High dosages of trial malaria vaccine produce promising results

By - August 13, 2013 1 Picture
A vaccine against malaria currently being developed in the US offers new hope to fight the infectious disease that enters the body through a mosquito bite. According to the World Health Organization, malaria killed 660,000 people in 2010. The intravenous vaccine currently being developed by Sanaria and the National Institute of Allergy and Infectious Diseases (NIAID) has produced promising results in volunteers who received a high dose the vaccine.

NanoMal's hand-held blood analyzer targets drug treatments for malaria

By - December 27, 2012 4 Pictures
A small company in the U.K. is developing an affordable, hand-held device that will not only diagnose malaria in the field, but will also read DNA markers that suggest which antimalarial drugs will be most effective for treatment. If fielded, such a device could help alleviate the 200+ million cases of malaria per year, as well as prevent some of the nearly one million deaths associated with malarial illness. Read More

LG mosquito-repelling air conditioner aims to help reduce malaria cases in Africa

By - November 22, 2012 2 Pictures
While promising vaccines and genetically-engineered mosquitoes are providing hope in the fight against malaria, it currently remains a major and potentially life-threatening problem in tropical and subtropical regions around the world. These regions are also hot and sticky, making LG's introduction of an air conditioner that it claims actively repels mosquitoes as it keeps the house cool a seemingly obvious blending of technologies.

Genetically-engineered mosquitoes can't transmit malaria

By - June 13, 2012 1 Picture
Last year, Prof. Anthony James announced that he and his colleagues had genetically altered Aedes aegypti mosquitoes in a fashion that could drastically reduce their populations. In a nutshell, the altered genes cause the female mosquitoes to be born without wings – this makes it rather difficult for them to go foraging for blood, and turns them into easy prey for almost any predator. The non-biting males are born with wings, and subsequently go off and mate with unmodified females, passing the modified genes along to their offspring. Now, James has done some more genetic engineering, to create mosquitoes that can’t spread malaria. Read More

Lab-grown human blood vessels could help study diseases, grow tissues for transplant

By - June 1, 2012 3 Pictures
A team of bioengineers at the University of Washington has developed the first structure for growing small human blood vessels in the laboratory. The vessels behave remarkably like those in a living human and offer a better and much more modular approach to studying blood-related diseases, testing drugs and, one day, growing human tissues for transplant.

Chemically altered osteoporosis drug kills malaria parasite in mice

By - March 1, 2012 5 Pictures
With malaria still responsible for millions of untimely deaths in more than 90 countries each year, the search for effective antimalarial drugs, vaccines and mosquito repellents continues to heat up. Recently, researchers at the University of Illinois (UI), led by chemistry professor Eric Oldfield, found that a chemically-altered form of a commonly prescribed osteoporosis drug can easily enter red blood cells and dispatch malaria parasites without harming the host (in this case, a mouse). That's potentially huge news for the countless thousands who continue to suffer from this recurrent, debilitating and all-too-often fatal disease. Read More

Light barrier used to repel mosquitoes

By - November 13, 2011 1 Picture
You're in the middle of a great chat with friends on a warm summer night, and then "ouch" a mosquito interrupts your conversation with a bite on your forearm. Experimental physicist Szabolcs Marka hopes to make this occurrence a thing of the past, but in this case it's not aerosol spray or roll-on-repellant keeping the bugs at bay, it's a wall of light.

Light used to quickly identify misshapen red blood cells

By - November 1, 2011 1 Picture
Ordinarily, red blood cells should look like a disc with a medium-sized dimple on the top and bottom. If that dimple is either too large or too small, it can indicate the presence of a disease such as sickle cell anemia or malaria. Pathologists traditionally have had to examine blood samples under a microscope, manually looking for these misshapen cells. A new technique developed at the University of Illinois at Urbana-Champaign, however, uses light to automatically detect such cells within seconds. Read More

Mosquito trap targets females laying their eggs

By - December 24, 2010 2 Pictures
After malaria, dengue fever is the most serious mosquito-borne disease in the world. In an effort to curb its spread, researchers from New Orleans’ Tulane University School of Public Health and Tropical Medicine have developed mosquito traps that attract and kill egg-bearing females. Using a US$4.6 million grant from The Bill & Melinda Gates Foundation, the scientists plan to distribute 10,000 of the traps in Peru’s Iquitos region, an area known for dengue fever. Read More
