HAVANA, Aug. 15 (Xinhua) -- Cuba's Ministry of Public Health launched an intensive sanitation campaign Monday against the Aedes Aegypti mosquito, which can spread dengue fever.The operation, which is running through Sept. 15, will cover the most vulnerable cities in the country, including the capital Havana and the eastern city Guantanamo.Deputy Health Minister Luis Estruch stressed the importance of the prevention campaign and urged all families to check their houses for mosquitoes each week.Maria Guadalupe Guzman, director of the Pan-American and World Health Organization Cooperation Center for the Study of Dengue and Its Vector at the Pedro Kouri Institute of Tropical Medicine, said the epidemiological situation in the country is stable. However, she warned that an epidemic outbreak is still possible in the island state, given the high temperatures and heavy rains in the eastern areas, and drought in the west.Cuba, along with Chile and Uruguay, are the only Latin American countries where dengue is not endemic.In 1981, the country suffered its worst dengue outbreak in history, which left 158 dead.

WASHINGTON, Sept. 27 (Xinhua) -- Debris from NASA's decommissioned Upper Atmosphere Research Satellite (UARS) that crashed to Earth on Saturday fell harmlessly in a remote area of the South Pacific Ocean, NASA said on Tuesday.According to the space agency, the Joint Space Operations Center at Vandenberg Air Force Base in California has determined the satellite entered the atmosphere over the Pacific Ocean at 14.1 degrees south latitude and 170.2 west longitude at midnight EDT Saturday. The debris field is located between 300 miles and 800 miles downrange, or generally northeast of the re-entry point."This location is over a broad, remote ocean area in the Southern Hemisphere, far from any major land mass," NASA announced, adding that it is "not aware of any possible debris sightings from this geographic area."NASA scientists estimated a 1-in-3,200 chance a satellite part could hit someone on earth. Therefore, any individual's odds of being struck are about one in 21 trillion.The UARS satellite, launched in 1991 from a space shuttle, was the first multi-instrumented satellite to observe numerous chemical constituents of the atmosphere with a goal of better understanding atmospheric photochemistry and transport.

BEIJING, Aug. 3 (Xinhuanet) -- The first man in Britain who received a complete plastic heart is allowed to leave hospital and live a relatively normal life at home.Matthew Green, 40, who was dying from arrhythmogenic right ventricular cardiomyopathy, was awaiting a transplant when his condition became so bad that the doctors at Papworth Hospital, the world renowned heart center near Cambridge, decided to give him Britain’s first ever full artificial heart.During a six-hour operation on June 9, 2011, surgeons replaced Mr Green's damaged heart with the device which will serve the role of muscles and ventricles.Unlike previous artificial hearts, they have usually only replaced parts of the organ, the new one is powered by a pump which sits outside the body and can be held in a backpack or shoulder bag.All Mr Green has to do is replace the batteries in the pump every few hours and the heart should last up to three years.Transplant milestones1964 US National Institutes of Health starts artificial heart programme.1966 First transplant of partial mechanical heart, to assist pumping of ventricle.1969 Texas man receives first total artificial heart transplant. After 64 hours on the mechanical device received a donor organ, but died within two days.1982 Artificial heart designed by Utah University doctor Robert Jarvik implanted into man who survived for 112 days.2001 First surgical implant of internally powered artificial heart, which was charged via transduction through skin.

SAN FRANCISCO, Sept. 13 (Xinhua) -- Intel and Google on Tuesday announced a partnership to enable the world's largest chip maker's architecture on the search giant's products, saying that an Intel chip-based Android smartphone will hit the market in the first half of 2012.In a joint press release, the two companies said the future versions of Android mobile operating system will support Intel's low power Atom processors, in addition to other architectures.At the Intel Developer Forum in San Francisco on Tuesday, Intel Chief Executive Officer Paul Otellini said the Intel smartphone chip is code-named Medfield and based on the company's own PC- based computer architecture.Otellini said multiple vendors around the world will launch the Medfield-based Android smartphones in the first half of 2012.Andy Rubin, senior vice president of mobile at Google, came on stage at the close of Otellini's keynote to hail the joint initiatives between the two companies.Intel has been struggling to get a bite of the booming market of smartphones and tablets. Most of the current mobile devices use chips based on architecture from ARM Holdings, which are considered more power efficient than Intel's products. Nokia had planned to ship smartphones with Intel chips this year, but it shifted to ARM-based phones with Windows Phone 7 system.Otellini said Intel will eventually have an advantage in supplying smartphone chips as the business is not established in terms of the final winner and performance of the products keeps growing.
