Cows, buffalo, goats and sheep provide most of the world’s milk today. But one day, people could be sipping milk from cockroaches, if some scientists get their way. Pacific beetle cockroach moms (molted shell of one of these roaches shown below) feed their developing young a milklike nutrient. Using crystallography on its proteins, chemists have shown that the roach milk is “three times more nutritious than cow’s milk and four times more nutritious than buffalo’s milk,” says biologist Barbara Stay of the University of Iowa in Iowa City. The researchers would like to see cockroach milk turned into a protein supplement to feed hungry people.
