New Way To Fight Mosquitoes.
Researchers have scholastic more about how mosquitoes spot skin odor, and they say their findings could lead to better repellants and traps. Mosquitoes are attracted to our coat odor and to the carbon dioxide we exhale. Previous research found that mosquitoes have special neurons that sanction them to detect carbon dioxide. Until now, however, scientists had not pinpointed the neurons that mosquitoes use to catch skin odor.
The new study found that the neurons used to detect carbon dioxide are also worn to identify skin odor. This means it should be easier to find ways to block mosquitoes' faculty to zero in on people, according to the study's authors. The findings appeared in the Dec 5, 2013 culmination of the journal Cell.

Mosquito Bite Waiting To Happen
Mosquito Bite Waiting To Happen.
Some family who fell target to a 2009-2010 outbreak of dengue fever in Florida carried a particular viral strain that they did not convey into the country from a recent trip abroad, according to a fresh genetic analysis conducted by the US Centers for Disease Control and Prevention. To date, most cases of dengue fever on American blacken have typically complicated travelers who "import" the painful mosquito-borne disease after having been bitten elsewhere. But though the bug cannot move from person to person, mosquitoes are able to pick up dengue from infected patients and, in turn, spreading the disease among a local populace.
The CDC's viral fingerprinting of Key West, FL, dengue patients therefore raises the specter that a cancer more commonly found in parts of Africa, the Caribbean, South America and Asia might be gaining gripping power among North American mosquito populations. "Florida has the mosquitoes that mail dengue and the climate to sustain these mosquitoes all year around," cautioned look lead author Jorge Munoz-Jordan. "So, there is potential for the dengue virus to be transmitted locally, and cause dengue outbreaks dig the ones we saw in Key West in 2009 and 2010".
And "Every year more countries annex another one of the dengue virus subtypes to their lists of locally transmitted viruses, and this could be the action with Florida," said Munoz-Jordan, chief of CDC's molecular diagnostics labour in the dengue branch of the division of vector-borne disease. He and his colleagues come in their findings in the April issue of CDC's Emerging Infectious Diseases.
Dengue fever is the most widespread mosquito-borne viral infirmity in the world, now found in roughly 100 countries, the study authors noted. That said, until the 2009-2010 southern Florida outbreak, the United States had remained basically dengue-free for more than half a century.
Ultimately, 93 patients in the Key West enclosure solely were diagnosed with the disorder during the outbreak, which seemingly ended in 2010, with no new cases reported in 2011. But the deficit of later cases does not give experts much comfort. The reason: 75 percent of infected patients show no symptoms, and the open-handed "house mosquito" population in the region remains a disease-transmitting disaster waiting to happen.
