Every year, millions of babies are born before they are fully developed. Many of them die because they are not yet able to survive outside their mother. An estimated one million children worldwide die each year from problems resulting from being born too early, a condition called preterm birth. Now, researchers say they have developed an artificial womb that kept alive preterm baby sheep. They say the artificial womb acts like a uterus the female organ where sheep, babies and other creatures develop before they are born. The findings were published in the journal Nature Communications.
