科学家发现基因编辑可以阻止蚊虫传播疟疾,将寄生虫水平减少90%。 Scientists discover gene edit that could stop mosquitoes from spreading malaria, reducing parasite levels by 90%.

研究人员发现基因改变可以防止蚊子传播疟疾。 Researchers have found a genetic modification that could prevent mosquitoes from transmitting malaria. 通过利用CRISPR技术改变FREP1基因中的单一氨基酸,它们使蚊虫口腔腺中的感染性寄生虫的数量减少了约90%。 By using CRISPR technology to alter a single amino acid in the FREP1 gene, they reduced the number of infective parasites in mosquitoes' salivary glands by about 90%. 基因变化通过使用基因驱动的蚊子群迅速传播,可能导致疟疾传播大幅减少。 The genetic change was spread rapidly through a mosquito population using a gene drive, potentially leading to a significant reduction in malaria transmission. 这可以成为防治疟疾斗争中的一个重大步骤,疟疾每年影响数百万人。 This could be a major step in the fight against malaria, which affects millions annually.
