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 ...

Frozen embryos are filling storage banks around the world. It's a struggle to know what to do with them. Lisa Holligan already had two children when she decided to try for another baby. Her first two ...
