A “mighty mouse” with double the normal muscle strength has been created by scientists looking for ways to treat age-related diseases. It not only has bigger muscles but, in tests, could run for twice as long on the treadmill¹.

Swiss scientists created the super strong “marathon mice” by changing a gene slightly and found the mice’s muscles became bigger and they had more energy.

The “marathon mice” were able to run faster, longer and cover twice as much distance as common mice and were also better at putting up with cold conditions.

If the effects could be replicated² in humans, scientists believe it could lead to treatment against muscle-wasting in the elderly which can lead to falls and broken bones.

Similar results were found when the same experiment was repeated on worms. The scientists believe the modification³ could potentially be applied to humans.
