RESEARCH | Molecular biology Researchers have captured, at near-atomic resolution, the trans-spliceosome, a molecular machine essential to the parasites behind sleeping sickness, Chagas' disease and leishmaniasis. It does not exist in this form in humans, which makes it a promising drug target. https://www.sciences.uliege.be/cms/c_13735307/en/researchers-reveal-snapshots-of-a-key-molecular-machine-in-tropical-parasites
