Dogs Demonstrate Episodic-Like Memory
In humans, episodic memory refers to the recall of a specific autobiographical event – a memory of what happened, where it happened, and when it happened. It was initially assumed that episodic memory is unique to humans, but more recent evidence has brought that assumption into question.
Although we can’t know whether an animal travels back in time in their mind to subjectively remember specific events, like humans do, experiments have revealed memories for what-where-when in animals such as birds, rats, and nonhuman primates -- and now a new study suggests dogs should also join the club.

Vampire Bat Friendships
Mutual grooming and blood regurgitation form the basis of vampire bat friendships, which can last for years. And new research shows that relationships forged in captivity can persist once bats are back in the wild.

These Fish Navigate with Electricity
In my latest Animal Minds post, I take a look at some research with the African elephant-nose fish - an animal that uses self-generated electricity to navigate.

Ants Discriminate Snake Friends and Foes
In Madagascar, there is an ant with two very different relationships to two kinds of snake. These ants open their nests up to one of the snakes, which may help protect them from the other.

Playing with Rats for Science
In a new study illuminating playful behavior in animals, scientists taught rats to play a simplified, rat-versus-human version of hide-and-seek.
Rats picked up the game within a week or two and learned how to alternate between hiding and seeking roles. Rather than offering food, the researchers rewarded successful hiding and seeking behaviors with playful social interactions, such as tickling and petting.
