An Anopheles gambiae mosquito feasts on a human.

May 16, 2013 Scientists used a Dutch woman's dirty stocking to learn that mosquitoes infected with malaria find humans hard to resist. Like a fungus that turns ants into zombies, the parasite seems to change the behavior of the mosquitoes for its own benefit.

Using Bacteria To Swat Malaria Inside Mosquitoes

More than a hundred different species of Anopheles mosquitoes can transmit malaria to people.

May 9, 2013 Infecting mosquitoes with a specific type of bacteria makes the insects resistant to malaria. Now scientists have figured out how to get the mosquitoes to pass the infections on to their offspring. If it can done reliably, it might help interrupt transmission of malaria to humans.

A New Way To Make The Most Powerful Malaria Drug

An extract of sweet wormwood has been used in China for thousands of years to treat malaria, but being able to make mass quantities of the extract has been elusive, until now.

April 10, 2013 The relatively scarce "sweet wormwood" plant has long been the only source of the herbal drug artemisinin. A new trick for making artemisinin in the lab should help even out supplies around the world, scientists say, and cut the cost of malaria treatment.

Mosquito Maven Takes Bites For Malaria Research

Chiara Andolina, a malaria researcher in Thailand, feeds her mosquito colony by letting the insects bite her right arm. These mosquitoes are picky and will dine only on live human blood.

January 2, 2013 A scientist in Thailand raises mosquito colonies so she can study a new malaria drug. The insects are quite spoiled — they'll eat only live human blood. So she feeds them "breakfast" each day from her right arm.

As Biodiversity Declines, Tropical Diseases Thrive

Mosquitoes like this one can carry the virus that causes dengue fever, which may become a bigger problem in some regions as biodiversity is lost.

December 29, 2012 Researchers argue that ecology has a pretty big say in whether disease rates increase or die down. They used a new field that blends economics and ecology called "macroecology" to figure out how biodiversity loss affected disease burden.

Killer Cocktails: Shaken With A Splash Of Malaria Drugs

Shaken with splash of malaria drug, please. The original James Bond martini is made with gin, vodka and Kina Lillet, a French aperitif wine flavored with a smidge of the anti-malaria drug quinine.

So if you're sipping a French aperitif or an absinth cocktail this holiday season, chances are you're also imbibing a bit of malaria history.

Fake Malaria Drugs Fuel Rise Of Drug-Resistant Disease

In rural areas of Myanmar, villagers can buy inexpensive packets of drugs, called Ya Chut, when they have malaria. But these local remedies often don't contain adequate amounts of malaria medicines.

December 19, 2012 Myanmar and other parts of Southeast Asia are awash with shoddy and phony malaria drugs. Some fakes are almost indistinguishable from authentic drugs. The counterfeits can be deadly for patients, but they also threaten to undermine major weapons against the disease.

December 18, 2012 Global deaths from malaria have dropped sharply in the past decade, thanks in part to powerful drugs called artemisinins. But on the border between Thailand and Myanmar, doctors are starting to see cracks in artemisinin's armor. The medicine is working more slowly, and sometimes not at all.

Global Fund Moves To Discontinue Project Subsidizing Malaria Drugs

A controversial pilot project reduced the cost of the most effective malaria drugs by giving manufacturers, such as Guilin Pharmaceutical in China, subsidies.

November 16, 2012 After months of debate, the Global Fund announced plans to wind down a controversial pilot project that subsidizes malaria drugs in Africa. Some health workers in the U.S. fault the decision, saying it doesn't address the major challenges of treating malaria in poor countries.

Signs Of Drug-Resistant Malaria Emerge In Vietnam And Myanmar

Health workers take a blood sample from an infant to test for the malaria at a clinic along the border between Thailand and Myanmar.

November 14, 2012 Southeast Asia is a hot spot for drug-resistant malaria. In the past few years, parasites in two regions have become less responsive to the last, best drug we have against malaria. Researchers report that this new type of drug resistance may be spreading to Vietnam and central Myanmar.

Malaria-Like Disease Follows Lyme's Path In New England

As white-tailed deer have returned to New England in the past century, they've brought with them tick-borne parasites that cause human diseases.

November 12, 2012 Although Lyme disease is the most common tick-borne infection in New England, researchers find that babesiosis, a disease that mimics malaria, is catching up. The swelling population of white-tailed deer and the ticks that feed on their blood may be why.

Experimental Malaria Vaccine Disappoints, But Work Continues

A mother dresses her baby after doctors examined him during the malaria vaccine trial at the Walter Reed Project Research Center in Kombewa in Western Kenya in October 2009.

November 9, 2012 An experimental vaccine for malaria reduces infants' risk of the disease by about a third. That's less than researchers had hoped for, given the vaccine's effectiveness in toddlers, but doctors say it's enough to prevent many high fevers, seizures and deaths in a lot of African children.

November 9, 2012 At health clinics along the Thai-Myanmar border, malaria is getting tougher to treat as resistance to medication grows. Doctors say it may be time to focus on eradicating malaria before the drugs lose potency.
