LOS ANGELES, April 27 (Xinhua) -- Air pollution poses a threat to the health of about 154 million Americans -- or more than half of the U.S. population, the American Lung Association (ALA) said on Wednesday.The air is so polluted in some areas that it is often dangerous to breathe, the ALA said in its annual report on air quality across the United States.About 48 percent of U.S. residents live in counties where smog (ozone) is too high, 20 percent live in areas where there are too many short-term spikes in pollution and six percent live in areas with harmful year-round soot (particle pollution), said the report.About 17 million Americans live in areas afflicted by all three air pollution hazards, the report noted.The report listed California as the most polluted state, where people are breathing some of the worst air.Compared with other states, California has more polluted places, including Los Angeles, Long Beach, Riverside, Bakersfield and Fresno, the report said.Honolulu in Hawaii and Santa Fe-Espanola in New Mexico are the only two cities in the nation that had no days in which smog and soot levels reached unhealthy ranges, making them the cleanest cities in the nation, said the report.Research suggests air pollution threatens human health -- and not just the lungs.Small particles of pollution can lodge deep in the lungs, triggering an inflammatory process that, over time, can spread elsewhere in the body and damage blood vessels and the heart, according to Dr. Norman Edelman, the ALA's chief medical officer.On days in which smog levels spike, there's an increase in hospital admissions for respiratory illnesses, heart attacks and stroke in the two or three days following it, said Michael Jerrett, a professor of environmental health sciences at University of California, Berkeley's School of Public Health.In addition to posing both long-term and short-term risks, pollution can also contribute to low birth weights, diabetes, cardiovascular disease, heart attack, stroke and, ultimately, shorter life spans, he warned.

TOKYO, Feb. 6 (Xinhua) -- Japanese Prime Minister Naoto Kan said Sunday that Japan is ready to reconstruct relations with China in cultural, economic, political and other areas, the Jiji Press reported."This year marks the 100th anniversary of China's Revolution of 1911, and next year will be the 40th anniversary of the normalization of Sino-Japanese relations," said Kan at the first session of the "China-issue" advisory committee, organized by the Japanese government and attended by personages from economic, cultural and academic circles."On this special occasion," Kan said, "Japan is ready to rebuild relations with China in various areas such as culture, economic and politics."According to local media reports, participants at the meeting put forward suggestions such as "China is a promising market in the economic area, and ties with China are thus of great importance" and "people-to-people exchanges need to be promoted in areas of culture, sports and arts."The committee is scheduled to submit the final advisory report to the government in mid-April.

BEIJING, Feb. 5 (Xinhua) - Beijing has seen the arrival of 660,000 tourists during the first three days of the Spring Festival holiday, from Feb. 2 to 4, said Beijing Municipal Bureau of Tourism officials late Friday.The tourism data was collected at the city' s 22 scenic spots.On February 4, official statistics showed that 40,000 tourists swarmed into the Palace Museum, repeating the number from last year' s national holiday, while about 14,500 ski-lovers enjoyed their time at 14 ski resorts in Beijing on the same day.Not only scenic spots, tourists also gravitated to some cultural venues in Beijing.The Beijing-based National Art Museum of China holds an exhibition on "donated masterpieces over the past 50 years (since its completion in 1952)" from Jan. 27 to Feb. 26 and spectators can visit, free of charge, during the Spring Festival holiday (between Feb. 3 and 9).On February 5, visitors queued up in a 200-meter long line waiting for check-in to the museum around 10 a.m.Wang Xiumei, 86, decided to visit the museum with her daughter ten days before."My husband and I were crazy about traditional Chinese paintings decades ago, I have to see some masterpieces today, rather than hearing about them later." Wang said.Hundreds of the nation' s art works are displayed in a dozen halls in the five-storey exhibition area, including oil paintings, ink paintings, wood block prints, shadow puppets, paper cuttings, clay sculptures and embroideries."I changed my mind and got off the bus on my way to a temple fair. My children and I want to see some elegant art works, as opposed to eating and playing during Spring Festival as before," said another citizen named Lu Hongmao.Big cities like Beijing, Shanghai and Guangzhou opened their sports venues to the public during the Spring Festival holiday.

WASHINGTON, April 3 (Xinhua) -- In the largest study of its kind, researchers from a consortium led by the University of Pennsylvania School of Medicine, the University of Miami, and the Boston University School of Medicine, identified four new genes linked to Alzheimer's disease. The findings appeared Sunday in the current issue of Nature Genetics.Each gene individually adds to the risk of having this common form of dementia later in life. These new genes offer a portal into what causes Alzheimer's disease and is a major advance in the field.The study, conducted by the Alzheimer's Disease Genetics Consortium, reports genetic analysis of more than 11,000 people with Alzheimer's disease and a nearly equal number of elderly people who have no symptoms of dementia. Three other consortia contributed confirming data from additional people, bringing the total number of people analyzed to over 54,000. The consortium also contributed to the identification of a fifth gene reported by other groups of investigators from the United States, the United Kingdom, France, and other European countries.The study is the result of a large collaborative effort with investigators from 44 universities and research institutions in the United States, led by Gerard Schellenberg at University of Pennsylvania."This is the culmination of years of work on Alzheimer's disease by a large number of scientists, yet it is just the beginning in defining how genes influence memory and intellectual function as we age. We are all tremendously excited by our progress so far, but much remains to be done, both in understanding the genetics and in defining how these genes influence the disease process," Schellenberg said.Until recently, only four genes associated with late-onset Alzheimer's have been confirmed, with the gene for apolipoprotein E-e4, APOE-e4, having the largest effect on risk. The Nature Genetics studies add another four -- MS4A, CD2AP, CD33, and EPHA1 -- and contribute to identifying and confirming two other genes, BIN1 and ABCA7, thereby doubling the number of genes known to contribute Alzheimer's disease.

BEIJING, Feb. 15 (Xinhua) -- China's consumer inflation accelerated in January on surging food prices, adding pressure for the government to tackle escalating inflation amid the nation's spreading winter drought.The consumer price index (CPI), a main gauge of inflation, rose 4.9 percent in January year on year, the National Bureau of Statistics (NBS) announced Tuesday.The figure is 0.3 percentage points higher than that of December.Food prices soared 10.3 percent year on year.
