Our lofty friends, the giraffes, are slowly and quietly disappearing from the wild. Some organizations are trying to help ...

Researchers have gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization, each cell has the ...

"Chimeras are the result of fusion of two zygotes to form a single embryo, producing an individual with genetically different kinds of tissue. If the fused zygotes are of different sex, the individual ...

Nearly half the embryos studied underwent developmental arrest because of genetic mishaps in early development — a revealing insight that suggests more IVF babies could come to term with changes in ...

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

The team placed blastocysts—embryos 5-6 days after fertilization that were donated following IVF procedures—onto the artificial endometrium. The blastocysts attached to the surface of the lining, ...

Only one in three fertilizations leads to a successful pregnancy. Many embryos fail to progress beyond early development. Cell biologists at the Max Planck Institute (MPI) for Biophysical Chemistry in ...

Scientists have created embryo models to help study the mysteries of early human development, the medical problems that happen before birth and why many pregnancies fail. These models are made from ...

When sperm meets egg, the start of life is not quiet. Under a special microscope, researchers have watched a tiny light show at fertilization. They see a microscopic flash at fertilization, a burst of ...

IVF is beaming hope to couples facing issues of infertility. Not only does it handle the inability to conceive, but it also offers a perfect environment in which the implantation and early development ...
