Big Picture Science for Sept. 25, 2023 - Skeptic Check: Near Death Experiences

Big Picture Science - Skeptic Check: Near Death Experiences

Near death experiences can be profound and even life changing. People describe seeing bright lights, staring into the abyss, or meeting dead relatives. Many believe these experiences to be proof of an afterlife.

But now, scientists are studying these strange events and gaining insights into the brain and consciousness itself. Will we uncover the scientific underpinning of these near-death events?

Guests:
Steve Paulson - executive producer of To the Best of Our Knowledge for Wisconsin Public Radio
Sebastian Junger - journalist, filmmaker and author of “The Perfect Storm: A True Story of Men Against the Sea”
Christoph Koch - neuroscientist at the Allen Institute in Seattle and chief scientist of the Tiny Blue Dot Foundation in Santa Monica CaliforniaDaniel Kondziella - neuroscientist in the Department of Clinical Medicine at the University of Copenhagen

Big Picture Science for Sept. 18, 2023 - Into the Deep

Big Picture Science - Into the Deep

REPEAT
Have you ever heard worms arguing? Deep-sea scientists use hydrophones to eavesdrop on “mouth-fighting worms.” It’s one of the many ways scientists are trying to catalog the diversity of the deep oceans — estimated to be comparable to a rainforest.

But the clock is ticking. While vast expanses of the deep sea are still unexplored, mining companies are ready with dredging vehicles to strip mine the seafloor, potentially destroying rare and vulnerable ecosystems. Are we willing to eradicate an alien landscape that we haven’t yet visited?

Guests:

• Craig McClain - deep-sea and evolutionary biologist and ecologist, Executive Director of the Louisiana Universities Marine Consortium.
• Steve Haddock - senior scientist at the Monetary Bay Aquarium Research Institute, and co-author of a New York Times op-ed about the dangers of mining.
• Emily Hall - marine chemist at the Mote Marine Laboratory, Sarasota, Florida
• Chong Chen - deep sea biologist with the Japan Agency for Marine-Earth Science and Technology (JAMSTEC)

Big Picture Science for Sept. 11, 2023 - What’s a Few Degrees?

Big Picture Science - What’s a Few Degrees?

REPEAT
Brace yourself for heatwave “Lucifer.” Dangerous deadly heatwaves may soon be so common that we give them names, just like hurricanes. This is one of the dramatic consequences of just a few degrees rise in average temperatures.

Also coming: Massive heat “blobs” that form in the oceans and damage marine life, and powerful windstorms called “derechos” pummeling the Midwest.

Plus, are fungal pathogens adapting to hotter temperatures and breaching the 98.6 F thermal barrier that keeps them from infecting us?

Guests:

• Kathy Baughman McLeod – director and senior vice president of the Adrienne Arsht-Rockefeller Foundation Resilience Center at The Atlantic Council
• Pippa Moore – Marine ecologist at Newcastle University in the U.K.
• Ted Derouin – Michigan farmer
• Jeff Dukes – Ecologist and director of Purdue Climate Change Research Center at Purdue University.
• Arturo Casadevall – Molecular microbiologist and immunologist at the Johns Hopkins School of Medicine

Big Picture Science for Sept. 04, 2023 - Building a Space Colony

Big Picture Science - Building a Space Colony

REPEAT
Ready to become a space emigre? For half a century, visionaries have been talking about our future off-Earth – a speculative scenario in which many of us live in space colonies. So why haven’t we built them? Will the plans of billionaire space entrepreneurs to build settlements on Mars, or orbiting habitats that would be only minutes away from Earth, revive our long-held spacefaring dreams? And is having millions of people living off-Earth a solution to our problems… or an escape from them?

Guests:

• Marianne Dyson – Author and former NASA flight controller
• Emily St. John Mandel – Author, most recently of “Sea of Tranquility”
• John Adams – Deputy Director, Biosphere 2, University of Arizona
