A new "atlas" of early embryonic development in mammals suggests that the process is highly chaotic — but there is some method to the madness.

By examining embryos from several mammals, the team discovered that ancient viral sequences hidden in DNA, long thought to be extinct, come back to life during early development.

The first mice to be created from two fathers, a phenomenon known as androgenesis, have now produced healthy offspring for ...

Embryonic sex development is a complex process. You may have heard the idea that, at first, all embryos are female until later in their development. This isn’t exactly true.

How Other Mammals Hit the Pause Button on Their Development In the animal kingdom, some mammals, like kangaroos and bears, can naturally hit the “pause button” on pregnancy.Known as embryonic ...

In some mammals, the timing of the normally continuous embryonic development can be altered to improve the chances of survival for both the embryo and the mother. This mechanism to temporarily ...

Kangaroos aren't endangered, but Australia — one of the world’s most biodiverse countries — also has the highest rate of mammal extinction. A breakthrough may help fix that.

By examining embryos from several mammals, the team discovered that ancient viral sequences hidden in DNA, long thought to be extinct, come back to life during early development.

A new "atlas" of early embryonic development in mammals suggests that the process is highly chaotic — but there is some method to the madness.

But what exactly flips that switch—and how it works across different mammals—has remained a mystery. A new study by r Ancient DNA is still shaping early embryo development in humans and other ...
