BEIJING, Jan. 7 (Xinhua) -- The two-day National Financial Work Conference concluded Saturday, laying out development plans for the financial sector in the coming five years, according to a statement released after the meeting.Chinese Premier Wen Jiabao was present at the conference and delivered a keynote speech.Such a conference is held every five years. Similar meetings were held in 1997, 2002 and 2007.

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, Jan. 25 (Xinhua) -- China's meteorological authority said Wednesday that most parts of China will continue to be in the grip of cold with temperatures remaining low over the next few days.Snowy weather is forecast to continue in the country's southern regions, and freezing rain is expected to hit parts of Guizhou and Hunan provinces, the National Meteorological Center said in a statement on its website.Parts of the country's northwest areas expected to see light snow or drizzle.Meanwhile, fog will shroud most parts of the country's southern areas Wednesday morning, reducing visibility in parts of Yunnan, Hunan, Jiangxi, and Zhejiang provinces to less than 1,000 meters, while smog is forecast to hit some areas of Jiangsu Province, according to the statement.

BEIJING, Oct. 26 (Xinhuanet) -- The question, why the first documented supernova was super-sized and grew so fast, has puzzled astronomers for centuries. Now it is solved by US researchers.The supernova, an exploded star, was observed in 185 A.D. and documented as a mysterious "guest star" by Chinese astronomers. It was visible for eight months.Scientists later found the supernova, 8,000 light years away, was a bigger-than-expected supernova remnant. BBC reported that if the infrared light it emits could be seen by human eyes, it would appear to be as large as the full Moon in the sky.Through observations in space telescopes, researchers of a latest study revealed that the explosion took place in a cavity in space, which allowed the star's remains to travel out much faster and farther. The study was published online in the Astrophysical Journal Monday.The supernova was "two to three times bigger than we would expect for a supernova that was witnessed exploding nearly 2,000 years ago. Now, we've been able to finally pinpoint the cause," stated Brian Williams, lead author of the study and an astronomer at North Carolina State University in Raleigh.

BEIJING, Oct. 21 (Xinhua) -- China on Friday urged the European Union (EU) to recognize its full-market economy status at an early date and properly settle trade disputes amid the tumbling world economy."China hopes Belgium will exert its influence to push for an early recognizing of China's full-market economy status and remind the EU to be cautious on and restrain from using trade remedy measures," Vice Premier Wang Qishan told visiting Crown Prince Philippe of Belgium.Wang urged the 27-member bloc, also China's largest trade partner, to properly settle trade disputes with China during the talks at Diaoyutai State Guesthouse in downtown Beijing.Chinese Vice Premier Wang Qishan (R) shakes hands with Belgian Crown Prince Philippe in Beijing, capital of China, Oct. 21, 2011."China has contributed a lot to the world economy by recording a 9.4 percent growth in the first three quarters of this year while adjusting its economic structure and managing inflation expectations," Wang said.Prince Philippe, accompanied by a 450-member business delegation, is here to tap the Chinese market and seek investments from China, the world's top holder of foreign exchange reserves.During the 10-day trip, the delegation will visit the Chinese cities of Tianjin, Guangzhou, Shenzhen, Shanghai and Chongqing and is expected to sign about 40 contracts.Wang said China will expand two-way investment with Belgium, and enhance support to the two states' small and medium-sized enterprises via the China-Belgium direct equity investment fund.China-Belgium trade has continued to surge since the two states forged diplomatic ties in 1971, when the bilateral trade volume was only 20 million U.S. dollars, much less than the 22.1 billion U.S. dollar record in 2010."We could expand cooperation in two-way investment, trade, finance, chemical industry, environmental protection, logistics, and green economy," Wang said.
