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 the wild, a mouse or rat leads a precarious life. In the city, they dodge traps, poisons, and broom-wielding humans. In the countryside, they face owls, shotguns, and more poison. As Australia’s ...

An international team of researchers has achieved an unprecedented milestone: the creation of mouse stem cells capable of generating a fully developed mouse using genetic tools from a unicellular ...

In a groundbreaking experiment, researchers have brought a mouse to life with the help of a single-celled organism that existed long before any multicellular animals walked the earth. Genetic research ...

Scientists at the University at Buffalo and the Roswell Park Cancer Institute have bred a new form of human-mouse chimera with the highest incidence of human cells ever recorded. Chimeras are ...

The mouse on the left is a chimeric with dark eyes and patches of black fur, a result of stem cells derived from a choanoflagellate Sox gene. The wildtype mouse on the right has red eyes and all white ...
