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

Big Picture Science for Aug 28, 2023 - Talk the Walk

 

Big Picture Science - Talk the Walk

REPEAT
Birds and bees do it … and so do fish. In a discovery that highlights the adaptive benefits of walking, scientists have discovered fish that can walk on land. Not fin-flap their bodies, mind you, but ambulate like reptiles.

And speaking of which, new research shows that T Rex, the biggest reptile of them all, wasn’t a sprinter, but could be an efficient hunter by outwalking its prey.

Find out the advantage of legging it, and how human bipedalism stacks up. Not only is walking good for our bodies and brains, but not walking can change your personality and adversely affect your health.

Guests:

• Hans Larsson – Paleontologist and biologist, and Director of the Redpath Museum at McGill University in Montréal.
• Shane O’Mara – Neuroscientist and professor of experimental brain research at Trinity College Dublin. He is the author of “In Praise of Walking.”
• Brooke Flammang – Biologist at the New Jersey Institute of Technology.

Big Picture Science - Granting Immunity

REPEAT
“Diversity or die” could be your new health mantra. Don’t boost your immune system, cultivate it! Like a garden, your body’s defenses benefit from species diversity.  Find out why multiple strains of microbes, engaged in a delicate ballet with your T-cells, join internal fungi in combatting disease.

Big Picture Science for Aug 07, 2023 - Skeptic Check: UFO Conspiracy

Big Picture Science - Skeptic Check: UFO Conspiracy

UFOs are back. This time they’ve landed on Capitol Hill in the form of a public, congressional hearing. We watched the hearing with great interest, but felt dissatisfied when it came to evidence. Claims that the government has alien technology are obviously tantalizing. So tantalizing, in fact, that it’s easy to overlook logical fallacies in how these claims are presented. We identify a few of the missteps. But what would convince you that the government is aware of alien visitation? Is the word of an authority figure all we need to accept that “they’re here?” 

Guests:

• Benjamin Radford - Research fellow with the Committee for Skeptical Inquiry
• Nadia Drake - Science journalist and member of NASA’s UAP group
• James McGaha - Retired military pilot and astronomer he's a longtime investigator of UFO reports and claims and he's a scientific consultant to the Committee for Skeptical Inquiry
• Mick West - A skeptical investigator who looks at claims of UFOs

Big Picture Science for July 31, 2023 - We’ll Always Have Parasites

Big Picture Science - We’ll Always Have Parasites

Imagine tapeworms longer than the height of an adult human. Or microbes that turn their hosts into zombies. If the revulsion they induce doesn’t do it, the sheer number of parasites force us to pay attention. They are the most abundant form of animal life on Earth. Parasites can cause untold human suffering, like those that cause African River Blindness or Lyme disease, but their presence is also a sign of a health ecosystem. A parasitologist whose lab contains the largest parasite collection in the world gives us the ultimate inside story about these organisms.

Guest:

Scott Gardner - curator of parasites in the H.W. Manter Laboratory of Parasitology at the University of Nebraska State Museum, one of the largest collections of parasites in the world, and professor of biological sciences at University of Nebraska. Co-author of Parasites: The Inside Story.

Big Picture Science for July 24, 2023 - Measure For Measure

Big Picture Science - Measure For Measure

Whether in miles or pounds, meters or kilograms, we take daily measure out our lives. But how did these units ever come to be, and why do we want to change them? From light-years to leap seconds, we look at the history of efforts to quantify our lives and why there’s always room for greater precision.

Plus, we debate the virtues of staying imperial measurements vs. going metric.
