Some parts of the human body are in a state of constant regeneration. Liver cells, for example, are replaced every 300 to 500 days. Fingernails grow every day. But this aptitude rapidly declines when ...

Depending on your point of view, the creation of an embryo that is part-human and part-monkey is either a great opportunity for medical experts to create organs and tissues for human transplantation; ...

The Endless Frontiers Act, a comprehensive bill sponsored by Sen. Chuck Schumer, D-N.Y., passed the Senate on Friday, leading some critics to point to a little-noticed move that could open a ...

There are hundreds of different cell types that make up the human body, each derived from a single origin: the fertilized egg. Researchers investigating how this complexity arises have made ...

April 22 (UPI) --Scientists have created the world's first monkey embryos containing human cells in an attempt to investigate how the two types of cell develop alongside each other. The embryos, which ...

An intense debate has flared over whether the federal government should fund research that creates partly human creatures using human stem cells. The National Institutes of Health declared a ...
