WASHINGTON, Nov. 21 (Xinhua) -- The launch of the Mars Science Laboratory, which contains the car-sized Curiosity rover, has been delayed by a day to Nov. 26, the U.S. National Aeronautics and Space Administration (NASA) announced Monday.The delay will "allow time for the team to remove and replace a flight termination system battery," NASA said in a statement.The launch is now scheduled for 10:02 a.m. (1502 GMT) on Saturday from Cape Canaveral Air Force Station, Florida. The launch window remains open for one hour and 43 minutes.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.Scheduled to land on the Mars in August 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.

JINAN, Oct. 24 (Xinhua) -- Chinese scientists have made a breakthrough that could lead to more effective treatments for leprosy.A team from Shandong Provincial Institute of Dermatology and Venereology in east China has identified two new risk variants near IL23R and RAB 32 genes that are responsible for the disease, according to a report published online Monday in the scientific journal Nature Genetics.Knowing that the two gene variants influence susceptibility to leprosy could allow doctors to diagnose the disease in sufferers earlier in its outset, as well as to develop new treatments. A genetic database could now be built up to predict those people particularly susceptible to leprosy, said Zhang Furen, the leader of the research team.The study involved more than 10,000 samples being taken from leprosy sufferers and healthy test subjects and analysed.Leprosy is a chronic nerve-killing disease that leads to problems with patients' skin, feet, hands, legs and eyes. More than 200,000 newly-contracted leprosy cases are reported worldwide every year, and China has around one tenth of the world's sufferers. 

WASHINGTON, Jan. 16 (Xinhua) -- A new study examining weather patterns around the worldwide pandemics of influenza, which caused widespread death and illness in 1918, 1957, 1968 and 2009, finds that each of them was preceded by La Nina conditions in the equatorial Pacific. The study findings are published online Monday in the Proceedings of the National Academy of Science.The study's authors -- Jeffrey Shaman of Columbia University's Mailman School of Public Health and Marc Lipsitch of the Harvard School of Public Health -- note that the La Nina pattern is known to alter the migratory patterns of birds, which are thought to be a primary reservoir of human influenza. The scientists theorize that altered migration patterns promote the development of dangerous new strains of influenza.To examine the relationship between weather patterns and influenza pandemics, the researchers studied records of ocean temperatures in the equatorial Pacific in the fall and winter before the four most recent flu pandemics emerged. They found that all four pandemics were preceded by below-normal sea surface temperatures -- consistent with the La Nina phase of the El Nino- Southern Oscillation.The authors cite other research showing that the La Nina pattern alters the migration, stopover time, fitness and interspecies mixing of migratory birds. These conditions could favor the kind of gene swapping or genetic reassortment that creates novel and therefore potentially more variations of the influenza virus."We know that pandemics arise from dramatic changes in the influenza genome. Our hypothesis is that La Nina sets the stage for these changes by reshuffling the mixing patterns of migratory birds, which are a major reservoir for influenza," says Shaman.Changes in migration not only alter the pattern of contact among bird species, they could also change the ways that birds come into contact with domestic animals like pigs. Gene-swapping between avian and pig influenza viruses was a factor in the 2009 swine flu pandemic.

SANTO DOMINGO, Sept. 30 (Xinhua) -- Haitian health authorities on Friday said the number of deaths caused by cholera increased to 6,435 in the Caribbean country since October 2010.The Haitian Health Ministry said the number of people infected with cholera almost reached half a million, although the ministry repeated the epidemic was decreasing.The report said 455,727 people had been treated due to cholera, and 242,205 had to be hospitalized.The western province of Artibonite suffered the plague most with 1,196 deaths. The southwest province of Nippes registered the smallest death toll of 181.Meanwhile, in the Haitian capital Port-au-Prince, 221 people have been killed since October 2010 when the epidemic first broke out in central Haiti.The epidemic is supposedly due to the spill of dregs from a Nepalese camp, which is part of the UN Stabilization Mission in Haiti (MINUSTAH).The Dominican Republic, a country neighboring the island country Haiti to the east, has also been suffering the disease since November 2010, which has killed at least 135 people there.

ACCRA, Dec. 1 (Xinhua) -- The Ghanaian government allayed the fears of many here on Thursday that it would provide funding for the treatment of persons living with HIV/AIDS in the country.Vice President John Dramani Mahama affirmed this when he addressed a ceremony to mark this year's World AIDS Day at Obuasi, near Kumasi, 270 km north of the capital Accra.Mahama said should the Global Fund pull out of supporting the country, the government would partner with development partners to raise the 5.8 million U. S. dollars needed yearly for the treatment of HIV/AIDS patients."Government will work together with the Ghana AIDS Commission (GAC) and donor partners to ensure that people living with HIV/ AIDS have access to antiretroviral drugs."The Presidency is with you, and whatever we will do to win the fight against HIV/AIDS shall be done," Mahama said.Ghana's HIV/AIDS infection rate, according to official figures, has dropped from 3 percent to the current 1.5 percent, albeit with pockets of higher rates of infection among some populations in the country.Mahama called for more innovativeness in mobilizing resources to avoid the danger of retrogression.Director-General of the GAC Angela El-Adas announced that the Ministry of Health had pledged 2.5 million Ghana cedis (1.66 million dollars) out of the 5.8 million dollars needed for next year.Meanwhile, in the capital, the Ghana Network of Persons Living with HIV and AIDS (NAP+ GHANA) joined persons living with HIV (PLHIV) globally on Thursday to commemorate this year's World AIDS Day."We stand united with our fellow PLHIV and the global HIV and AIDS community by fully supporting the vision of 'Getting to Zero', " Charity Owusu Danso, vice president of NAP+ Ghana, said in a message here.Established in 2005, NAP+GHANA is a network of member associations of persons living with HIV/AIDS in Ghana to represent the views, hopes and aspirations of PLHIV across the country."We are extremely worried. Everyday, we receive reports from PLHIV across the country that anti-retroviral drugs are out of stock or that hospitals or clinics won't give HIV treatment to new patients because there aren't even enough drugs for existing patients, " the statement said.
