What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

Scientists captured first real-time 3D video of human embryo implantation, revealing mechanical forces behind successful pregnancy.

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. A new study using stem ...

The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

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 ...

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...

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 ...

The proponents of abortion, embryonic stem cell research and cloning refer to human embryos as just clumps of indistinguishable cells not yet human. If that were the case, those indistinguishable ...

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 ...

Megan Molteni reports on discoveries from the frontiers of genomic medicine, neuroscience, and reproductive tech. She joined STAT in 2021 after covering health and science at WIRED. You can reach ...

The research team discovered that glassware used to manipulate and culture fertilized eggs in the fields of assisted reproductive technology (ART), livestock farming, and basic research contains toxic ...
