SAN FRANCISCO, Nov. 7 (Xinhua) -- Google on Monday added a highly-anticipated service to its Google+ social network, allowing businesses and brands to set up their own pages on the site.Named "Google+ Page," the service is a further challenge to its rival Facebook's fan pages, which has become a major promotion strategy for many business brands over the past several years.Unlike Facebook, Google will not charge businesses and organizations for using the scheme, and will not put ads on the pages. The service is expected to enhance the tech giant's other businesses like search and mobile advertising.Some big brand names, such as Burberry, the Barcelona football club and the Muppets, have already set up their pages.Google noted it will not pass on personal data.In addition to big brands, Google also wants small businesses that have or do not have their own websites to use Google+ Pages as their default presences.According to a report by Ad Age Digital, Google+ Pages will soon be location-aware, allowing local businesses to send offers and deals to mobile phones.According to Google, more than 40 million people have opened an account with its social network, which was launched in June. Although the network is growing very quickly, some analysts said it still has a long way to go to become a major threat to Facebook, which has more than 800 million users.

BEIJING, Oct. 21 (Xinhua) -- China's State Councilon Thursday called ordered improved, innovative administration in environmental protection, according to a statement.In a statement published on the central government's website, the State Council listed a series of guidelines on environment-related issues, saying that it will step efforts to address prominent environmental problems that affect people's lives and sustainable development.The statement ordered strictly implementing environmental impact assessment, vigoroulsy developing environmental protection industry, and ensuring nuclear and radioactive safety.It called for implementing economic policies beneficial to environmental protection.The statement also ordered local governments at all levels to attach more importance to environmental protection, noting ecological conditions should be considered in evaluating the performance of local leaders.

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.

WASHINGTON, Nov. 22 (Xinhua) -- Long-term coffee consumption may be associated with a reduced risk for endometrial cancer, according to a study published online Tuesday in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.Edward Giovannucci, professor of nutrition and epidemiology at the Harvard School of Public Health, said that coffee is emerging as a protective agent in cancers that are linked to obesity, estrogen and insulin."Coffee has already been shown to be protective against diabetes due to its effect on insulin," said Giovannucci, a senior researcher on the study. "So we hypothesized that we'd see a reduction in some cancers as well."The researchers observed cumulative coffee intake in relation to endometrial cancer in 67,470 women who enrolled in the Nurses' Health Study. During the course of 26 years of follow-up, researchers documented 672 cases of endometrial cancer.Drinking more than four cups of coffee per day was linked with a 25 percent reduced risk for endometrial cancer. Drinking between two and three cups per day was linked with a seven percent reduced risk.A similar link was seen in decaffeinated coffee, where drinking more than two cups per day was linked with a 22 percent reduced risk for endometrial cancer.Giovannucci said that he hopes this study will lead to further inquiries about the effect of coffee on cancer because in this and similar studies, coffee intake is self-selected and not randomized.

HAIFA, Israel, Oct. 5 (Xinhua) -- "It's a big day, a celebration shared by Israel, science and the entire world," Israeli researcher Daniel Shechtman, who won the 2011 Nobel Prize in chemistry, said here at a press conference at the Technion- Israel Institute of Technology.Shechtman, 70, has spent the past five decades at Technion. He is also an associate at the Ames Laboratory of the U.S. Department of Energy and has lectured at universities abroad."Thousands of scientists are currently researching the subject I developed and I'm sure that all of them view the prize as their accomplishment too," he told Xinhua, adding that, "Science (in general) wouldn't be here and be as prosperous and intricate as it is if not for the work of thousands of others around the world."The Swedish Royal Academy of Sciences on Wednesday announced Shechtman as the winner of this year's Nobel chemistry prize for his cutting-edge research on quasicrystals, a type of atom form that for decades was considered impossible by the global scientific community.The award panel explained that Shechtman's work, launched in early 1980s, has revolutionized the perception of solid matter.His work forced crstyallographers to revamp their basic conception that atoms inside crystals only have repeating and symmetrical patterns.Shechtman is the 10th Israeli scientist to win the Nobel Prize and the fourth to win the prize in chemistry.Ada Yonat, a researcher at the Weizmann Institute near Tel Aviv, received the chemistry prize in 2009.The announcement from Stockholm captured headlines in Israel, drawing praise from the country's leadership, who said Shechtman's achievement is a testament to the Jewish state's stature as a technological powerhouse.Israeli Prime Minister Benjamin Netanyahu said the winning of the Nobel Prize "expresses our people's intellect.""Every Israeli citizen is happy today and every Jew in the world is proud," a statement issued by Netanyahu's office quoted him as telling the scientist in a telephone call.Israeli President Shimon Peres, who is also a Nobel laureate, later called to congratulate Shechtman."You demonstrate that a thinking person who is hardworking and brave can make groundbreaking scientific discoveries," he said.
