Scientists have created a genetically modified mouse that can run twice as fast as a regular mouse. It can run five to six kilometres at a speed of 20 metres per minute on a treadmill, for up to six hours, before stopping. That’s pretty darn good. The mouse eats twice as much as a regular mouse but weighs half as much. Other side effects are increased aggression, which seems to make sense as you’d think the mouse would need to have higher levels of testosterone. [via ABC]
