6 core challenges that researchers must consider as the race to create models that are ever closer to real human embryos ...

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 ...

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 ...

(NewsNation) — For the first time, scientists have successfully created human eggs from skin cells that can be fertilized. This groundbreaking study could transform fertility treatment and expand ...

Growing tissues can crack, break, and dissociate to form structures that can later withstand immense forces.

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 ...
