In a scientific “first,” a tiny heart structure composed of human cells has been successfully grown within a pig embryo. Interestingly, this heart kept beating on its own for an impressive 21 days.

Chinese scientists have, for the first time, cultivated a beating heart structure with human cells in a pig embryo, reporting ...

If scientists created a successful human-animal hybrid, would it be entitled to human rights? Does "playing God" with chimera experiments carry unforeseen consequences?

The animal survived for only 10 days, and it is not the first live birth of a chimeric primate. But it is the first such chimera with contributions from an embryonic stem cell, and that stem cell ...

The first-ever live birth of a chimeric monkey grown largely from embryonic stem cells is a feat for stem cell research but raises ethical questions.
