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 ...

What if you could precisely change the genome of a pre-implantation human embryo and then safely use that embryo to try to generate a healthier person? It’s a wild idea, but one that technology over ...

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 ...

Human embryo models can help researchers study early human development and infertility without relying solely on human embryos. As the technology advances, these models are becoming more complex and ...

Researchers at the Institute for Bioengineering of Catalonia (IBEC) in collaboration with the Dexeus University Hospital have captured unparalleled images of a human embryo implanting. This is the ...

Destructive Human Embryonic Stem Cell Research—The term “destructive human embryonic stem cell research” means any research that involves the disaggregation of any human embryo for the purpose of ...

Humans do not have tails, but do we have “what it takes” for a tail? Hens don’t have teeth, but they have the genes for it. With atavism, it is as if our genomes serve as archives of our evolutionary ...
