JERUSALEM, May 2 (Xinhua) -- Traditional farming may have found an ally on the Internet, via an Israeli "cloud-based" software system that enables farmers to get professional information and tips from colleagues worldwide.And IBM is interested in what they have to say.Agriculture Knowledge On-Line (AKOL) says its Internet-based system can aid global agriculture by utilizing the collective knowledge of kibbutzim (communal farms in Israel) and other agricultural experts, to offer small farmers personalized solutions to improve dairy output and crop production, and better prevent droughts.Owned by Kibbutz Bror Hayil in southern Israel, the software house has recently signed a cooperation and development agreement with IBM to manage access and technology issues."What we do here is like a bank of information and IBM provides the special tools for the end users," AKOL's CEO Roni Shani told Xinhua, "and you can do what we call 'agricultural market.'""For example, if someone in Australia needs advice on how to grow their crops better, they can just ask our advice or search through our database to find the best product for the country they 're growing the crops in," Shani said."Let's say someone in India, a small farmer, has a problem with their crop or chickens," Shani explained, noting that "it's usually very expensive and time consuming to get someone to come and check what is wrong."But, for a monthly fee, a basic subscription service enables the end user to access the software database, which allows "the farmer to just look at the pictures and pick the one that will explain what the disease or problem is and offer a solution, and if it is available in their country."AKOL claims about 1,000 customers over the globe."We just started developing it for use outside of the kibbutz with IBM's help," Shani said, "and we are developing it also in other parts of the world, like China. Right now we're cooperating with the Chinese government to help milk producers get the most out of their milking systems."Israel is one of the leading countries in milk production, with each cow yielding around 12,000 liters of milk a year on average. Two Chinese provinces plan to use AKOL's milking control system, in order to better manage their herds and equipment and increase milk production."And this is just the beginning," Shani explained, "because we are also working with other developing countries. This software will help millions of small farmers in rural or impoverished areas, that will be able to get advice and benefit from other farmers' experience on the spot and at a very affordable rate."

WASHINGTON, May 11 (Xinhua) -- Johns Hopkins University researchers have demonstrated that human liver cells derived from adult cells coaxed into an embryonic state can engraft and begin regenerating liver tissue in mice with chronic liver damage.The work, published Wednesday in the journal Science Translational Medicine, suggests that liver cells derived from so- called "induced-pluripotent stem cells (iPSCs)" could one day be used as an alternative to liver transplant in patients with serious liver diseases, bypassing long waiting lists for organs and concerns about immune system rejection of donated tissue."Our findings provide a foundation for producing functional liver cells for patients who suffer liver diseases and are in need of transplantation," says Yoon-Young Jang, assistant professor of oncology at the Johns Hopkins Kimmel Cancer Center. "iPSC-derived liver cells not only can be generated in large amounts, but also can be tailored to each patient, preventing immune-rejection problems associated with liver transplants from unmatched donors or embryonic stem cells." A microsopic view shows human embryonic stem cells in various stages of differentiation into liver cells in this photo taken at Stanford University and released by the California Institute for Regenerative Medicine, March 9, 2009iPSCs are made from adult cells that have been genetically reprogrammed to revert to an embryonic stem cell-like state, with the ability to transform into different cell types. Human iPSCs can be generated from various tissues, including skin, blood and liver cells.Although the liver can regenerate in the body, end-stage liver failure caused by diseases like cirrhosis and cancers eventually destroy the liver's regenerative ability, Jang says. Currently, the only option for those patients is to receive a liver organ or liver cell transplant, a supply problem given the severe shortage of donor liver tissue for transplantation. In addition, mature liver cells and adult liver stem cells are difficult to isolate or grow in the laboratory, she says. By contrast, iPSCs can be made from a tiny amount of many kinds of tissue; and the embryonic stem- like iPSCs can grow in laboratory cultures indefinitely.For the study, Jang and colleagues generated human iPSCs from a variety of adult human cells, including liver cells, fibroblasts ( connective tissue cells), bone marrow stem cells and skin cells. They found that though the iPSCs overall were molecularly similar to each other and to embryonic stem cells, they retained a distinct molecular "signature" inherited from the cell of origin.

HARBIN, March 2 (Xinhua) -- A therapeutic apparatus to treat Parkinson's disease has been developed in northeast China's Heilongjiang Province, according to the provincial science and technology department. It is a worldwide breakthrough in treating the disease with transcranial magnetic stimulation, concluded an expert panel with the Heilongjiang Provincial Department of Science and Technology.The team said it came to the conclusion after evaluating technical documents and clinical test results Monday.This is the first time that transcranial magnetic stimulation has been adopted to treat Parkinson's disease, said Sun Zuodong, chairman of Aobo Medicine Apparatus Co., Ltd. (AMA), the developer based in the provincial capital Harbin.Transcranial magnetic stimulation is a noninvasive method which causes depolarization in the brains' neurons so as to restore the functions of brain nerves.The apparatus consists of three parts, namely brain wave stimulator, field effect cap and multiplier, said Sun.Clinical tests over more than 100 patients showed that the apparatus had a 70 percent success rate in reducing the disease's symptoms, according to Wang Aili, planning manager of AMA.The new equipment will help generation of dopamine, the reduction of which within the brain caused the disease, said Wang Weixiang, a consulting doctor with the Heilongjiang Provincial Rehabilitation Hospital.Parkinson's disease is a disorder of the neural system, which leads to limb tremors and difficulty in walking and other movements.China has 2 million patients suffering from Parkinson's disease, mostly people over the age of 50, and the number is increasing by 100,000 annually, said Dr. Wang.

WASHINGTON, April 25 (Xinhua) -- The U.S. National Aeronautics and Space Administration (NASA) and the U.S. Agency for International Development (USAID) have agreed to expand their joint efforts to overcome international development challenges such as food security, climate change, and energy and environmental management.NASA Administrator Charles Bolden and USAID Administrator Rajiv Shah signed a five-year memorandum of understanding on Monday, at NASA Headquarters. The agreement formalizes ongoing agency collaborations that use Earth science data to address developmental challenges, and to assist in disaster mitigation and humanitarian responses. The agreement also encourages NASA and USAID to apply geospatial technologies to solve development challenges affecting the United States and developing countries."Technologies for NASA missions have long improved life here on Earth. Together with USAID, we'll meet even more sustainable development challenges here on the ground, solving problems for the world community," Bolden said in a statement. "As we explore space, we'll also be exploring solutions to important health, nutritional and safety challenges in developing countries."The agencies will continue collaborations to stimulate innovative science and technology solutions to international development challenges by using Earth science data, research results, computer models, visualization applications and remote- sensing techniques.USAID is the lead federal development agency implementing U.S. development efforts through field-based programs and projects around the world. NASA has broad experience with Earth science research, development of Earth science information products, and technology applications."Through our partnership with NASA, we can apply the latest, cutting-edge technology to deliver meaningful results for people in developing countries in areas like health, food security and water," Shah said. "It's a prime example of our efforts to use the power of science and technology to tackle today's pressing development challenges."Since 2003, NASA and USAID have worked together building and expanding the SERVIR program, which allows people in developing regions to use Earth observations for addressing challenges in agriculture, biodiversity conservation, climate change, disaster response, weather forecasting, and energy and health issues.The agencies also collaborate on the LAUNCH program, which supports science and technology innovators in the nonprofit and private sectors. The program's goal is improving innovations to achieve greater impact on sustainability issues.

BEIJING, Feb. 23 (Xinhua) -- The Chinese People's Political Consultative Conference (CPPCC), China's top political advisory body, opened its door to 43 correspondents from 33 overseas media outlets on Wednesday, 10 days ahead of its upcoming annual session.It was the first time that the top political advisory body invited a group of overseas journalists, including those from Hong Kong, Macao and Taiwan, to tour its work place, which used to be the site of an imperial compound 100 years ago.The media tour was hailed by Zhao Qizheng, head of the CPPCC's Committee of Foreign Affairs, as a move that reflects the "enhanced openness" of the CPPCC.During the tour, resident reporters from countries and regions such as the United States, Russia, Germany and Japan visited the CPPCC auditorium and a gallery that exhibits the agency's history and its role in Chinese political life through numerous pictures and relics.Located in downtown Beijing, the CPPCC was established on September 21, 1949. It is a patriotic united front organization for Chinese people and serves as a key mechanism for multi-party cooperation and political consultation under the leadership of the Communist Party of China (CPC).The main functions of the CPPCC are to conduct political consultations, exercise democratic supervision and participate in the discussion and the handling of state affairs. Reporters raised many questions during the visit.Watanabe Yasuhito, a staff correspondent for the Kyodo News China General Bureau, has been working in China for four years. "As Japan doesn't have similar institutions like the CPPCC, the Japanese generally have little idea of it," he said. "I now have a more direct idea of the system by actually walking into the CPPCC."He told Xinhua that Kyodo News would send eight reporters to the upcoming two annual sessions of China's National People's Congress (NPC), its national legislature and the CPPCC, as many Japanese pay close attention to the major political events in China.He said the 12th Five-Year Program and hot economic issues are among their key concerns. At a one-hour seminar held during the tour, five reporters put forward nearly 10 questions to Zhao Qizheng.Ananth Krishnan, the China correspondent of the Hindu, India's national newspaper, has covered the "two sessions" several times. "I think the next five year plan will be one of the most important issues," he said."We will be interested to see whether there are any new policies in terms of China addressing environmental challenges," he said.He added that he focused on China's reform for the household registration system at the sessions last year so that he could see how China addressed the gap between urban and rural areas."There are similar developmental challenges between India and China since we are both large developing countries with more poverty in rural populations. So we are interested to see how China is addressing the challenges," he said.With the application still going on, overseas reporters who are to cover this year's annual CPPCC session are expected to exceed 1,100, similar to the figure last year, said Zhang Jing'an, head of the Bureau of News Service of the CPPCC's National Committee.Zhang said that besides the three news conferences in the Great Hall of People, five press conferences are devoted to issues such as China's urbanization, scientific innovation, culture and education. Conferences will also be arranged in the news center following annual sessions.Also, the number of panel discussions that were open to the media increased from more than 30 in 2007 to 122 in 2010, Zhang said.Zhao Qizheng told overseas reporters that "the CPPCC will continue to enhance openness during the upcoming session and welcome reporters from both here and abroad to cover the session."China's two annual sessions, the fourth session of the National Committee of the 11th CPPCC and the fourth session of the 11th NPC, will open on March 3 and March 5, respectively.
