Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called ...

In a scientific breakthrough that raises a number of medical and ethical issues, researchers have used stem cells to create living, growing models of a human embryo. Because stem cells were used, ...

On the outside, you’ll watch your little one grow from newborn to older infant to toddler, preschooler, kindergartener, and so on. It might feel like it goes by in the blink of an eye. But a little ...

Researchers have created model embryos from mouse stem cells that form a brain, a beating heart, and the foundations of all the other organs of the body -- a new avenue for recreating the first stages ...

In science, ethical guidelines ensure that research takes place in a way that respects public trust and is conducted responsibly. Traditional ethics approval procedures work well for projects ...

Scientists have created the miracle of life — no male or female necessary. Using only a mixture of stem cells, University of Cambridge researchers were able to generate a live, “synthetic” mouse ...

Scientists have created mouse embryos in a dish, and it could one day help families hoping to get pregnant, according to a new study. After 10 years of research, scientists created a synthetic mouse ...
