The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

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 ...

Ancient viruses are embedded everywhere in the human genome. Estimates range, but it's thought that about eight percent of the human genome could be made up of these ancient retroviruses, which are ...

Breakthrough raises new possibilities for regenerative medicine, which uses patient’s own cells to repair damaged tissues Scientists have grown embryo-like structures in the laboratory that produced ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production ...

Scientists have gotten an unprecedented look at how the human embryo implants in a uterus. They did this by creating very primitive, womb-like environments in the lab. "This is really important work ...

Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into synthetic uterine tissue—revealing a key stage in reproduction. The resulting ...

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 ...

Scientists have for the first time ever filmed a crucial step that leads to new human life – cracking open a 'black box' of early development, and potentially helping with fertility treatments. Every ...

Scientists have for the first time grown human embryos outside of the mother for almost two full weeks into development, giving unique insight into what they say is the most mysterious stage of early ...
