Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four ...

Human cells have two copies of each chromosome, and this balance is essential for genes to be expressed in the appropriate ...

Researchers at the Max Delbrück Center and the University of Oxford have found that a cellular housekeeping function called autophagy—by which cell components are broken down and recycled—plays a ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Explore the implications of the IVNS1ABP gene in a new genetic disease linked to premature aging and neurological decline.

Plant scientists have identified a protein that plays a previously unknown role in controlling cell differentiation and determining gender in vascular plants, using a fern model. The discovery ...
