WASHINGTON, April 4 (Xinhua) -- The U.S. National Aeronautics and Space Administration (NASA) announced on Monday that following discussions among the International Space Station partners on Sunday, it is delaying the launch of space shuttle Endeavour's STS- 134 mission to April 29 from April 19.The new launch time is set for 3:47 p.m. EDT (1947 GMT) on Friday, April 29."The delay removes a scheduling conflict with a Russian Progress supply vehicle scheduled to launch April 27 and arrive at the station April 29," NASA said in a statement.NASA managers will hold a Flight Readiness Review on Tuesday, April 19, to assess the team's readiness to support launch. An official launch date will be selected at the conclusion of the meeting.Endeavour will deliver to the space station a 2-billion-dollar, multinational particle detector known as the Alpha Magnetic Spectrometer.

BEIJING, March 11 (Xinhuanet) --Women who have a cup or more of coffee everyday may reduce their risk of stroke by as much as 25 percent, according to a new study in the Journal Stroke Thursday. This study, led by Swedish researcher Susanna Larsson of the Karolinska Institute in Stockholm, followed more than 34,000 Swedish women aged 49 to 83 who were free of heart disease. After 10-year of follow-up, there were 1,680 strokes, and the study found that those who drank at least one cup of coffee each day had a 22 to 25 percent lowered risk of stroke, compared with women who drank less.The study further suggested coffee can help prevent cognitive decline and can boost vision and heart health. It is also related to a reduced risk of liver cancer."We used to worry that (coffee) raises blood pressure and causes increased heart rate, but it appears to be less risky than we thought," said physician Claudette Brooks, spokesperson for the American Stroke Association. Now, exactly what it is about coffee that may lower stroke risk is unknown. But the researchers speculated that coffee might reduce inflammation, lower oxidative stress and help make the body more responsive to insulin.However, some experts kept skeptical about the real impact coffee would have on reducing the incidence of stroke."The problem with this type of study is that there are too many factors unaccounted for and association does not prove causality," Dr Larry B. Goldstein, director of the Duke Stroke Center at Duke University Medical Center said."Subjects were asked about their past coffee consumption in a questionnaire and then followed over time. There is no way to know if they changed their behavior," Goldstein added.In any case, the good news for coffee junkies is that at least drinking coffee don't increase women's risk of stroke.

SAN FRANCISCO, April 20 (Xinhua) -- Apple Inc. on Wednesday reported record second fiscal quarter results that blow out analysts'expectations, citing strong demands for its products.For its fiscal 2011 second quarter ended on March 26, Apple posted net income of 5.99 billion U.S dollars or 6.4 dollars per share, compared with 3.07 billion, or 3.33 dollars per share a year ago. Its revenue reached 24.67 billion dollars, compare with 13.5 billion in the same period a year earlier.Analysts polled by Thomson Reuters gave an average estimate of 5.35 dollars earning per share on revenue of 23.3 billion."With quarterly revenue growth of 83 percent and profit growth of 95 percent, we're firing on all cylinders," said Steve Jobs, Apple's CEO. "We will continue to innovate on all fronts throughout the remainder of the year."As the most valuable business for the company, Apple sold 18.65 million iPhones in the second quarter, representing 113 percent unit growth over the year-ago quarter. In February, Apple announced that iPhone4 would come on Verizon network, enabling it to attract some 90 million Verizon subscribers to adopt the popular smartphone.The company sold 3.76 million Macs during the quarter, a 28 percent increase over the year-ago quarter, and 9.02 million iPods during the quarter, representing a 17 percent unit decline from the year-ago quarter.The company also sold 4.69 million iPads during the quarter, which is below analysts' projection. Analysts said Apple could have sold more tablets without supply constraints.Wall Street analysts estimated sales of iPad to reach about 6 million in the fiscal second quarter, alongside about 16 million iPhones and 3-4 million Macs.Apple also reported a gross margin of 41.4 percent compared to 41.7 percent in the year-ago quarter. Analyst said the decline of Apple's gross margins can be attributed to two reasons. One reason is the introduction of iPad in 2010 as it is a lower gross margin product than the iPhone. The other is the decline of iPhone margins over years.Supply chain related issues have been analysts' concern in the past quarter as Apple indicated in the Q1 earnings conference call that it could have sold more iPhones and faced some supply related issues. Meanwhile, the Japanese earthquake created more supply related issues for the company as its Japanese suppliers Mitsubishi Gas Chemical and Toshiba are both temporarily shut down to assess damage from the natural disaster.For the third fiscal quarter, Apple CFO Peter Oppenheimer gave an estimated revenue of about 23 billion and profit of 5.03 dollars per share.

HONG KONG, March 18 (Xinhua) -- After over a year's efforts, scientists from Shanghai and Hong Kong announced on Friday that they have completed the whole genomic sequencing work of Isaria cicada, a rare herb highly valued in traditional Chinese medicine, which will help facilitate its further development in medical and nutrition fields.It is the first time that the whole genomic sequence of Isaria cicada has been released, said the scientists from Shanghai Institute of Bio-Asia Life Science and the Hong Kong University of Science and Technology (HKUST), who participated in the research.The result was announced at the International Biomedical Scientists and Biotechnology Forum 2011 held in the day at the Hong Kong Science Park.According to the result, the genomic size of Isaria cicada, a medicine traditionally used to treat children's diseases, is about one eightieth of human genome, containing about 16,000 genes.The tests that had been done proved that Isaria cicada, with many high-quality genes not recognized or used by human beings yet, has been deeply involved in important life processes like metabolism, providing new ways for further development of Isaria cicad in bio-medical area, said a scientist from HKUST.The genome map will also help accelerate the artificial cultivation of Isaria cicada, enhancing its medicine and nutrition value and making it available in a larger market, according to the scientist.

JOHANNESBURG, March 8 (Xinhua) -- In order to combat piracy and to improve maritime safety, South African authorities have begun using a sophisticated navigation satellite system, it was announced on Tuesday.Piracy, especially by Somalis, has been increasing along Africa east coast in recent years. The South African Press Association (SAPA) reported on Tuesday that Karl Otto, head of the South African Maritime Safety Authority (SAMSA) announced the surveillance tool at a conference in Durban.Called Long Range Identification and Tracking (LRIT), the system monitors and tracks vessels in waters south of the equator.Otto said the introduction of the LRIT followed concerns over the safety of seafarers, the safety standards of ships within South African waters.Otto said there were high levels of cargo at risk, such as fuels and oils.He said reasons for installing the system included the number of shipwrecks along the South African coast, and the threat of pollution of the marine environment by ships."It also serves as a mechanism to prevent piracy."Otto said the satellite system has the capacity to identify and track vessels up to 1,000 nautical miles (1,850 km) from the South African coastline as well as South African-flagged vessels anywhere in the world."This is a revolutionary development in the security of our seas," he said.SAMSA was determined to protect South Africa's seafarers, its coastline and the marine environment, Otto said.
