Scientists have used a new gene-editing technique to create pigs that can keep their bodies warmer, burning more fat to produce leaner meat. Infrared pictures of 6-month-old pigs taken at zero, two, and four hours after cold exposure show that the pigs' thermoregulation was improved after insertion of the new gene. The modified pigs are on the right side of the images. Zheng et al. / PNAS hide caption
