Malaria causes an estimated 500 million clinical cases worldwide with symptoms ranging from headache, high fevers and nausea to more than 1 million deaths annually.
“Malaria has had a major effect on the evolution of our species. Mutations occurring in our genome that have helped us survive malaria have been selected for over tens of 1,000s of years of co-existing with this parasite.
Understanding how these mutations make us more resistant to malaria can help us design innovative new strategies to prevent or treat severe malaria in places such as sub-Saharan Africa,” says researcher Kevin Kain, a Professor out of the Department of Medicine at U of T and one of the lead researchers on the project. “Our research shows that people who have an enzyme deficiency or those who carry the gene trait for this deficiency may be protected from severe and fatal malaria.”
The team headed by Dr. Kain and which included researchers from McGill University found that a deficiency in an enzyme called pyruvate kinase, which is required for energy production in the body, provides protection against malaria infection.
The findings could lead to the design of new novel therapies to treat and prevent severe and fatal malaria through enhancing the body’s protective pathways instead of inundating the body with drugs. The study was funded by the Canadian Institutes of Health Research (CIHR) Team grant in malaria.
The study findings were published in the April 24th issue of New England Journal of Medicine.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
