Imagine you are at a party, talking to someone you’ve never met. Underneath the smiles and polite small talk, you are subconsciously sizing-up whether this person is friend material.

Most animals rely on their sense of smell when interacting with others. And researchers in Israel speculated that it plays a role in human friendships, too.
