    Doctors at Children's Hospital of Philadelphia have developed a new artificial womb that could benefit the tens of thousands of critically preterm (younger than 26 weeks) births in the US each year. According to a new paper published in the journal Nature Communications, the research physicians successfully kept fetal lambs alive inside a "uterus-like" plastic sack for up to four weeks -- longer than any similar device before it.
