Scientists captured first real-time 3D video of human embryo implantation, revealing mechanical forces behind successful ...

At first glance, it looks like the start of a human pregnancy: A ball-shaped embryo presses gently into the receptive lining ...

The most advanced lab-made human embryo models look like the real thing — they resemble, though don't perfectly replicate, natural embryos about 14 days into development. These lab-made embryo models ...

The traditional way to make an embryo is to combine a sperm cell with an egg, often after dinner and a bottle of wine. But a new way may be around the corner. In recent years scientists have ...

STORY: This looks a lot like a human embryo. But it was created without sperm, eggs, or a womb. It was made in a lab, by a group of scientists in Israel. And what they've created so far offers a new ...

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 ...

Embryos and the uterus exchange molecular signals within the first hour, shaping whether implantation succeeds or fails.

Australian scientists have discovered quail eggs can help them understand birth abnormalities and other developmental health concerns. They use these eggs to observe embryos in real-time and in high ...

Researchers have developed a method for culturing fertilized chick eggs without their shells. The eggs were placed in an artificial culture vessel made of transparent film, allowing for real-time ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

Although scientists know a lot about the process of human embryo implantation, it had never been recorded in real time, until now. Now that investigators can observe it in action, they may be able to ...
