BEIJING/CHONGQING, Oct. 16 (Xinhua) -- A team of Chinese and American scientists have discovered the world's only evidence of co-existing human beings and dinosaur tracks in a remote county in southwest China's Chongqing Municipality, according to a paper published Saturday in the Geological Bulletin of China, a Chinese core academic journal.Qijiang County's Lianhua Baozhai, which means "Lotus Mountain Fortress" in Chinese, has a large number of dinosaur tracks as well as a well-preserved fortress and historical epigraph, forming a direct line of evidence that ancient Chinese people built a residence and lived there for a long time, said Xing Lida, one of three researchers with the project as well as a doctoral degree candidate with the Department of Biological Sciences of the University of Alberta in Canada.Chinese people could have lived here for more than 700 years, and the mud cracks, ripple marks and duck-billed dinosaur tracks were considered by them to be lotus leaf veins, water environment and lotus, respectively, which is why they named it the Lotus Mountain Fortress, Xing Lida told Xinhua."Research shows that dinosaur tracks impacted ancient Chinese place names and folklore, so place names and folklore can be major clues for us in tracing dinosaur tracks," Xing said.According to the paper, the Lotus Mountain Fortress dinosaur tracks, the largest track group of cretaceous dinosaurs in southwestern China, contains 350 to 400 footprints that had been preserved in many ways, including concave footprints, convex footprints and multilayered footprints.

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.

HANOI, Oct. 7 (Xinhua) -- Vietnam in cooperation with the United Nations Development Program (UNDP) and the Food and Agriculture Organization (FAO) organized a workshop here on Friday to finalize implementations in Phase 2 of the UN-Vietnam Joint Program to fight against Highly Pathogenic Avian Influenza (HPAI) during 2007-2011.The workshop is not only to review the achievements but also from that, Vietnam hopes to receive more supports from the UN agencies, said Bui Ba Bong, Vietnamese vice minister of Agriculture and Rural Development.According to the report, so far, Vietnam's project on prevention of HPAI has basically achieved the targets in terms of making plans, policies and strategies for the veterinary sector, assessing the impacts of destruction of poultry to the environment, controlling pandemic, and supporting vaccine inoculation, quarantine and control of the infected animals, said Bong.Vietnam showed great efforts in responding and preventing H5N1 pandemic during its occurrence in 2005-2006, evaluated UN agencies.In Phase 2, Vietnam achieved positive results in controlling and reducing the impacts of the pandemic, and promoting bio- security in livestock breeding. Therefore, UN pledged to continue assisting Vietnam in the future.The UN-Vietnam joint program to fight HPAI was designed to meet the needs of emergency assistance to control the avian and human influenza.Total fund of the program is 25 million U.S. dollars, of which over 18 million U.S. dollars was approved for Phase 2.

BEIJING, Oct.25 (Xinhua) -- The China Banking Regulatory Commission (CBRC), the country's top banking regulator, on Tuesday revealed detailed plans to encourage financial support for the country's small and micro-sized enterprises.In a supplementary notice issued to its previous support plan for financing small enterprises, the CBRC said banks should ensure that the growth of loans to small firms will not be slower than that of the average lending, and the growth should be higher than the level of the previous year.Also, commercial banks should give more support to enterprises that borrow less than 5 million yuan (787,401 U.S. dollars), and increase tolerance for non-performing loans to small and micro-sized firms, it said.The regulator has set detailed rules for the establishment of financial institutions serving small businesses, and encouraged banks to create financial instruments to support the development of small high-tech enterprises.The CBRC has also allowed banks to issue special financial bonds to boost financing for small businesses.By the end of August, outstanding loans to small and micro-sized enterprises stood at 14.6 trillion yuan, accounting for 27.2 percent of total lending.

BEIJING, Sept. 30 (Xinhuanet) -- Miners, construction workers and people in hotel and food service industry are most likely to smoke in the U.S., according to new research finding.The finding was contained in a report released Thursday by the U.S. Centers for Disease Control and Prevention (CDC).According to the finding, miners and people in hotel and food service have a cigarette smoking rate of 30 percent, followed closely by construction workers' 29.7 percent.Both rates are much higher than the average smoking rate of 19.6 percent among all U.S. working adults.Workers in the education services industry have the lowest smoking rate, with 9.7 percent, followed by the 10.9 percent of workers in company management, the report said.Low education levels are a factor in high smoking rates, along with poverty and gender, said Ann Malarcher, senior scientific adviser at the CDC."Although some progress has been made in reducing smoking prevalence among working adults," the report wrote, "additional effective employer interventions need to be implemented."Smoking kills an estimated 443,000 each year in the U.S., costing about 193 billion U.S. dollars annually in direct health care expenses and productivity loss.
