Shulamit Michaeli and colleagues describe a pathway in T. brucei parasites that they named SLS (SL-RNA silencing). Triggering this pathway shuts down the synthesis of a crucial RNA molecule, which halts the production of messenger RNAs and leads to the parasite’s death.
Inducing SLS could therefore be a novel way to eradicate parasites and prevent sleeping sickness - trypanosomiasis. The researchers also believe this could have implications for related parasites and diseases, such as Leishmania and leishmaniasis and Trypanosoma cruzi and Chagas disease.
Sleeping sickness affects humans and livestock, and is endemic in sub-Saharan Africa where it is estimated to affect as many as 70,000 people. Leishmaniasis is estimated to affect millions of individuals throughout the world, and can lead to skin lesions, tissue damage, fever, blindness and death.
Chagas disease affects 16-18 million people across the Americas, and can cause intestinal complications, neurological disorders, heart damage and death. Although drugs are available to treat these diseases, their use is hampered by toxicity and undesirable side effects, difficulties in administering treatment, an increase in drug resistance, and high costs.

Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...
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...
Nature does amazing things with limited design materials. Grass, for example, can support its own weight, resist strong wind loads, and recover after being...
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...
