Biofuel Cell Works in Cactus
Oh yes, you read that right.
Biofuel cell inserted in a cactus and graph showing the course of electrical current as a function of illumination of the cactus (black: glucose, red: O2).
The picture is not big enough to be able to tell what species that is, but I’m guessing a cereus of some type.
With this advance, you could attach a wire to a cactus and you can power a fan  to cool yourself off in the desert. (Well, that’s my interpretation. Your mileage may vary.)
Science!
