New tool mimics human skin to allow detailed study of mosquito biting

Science Daily - September 23, 2020 - 16:46
Scientists have developed a tool for studying the biting behavior of common pathogen-carrying mosquitoes.

CRISPR-based malaria testing on-the-fly

Science Daily - September 21, 2020 - 19:26
A multi-disciplinary research collaboration created a field-applicable, ultrasensitive diagnostic assay that specifically detects DNA sequences from all Plasmodium species in symptomatic and asymptomatic malaria. The new malaria diagnostic method combines an optimized 10-minute rapid sample preparation protocol with the CRISPR-based SHERLOCK system to enable highly specific and sensitive Plasmodium detection in another 60 minutes in simple reporter devices.

How Dantu blood group protects against malaria, and how all humans could benefit

Science Daily - September 16, 2020 - 15:35
The secret of how the Dantu genetic blood variant helps to protect against malaria has been revealed for the first time. The team found that red blood cells in people with the rare Dantu blood variant have a higher surface tension that prevents them from being invaded by the world's deadliest malaria parasite, Plasmodium falciparum.

COVID-19 virus uses heparan sulfate to get inside cells

Science Daily - September 15, 2020 - 19:24
Researchers discovered that the SARS-CoV-2 virus can't grab hold of cell receptor ACE2 without a carbohydrate called heparan sulfate, which is also found on lung cell surfaces -- disrupting that interaction with a repurposed drug may help treat COVID-19.

Rising temperatures could shift US West Nile virus transmission

Science Daily - September 15, 2020 - 14:59
West Nile virus spreads most efficiently in the US at temperatures between 24-25 degrees Celsius (75.2-77 degrees Fahrenheit), a new study shows.

Human activities promote disease-spreading mosquitoes; more study needed for prevention

Science Daily - September 14, 2020 - 21:29
Disease-spreading mosquitoes may be more likely to occupy areas impacted by human activities like pesticide use and habitat destruction, than they are areas less disturbed by humans, a recent study found.

New malaria transmission patterns emerge in Africa

Science Daily - August 28, 2020 - 12:10
An international study reveals how future climate change could affect malaria transmission in Africa over the next century.

Mosquito immune system mapped to help fight malaria

Science Daily - August 27, 2020 - 18:12
Scientists have created the first cell atlas of mosquito immune cells, to understand how mosquitoes fight malaria and other infections. Researchers discovered new types of mosquito immune cells, including a rare cell type that could be involved in limiting malaria infection. The findings offer opportunities for uncovering novel ways to prevent mosquitoes from spreading the malaria parasite to humans and break the chain of malaria transmission.

Study explores the association of malaria, HIV with anemia during pregnancy

Science Daily - August 14, 2020 - 17:10
Pregnant women from sub-Saharan Africa with malaria and human immunodeficiency virus (HIV) have a higher prevalence of anemia than pregnant women without infections, according to researchers. The findings may have implications for reducing the risk of death in pregnant women and preventing low birth weights and neurocognitive impairment in their children as a result of anemia.

Malaria discovery could expedite antiviral treatment for COVID-19

Science Daily - August 11, 2020 - 16:01
New research into malaria suggests targeting enzymes from the human host, rather than from the pathogen itself, could offer effective treatment for a range of infectious diseases, including COVID-19.

New set of channels connecting malaria parasite and blood cells

Science Daily - July 30, 2020 - 13:26
Researchers have discovered another set of pore-like holes, or channels, traversing the membrane-bound sac that encloses the deadliest malaria parasite as it infects red blood cells. The channels enable the transport of lipids -- fat-like molecules -- between the blood cell and parasite, Plasmodium falciparum. The parasite draws lipids from the cell to sustain its growth and may also secrete other types of lipids to hijack cell functions to meet its needs.

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.
