TEHRAN, Oct. 9 (Xinhua) -- Iran is going to launch domestically- built Navid satellite by Safir satellite launcher by the end of March 2012, the semi-official Mehr news agency reported on Sunday.Navid (promise) is a research satellite and is currently undergoing pre-launch tests, said the report without further details.In June, Iran put the Rasad (surveillance) satellite in the orbit to render images to the country.Iran put a satellite into orbit in 2009 and sent some small animals into space in 2010. It plans to send man into space by 2020.

CAPE TOWN, Dec. 15 (Xinhua) -- More people voluntarily get HIV tests in the Western Cape province, an indication of people's rising awareness of the epidemic, authorities said on Thursday.Nearly 11,000 people in the province have been tested over the past 10 days as authorities stepped efforts to halve the number of HIV transmissions over the next few years, according to official figures.Authorities expect more people to be tested when the monthly campaign ends by the end of December.In December last year, 67,111 people were tested.This year's figure is expected to be higher than that of last year, said Western Cape Premier Helen Zille.The campaign, known as Know Your Status and Win, may become a regular feature in the province, said Zille.To encourage more people to take part in the campaign, the province offers awards to several winners by drawing, ranging from 10,000 rand (about 1,250 U. S. dollars) to 50,000 rand (about 6, 250 dollars)."The bottom line is that people respond to incentives," said Zille, who hailed the campaign a success.She said the reality was that those who stubbornly did not want to get tested, were those crucially in need of doing so.While the data still had to be audited, preliminary results indicated a spike in the number of people who were tested.There was also a significant increase at routine testing center that were not part of the campaign, said Zille. Of 22.9 million HIV positive people in sub-Saharan Africa, 5.6 million in South Africa, according to an annual report by UNAIDS.

WASHINGTON, Nov. 10 (Xinhua) -- NASA's car-sized Mars rover Curiosity, which will examine one of the most intriguing areas on the Red Planet, is in final preparations for a launch from Florida 's Space Coast at 10:25 a.m. EST (15:25 GMT) on Nov. 25, the U.S. space agency announced on Thursday.Curiosity is about twice as long and more than five times as heavy as any previous Mars rover. Its 10 science instruments include two for ingesting and analyzing samples of powdered rock delivered by the rover's robotic arm. It is now sitting atop an Atlas V rocket awaiting liftoff from Cape Canaveral Air Force Station."Preparations are on track for launching at our first opportunity," said Pete Theisinger, Mars Science Laboratory project manager at NASA's Jet Propulsion Laboratory. "If weather or other factors prevent launching then, we have more opportunities through Dec. 18."Scheduled to land on the Mars in Aug. 2012, the one-ton rover will examine Gale Crater during a nearly two-year prime mission. Curiosity will land near the base of a layered mountain three miles (five kilometers) high inside the crater. The rover will investigate whether environmental conditions ever have been favorable for development of microbial life and preserved evidence of those conditions.

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.

BEIJING, Nov. 22 (Xinhuanet) -- Women aged 40 to 49 are not recommended for routine mammography screening for breast cancer, said the new guidelines issued by the Canadian Task Force on Preventive Health Care in media reports Tuesday.The new guidelines are purposed to direct doctors on using mammography, MRI scans, clinical breast exams and breast self-exams. In principle, they pointed out, there is no need for women to take clinical breast exams and breast self examination if there are no signals for breast cancer.Below are the main points from the guidelines which need special attention from women with reasonable doubt on the matter:Women aged 40-49 who have lower risk for cancer should not take routine mammography because of the higher risk for overdiagnosis, overtreatment and false-positives;Women aged 50 to 69 years and aged 70 to 74 years should go for routine screening every two to three years;And there should be no routine clinical breast exams by doctors and no breast self-exams to screen for breast cancer.Dr. Marcello Tonelli, Chair of the Task Force and Associate Professor at the University of Alberta, remarked: "The main effect of screening is to produce patients with breast cancer from among healthy women who would have remained free of breast disease for the rest of their lives had they not undergone screening.""The best method we have to reduce the risk of breast cancer is to stop the screening program," he added, "This could reduce the risk by one-third in the screened age group, as the level of overdiagnosis in countries with organized screening programs is about 50 percent."
