It’s not often that mice sneak into the news, but they’ve gotten into it a lot lately.
The story that’s gotten the most attention is about how researchers created “super mice” by injecting nanoparticles into their eyes to give them “night vision.” Here’s a video and links to the stories about that research.

In case you’re wondering what that would look like, here’s a 360° video about how animals see the world that will give you a sense of it. The video concludes with segments on how rats see the world normally (2:32) and snakes see the world in the infrared (3:30).
So that’s “interesting.”
Another story was a bit more entertaining. It involved a critter called Alston’s singing mouse. Here’s a quick one minute introduction and some articles about the talented little guys.

In fact, these mice, and others, actually sing ultrasonic love songs.

Awww, such sweet little fellas! 🙂
Finally, the most interesting news was about how studying the singing mouse’s serenades could lead to treatments for humans with communication disorders that are a result of things like stroke or autism. Here’s a video and some articles about that research.
Singing mice could offer clues about how human brains manage conversation (Jennifer Ouellette, Ars Technica)
These mice sing their little hearts out—and that’s good for neuroscience (Jessica Boddy, Popular Science)

So that’s neat stuff, but if you’re sad because you thought this was going to be about a mouse actually singing a song, with words, here’s a clip from Sing to help you feel better.
