BEIJING, Oct. 13 (Xinhuanet) -- Tyrannosaurus rex dinosaur, the giant prehistoric predator, was even bigger and heavier than it was estimated previously, a new study found.The finding was contained in a study published Wednesday in the scientific journal PLoS ONE.Using three-dimension scanning and computer modeling, researchers analyzed five skeleton fossils of T. rex dinosaur, including "Sue", the largest and most complete T. rex specimen ever found.The analysis tipped the scale of "Sue" at 9 ton, some 30 percent more than it was expected."At their fastest, in their teenage years, they were putting on 11 pounds or 5 kilograms a day," said John Hutchinson of the Royal Veterinary College in London, who co-led the study.The larger body mass indicated the better agility and the stronger lower-leg muscles of the ancient monster, said the researcher."Sue" could have a top speed of about 10-25 miles per hour when it ran on the Great Plains of North America 67 million years ago, Hutchinson suggested.

TEHRAN, Dec. 8 (Xinhua) -- Iranian inventors ranked first in the Seoul International Invention Fair (SIIF) in South Korea, the official IRNA news agency reported on Thursday.The three-member Iranian team from Tabriz city of Iran's northwestern East Azerbaijan province was ranked first by winning one gold and one silver medals in the fields of development and environment, said the report.South Korea, the United States and Chinese Taipei were selected as other three top teams after Iran.The Seoul International Invention Fair was held in the COEX Korea Exhibition Center from December 1 to 4, at which Some 700 participants from 32 countries and regions took part.

NEW DELHI, Oct. 1 (Xinhua) -- Suspected encephalitis has killed over 100 children in the northern Indian state of Bihar since June, reported local media Saturday.At least 51 children in Bihar's Gaya district died of the epidemic in the last seven weeks, in the wake of the death of 55 children in a similar outbreak of the brain disease in another district of the state earlier, reported Indo-Asian News Service.Most of the children belong to a caste known for its absolute poverty.According to district health officials, all children have died at Anugrah Narain Medical College and Hospital in Gaya, about 100 km from the state capital Patna.The children reported high fever, followed by bouts of unconsciousness and convulsions.So far, more than 220 children with suspected encephalitis were admitted for treatment, with over two dozens of the children still battling for life, according to the report.Earlier, Indian Health and Family Welfare Minister Ghulam Nabi Azad has said clinical and epidemiological data suggested that there was an outbreak of acute encephalitis syndrome, resulting in 150 cases and 55 deaths, mostly among children, from early June to mid-July in the Muzaffarpur district of Bihar.

BEIJING, Oct. 29 (Xinhua) -- Chinese Premier Wen Jiabao and Chairman of the Central Military Commission Hu Jintao Saturday issued an order to publicize the Regulations on Resettlement of Ex-Servicemen, which will take effect from Nov. 1.Formulated with an aim to protect the legitimate rights and interests of ex-servicemen, the 53-article document highlights a series of initiatives designed for the appropriate placement of veterans.State organs, social groups, enterprises and public institutions should give preferential treatment to ex-servicemen while recruiting staff members or contract workers, according to the regulations.The regulations provide that demobilized soldiers who register for a civil servant examination or apply for a position in government institutions will be given preference.Those companies or organizations which recruit retired soldiers will enjoy favorable policies prescribed by current laws and regulations.

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.
