BEIJING, Oct. 13 (Xinhuanet) -- Himalayas may be one of the most potential regions to provide solar power in future, according to a new research by Japanese scientists quoted by media reports Thursday. Deserts are usually regarded as the hotbeds for capturing solar power, but some of the loftiest and coldest regions can receive more energy from the sun than some deserts, said Takashi Oozeki and Yutaka Genchi, authors of the research published in Environmental Science and Technology. To set up solar cells on Himalayas would be challenging. Transmission losses and snowfall should be taken into consideration, said the researchers with the National Institute of Industrial Science and Technology in Japan. Still, the Himalayan region is attractive, because there are large energy demands in the countries nearby."It is near regions with large future energy demands such as China and India," they said.Other cold regions that can receive solar power include Andes of South America and Antarctica, according to the study.

BEIJING, Jan. 21 (Xinhua) -- A locomotive producer in central China's Hunan province on Friday rolled out a low-cost magnetically levitated (maglev) train that is more environmental-friendly than conventional ones.The three-carriage train is designed to run at a maximum speed of 100 km per hour and carry 600 passengers, said Xu Zongxiang, general manager of Zhuzhou Electric Locomotive Co. Ltd. of China South Locomotive and Rolling Stock Corporation (CSR). Xu said the new train was much quieter than conventional ones. While a conventional train moves forward by using friction between its wheels and the railway tracks, the maglev train replaces wheels by electromagnets and levitates on the guideway. According to Xu, his company's has minimized the risk of the new maglev train derailing or overturning. "It's ideal for mass transportation, as it is quiet and environmental-friendly. Its manufacturing cost is about 75 percent of a conventional light-rail train," said Xu. The maglev train has a minimum turning radius of 50 meters and can easily run in residential communities or on hilly slopes. "It's an ideal public transport option for Chinese cities and major tourist destinations," said Xu. Railway transport specialist Liu Youmei, also an academician with Chinese Academy of Engineering, said the new train is green, economical and safe. "It can be used for public transport in populous areas and at scenic spots with fragile environments." Liu said China is one of a few countries that have applied maglev technology. Beijing is building a maglev route, the Daitai line (S1), which starts at its IT center in Haidian district, passes through Shijingshan district, and ends in Mentougou district on its western outskirts. The line will be operational next year.The eastern metropolitan of Shanghai runs the world's first commercial maglev system on a 30-km stretch between the downtown business district and Pudong airport. The German-made maglev went into operation on Dec. 31, 2002.

BEIJING, Oct. 11 (Xinhuanet) -- Scientists have discovered that blind optimism is related to brain's frontal lobes which are associated with processing errors, according to a British study published Monday in the journal Nature Neuroscience.Scientists at the University College of London scanned brains of volunteers who were asked to estimate their personal likelihood of involving in negative events, like a divorce or cancer,  before and after given the average probability of these events occurring.They found that the volunteers who estimated lower probability (or the more optimistic ones) than the given one raised their estimates a little bit later while those estimated higher probability altered their estimates much more.Through the brain scanner, scientists saw there was less activity in the volunteers' frontal regions when the information given was worse than expected while more activity when the information was better than expected. It suggested that the more optimistic people neglected the negative predictions."The more optimistic we are, the less likely we are to be influenced by negative information about the future," said Dr. Tali Sharot, lead author of the study. He added being optimistic clearly had some benefits, "but it can also mean that we are less likely to take precautionary action, such as practising safe sex or saving for retirement. So why don't we learn from cautionary information?"

NEW YORK, Dec. 27 (Xinhua) -- New York City Mayor Michael Bloomberg announced on Tuesday that babies born in the city in 2009 have the record high life expectancy of 80.6 years, an increase of nearly three years since 2000.The rate of 80.6 years is also above the U.S. national rate of 78.2 years. Life expectancy for 40-year-olds in New York increased by 2.5 years (79.5 to 82) from 2000 to 2009, outpacing the national trend of 1.2 year-increase for the same age group in the U.S. as a whole."If you have friends and relatives that you deeply care about, and they live elsewhere, on average if they move to New York City, they will live longer," said Mayor Michael Bloomberg at Lincoln Hospital in Bronx.Bloomberg contributed the life expectancy progress to the city' s health interventions, including its anti-smoking campaign and expanded testing and treatment for the HIV virus.Despite the progress, heart disease, cancer and influenza/ pneumonia continue to rank as the top three leading causes of death in New York City, followed by lung disease and diabetes.

BEIJING, Oct. 10 (Xinhua) -- The State Council, or China's cabinet, announced on Monday it will tax all resource products starting Nov. 1, extending the resource tax on domestic sales of crude oil and natural gas from some regions to the entire country.The list of taxable resources widened from crude oil and natural gas to coal, rare earth, salt and metal from Nov. 1, according to the country's revised resource tax regulations.The expansion of the resource tax is part of China's efforts to encourage energy conservancy and limit environmental damage.Sales of crude oil and natural gas nationwide will be taxed at a rate between five and 10 percent of their sales value, according to the revised regulations.The regulations impose a sales tax ranging from eight (1.25 U.S. dollars) to 20 yuan per metric ton on coking coal and from 0.40 to 60 yuan per metric ton on rare earth ore.Taxes on other types of coal stood unchanged at 0.30 to five yuan per metric ton.The tax rate for other non-ferrous metals is set between 0.4 to 30 yuan per metric ton. Ferrous metals will be taxed at two to 30 yuan per metric ton.Taxes on precious non-metallic ore will be between 0.5 to 20 yuan per kg or per carat, while taxes on cheap non-metallic ore are set between 0.5to 20 yuan per metric or per cubic meter.China's current resource tax is levied based on production volume instead of sales value, thus preventing the government from benefiting from energy and commodity price increases.Nonetheless, energy giants and mining companies such as PetroChina and Sinopec have enjoyed large profit margins on the sale of resources under the current tax scheme.A resource tax on oil and natural gas was introduced at a rate of five percent in northwest China's Xinjiang Uygur Autonomous Region on June 1, 2010 before being extended to 11 other provinces in December last year.
