By using embryonic stem cell engineering, the researchers were able to reprogram the imprinted genes, effectively allowing ...

Imprinting genes have long been a stumbling block for unisexual reproduction in mammals, but scientists have now found a way past it.

A bi-paternal mouse has been successfully engineered, marking a breakthrough in stem cell research and reproductive biology.

A team of stem cell scientists have successfully used embryonic stem cell engineering to create a bi-paternal mouse -- a mouse with two male parents -- that lived until adulthood. Their results ...

The pygmy mouse lemur is the smallest primate in the world. Its head and body are less than two and a half inches long, though its tail is a bit more than twice that length. These threatened ...
