The latest weapon against premature deaths is this bag, with tubes that introduce nutrients, which has allowed a lamb to complete its last four weeks of gestation.

Our colleagues from Omicrono had one of the scientific advances of the week last night. Researchers at Children’s Hospital in Philadelphia, USA, have developed an artificial uterus.

A spectacular video shows this milestone. In it, a lamb extracted from its mother’s uterus between 15 and 17 weeks old spends the last four weeks of gestation in this device.

The artificial uterus is made up of a bag, whose fluid mimics the amniotic, and tubes that provide nutrients to this particular placenta. Details of the investigation appear in the journal Nature Communications.
