SYDNEY, May 27 (Xinhua) -- A toddler and a policeman have become the latest victims of a rare and potentially deadly mosquito-borne disease in Western Australia (WA), local media reported on Friday.The two-year-old child contracted Murray Valley encephalitis (MVE) in the Kimberley of WA and is now in Royal Darwin Hospital in a stable condition, according to Australian Associated Press (AAP).The 29-year-old police officer, who was recently contracted the disease at an Aboriginal community of WA, has emerged from a coma in a Perth hospital but is still unable to communicate.It is not known if the victims from WA's far north will fully recover.In April 2011, a man who had been traveling in WA's northwest became the first person in the state to die from the disease in three years.A 19-year-old Canadian tourist also died after contracting MVE while traveling through the Northern Territory earlier in May.A WA Health Department spokeswoman said nine West Australians had contracted MVE so far in 2011. Several people remain very ill in hospital, she said.

LOS ANGELES, April 29 (Xinhua) -- Clinical and teaching microbiology laboratories are linked with a nationwide salmonella outbreak in the United States that has killed one person and sickened dozens of others, health officials confirmed on Friday.Since August, about 73 people in 35 states have been sickened by salmonella bacteria, and some of those cases involve a strain of Salmonella typhimurium sold commercially to laboratories, officials from the Centers for Disease Control and Prevention (CDC) said in remarks published by msnbc.com.Illnesses have been tied to laboratories from Alaska to New York, with most reporting one or two cases. Five cases have been reported in Washington state and four in Minnesota.The first illness occurred late August and the most recent cases were reported March 8, according to the CDC.The patients include employees and students of the laboratories, as well as children in the homes of people who work or study at the labs.Patients ranged in age from less than one to 91, with a median age of 24, the CDC said.Cases that developed after March 19 may not yet be included in the total because of the lag time in assessing and reporting illness, said the report.CDC officials warned that bacteria used in the labs can be transmitted through contaminated lab coats, pens, notebooks, car keys and other items brought into the labs.The CDC is working with local and state health departments, the American Society for Microbiology and the Association of Public Health Laboratories to track the outbreak, the report said.Salmonella infections typically result in diarrhea, fever and abdominal cramps. They can be dangerous in very young children or people with compromised immune systems.

SAN FRANCISCO, April 7 (Xinhua) -- Google's Android will become the most popular smartphone operating system worldwide and will account for 49 percent of the market by 2012, IT research and advisory firm Gartner said Thursday.According to Gartner's projections, worldwide smartphone sales will reach 468 million units in 2011, a 57.7 percent increase from 2010.The company predicts that Apple's iOS will remain the second biggest platform worldwide through 2014 although its share will decrease slightly after 2011, on the assumption that "Apple will be interested in maintaining margins rather than pursuing market share by changing its pricing strategy."Microsoft's Windows, driven by its partnership with Nokia, is expected to move into the mid-tier by the end of 2012 and become the third largest in the worldwide ranking by 2013.Some analysts raised doubts on Gartner's forecasts, saying that its assumption on Apple's price strategy contradicts statements by Apple's chief operating officer Tim Cook and the cooperation between Nokia and Microsoft will not have that much of an impact on smartphone market share by 2012.

You can think of NASA's Discovery program as a sort of outer-space American Idol: every few years the agency invites scientists to propose unmanned planetary missions. The projects have to address some sort of fundamental science question, and (this is the tough part) they have to be relatively cheap to pull off — say, half a billion dollars or so. Then the proposals go through a grueling competition before judges who aren't as nasty as Simon Cowell but who are every bit as tough. The one left standing at the end gets the equivalent of a recording contract: NASA supplies the funding and the launch vehicle, and away the winner goes — to orbit Mercury, as the Messenger spacecraft is doing right now; or to rendezvous with a couple of asteroids, as the Dawn mission will start doing this July; or to smash into a comet on purpose, a feat achieved by Deep Impact in 2005, a mission not to be confused with the movie of the same name. Now it's time for the next contenders. NASA has just announced that the first round of the latest Discovery competition is over, with three entries out of 28 moving on to the finals. They are, in increasing distance from Earth: the Geophysical Monitoring Station (GEMS) lander, which would use seismometers to study the interior of Mars; the Comet Hopper, which would do just that, leaping from place to place across the surface of Comet 46P/Wirtanen to see how different parts of the tumbling body react to heating by the sun; and the Titan Mare Explorer (TiME), which would plop into a sea of liquid hydrocarbons on Saturn's moon Titan — the first oceangoing vessel ever to set sail on another world. If you had to come up with a theme that ties all three missions together, it would be "origins." The Titan explorer, for example, will be studying a place that — in a crude way, at least — resembles the early planet Earth at a time when life arose here. Titan, with a thick atmosphere and a bizarro-world form of weather featuring toxic winds and hydrocarbon rain, is home to a mix of complex chemistry, complete with organic molecules. The oceans provide a medium in which the molecules can move around and interact with each other. It's even conceivable, though clearly a long shot, that some form of microscopic life already exists on this frigid moon. The Mars lander, by contrast, would visit a place where the seas — plain water in this case — vanished long ago. But the mission of GEMS goes far deeper than that. By analyzing Marsquakes on the Red Planet, GEMS will try to get a handle on what the interior of Mars is like. Scientists don't currently know whether the planet's core is liquid, like Earth's, or solid, or some mushy consistency in between. It all depends on how efficiently Mars has cooled since it formed 4.5 billion years ago, and that depends in turn on the planet's internal structure. "That's the mission," says Bruce Banerdt, of NASA's Jet Propulsion Laboratory, the lead scientist for GEMS. "We want to understand how Mars was built." Along with sensitive seismographic equipment, GEMS will drill down about 20 ft. (6 m) with a thermometer-equipped probe, trying to figure out how quickly the temperature rises with depth. "That will let us extrapolate all the way down to the center," Banerdt says, "which will tell us how fast Mars is cooling."

LOS ANGELES, April 4 (Xinhua) -- A woman's breast milk cells may be used to predict cancer in future research, according to a study published by HealthDay News on Monday.In the study, researchers at the University of Massachusetts in Amherst collected breast milk from 271 women in the United States. All had either undergone a biopsy of the breast to check for cancer, or were scheduled for one.The researchers evaluated breast milk samples from the biopsied and non-biopsied breasts.The researchers first isolated potentially cancerous cells, known as epithelial cells, and then isolated DNA to look for signals that regulate tumor suppresser genes.In the next step, the researchers analyzed three genes among the many known to undergo a process called methylation in breast cancer. Methylation in a specific region of a gene can inhibit or suppress the expression of a gene.For one gene, SFRP1, the average methylation was higher in the biopsied breast, the study found.Among the women whose biopsies detected cancer, average methylation of the RASSF1 gene in the biopsied breast was considerably higher compared to the non-biopsied breast.Among the women whose biopsies detected cancer, average methylation of the RASSF1 gene in the biopsied breast was considerably higher compared to the non-biopsied breast."It looks as if we can use the cells from breast milk to assess breast cancer risk," said Dr. Kathleen Arcaro, an associate professor of veterinary and animal sciences at the university.It's too soon, however, to assess the cancer detection rate associated with breast milk cell examination, she said."We can't say at this point for two reasons," she said. "One is, we need long-term follow-up. And the second really important reason is, we need to sample a larger panel of genes."Arcaro is to present her findings later Monday at the annual meeting of the American Association for Cancer Research in Orlando, Florida, according to HealthDay News.
