An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic ...

The embryos cannot develop into humans, and are being used to study development in outer space.

Two new breakthroughs show how hard it is to know when the world has changed.

A University of California, Riverside study reports that cells in the earliest stages of human development could be susceptible to infection by SARS-CoV-2, which causes COVID-19, offering new insight ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

The discovery of a gene essential to early embryonic development sheds light on the preliminary stages of human placenta formation. A team led by scientists from the University of California San Diego ...

Chinese researchers sent artificial human embryo models into space to study how microgravity may affect early human ...

Microscopy image of a PGA at day 8 showing the early tissues supporting the embryo, including the amniotic sac and the yolk sac-like structures, surrounded by (extra-embryonic) mesoderm tissue.

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 ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production ...
