I require you to look at what these mice do when they are sent in a cage to outer space, thanks to NASA and a brand new study. This new study aims to better understand the adaptations of microgravity in dying mice. If you've read the book Ender's Game, you probably already know what you're going to see.
Usually you only have the floor on which you can play – it's just a surface. Now imagine that you are a small friendly animal and suddenly your limited space expands like never before. You can play on ALL surfaces.
And perhaps more importantly (for the pleasure of the eyes), you can run on all surfaces. Watch as the entirety of the living space becomes the mouse wheel. Watch microgravity become the BEST FRIEND of a mouse.
Researchers at the NASA Ames Research Center responsible for the study showed that the youngest mice in the group appeared to be more active in microgravity than they were on Earth. The same group appears in the video above, presenting a behavior that researchers describe as a "race tracker".
It started with a mouse or two and eventually became a group event. It's like the lemmings of the video game, but for FUN.
Do you know what it reminds me? The sphere of death, they use circus, with motorcycles, and action defying gravity. Below, you'll see the largest number of motorcycles in a death sphere, as presented by Guinness World Records – so you know what I'm talking about.
Back in space, this behavioral mouse study used a rodent habitat module that looked shockingly similar to a standard desktop PC turned to the side. The study took place over 37 days in microgravity. For a mouse, the time is relatively long.
If we look at the overall life span of a mouse versus a human, two mouse-years represent about 70 human years. These mice have spent a quarter of their lives there, about 14 years (if we convert directly into human years).
The mice were well treated throughout the trip and showed about the same weight before and after the mission. Their coats were also apparently in "excellent condition". You can find out more about studying at NASA right now.
