Malaria parasite ticks to its own internal clock
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.

Blood test a potential new tool for controlling infections
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
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
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
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%
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
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
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
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.

Deadliest malaria strain protects itself from the immune system
The parasite causing the most severe form of human malaria uses proteins to make red blood cells sticky, making it harder for the immune system to destroy it and leading to potentially fatal blood clots. New research has identified how the parasite may control this process.

Stuttering DNA orchestrates the start of the mosquito's life
There are large parts of the DNA that are not used for making proteins. This is called 'junk DNA', because its function remained unclear for a long time. However, a certain type of junk DNA that is found in mosquitoes and which repeats itself dozens of times, known as 'satellite DNA', has now been shown to play an essential role in the early development of mosquito embryos.

Is your coffee contributing to malaria risk?
Researchers estimate 20% of the malaria risk in deforestation hot spots is driven by the international trade of exports including: coffee, timber, soybean, cocoa, wood products, palm oil, tobacco, beef and cotton. The results of the study can be used for more demand-side approaches to mitigating malaria incidence by focusing on regulating malaria-impacted global supply chains.

Novel compound sparks new malaria treatment hope
A novel class of antimalarial compounds that can effectively kill malaria parasites has been developed. In preclinical testing, the compounds were effective against different species of malaria parasites, including the deadly Plasmodium falciparum, and at multiple stages of the parasite lifecycle. The compounds could overcome existing issues of parasite drug resistance. The researchers hope that drugs based on these early compounds will soon enter phase 1 clinical trials.

How the malaria parasite grows and multiplies
Scientists have made a major breakthrough in understanding how the parasite that causes malaria is able to multiply at such an alarming rate, which could be a vital clue in discovering how it has evolved, and how it can be stopped. For the first time, scientists have shown how certain molecules play an essential role in the rapid reproduction of parasite cells, which cause this deadly disease.
