A new advance could make it easier to study the placenta, and its role in pregnancy, miscarriage, and preeclampsia, say researchers.

Is BPA-free plastic safe? New research with mice suggests the alternative chemical, BPS, also poses risks.

The placenta acts as a gatekeeper during pregnancy, but a study that shows how RSV can infect the fetus suggests it's not as impenetrable as once thought.

A new technique that isolates trophoblast cells—placental cells that carry the complete fetal genome—could offer an alternative to more invasive tests.

A new discovery could lead to safer and more effective maternal vaccines, which protect pregnant women and their newborns from dangerous infections.

"…the placenta could actually help the mother's brain adapt to changing conditions during pregnancy to maintain a harmonious environment."

A new "placenta on a chip" allows researchers to see what compounds pass from mother to fetus.

Two proteins could be key to deciphering how pluripotent cells are born, which may one day lead to new ways of using stem cells to keep people healthy.
