We can now follow where Monarch butterflies go when they leave our gardens with tiny sensors that track their impressive 3,000-mile migrations from Canada to Mexico. The significant challenges that the journey poses are depicted in a new science exhibit at the American Museum of Natural History featuring artwork by Mad Magazine illustrator and environmentalist Peter Kuper. Their plight highlights the threats that chemicals and habitat loss pose to all insects, but all is not dire. Surprising research into how Monarchs protect themselves from disease shows the remarkable self-healing capacities of not only our colorful, vital pollinators but a diversity of species, from birds to dogs to chimpanzees.

Guests:

Sean Decatur – President of the American Museum of Natural History in New York City

Jessica Ware – Entomologist, Chair of the Division of Invertebrate Zoology, Curator, Monarch’s Journey at the American Museum of Natural History

Peter Kuper – Graphic novelist whose work appears regularly in Charlie Hebdo, The New Yorker, The Nation, and Mad Magazine, where he has written and illustrated “Spy vs. Spy” since 1997, illustrator of the AMNH exhibition, Monarch’s Journey

Mark Moffett – Tropical biologist, research associate at the National Museum of Natural History in the Smithsonian Institution, visiting scholar, Department of Human Evolution, Harvard University

Jaap de Roode – Biologist, Emory University, author of “Doctors by Nature: How Ants, Apes, and Other Animals Heal Themselves"

Carbon dioxide is more than an industrial pollutant driving climate change. The gas also played a pivotal part in the dramatic story of the beginning of all life. Starting in the ocean depths, dissolved CO2 commingled in a turbulent mix of chemicals heated by hydrothermal vents may have kickstarted carbon-based life. As the planet’s thermostat, carbon dioxide has taken the Earth on wild temperature swings, from sweltering toxic hothouses that drove mass extinctions to the frigid Snowball Earth from which early life barely escaped. With life’s growing complexity, CO2’s role evolved. Exhaled by animals and enlisted by plants in photosynthesis, the gas eventually earned its discordant reputation when belched by industrial chimneys. Now, burning fossil fuels have us playing with fire as we test the limit of our stable climate upon which human civilization has flourished.

Guest:

Peter Brannen – science journalist and author of “The Story of CO2 is the Story of Everything; How Carbon Dioxide Made Our World.”

How did scientists learn to peer inside the atom? In this preview from the BBC's In Our Time, physicist Harry Cliff tells the story of the birth of the particle accelerator, from Ernest Rutherford's challenge to unlock the secrets of matter to the race to build the first machines capable of doing it.

Featuring homemade high-voltage experiments, scientific rivalry, and one memorable encounter involving a dead rat and a lot of electricity, it's a fascinating glimpse into the early days of modern particle physics.In Our Time delivers a world-class seminar, every week. From Philosophy to Physics, Pre-Raphaelites to Pharaohs, each week Misha Glenny is joined by a team of expert guests to discuss the ideas, people and events that have shaped our world.

Telescopes are like light buckets. The bigger the telescope, the more light collected for astronomers to observe. With recent advances in technology, amateur astronomers can join professionals for a chance to observe stellar nurseries and exoplanets many light-years away. But as our capabilities increase, so do the mysteries, including those around high-energy bursts coming from an otherwise unremarkable part of the universe. Understanding fast radio bursts could turn physics on its head.

From the Vera Rubin Telescope in Chile to the backyard instruments of amateur astronomers, we share what new things we might learn about stars, the Earth, exoplanets, and the potential for life on other worlds.

Guests:

Clare Higgs – Astronomer working with the public outreach team for the Vera Rubin Observatory

Franck Marchis – Senior astronomer and director of citizen science at the SETI Institute, chief science officer and co-founder of Unistellar

Amanda Cook – Postdoctoral fellow at McGill University and member of the CHIME/FRB Collaboration

We admire the ornamental beauty of flowers in a garden, but those blooms are more than lush color. The seemingly fragile, delicate petals are part of a resilient, adaptive innovation that arrived on the scene 250 million years ago and transformed life on the planet. Much life, including us, would not have evolved without flowering planets. Yet the power of the petal is often overlooked. How does our perspective on nature’s web change if we give flowers the credit they deserve? Celebrated biologist David Haskell shares the story of how nature’s revolutionaries evolved their vibrant hues and intoxicating scents to lure bees, butterflies and other animals into cooperative partnerships.

Guest:

David George Haskell – biologist, professor at Emory University, and author of “How Flowers Made Our World: The Story of Nature’s Revolutionaries"
