"These cells co-develop together, just like they would in an actual embryo, and establish that history of being neighbors," ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

Human biology is not black and white. Although newborns are typically categorized as male or female at birth based on visible ...

Scientists have found a way to study early embryonic development without real embryos. Using CRISPR, they programmed stem cells to self-organize into structures mimicking early embryos. The cells show ...

The ovary is the female gonad, which houses egg cells. Women are born with all the eggs they will ever have, and each egg is ...

The learning ability of children with Down Syndrome may vary from child to child and it may typically range from mild to ...

Just because a sperm is a strong swimmer doesn't necessarily mean it has the right amount of DNA, Dr. Lisa Lee told Newsweek.

It's commonly thought that sperm "race" to the egg, with the winner fertilizing it. But is this really the case?
