Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

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

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

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 ...

Having a baby in space may be far more complicated than expected, as new research shows sperm struggle to find their way in microgravity.

Why do pregnancies last longer in some species than others? Researchers have found the clock that sets the speed of embryonic development and discovered the mechanism is based on how proteins are made ...

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 study reveals that consuming ultra-processed foods may affect men's fertility and early embryo development. While men risk ...

“A central question has been: How do thousands of genes work together in an embryo, and how is their activity linked to the movement of cells?” says first author Yinan Wan. To answer this question, ...

Eggs take exactly 21 days to hatch, and the process of chick development is an exciting opportunity for your students! We are working to create lessons, videos and resources for you to use in your ...
