GENEVA, Aug. 10 (Xinhua) -- In a bid to prevent millions of deaths and suffering every year from malnutrition, the Geneva-based World Health Organization (WHO) launched an online initiative on Wednesday.The e-Library of Evidence for Nutrition Actions (eLENA), according to WHO, offers the latest advice on tackling the three main forms of malnutrition, including undernutrition, vitamin and mineral deficiencies, as well as overweight and obesity.The recommendations by eLENA to tackle malnutrition include promoting breastfeeding and fortifying staple foods with vitamins and minerals such as iron and folic acid for wheat and maize flours.It also recommends using multiple micronutrient powders to fortify foods for children aged between six and 23 months.To prevent anaemia, daily iron and folic supplements are advised for pregnant women, and intermittent iron and folic acid supplementation is recommended for menstruating women and preschool and school-age.While overweight and obesity affect around 1.5 billion adults over age 20, and more than 40 million children aged under five across the world, underweight is the leading risk factor for many diseases in low-income countries and represents about six percent of the world medical burden, WHO statistics showed.

WASHINGTON, Sept. 15 (Xinhua) -- A team of researchers has discovered a planet that orbits around a pair of stars, the U.S. space agency NASA announced Thursday.This is the first instance of astronomers finding direct evidence of a so-called circumbinary planet. A few other planets have been suspected of orbiting around both members of a dual-star system, but the transits of the circumbinary planet have never been detected previously.The team, led by Laurance Doyle of the SETI Institute in California, used photometric data from the NASA Kepler space telescope, which monitors the brightness of 155,000 stars.NASA's Kepler mission has discovered a world where two suns set over the horizon instead of just one. The planet, called Kepler-16b, is the most "Tatooine-like" planet yet found in our galaxy. Tatooine is the name of Luke Skywalker's home world in the science fiction movie Star Wars. In this case, the planet it not thought to be habitable. It is a cold world, with a gaseous surface, but like Tatooine, it circles two stars.They found the binary star system by detecting a system where the stars eclipsed each other from the perspective of the Kepler spacecraft. These stars have two eclipses: A primary eclipse when the larger star is partially blocked by the smaller star and a secondary eclipse where the smaller star is fully blocked by the larger star.But the researchers also noticed other times when the brightness of the two stars dropped, even when they were not in an eclipse position. This pattern suggested that there was likely a third object involved. The fact that these so-called tertiary and quaternary eclipses recurred after varying intervals of time, and were of different depths, indicated that the stars were in different positions in their orbit at each instance. This result showed that the tertiary and quaternary eclipses were being caused by something circling both stars, and not an object circling one or the other star.Measurements of the variations in the timing of all four types of eclipses, resulting from the mutual gravitational interactions of the two stars and the third body, demonstrated that the third object was, indeed, a planet. Their work indicates that the planet is less massive than Jupiter, possibly comparable in mass to Saturn, and that the larger of the two binary stars is smaller than our Sun.Their findings will be published Friday in Science."This discovery confirms a new class of planetary systems that could harbor life," Kepler principal investigator William Borucki said in a statement. "Given that most stars in our galaxy are part of a binary system, this means the opportunities for life are much broader than if planets form only around single stars. This milestone discovery confirms a theory that scientists have had for decades but could not prove until now."

MOSCOW, Sept. 16 (Xinhua) -- A Russian Soyuz space capsule carrying three astronauts returned to the Earth Friday, the Mission Control Center outside Moscow confirmed.The three astronauts, two Russians and one American from the International Space Station (ISS), who were flown back by a Soyuz TMA-21 spacecraft, were in good condition, search and rescue teams on the ground in Kazakhstan said.Russian TV images showed the three ISS crew members being taken out of the space capsule and seated in armchairs with blankets to re-adapt to the Earth's gravity.According to the Cosmonaut Training Center, the astronauts underwent physical examinations immediately after the landing, which included examinations of hearts, lungs and adrenal glands.Seventeen helicopters and planes had waited for the capsule's landing.Helicopters will carry the astronauts from the landing site to the Kazakh city of Karaganda, from where the two Russian cosmonauts Alexander Samokutyayev and Andrei Borisenko will fly back to Moscow later Friday, while NASA astronaut Ronald Garan will leave directly for the United States for post-mission rehabilitation, the Itar-Tass news agency reported.The return of the three crew members was originally scheduled for Sept. 8, but was postponed by a failed launch of the Progress cargo ship on Aug. 24.The three crew members remaining on board the ISS are scheduled to return in mid-November.

BEIJING, July 6 (Xinhua) -- The Ministry of Health has issued a national standard on compound food additives to better regulate the production and use of such additives and ensure food safety.Compound food additives, which are designed to improve food quality or assist in food processing, should be used sparingly in food products, according to the standard the ministry issued Tuesday.Titled the General Rule on Compound Food Additives, the standard stipulates that each of the ingredients used for making compound food additives, which are a mix of two or more single food additives, should meet national standards concerning food safety.No chemical reaction should occur and no new compounds should be generated during the production process of compound food additives, according to the standard.Compound food additives producers should clarify limits of the amounts of harmful substances, such as lead and arsenic, in their products and take measures to control the levels of harmful substances, according to the standard, which will come into effect on Sept. 5 this year.

SAN FRANCISCO, July 19 (Xinhua) -- Apple Inc. on Tuesday reported strong third fiscal quarter results that top analysts' expectations, citing strong iPhone and iPad sales.For its fiscal 2011 third quarter ended on June 25, Apple reported net income of 7.31 billion U.S. dollars or 7.79 dollars per share, compared with 3.25 billion dollars, or 3.51 dollars per share a year ago.Its revenue reached 28.57 billion dollars, compared with 15.7 billion dollars in the same period a year earlier. International sales accounted for 62 percent of the quarter's revenue.The average estimate is a profit of 5.84 dollars a share on revenue of 24.9 billion dollars.The Cupertino, Califronia-based company sold 20.34 million iPhones in the quarter, representing 142 percent unit growth over the year-ago quarter. It sold 9.25 million iPads in the third quarter, a 183 percent unit increase on a year-over-year basis.The only drawback is the sales of iPods, which had a 20 percent unit decline to 7.54 million from the year-ago quarter."We're thrilled to deliver our best quarter ever, with revenue up 82 percent and profits up 125 percent," Steve Jobs, Apple's chief executive officer, said in a statement."Right now, we're very focused and excited about bringing iOS 5 and iCloud to our users this Fall," added Job.It is the first time since 2008 that Apple's third-quarter earnings does not include the release of a new iPhone, which, slated for launch in September, is reportedly to be thinner and lighter with a faster chip and 8-megapixel camera.Apple has enjoyed double-digit year-over-year percentage revenue growth for the past four quarters. It had previously beaten the average earning projection for at least 29 straight quarters, according to data compiled by Bloomberg.For the fourth fiscal quarter of 2011, Apple's chief financial officer Peter Oppenheimer said the company expects revenue of 25 billion dollars and earnings per share of about 5.5 dollars. Apple has been known for its conservative projections of earnings.Apple has been operating without the daily attention of Jobs since the CEO took a medical leave this January. The Wall Street Journal reported Tuesday that some members of Apple's board have discussed CEO succession with executive recruiters and at least one head of a high-profile technology company.But the people familiar with the matter told the newspaper that it was more of an informal exploration of the company's options and don't appear to have been acting on behalf of the full board.Meanwhile, Apple has recently been busy with a number of legal battles over patent rights with HTC, Eastman Kodak and Samsung.Last week, the U.S. International Trade Commission made an initial ruling that HTC infringed two of Apple's phone patents in its smartphones powered by Google's Android operating system.If upheld, the ruling could let Apple force other Android phone makers to pay significant patent fees.On Tuesday, Google's executive chairman Eric Schmidt said at a conference in Tokyo that Apple's smartphone lawsuits are inspired by jealousy and a lack of innovation in iPhone, noting Google would support HTC's fight against Apple and was confident of a win.
