Repurposed anti-malarial compounds kill diarrheal parasite, study finds
A class of compounds used for malaria treatment also kill the intestinal parasite Cryptosporidium, a leading cause of diarrheal disease and death in children that has no cure, a multi-institution collaboration of researchers found in a new study.

CRISPR-based malaria testing on-the-fly
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
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
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
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
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.

Mosquito immune system mapped to help fight malaria
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
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
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
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
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.

Tracking the spread of mosquito insecticide resistance across Africa
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.

Volcanic glass spray shows promise in controlling mosquitoes
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.
