Getting it over the finish line was a labor of love—and now, more than five years after her death, the lab of former Sloan ...

Human embryo models can help researchers study early human development and infertility without relying solely on human ...

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, ...

Biologists have provided new insights on a longstanding puzzle in biology: How complex organisms arise from a single fertilized cell. Producing a new 'gene atlas' with 4-D imaging, the researchers ...

When the egg and sperm fuse, a comprehensive reorganization of DNA begins within the nucleus. Epigenetics plays a crucial role in this process, regulating gene activity through chemical modifications ...

Studying the early development of human embryos is challenging due to ethical constraints and technical difficulties. Therefore, animal models are often used to understand the biological processes ...

Over half of our genomes consists of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the "dark side" of the ...

Biologists have long puzzled over how organs develop into their final shapes, and the nearly transparent bodies of young sea ...
