Motherhood takes many shapes.

Mammals change the game by giving birth to live young and feeding them fatty, sugary milk as they get on their feet.

Currently, facilities referred to as “frozen zoos” are used to store samples of animal sperm, eggs and other tissues at cryogenic temperatures

According to a new study by a researcher at the Milner Centre for Evolution at the University of Bath contends that 'selfish chromosomes' are to blame for the early demise of the majority of human embryos. The discovery explains why human embryos frequently don't survive while fish embryos do not have repercussions for the management of infertility.

Scientists working to bring back the functionally extinct northern white rhino announced they had successfully created three additional embryos of the subspecies, bringing the total to 12.
