Humans do not have tails, but do we have “what it takes” for a tail? Hens don’t have teeth, but they have the genes for it. With atavism, it is as if our genomes serve as archives of our evolutionary ...

Scientists captured first real-time 3D video of human embryo implantation, revealing mechanical forces behind successful ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

Over the past year or two, we have been exploring what we termed the origins—or the embryology—of human development. We examined the three pillars of development: Feelings (Affects), Language, and ...

Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the ...

"Volume I ,with 423 illustrations." "Volume II, with 658 illustrations." Volume 1: xviii, 548 pages; volume 2: viii, 1032 pages, 1 leaf of folded plates. Beckwith, J ...

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Endometrial model will revolutionise what we know about embryo development during implantation, supporting our understanding of the causes of early pregnancy loss and serious pregnancy complications.

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

Scientists have developed an experimental way to study how human embryos implant in a uterus, which may provide new insights into why miscarriages occur and how they can be prevented.
