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

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

Sperm may carry molecular messages shaped by a father's life experiences, potentially influencing embryo development beyond ...

Researchers from the University of Adelaide have discovered that the earliest days of embryo development have a measurable impact on a person's future health and aging. Professor Rebecca Robker, ...

New York researchers took healthy human embryos and successfully modified their genetic code by focusing on a single letter.

Under his microscope, Jun Wu could see several tiny spheres, each less than 1 millimetre wide. They looked just like human embryos: a dark cluster of cells surrounded by a cavity, and then another ...

Alabama’s Supreme Court has ruled that frozen embryos are people, the first time a court has ever given rights and protections so early after conception. The ruling is limited to Alabama, but it has ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...
