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 ...

Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called ...

A new study found that microgravity simulated on Earth hindered sperm cell movement, egg fertilization and embryo development ...

Scientists at the University of California, Santa Cruz (UCSC), used CRISPR to engineer cellular models of embryos that mimic what happens in the first few days after reproductive cells meet. These ...

"Understanding embryo implantation and embryo development just after implantation has significant clinical relevance as these stages are particularly prone to failure," said Dr. Peter Rugg-Gunn, ...

Scientists have gotten an unprecedented look at how the human embryo implants in a uterus. They did this by creating very primitive, womb-like environments in the lab. "This is really important work ...

Ancient viruses are embedded everywhere in the human genome. Estimates range, but it's thought that about eight percent of the human genome could be made up of these ancient retroviruses, which are ...

Scientists interrogate leftover culture media to noninvasively determine the quality of embryos in the lab, providing a way to better predict in-vitro-fertilization (IVF) success. Researchers at the ...

A system which replicates the womb lining (endometrium) with high biological fidelity has been developed by researchers at the Babraham Institute and used to listen in to the communication that ...
