Ep. 28 Vaccines! Part 1
Monday Feb 17, 2020
Monday Feb 17, 2020
If you're a listener to this podcast, it is probably safe to assume that you have heard of vaccines and likely are pro-vaccine. But there is a lot of cool science going on under the hood of vaccines! This week on Petri Dish Sean, Nathan, and guest Andrei dig in to the stuff that make up vaccines, the different kinds of vaccines, and whether vaccines are dangerous or not (they aren't, really). This is part 1! In part 2 we talk about how they work on a cell biology level and what next-gen vaccines might look like.

Ep. 27 Intermittent Fasting: How, What, and Why?
Monday Feb 10, 2020
Monday Feb 10, 2020
Heya folks, today's episode is about intermittent fasting, a new(ish) and increasingly popular way of trying to lose weight. Is it just a fad diet, or something more complicated? How does someone go about doing intermittent fasting and what does it do on a biological level (as far as we know)?
As a note: Intermittent fasting involves changing how and when you eat, and therefore is a topic that can be sensitive for those who have eating disorders. If you are concerned about the topic, please feel free to skip the episode and/or contact help, like the free helpline of the National Eating Disorders Association: https://www.nationaleatingdisorders.org/help-support/contact-helpline.
Also! Because this topic involves a diet that can impact your health, we want to again mention that this does not constitute medical advice and you should discuss the topic with your doctor first.
This week's promo is for the Not Suitable for Adults podcast! Check them out on twitter: @Not4AdultsCast http://not4adultscast.podbean.com/

Ep. 24.5 Bonus Minisode: Coronavirus!
Sunday Jan 26, 2020
Sunday Jan 26, 2020
Hi Everyone, Happy Year of the Rat! This is a special mini-episode we are releasing on the novel coronavirus currently infecting people in China (and now elsewhere). This short episode covers what a coronavirus is in general, and what we know about this new one. It also has a little conspiracy theory stuff at the end, but that's just for light hearted purposes, because all in all new diseases can be dour business. Listen in to learn some stuff, and realistically, don't panic!

Ep. 24 Aging and Immortality Part 1
Monday Jan 20, 2020
Monday Jan 20, 2020
For folks in the USA, happy Martin Luther King Jr. Day! This week on Petri Dish Nathan and Sean discuss the biology of aging. What does it actually mean to age, when some animals out there are biologically immortal and get to just hang out forever until they get eaten? What happens on a cellular level when we age? What can we learn from other species about the aging process? This is the first part of a two-part series -- next week we'll discuss human aging in the context of what we can try to do to slow or halt it!

Ep. 23 Booze and Hangover Science
Monday Jan 13, 2020
Monday Jan 13, 2020
Welcome to the first Petri Dish episode recorded in 2020! This one is about the science behind the effects of booze (ethanol), and our current best understanding of what hangovers are and what you can do about them! Would this episode have been more apropos if released closer to New Year's Day? Maybe, but we were all too hung over, so whatever. Tune in for a brief history of alcohol, a discussion of what ethanol does to you, and whether that stuff about a glass of wine a day being good for you is real or not. Do hangover cure IV bangs work? Did you even know that was a thing? What about prairie oysters? Doesn't that sound more like a euphemism for poop than a hangover cure? Tune in!

Ep. 22 What is Epigenetics?
Monday Jan 06, 2020
Monday Jan 06, 2020
In this week's episode, Sean and Nathan are joined by guest Liliana Escobedo to discuss epigenetics, which is either all of the stuff besides your genes that affects the functions of your cells OR non-genetic stuff that happens in your life that can affect your kids and grandkids, depending on what scientists you ask for a definition! Can eating too much food during your lifetime affect your grandkids through your sperm or eggs getting tweaked? Find out this week on Petri Dish!

Ep. 21 Human Sex and Evo Psych
Monday Dec 30, 2019
Monday Dec 30, 2019
Hey everyone, this week is part 2 of our episodes on sex, this time focusing on sex determination in humans and Sean's rocky relationship with the field of evolutionary psychology! Nathan and Sean discuss the XY chromosome system, the SRY gene, all sorts of things that can make people fall outside of the XX-XY female-male dichotomy, and more!
This episode our very real promo is for a non-fiction horror podcast Pomegranates and Pitchforks! They cover true crime, mythology -- anything that has to do with horror -- check them out! https://pompitchpod.podbean.com/

Ep. 20 Animal Sex! Part 1
Monday Dec 23, 2019
Monday Dec 23, 2019
This week on Petri Dish Sean and Nathan dive into the apparently controversial topic of biological sex. In this part 1 of a two part discussion, Sean and Nathan talk about the biological basis for the concepts of 'male' and 'female' in non-human organisms ranging from yeast to plants to reptiles. They bring up different kinds of chromosomal systems, weirdos like the platypus and clownfish, and whether climate change could turn more sea turtles into ladies!
In this episode we feature a promo for another podcast, Just the Zoo of Us. If you like animal facts, check them out! https://www.justthezooofus.com/
