Big Picture Science for Aug 03, 2026: Skeptic Check: The Body Electric

A stylized neuron surrounded by branching extensions. In the center, a bluish cell body has a round, purple nucleus, with many thin, glowing, threadlike branches radiating outward in all directions, representing dendrites and an axon. The background is very dark, and scattered around the neuron are several small, bright orange and purple glowing spots, suggesting electrical or chemical signals traveling between neurons.









Big Picture Science: Skeptic Check: The Body Electric

REPEAT
Electricity plays an important role in our everyday lives, including allowing our bodies to communicate internally. But some research claims electricity may be used to diagnose and treat disease? Could electric pulses one day replace medications?

We speak with experts about the growing field of bioelectric medicine and the evidence for electricity’s healing abilities. Their comments may shock you.

Big Picture Science for July 17, 2023 - Fantastic-er Voyage









Big Picture Science - Fantastic-er Voyage

(REPEAT)
Thinking small can sometimes achieve big things. A new generation of diminutive robots can enter our bodies and deal with medical problems such as intestinal blockages. But do we really want them swimming inside us, even if they’re promising to help? You might change your mind when you hear what else is cruising through our bloodstream: microplastics!

We take a trip into the human body, beginning with the story of those who first dared to open it up for medical purposes. But were the first surgeons really cavemen?

Guests:

  • Ira Rutkow – Surgeon and writer, and author of “Empire of the Scalpel: The History of Surgery”
  • Dick Vethaak – Emeritus professor of ecotoxicology, water quality and health at the Vrije Universiteit Amsterdam (Free University, Amsterdam) in The Netherlands
  • Li Zhang – Professor in the Department of Mechanical and Automation Engineering, The Chinese University of Hong Kong
  • Michael LaBarbera – Professor in organismal biology, anatomy and geophysical sciences, University of Chicago

Big Picture Science for Monday 11 May 2015 - A Fundy Thing Happened













Big Picture Science - A Fundy Thing Happened

Get ready for déjà vu as you listen to some of our favorite interviews from the past year. It’s our annual fundraising podcast. Come for the great interviews, stay for the great interviews. Lend us your support along the way.

What’s for dinner? Maybe Soylent. Made by … people! We do a taste test. Then meet your gut microbes. They control your health and even your mood.

Get tips on how to talk to aliens, why you should keep an eye on government surveillance, and the future of 3D printing human tissue. Also, why extraordinary beliefs persist – including Holocaust denial – despite the persistence of evidence to the contrary.

And, global perspective: why Ebola won’t be the next big pandemic but sea level rise could wipe out coasts along Florida and Thailand.

Plus, we imagine life hundreds of years ago for the renegades on the rough seas, and what the world would be like had the dinosaurs not gone extinct.

All this and more on a special Big Picture Science podcast!

Big Picture Science for Monday 06 April 2015 - Raising the Minimum Age

Image for Big Picture Science weekly radio show
Big Picture Science - Raising the Minimum Age

We all try to fight it: the inexorable march of time. The fountain of youth doesn’t exist, and all those wrinkle creams can’t help. But modern science is giving us new weapons in the fight against aging. So how far are we willing to go?

Hear when aging begins, a summary of the latest biotech research, and how a lab full of youthful worms might help humans stay healthy.

Also, a geneticist who takes a radical approach: collect the DNA that codes for longevity and restructure our genome. He finds inspiration – and perhaps genes as well – in the bi-centenarian bowhead whale.

But what if age really is mind over matter? A psychologist’s extraordinary thought experiment with septuagenarian men turns back the clock 20 years. Will it work on diseases such as cancer as well?

Big Picture Science for Monday 30 March 2015 - Hidden History

Image for Big Picture Science weekly radio show
Big Picture Science - Hidden History

Archeologists continue to hunt for the city of Atlantis, even though it may never have existed. But, what if it did? Its discovery would change ancient history. Sometimes when we dig around in the past, we can change our understanding of how we got to where we are.

We thought we had wrapped up the death of the dinosaurs: blame it on an asteroid. But evidence unearthed in Antarctica and elsewhere suggests the rock from space wasn’t the sole culprit.

Also, digging into our genetic past can turn up surprising – and sometimes uncomfortable truths – from ancestral origins to genes that code for disease. But do we always want to know?

Big Picture Science - Microbes: Resistance is Futile

You are what you eat. Whether you dine on kimchi, carnitas, or corn dogs determines which microbes live in your stomach. And gut microbes make up only part of your total microbiome.

Find out how your microbes are the brains-without-brains that affect your health and even your mood. Also, why you and your cohorts are closer than you thought: new research suggests that you swap and adopt bugs from your social set.

Plus, the philosophical questions that are arise when we realize that we have more microbial DNA than human DNA.

And a woman who skipped soap and shampoo for a month to see what would grow on her.

Big Picture Science - Skeptic Check: The Me in Measles

Wondering whether to vaccinate your children? The decision can feel like a shot in the dark if you don’t know how to evaluate risk. Find out why all of us succumb to the reasoning pitfalls of cognitive and omission bias, whether we’re saying no to vaccines or getting a tan on the beach.

Plus, an infectious disease expert on why it may take a dangerous resurgence of preventable diseases – measles, whooping cough, polio – to remind us that vaccines save lives.

Also, a quaint but real vaccine fear: that the 18th century smallpox vaccine, made from cowpox, could turn you into a cow!

It’s our monthly look at critical thinking … but don’t take our word for it!

Guests:
  • Paul Offit – Infectious disease specialist at the Children’s Hospital of Philadelphia
  • Neil deGrasse Tyson – Astrophysicist, director of the Hayden Planetarium in New York City

Big Picture Science for 07/28/14 - Replace What Ails You

Image for Big Picture Science weekly radio show
Big Picture Science - Replace What Ails You

Germs can make us sick, but we didn’t know about these puny pathogens prior to the end of the 19th century. Just the suggestion that a tiny bug could spread disease made eyes roll. Then came germ theory, sterilization, and antibiotics. It was a revolution in medicine. Now we’re on the cusp of another one. This time we may cure what ails us by replacing what ails us.

Bioengineers use advancements in stem cell therapy to grow red and white cells for human blood. Meanwhile, a breakthrough in 3D printing: scientists print blood vessels and say that human organs may be next.

Plus, implanting electronic grids to repair neural pathways. Future prosthetics wired to the brain may allow paralyzed limbs to move.

We begin with the story of the scientist who discovered the bacteria that caused tuberculosis, and the famous author who revealed that his cure for TB was a sham.

Are We Alone for 02/28/11 - Skeptic Check: Diluted Thinking?

Image for Are We Alone weekly radio show
Are We Alone - Skeptic Check: Diluted Thinking?

The weaker the mixture, the stronger the potency. That paradox is a central tenet of homeopathy. More than 200 years old and developed long before germ theory, the practice is the fastest growing form of alternative medicine worldwide.

Proponents say its diluted remedies cure disease. Most scientists maintain there’s nothing in homeopathic solution but water. We’ll hear the arguments, and also the role placebos might be playing in the cure.

Plus, skeptic Phil Plait voyages to the edge of the solar system where a new planet has been discovered … maybe!

And, consider our brains: the product of millions of years of evolution. So why aren’t we more consistent in our reasoning?

It’s Skeptic Check…. but don’t take our word for it.

Are We Alone - Rxs Get Personal

ENCORE Medicine’s back.. and this time it’s personal. Get ready to have your genome read… your brain scanned… and undergo a chemical analysis so detailed, it’ll reveal the Twinkie you had for lunch. Everyone’s different, and reading those differences at the level of the gene may provide a more accurate profile of health and how to treat disease. But are you ready to know what’s wrong with you?

Discover the future of personalized medicine with biologist Craig Venter, as well as a man who turned his body over to the new science. Learn what his tests revealed.

Plus, why stem cell research really is a horse race. And, why getting sick is sometimes the best thing.

Are We Alone - Skeptic Check: Mind Your Body

Popping a pill may help when you’re sick… but maybe not for the reasons you think. Sugar pills – placebos – cure illness better than prescription pills in as many as half of all cases in clinical trials … and the placebo effect is getting stronger.

Plus, the safety – or otherwise – of electromagnetic waves, and the “electro-sensitive” refugees who have built a camp to protect themselves from waves they say are causing pain. Is it all in their minds?

And, New York Times reporter Dennis Overbye joins Phil Plait on the latest lapse in critically-thinking brains – a wild idea that may not be so loony: namely, could a cosmic censor from the future be thwarting efforts to find the Higgs boson?
