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

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

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 ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

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

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.

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 ...

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 ...

A new study from the MRC Laboratory of Medical Sciences (LMS) in London, UK reveals how ancient viral DNA once written off as ...

"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 ...

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 ...
