On todays Dear Science segment, AUT's very own Allan Blackman joins us to talk about how having a canine companion may make us happier. We get into the nitty gritty of recent studies claiming to have performed head transplants on humans (SPOILER ALERT: They are already dead). And finally we talk about how Chuck Norris is sueing the big pharma companies behind gadolinium, a contrasting agent for MRI scans after he claims it effected his wifes health.
