SEOUL, Nov. 8 (Xinhua) -- Samsung Electronics, the world's largest flat screen TV vendor, said Tuesday that it has suspended its plan to develop active shutter three-dimensional (3D) TVs with RealD, the U.S.-based 3D technology supplier."Samsung has decided to focus on our own initiatives of 3D technology, and continues to research and develop next-generation 3D display technologies, including a glasses-free 3D solution for the home," the tech firm said in an e-mailed statement.The active shutter 3D technology drew public attention after Samsung reached a deal with RealD earlier this year to jointly develop such technology, aiming to unveil 3D TVs based on the technology early next year.The active shutter is a next generation 3D technology that incorporates merits from both shutter-glass (SG) technology, which Samsung adopted, and film patterned retarder (FPR) technology, which LG introduced in December last year.The SG technology has been touted as better picture quality and deeper 3D images, but the eyewear is heavier because it requires batteries and chips to work. The active shutter 3D technology moved its function of 3D image creation from eyewear to flat panel, making the eyewear lighter.Despite the upgraded technology and its convenience, Samsung decided to focus on its existing SG technology as the global TV market is grappling with weak demand. The penetration rate, which gauges the ratio of 3D sets against the total flat screen TVs, was expected to rise to 9.9 percent by year-end from the 3 percent a year earlier, according to Woori Investment & Securities, a local securities firm.

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. 24 (Xinhuanet) -- There is no evidence to prove that using a cell phone can increase the risks of brain cancer, suggested a lastest study by Danish researchers.To arrive at the result, the researchers examined the health records from 1990 to 2007 for 358,403 Danish cell phone plan subscribers.They found that among people using cell phones for as long as 13 years or more, the cancer risks were almost the same as for non-subscribers.The finding, published in the British Medical Journal last week, alleviated the fear among the world's 5 billion cell phone users.Five months ago, a statement from the World Health Organization's International Agency for Research on Cancer (IARC) sparked fear in cell phone users around the world because it said that cell phone use might cause brain cancer.However, the finding could not rule out the risk of brain cancer triggered by heavy use of cell phones, admitted Patrizia Frei of the Danish Cancer Society's Institute of Cancer Epidemiology, lead author of the study.Frei added, cited by CNN, "There are still some open questions, about greater amounts of use, and about the effects on children."The IARC did not give formal response to the study, but it offered some ways for cell phone consumers to reduce possible risks months ago.Texting and using hands-free sets for voice calls lower exposure to potentially harmful radiation, compared to device-to-ear voice calls, by at least 10-fold, IARC stated, reported by the New York Daily News.

SHANGHAI, Dec. 9 (Xinhua) -- China's homegrown C919 large passenger plane has finished its preliminary development review and entered the development phase, a senior executive of Commercial Aircraft Corporation of China Ltd. (COMAC) in Shanghai said Friday.An expert team of the C919 project has approved the overall preliminary development review (PDR) of the passenger jet, said Jin Zhuanglong, president of the Shanghai-based COMAC.It is expected that the manufacturing process for the components of the prototype will begin by the end of 2011.COMAC signed a deal to sell 20 C919 large passenger planes to China Aircraft Leasing Company Limited (CALC) on Thursday.Up to now, the users of C919 large passenger planes have reached 10 and total orders amount to 215 units.COMAC said earlier it would develop both 168-seat and 156-seat models of the jet, with more models to be developed in the future.It also said that test flights for the single-aisle C919 were scheduled for 2014, and delivery is slated for 2016.

WASHINGTON, Dec. 5 (Xinhua) -- Young women may reduce their risk of developing cardiovascular disease simply by eating more fish rich in omega-3 fatty acids, researchers reported Monday in Hypertension: Journal of the American Heart Association.In the first population-based study in Danish women of childbearing age, those who rarely or never ate fish had 50 percent more cardiovascular problems over eight years than those who ate fish regularly. Compared to women who ate fish high in omega-3 weekly, the risk was 90 percent higher for those who rarely or never ate fish.About 49,000 women, 15-49 years old, median age of just under 30 years in early pregnancy -- were interviewed by telephone or answered food frequency questionnaires about how much, what types and how often they ate fish, as well as lifestyle and family history questions.Researchers recorded 577 cardiovascular events during the eight- year period, including five cardiovascular deaths in women without any prior diagnosis of the disease. In all, 328 events were due to hypertensive disease, 146 from cerebrovascular disease, and 103 from ischemic heart disease. Inpatient and outpatient admission for cardiovascular disease was much more common among women who reported eating little or no fish. In three different assessments over a 30-week period, women who never ate fish had a three-fold higher disease risk compared to women who ate fish every week."To our knowledge this is the first study of this size to focus exclusively on women of childbearing age," said Marin Strom, lead researcher and post doctoral fellow at the Center for Fetal Programming, at Statens Serum Institute in Copenhagen, Denmark. " We saw a strong association with cardiovascular disease in the women who were still in their late 30's."Fish oil contains long chain omega-3 polyunsaturated fatty acids, which are believed to protect against heart and vascular disease. Few women in the study took fish oil supplements, so these were excluded from the analyses and the results were based on the dietary intake of omega-3 fatty acids, not intake from supplements.The most common fish consumed by women in the study were cod, salmon, herring, and mackerel."Our study shows that for younger women, eating fish is very important for overall health, and even though we found cardio- protective effects at relatively modest dietary levels, higher levels may yield additional benefits," Strom said.
