BEIJING, Nov. 22 (Xinhuanet) -- Global AIDS deaths and new HIV infections have each dropped 21 percent since the peak of the AIDS pandemic in 1997, according to a UN report released Monday.One major factor responsible for the result is that life-saving HIV treatments have become more popular and got to 1.35 million more people in 2010 than in 2009.In middle-income and underdeveloped nations, these treatments have saved 2.5 million lives since 1995."We have seen a massive scale-up in access to HIV treatment, which has had a dramatic effect on the lives of people everywhere," said Michel Sidibe, executive director of the U.N. AIDS program.However, 53 percent of people who need HIV/AIDS treatments -- about 7.6 million people -- cannot get them, which accounted for 1.8 million AIDS deaths in 2010.There are now 34 million people living with HIV. And just in last year there were 2.7 million new infections.The decline in deaths and new infections means the AIDS pandemic is at a turning point, the UNAIDS report argues, adding smart investment can save millions of future deaths.

BEIJING, Jan. 6 (Xinhua) -- Beijing will offer residents 20,000 rental bikes this year to ease the city's notorious traffic jams, according to authorities with the Beijing Municipal Commission of Development and Reform.Five hundred rental kiosks will be set up around the city to offer residents over 20,000 rental bikes, the commission said.Beijing has also proposed creating new bike lanes in some areas, including main streets, historical and cultural conservation areas and some major business districts, from 2011 to 2015, according to the commission.The capital city currently has about 5 million vehicles on its roads, leading to serious traffic congestion that frustrates the city's residents on a daily basis."A lack of bike lanes is the reason why I refuse to ride a bike. Bikes and vehicles are using the same lanes, and that frightens me and makes me feel unsafe," said Beijing resident Song Tao.People often park cars on the city's existing bike lanes, pushing cyclists onto the vehicles' lanes, said Song.To ease traffic congestion, Beijing has made various efforts to encourage people to opt for modes of public transportation.On Dec. 31, Beijing opened three new subway lines, bringing the number of subway lines in Beijing to 15, with a total length of 372 kilometers, said Beijing Metro Spokesman Jia Peng.Beijing will open four more subway lines in 2012, according to information released at a rail transit construction mobilization conference.Amid other measures to ease traffic in 2011, city authorities decided to allow only 240,000 vehicles to be registered annually, slashing the new car registrations by two-thirds from the 2010 level.Meanwhile, vehicles are banned from roads one day each week according to license plate numbers.

WASHINGTON, Jan. 16 (Xinhua) -- A new study examining weather patterns around the worldwide pandemics of influenza, which caused widespread death and illness in 1918, 1957, 1968 and 2009, finds that each of them was preceded by La Nina conditions in the equatorial Pacific. The study findings are published online Monday in the Proceedings of the National Academy of Science.The study's authors -- Jeffrey Shaman of Columbia University's Mailman School of Public Health and Marc Lipsitch of the Harvard School of Public Health -- note that the La Nina pattern is known to alter the migratory patterns of birds, which are thought to be a primary reservoir of human influenza. The scientists theorize that altered migration patterns promote the development of dangerous new strains of influenza.To examine the relationship between weather patterns and influenza pandemics, the researchers studied records of ocean temperatures in the equatorial Pacific in the fall and winter before the four most recent flu pandemics emerged. They found that all four pandemics were preceded by below-normal sea surface temperatures -- consistent with the La Nina phase of the El Nino- Southern Oscillation.The authors cite other research showing that the La Nina pattern alters the migration, stopover time, fitness and interspecies mixing of migratory birds. These conditions could favor the kind of gene swapping or genetic reassortment that creates novel and therefore potentially more variations of the influenza virus."We know that pandemics arise from dramatic changes in the influenza genome. Our hypothesis is that La Nina sets the stage for these changes by reshuffling the mixing patterns of migratory birds, which are a major reservoir for influenza," says Shaman.Changes in migration not only alter the pattern of contact among bird species, they could also change the ways that birds come into contact with domestic animals like pigs. Gene-swapping between avian and pig influenza viruses was a factor in the 2009 swine flu pandemic.

BEIJING, Oct. 20 (Xinhuanet) -- A Teenager's intelligence is not fixed as usually thought. Instead, it can go through swings in a few years, according to a British study reported online in Nature.Teenagers' IQ can rise or fall 20 points over time, researchers from Wellcome Trust Centre for Neuroimaging of Kings College, showed in their study.IQ (short for "intelligent quotient") is an gauge of mental capability measured through a series of standardized tests of language skill, spatial ability, arithmetic, memory and reasoning.To get the findings, Cathy Price, senior researcher of the study, and her colleagues tested 33 British teenagers between the ages of 12 to 16 in 2004, who had average IQ scores around 100. Then the teenagers were retested four years later.The researchers found the volunteers' IQ scores went up and down over the four years, with some teenager's scores rising by as many as 20 points, and others' dropping by the same points."That is quite astounding," cheered psychologist Robert Plomin from the same university but not involved in the study. Dr. Price and her colleagues don't know the causes of such fluctuations in the scores they tested, but speculate that learning experiences might account the changes, reported by the Wall Street Journal Today. "We have to be careful not to write off poorer performers at an early stage when in fact their IQ may improve significantly given a few more years," stated Dr. Price cited by the Huffington Post.

BEIJING, Jan. 23 (Xinhua) -- Nearly 200,000 local residents and tourists visited parks in Beijing on Monday as a series of celebrations were hosted to mark the first day of the Chinese lunar New Year, the city's park administration said.Festive activities kicked off at Beijing's famous parks, including the Temple of Heaven, the Summer Palace, and the Beihai Park, on Monday to welcome the Year of the Dragon, said Chen Zhiqiang, spokesman for the Beijing Municipal Administration Center of Parks.At the Temple of Heaven, 320 costumed performers on Monday staged a show presenting the royal heaven worship ceremony in the Qing Dynasty (1644-1911).In the one-hour ceremony, thousands of visitors watched as the royal parade marched toward the altar where the "emperor" held a ritual to pray for peace and good harvest in the coming year.At the Summer Palace, the ancient royal garden, a traditional fair opened to public with old-fashioned shops and stands selling items and snacks popular in the old days.The Chinese New Year, which begins on Monday this year, is an important occasion for family dinners, fireworks, and a trip to temple fairs.To cope with the increase in visitors, authorities in Beijing said they have deployed seven police choppers and 910,000 order-maintaining personnel across the city to prevent the breakout of fires and stampedes.
