- Scientists at the University of Cambridge may have just found a way to create life — without sperm or an egg.
- The researchers, who published their findings in the journal Science,

- While scientists have previously created embryos without sperm — as with the Dolly the Sheep clone — creating life without an egg has previously been impossible, Gizmodo reported.
- The mouse embryo was created using embryonic stem cells
and trophoblast stem cells, which are the cells that produce placenta.
- Both were grown separately before being combined using a
three-dimensional scaffold, and the mixture began to resemble a mouse
embryo after four days. Read more (3/8/17 2:45 PM)
