The authors have requested a retraction of a paper that found people with the CCR5 Δ32 variant are more likely to die sooner.

Those with two copies of the Δ32 allele in the CCR5 gene are 21 percent more likely to die by age 76, although it’s not clear why.

The “London patient” may represent the second person cured of the infection by a cell transplant.

He Jiankui could face charges after an investigation finds he used techniques prohibited in China to edit the genes of twin girls.

2018 closed with hubbub surrounding the purported birth of babies whose genomes had been edited using CRISPR. What will 2019 hold for CRISPR’s use in humans?

Despite a premature and ethically sketchy claim of genome editing in twin girls, an outright prohibition could blunt promising, responsible progress.

He Jiankui, who reportedly edited the genomes of two babies already, broke the news at a conference in Hong Kong.

The college has opened an investigation into Michael Deem’s involvement.

He Jiankui says he has successfully used CRISPR-Cas9 to tweak the genes of twins born earlier this month. Some independent experts are dubious.
