Scientists in Japan have developed a rat-mouse hybrid embryo from a single frozen rat chromosome transplanted into a mouse egg cell. The achievement is proof that genetic material can sometimes remain functional after cryopreservation and be expressed inside the cells of a completely different species. This is giving renewed hope to the idea that we may one day be able to partially resurrect extinct species and study lost traits.
