Eating large amounts of ultra-processed food (UPF) is linked not only to reduced fertility in men, but also to slower growth ...

Having a baby in space may require a bit more direction, with new Adelaide University research revealing the navigational ...

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 recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...

A new study suggests humans face barriers to reproducing in space, with microgravity disrupting sperm movement.

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

A new experiment showed that humans may be able to reproduce in space, paving the way for self-sustaining colonies.

Sperm may lose their ability to navigate in microgravity, raising new questions about whether human reproduction is possible in space.

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

Eating large amounts of ultra-processed food is linked not only to reduced fertility in men, but also to slower growth of ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...
