In the first days after an egg is fertilized, throwing a few key genetic switches revs up human embryo development, two new studies suggest. That ignition pattern differs from the one that fires up ...

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 ...

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 ...

Pioneering work has helped reveal for the first time a vital process in the development of the early mammalian embryo. Pioneering work by a leading University of Nottingham scientist has helped reveal ...

NEW YORK – New lab techniques have provided the first good look at a crucial but mysterious stage in the development of human embryos, scientists reported Wednesday. The researchers said follow-up ...

FOR a quarter of a century Prof. Frazer has devoted himself to an intensive study of human embryos and from time to time has published brief accounts of special investigations, more especially on ...

We know much about how embryos develop, but one key stage -- implantation -- has remained a mystery. Now, scientists have discovered a way to study and film this 'black box' of development. This new ...

One of the biggest mysteries of human life is how we develop from a tiny ball of cells into a being with bones, muscle and organs. The process starts inside the mother’s womb shortly after conception, ...
