We usually assume that tissue folding (the process that creates organs, embryos, and the deep ridges of the human brain) ...

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 ...

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), ...

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 ...

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 ...
