Mosquito borne diseases like malaria and dengue are still rampant and have posed a great challenge to mankind. We have lost several lives in our war against mosquitoes, and scramble new ways to fight them. Now, researchers are working to genetically engineer the genes of mosquitoes using the technique of RNA interference, where an RNA is artificially inserted to disturb the normal functions of mosquito cells, thereby killing them in the process. This process, they claim, is environmentally friendly and most effective compared to existing strategies.
