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

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

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 ...

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

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

Researchers have developed a new embryo-like model derived from adult cells that replicates key features of early human development, including the generation of blood cells. University of Pittsburgh ...

Around eight days after fertilization, the human embryo implants in the endometrium (the tissue that lines the uterus). After implantation, it enters a developmental phase that is not well understood ...

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 - ...

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 new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment. The study led by at the ...
