Embryo-like structures were sent onboard the Chinese space station and will spend five days in low-earth orbit. There are a number of things we take for granted here on Planet Earth that are ...

Our ancient past isn't always buried history. When it comes to our DNA, nearly 9% of the human genome is made up of leftover genetic material from ancient viruses (called endogenous retroviruses or ...

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 - ...

China has become the first nation to send human artificial embryos into orbit, aiming to uncover how space conditions like ...

It's a question that has baffled scientists for decades: could humans ever have babies in space? Now, China has taken a major ...

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 ...

A stem-cell-based monkey embryo model that self-organizes into a comprehensive body plan could lead the way to more-sophisticated models of early human development. Xiangyu Kong is in the Department ...

Summary: A father’s psychological stress prior to conception can actively alter his offspring’s physical growth via small molecular signals carried in sperm. The research demonstrates that prolonged ...

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 ...

Researchers reveal that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development. CRCHUM researcher Sophie ...
