Ziplock uterus on the horizon…

Scientists have been able to keep premature lambs alive for weeks using an artificial womb that looks like a plastic bag.

It provides everything the foetus needs to continue growing and maturing, including a nutrient-rich blood supply and a protective sac of amniotic fluid.

The approach might one day help premature human babies have a better chance of survival, experts hope.

Human trials may be possible in a few years, according to researchers.
