Stem-cell models provide evidence that viral DNA sequences that entered the human genome in the past were repurposed to aid early stages of embryonic development. Sherif Khodeer is in the Department ...

The first steps of human development—those that occur within the first few weeks of pregnancy—remain mysterious in many ways. Within a week of fertilization, human embryos form a blastocyst, which ...

Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

We have long believed that brain growth stops and aging begins once we pass the age of 20. However, a study by British ...

Step one: very small, immature human eggs within ovarian tissue are placed in culture in the lab, and begin to develop Step two: after initial development, eggs have grown and are more than double ...

The future of science is increasingly prominent, and is now reaching the early stages of the formation of life. A new study published in the scientific journal Nature, reports scientists have created ...
