry out pilot projects in assessing healthy conditions of the wetland ecological system.So far China has built more than 550 wetland natural reserves, 37 wetlands of international importance, which were listed in the Ramsar international wetland convention, and 100 national wetland parks. About half of the country's natural wetlands have been brought under effective protection, the SFA said.

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.

WASHINGTON, Dec. 7 (Xinhua) -- Drugs that affect the levels of an important brain protein involved in learning and memory reverse cellular changes in the brain seen during aging, according to an animal study published Wednesday in the Journal of Neuroscience. The findings could one day aid in the development of new drugs that enhance cognitive function in older adults.Aging-related memory loss is associated with the gradual deterioration of the structure and function of synapses (the connections between brain cells) in brain regions critical to learning and memory, such as the hippocampus.Recent studies suggested that histone acetylation, a chemical process that controls whether genes are turned on, affects this process. Specifically, it affects brain cells' ability to alter the strength and structure of their connections for information storage, a process known as synaptic plasticity, which is a cellular signature of memory.In the current study, Cui-Wei Xie, of the University of California, Los Angeles, and colleagues found that compared with younger rats, hippocampi from older rats have less brain-derived neurotrophic factor (BDNF) -- a protein that promotes synaptic plasticity -- and less histone acetylation of the Bdnf gene. By treating the hippocampal tissue from older animals with a drug that increased histone acetylation, they were able to restore BDNF production and synaptic plasticity to levels found in younger animals."These findings shed light on why synapses become less efficient and more vulnerable to impairment during aging," said Xie, who led the study. "Such knowledge could help develop new drugs for cognitive aging and aging-related neurodegenerative diseases, such as Alzheimer's disease," she added.

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?"

BEIJING, Jan. 14 (Xinhua) -- A Spring Festival gala was held at the Great Hall of the People Saturday to entertain the country's military officers, soldiers and civilians.Representatives of officers and soldiers in the military units and armed police forces in Beijing as well as some Beijing residents attended the gala.President Hu Jintao and other top Chinese leaders including Wu Bangguo, Jia Qinglin, Li Changchun, Xi Jinping, Li Keqiang, He Guoqiang and Zhou Yongkang were also present at the gala.Hu expressed greetings to the audience and extended his good wishes for them, ahead of the traditional Spring Festival, or the Chinese Lunar New Year, which falls on Jan. 23 this year.
