I Came For Science

Most of us have received a disappointing gift at some point, maybe an ugly sweater from a relative, or a beautifully wrapped package that turns out to be completely useless.

Humans know this feeling well. But surprisingly, so do spiders.

In this episode, our guest, Dr. Maria Albo, takes us into the world of nuptial gift-giving spiders, where males present females with carefully wrapped packages during courtship and many of those gift...

Imagine a species where females rely on males from another species to reproduce… but never use their genes. That’s not science fiction, that’s real biology, and we are here to tell you the story of the Amazon Molly. In this episode, Laura is joined by Sanaa Khan, a PhD Candidate at University of California, Davis who studies this incredible system. We will be talking about how the species reproduces, what it mean...

Ahhh, frogs calling. A sure sign of spring. But can you tell the difference between the songs of attractive and unattractive frogs? Our guest, Olivia Feagles, can. In this episode, Dr. Feagles explains how to measure the attractiveness of frog calls. In her studies, she found that female frogs vary in what they find attractive in a male song and how far they are willing to travel for their preferred mate.

Finally, she discusses how...

In the spirit of normalizing talking about topics related to sex, we give you "Masturbation: An Evolutionary Perspective". In this episode, Laura interviews evolutionary biologist Matilda Brindle about her research in which she uses evolutionary methods to test hypotheses about when and why masturbation evolved. Matilda shares with us how she came to this area of research, what is known about masturbation in other animal species, w...

Most tweens and teens have been exposed to porn, whether intentionally or unintentionally. What are the impacts of porn use on adolescents? How should parents or guardians respond to adolescent porn use? These are some of the important questions being addressed by our guest in this episode, Dr. Megan Maas. Laura and Megan discuss the challenges of studying adolescent porn use and what has been found in this area so far. More resour...

After Episode 22 where we discussed the diversity and evolution of male genitalia, we had lots of questions. One thing we were left wondering was why we know less about female genitalia and what is the current state of this field. To dig into this topic more, Laura interviewed Dara Orbach who studies the reproductive biology of cetaceans with a focus on understanding the genitalia of both males and females, and how they interact. T...

Did you know that animal penises come in a wide variety and that some animals have bones in their penises? In this episode, Laura talks with biologists Dave Hosken and Matt Dean about the wide variety of penises found in different animal species. We discuss some of our favorite examples and then explore hypotheses for why such variation evolved. Matt shares his lab's research findings on the evolution, function, and development of ...

Did you ever wonder why there are not more male contraceptives? In this episode, team member Daphne Trillana asks the question "where are the promised new male contraceptives"? Laura and Daphne discuss this issue and then Laura talks with two experts in the field: Logan Nickels of The Male Contraceptive Initiative and Dr. Stephanie Page, an endocrinologist who develops and studies new methods of male contraception. Together, they e...

Welcome back to Season 4 of I Came For Science. In this episode, Laura interviews Dr. Meg Martin about her research on conservation breeding. Conservation breeding is a method of increasing the populations of endangered and threatened species by having them breed in captivity and then releasing the resulting offspring into the wild when they are old enough. Traditionally, breeding pairs were chosen to maximize the genetic diversity...

Were you that kid who always kept asking "But, why?" after adults in your life answered questions. Or, do you know a kid like that? Our guest for this episode, Dr. Nathan Burke, was that kid. His parents and teachers would get annoyed by all his questions until he found "his people" among evolutionary biologists. Evolutionary biologists persistently ask "But, why" questions about the way the biological world works. In this episode,...

In this episode, we continue exploring the science of female arousal. Laura interviews Maureen Pollack, a mompreneur. She is the inventor of the WaterSlyde, a water-based device designed for female pleasure. Maureen explains how she developed the idea and the prototype for the WaterSlyde and what she learned about female arousal, the sex toy industry, and, even, plumbing along the way! It is a delightful story of self-discovery tha...

We are now embarking on an exploration of the science of female arousal. In the first episode of this series, Laura interviews her former student and current colleague, Harper Jones. Harper is pursuing a PhD in clinical psychology in the Women's Integrative Sexual Health (WISH) Lab. In this episode, she explains the methods that the WISH lab uses to measure arousal and what research questions can be addressed with these methods. Sh...

Welcome back to Season 3 of I Came For Science. If you are just joining us as a listener, we encourage you to listen back to Seasons 1 and 2 to hear our episodes on a range of topics including pubic hair, polyamory, spider sex, reproductive losses, and queer family building.

Whether you like it or not, your children are going to learn about sex. Wouldn't it be good if they learn accurate information from a trusted adult?

In this ep...

In our final episode of Season 2, we explore the science of sperm storage. Sperm storage occurs when sperm viability is maintained outside of the male reproductive tract. This process happens, at least for some time period, naturally in all internally-conceiving animals. Sperm storage is also used by humans for assisted reproduction and fertility preservation. We learn about both processes through interviews with Dr. Teri Orr who s...

This episode follows up on our last episode about family building. In this episode, Laura talks with Dr. Christa Craven about reproductive losses, especially as they are experienced by people who are LGBTQ+. These losses come in a variety of forms and times during the family building process and can be impacted by environmental and social stresses. Laura and Christa also discuss how the causes of reproductive losses in humans relat...

In this episode, Laura interviews Liam Kali a licensed midwife who is a pioneer in extending the practice of midwifery to queer families. Liam literally wrote the book about queer family building through conception. Liam describes their professional and personal journey becoming a parent, a doula, and a midwife, as well as the successes and challenges they faced along the way. Liam describes methods that queer people use to concei...
