WASHINGTON, Dec. 21 (Xinhua) -- New research suggests that, in people who don't currently have memory problems, those with smaller regions of the brain's cortex may be more likely to develop symptoms consistent with very early Alzheimer's disease.The study was published Wednesday in the online issue of Neurology, the medical journal of the American Academy of Neurology.For the study, researchers used brain scans to measure the thickness of regions of the brain's cortex in 159 people free of dementia with an average age of 76. The brain regions were chosen based on prior studies showing that they shrink in patients with Alzheimer's dementia.Of the 159 people, 19 were classified as at high risk for having early Alzheimer's disease due to smaller size of particular regions known to be vulnerable to Alzheimer's in the brain's cortex, 116 were classified as average risk and 24 as low risk. At the beginning of the study, participants were also given tests that measured memory, problem solving and ability to plan and pay attention. The tests will go on over the next three yearsThe study found that 21 percent of those at high risk experienced cognitive decline during three years of follow-up after the MRI scan, compared to seven percent of those at average risk and none of those at low risk."Further research is needed on how using MRI scans to measure the size of different brain regions in combination with other tests may help identify people at the greatest risk of developing early Alzheimer's as early as possible," said study author Bradford Dickerson, of Massachusetts General Hospital in Boston and a member of the American Academy of Neurology.

BEIJING, Jan. 3 (Xinhua) -- A collection of China's nine white papers issued in 2011 has been published in both Chinese and English, according to a statement issued by the publisher on Tuesday.By giving a clear and precise illustration of China's policies, principles and progress in subjects like national defense, law, climate change and international trade, the white papers can help the world know about, and understand, China, the statement said.The white papers are titled, "China's National Defense in 2010," "China's Foreign Aid," "Sixty Years Since the Peaceful Liberation of Tibet," "China's Peaceful Development," "The Socialist System of Laws with Chinese Characteristics," "New Progress in Development-oriented Poverty Reduction Program for Rural China," "China's Policies and Actions for Addressing Climate Change (2011)," "China's Foreign Trade" and "China's Space Activities in 2011."The white papers were all published by the Information Office of the State Council on behalf of the Chinese government.The latest one on space activities was issued last Thursday.

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.

SAN FRANCISCO, Nov. 4 (Xinhua) -- With its popular iPhone series, Apple seized more than half of the profits generated by the top eight mobile phone manufacturers during the third quarter, said a monthly market analysis released on Friday.Apple generated a remarkable 52 percent of handset industry operating profits for the top eight OEMs (original equipment manufacturers) in the third quarter, up five percent over the same period of 2010, said Canaccord Genuity technology analyst Michael Walkley.The number was down from 57 percent in the second quarter, due to a drop in iPhone sales as customers held out for the upcoming iPhone 4S.A proud Apple customer shows off the new iPhone 4S he purchased at an Apple store in Munich, Germany.Apple's major rival in the mobile industry is Samsung. The two companies together represented 81 percent of the handset industry' s operating profits last quarter.Other major mobile phone manufacturers are Nokia, Motorola, Sony Ericsson, HTC, Research In Motion and LG.Calling it "an epic reversal of fortunes," Walkley noted that in 2007, Nokia had 67 percent of operating profits while Apple had just 4 percent. Compared with Apple's 52 percent of industry profits in the third quarter of 2011, Nokia has been relegated to its rival's former position with just 4 percent of operating profits.The analyst said he has conducted "channel checks" that show strong demand not only for the new iPhone 4S but also for the previous models of iPhone 4 and iPhone 3GS. He told technology news website AllthingsD that Apple is believed to be able to gain further value share in the December quarter and capture over 60 percent of industry profits.In a Bloomberg report on Friday, several technology analysts said the two-year-old iPhone 3GS, whose price has been slashed to zero if it is purchased with a contract, will become one of Apple' s big weapons in the coming holiday season against smartphones running Google's Android system.
