Genetically Modified Cows Produce Milk Akin To Human Milk
In a potential new step for genetically modified food, babies could someday drink human-like milk derived from herds of genetically modified dairy cows, which scientists say could supplement breast milk and replace baby formula. Scientists have created 300 cows that produce milk with some of the properties of human breast milk, including lysozyme, which fights bacteria and improves infants' immune systems in their first few days of life.
