Smell is a powerful thing. In fact, some say it’s the most powerful of our senses. But it’s not a well-understood sense by any means. Every now and again, a new study appears with a new set of categories or a new angle, but for now, the definitive answer on how smell really works remains elusive. A recent study set the number of odour categories at 10, but the YASSers think that something about it just smells off. Take a listen to find out why.
After a brief hiatus, the guys are back! Orad and Jesse introduce their new co-host Nina Pariser and discuss smell. Plus, our first legit voicemail!
Philips LED lightbulbs on sale in a Canadian hardware store.
The lightbulb, right? The good old incandescent lightbulb.
Well, it’s maybe not so good anymore. Or comparatively speaking, at least. New lights that boast better energy use and less waste heat are changing the field for the better — or so some would claim. Others prefer the light and warmth offered by the old-fashioned bulb. No matter which side you’re on, the fact is that there’s more than one way to light a room, and we’re talking all about it in this episode. So settle in, give us a listen… and then maybe get in on the conversation!

Magnetic monopoles are one of those things that really should be real. There’s practically an empty space in physics waiting to be filled by them. But nobody’s found one yet.
In some ways, Paul Dirac was as elusive a figure as his monopoles are. Taciturn, impossible to know and sometimes downright bizarre, he nevertheless gave the world of science some of its most enduring theories and equations.
Join us for a discussion on Paul Dirac and the magnetic monopole, featuring Orad’s new microphone and Jesse’s wicked head cold.
Our next episode will be about genetic diversification, so write in or call about it if you’ve got questions you want us to answer!
