These critters are probably just the ticket if you're planning to hold the first annual Mous-O-lympics, but how do they fare in the wild?

Unless their chance of death by hazard is substantially reduced, there's not much use for their longevity. How well do their muscles develop on a meager diet of human food scraps? How's their immune system? Since they're not genetically diverse, better hope they're not carrying any genetic defects. And so on.

I'll believe that these are the bane of exterminators when they've been pitted against the mice that have co-evolved with humans. Until then, my working assumption is that the ones that do survive a few generations will begin to seem more and more like their peers.

this will end well.

I think "20 meters per hour" should be "per minute." That's what the video seems to show.

oh come on, rejoice! the more important question is who would win: mighty mouse or superman?

Mr. Trouble never hangs around

When he hears this mighty sound...

"Here I come to save the day!"

That means that Mighty Mouse is on the way.

Yessir when there is a wrong to right

Mighty Mouse will join the fight

On the sea or on the land

He gets the situation well in hand

So though we are in danger

We never despair

Cause we know that where there's danger

He is there!

He is there!

On the land!

On the sea!

In the air!

We're not worryin' at all

We're just listenin' for his call

"Here I come to save the day!"

That means that Mighty Mouse is on the way!

KHAAAAAAAAAAAAAAAAN!!!

Seriously, ever worked in a lab with mice? The mice end up everywhere.

Like they needed the help! The rats and the cockroaches are going to survive longer than us anyway.

Congratulations, you've just seen the future.

Wait till they get loose. What harm could a mouse do, right.

Say hi to our new overlords.

My guess is that because these mice have a higher metabolism, they will require that much more food to stay alive. Therefore, in situations with abundant food, super-mice are more competitive. But, in situations where food is scarce, I would bet that normal mice would out-perform the super-mice.

...how do they manage to make a mouse run for 4 hours straight?? I know that for me to do that would take some serious incentive (like being paid as a volunteer test subject), but last time I checked, mice don't take cash.

I think the wild mouse is smarter and gets off the treadmill because clearly - he isn't going anywhere.

As long as these little bastards will still stick to a glue trap, I'm good.

I'll bet the super-mice use mousetrap levers for a little bench-press.
