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

Typically, animal skin appendages including hair, feathers, and scales are controlled by specific genes when an embryo is developing. There are some exceptions to this rule–including in crocodile ...

The complex 3D shapes of brains, lungs, eyes, hands, and other vital bodily structures emerge from the way in which flat 2D sheets of cells fold during embryonic development. Now, researchers at ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Re-engineering force-regulating proteins inside cells to control their behavior with specific wavelengths of light. Side view of a small group of optogenetically activated cells forming a furrow ...

As you age, your fertility slowly declines. By freezing eggs or embryos when you’re young (usually under the age of 40), you can preserve your eggs’ health and, through in vitro fertilization (IVF), ...

The embryos were created in 1994, while the expectant father was still a toddler, and donated via a Christian “embryo adoption” agency. A baby boy born over the weekend holds the new record for the ...
