HAIFA, Israel, Oct. 5 (Xinhua) -- "It's a big day, a celebration shared by Israel, science and the entire world," Israeli researcher Daniel Shechtman, who won the 2011 Nobel Prize in chemistry, said here at a press conference at the Technion- Israel Institute of Technology.Shechtman, 70, has spent the past five decades at Technion. He is also an associate at the Ames Laboratory of the U.S. Department of Energy and has lectured at universities abroad."Thousands of scientists are currently researching the subject I developed and I'm sure that all of them view the prize as their accomplishment too," he told Xinhua, adding that, "Science (in general) wouldn't be here and be as prosperous and intricate as it is if not for the work of thousands of others around the world."The Swedish Royal Academy of Sciences on Wednesday announced Shechtman as the winner of this year's Nobel chemistry prize for his cutting-edge research on quasicrystals, a type of atom form that for decades was considered impossible by the global scientific community.The award panel explained that Shechtman's work, launched in early 1980s, has revolutionized the perception of solid matter.His work forced crstyallographers to revamp their basic conception that atoms inside crystals only have repeating and symmetrical patterns.Shechtman is the 10th Israeli scientist to win the Nobel Prize and the fourth to win the prize in chemistry.Ada Yonat, a researcher at the Weizmann Institute near Tel Aviv, received the chemistry prize in 2009.The announcement from Stockholm captured headlines in Israel, drawing praise from the country's leadership, who said Shechtman's achievement is a testament to the Jewish state's stature as a technological powerhouse.Israeli Prime Minister Benjamin Netanyahu said the winning of the Nobel Prize "expresses our people's intellect.""Every Israeli citizen is happy today and every Jew in the world is proud," a statement issued by Netanyahu's office quoted him as telling the scientist in a telephone call.Israeli President Shimon Peres, who is also a Nobel laureate, later called to congratulate Shechtman."You demonstrate that a thinking person who is hardworking and brave can make groundbreaking scientific discoveries," he said.

WASHINGTON, Jan. 2 (Xinhua) -- A systematic review of previous studies suggests that there may be a positive connection between physical activity and children's academic performance, according to a report published Monday in the Archives of Pediatrics & Adolescent Medicine.A group of scientists at the Vrije Universiteit (Free University) Medical Center in the Netherlands reviewed evidence on the relationship between physical activity and academic performance because of concerns that pressure to improve test scores may often mean more instructional time for classroom subjects with less time for physical activity.The authors identified 10 observational and four interventional studies for review, 12 of which were done in the United States, one in Canada and one in South Africa. Sample sizes ranged from 53 to about 12,000 participants between the ages of eight years and 18 years old. Follow-up varied from eight weeks to more than five years."According to the best-evidence synthesis, we found strong evidence of a significant positive relationship between physical activity and academic performance. The findings of one high-quality intervention study and one high-quality observational study suggest that being more physically active is positively related to improved academic performance in children," the report said.Background information in the article suggests that exercise may help cognition by increasing blood and oxygen flow to the brain, increasing levels of norepinephrine and endorphin to decrease stress and improve mood, and increasing growth factors that help create new nerve cells and support synaptic plasticity."More high-quality studies are needed on the dose-response relationship between physical activity and academic performance and on the explanatory mechanisms, using reliable and valid measurement instruments to assess this relationship accurately," the report concluded.

BAIKONUR, Kazakhstan, Nov. 9 (Xinhua) -- Russia's Phobos-Grunt probe and China's Yinghuo-1 satellite were launched from the Baikonur cosmodrome in Kazakhstan on a Zenit-2SB rocket at 00:16 am Moscow time Wednesday (2016 GMT Tuesday).The main aim of the Phobos-Grunt unmanned mission is to bring back the first ever soil sample from Phobos, the larger of Mars' two moons.Russia had spent about 5 billion rubles (about 161 million U.S. dollars) preparing for the three-year mission, which would include drilling Phobos' surface and returning 200 grams of soil back to Earth, according to Russian state space agency Roscosmos.The mission would also collect bacteria samples for two Russian and one U.S. biological experiments.In the meantime, China's first Mars probe Yinghuo will go into orbit around Mars and observe the planet itself.Phobos-Grunt is planned to reach Mars in 2012, then deploy its lander for Phobos in 2013 and return the soil sample back to Earth in August 2014.The Chinese probe, which would not land on Mars nor return to the Earth, is expected stay permanently in the space and communicate with the ground control directly via satellites.The Chinese probe is 75 cm long, 75 cm wide and 60 cm high. It weighs 115 kilograms and was designed for a two-year life to discover why water disappeared from Mars and shed light on other environmental changes on the planet.Victor Khartov, chief designer and director general of Lavochkin Research & Production Association, told Xinhua that the three-year mission is highly complicated."It consists of eight sub-missions: launch, travel to Mars vicinities, separation with the Chinese probe YH-1, landing on Phobos, soil collection, launch from Phobos, way back to the Earth, and final landing. Failure of any one of them could doom the entire project," he said.The launch of Phobos-Grunt and Yinghuo-1, originally scheduled for October 2009 on a Russian carrier rocket, has been postponed until 2011 due to "technical reasons" on the Russian side.

SAN FRANCISCO, Dec. 13 (Xinhua) -- Apple is in talks to acquire Israeli fabless semiconductor maker Anobit for 400 million to 500 million U.S. dollars, U.S. media reported on Tuesday.Apple is likely interested in Herzliya Pituach, Israel-based Anobit for an exclusive access to its embedded flash controllers which can significantly boost memory performance of smartphones and tablet computers, said technology news site TechCrunch, citing Calcalist, an Israeli newspaper in Hebrew which first reported the possible acquisition.Apple already uses Anobit's technology in iPhone, iPad and the MacBook Air.If the deal works out, it could be Apple's largest acquisition ever, surpassing its 404 million-dollar purchase of NeXT in 1997.It could also become Apple's first acquisition in Israel and the first with Tim Cook as the chief executive officer of the company since its iconic leader Steve Jobs passed away in early October.

NANJING, Dec. 20 (Xinhua) -- Chinese Premier Wen Jiabao has called for the country to maintain confidence that it can weather challenges amid a "complicated and tough" outlook of economic development."As in 2008, we are now encountering difficulties which can be overcome through hard work," Wen said during his tour to eastern Jiangsu province on Sunday and Monday.Elaborating on the grim situation, Wen said the growth of China's exports has been slowing and the pace of the slowdown has accelerated, especially in the past three months. Meanwhile, the profit margin of the country's manufacturing industry has been squeezed and some enterprises have even fallen into the red.Chinese Premier Wen Jiabao (C) talks to staff members in a small loan company for rural areas in Suzhou National New & Hi-Tech Industrial Development Zone in Suzhou City, east China's Jiangsu Province, Dec. 19, 2011. Wen Jiabao made an inspection tour in Jiangsu on Dec. 18 and 19. He noted that the country is also facing shrinking external demand, rising costs and pressure from both slowing economic growth and high inflation, which makes macro-economic regulation more difficult.Despite emerging challenges, however, the current momentum of China's economic development is "generally good," Wen said.China's economic growth has been slowing all year but remains above the global average. Its GDP growth slowed to 9.1 percent in the third quarter from 9.5 percent in the second quarter and 9.7 percent in the first quarter.To tackle the challenges, Wen said the country will boost domestic demand while stabilizing external demand and keep its export policies such as export tax rebates "basically stable" in the coming year.Efforts should also be made to enhance domestic enterprises' competitiveness, promote the transfer of industry to the country's western regions, and develop the international market, especially in emerging economies, he said.He said China will stick to, and further improve upon, the opening-up policy and welcome foreign enterprises to invest in the country, adding that the country will protect intellectual property rights and implement a fair and open bidding approach in terms of government procurement.Wen also demanded efforts be made to encourage private investment in sectors such as railways, public facilities, finance, energy, education and health-care.Furthermore, he urged banks to take concrete action in better serving the real economy and asked financial institutions to enhance support for enterprises while improving management in order to control the capital bubble and prevent risks.Wen said the southern parts of Jiangsu should engage in a comprehensive development strategy to build the province into a forefront of the country's opening-up drive.
