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.

SHIJIAZHUANG, Oct. 16 (Xinhua) -- Chinese archaeologists said Sunday that they have found evidence of the cultivation of glutinous millet in the northern province of Hebei that could date back to 10,000 years, the earliest evidence of people growing the crop in the world.Lab results showed that remains of glutinous millet found at archaeological sites in Cishan Village in the city of Wu'an were harvested during the Neolithic Era between 8,700 to 10,000 years ago, scientists with the Institute of Geology and Geophysics of China Academy of Sciences (IGGCAS) said at a cultural festival held in Wu'an on Sunday.This means Cishan was the birthplace of the crop, archaeologists said.They have also found remains of foxtail millet in the pits, which could date back to between 8,700 and 7,500 years. This would be the earliest evidence of the crop's cultivation, which means that Cishan was the birthplace of foxtail millet, too, said Lu Houyuan, an IGGCAS scientist.Cultivating small-seeded dry crops was more prevalent than cultivating rice in prehistoric times, especially in China's semi-arid northern regions, Lu said.A total of 50,000 kilograms of grains have been stored in 88 pits for thousands of years at the Cishan Site, a Neolithic site discovered in 1972.In addition to grain remnants, pottery, stone tools, animal bones and bone artifacts have also been excavated from the site, which archaeologists believe will help their research in the emergence of agriculture in China.

WASHINGTON, Dec. 1 (Xinhua) -- U.S. President Barack Obama announced Thursday that his administration is committing an addition 50 million U.S. dollars in funding for domestic HIV/AIDS treatment and care.Obama also set a new target of helping six million people in countries hardest hit by the HIV virus get access to life-saving antiretroviral drugs by the end of 2013, increasing the original U. S. goal by two million."We can beat this disease,"' Obama declared at a World AIDS Day event in Washington. Former Presidents George W. Bush and Bill Clinton also participated via satellite.Citing the success of the President's Emergency Plan for AIDS Relief program in providing antiretroviral treatment to people living with HIV/AIDS around the world, Obama admitted that new infections are still not going down in the United States."The rate of new infections may be going down elsewhere, but it 's not going down here in America,'' he said. "There are communities in this country being devastated still by this disease. When new infections among young, black, gay men increase by nearly 50 percent in three years, we need to do more to show them that their lives matter.''Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, also told Xinhua recently that in the United States, the AIDS epidemic has plateaued, but it is still at "unacceptably high" level.About 1.2 million Americans are living with HIV and only 28 percent of them have the infection under control, the U.S. Centers for Disease Control and Prevention reported this week."The fight is not over," Obama declared, but "the federal government can't do this alone." He called on state governments, pharmaceutical companies, and private foundations, to do their part to help Americans get access to all the life-saving treatments.Obama also appealed to global partners to step up their efforts to end AIDS, some 30 years after the epidemic first surfaced. "So on this World AIDS Day, here's my message to everyone out there. To the global community -- join us," he said.
