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 ...

It’s still one of the biggest mysteries in science: How does a human cell — too small to see with the naked eye — divide and reproduce to ultimately become a human body made up of more than 30 ...

The biological and legal definitions of “embryo” don’t match, and that will become a problem, according to Nicolas Rivron, PhD, of the Institute of Molecular Biotechnology of the Austrian Academy of ...

Scientists can now create embryo-like structures from animal and human stem cells in the lab, and recently, researchers unveiled the most advanced human embryo models yet, which resemble natural ...
