Welcome to crisscrossing Science, the podcast in which we answer the science questions that you never thought to ask. Every other week, co-hosts Michael Crosser and Chad Tillberg will share their love of natural science by discussing a topic that they find interesting.
||CleanEpisode LVII: Building Eyes from the Ground Up||In this episode, Chad and Mike discuss how complicated organs such as eyes were able to evolve from simple, light sensitive cells, to the vast number of different types of eyes that are found in the animal kingdom.||10/15/2018||Free||View in iTunes|
||CleanEpisode LVI: Consider the Adipose-ibilities||In this episode, Chad and Mike speak with Janet Peterson, a Professor of Kinesiology and Registered Dietitian Nutritionist and Preventive Care Specialist, about fat and fat tissue. Fat cells, also known as adipose cells,||10/1/2018||Free||View in iTunes|
||CleanEpisode LV: Frogpocalypse: The Grim Ribbiter||In this episode, Chad and Mike discuss the rapid decline of amphibian species.

||CleanEpisode LIV: Up in Smoke||In this episode, Chad and Mike invite Bill Fleeger into the studio to discuss policies for forest fires. At one time, the policy of the Forest Service was to extinguish all fires as soon as they start. However,||9/3/2018||Free||View in iTunes|
||CleanEpisode LIII: It's Getting Hot in Here||In this episode, Mike and new co-host Chad Tillberg answer a timely listener question about how to cool off one's house. We then, as is our wont, took a deep dive about thermal dynamics and how air conditioning works.||8/20/2018||Free||View in iTunes|
||CleanEpisode LII: It's Still Good to be the Queen||In this reposted episode, Chad Tillberg joins us in the studio to talk about ants, and bees, and wasps, oh my! Soon, Chad will be joining the crisscrossing team as a new co-host, so listen to the start of it all.||8/6/2018||Free||View in iTunes|
||CleanEpisode LI: Tides: Tidal Forces through the Millenia: A Discussion||In this episode, Mike and Chris discuss the tidal forces and give several examples of where these show up through the solar system. Learn about why Earth has tides, why there is the Dark Side of the Moon, why a moon around Jupiter still erupts,||7/23/2018||Free||View in iTunes|
||CleanEpisode L: Biogeography: Why things are where they are||In the last episode, Chris and Mike briefly touched on how biology and the similarity of organisms can tell us how recently organisms in different areas had been separated. This is a field called Biogeography. And this is the topic for today.||7/9/2018||Free||View in iTunes|
||CleanEpisode XLIX: I Lava you, Man!||In this episode, Mike and Chris tackle a listener request to discuss volcanoes. Why do they occur? Why are some eruptions different from others? Will they ever stop? If you have a question that you would like crisscrossing Science to tackle,||6/25/2018||Free||View in iTunes|
||CleanEpisode XLVIII: Nature AND Nurture||In this episode of crisscrossing Science, Chris and Mike discuss how both genetics and environment affect organisms and how scientists go about trying to determine which has a greater impact. Although this discussion is often framed as nature versus .||6/11/2018||Free||View in iTunes|
||CleanEpisode XLVII: LIVE at the UFO Festival 2018||In this special LIVE episode of crisscrossing Science, Mike and Chris bring a little science to the UFO Festival at McMenamin's Hotel Oregon, in McMinnville, OR. This festival occurs each year in honor of a famous photograph from 1950 that purportedl.||5/28/2018||Free||View in iTunes|
||CleanEpisode XLVI: Two Fun Guys talk about Fungi||In this special episode, we talk about mushrooms, and other fungi. Fungi help to decompose dead objects, which ultimately recycles the constituent pieces. More recently, it has been learned that fungi can also have a mutually beneficial symbiotic r.||5/14/2018||Free||View in iTunes|
||CleanEpisode XLV: Rebroadcast of How Muscles Work||In this rebroadcast, Chris and Mike invite David Altman from Willamette University to talk about his research into Myosin, a protein that the body uses for muscle movement and for transporting materials within cells.||4/30/2018||Free||View in iTunes|
||CleanEpisode XLIV: New Buds of Spring (a very northern hemisphere episode)||In this episode, Chris and Mike discuss how plants prepare for winter and what happens once spring begins again.

||CleanEpisode XLIII: What would you do with three exes?||In this episode, Chris and Mike discuss what happens when the wrong number of chromosomes are passed onto offspring. Nominally in humans, eggs and sperm will carry exactly 23 chromosomes each, which will then combine to form offspring with 46 chromos.||4/2/2018||Free||View in iTunes|
||CleanEpisode XLII: Super cold computers for a super cool future||In this episode we sit down with Norman Birge, a professor of Physics from Michigan State University. He tells us about his research into building computers with superconducting components. He has demonstrated, in principle,||3/19/2018||Free||View in iTunes|
||CleanEpisode XLI: Did you know your cells carry symbiotes?||In this episode, Chris and Mike discuss endosymbiosis, the process in which one organism subsumes another organism to the benefit of both. There is ample evidence that the mitochondria within our cells were once independent bacteria. However,||3/5/2018||Free||View in iTunes|
||CleanEpisode XL: Freakin Magnets, how do those work?||In this episode, Chris and Mike discuss the properties of magnets and magnetism. When most people think of magnets, they think only of the tools used to hold artwork on their refrigerators. But those so-called ferromagnets are only a small subset o.||2/19/2018||Free||View in iTunes|

||CleanEpisode XXXVIII: Flowering Inferno||In this episode, Chris and Mike talk about some of the evolutionary steps that were needed to make so-called angiosperm plants, which are now by far the most common plant type in the world. Angiosperms are plants that have flowers and produce some so.||1/22/2018||Free||View in iTunes|
Awesome work! Looking forward to hear the future episodes.
Making Challenging Topics Understandable
I'm really enjoying this! It's covering a lot of territory in science that I stopped paying much attention to oh, back in high school, but I feel like I'm hanging on. It's digging deeper in its topics than you might hear or see in programs geared to really broad audiences. It's early days with this podcast but I think it has great potential.
Science topics made fun
I love to learn new things, and Michael and Chris have made some complicated scientific topics fun to learn about. Their banter is fun and the topics are interesting!
