Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

Life on Earth may have developed the ability to form embryos even before it grew the very first animals. A single-celled organism that lives burrowed in the muck beneath shallow seas bears a startling ...

A single-celled creature originally found in shallow sea sediments around Hawaii develops into multicellular structures with remarkable similarities to animal embryos. The finding could help ...

The first few days of a human embryo’s development, known as pre-implantation, are important. It’s when the first cells are formed, and these decide if the embryo can survive, how it will implant in ...

Scientists at the University of California, Santa Cruz (UCSC), used CRISPR to engineer cellular models of embryos that mimic what happens in the first few days after reproductive cells meet. These ...

At least 8% of the human genome is genetic material from viruses. It was considered ‘junk DNA’ until recently, but its role in human development is now known to be essential Researchers at the Spanish ...

New biophysics research adds to our knowledge about the origins of left-right asymmetry in the body. Most animals, including humans, have bilateral symmetry, which means our bodies are pretty ...
