Big Picture Science

Our information age is increasingly the disinformation age. The spread of lies and conspiracy theories has created competing experiences of reality. Facts are often useless for changing minds or even making compelling arguments. In this episode, author Naomi Klein and science philosopher Lee McIntyre discuss why the goal – not simply the byproduct - of spreading disinformation is to polarize society. They also offer ideas about how we might find our way back to a shared objective truth.  

Guests:

Naomi Klein - Associate professor of Geography at the University of British Columbia and a co-director at the Center for Climate Justice. Author of Doppelganger: A Trip Into the Mirror World

Lee McIntyre - Philosopher of science and a research fellow at the Center for Philosophy and the History of Science at Boston University, and author of Post-Truth and On Disinformation.

“To live is to count and to count is to calculate.” But before we plugged in the computer to express this ethos, we pulled out the pocket calculator. It became a monarch of mathematics that sparked a computing revolution. But it’s not the only deceptively modest innovation that changed how we work and live. Find out how sewing a scrap of fabric into clothing helped define private life and how adding lines to paper helped build an Empire. Plus, does every invention entail irrevocable cultural loss?

Guests:

Keith Houston – author of “Empire of the Sum: The Rise and Reign of the Pocket Calculator.”

Hannah Carlson – teaches dress history and material culture at the Rhode Island School of Design, author of “Pockets: An Intimate History of How We Keep Things Close.”

The SETI Institute’s search for alien biosignatures and technosignatures depends on radio telescopes. You may have seen the stunning photos of massive telescope arrays in the desert, but what types of alien signals might help researchers actually detect with those giant dishes?

In this fourth episode, Brian Edwards talks with physicist Chenoa Tremblay, a COSMIC Project Scientist who is based at the Very Large Array in New Mexico. They dig into the important role radio telescopes play in SETI, how powerful computers have supercharged the search for life off Earth, and imagine what kinds of biosignatures and technosignatures of alien life we are most likely to find.

Just because something is invisible doesn’t mean it isn’t there. We can’t see gases in our atmosphere, such as carbon dioxide, oxygen, and nitrogen, but we benefit from their presence with every breath we take. From the bubbles that effervesce in soda to the vapors that turn engines, gases are part of our lives. They fill our lungs, give birth to stars, and… well, how would we spot a good diner without glowing neon? In this episode, a materials scientist shares the history of some gaseous substances that we don’t usually see, but that make up our world.

Guest:

Mark Miodownik – Professor of materials and society at the University College London and the author of “It’s a Gas: The Sublime and Elusive Elements That Expand Our World.”

Imagine life without animals, trees, and fungi. The world would look very different. But while the first life was surely single-celled, we don’t know just how it evolved to multicellular organisms. Two long-term experiments hope to find out, and one has been running for more than 35 years. Hear about the moment scientists watched evolution take off in the lab, and how directed evolution was used to create a multicellular organism. Also, how single embryonic cells become humans, and what all of this says about the possibility of life on other worlds.

Guests:

Jeff Barrick – molecular scientist at the University of Texas at Austin where his lab oversees the Long-Term Evolution Experiment that’s been running since 1988.

How do we know where to look for life on other planets? SETI scientists use analog sites on Earth, not only to study how life has evolved here, but the geological conditions that made it possible. Devon Island in Canada is one such analog. It's been called Mars on Earth. 

In this third episode, Gary Niederhoff talks with planetary scientist Pascal Lee, co-founder of The Mars Institute, and principal investigator of the Haughton-Mars Project at NASA Ames Research Center in Mountain View, California. They discuss how a remote arctic island offers clues about how liquid water once flowed on Mars, why the moons of the Red Planet are so mysterious, and Pascal’s discovery of a heretofore unrecognized Martian volcano in 2024.

You interact with about two-thirds of the elements of the periodic table every day. Some, like carbon, oxygen, and nitrogen, make up our bodies and the air we breathe. Yet there is also a class of elements so unstable they can only be made in a lab. These superheavy elements are the purview of a small group stretching the boundaries of chemistry. Can they extend the periodic table beyond the 118 in it now? Find out scientists are using particle accelerators to create element 120 and why they’ve skipped over element 119. Plus, if an element exists for only a fraction of a second in the lab, can we still say that counts as existing?

Guests:

Mark Miodownik – professor of materials and society at the University of College London and the author of “It’s a Gas: The Sublime and Elusive Elements That Expand Our World.”

A thousand years ago, most people didn’t own a single book. The only way to access knowledge was to consult their memory. 

But technology – from paper to hard drives – has permitted us to free our brains from remembering countless facts. Alphabetization and the simple filing cabinet have helped to systematize and save information we might need someday.

But now that we can Google just about any subject, have we lost the ability to memorize information? Does this make our brains better or worse?

Guests:

Judith Flanders – Historian and author, most recently of A Place for Everything: The Curious History of Alphabetical Order

Craig Robertson – Professor of Media Studies, Northeastern University and author of The Filing Cabinet: A Vertical History of Information

What is life? Even as the search for life in the universe evolves, surprisingly, there is no consensus on what life is. We must consider hunting for life not as we know it. 

The existence of extremophiles on Earth has broadened the types of environments in which we might look for life elsewhere in our solar system. And recent missions to dwarf planets has shown that our solar system is replete with the geology that might harbor biology.

In this second episode, Shannon Geary talks with astrobiologist Nathalie Cabrol, the director of the Carl Sagan Center for Research at the SETI Institute about her early interest in astrobiology, meeting Carl Sagan, and the evolving definition of life.

The idea that the universe is made of tiny vibrating strings was once the science theory du jour. String theory promised to unite the disparate theories describing particles and gravity, and many people, not just scientists, were optimistic that a theory of everything might be within our grasp. But here we are, many years later, and string theory doesn’t seem to have delivered on its initial promise. What happened? We consider the science around string theory in this episode of Skeptic Check.

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.

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.

We have too much “bad fire.” Not only destructive wildfires, but the combustion that powers our automobiles and provides our electricity has generated a worrying rise in atmospheric carbon dioxide. And that is driving climate change which is adding to the frequency of megafires. Now we’re seeing those effects in “fire-clouds,” pyrocumulonimbus events.

But there’s such a thing as “good fire.” Indigenous peoples managed the land with controlled fires, reaped the benefits of doing so, and they’re bringing them back.

So after millions of years of controlling fire, is it time for us to revisit our attitudes and policies, not just with regard to combustion, but how we manage our wildfires?

Before everything could come up roses, there had to be a primordial flower – the mother, and father, of all flowers. Now scientists are on the hunt for it. The eFlower project aims to explain the sudden appearance of flowering plants in the fossil record, what Darwin called an “abominable mystery.”

Meanwhile, ancient flowers encased in amber or preserved in tar are providing clues about how ecosystems might respond to changing climates. And, although it was honed by evolution for billions of years, can we make photosynthesis more efficient and help forestall a global food crisis?

They’re cute and cuddly. But they can also be obnoxious.

Science writer Mary Roach has numerous tales about how our animal friends don’t always bow to their human overlords and behave the way we’d want. The resulting encounters, such as when gulls disrupt the Vatican’s Easter mass, make for amusing stories. But others, such as wolves threatening farmers’ livestock, can be tragic.

We hear what happens at the messy crossroads of human and wildlife encounters.

Ever heard of a beauty quark? How about a glueball? Physics is full of weird particles that leave many of us scratching our heads. But these tiny particles make up everything in the quantum world and in us and are the basis of the fundamental scientific theory called The Standard Model. But it doesn’t explain everything. It can’t account for dark matter or dark energy, for example. We find out whether new physics experiments might force us to rewrite the Standard Model. Plus, we discuss a NASA proposal to fly spacecraft close to the sun in search of new physics.

Has children’s play become too safe? Research suggests that efforts to prioritize safety harms children’s mental and physical development during play and contribute to anxiety. One solution: introduce risk into play. We visit an adventure playground where kids play unsupervised with anything from scraps of metal to hammers and nails. Plus, what are the evolutionary benefits of play? After all, we’re not the only species who like to roughhouse, sled, or chase balls. And, reclaiming play for those who have outgrown recess.

It was a radical idea a century ago, when Einstein said space and time can be bent, and gravity was really geometry. We hear how his theories inspire young minds even today.

At small scales, different rules apply: quantum mechanics and the Standard Model for particles. New experiments suggest that muons – cousins of the electron – may be telling us that the Standard Model is wrong. Also, where the physics of both the large and small apply, and why black holes have no hair.

You are getting sleeeepy and open to suggestion. But is that how hypnotism works? And does it really open up a portal to the unconscious mind? Hypnotism can be an effective therapeutic tool, and some scientists suggest replacing opioids with hypnosis for pain relief. And yet, the performance aspect of hypnotism often seems at odds with the idea of it being an effective treatment. 

In our regular look at critical thinking, Skeptic Check, we ask what part of hypnotism is real and what is an illusion. Plus, we discuss how the swinging watch became hypnotism’s irksome trademark.

By one estimate we spend a fifth of our lives watching movies or TV. In fact, we consume entertainment almost as habitually as we eat or sleep, activities that receive scientific scrutiny and study. So why not consider the effects that watching movies and TV have on our minds and bodies too? When we do, we find that they are not mere escapism. A data scientist reveals why we are what we watch, and how scientists and filmmakers work, often with competing agendas, to create sci-fi entertainment.

Maybe you don’t remember the days of the earliest coal-fired stoves. They changed domestic life, and that changed society. We take you back to that era, and to millennia prior when iron was first smelt, and even earlier, when axe-handles were first fashioned from wood, as we explore how three essential materials profoundly transformed society. 

We were once excited about coal’s promise to provide cheap energy, and how iron would lead to indestructible bridges, ships, and buildings. But they also caused some unintended problems: destruction of forests, greenhouse gases and corrosion. Did we foresee where the use of wood, coal, and iron would lead? What lessons do they offer for our future?

Guests:

Jonathan Waldman – Author of Rust: The Longest War.

Ruth Goodman – Historian of British social customs, presenter of a number of BBC television series, including Tudor Monastery Farm, and the author of The Domestic Revolution: How the Introduction of Coal into Victorian Homes Changed Everything.

Roland Ennos – Professor of biological sciences at the University of Hull and author of The Age of Wood: Our Most Useful Material and the Construction of Civilization.

After helping to sequence the human genome more than twenty years ago, biochemist Craig Venter seemed to recede from the public eye. But he hadn’t retired. He had gone to sea and taken his revolutionary sequencing tools with him. We chatted with him about his multi-year voyage aboard the research vessel Sorcerer II, its parallels to Darwin’s voyage, and the surprising discoveries his team made about the sheer number and diversity of marine microbes and their roles in ocean ecosystems.

Guests:

Craig Venter - Genomicist, biochemist, founder of the J. Craig Venter Institute, and co-author of “The Voyage of Sorcerer II: The Expedition that Unlocked the Secrets of the Ocean’s Microbiome.”

Our information age is increasingly the disinformation age. The spread of lies and conspiracy theories has created competing experiences of reality. Facts are often useless for changing minds or even making compelling arguments. In this episode, author Naomi Klein and science philosopher Lee McIntyre discuss why the goal – not simply the byproduct - of spreading disinformation is to polarize society. They also offer ideas about how we might find our way back to a shared objective truth.  

Guests:

Naomi Klein - Associate professor of Geography at the University of British Columbia and a co-director at the Center for Climate Justice. Author of Doppelganger: A Trip Into the Mirror World

Lee McIntyre - Philosopher of science and a research fellow at the Center for Philosophy and the History of Science at Boston University, and author of Post-Truth and On Disinformation.

Nothing lasts forever. Even the universe has several possible endings. Will there be a dramatic Big Rip or a Big Chill­–also known as the heat death of the universe–in trillions of years? Or will vacuum decay, which could theoretically happen at any moment, do us in? Perhaps the death of a tiny particle – the proton – will bring about the end.

We contemplate big picture endings in this episode, and whether one could be brought about by our own machine creations.

T-Rex is having an identity crisis. Rocking the world of paleontology is the claim that Rex was not one species, but actually three. It’s not the first time that this particular dino has forced us to revise our understanding of the past. The discovery of the first T-Rex fossil in the 19th century taught humanity a scary lesson: species eventually go extinct. If it happened to this seemingly invincible apex predator, it could happen to us too.

Hear how the amateur fossil hunter Barnum Brown’s discovery of T-Rex changed our understanding of ourselves, and the epilogue to the dinosaur era: how our mammalian relatives survived the potential extinction bottleneck of an asteroid impact.

Owls are both the most accessible and elusive of birds. Every child can recognize one, but you’ll be lucky to spot an owl in a tree, even if you’re looking straight at it. Besides their camouflage and silent flight, these mostly nocturnal birds, with their amazing vision and hearing, are most at home in the dead of night, a time humans find alien and scary. Ecologist Carl Safina got to know an injured baby screech owl well. Their relationship saved the owl’s life and gave Safina insider’s wisdom about these aerial hunters of the night.

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?”

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.

Crowded subway driving you crazy? Sick of the marathon-length grocery store line? Wish you had a hovercraft to float over traffic? If you are itching to hightail it to an isolated cabin in the woods, remember, we evolved to be together. Humans are not only social, we’re driven to care for one another, even those outside our immediate family.  

We look at some of the reasons why this is so – from the increase in valuable communication within social groups to the power of the hormone oxytocin. Plus, how our willingness to tolerate anonymity, a condition which allows societies to grow, has a parallel in ant supercolonies.

We have too much “bad fire.” Not only destructive wildfires, but the combustion that powers our automobiles and provides our electricity has generated a worrying rise in atmospheric carbon dioxide. And that is driving climate change which is adding to the frequency of megafires. Now we’re seeing those effects in “fire-clouds,” pyrocumulonimbus events.

But there’s such a thing as “good fire.” Indigenous peoples managed the land with controlled fires, reaped the benefits of doing so, and they’re bringing them back.

So after millions of years of controlling fire, is it time for us to revisit our attitudes and policies, not just with regard to combustion, but how we manage our wildfires?

In 1915, Endurance, the ship that took Ernest Shackleton to the Antarctic, was slowly crushed and sank. Shackleton, and the 28 men he brought with him, were camped on the ice near the ship, and watched helplessly as their transport went to a watery grave, two miles down. 

But a recent expedition has found the Endurance, taking the world back to the last hurrah of the heroic age of polar expedition. How was it found, and what will be done with it?

Also, while feats of exploration inspire TV shows and magazine articles, do they have other functions in society? Is modern exploration more than just a nice thing to do?

We go to the bottom of the world on “Finding Endurance.”

Guests:

Michael Smith – Author and journalist. His book: “Shackleton: By Endurance We Conquer”

Christian Katlein – Sea ice physicist

Hosted by Ash Kelley and Alaina Urquhart from the hit show Morbid.

When 90-year-old Laurence Pilgeram drops dead on the sidewalk outside his condo, you might think that’s the end of his story. But, really, it’s just the beginning. Because Laurence and others like him have signed up to be frozen and brought back to life in the future. And that belief will pull multiple generations of the Pilgeram family into a cryonics soap opera filled with dead pets, gold coins, grenades, fist fights, mysterious packages, family feuds, Hall of Fame baseball legends, and frozen heads — lots of frozen heads. From Wondery, comes a story about life, death, and what comes next.

Catalytic converters are disappearing. If you’ve had yours stolen, you know that precious and rare earth metals are valuable. But these metals are in great demand for things other than converters, such as batteries for electric cars, wind farms and solar panels.

We need rare earth metals to combat climate change, but where to get them? Could we find substitutes?

One activity that could be in our future: Deep sea mining. But it’s controversial. Can one company’s plan to mitigate environmental harm help?

Climate change isn’t waiting for us to act. We’ve missed several deadlines to mitigate the dangers of this existential threat, which suggests we prefer to avert our gaze rather than deal with the problem. It’s similar to the way society reacts to an incoming comet in the movie “Don’t Look Up!” 

As a major Antarctic ice sheet shows signs of collapse, it’s no wonder we feel some “climate anxiety.” Can we leverage this emotion to spur action? That, and where hope lies, in this episode.

Animals experience the world differently. There are insects that can see ultraviolet light, while some snakes can hunt in the dark thanks to their ability to sense infrared. Such differences are not restricted to vision: Elephants can hear subsonic sounds, birds navigate by magnetism, and your dog lives in a world marked by odors. In this episode, we speak to science journalist Ed Yong about how other creatures sense the world. Could we ever understand what it’s like to have the hearing of a bat or the sight of a hawk?

5G, the latest mobile network standard, is coming. As new cell towers sprout around the world, do we know enough to confidently claim that this new technology is safe? After all, older networking standards relied on microwaves, radiation which has wavelengths of inches to a foot or so. 5G operates at much higher frequencies, with millimeter wavelengths.

Some are worried that being subjected to millimeter radiation could cause cancers. But what does science say? 5G: the promise and the perils.

A century ago, British archaeologist Howard Carter opened the only surviving intact tomb from ancient Egypt. Inside was the mummy of the boy king Tutankhamun, together with “wonderful things” including a solid gold mask.

Treasure from King Tut’s crypt has been viewed both in person and virtually by many people since. We ask what about Egyptian civilization so captivates us, thousands of years later. Also, how new technology from modern physics allows researchers to “X-Ray” the pyramids to find hidden chambers.

Modern technology is great, but could we be losing control? As our world becomes more crowded and demands for resources are greater, some people worry about humanity’s uncertain prospects. An eminent cosmologist considers globe-altering developments such as climate change and artificial intelligence. Will we be able to stave off serious threats to our future?

There’s also another possible source of danger: our trendy digital aids. We seem all-too-willing to let algorithms classify and define our wants, our needs, and our behavior. Instead of using technology, are we being used by it – to inadvertently become social media’s product? 

And while we may be skittish about the increased data our technology collects, one sci-fi writer imagines a future in which information is a pervasive and freely available commodity.

A new theory about life’s origins updates Darwin’s warm little pond. Scientists say they’ve created the building blocks of biology in steaming hot springs. Meanwhile, we visit a NASA lab where scientists simulate deep-sea vent chemistry to produce the type of environment that might spawn life. Which site is best suited for producing biology from chemistry?

Find out how the conditions of the early Earth were different from today, how meteors seeded Earth with organics, and a provocative idea that life arose as an inevitable consequence of matter shape-shifting to dissipate heat. Could physics be the driving force behind life’s emergence?

A radical plan could solve a historic global health inequity. Countries in the global south who waited for more than a year for ample supplies of Covid vaccines have banded together to make mRNA vaccines locally. If successful, they could end a dangerous dependency on wealthy nations and help stop pandemics before they start.

In a special episode, supported by the Pulitzer Center, journalist Amy Maxmen shares her reporting from southern Africa about the inspiring project led by the WHO that’s made fast progress. But it could fail, and a global imbalance will remain, if Big Pharma has its way. Find out what’s at stake.

Declining biodiversity is a problem as fraught as climate change.

Loss of habitat, monoculture crops, and the damming of waterways all lead to massive species extinction. They tear at life’s delicate web, and threaten a balance established by four billion years of evolution.

Can we reassess our relationship to Nature? We consider logging efforts that make elephants part of the work force, and how to leverage the cooperative behavior of trees.

Becoming Nature’s ally, rather than its enemy.

A thousand years ago, most people didn’t own a single book. The only way to access knowledge was to consult their memory. 

But technology – from paper to hard drives – has permitted us to free our brains from remembering countless facts. Alphabetization and the simple filing cabinet have helped to systematize and save information we might need someday.

But now that we can Google just about any subject, have we lost the ability to memorize information? Does this make our brains better or worse?

When a Google software engineer claimed that a piece of chatbot software was sentient, it was a major story. Just like your dog is sentient, could it be that some computer code – a chatbot system called LaMDA – has feelings?

But was it truly sentient, or was it pulling algorithmic wool over our eyes? Were we simply being fooled by high-tech mimicry? In this, our regular look at critical thinking: Skeptic Check, we ask what is the evidence that this system is sentient. Also, even A.I. that’s not sentient can still be powerful – and that has serious implications.

T-Rex is having an identity crisis. Rocking the world of paleontology is the claim that Rex was not one species, but actually three. It’s not the first time that this particular dino has forced us to revise our understanding of the past. The discovery of the first T-Rex fossil in the 19th century taught humanity a scary lesson: species eventually go extinct. If it happened to this seemingly invincible apex predator, it could happen to us too.

Hear how the amateur fossil hunter Barnum Brown’s discovery of T-Rex changed our understanding of ourselves, and the epilogue to the dinosaur era: how our mammalian relatives survived the potential extinction bottleneck of an asteroid impact.

They’re cute and cuddly. But they can also be obnoxious.

Science writer Mary Roach has numerous tales about how our animal friends don’t always bow to their human overlords and behave the way we’d want. The resulting encounters, such as when gulls disrupt the Vatican’s Easter mass, make for amusing stories. But others, such as wolves threatening farmers’ livestock, can be tragic.

We hear what happens at the messy crossroads of human and wildlife encounters.

It was a radical idea a century ago, when Einstein said space and time can be bent, and gravity was really geometry. We hear how his theories inspire young minds even today.

At small scales, different rules apply: quantum mechanics and the Standard Model for particles. New experiments suggest that muons – cousins of the electron – may be telling us that the Standard Model is wrong. Also, where the physics of both the large and small apply, and why black holes have no hair.

Sexist snow plowing? Data that guide everything from snow removal schedules to heart research often fail to consider gender. In these cases, “reference man” stands in for “average human.” Human bias also infects artificial intelligence, with speech recognition triggered only by male voices and facial recognition that can’t see black faces. We question the assumptions baked into these numbers and algorithms.

Above the Arctic Circle, much of the land is underlaid by permafrost. But climate change is causing it to thaw. This is not good news for the planet. 

As the carbon rich ground warms, microbes start to feast… releasing greenhouse gases that will warm the Earth even more.

Another possible downside was envisioned by a science-fiction author. Could ancient pathogens–released from the permafrost’s icy grip–cause new pandemics? We investigate what happens when the far north defrosts.

Every second, lightning strikes 50 to 100 times somewhere. It can wreak havoc by starting wildfires and sometimes killing people. But lightning also produces a form of nitrogen that’s essential to vegetation. In this episode, we talk about the nature of these dramatic sparks. Ben Franklin established their electric origin, so what do we still not know? Also, why the frequency of lightning strikes is increasing in some parts of the world. And, what to do if you find someone hit by lightning.

Your shower pipes are alive. So are your sinks, books, and floorboards. New studies of our homes are revealing just what species live there – in the thousands, from bacteria to flies to millipedes. Meanwhile, life keeps surprising us by popping up in other unexpected places: the deep biosphere houses the majority of the world’s bacteria and the Arctic tundra has kept worms frozen, but alive, for 40,000 years.

We embrace the multitude of life living on us, in us, and – as it turns out – in every possible ecological niche. Most of it is harmless, some is beneficial, and it’s all testament to the amazing diversity and adaptability of life. In addition, the hardiest organisms suggest where we might find life beyond Earth.
