Scientists at Queen Mary University of London and the University of Hong Kong have created a mouse with substituted genes from a single-celled organism known as a choanoflagellate. Scientists replaced ...

In a lab at Queen Mary University of London, a mouse was born whose existence defied conventional biology. It carried within its cells the ancient genetic legacy of a single-celled creature, one whose ...

In a pioneering study, scientists have successfully created a living mouse from stem cells derived from genes that are older than the animals themselves. This discovery has the potential to ...

Scientists have engineered a hybrid mouse with a gene that predates all animal life. The team replaced a single gene in the mouse stem cells with a version from an ancient, single-celled ancestor, and ...
