Mice with two fathers have, for the first time, gone on to have babies of their own, showing that mice created with two sperm cells can be healthy and fertile – and paving the way to a future in which ...

Understanding human gene function in living organisms has long been hampered by fundamental differences between species.

In a lab in Japan, scientists transformed cells from the tails of male mice into eggs. They fertilized the eggs with ordinary mouse sperm and implanted them in surrogate mouse moms. The experiment was ...

A mouse with no biological mother has survived to adulthood in China – a major scientific achievement that's been years in the making. The feat was pulled off by a team of researchers in China, led by ...

For many species, producing an embryo is a bit of a contest between males and females. Males want as many offspring as possible and want the females to devote as many resources as possible to each of ...

A mouse scurries up to six chestnuts. Three look healthy. Three have exit holes where moth larvae ate the insides before they ...

Reproduction is getting so complicated. In the old days, you had only two biological parents — Mom and Dad. But now, up to two women (three if you count a surrogate carrier) can be the biological ...

As detailed in a study published in the journal Cell Stem Cell, scientists achieved this feat of same-sex murine parentage by using CRISPR techniques to rein in rogue genes that undergo a troublesome ...

Logitech is a lithe innovator. Take, for instance, its Wireless DJ music system, which I recently reviewed. Rather than accept Apple’s control over home audio as a fait accompli, Logitech built a ...

Humanized mouse models are vital for studying human gene function, but fully replacing mouse genes with complete human ...
