Entomologists offer new hope for controlling malaria
Entomologists are bringing new hope of preventing malaria in tropical villages. Research published in the new issue of the Royal Entomological Society journal Medical & Veterinary Entomology could significantly improve the effectiveness of insecticide-treated mosquito nets. One paper (Guillet et al, Medical & Veterinary Entomology, 15(1),... view more... (2001-03-07)
New malaria vector species discovered in Africa
Malaria affects around 600 million people in the world and leads to an annual death toll of over 2 million. It is the world's most widespread parasitic disease. It is caused by Plasmodium falciparum, a pathogen transmitted to humans by a mosquito. In Africa, where malaria is endemic, mosquitoes of the Anopheles genus are the only vectors of the... view more... (2004-09-16)
Recent, rapid climate change is driving evolution of animal species
Rapid climate changes over the past several decades have led to heritable, genetic changes in animals as diverse as squirrels, birds and mosquitoes, according to University of Oregon evolutionary geneticists. view more (2006-06-09)
Malaria Parasites Develop in Lymph Nodes
In the first quantitative, real-time imaging study of the travels of the malaria parasite Plasmodium through mammalian tissue, researchers at the Pasteur Institute in Paris found the parasites developing in an unexpected place: the lymph nodes. view more (2006-01-23)
NIAID experts see dengue as potential threat to US public health
A disease most Americans have never heard of could soon become more prevalent if dengue, a flu-like illness that can turn deadly, continues to expand into temperate climates and increase in severity, according to a new commentary by Anthony S. Fauci, M.D., director of the National Institute of Allergy and Infectious Diseases (NIAID), part of the... view more... (2008-01-09)
Parasitic tropical diseases in the Americas, a legacy of slavery, can be eliminated
Although it has been speculated for more than a century that the slave trade was responsible for bringing many tropical diseases to the Americas, only recently has convincing evidence shown that lymphatic filariasis (elephantiasis), schistosomiasis, and onchocerciasis (river blindness) originated in this way. view more (2007-11-07)
Ethics of research involving animals
The Nuffield Council on Bioethics today announced a new Working Party to consider the ethics of research involving animals. There is considerable discomfort about the use of animals in research, but also a widespread acceptance of the need to do more medical research, which currently involves the use of animals. "We believe there is a need... view more... (2003-03-17)
What gives us sunburn protects crayfish against bacteria
The production of melanin gives us sunburns, but it also helps invertebrate animals to encapsulate attacking fungi and parasites. view more (2007-09-25)
Mosquito genes explain response to climate change
University of Oregon researchers studying mosquitoes have produced the first chromosomal map that shows regions of chromosomes that activate - and are apparently evolving - in animals in response to climate change. view more (2007-04-24)
Researchers block the transmission of malaria in animal tests
By disrupting the potassium channel of the malaria parasite, a team of researchers has been able to prevent the malaria parasites from forming in mosquitoes and has thereby broken the cycle of infection during recent animal tests. view more (2008-06-10)
Researchers discover how malaria parasite disperses from red blood cells
Researchers at the National Institute of Child Health and Human Development have determined the sequence in which the malaria parasite disperses from the red blood cells it infects. view more (2005-09-20)
Vaccine puts blood-sucking ticks off their food
Ticks spread a greater variety of diseases than any other blood-feeding creature, including mosquitoes. Now scientists are developing vaccines that prevent ticks from digesting the blood of their animal or human victim, according to research presented today (Monday 08 April 2002) at the spring meeting of the Society for General Microbiology at the... view more...

Detecting poisons in nectar is an odour-ous task for honeybees
Though many spring flowers have bright advertisements offering sweet rewards to honeybees, some common flowers have not-so-sweet or even toxic nectars. view more (2007-04-02)
DDT In Mothers' Blood Predicts Delays In Daughters' Pregnancies (p 2205)
A research letter in this week's issue of THE LANCET reports on the effect of the pesticide DDT and its by-product, DDE, on female reproductive capability. DDT was banned from use in the USA three decades ago after its toxic effects on environment, animal and human health (via the food chain) were identified. DDT is still used in some... view more...

Biologists visualize protein interaction that may initiate viral infection
Biologists at Purdue University have taken a "snapshot" of a Velcro-like protein on a cell's surface just after it attached to the dengue virus, a linkup thought to initiate the early stages of infection. view more (2006-02-10)
Jeepers Creepers! Climate Change Threatens Endangered Honeycreepers
As climate change causes temperatures to increase in Hawaii's mountains, deadly non-native bird diseases will likely also creep up the mountains, invading most of the last disease-free refuges for honeycreepers - a group of endangered and remarkable birds. view more (2009-05-27)
Natural born repellents
Are you a mosquito magnet? If you are, it's not your sweet smelling blood that attracts them, scientists say - you simply lack a chemical that some humans produce that masks your attractiveness to bugs, tricking them into thinking that you are not a suitable host. "For the first time, we can identify exactly which chemicals the insects... view more... (2004-03-26)
Global program to eliminate elephantiasis has early success in Egypt
Organizers of a 20-year global effort to eliminate a parasitic infection that is a leading cause of disability have an early victory to savor: a five-year Egyptian elimination campaign has mostly succeeded. Infection with the parasites, threadlike filarial worms, can lead to the dramatic, disfiguring swelling known as elephantiasis. view more (2006-03-24)
'Dodgy dossier' partly to blame for failure of war against malaria in the tropics
The war against malaria in tropical countries was fought and lost in the 20th Century on the basis of faulty intelligence, a 'dodgy dossier' which argued that the same methods used to tackle the disease in temperate countries would also work in the tropics. view more (2008-09-11)
Common pesticide may reduce fertility in women
Methoxychlor (MXC), a common insect pesticide used on food crops, may interfere with proper development and function of the reproductive tract, leading to reduced fertility in women, researchers at Yale School of Medicine write in the August issue of Endocrinology. view more (2005-09-13)
