He Jiankui, a young Chinese scientist known to his American colleagues as JK, dreamed of remaking humanity by exploiting the emergent technology of gene editing. He had academic polish, and an ...

Around 2018–19, there was not a bigger science and ethical story than the debate over heritable human genome editing (HHGE) and the scandal over the “CRISPR babies.” The scientist, He Jiankui, who ...

Gene editing has just started to fulfill its promise as a therapeutic modality. Further progress depends on making gene editing therapies more relevant to more patients. This was the theme of a recent ...

However, traditional gene delivery methods, such as Agrobacterium-mediated transformation and gene guns, are often slow, inefficient, and can damage plant tissues. These highlight the need for more ...
