The mystery of the less deadly mosquito nets

Science Daily - July 28, 2020 - 15:35
Research shows that insecticide-treated mosquito nets, the mainstay in the global battle against malaria, are not providing the protection they once did - and scientists say that's a cause for serious concern in tropical and subtropical countries around the globe.

Getting a grasp on India's malaria burden

Science Daily - July 3, 2020 - 13:49
A new approach could illuminate a critical stage in the life cycle of one of the most common malaria parasites.

Tracking the spread of mosquito insecticide resistance across Africa

Science Daily - June 25, 2020 - 18:07
In a step toward better control of the mosquitoes that transmit malaria, researchers have mapped the patterns of insecticide resistance in Anopheles gambiae mosquitoes across Africa. The new study found that resistance to five mainstream insecticides increased dramatically between 2005 and 2017.

First known case of a potentially deadly heart rhythm disturbance induced by chloroquine therapy for COVID-19 reported

Science Daily - June 18, 2020 - 16:02
Clinicians should carefully monitor patients treated with chloroquine therapy, particularly elderly women and others at higher risk for heart rhythm abnormalities, investigators caution in new article.

New discovery paves way for next generation malaria vaccine

Science Daily - June 16, 2020 - 14:08
New findings pave the way for a novel, next generation genetically attenuated parasite (GAP) vaccine against the deadliest form of malaria in humans.

New approach to reducing spread of mosquito-borne diseases

Science Daily - June 8, 2020 - 17:25
Researchers working in rural Kenya have identified the most productive breeding habitats for mosquitoes that spread a range of untreatable viruses. Their findings point to more effective health interventions that focus on the purpose of water-holding containers.

Volcanic glass spray shows promise in controlling mosquitoes

Science Daily - June 5, 2020 - 16:15
An indoor residual spray made by combining a type of volcanic glass with water showed effective control of mosquitoes that carry malaria, according to a new study. The findings could be useful in reducing disease-carrying mosquito populations - and the risk of malaria - in Africa.

Emerging viral diseases causing serious issues in west Africa

Science Daily - May 19, 2020 - 18:04
In a new study, researchers call attention to the emergence of mosquito-borne viral outbreaks in West Africa, such as dengue (DENV), chikungunya (CHIKV) and Zika (ZIKV) viruses.

Malaria parasite ticks to its own internal clock

Science Daily - May 14, 2020 - 18:35
Researchers have long known that all of the millions of malaria parasites within an infected person's body move through their cell cycle at the same time. They multiply in sync inside red blood cells, then burst out in unison every few days. But how the parasites keep time was unclear. Now, a study finds that malaria has its own internal clock that causes thousands of genes to ramp up and down at regular intervals.

Discovery of malaria parasite's clock could pave way to new treatments

Science Daily - May 14, 2020 - 18:35
The parasite that causes malaria has its own internal clock, explaining the disease's rhythmic fevers and opening new pathways for therapeutics.

Malaria vaccine: Could this 'ingredient' be the secret to success?

Science Daily - May 13, 2020 - 15:14
Researchers have identified a microscopic 'ingredient' that can be added to a malaria vaccine for efficient protection against the deadly pathogen.

Malaria mosquitoes eliminated in lab by creating all-male populations

Science Daily - May 12, 2020 - 17:44
A modification that creates more male offspring was able to eliminate populations of malaria mosquitoes in lab experiments.

Blood test a potential new tool for controlling infections

Science Daily - May 11, 2020 - 15:26
Researchers have developed a new approach to detecting a person's immunity to an infectious disease -- providing valuable details about whether and when a person was exposed to the infection. The test was developed for detecting recent exposure to malaria, but the research team are now working to adapt it to detect previous exposure to the coronavirus that causes COVID-19. By providing a detailed picture of when an infection spread in a community, the test offers new opportunities for improving infection control and elimination strategies -- particularly in lower income countries.

New computational method unravels single-cell data from multiple people

Science Daily - May 6, 2020 - 16:37
A new computational method for assigning the donor in single cell RNA sequencing experiments provides an accurate way to unravel data from a mixture of people. The Souporcell method could help study how genetic variants in different people affect which genes are expressed during infection or response to drugs, and help research into transplants, personalized medicine and malaria.

Malaria risk is highest in early evening

Science Daily - May 4, 2020 - 15:40
Wide-scale use of insecticide-treated bed nets has led to substantial declines in global incidences of malaria in recent years. As a result, mosquitoes have been shifting their biting times to earlier in the evening and later in the morning.

Designing drugs to combat drug-resistant malaria

Science Daily - April 30, 2020 - 21:09
For the first time, researchers have shown a key difference in the three-dimensional structures of a key metabolic enzyme in the parasite that causes malaria compared to its human counterpart.

Smart interventions reduce malaria transmission by 75%

Science Daily - April 27, 2020 - 14:25
Mass drug administration and vector control can help eliminate malaria. A vector refers to an organism that transmits infection, as mosquitoes infected with parasites transmit malaria to people.

Research reveals a new malaria vaccine candidate

Science Daily - April 22, 2020 - 17:29
In a study that could lead to a new vaccine against malaria, researchers have found antibodies that trigger a 'kill switch' in malarial cells, causing them to self-destruct.

Genetic variation not an obstacle to gene drive strategy to control mosquitoes

Science Daily - April 16, 2020 - 19:18
New research from entomologists clears a potential obstacle to using CRISPR-Cas9 'gene drive' technology to control mosquito-borne diseases such as malaria, dengue fever, yellow fever and Zika.

Low-cost imaging system poised to provide automatic mosquito tracking

Science Daily - April 15, 2020 - 21:14
Mosquito-transmitted diseases such as malaria, dengue and yellow fever are responsible for hundreds of thousands of deaths every year. A new low-cost imaging system could make it easier to track mosquito species that carry disease, enabling a more timely and targeted response.
