Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Selecting the healthiest embryo is one of the most important steps in in ‑ vitro fertilization (IVF), yet it remains one of ...

STANFORD, Calif. (KGO) -- In the Camarillo bioengineering lab at Stanford, engineers measure impacts both big and small. And that ability can help in research as far ranging as preventing concussions ...

Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into collagen designed to mimic uterine tissue —a key stage in reproduction. The ...

A newly created cell model of the amniotic sac could reveal new insights into early pregnancy, as well as generate helpful products for medical use. When you purchase through links on our site, we may ...

For decades, scientists knew that male embryos in many mammal species—such as cows, mice, and even humans—tend to grow faster than female ones. But no one really knew why. The new study, published in ...
