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 ...

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 ...

Advances in organoids and embryonic models of human development have the potential to prompt social and existential questions --e.g., what defines human individuality? However, bioethicists say that ...

Thanks to continuous advances in human stem cell research, studies that make use of embryo models are progressing quickly. This research offers both a scientific and ethical alternative to the use of ...

It is time for a redefinition of the human embryo, a team of researchers has proposed. Advances in recent years have shown that human stem cells can be used to make embryo-like structures, called ...

Biotech discoveries are coming at us so rapidly they've apparently outpaced the government's ability to evaluate or even define them. Here's an example: Researchers at several prominent U.S.
