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, Nov. 8 (Xinhua) -- Children with autism have more brain cells and heavier brains compared to typically developing children, according to a study to be published on Wednesday in the Journal of the American Medical Association.The small, preliminary study provides direct evidence for possible prenatal causes of autism.The prefrontal cortex is involved in various higher order functions such as language and communication, social behavior, mood, and attention. Children who have autism tend to show deficits in such functions.Eric Courchesne, of the University of San Diego School of Medicine Autism Center of Excellence, and colleagues conducted direct counts of brain cells in specific regions of the prefrontal cortex in postmortem brains of seven boys who had autism and six typically developing males, ranging in age from 2-16 years. Most participants had died in accidents, but the researchers did not base their selection on causes of death.The researchers found that children with autism had 67 percent more neurons in the prefrontal cortex and heavier brains for their age compared to typically developing children. Since these neurons are produced before birth, the study's findings suggest that faulty prenatal cell birth or maintenance may be involved in the development of autism. Another possible factor that may contribute to the neuronal excess is a reduction in apoptosis, or programmed cell death, which normally occurs during the third trimester and early postnatal life.Though small, this preliminary study examined all relevant postmortem tissue available at the time. The relative scarcity of tissue from very young children may limit future research as well, but efforts to include a larger number of samples are needed to confirm these findings and to identify patterns of age-related changes in autism, the researchers say."Earlier studies of head circumference and early brain overgrowth have pointed us in this direction, but there have been few quantitative neuroanatomical studies due to the lack of postmortem tissue from children with autism," said Thomas Insel, director of the National Institute of Mental Health, in a statement. "These new results, along with an earlier study reporting altered wiring of the prefrontal cortex, focus our attention on this critical area of the brain in autism."

CANBERRA, Oct. 4 (Xinhua) -- A visiting U.S. obesity expert, Kelly Brownell, on Tuesday called on Australia to make a start on taxing high-sugar soft drinks.As director of U.S. Yale University's Rudd Center for Food Policy and Obesity, Professor Brownell is in Canberra of Australia to attend the 46th Australian Psychological Society Annual Conference.He said soft drinks were a good place to start in the taxing of high-sugar foods because they were the single greatest source of added sugar in the average person's diet, had absolutely no nutritional value, were marketed aggressively and were linked with the risk for obesity and diabetes.While obesity has overtaken smoking as the leading cause of premature death and illness in Australia, he said the government should tax soft drinks in the same way it taxes cigarettes, because research showed that taxes had been the strongest influence on falling rates of consumption."We have seen how effective tobacco taxes have been in reducing rates of smoking, so there is no reason to believe such taxes wouldn't be as effective in reducing the consumption of high sugar and fat foods," Brownell, who was named by Time magazine as one of the 100 most influential people in the world, told the conference in Canberra on Tuesday. "A soft-drink tax is a good place to start. "Earlier this week, Denmark became the first country to impose a tax on food containing saturated fats, and Brownell said he completely supports Denmark's policy and that governments should act courageously to do whatever is effective in encouraging better eating habits.According to the Organisation for Economic Co-operation and Development report, Australia is ranked as one of the fattest nations in the developed world. The prevalence of obesity in Australia has more than doubled in the past 20 years, with more than 17 million Australians are overweight or obese.

SAN FRANCISCO, Oct. 4 (Xinhua) -- Apple Inc. on Tuesday unveils iPhone 4S, the much-anticipated latest generation of iPhone.At the event held at Apple headquarters in Cupertino, California, U.S., newly installed Chief Executive Officer Tim Cook took stage to give a general introduction of Apple's products, his first product presentation after taking over the reins from Steve Jobs in August.According to Apple, there are several key features that make the new iPhone 4S different from the current iPhone 4. With a 3.5- inch widescreen multitouch display, the new device features dual- core A5 processor, the chip used in the iPad 2, and a higher- resolution eight megapixel camera which can grab 73 percent more light and take a 1080p high-definition video.The battery can support internet use up to six hours on 3G network and nine hours on Wi-Fi, as well as talk time up to eight hours on 3G and 14 hours on 2G. U.S., newly installed Chief Executive Officer Tim Cook takes stage to give a general introduction of Apple's products, Oct. 4, 2011. Apple Inc. on Tuesday unveils iPhone 4S, the much-anticipated latest generation of iPhone.Based on the dual-antenna design of iPhone 4, Apple said that iPhone 4S can intelligently switch back and forth between them to send and receive, improving the reception and throughput on the device. The iPhone 4S is also a world phone, which means both GSM and CDMA network customers can roam internationally on GSM networks on a single phone. It also supports HSPA+, a 4G mobile technology that allows for data transmission speeds up to 42 Mbps.Another important feature is the new voice control called Siri, an intelligent assistant that helps users get things done just by asking questions, such as call people, reminders, compose and dictate email, weather, stocks, search web and etc..For example, Siri understands users who are looking for a weather forecast when they ask questions like "Do I need an umbrella today," "What's the upcoming forecast," and "Is the weather going to get worse today."The iPhone 4S will run the latest version of Apple's mobile operating system iOS 5, which will be available as free update next Wednesday. The new iOS 5 has more than 200 new features, such as a deep Twitter integration, Notification Center and iMessage, a new messaging service.The latest smartphone also comes with the launch of iCloud, Apple's cloud computing service which automatically and wirelessly store users' content and push it to all Apple devices from mobile devices and music players to desktops and notebooks. Apple will launch iCloud next Wednesday."iPhone 4S plus iOS 5 plus iCloud is a breakthrough combination that makes the iPhone 4S the best iPhone ever," said Philip Schiller, Apple's senior vice president of Worldwide Product Marketing. "While our competitors try to imitate iPhone with a checklist of features, only iPhone can deliver these breakthrough innovations that work seamlessly together," said Schiller, who led the iPhone 4S introduction at the Tuesday's event.The new iPhone 4S will start at 199 U.S. dollars with a storage capacity of 16 GB and 399 dollars for the 64 GB model. The pre- orders begin on Friday and the phone will ship next Friday. Apple said that iPhone will be in 70 countries and regions, on 100 carriers when the roll out is done. In the United States, along with AT&T and Verizon, iPhone 4S will also come to Sprint, the third-largest mobile-phone carrier in the country.

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.
