The success of in vitro fertilization depends on many factors, one of which is sperm viability. A recent study from the ...

Several states — like Arkansas and Michigan — have implemented explicit bans on all forms of human cloning.

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists at UC Santa Cruz were able to create “programmable” cellular models of embryos without ...

Scientists have found a way to study early embryonic development without real embryos. Using CRISPR, they programmed stem cells to self-organize into structures mimicking early embryos. The cells show ...
