SAN FRANCISCO, April 8 (Xinhua) -- YouTube on Friday launched YouTube Live, a homepage for live content on the site and a new live-streaming platform.As part of the service, the world's largest video-sharing website introduced a new browse page, www.youtube.com/live, where users can view live events and add upcoming events to their calendars.YouTube said it would gradually roll out a live streaming beta platform, which will allow certain YouTube partners with accounts to stream live content on the website.The new service will "integrate live streaming capabilities and discovery tools directly into the YouTube platform for the first time," YouTube said in a blog post.U.S. media recently reported that YouTube is planning a major overhaul and is negotiating with Hollywood and music producers for materials to offer on a lineup of new channels, with the aim to compete with broadcast and cable television.

ZHENGZHOU, Feb. 16 (Xinhua) -- China's Yellow River catchment authority has launched emergency measures to restrict industrial water usage and to release reservoir water for wheat crops in the face of a worsening drought.The Yellow River Flood Control and Drought Relief Headquarters raised on Wednesday its drought alert from yellow to orange, the second-highest level, indicating the area is facing the worst drought in up to half a century.The headquarters ordered all authorities along the catchment area to initiate an emergency response to ensure water supplies for people and livestock, and to restrict industrial water consumption.The drought, which has plagued the middle and lower reaches of the Yellow River since October last year, was likely to affect more than 40 percent of crops in the area, said a headquarters spokesman.Light to moderate snowfall brought some relief to the wheat farmers in the region over the weekend, but not enough to end the drought. Most regions along the Yellow River received precipitation of less than 10 mm.Thanks to the recent rise in temperatures, ice covering 120-km of the Yellow river has melted, offering more water for irrigation and other water uses.The headquarters' statistics show that water channeled from the Yellow River reached 228 cubic meters per second at 8 a.m. Tuesday, and supplied the drought-plagued Shandong Province, Tianjin Municipality and Hebei Province.The headquarters had released more water from reservoirs along the catchment to help with the irrigation of winter wheat crops, said the spokesman.The Chinese government on Friday announced plans to dig 1,350 wells in eight major wheat-growing provinces to help ease the drought that is threatening grain harvests.

BEIJING, April 14 (Xinhuanet) -- Computer sales declined in the first three months of this year for the first time since 2009 worldwide.PC sales fell 1.1 percent in the first quarter to 84.3 million worldwide, according to tech research firm Gartner Wednesday, well short of its forecast for 3 percent growth.The dip was the first since the second quarter of 2009, when most of the world was still in the grip of economic turmoil."Although the first quarter is traditionally a slow one for PC sales, these shipment results indicate potential sluggishness, not just a normal seasonal slowdown," said Gartner, in a statement.Consumers select IT products at an IT fair named "Sham Shui Po computer festival" in Hong Kong, south China, Feb. 15, 2011. The eight-day IT fair kicked off here Monday. Some 600,000 people are predicted to visit the fair.Weak demand for consumer PCs was the biggest drag on the market, according to Gartner principal analyst Mikako Kitagawa."Low prices for consumer PCs, which had long stimulated growth, no longer attracted buyers," Kitagawa said."Instead, consumers turned their attention to media tablets and other consumer electronics."After Apple's second-generation iPad was released in February, many consumers either switched allegiances or simply held back from buying PCs, according to the analyst.Japan was a particularly weak spot, with PC sales falling 13 percent in the quarter, as people focused on getting back to normal after the March 11 earthquake and tsunami rather than spending money on new technology.

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. 3 (Xinhua) -- Chinese Foreign Ministry said here Thursday that almost all Chinese travellers stranded in Egypt had returned home by planes sent by the government.A total of 1,848 Chinese, including those from Hong Kong, Macao and Taiwan, had been flown back by Thursday afternoon, the ministry said in a statement.The Chinese government has organized eight flights from four Chinese airline companies to Egypt since Jan. 31.The last two planes, belonging to China Eastern Airlines, returned to Beijing from Egypt Thursday, bringing back a total of 431 Chinese citizens, according to the ministry.
