Slime molds are fascinating. They can live as single-celled organisms or work together as a colony that differentiates functions and exhibits learning behaviors without having anything like a brain. Training one slime mold and then allowing it to fuse with another transmits the training with the new slime mold.

Efforts to save the endangered Fender’s blue butterfly have resulted in quadrupling the population as well as helping save its host plant, the Kincaid’s lupine, from a similar fate!

Ze Frank has dropped another informative and amusing zoology video-- the subject, tarantulas. 

Bumblebees play! I shouldn’t be too surprised since other insects show the capacity for emotion. Fruit flies apparently get down when being rejected by potential mates and drink four times more alcohol than successful ones.
