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

An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic models based on stem cells in the field of reproductive biology. The document, ...

The Chinese Academy of Sciences has announced an amazing and potentially controversial new project to test the development of ...

Successful fertility treatments, including in vitro fertilization (IVF), is often reliant on a clear understanding of developmental stages of human development. Clinicians working with assisted ...

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 - ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

The work proves that embryo editing is far from a clinical reality. But the experiment has sparked controversy nonetheless ...

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 ...

Could your diet before conception shape fertility and early development? New research reveals sex-specific links between ultraprocessed foods, reduced fertility in men, and subtle changes in early ...

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 ...
