Insect populations are declining. But before you say “good riddance,” consider that insects are the cornerstone of many ecosystems. They are dinner for numerous animal species and are essential pollinators. Mammals are loved, but they are not indispensable. Insects are.
Meanwhile, marvel at the extraordinary capabilities of some insects. The zany aerial maneuvers of the fly are studied by pilots. And, contrary to the bad press, cockroaches are very clean creatures. Also, take a listen as we host some Madagascar hissing cockroaches in our studio (yes, they audibly hiss).
Plus, how insects first evolved … and the challenges in controlling lethal ones. Are genetically-engineering mosquitoes the best way to combat malaria?
Guests:


 Erica McAlister – Entomologist, Senior Curator of diptera in the Department of Entomology, Natural History Museum in London, author of “The Secret Life of Flies”


 Jessica Ware – Evolutionary biologist and entomologist at Rutgers University


Anthony James – Vector biologist, University of California, Irvine


 Lauren Esposito – Arachnologist, California Academy of Sciences, San Francisco

Science

Birds have it going on. Many of these winged dinosaurs delight us with their song and brilliant plumage. Migratory birds travel thousands of miles in a display of endurance that would make an Olympic athlete gasp.
We inquire about these daunting migrations and how birds can fly for days without rest. And what can we do to save disappearing species? Will digital tracking technology help? Plus, how 19th century bird-lovers, appalled by feathered hats, started the modern conservation movement.
Guests:
Scott Weidensaul – Ornithologist and naturalist and author of “A World on the Wing: the Global Odyssey of Migratory Birds.”
Kassandra Ford – Doctoral candidate in evolutionary biology at the University of Louisiana at Lafayette.
Michelle Nijhuis – Science journalist and author of “Beloved Beasts: Fighting for Life in an Age of Extinction.”

For the Birds*

The zombie eco-thriller “The Last of Us” has alerted us to the threats posed by fungi. But the show is not entirely science fiction. Our vulnerability to pathogenic fungi is more real than many people imagine. 
Find out what human activity drives global fungal threats, including their menace to food crops and many other species. Our high body temperature has long kept lethal fungi in check; but will climate change cause fungi to adapt to warmer temperatures and threaten our health? 
Plus, a radically new way to think about these organisms, how they make all life possible, and how we might find balance again.
Guests:
Emily Monosson – Toxicologist who writes about changes in the natural world. A member of the Ronin Institute and a professor at the University of Massachusetts, Amherst, she is the author of “Blight: Fungi and the Coming Pandemic.”
Arturo Casadevall – Microbiologist, immunologist, professor of medicine at Johns Hopkins School of Medicine.
Michael Hathaway – Anthropologist, director of the Asian Studies Center at Simon Fraser University in Vancouver, Canada, and author of “What a Mushroom Lives For.”

Fungi Fear*

Drinking a cup of coffee is how billions of people wake up every morning. But climate change is threatening this popular beverage. Over 60% of the world’s coffee species are at risk of extinction. Scientists are searching for solutions, including hunting for wild, forgotten coffee species that are more resilient to our shifting climate. Find out how the chemistry of coffee can help us brew coffee alternatives, and how coffee grounds can be part of building a sustainable future.
Guests:
Christopher Hendon - Assistant Professor of Computational Materials Chemistry, University of Oregon
Shannon Kilmartin-Lynch - Associate Professor of Civil Engineering, Monash University, Australia
Aaron Davis - Senior Research Leader of Crops and Global Change, Royal Botanical Gardens, Kew

Coffee of the Future

The Great North American Solar Eclipse will trace a path of shadow across Mexico and 13 U.S. States on April 8th. Phil Plait, also known as The Bad Astronomer, joins the show for an extended interview covering a wide-range of topics, such as his excitement about the eclipse, the Pentagon’s most recent UFO report, and some of the most persistent moon landing conspiracy theories.
Guest:
Phil Plait – aka the Bad Astronomer, former astronomer on Hubble, teacher, lecturer, and debunker of conspiracy theories. He is also the author of a new book “Under Alien Skies: A Sightseer’s Guide to the Universe.”

When the Moon Hits Your Eye

Asteroids are rich in precious metals and other valuable resources. But mining them presents considerable challenges. We discuss these, and consider how these spinning, rocky resources might be the key to a space-faring future. But an economist points out the consequences of bringing material back to Earth, and a scientist raises an ethical question; do we have an obligation to keep the asteroids intact for science?
 Guests:
Jim Bell - Planetary scientist in the School of Earth and Space Exploration at Arizona State University.
Martin Elvis - Astronomer and author of “Asteroids: How Love, Fear, and Greed Will Determine Our Future in Space.”
Ian Lange - Economist and associate professor at the Colorado School of Mines and author of a paper on the feasibility of asteroid mining.
