The last time this summit convened in 2018, the world was shocked to hear a scientist had created the first gene-edited babies. He was condemned, but gene-editing has continued, with some success.

Biologists say newly efficient and accurate gene sequencing techniques have allowed them to fairly quickly detail full genomes and find overlooked genes in a broad range of 25 important species.
