Mosquito Repellant Could Be Frightening For Mosquitoes!
2012-02-28 04:08:12

[ Watch the Video ] Repellant overwhelms their odor sensors, scaring them away In a small, narrow, temperature-controlled lab room at Vanderbilt University live some of the most deadly and dangerous animals in the world. "These are Anopheles mosquitoes that still think that they're in Central Africa. We won't tell them any different," says Laurence Zwiebel, professor of molecular biology and pharmacology. Anopheles gambiae mosquitoes can be killers. In warmer climates, the...

Squirrels and raccoons will give up food to avoid ticks Here´s a riddle: What´s the difference between a tick and a lion? The answer used to be that a tick is a parasite and the lion is a predator. But now those definitions don´t seem as secure as they once did. A tick also hunts its prey, following vapor trails of carbon dioxide, and consumes host tissues (blood is considered a tissue), so at least in terms of its interactions with other creatures, it is like a lion...

A Battle Of The Vampires, 20 Million Years Ago
2012-02-04 04:33:28

They are tiny, ugly, disease-carrying little blood-suckers that most people have never seen or heard of, but a new discovery in a one-of-a-kind fossil shows that “bat flies” have been doing their noxious business with bats for at least 20 million years. For bats, that´s a long time to deal with a parasite doing its best vampire impression. Maybe it is nature´s revenge on the vampire bat, an aggressive blood consumer in its own right that will feed on anything from...

As mosquito-borne viral diseases like West Nile fever, dengue fever, and chikungunya fever spread rapidly around the globe, scientists at Virginia Tech are working to understand the mosquito's immune system and how the viral pathogens that cause these diseases are able to overcome it to be transmitted to human and animal hosts. In nearly every part of the world, humans and animals experience high levels of morbidity and mortality after being bitten by mosquitoes infected with viruses. More...

Lyme disease is the most commonly reported vector-borne disease in the United States, with the majority of cases occurring in the Northeast. It has been three decades since the agent of the disease, the spirochete Borrelia burgdorferi, and the ticks that vector it were identified. However, the number of Lyme disease cases have steadily increased. In a new article appearing in the forthcoming issuue of the Journal of Medical Entomology called "What Do We Need to Know About Disease Ecology...

Only Few Seabird Species Contract Avian Malaria
2011-12-13 04:02:07

Climate differences have less impact on the transmission of blood parasites than expected Seabirds often live in large colonies in very confined spaces. Parasites, such as fleas and ticks, take advantage of this ideal habitat with its rich supply of nutrition. As a result, they can transmit blood parasites like avian malaria to the birds. Scientists from the Max Planck Institute for Ornithology in Radolfzell and a team of international colleagues have investigated whether this affects all...

Image 1 - Which Came First? Humans Or Malaria?

Malaria Revealed As Ancient, Adaptive And Persistent Foe One of the most comprehensive analyses yet done of the ancient history of insect-borne disease concludes for the first time that malaria is not only native to the New World, but it has been present long before humans existed and has evolved through birds and monkeys. The findings, presented in a recent issue of American Entomologist by researchers from Oregon State University, are based on the study of insect specimens preserved...

New research published in the Journal of Leukocyte Biology suggests that salivary components from a Leishmania vector play a relevant and direct role on neutrophils, which influence parasite burden For millions of people who live under the constant threat of Leishmania infection, a new discovery by Brazilian scientists may lead to new breakthroughs, preventing these parasites from taking hold in the body or reducing the severity of infections once they occur. In a new report appearing in...

In dengue-endemic areas such as South-East Asia, in contrast to conventional thinking, rural areas rather than cities may bear the highest burden of dengue fever–a viral infection that causes sudden high fever, severe headache, and muscle and joint pains, and can lead to a life-threatening condition, dengue hemorrhagic fever. In a study led by Wolf-Peter Schmidt from the Nagasaki Institute of Tropical Medicine, Japan, and published in this week's PLoS Medicine, the authors analyzed a...

The Deer Fly (Chrysops spp.), also known as the "yellow fly", is a fly of the family Tabanidae that can be a pest to cattle, horses, and humans. It is often found in damp environments, such as wetlands or forests. It lays clusters of shiny black eggs on the leaves of small plants by water. The aquatic larvae feed on small insects and pupate in the mud at the edge of the water. The Deer Fly is often considered a horse-fly. A distinguishing characteristic is its patterned gold or green eyes....

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
