Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into collagen designed to mimic uterine tissue —a key stage in reproduction. The ...

A stretch of viral DNA in the mouse genome gives cells in early-stage embryos the potential to become almost any cell type in ...

Ancient viruses are embedded everywhere in the human genome. Estimates range, but it's thought that about eight percent of the human genome could be made up of these ancient retroviruses, which are ...

Faced with demographic collapse in her home country, the Chinese expert is conducting experiments on stem cells and human ...

Researchers have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is ...

The proponents of abortion, embryonic stem cell research and cloning refer to human embryos as just clumps of indistinguishable cells not yet human. If that were the case, those indistinguishable ...

Researchers reveal that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development. CRCHUM researcher Sophie ...

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 invented a device that can quickly produce large numbers of living entities that resemble very primitive human embryos. Researchers welcomed the development, described Wednesday in the ...

Megan Molteni reports on discoveries from the frontiers of genomic medicine, neuroscience, and reproductive tech. She joined STAT in 2021 after covering health and science at WIRED. You can reach ...

Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into synthetic uterine tissue—revealing a key stage in reproduction. The resulting ...

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 ...
