Why do some rove beetles look like ants? Why do living things evolve similar solutions to common problems? Is there predictability within the evolutionary process?
On this episode, Art and Marty talk with Joe Parker, an entomologist at Caltech. Joe has been collecting beetles since the age of 16, when he first became amazed by their incredible diversity. He now focuses on rove beetles and studies their evolutionary relationship with ants to understand how different species converge upon similar traits.
In this episode, we've taken a break from our regular format to answer some of your questions such as what's the chance of human-like intelligence on another planet and if we had the technology, what organism would we want to bring back, Jurassic Park style?
Tune in to this episode to hear Marty and Art answer questions like these and what goes into making our podcast!
How does our indoor, modern lifestyle affect our microbiome? How does this novel microbiome affect our health?
On this episode, Marty and Art talk with Rob Dunn, an applied ecologist at North Carolina State University. Rob studies the organisms that we come into contact with every day, from the microbes in our bodies to the insects in our homes. Tune into this episode to hear Marty and Art talk to Rob about the crazy diversity of microbes on our skin and its importance in our health and our food. Many of the ideas we discuss are from Rob’s most recent book, Never Home Alone.

How can cicadas eat nothing but tree sap for 17 years? How do endosymbiotic relationships evolve? What do bacteria-insect symbioses teach us about the evolution of mitochondria and chloroplasts?
On this episode, Art and Marty talk with John McCutcheon, an evolutionary biologist at the University of Montana. John studies symbioses between bacteria and cicadas—exploring what each partner provides for the other, how cicadas transmit bacteria to their offspring, and what the consequences are for the evolution of bacterial genomes (hint: they are extreme!). This research raises basic questions about what an individual even is.

What role does one part of the federal government, the National Science Foundation, play in biological research in the US? How will their new funding initiative help us discover Rules of Life?
On this episode, Art and Marty talk with two NSF directors, Joanne Tornow . the head of the Biological Sciences directorate, and Arthur “Skip” Lupia , the head of the Social, Behavioral and Economic Science directorate.
They talked with them about one of NSF’s Big Ideas. One Idea, called Rules of Life, challenges scientists to study some of the same ‘big’ questions that we’ve addressed on this podcast, including how genotypes become phenotypes. They also asked how an agency dedicated to advancing science operates within an executive branch that has publicly criticized some major scientific conclusions.
Joanne does not have a Twitter account, but you can follow her directorate here: @NSF_BIO
How is climate change affecting the distribution of animals? How will these changes in species distribution affect us?

Will cancer ever become just another chronic but manageable disease? What can a squirrel biologist teach us about treating cancer?
In this episode, Marty and Art talk with Joel Brown about how to contain cancer using basic ideas from ecology and evolution. To Joel, cells in tumors are like organisms in ecosystems, and fighting cancer means using what we know about species in nature to tilt the playing field against the worst kinds of cancer cells. He and his team at the Moffit Cancer Research Center in Tampa, Florida, are starting to have some remarkable success treating different kinds of cancer.
We interviewed Joel in front of a live audience at Circa 1949 in Tampa, FL—our first live event! We had a great time interacting with the audience and plan to do more events like this in the next few months. If you’d like to host a Big Biology event, please email us at email@example.com!
Why do some animals have weird genitalia? Why is there conflict between males and females when it comes to producing offspring?
Tune into this podcast to hear Art and Marty talk with Patty Brennan about how sex in the animal kingdom is not always about love and cooperation; often it's also about conflict. And, this conflict can lead to some pretty crazy genitalia. Patty is an evolutionary biologist at Mount Holyoke College. Her research shows that the birds and the bees aren't so simple for the birds (or, as it turns out, for most other animals).

What is life? How did life arise from non-life? What did life look like at its origin?
Tune into this podcast to hear Art and Marty talk with Sara Walker, an expert in astrobiology and theoretical physics at Arizona State University. They discuss how life might have arisen on Earth and why biologists and physicists should work together to find a theory of life.
Her ideas could help decide what to do about artificial intelligence (SPOILER: The robots will take over, but it’s going to be OK). They might also help us find life on other planets.
Is there a constant battle between our immune system and pathogens? Does the fighting ever end? Does the immune system do more than just provide defense against pathogens?
Tune into this podcast to hear Art and Marty talk to Fred Tauber, a professor emeritus of medicine and philosophy at Boston University, about how the immune system does more than just protect our bodies from pathogens.
Fred has published a number of books on immunity and philosophy. Including his most recent book, "Immunity: the Evolution of an Idea," where he explores the ideas he discusses here in greater detail.
What is the connection between an organism's genes and its environment? Can the environment alter an organism's characteristics without altering its genetics? Can an organism alter its environment and change the course of its own evolution?
Tune into this podcast to hear Marty and Art talk to Massimo Pigliucci, a professor of philosophy at CUNY-City College in New York, about how the environment can alter an organism's physical characteristics without altering its genetics, and how our ability to alter our physical environment may have altered the course of human evolution.
Massimo began his career as an evolutionary biologist, and has published numerous scientific and philosophical journal articles and over 10 different books.
How do mantis shrimp punch as fast as a bullet… underwater? How do they break open one of the toughest materials on earth?
Tune into this podcast to hear Art and Marty talk to Sheila Patek about how mantis shrimp pack such a powerful punch and why we should care. For example, mantis shrimp hammers can be used hundreds of thousands of times to break open the tough shells of snails and clams, and this research may help inspire lightweight, heavy duty military armor.
Sheila studies the mechanics of ultrafast movements at Duke University. You may have seen her work featured recently by Science News (and numerous others) about the rules of animal fight clubs. But we can't talk about those.
How do diseases spread from animals to humans? Is it possible to forecast where disease outbreaks will occur and when they will blow up into major health crises?
Tune into this podcast to hear Marty and Art talk to Barbara Han about how we track infectious diseases and whether we'll ever be able to predict outbreaks. Han studies the conditions leading to disease outbreaks in humans at the Cary Institute of Ecosystem Studies in New York. Who knows, her research on forecasting disease outbreaks may even help predict and stop a zombie pandemic (think World War Z type scenario) from ever starting.

Is there a role for basic research in our society? Do scientists studying animals waste tax-payer money? How does learning about evolutionary biology benefit humans?
Tune in to this episode to hear Art and Marty talk to Carl Zimmer about the importance of basic research and the future of biology. Zimmer is an award-winning journalist for the New York Times, where he writes the weekly column, “Matter.” He has been a big proponent for furthering the public’s understanding of basic research, especially the importance of evolutionary biology. He is such a big deal that he even has a lovely species of tapeworm named after him (Acanthobothrium zimmeri)!

Is there a limit to animal size? Could Godzilla actually exist?
Tune into this episode to hear Art and Marty talk to Jon Harrison and Jim Brown.
Jon Harrison (Arizona State University) studies the physical limits to insect body size and furthered our understanding of the giant insects that once roamed our planet. Luckily for us, his research indicates that Mothra may never exist.
Jim Brown (University of New Mexico) famously put forth the universal quarter-power scaling law, which predicts how many ecological and evolutionary variables (including metabolism, life span, reproduction) of plants and animals change with body size. For example, his theory was able to explain the fact that all mammals average the same number of heartbeats (~ 1 billion) over their life time, regardless of how large they are (mice to elephants) or how long they live (3 years or 70 years)! Elephants hearts just beat really slow.
What is the role of random, stochastic events in biology? How does our body react to such events? Does the presence of random events in our brains give us the illusion of freewill?
Tune into this episode to hear Marty and Art talk to Denis Noble, an Emertis Professor at Oxford. Noble has written over 500 scientific articles and 11 books but may be most well known for developing the first mathematical model of heart cells in 1960. Recently, Noble published the book: “Dance to the Tune of Life,” where he notably discusses the necessity and importance of random events that occur within and between our genes, cells, tissues, and organs.
Why do we drink alcohol? Are we just primates looking for a fix?
Tune in to this episode to hear Art and Marty talk to Robert Dudley (not to be confused with the First Earl of Leicester of the same name). He is a renown expert in animal flight at UC Berkeley, but has recently begun studying drunken monkeys to understand our attraction to alcohol.
