Researchers Create 3-D Placenta to Uncover more Information about Zika

WASHINGTON (AP) — Researchers have created a cellular model of the human placenta to help uncover how infections like the Zika virus might pass from a mother to her unborn child.

A virologist at the University of Pittsburgh says her team created a 3-D model of the placenta's outer boundary to try to learn how some infections sneak past and harm the fetus, and why it happens in some pregnancies and not others.

Their report is in the journal Science Advances.
