Milk—it’s the elixir of life, the one food all mammals need to survive. But not all milk is the same; every species has its own particular formula. At the National Zoo in Washington, D.C., one team of scientists is dedicated to studying all there is to know about the white gold. Working with specially trained mammals, these experts collect samples of milk from various species of animals to learn more about the origins of life. With samples spanning over 180 species, the lab is working on uncovering the many secrets of milk while also creating formulas for baby animals that cannot be naturally reared by their own mothers.
