In a re-run of the GM wonder-crop revolution which promised weed-free fields growing pest-free crops, it looks like we're getting a GM wonder-pig revolution of disease-free herds (soon to be followed by flocks of GM wonder-hens and shoals of GM wonder-fish).
Scottish scientists have modified pig genes to "massively increase resistance and resilience to infection". The first targets are 'Porcine Reproductive and Respiratory Syndrome Virus' (PRRSV) which causes breathing problems and leads to still births and stunted offspring when sows are infected, and African Swine fever.
