Another controversial attempt of whether gene-modified people are possible.

His team collected more than 200 one-cell embryos and attempted to alter their DNA to install a gene that protects against HIV infection. The study, published two days ago in an obscure reproductive journal, was first spotted by reporters at Nature.
The scientists cautioned that they believe making actual genetically modified babies should be “strictly prohibited”—but perhaps only until the technology is perfected. “We believe that is necessary to keep developing and improving the technologies for precise genetic modification in humans,” Fan’s team said, since gene modification could “provide solutions for genetic diseases” and improve human health.
