Correction 14 January 2020: An earlier version of this story incorrectly stated that Li Ning’s team engineered goats to produce a human milk protein in their milk. In fact, the goats produced an earthworm enzyme. The earlier version also gave an incomplete citation for that work, and omitted the citation for the paper on cow-milk engineering.
