BEIJING, Sept. 6 (Xinhuanet) -- A short-term memory loss may suggest the Alzheimer's disease, according to a new study made by Spanish researchers.The finding was published on Monday, in Archives of General Psychiatry, an American Medical Association journal.The researchers gathered data of 116 people with mild cognitive impairment (MCI) who developed Alzheimer's disease within two years, 204 patients with the condition who didn't develop Alzheimer's and 197 people with no cognitive problems.Mild cognitive impairment is usually marked by difficulties with short-term memory, such as losing your train of thought repeatedly or having trouble remembering what you did yesterday, according to the study.After assessing them by biomarker tests and cognitive measures, the researcher found the cognitive markers can forecast the variance."Remarkably, they accounted for nearly 50% of the predictive variance," said Dr. Gomar of Centro de Investigation Biomedica en Red de Salud Mental, Barcelona, who led the research.Mild cognitive impairment at the start of the study was a stronger predictor of Alzheimer's than most biomarkers, the researchers concluded.

BONN, Germany, June 17 (Xinhua) -- The latest United Nations (UN) climate talks ended here on Friday with no surprise -- some " technical issues" saw some progress, as delegates usually said, while major disagreements remained.The two-week UN climate negotiations have made "clear advances" on such issues as extending carbon trading mechanisms, climate fund management and slowing deforestation, Christiana Figueres, UN Framework Convention on Climate Change (UNFCCC) executive secretary, said at a closing press conference.Figueres said delegates from 183 countries stepped forward with a technology mechanism to boost global green technology sharing. The mechanism will include a Climate Technology Center and Network to establish a worldwide clean technology stakeholder community.As for the implementation of a comprehensive package of the Cancun summit last year, this Bonn session has "paved the way" for progress at the next UN ministerial-level climate conference, which is to be held in Durban, South Africa from Nov. 28 to Dec. 9, Figueres said."Strong convergence has emerged on how the Adaptation Committee will be governed, what its composition will be and what its specific role will be," she said. "This progress means that the Committee could be fully operationalized at Durban."The UN climate chief stressed that governments, business circles and civil society cannot solve issues related to climate change "in one meeting," and climate talks are "the most important " negotiations the world has ever seen."The Bonn meeting is practical, focusing on concrete issues. In general, the negotiating process is moving forward step by step and on the right track," Su Wei, China's chief negotiator, told Xinhua on Friday."Despite setbacks and reversals, parties are taking climate change seriously and are willing to promote the negotiations under the Bali Roadmap," he said. "In the past two weeks, contact groups are busy making informal consultations on various topics.""Admittedly, in some key areas, there is a gap among parties," Su said.During the meeting, many delegates and observers have complained that the pace of negotiation was unbearably slow, especially against the backdrop of a new warning from the International Energy Agency, which said the global energy-related carbon emissions rose to a record high in 2010 despite decade-long efforts on curbs.Experts said one of the main hurdles in current talks was still the old topic -- the fate of the Kyoto Protocol, the sole legally- binding pact on industrial countries' emission cuts set to expire at the end of 2012.The protocol, which binds 37 rich countries, has been crippled since Cancun, as Japan, Canada and Russia have clearly stated they would not extend the pact's second commitment period after 2012.The United States, which never ratified the treaty, said it would not accept any legal deal unless other major economies have similar emission constraints.The European Union (EU), the last major bloc that is open to the renewing of the Kyoto Protocol, said its supportive attitude should not be taken for granted. The EU said it would not unilaterally step up efforts on combating climate change if other nations are not willing to do the same.Meanwhile, developing countries insisted that the updating of the Kyoto Protocol remains "the very core issue" of current talks, asking rich nations to shoulder their historical responsibilities and preserve the pact as a major legally-binding instrument to tackle climate change.The Group of 77 and China, representing over 130 developing nations, have said that the renewal of the Protocol should be the priority for Durban.On Friday, Figueres said that "resolving the future of the Kyoto Protocol is an essential task this year and will require high-level political guidance.""By Durban, governments need to come forward with options that will be acceptable to all parties," she said, adding that high- level contacts are necessary to break the ice.She told reporters that environment ministers are due to meet in Berlin from July 3 to 4, known as a continuation of last year's ministerial-level informal talks held in the town of Petersburg near Bonn. Moreover, world leaders are due to discuss climate change on the sidelines of the UN General Assembly in September.Before the Durban summit, delegates have agreed to hold an additional round of climate talks in late September or early October, Figueres revealed.

WELLINGTON, Sept. 27 (Xinhua) -- New Zealand and Japanese scientists are teaming up to develop healthier foods under two government-funded "functional foods" projects.One project, to be led by New Zealand's Massey University, will work with New Zealand food companies to create and develop a functional food with specific health enhancing effects for menopausal women, New Zealand Science and Innovation Minister Wayne Mapp announced Tuesday.The other project, to be led in New Zealand by Plant and Food Research, would use mass spectrometry to develop a "metabolic atlas" of the chemical composition of allium vegetables, such as onions and garlic, which the horticultural industry could use to develop new food products with health benefits.Mapp said the two research projects would be awarded a total of 1 million NZ dollars (782,000 U.S. dollars) in funding to strengthen collaborative research relationships between New Zealand and Japan, Mapp said."These research projects have strong commercial potential, including through the Japanese market, and so have the potential to benefit our economy," said Mapp."The government is committed to building and strengthening research relationships with other countries that will achieve world-class scientific results and lead to new innovative technologies."The two projects awarded funding under Ministry of Science and Innovation's Japan Science and Technology Agency (JST) funding round focus on functional foods. The ministry and Japan each fund half the cost of each research project awarded funding.

MOSCOW, Sept. 13 (Xinhua) -- Russian federal space agency -- Roscosmos -- has announced that it would launch four more spacecraft in the forthcoming four months, including two Soyus manned spacecraft to the International Space Station (ISS).In accordance with the work schedule of Roscosmos, two cargo spaceships -- of the "Progress" type -- will be launched on Oct.30, 2011 and on Jan.26, 2012, while the two manned spacecraft will be blast off on Nov.12 and Dec.20.Roscosmos said on Tuesday it had been conducting consultations with NASA over updated plans of the upcoming expeditions to the ISS.According to Roscosmos, the new launch schedule has been drafted on the basis of an investigation into an abortive launch of a cargo spaceship on Aug. 24, when the Progress M-12M cargo spaceship failed to reach the orbit due to a rocket malfunction. Russia announced on the same day to delay its future launches of manned spaceship to ISS.After the retirement of the U.S. space shuttle fleet, Russia's Soyuz spacecraft has become the only way for astronauts to reach the ISS until at least the middle of this decade.

BEIJING, Sept. 2 (Xinhuanet) -- The amount of space junk orbiting the Earth could cause fatal leaks in spaceships or destroy valuable satellites, according to a report released by the U.S. National Research Council.Computer models have shown that the number of orbital debris "has reached a tipping point, with enough currently in orbit to continually collide and create even more debris, raising the risk of spacecraft failures," the Research Council said Thursday.So far, there are 22,000 pieces of debris large enough to track from the ground, but smaller objects could still cause serious damage.New international regulations are needed to limit space junk.And more researches should be done to test the possible use of launching magnetic nets or giant umbrellas to push the debris further towards the Earth where it would burn up, or into a higher but safer orbit.
