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 ...

STANFORD, Calif. (KGO) -- In the Camarillo bioengineering lab at Stanford, engineers measure impacts both big and small. And that ability can help in research as far ranging as preventing concussions ...

There is variability in when and how cells divide during the development of embryos. While researchers traditionally believed this variability was an obstacle that needed to be regulated, the Hiiragi ...

For decades, scientists knew that male embryos in many mammal species—such as cows, mice, and even humans—tend to grow faster than female ones. But no one really knew why. The new study, published in ...

The technique referred to is non-invasive preimplantation genetic testing (niPGT), also called non-invasive chromosomal ...
