The world is immeasurably better because of Steve."According to a memo sent by CEO Tim Cook, Apple is planning a celebration of Jobs' life for employees that will take place soon.Jobs took a medical leave of absence earlier this year, the third in his battle with pancreatic cancer that began in 2004. On Aug. 24, he stepped down as Apple CEO, saying "I have always said if there ever came a day when I could no longer meet my duties and expectations as Apple's CEO, I would be the first to let you know. Unfortunately, that day has come."Jobs recommended former CEO Tim Cook take his place as CEO. On Tuesday, Cook gave his first product announcement as CEO unveiling the new iPhone 4S.

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, Oct. 13 (Xinhua) -- U.S. researchers have corrected sickle cell disease in adult laboratory mice that had been bred to have the inherited blood disorder by activating production of a special blood component, according to a study published online Thursday in the journal Science.Sickle cell disease results from an abnormality in hemoglobin, the protein found in red blood cells that is responsible for transporting oxygen throughout the body. People living with sickle cell disease have two copies of an altered gene that produces sickle hemoglobin instead of normal adult hemoglobin. Sickle hemoglobin changes shape after releasing its oxygen, causing the red blood cell to become stiff, misshapen and sticky, and slowing blood flow to tissues. This process damages organs and causes pain.The study tested a new approach to increasing the production of a third form of hemoglobin -- fetal hemoglobin. Production of fetal hemoglobin predominates before birth, but turns off thereafter as adult hemoglobin production takes over. People with sickle cell disease are unable to make normal adult hemoglobin, and instead make sickle hemoglobin starting in infancy.An elevated level of fetal hemoglobin within the red blood cell reduces the tendency of sickle hemoglobin to change the shape of red blood cells. Considerable research has shown that the drug hydroxyurea increases production of fetal hemoglobin and reduces the number of pain crises and other complications of sickle cell disease in adults and children. However, not all patients respond well to hydroxyurea, and adverse side effects are a concern.The current study explores a more targeted approach to increasing fetal hemoglobin production. It builds upon earlier studies that discovered a protein called BCL11A normally suppresses the production of fetal hemoglobin soon after birth. The researchers viewed the BCL11A protein as a target for therapy and decided to see what would happen if they blocked production of the protein.The paper details how the research team silenced the mouse gene that produces the BCL11A protein in mice with sickle cell disease. Silencing the gene turned off production of the BCL11A protein and allowed the adult mice to continue to produce fetal hemoglobin. It appears to have eliminated disease symptoms without affecting other aspects of blood production."This discovery provides an important new target for future therapies in people with sickle cell disease," said Susan Shurin, acting director of the U.S. National Heart, Lung, and Blood Institute, which co-funded the study. "More work is needed before it will be possible to test such therapies in people, but this study demonstrates that the approach works in principle."Approximately 100,000 Americans live with sickle cell disease. It is most prevalent in people of African, Hispanic, Mediterranean, and Middle Eastern descent. There is no widely available cure for sickle cell disease. Bone marrow transplants have cured some patients, but the treatment is not without risk and most patients do not have relatives who can donate compatible and healthy bone marrow to them.

XI'AN, Nov. 20 (Xinhua) -- Fish in Hongjiannao Lake, China's largest desert freshwater lake, are teetering on the verge of extinction, according to local fishery authorities."The fish in Hongjiannao have nearly vanished," said Li Weiping, the head of a fish monitoring station in northwest China's Shaanxi province.As the lake continues to shrink, its water has become more salty and its pH reading has reached 9.6, while the maximum reading suitable for fish is 8.5, according to Li.The lake has gradually lost the water that it used to get from underground streams and rivers, Li said, adding that excessive coal mining around the lake has changed the way water flows underground. Two reservoirs have been built on two rivers near the upper reaches of the lake, preventing river water from flowing into the lake.The lake's water level has plunged by 20 to 30 centimeters every year. Its total surface area has been reduced to 41.8 square km, down from 67 km in 1996.

BEIJING, Jan. 1 (Xinhua) -- The public on Sunday strongly echoed Chinese President Hu Jintao's New Year address broadcast on Saturday, vowing to make great efforts for rejuvenation of the nation, a better future.In his speech titled "Jointly Improve World Peace and Development," Hu said that China will continue to develop friendly exchanges with other countries and positively participate in international cooperation on global issues.The country will continue to balance maintaining steady and relatively fast economic growth with adjusting its economic structures and managing inflation expectations, Hu said in the speech.PROUD Of COUNTRY'S ACHIEVEMENTS"We have been encouraged by President Hu's address, said Wang Laihua, head of the public opinions research institute of Tianjin Social Sciences Academy."His address summarized the achievements that we have made in the first year of the 12th Five-Year Plan, which raised people's expectation for prosperity, happiness," said Wang.Hu said in the address that in the face of complicated international situations and arduous tasks in maintaining domestic reform, development and stability in 2011, Chinese people united and continued to push forward the opening up and reform drive and the socialist modernization construction, while maintaining steady and relatively fast economic growth and making progress in building a well-off society in an all-around way.Zhu Jianfang, chief economist of CITIC Securities, said that the country's macroeconomic control has made positive achievements in the last year, as the prices of properties and commodity have been effectively controlled."We feel reassured after hearing Hu's speech," said Wen Jun, who has come to south China's Guangzhou for business from Hong Kong for 16 years, referring to Hu's speech saying that China will stick to the guidelines of "one country, two systems," "Hong Kong people governing Hong Kong," "Macao people governing Macao," and a high degree of autonomy in maintaining the long-term prosperity and stability of Hong Kong and Macao.
