The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...
A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...
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 ...
Implantation, one of the most poorly understood phases of early human development, occurs in the depths of the womb, at a time when embryos are microscopic, fragile, and well out of reach. Until ...
A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...
Scientists have gotten an unprecedented look at how the human embryo implants in a uterus. They did this by creating very primitive, womb-like environments in the lab. "This is really important work ...
For the first time, scientists have recorded a human embryo implanting into a womb in real time, a feat the researchers hope will lead to new ways to treat infertility and prevent miscarriages. "Being ...
