Dan Riskin, CTV’s Science and Technology Specialist, rounds up the most interesting, strange, and fascinating headlines from the science and tech worlds and teaches you a little something Thursdays on Ottawa at Work with guest host Graham Richardson.

Here's what we're covering this week:

• Maybe the reason “Common Sense Isn’t All That Common” is that we can’t agree on what “common sense” is
• Is there a bad side to coffee?
• Why do dogs wag their tails? 

Tune in every Thursday at 10:35am to Ottawa at Work with Patricia Boal for the latest Science with Dan Riskin!
