WASHINGTON, Oct. 3 (Xinhua) -- Researchers at St. Michael's Hospital in Canada have discovered a new function for an enzyme that may protect against organ injury and death from anemia, according to a study appearing Monday in the U.S. journal of the Proceeding of the National Academy of Sciences.Researchers found that when people have anemia, neuronal nitric oxide synthase (nNOS) -- an enzyme in nerve cells that produces nitric oxide, an important signaling molecule in the body -- increases the body's ability to respond, adapt to low oxygen levels and makes the body more efficient in delivering oxygen to tissues. They also found that levels of nNOS in the brain increased in anemic mice, and that the mice without this enzyme die earlier, and with higher hemoglobin levels."Identifying this mechanism may lead to new therapies and approaches to improving outcomes for anemic patients," said Dr. Greg Hare, a researcher at the Li Ka Shing Knowledge Institute of the hospital and one of the lead investigators of the study.Anemia occurs when blood has a lower than normal number of red blood cells or hemoglobin -- an iron-rich protein that carries oxygen from the lungs and heart to the rest of the body. Cells need oxygen to survive and to produce energy for all bodily functions. The condition has many different causes including infection (malaria, HIV, parasites), nutritional deficiencies (iron, folate, B12), genetic mutations, pregnancy, trauma and surgical blood loss."This research will help us identify when an anemic patient is at greatest risk for injury and death when undergoing surgery," said Hare. "Research is underway to test these findings in humans."

NEW YORK, Oct. 14 (Xinhua) -- The iPhone 4S went on sale at Apple store on the Fifth Avenue of Manhattan in New York early Friday.An Apple store worker said people were waiting outside the store around 3 p.m. Thursday and underwent an overnight rain for an early purchase of the smart phone which started sale at 8 a.m. Friday.About 200 people were seen lining up outside the store and some of them said they would like to pay tribute to Steve Jobs, Apple's longtime CEO who died of pancreatic cancer at the age of 56 on Oct. 5."I'm a Steve's fan, iPhone 4S is the best of Steve's work. I am not going to buy iPhone 5,"Jim Bedford, who is in his 30s, said. "Maybe this is my last iPhone," he added.People left a Steve's picture, flowers and apples on the sidewalk to pay respect to Apple's co-founder. Some apples were seen inscribed such words as "Nice job" and "We will always remember you."Tom White, 50, said he had iPhone 1 and 3 and "now is the time to change a new one."The iPhone 4S is operated seven times faster than their predecessor and features an upgraded camera. Apple reported more than 1 million pre-orders for the iPhone 4S, breaking a mark set by last year's model. The phone also went on sale Friday in six other countries -- Britain,Germany,France,Australia, Canada and Japan.

BEIJING, Dec. 29 (Xinhua) -- China on Thursday issued a white paper on the development of space industry since 2006 and the major tasks for the next five years.The white paper titled "China's Space Activities in 2011" was the third white paper on the country's space activities issued by the State Council Information Office, following the one in 2000 and another in 2006.The Chinese government has made the space industry an important part of the nation's overall development strategy and adhered to exploration and utilization of outer space for peaceful purposes, the white paper said.Over the past few years, China has ranked among the world's leading countries in certain major areas of space technology, it said, adding that in the next five years, there will be new opportunities to the country's space industry.At the same time, China will work together with the international community to maintain a peaceful and clean outer space and endeavor to promote world peace and development, the document said.FUTURE MISSIONSMajor tasks listed in the white paper for the next five years include space transportation system, Earth satellites, human spaceflights and deep-space exploration.The country will launch the Shenzhou-9 and Shenzhou-10 spaceships and achieve unmanned or manned rendezvous and docking with the in-orbit Tiangong-1 vehicle, the paper said.China also plans to launch space laboratories, manned spaceship and space freighters, and will start a research on the preliminary plan for a human landing on the moon, the document said.As an important part of deep-space exploration, the country's lunar probe projects follow the idea of "three steps" -- orbiting, landing and returning.In next five years, the country plans to launch orbiters for lunar soft landing, roving and surveying to implement the second stage of lunar exploration, then it will start the third-stage project of sampling the moon's surface matters and get those samples back to Earth, the white paper said.In addition, China will build a space infrastructure frame composed of Earth observation satellites, communications and broadcasting satellites, plus navigation and positioning satellites.MAJOR PROGRESSAccording to the white paper, breakthroughs have been made in major space projects, including human spaceflight and lunar exploration, since 2006.From Sept. 25 to 28, 2008, China successfully launched the Shenzhou-7 manned spaceship and became the third country in the world to master the key technology of astronaut space extravehicular activity.In November 2011, China accomplished the first unmanned space rendezvous and docking test between the Tiangong-1 space lab module and Shenzhou-8 spaceship.In addition, the country's lunar probe projects have achieved milestone breakthroughs over the past five years. China successfully launched two lunar probes, the Chang'e-1 on Oct. 24, 2007, and Chang'e-2 on Oct. 1, 2010.The first probe retrieved a great deal of scientific data and a complete map of the moon while the second created a full higher-resolution map of the moon and a high-definition image of Sinus Iridium.
