LOS ANGELES, July 6 (Xinhua) -- NASA scientists have got the first-ever, up-close details of a Saturn storm that is eight times the surface area of Earth, the Jet Propulsion Laboratory ( JPL) announced on Wednesday.The images were captured by NASA's Cassini spacecraf, according to JPL in Pasadena, Los Angeles.On Dec. 5, 2010, Cassini first detected the storm that has been raging ever since. It appears approximately 35 degrees north latitude of Saturn.The storm is the biggest observed by spacecraft orbiting or flying by Saturn. NASA's Hubble Space Telescope captured images in 1990 of an equally large storm.Pictures from Cassini's imaging cameras show the storm wrapping around the entire planet covering approximately two billion square miles (4 billion square kilometers).The storm is about 500 times larger than the biggest storm previously seen by Cassini during several months from 2009 to 2010. At its most intense, the storm generated more than 10 lightning flashes per second.Cassini has detected 10 lightning storms on Saturn since the spacecraft entered the planet's orbit.Those storms rolled through an area in the southern hemisphere dubbed "Storm Alley." "Cassini shows us that Saturn is bipolar," said Andrew Ingersoll, a Cassini imaging team member at the California Institute of Technology in Pasadena, California. "Saturn is not like Earth and Jupiter, where storms are fairly frequent. Weather on Saturn appears to hum along placidly for years and then erupt violently. I'm excited we saw weather so spectacular on our watch."The new details about this storm complement atmospheric disturbances described recently by scientists using Cassini's composite infrared spectrometer and the European Southern Observatory's Very Large Telescope. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. NASA's JPL manages the mission for the agency's Science Mission Directorate in Washington.

TAMPA, the United States, June 18 (Xinhua) -- The HIV/AIDS patients in the U.S. state of Florida are in dispute with state authorities over a proposal to impose tighter restrictions on those who qualify for drugs provided by the state's AIDS Drug Assistance Program (ADAP).According to the proposed restrictions, individuals would have to earn less than 21,000 U.S. dollars annually to qualify for ADAP drugs. If approved by the Florida Department of Health (FDH), this would affect approximately 1,150 HIV/AIDS patients."The FDH is currently looking at the number of cost containment activities, including altering the financial eligibility for ADAP services," said FDH's press secretary Jessica Hammonds. "After soliciting public input on this matter, the department is in the final stages of evaluating the matter."The Florida ADAP program serves almost 9,500 clients, each of whom receiving 8,600 dollars in funding annually, Hammonds said. There are still another 3,482 on a waiting list.Four FDH sponsored public hearings were held in April and May on the proposal to reduce HIV/AIDS funding. Two were held in Miami, one in Tampa, and the other one was held in the state capital city of Tallahassee. Over 1,000 people attended the hearings.The issue has become so ubiquitous that it caught the attention of the Elton John AIDS Foundation (EJAF), created by the popular entertainer of the same name.

LOS ANGELES, July 18 (Xinhua) -- The spacecraft Dawn of the National Aeronautics and Space Administration (NASA) has returned the first close-up image of the giant asteroid Vesta after entering its orbit for the first time last week, the Jet Propulsion Laboratory (JPL) announced on Monday.The image taken for navigation purposes shows Vesta in greater detail than ever before, said JPL in Pasadena, California.On July 15, Dawn became the first probe to enter orbit around an object in the main asteroid belt between Mars and Jupiter.When Vesta captured Dawn into its orbit, there were approximately 9,900 miles (about 16,000 kilometers) between the spacecraft and the asteroid.Vesta is 330 miles (about 530 kilometers) in diameter and the second most massive object in the asteroid belt.NASA's Dawn spacecraft obtained this image with its framing camera on July 17, 2011. It was taken from a distance of about 9,500 miles (15,000 kilometers) away from the protoplanet Vesta. Each pixel in the image corresponds to roughly 0.88 miles (1.4 kilometers). Ground- and space-based telescopes have obtained images of Vesta for about two centuries, but they have not been able to see much detail on its surface."We are beginning the study of arguably the oldest extant primordial surface in the solar system," said Dawn principal investigator Christopher Russell from the University of California, Los Angeles, which is responsible for Dawn's mission science. " This region of space has been ignored for far too long. So far, the images received to date reveal a complex surface that seems to have preserved some of the earliest events in Vesta's history, as well as logging the onslaught that Vesta has suffered in the intervening eons."Vesta is thought to be the source of a large number of meteorites that fall to Earth. Vesta and its new NASA neighbor, Dawn, are currently approximately 117 million miles (about 188 million kilometers) away from Earth. The Dawn team will begin gathering science data in August.Observations will provide unprecedented data to help scientists understand the earliest chapter of the solar system and pave the way for future human space missions, according to JPL."Dawn slipped gently into orbit with the same grace it has displayed during its years of ion thrusting through interplanetary space," said Marc Rayman, Dawn chief engineer and mission manager at NASA's JPL. "It is fantastically exciting that we will begin providing humankind its first detailed views of one of the last unexplored worlds in the inner solar system."Although orbit capture is complete, the approach phase will continue for about three weeks. During approach, the Dawn team will continue a search for possible moons around the asteroid; obtain more images for navigation; observe Vesta's physical properties; and obtain calibration data.In addition, navigators will measure the strength of Vesta's gravitational tug on the spacecraft to compute the asteroid's mass with much greater accuracy than has been previously available, according to JPL.Dawn will spend one year orbiting Vesta, then travel to a second destination, the dwarf planet Ceres, arriving in February 2015. The mission to Vesta and Ceres is managed by JPL for the agency's Science Mission Directorate in Washington.Dawn is a project of the directorate's Discovery Program, which is managed by NASA's Marshall Space Flight Center in Huntsville, Alaska.

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.

BEIJING, Aug. 24 (Xinhuanet)-- A new study shows that a diet rich in cholesterol-friendly foods, such as soy products and tree nuts, can decrease LDL (bad) cholesterol significantly, according to media reports on Tuesday.The study, published in the Journal of the American Medical Association, found that people who ate a healthy diet filled with cholesterol-lowering foods experienced a 13 percent decrease in their LDL cholesterol levels.For patients with high levels of so-called bad cholesterol, doctors usually have two prescriptions: cholesterol-lowering statin drugs and a diet that cuts out foods high in saturated fat, such as ice cream, red meat and butter.But the new study found that when it comes to lowering artery-clogging cholesterol, what you eat may be more important than what you don't eat.David Jenkins of St. Michael's Hospital and the University created the "portfolio diet," which includes regular consumption of tree nuts and high amounts of fiber from oats, barley and vegetables. The diet, which replaces butter with plant sterol-enriched margarine and substitute soy-based products for meat, allows maximum benefit in lowering cholesterol and preventing heart disease. "The study highlighted the power of food to lower risk for cardiovascular disease: What you do eat and what you don't eat are both important," said Dr. Jane Klauer, a New York internist specializing in metabolism and nutrition.A high overall cholesterol level makes a person nearly twice as likely to suffer a heart attack or stroke as someone whose total cholesterol falls into a healthy range.
