Cenix BioScience GmbH, a leading specialist in advanced RNA interference (RNAi)-based research services, Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), a leading RNAi therapeutics company, and the Lisbon-based biomedical research centre Instituto de Medicina Molecular (IMM), have announced the publication of their collaborative study in Cell Host & Microbe, describing the discovery and in vivo validation of scavenger receptor BI (SR-BI), a major regulator of cholesterol uptake by the liver, as a critical host factor for malaria infection. 
DEET's Not Sweet to Mosquitoes, Groundbreaking Research Shows

Spray yourself with a DEET-based insect repellent and the mosquitoes will leave you alone. But why? They flee because of their intense dislike for the smell of the chemical repellent and not because DEET jams their sense of smell, report researchers at the University of California, Davis.

It seems like common sense: Reduce insect populations, and insect-borne diseases will decline as well. But a new study of dengue, a viral disease transmitted by Aedes mosquitoes, suggests the opposite. Controlling mosquitoes may result in more cases of dengue hemorrhagic fever (DHF), a rare and sometimes fatal disease caused by the virus.
Researchers think that tens of millions of people in the tropics become infected with the dengue virus each year. The pathogen can spur dengue fever, which is marked by agonizing muscle and joint pains but is rarely fatal

Battling malaria for millennia helped Africans build barriers against the parasite that causes it, but that defense has proven to be a double-edged sword for HIV infection. One protein, the Duffy antigen receptor for cytokines, protects against malaria by making the individual more susceptible to contracting HIV. However, those same individuals do live longer once infected.
New mesh gives net gains against mosquitoes

Mosquitoes can carry many blood-borne diseases, like malaria and yellow fever. This study follows the introduction of: bed nets designed to stop mosquitoes in their tracks, which are undergoing large-scale trials in India and Tanzania.
Two Resistance Genes for the Price of One--Ideal?

It seems like a no-brainer, even for mosquitoes: Why be resistant to one pesticide when you can be resistant to two? In practice, however, such adaptations weaken insects in other ways, so more might not be a good thing.

How many people contract malaria? Which places are hardest hit? Has incidence or mortality been cut much in the past decades? Which has been more successful: prevention or treatment? How do you prevent malaria infections? What about making genetically modified mosquitoes that can't carry the disease?

Thousands of Paraguayans blocked highways and banged on the doors of health centers on Tuesday, demanding vaccines after four people died in the first outbreak of yellow fever in 30 years in this South American nation.
Researchers take whole-parasite road to a malaria vaccine

Most vaccines are made from extracted or re-created proteins, but these guys are trying the whole plasmodium vivax, killed with radiation. So far, the process seems too cumbersome to be practical, but unlike sole-protein vaccines, it doesn't leave people collapsing in the middle of a conference.
So far it looks pretty tough. They have to remove the salivary glands by hand and it takes the whole team an hour to do just eighty mosquitoes.
On a more amusing note, you know how they kill the mosquitoes without killing the parasites? Ethanol. Drink up, kiddo.
Mutation Fired Outbreak of Deadly Tropical Virus

What a difference a nucleotide makes. A simple change in the genetic sequence of the chikungunya virus may have triggered a massive outbreak of the deadly tropical disease on an island in the Indian Ocean in 2005 and 2006. The mutation made it easier for the virus to reproduce inside the mosquitoes that transmit it to humans, researchers report in the current issue of PLOS One.
Malaria-resistant mosquitoes battle disease with 'molecular warhead'
bianjie submitted, created time 1 year 4 months (www.biologynews.net)
A team led by UT Southwestern Medical Center researchers has discovered why some mosquitoes are resistant to malaria, a finding that may one day help fight a disease that afflicts and kills millions of people.
