Episode 8: Making Sense of Smell

Armin Kübelbeck, CC-BY-SA, Wikimedia CommonsSmell 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!

Episode 7: Tiny Things Made of Light

Ever wondered what your co-hosts do when they’re not being fab broadcast personalities? Or what the show would sound like if at least one of us really knew what we were talking about? Well listen up, because it’s about to happen: In this episode, Orad describes just what it is he does as a scientist, while Jesse tries to not get confused. Plus, the strangest voicemail we’ve gotten so far… Okay, the only voicemail we’ve gotten so
far…

 

Episode 6: Material Toughness

Professor Steve Yalisove

Do you know what the difference is between a material’s strength and its toughness? If you’re like most of us, you don’t. But that difference plays a big part in why springs don’t snap under pressure and why only certain materials can be used for the frames in buildings and bridges.

Listen in and get the scoop on material toughness and strength as we host our first interviewee, Professor Steve Yalisove of the University of Michigan’s Material Science and Engineering department, where he teaches an introductory material science course. Continue reading

Episode 5: The light show

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!

Episode 4: Speciation: Mini Elephants, Giant Rats and the Cycle of Cichlids

Deep in Africa’s Rift Valley lakes, a story of extinction and evolution is unfolding at an incredible rate, while elsewhere, islands have their own stories of divergent evolution writ large in their fossils. Speciation is an unending process that has shaped our planet’s history in many ways, and continues to do so today.

In this episode, Jesse and Orad tackle the topic of speciation — from its different types to its more extreme cases — along with special guest (and regular behind-the-scenes team member) Aimee Gillespie!

Next episode

Our next show will be about the history of lighting and how the simple light bulb has changed over the years. Post questions below or contact us here!

Note: due to scheduling conflicts with our guest, we will not be able to discuss the planned topic (material toughness) quite yet, but stay tuned! Continue reading

Episode 3: Paul Dirac and the Magnetic Monopole

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!

Next up: Magnetic monopoles

Thanks for the great feedback about episode 2! We’re hard at work taking down notes to make the show better, and make it what you want to hear.

We’re getting together to record the third episode about magnetic monopoles soon. You  still have time to be featured on the mailbag segment of the show if you call in or write in now! You can even reply to this post below, of course. So if you have any thoughts about magnetic charges (or if you still want to talk about black holes), now’s your chance to let us know about them.
