Over the next three years, our primary objectives include expanding our portfolio of gene drives and antimalarial effectors, refining existing tools, and progressing toward gene drive field trials. (imperial.ac.uk)
Gene drives are a technology through which a few genetically engineered individuals are designed to intentionally push new genes through an entire population of a species in the wild. (cban.ca)
The United Nations Convention on Biological Diversity has not agreed to an international moratorium on gene drives but has agreed that strict risk assessment is needed as well as the consent of local communities and Indigenous peoples. (cban.ca)
Press Release - United Nations Hits the Breaks on Gene Drives , ETC Group and Friends of the Earth International, November 29, 2018. (cban.ca)
Acknowledgement of this challenge has led to theorizing various means to control or reverse gene drives, however these exist only as mathematical models and are accompanied by their own complex risks. (cban.ca)

Des spécimens ont été capturés dans 9 provinces pendant deux activités saisonnières en 2001-2002, identifiés morphologiquement et soumis à une PCR et à un séquençage direct. (who.int)
