Astronomy Education Are We Alone - where science isn't alien.
“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.”
Dominic Riley – bookbinder in the U.K.

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?

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

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.

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.

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.

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.

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?

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?”
Guests:
Benjamin Radford - Research fellow with the Committee for Skeptical Inquiry
Nadia Drake - Science journalist and member of NASA’s UAP group

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?
Guests:
David Peterson - Meteorologist, U.S. Naval Research Laboratory
Stephen Pyne - Emeritus professor at Arizona State University, fire historian, urban farmer, author of “The Pyrocene: How We Created an Age of Fire, and What Happens Next”

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
Tim Jarvis – Adventurer and environmental scientist

Is your windshield accumulating less bug splatter? Insects, the most numerous animals on Earth, are becoming scarcer, and that’s not good news. They’re essential, and not just for their service as pollinators. We ask what’s causing the decrease in insect populations, and how can it be reversed.
Also, the story of how California’s early citrus crops came under attack – a problem that was solved by turning Nature on itself. And how chimpanzee “doctors” use insects to treat wounds.
We investigate the small and the many on “The Latest Buzz.”

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.

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.

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?
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

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.

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?
Guest:

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.

Are you ready to defer all your personal decision-making to machines? Polls show that most Americans are uneasy about the unchecked growth of artificial intelligence. The possible misuse of genetic engineering also makes us anxious. We all have a stake in the responsible development of science and technology, but fortunately, science fiction films can help.
The movies Ex Machina and Jurassic Park suggest where A.I. and unfettered gene-tinkering could lead. But even less popular sci-fi movies can help us imagine unsettling scenarios regarding over-population, smart drugs, and human cloning.
And not all tales are grim. The 1951 film, The Man in the White Suit, weaves a humorous story of materials science run amok.
So, grab a bowl of popcorn and join us in contemplating the future of humanity as Hollywood sees it!

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.

Heredity was once thought to be straightforward. Genes were passed in an immutable path from parents to you, and you were stuck – or blessed – with what you got. DNA didn’t change.
But now we know that’s not true. Epigenetic factors, such as your environment and your lifestyle, control how your genes are expressed. Meanwhile, the powerful tool CRISPR allows us to tinker with the genes themselves. DNA is no longer destiny.
Hear the results from the NASA twin study and what happened to astronaut Scott Kelly’s DNA after a year on the International Space Station. Plus, whether there’s evidence that epigenetic changes can be passed down. And, if we can wipe out deadly malaria by engineering the mosquito genome for sterility, should we do it?

Birds have it going on. Many of these winged dinosaurs delight us with their song and brilliant plumage. Migratory birds travel thousands of miles in a display of endurance that would make an Olympic athlete gasp.
We inquire about these daunting migrations and how birds can fly for days without rest. And what can we do to save disappearing species? Will digital tracking technology help? Plus, how 19th century bird-lovers, appalled by feathered hats, started the modern conservation movement.
Guests:
Scott Weidensaul – Ornithologist and naturalist and author of “A World on the Wing: the Global Odyssey of Migratory Birds.”
Kassandra Ford – Doctoral candidate in evolutionary biology at the University of Louisiana at Lafayette.

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.

Back off, you Neanderthal! It sounds as if you’ve just been dissed, but maybe you should take it as a compliment. Contrary to common cliches, our Pleistocene relatives were clever, curious, and technologically inventive. Find out how our assessment of Neanderthals has undergone a radical rethinking, and hear about the influence they have as they live on in our DNA. For example, some of their genes have a strong association with severe Covid 19 infection. Plus, how Neanderthal mini-brains grown in a lab will teach us about the evolution of Homo sapiens.

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?

Dr. Oz’s personable and folky approach when talking about difficult health subjects has made him a trusted source for medical information. But some of the claims offered on The Doctor Oz Show are clearly questionable, such as the existence of miracle diet pills. Now the show is on hiatus so that “America’s Doctor” can run for the U.S. Senate.
In our regular look at critical thinking, Skeptic Check, we evaluate Mehmet Oz’s record on presenting evidence-based health and medical information in light of his running for Congress, where he would be empowered to influence health policy.

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”

Solid materials get all the production credit. Don’t get us wrong, we depend on their strength and firmness for bridges, bones, and bento boxes. But liquids do us a solid, too. Their free-flowing properties drive the Earth’s magnetic field, inspire a new generation of smart electronics, and make biology possible. But the weird thing is, they elude clear definition. Is tar a liquid or a solid? What about peanut butter?
In this episode: A romp through a cascade of liquids with a materials scientist who is both admiring and confounded by their properties; how Earth’s molten iron core is making the magnetic north pole high-tail it to Siberia; blood as your body’s information superhighway; and how a spittlebug can convert 200 times its body weight in urine into a cozy, bubble fortress.

Is your windshield accumulating less bug splatter? Insects, the most numerous animals on Earth, are becoming scarcer, and that’s not good news. They’re essential, and not just for their service as pollinators. We ask what’s causing the decrease in insect populations, and how can it be reversed.
Also, the story of how California’s early citrus crops came under attack – a problem that was solved by turning Nature on itself. And how chimpanzee “doctors” use insects to treat wounds.
We investigate the small and the many on “The Latest Buzz.”

The nuclear threat is back, and the Doomsday Clock is almost at midnight. How did we end up here again? In the 1930s, German physicists learned that splitting the nuclei of heavy atoms could release tremendous amounts of energy. Such theoretical ideas became relevant when WW II began.
Today, we try to eliminate nuclear weaponry while exploiting the atom for peaceful uses, such as energy generation. But as the invasion of Ukraine shows, power plants can also be military targets. We lay out some of the questions that scientists and strategists are grappling with considering recent events.

DNA is the gold standard of identification. Except when it’s not. In rare cases when a person has two complete sets of DNA, that person’s identity may be up in the air. Meanwhile, DNA ancestry tests are proving frustratingly vague: dishing up generalities about where you came from rather than anything specific. And decoding a genome is still relatively expensive and time-consuming. So, while we refine our ability to work with DNA, the search is on for a quick and easy biomarker test to tell us who we are.
In this hour: the story of chimeras – people who have two sets of DNA; a reporter whose ancestry tests revealed she is related to Napoleon and Marie Antoinette; and the eyes have it in Somaliland, the first nation to use iris scans in an election. Find out why your irises may be what ultimately distinguishes you from the crowd.

There’s no place like “ome.” Your microbiome is highly influential in determining your health. But it’s not the only “ome” doing so. Your exposome – environmental exposure over a lifetime – also plays a role.
Hear how scientists hope to calculate your entire exposome, from food to air pollution to water contamination.
Plus, new research on the role that microbes play in the development of neurological diseases such as Parkinson’s, and the hot debate about when microbes first colonize the body. Could a fetus have its own microbiome?
Also, choose your friends wisely: studies of microbe-swapping gazelles reveal the benefits – and the downsides – of being social.
And, why sensors on future toilets will let you do microbiome analysis with every flush.

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.

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.

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.

Scientists are increasingly finding their expertise questioned by non-experts who claim they’ve done their own “research.” Whether advocating Ivermectin to treat Covid, insisting that climate change is a hoax, or asserting that the Earth is flat, doubters are now dismissed by being told to “do your own research!” But is a Wiki page evidence? What about a YouTube video? What happens to our quest for truth along the way? Plus, a science historian goes to a Flat Earth convention to talk reason.

Beneath our feet is a living network just as complex and extensive as the root systems in a forest. Fungi, which evolved in the oceans, were among the first to colonize the barren continents more than a half-billion years ago. They paved the way for land plants, animals, and (eventually) you.
Think beyond penicillin and pizza, and take a moment to consider these amazing organisms. Able to survive every major extinction, essential as Nature’s decomposers, and the basis of both ale and antibiotics, fungi are essential to life. And their behavior is so complex you’ll be wondering if we shouldn’t call them intelligent!

The Pentagon’s report on UAPs (Unidentified Aerial Phenomena) said nothing about the possibility that some might be alien spacecraft. Nonetheless, the report has generated heightened interest in figuring out what these UAPs are, and that interest extends to some scientists. We talk to two researchers who want an open and strictly scientific investigation of these phenomena. What should they do and what do they expect to find? And finally, will the possibility of alien visitors ever be resolved?

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.

Life nearby? We’ve not yet found any on our favorite planet, Mars. But even if Mars is sterile, could we ever change that by terraforming it? Or seeding it with life from Earth?
The Red Planet is not the only game in town: A new NASA mission to a Jovian moon may give clues to biology on a world where, unlike Mars, liquid water still exists.
Also, the promise of the James Webb Space Telescope and why the solar system’s largest active volcano offers clues to the habitability of other worlds.

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.
Guests:
Suzanne Simard – Professor of Forest Ecology at the University of British Columbia and author of “Finding the Mother Tree: Discovering the Wisdom of the Forest.”

Does geoengineering offer a Plan B if nations at the U.N. climate meeting can't reduce carbon emissions? The Glasgow meeting has been called “the last best chance” to take measures to slow down global heating. But we're nowhere near to achieving the emission reductions necessary to stave off a hothouse planet. We consider both the promise and the perils of geoengineering, and ask who decides about experimenting with Earth’s climate.
Guests:
· Elizabeth Kolbert – Staff Writer at The New Yorker, Pulitzer Prize-winning author of “The Sixth Extinction,” and, most recently, of “Under a White Sky: The Nature of the Future.”

Looking to boost your brainpower? Luckily, there are products promising to help. Smart drugs, neurofeedback exercises, and brain-training video games all promise to improve your gray matter’s performance. But it’s uncertain whether these products really work. Regulatory agencies have come down hard on some popular brain training companies for false advertising. But other brain games have shown benefits in clinical trials. And could we skip the brain workout altogether and pop a genius pill instead?
In our regular look at critical thinking, we separate the pseudo from the science of commercial cognitive enhancement techniques.

400 years ago, some ideas about the cosmos were too scandalous to mention. When the Dominican friar Giordano Bruno suggested that planets existed outside our Solar System, the Catholic Inquisition had him arrested, jailed, and burned at the stake for heresy.
Today, we have evidence of thousands of planets orbiting other stars. Our discovery of extrasolar planets has dramatically changed ideas about the possibility for life elsewhere in the universe.
Modern theories about the existence of the ghostly particles called neutrinos or of collapsed stars with unfathomable gravity (black holes), while similarly incendiary, didn’t prompt arrest, of course. Neutrinos and black holes were arresting ideas because they came decades before we had the means to prove their existence.
Hear about scientific ideas that came before their time and why extrasolar planets, neutrinos, and black holes are now found on the frontiers of astronomical research.

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

Climate change isn’t happening. Vaccines make you sick. When it comes to threats to public or environmental health, a surprisingly large fraction of the population still denies the consensus of scientific evidence. But it’s not the first time – many people long resisted the evidentiary link between HIV and AIDS and smoking with lung cancer.
There’s a sense that science denialism is on the rise. It prompted a gathering of scientists and historians in New York City to discuss the problem, which included a debate on the usefulness of the word “denial” itself. Big Picture Science was there. We report from the Science Denial symposium held jointly by the New York Academy of Sciences and Rutgers Global Health Institute.
Find out why so many people dig in their heels and distrust scientific findings. Plus, the techniques wielded by special interest groups to dispute some inconvenient truths. We also hear how simply stating more facts may be the wrong approach to combating scientific resistance.

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.

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.

Without sand, engineering would be stuck in the Middle Ages. Wooden houses would line mud-packed streets, and Silicon Valley would be, well, just a valley. Sand is the building material of modern cities, and we use more of this resource than any other except water and air. Now we’re running out of it.
Hear why the Roman recipe for making concrete was lost until the 19th century, and about the super-secret mine in North Carolina that makes your smartphone possible.
Plus, engineered sand turns stormwater into drinking water, and why you might think twice about running barefoot on some tropical beaches once you learn about their biological source.
And, a special report from the coast of Louisiana where livelihoods and ecosystems depend on the successful release of Mississippi sand from levees into sediment-starved wetlands.

SMS isn’t the original instant messaging system. Plants can send chemical warnings through their leaves in a fraction of a second. And while we love being in the messaging loop – frenetically refreshing our browsers – we miss out on important conversations that no Twitter feed or inbox can capture. That’s because eavesdropping on the communications of non-human species requires the ability to decode their non-written signals.
Dive into Arctic waters where scientists make first-ever recordings of the socializing clicks and squeals of narwhals, and find out how climate shifts may pollute their acoustic landscape. Also, why the chemical defense system of plants has prompted one biologist to give greenery an “11 on the scale of awesomeness.” And, you can’t see them, but they sure can sense one another: how communicating microbes plan their attack.

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.

The seas are rising. It’s no longer a rarity to see kayakers paddling through downtown Miami. By century’s end, the oceans could be anywhere from 2 to 6 feet higher, threatening millions of people and property. But humans once knew how to adapt to rising waters. As high water threatens to drown our cities, can we learn do it again.
Hear stories of threatened land: submerged Florida suburbs, the original sunken city (Venice), and the U.S. East Coast, where anthropologists rush to catalogue thousands of low-lying historical and cultural sites in harm’s way, including Jamestown, Virginia and ancient Native American sites.
But also, stories of ancient adaptability: from the First American tribes of the Colusa in South Florida to the ice age inhabitants of Doggerland. And, modern approaches to staying dry: stilt houses, seawalls, and floating cities.

The scientific method is tried and true. It has led us to a reliable understanding of things from basic physics to biomedicine. So yes, we can rely on the scientific method. The fallible humans behind the research, not so much. And politicians? Don’t get us started. Remember when one brought a snowball to the Senate floor to “prove” that global warming was a hoax? Oy vey.
We talk to authors about new books that seem to cast a skeptical eye on the scientific method… but that are really throwing shade on the ambitious labcoat-draped humans who heat the beakers and publish the papers … as well as the pinstriped politicians who twist science to win votes.
Find out why the hyper-competitive pursuit of results that are “amazing” and “incredible” is undermining medical science… how a scientific breakthrough can turn into a societal scourge (heroin as miracle cure)… and what happens when civil servants play the role of citizen scientists on CSPAN.

Two heads may be better than one. But what about three or more? A new study shows that chimpanzees excel at complex tasks when they work in groups, and their accumulated knowledge can even be passed from one generation to the next.
But group-think also can be maladaptive. When humans rely on knowledge that they assume other people possess, they can become less than rational.
Find out why one cognitive scientist says that individual thinking is a myth. Most of your decisions are made in groups, and most derive from emotion, not rationality.
Also, why we know far less than we think we do. For example, most people will say they understand how an everyday object like a zipper works, but draw a blank when asked to explain it.

Can self-deception be useful? During the pandemic, it has been fashionable to say that we’re “following the science,” and that our behavior is determined by verifiable facts. We are, after all, self-declared rational beings, and that’s clearly useful in guiding our reaction to a pandemic. It’s true that fear and suspicion have caused some to make contrary choices such as declining vaccines, but that behavior is considered irrational. But are there situations when delusional thinking can help you thrive? Why are we not as rational as we think?

Back off, you Neanderthal! It sounds as if you’ve just been dissed, but maybe you should take it as a compliment. Contrary to common cliches, our Pleistocene relatives were clever, curious, and technologically inventive. Find out how our assessment of Neanderthals has undergone a radical rethinking, and hear about the influence they have as they live on in our DNA. For example, some of their genes have a strong association with severe Covid 19 infection. Plus, how Neanderthal mini-brains grown in a lab will teach us about the evolution of Homo sapiens.

They were pioneers in their fields, yet their names are scarcely known – because they didn’t have a Y chromosome. We examine the accomplishments of two women who pioneered code breaking and astronomy during the early years of the twentieth century and did so in the face of social opprobrium and a frequently hostile work environment.
Henrietta Leavitt measured the brightnesses of thousands of stars and discovered a way to gauge the distances to galaxies, a development that soon led to the concept of the Big Bang.
Elizabeth Friedman, originally hired to test whether William Shakespeare really wrote his plays, was soon establishing the science of code breaking, essential to success in the two world wars.
Also, the tech industry is overwhelmingly male. Girls Who Code is an initiative to redress the balance by introducing girls to computer programming, and encouraging them to follow careers in tech.

Okay you animals, line up: stoned sloths, playful pandas, baleful bovines, and vile vultures. We’ve got you guys pegged, thanks to central casting.
Or do we? Our often simplistic view of animals ignores their remarkable adaptive abilities. Stumbly sloths are in fact remarkably agile and a vulture’s tricks for thermoregulation can’t be found in an outdoors store.
Our ignorance about some animals can even lead to their suffering and to seemingly intractable problems. The South American nutria was brought to Louisiana to supply the fur market. But the species got loose and tens of millions of these rodents are destroying the environment. It literally has a bounty on its tail.
Hear about research that corrects a menagerie of misunderstandings about our fellow furry, feathered, and scaly animals, and how getting over ourselves to know them better can have practical benefits. Will you still recoil from termites if you learn that they are relevant to the future of robots, global warming, and smart design?

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?

The record of the rocks is not just the history of Earth; it’s your history too. Geologists can learn about events going back billions of years that influenced – and even made possible – our present-day existence and shaped our society.
If the last Ice Age had been a bit warmer, the rivers and lakes of the Midwest would have been much farther north and the U.S. might still be a small country of 13 states. If some Mediterranean islands hadn’t twisted a bit, no roads would have led to Rome.
Geology is big history, and the story is on-going. Human activity is changing the planet too, and has introduced its own geologic era, the Anthropocene. Will Earthlings of a hundred million years from now dig up our plastic refuse and study it the way we study dinosaur bones?

Water is essential for life – that we know. But the honeycomb lattice that forms when you chill it to zero degrees Celsius is also inexorably intertwined with life.
Ice is more than a repository for water that would otherwise raise sea levels. It’s part of Earth’s cooling system, a barrier preventing decaying organic matter from releasing methane gas, and a vault entombing ancient bacteria and other microbes.
From the Arctic to the Antarctic, global ice is disappearing. Find out what’s at stake as atmospheric CO2 threatens frozen H2O.

Inhale. Now exhale. Notice anything different? Our response to the virus is changing the air in unexpected ways. A pandemic-driven pause on travel has produced clear skies and a world-wide air quality experiment. And a new study reveals that hundreds of tons of microplastics are raining down on us each day.
But we can improve the quality of the breaths we do take; engineers have devised a high-tech mask that may kill coronavirus on contact. Plus, although you do it 25,000 times a day, you may not be breathing properly. Nose-breathing vs mouth breathing: getting the ins-and-outs of respiration.

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.

Contagion aside, coronavirus is a powerful little virus. It has prompted a global experiment in behavior modification: elbow bumps instead of handshakes, hand sanitizer and mask shortages, a gyrating stock market.
Pragmatism motivates our behavior toward the spread of this virus, but so do fear and panic. In 1918, amplified fear made the Spanish Flu pandemic more deadly.

They were pioneers in their fields, yet their names are scarcely known – because they didn’t have a Y chromosome. We examine the accomplishments of two women who pioneered code breaking and astronomy during the early years of the twentieth century and did so in the face of social opprobrium and a frequently hostile work environment.
Henrietta Leavitt measured the brightnesses of thousands of stars and discovered a way to gauge the distances to galaxies, a development that soon led to the concept of the Big Bang.
Elizabeth Friedman, originally hired to test whether William Shakespeare really wrote his plays, was soon establishing the science of code breaking, essential to success in the two world wars.

Climate change isn’t happening. Vaccines make you sick. When it comes to threats to public or environmental health, a surprisingly large fraction of the population still denies the consensus of scientific evidence. But it’s not the first time – many people long resisted the evidentiary link between HIV and AIDS and smoking with lung cancer.
There’s a sense that science denialism is on the rise. It prompted a gathering of scientists and historians in New York City to discuss the problem, which included a debate on the usefulness of the word “denial” itself. Big Picture Science was there. We report from the Science Denial symposium held jointly by the New York Academy of Sciences and Rutgers Global Health Institute.

(repeat) Fir tree needles embedded in carpet are a holiday headache. Why not decorate a genetically-modified, needle-retaining tree instead? It’s just another way that science is relevant to the holidays. We have more.
How about science experiments on fruitcake? There’s a competition that includes launching it with a pneumatic device, running a heavy electric current though it, or blasting it with a blowtorch. Meanwhile, physics provides insight into those tricky how-does-he-do-it questions about Santa’s delivery rounds.
Finally, step away from the relatives and consider the implications of the winter solstice.
Enjoy a better holiday through science!

(repeat) 400 years ago, some ideas about the cosmos were too scandalous to mention. When the Dominican friar Giordano Bruno suggested that planets existed outside our Solar System, the Catholic Inquisition had him arrested, jailed, and burned at the stake for heresy.
Today, we have evidence of thousands of planets orbiting other stars. Our discovery of extrasolar planets has dramatically changed ideas about the possibility for life elsewhere in the universe.
Modern theories about the existence of the ghostly particles called neutrinos or of collapsed stars with unfathomable gravity (black holes), while similarly incendiary, didn’t prompt arrest, of course. Neutrinos and black holes were arresting ideas because they came decades before we had the means to prove their existence.
Hear about scientific ideas that came before their time and why extrasolar planets, neutrinos, and black holes are now found on the frontiers of astronomical research.

(repeat) Two heads may be better than one. But what about three or more? A new study shows that chimpanzees excel at complex tasks when they work in groups, and their accumulated knowledge can even be passed from one generation to the next.
But group-think also can be maladaptive. When humans rely on knowledge that they assume other people possess, they can become less than rational.
Find out why one cognitive scientist says that individual thinking is a myth. Most of your decisions are made in groups, and most derive from emotion, not rationality.
Also, why we know far less than we think we do. For example, most people will say they understand how an everyday object like a zipper works, but draw a blank when asked to explain it.

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?

The possible misuse of genetic engineering also makes us anxious. We all have a stake in the responsible development of science and technology, but fortunately, science fiction films can help.
The movies Ex Machina and Jurassic Park suggest where A.I. and unfettered gene-tinkering could lead. But even less popular sci-fi movies can help us imagine unsettling scenarios regarding over-population, smart drugs, and human cloning.

Flat Earthers believe that our planet resembles – not a slightly squashed grapefruit – but a thick pancake. A journalist who covered a Flat Earth convention describes the rationale behind this ever-more popular belief.
So how do you establish science truth? We look at the difference between a truly scientific examination of extraordinary claims and approaches that feel and look science-y but aren’t.
Find out how one man will use telescopes and balloons in the desert to demonstrate that the Earth is a globe, while a biologist runs a test on the waters of Loch Ness to see if it contains prehistoric reptile DNA.

The catastrophic explosion at the Chernobyl nuclear power plant in April 1986 triggered the full-scale destruction of the reactor. But now researchers with access to once-classified Soviet documents are challenging the official version of what happened both before and after the explosion. They say that the accident was worse than we thought and that a number of factors – from paranoia to poor engineering – made the mishap inevitable. Others claim a much larger death toll from extended exposure to low levels of radiation. But with nuclear energy being a possibly essential component of dealing with rising carbon dioxide emissions, how do we evaluate risk under the long shadow of Chernobyl?

(repeat) DNA is the gold standard of identification. Except when it’s not. In rare cases when a person has two complete sets of DNA, that person’s identity may be up in the air. Meanwhile, DNA ancestry tests are proving frustratingly vague: dishing up generalities about where you came from rather than anything specific. And decoding a genome is still relatively expensive and time-consuming. So, while we refine our ability to work with DNA, the search is on for a quick and easy biomarker test to tell us who we are.
In this hour: the story of chimeras – people who have two sets of DNA; a reporter whose ancestry tests revealed she is related to Napoleon and Marie Antoinette; and the eyes have it in Somaliland, the first nation to use iris scans in an election. Find out why your irises may be what ultimately distinguishes you from the crowd.

(repeat) Dinosaurs are once again stomping and snorting their way across the screen of your local movie theater. But these beefy beasts stole the show long before CGI brought them back in the Jurassic Park blockbusters. Dinosaurs had global dominance for the better part of 165 million years. Compare that with a measly 56 million years of primate activity. We bow to our evolutionary overlords in this episode.
Our conversation about these thunderous lizards roams freely as we talk with the paleontologist who discovered Dreadnoughtus – the largest land lizard unearthed to date. Kenneth Lacovara asks that we please stop using the term “dinosaur” to refer to something outmoded, when in fact the dinos were among the most well-adapted, long-lived creatures ever.
Plus, intriguing dino facts: if you like eating chicken, you like eating dinosaurs, and how T-Rex’s puny arms helped him survive.
Also, with dozens of new species unearthed every year – nearly one a week – why we’ve entered the golden age of dinosaur discovery.

They were pioneers in their fields, yet their names are scarcely known – because they didn’t have a Y chromosome. We examine the accomplishments of two women who pioneered code breaking and astronomy during the early years of the twentieth century and did so in the face of social opprobrium and a frequently hostile work environment.
Henrietta Leavitt measured the brightnesses of thousands of stars and discovered a way to gauge the distances to galaxies, a development that soon led to the concept of the Big Bang.
Elizabeth Friedman, originally hired to test whether William Shakespeare really wrote his plays, was soon establishing the science of code breaking, essential to success in the two world wars.

Climate change isn’t happening. Vaccines make you sick. When it comes to threats to public or environmental health, a surprisingly large fraction of the population still denies the consensus of scientific evidence. But it’s not the first time – many people long resisted the evidentiary link between HIV and AIDS and smoking with lung cancer.
There’s a sense that science denialism is on the rise. It prompted a gathering of scientists and historians in New York City to discuss the problem, which included a debate on the usefulness of the word “denial” itself. Big Picture Science was there. We report from the Science Denial symposium held jointly by the New York Academy of Sciences and Rutgers Global Health Institute.

ENCORE It’s one of the most bizarre biological experiments ever. In the 18th century, a scientist fitted a pair of tailor-made briefs on a male frog to determine the animal’s contribution to reproduction. The process of gestation was a mystery and scientists had some odd-ball theories.
Today, a 5th grader can tell you how babies are made, but we still don’t know exactly what life is. In our quest to understand, we’re still at the frogs’ pants stage.
Find out why conception took centuries to figure out. Also, why the 1970s Viking experiments, specifically designed to detect life on Mars, couldn’t give us a definitive answer. Plus, can knowing where life isn’t help define what it is? Take a tour of the world’s barren places.

ENCORE Get ready for compassionate computers that feel your pain, share your joy, and generally get where you’re coming from. Computers that can tell by your voice whether you’re pumped up or feeling down, or sense changes in heart rate, skin, or muscle tension to determine your mood. Empathetic electronics that you can relate to.
But wait a minute – we don’t always relate to other humans. Our behavior can be impulsive and even self-sabotaging – our emotions are often conflicted and irrational. We cry when we’re happy. Frown when we’re pensive. A suite of factors, much of them out of our control, govern how we behave, from genes to hormones to childhood experience.
One study says that all it takes for a defendant to receive a harsher sentence is a reduction in the presiding judge’s blood sugar.
So grab a cookie, and find out how the heck we can build computers that understand us anyway.

Pluto, we hardly knew ye. Well, not anymore! Until recently, Pluto and Mars were respectively the least-known and best-known planet-sized bodies in our Solar System. Thanks to the New Horizons spacecraft, our picture of Pluto has changed from a featureless dot to a place where we can name the geologic features. And with rovers and orbiters surveying the red planet, we now know much more about Mars than our parents ever did. Examining our planetary backyard has provided insight into the trillion other planets in our galaxy.
Dive into a mountain lake and trek though the driest desert on Earth with a scientist who’s had not one but two near-fatal incidents in these extreme environments. Find out what questions compel her to keep returning.

ENCORE Time passes like an arrow, but what if it flew like a boomerang? Scientists are learning how to reverse time’s most relentless march: aging. But before we rewind time, let’s try to define it, because there’s plenty of debate about just what time is – a fundamental component of the universe or a construct of our consciousness?
Find out why, even though pondering the future may cause heartburn, mental time travel has an evolutionary survival advantage.
Plus, your brain as a clock; why “brain age” may be more accurate than chronological age in determining lifespan.
And while a million-dollar monetary prize hopes to inspire researchers to crack the aging code, one group claims they already have. By reprogramming special genes, they’ve reversed the biological clocks in mice. Find out when human trials begin.

ENCORE Einstein thought that quantum mechanics might be the end of physics, and most scientists felt sure it would never be useful. Today, everything from cell phones to LED lighting is completely dependent on the weird behavior described by quantum mechanics.
But the story continues. Quantum computers may be millions of times faster than your laptop, and applying them to big data could be transformational for biology and health. Quantum entanglement – “spooky” action at a distance – may not allow faster-than-light communication, but could be important in other ways. And there’s even the suggestion that quantum mechanics defines the difference between life and death.
Quantum physics. It’s weird and exotic. But it’s how the universe works.

It was a shocker of a story, splashed across the New York Times front page: The existence of a five-year long, hidden Pentagon investigation of UFOs. With one-third of the American public convinced that aliens are visiting Earth, could this study finally provide the proof?
We consider how this story came to light and what the $22 million program has produced. Does the existence of a secret study mean there’s now decent proof of extraterrestrial craft in our skies? We take a look at the evidence made public so far.
And why, six years after the study ended, are we learning about it now?

ENCORE For a half-century, space has been the playground of large, government agencies. While everyone could dream of becoming an astronaut, few could actually do so.
Things have changed. We hear how a geeky son of immigrant parents incentivized the ground-breaking launch of SpaceShipOne, and spawned the commercial rocket industry.
And while you’re waiting for a ticket to ride, why not build your own satellite to keep tabs on the kids or just check out the back forty? A CubeSat could be your next basement project.

ENCORE The record of the rocks is not just the history of Earth; it’s your history too. Geologists can learn about events going back billions of years that influenced – and even made possible – our present-day existence and shaped our society.
If the last Ice Age had been a bit warmer, the rivers and lakes of the Midwest would have been much farther north and the U.S. might still be a small country of 13 states. If some Mediterranean islands hadn’t twisted a bit, no roads would have led to Rome.
Geology is big history, and the story is on-going. Human activity is changing the planet too, and has introduced its own geologic era, the Anthropocene. Will Earthlings of a hundred million years from now dig up our plastic refuse and study it the way we study dinosaur bones?
Plus, the dodo had the bad luck to inhabit a small island and couldn’t adapt to human predators. But guess what? It wasn’t as dumb as you think.

ENCORE You are not alone. You can’t see ‘em, but your face is a festival of face mites. They’ve evolved with us for millennia. And a new study finds that hundreds of different tiny spiders, beetles, and – our favorite - book lice make your home theirs. But before you go bonkers with the disinfectant, consider: eradicating these critters may do more harm than good. Some are such close evolutionary partners with humans that they keep us healthy and can even reveal something about our ancestry.
But then there are bed bugs. Pests without redemption. However, their newly-sequenced genome may help us end their nightly nuisances. And of course some microscopic critters are deadly. So when it comes to bugs: when do we accommodate and when do we attack?

Will your calendar entry for November 19th be your last? Some people say yes, predicting a catastrophic collision between Earth and planet Nibiru on that date and the end of the world. But it won’t happen, because this hypothesized rogue world doesn’t exist. Nibiru’s malevolent disruptions have been foretold many times, most dramatically in 2012 and three times so far in 2017. But this year NASA issued a rare public assurance that doomsday was not in the offing.
Find out why the agency decided to speak out. Meanwhile, hoaxes and alarmist stories from the 19th century demonstrate that we have a long history of being susceptible to hooey.

We all get defensive sometimes. For some animals, evolution has provided a highly effective mechanism for saying “back off!”. A puncture by a pair of venom-filled fangs gets the point across nicely.
But one animal’s poison may be another’s cure. Some dangerous critters churn out compounds that can be synthesized into life-saving drugs.
Meet the spiny, fanged, and oozing creatures who could help defend us against such illnesses as hypertension and kidney disease.
Plus, the King of Pain - a scientist who has been stung by more than 80 species of insects in his pursuit of a better understanding of venom’s biochemistry. Find out which winged stinger scored the highest on his pain index.

Birds do it, bees do it, but humans may not do it for much longer. At least not for having children. Relying on sex to reproduce could be supplanted by making babies in the lab, where parents-to-be can select genomes that will ensure ideal physical and behavioral traits.
Men hoping to be fathers should act sooner rather than later. These same advancements in biotechnology could allow women to fertilize their own eggs, making the need for male sperm obsolete.
Meanwhile, some animals already reproduce asexually. Find out how female African bees can opt to shut out male bees intent on expanding the hive.
Will engineering our offspring have a down side? Sex creates vital genetic diversity, as demonstrated by evolution of wild animals in urban areas. Find out how birds, rodents and insects use sex in the city to adapt and thrive.

The military is a dangerous calling. But technology can help out, so researchers are constantly trying to make soldiers safer. Writer Mary Roach investigates how scientists studying so-called human factors are protecting troops from such aggressive foes as heat, noise, and fatigue. She also learns how bad odors were once considered a secret weapon.
And while soldiers have long used camouflage to help them blend in, insects may be the original masters of disguise. A discovery in fossilized amber shows that a variety of bugs employed D.I.Y. camouflaging tricks 100 million years ago.
But where is the defense race headed? The top-secret branch of the Pentagon whose job is to make tomorrow happen today has some ideas. A reporter shares DARPA’s plan for augmented super-soldiers.

Once again the aliens have landed … in theaters. It’s no spoiler to say that the latest cinematic sci-fi, Arrival, involves extraterrestrials visiting Earth.
But for some folks, the film’s premise is hardly shocking. They’re convinced that the aliens have already come. But is there any proof that aliens are here now or that they landed long ago to, for example, help build the Egyptian pyramids?
Meanwhile, SETI scientists are deploying their big antennas in an effort to establish that extraterrestrials exist far beyond Earth.
Find out why – even if E.T. is out there – one scientist says making contact is a long shot, while another pioneering scientist involved in SETI remains hopeful … and could aliens be responsible for the peculiar behavior of two star systems now making the news?

We know how the stars shine, but how do you make a star? We take an all-night ride on a high-flying jet – an airborne observatory called SOFIA – to watch astronomers investigate how a star is born.
As for how the universe was born, we know about the Big Bang but modern physics suggests that similar cosmic explosions may be happening all the time, and even hint that we could – in principle – create a new universe in a laboratory. What does this mean, and how could we do it?
From stars to universes, how it all came to be.

It’s elementary, Watson. Things are in flux – from the elements in the air you breathe to party balloons. We investigate the massive, historic loss of nitrogen from the atmosphere and meet the culprits behind a modern-day helium shortage.
But it’s not all a disappearing act: be thankful that oxygen showed up in our atmosphere a few billion years ago. Meanwhile, atom smashers have recently produced some new elements. Their appearance was brief, but long enough to fill out the periodic table.
And perhaps the tastiest use of an element – one that gives Seth a chilly reception.

In space, no one can hear you scream, but, using the right instruments, scientists can pick up all types of cosmic vibrations – the sort we can turn into sound. After a decade of listening, LIGO, a billion-dollar physics experiment, has detected gravitational waves caused by the collision of massive black holes, a brief shaking of spacetime that can be translated into a short squeal.
We listen to the chirp of black holes crashing into each other and wonder: could the universe contain more than individual sounds, but have actual musical structure?
A theoretical physicist and jazz saxophonist updates the ancient philosophical concept of the Music of the Spheres to probe the most vexing questions confronting modern cosmology.

Baby, it’s cold outside… but you still might want to be there. Some people claim that chilly temperatures are good for your health, and proponents of cryotherapy suggest you have a blast – of sub-zero air – to stave off wrinkles and perhaps halt aging altogether.
Meanwhile the field of cryonics offers the ultimate benefit by suggesting that you put future plans – and your body – on ice when you die. That way you might be revived when the technology to do so is developed.
So, will a chill wind blow you some good? Possibly, as scientists are discovering that the body can endure colder temperatures than previously thought. We examine the science of extreme cold and claims of its salubrious benefits.

Also, an astronomer learns how many rejection slips it takes before becoming a published science fiction author …. what author Bruce Sterling wants to get off his chest … and what the joke about the neutron walking into a bar to ask the price of beer has in common with H.G. Wells, Ursula K. Le Guin, and Ridley Scott.
Oh, and the price of beer? Bartender: “For you, no charge.”

It was “one giant leap for mankind,” but the next step forward may require going back. Yes, back to the moon. Only this time the hardware may come from China. Or perhaps Europe. In fact, it seems that the only developed nation not going lunar is the U.S.
Find out why our pockmarked satellite is such hot real estate, and whether it has the raw materials we’d need to colonize it. A new theory of how the moon formed may tell us what’s below its dusty surface.
But – before packing your bags – you’ll want to skim Article IX of the U.N. treaty on planetary protection. We can’t go contaminating any old planetary body, can we?

In astronomy, the rule of thumb was simple: If you can’t see it with a telescope, it’s not real. Seeing is believing. Well, tell that to the astronomers who discovered dark energy, or dark matter … or, more recently, Planet 9. And yet we have evidence that all these things exist (although skepticism about the ninth – or is it tenth? – planet still lingers).
Find out how we know what we know about the latest cosmic discoveries – even if we can’t see them directly. The astronomer who found Planet 9 – and killed Pluto – offers his evidence.
And, a speculative scenario suggests that dark matter helped do away with the dinosaurs.
Plus, the winner of the 2015 Nobel Prize in Physics explains why neutrinos that are zipping through your body right now may hold clues to the origin of the universe.

Exploration: It’s exciting, it’s novel, and you can’t always count on a round-trip ticket. You can boldly go, but you might not come back. That’s no showstopper for robotic explorers, though. Spacecraft go everywhere.
While humans have traveled no farther than the moon, our mechanical proxies are climbing a mountain on Mars, visiting an ice ball far beyond Pluto, plunging through the rings of Saturn, and landing on a comet. Oh, and did we mention they’re also bringing rock and roll to the denizens of deep space, in case they wish to listen.
We consider some of the most daring explorers since the 16th century – made of metal and plastic - venturing to places where no one else could go. What have they done, what are they doing, and at what point do they declare “mission accomplished” and head for that great spacecraft graveyard in the sky?

Eat dark chocolate. Don’t drink coffee. Go gluten-free. If you ask people for diet advice, you’ll get a dozen different stories. Ideas about what’s good for us sprout up faster than alfalfa plants (which are still healthy … we think). How can you tell if the latest is fact or fad?
We’ll help you decide, and show you how to think skeptically about popular trends. One example: a study showing that gluten-free diets didn’t ease digestive problems in athletes. Also, medical researchers test whether wearable devices succeed in getting us off the couch and a nutritionist explains how things got so confusing.
Plus, why part of our confusion may be language. Find out why one cook says that no foods are “healthy,” not even kale.

Ask anyone what extraordinary powers they’d love to have, and you’re sure to hear “be able to fly.” We’ve kind of scratched that itch with airplanes. But have we gone as far as we can go, or are better flying machines in our future? And whatever happened to our collective dream of flying cars? We look at the evolution - and the future - of flight.
Animals and insects have taught us a lot about the mechanics of becoming airborne. But surprises remain. For example, bats may flit around eccentrically, but they are actually more efficient fliers than birds.
Meanwhile, new technology may change aviation when self-healing material repairs structural cracks in mid-flight. And a scientist who worked on flying cars for DARPA says he’s now working on the next best thing.

Obesity, diabetes, heart disease … maybe even Alzheimer’s. Could these modern scourges have a common denominator? Some people believe they do: sugar.
But is this accusation warranted? We talk with a journalist who has spent two decades reporting on nutrition science, and while he says there’s still not definitive proof that sugar makes us sick, he can make a strong case for it.
Also, how a half-century ago the sugar industry secretly paid Harvard scientists to shift the culprit for heart disease from their product to dietary fat. We hear how the companies borrowed from the playbook of Big Tobacco.

She’s among the most famous missing persons in history. On the eightieth anniversary of Amelia Earhart’s disappearance, mystery still shrouds her fate. What happened during the last leg of her round-the-world trek?
Theories abound. Perhaps she ran out of fuel, and plunged into the ocean … or was captured by the Japanese. A non-profit international organization, TIGHAR, suggests she was a castaway, and offers up a new analysis of bones found on a Pacific atoll during the time of the Second World War. Their researchers will return to this possible landing spot to seek more clues this summer.
We consider these theories and weigh the new evidence surrounding Earhart’s puzzling last flight. Also, why are we uncomfortable with open-ended mysteries?

Shhh. Is someone coming? Okay, we’ll make this quick. There are a lot of scary things going on in the world. Naturally you’re fearful. But sometimes fear has a sister emotion: suspicion. A nagging worry about what’s really going on. You know, the stuff they aren’t telling you. Don’t share this, but we have evidence that both our fear response and our tendency to believe conspiracy theories are evolutionarily adaptive.
A sociologist who studies fear tells us why we’re addicted to its thrill when we control the situation, and how the media exploit our fear of losing control to keep us on edge. Plus, we examine some alien “cover-ups” and discover why it’s not just the tinfoil hat crowd that falls for outrageous plots.

Archaeologists 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?

Darwinian evolution is adaptive and slow … millennia can go by before a species changes very much. But with the tools of genetic engineering we can now make radical changes in just one generation. By removing genes or inserting new ones, we can give an organism radically different traits and behaviors. We are taking evolution into our own hands.
It all began with the domestication of plants and animals, which one science writer says created civilization. Today, as humans tinker with their own genome, is it possible we will produce Homo sapiens 2.0?
Also, what happens to those species who can’t control their destiny? How climate change is forcing the biggest genetic reshuffling in recorded history.

There are few enduring truths, but one is that no one gets out of life alive. What’s less certain is what comes next. Does everything stop with death, or are we transported to another plane of existence? First-hand accounts of people who claim to have visited heaven are offered as proof of an afterlife. Now the author of one bestseller admits that his story was fabricated.
We’ll look at the genre of “heaven tourism” to see if it has anything to say about the possible existence of the hereafter, and why the idea of an afterlife seriously influences how we live our lives on Earth.

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!

The world is hot, and getting hotter. But higher temperatures aren’t the only impact our species is having on mother Earth. Urbanization, deforestation, and dumping millions of tons of plastic into the oceans … these are all ways in which humans are leaving their mark.
So are we still in the Holocene, the geological epoch that started a mere 11,000 years ago at the end of the last ice age? Some say we’ve moved on to the age of man – the Anthropocene.
It’s the dawn of an era, but can we survive this new phase in the history of our planet?

"Dear E.T. …” So far, so good. But now what? Writing is never easy, but what if your task was to craft a message to aliens living elsewhere in the universe, and your prose would represent all humankind? Got writer’s block yet?
What to say to the aliens was the focus of a recent conference in which participants shifted their attentions away from listening for extraterrestrial signals to transmitting some. In this show, we report on the “Communicating Across the Cosmos” conference held at the SETI Institute in December 2014.
Find out what scientists think we should say. Also, how archeology could help us craft messages to an unfamiliar culture. Plus, why journalists might be well-suited to writing the message. And, a response to Stephen Hawking’s warning that attempting to contact aliens is too dangerous.

It’s the most dramatic technical development of recent times: Teams of people working for decades to produce a slow-motion revolution we call computing. As these devices become increasingly powerful, we recall that a pioneer from the nineteenth century – Ada Lovelace, a mathematician and Lord Byron’s daughter – said they would never surpass human ability. Was she right?
We consider the near-term future of computing as the Internet of Things is poised to link everything together, and biologists adopt the techniques of information science to program living cells.
Plus: What’s your favorite sci-fi computer?

You think your life is fast-paced, but have you ever seen a bacterium swim across your countertop? You’d be surprised how fast they can move.
Find out why modeling the swirl of hurricanes takes a roomful of mathematicians and supercomputers, and how galaxies can move away from us faster than the speed of light.
Also, what happens when we try to stop the dance of atoms, cooling things down to the rock bottom temperature known as absolute zero.
And why your watch doesn’t keep the same time when you’re in a jet as when you’re at the airport. It’s all due to the fact that motion is relative, says Al Einstein.

In the century and a half since Charles Darwin wrote his seminal On the Origin of the Species, our understanding of evolution has changed quite a bit. For one, we have not only identified the inheritance molecule DNA, but have determined its sequence in many animals and plants.
Evolution has evolved, and we take a look at some of the recent developments.
A biologist describes the escalating horn-to-horn and tusk-to-tusk arms race between animals, and a paleoanthropologist explains why the lineage from chimp to human is no longer thought to be a straight line but, instead, a bush. Also, New York Times science writer Carl Zimmer on the diversity of bacteria living on you, and which evolutionary concepts he finds the trickiest to explain to the public.

We all have at least some musical talent. But very few of us can play the piano like Vladimir Horowitz. His talent was rarefied, and at the tail end of the bell curve of musical ability – that tiny sliver of the distribution where you find the true outliers. Outliers also exist with natural events: hurricane Katrina, for example, or the asteroid that wiped out the dinosaurs. Such events are rare, but they often have outsized effects.
In this hour we imagine the unimaginable – including the unexpected events labeled “black swans” – and how we weigh the risk for any of them. Also, how a supervolcano explosion at Yellowstone National Park could obliterate the western U.S. but shouldn’t stop you from putting the park on your vacation itinerary.

A single ant isn’t very brainy. But a group of ants can do remarkable things. Biological swarm behavior is one model for the next generation of tiny robots. Of course, biology can get hijacked: a fungus can seize control of an ant’s brain, for example. So will humans always remain the boss of super-smart, swarming machines?
We discuss the biology of zombie ants and how to build robots that self-assemble and work together. Also, how to guarantee the moral behavior of future ‘bots.
And, do you crave cupcakes? Research suggests that gut bacteria control what we eat and how we feel.

Hang on to your globe. One day it’ll be a collector’s item. The arrangement of continents you see today is not what it once was, nor what it will be tomorrow. Thank plate tectonics.
Now evidence suggests that the crowding together of all major land masses into one supercontinent – Pangaea, as it’s called – is a phenomenon that’s happened over and over during Earth’s history. And it will happen again. Meet our future supercontinent home, Amasia, and learn what it will look like.
Meanwhile, as California waits for the Big One, geologists discover that major earthquakes come in clusters. Also, our planet is not the only solar system body with tectonic activity. Icy Europa is a mover and shaker too.

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.

If you move with the times, you might stick around long enough to pass on your genes. And that is adaptation and evolution, in a nutshell.
But humans are changing their environment faster than their genes can keep pace. This has led to a slew of diseases – from backache to diabetes – according to one evolutionary biologist. And our technology may not get us out of the climate mess we’ve created. So just how good are we at adapting to the world around us?

Sure you have a big brain; it’s the hallmark of Homo sapiens. But that doesn’t mean that you’ve cornered the market on intelligence. Admittedly, it’s difficult to say, since the very definition of the term is elusive. Depending on what we mean by intelligence, a certain aquatic mammal is not as smart as we thought (hint: rhymes with “caulpin”) … and your rhododendron may be a photosynthesizing Einstein.

We may be connected, but some say we’re not communicating. The consequences could be dire. A U.S. Army major says that social media are breaking up our “band of brothers,” and that soldiers who tweet rather than talk have less cohesion in combat.
What’s the solution? Maybe more connectivity to jump start conversation? The makers of Hello Barbie say its sophisticated speech recognition system will engage children in conversation. But an alternative strategy is to go cold turkey: sign up for a device-free camp (for adults) or stuff a NoPhone in your pocket, and wean yourself from the real thing.
But MIT’s Sherry Turkle says there’s only one solution: more face-to-face time. Without it, we are in danger of losing our empathy.

Do you feel happy today? How about happily disgusted? Maybe sadly surprised, or sadly disgusted? Human emotions are complex. But at least they’re the common language that unites us all – except when they don’t. A tribe in Namibia might interpret our expression of fear as one of wonderment. And people with autism don’t feel the emotions that others do.
So if you’re now delightfully but curiously perplexed, tune in and discover the evolutionary reason for laughter … how a computer can diagnose emotional disorders that doctors miss … and why the world’s most famous autistic animal behaviorist has insight into the emotional needs of cattle.

What’s for dinner? Meat, acorns, tubers, and fruit. Followers of the Paleo diet say we should eat what our ancestors ate 10,000 years ago, when our genes were perfectly in synch with the environment.
We investigate the reasoning behind going paleo with the movement’s pioneer, as well as with an evolutionary biologist. Is it true that our genes haven’t changed much since our hunter-gatherer days?
Plus, a surprising dental discovery is nothing for cavemen to smile about.

One day, coffee is good for you; the next, it’s not. And it seems that everything you eat is linked to cancer, according to research. But scientific studies are not always accurate. Insufficient data, biased measurements, or a faulty analysis can trip them up. And that’s why scientists are always skeptical.
Hear one academic say that more than half of all published results are wrong, but that science still remains the best tool we have for learning about nature.
Also, a cosmologist points to reasons why science can never give us all the answers.

It’s hard to imagine the twists and turns of evolution that gave rise to Homo Sapiens. After all, it required geologic time, and the existence of many long-gone species that were once close relatives. That may be one reason why – according to a recent poll – one-third of all Americans reject the theory of evolution. They prefer to believe that humans and other living organisms have existed in their current form since the beginning of time.
But if you’ve ever been sick, you’ve been the victim of evolution on a very observable time scale. Nasty viruses and bacteria take full advantage of evolutionary forces to adapt to new hosts. And they can do it quickly.
Discover how comparing the deadly 1918 flu virus with variants today may help us prevent the next pandemic. Also, while antibiotic resistance is threatening to become a major health crisis, better understanding of how bacteria evolve their defenses against our drugs may help us out.

Imagine a world without algebra. We can hear the sound of school children applauding. What practical use are parametric equations and polynomials, anyway? Even some scholars argue that algebra is the Latin of today, and should be dropped from the mandatory curriculum.
But why stop there? Maybe we should do away with math classes altogether.
An astronomer says he’d be out of work: we can all forget about understanding the origins of the universe, the cycles of the moon and how to communicate with alien life. Also, no math = no cybersecurity + hackers (who have taken math) will have the upper hand.
Also, without mathematics, you’ll laugh < you do now. The Simpsons creator Matt Groening has peppered his animated show with hidden math jokes.

Monsters don’t exist. Except when they do. And extinction is forever, except when it isn’t. So, which animals are mythical and which are in hiding?
Bigfoot sightings are plentiful, but real evidence for the hirsute creature is a big zilch. Yet, the coelacanth, a predatory fish thought extinct, actually lives. Today, its genome is offering clues as to how and when our fishy ancestors first flopped onto land.
Meanwhile, the ivory-billed woodpecker assumes mythic status as it flutters between existence and extinction. And, from passenger pigeons to the wooly mammoth, hi-tech genetics may imitate Jurassic Park, and bring back vanished animals.

Imagine a world without algebra. We can hear the sound of school children applauding. What practical use are parametric equations and polynomials, anyway? Even some scholars argue that algebra is the Latin of today, and should be dropped from the mandatory curriculum.
But why stop there? Maybe we should do away with math classes altogether.
An astronomer says he’d be out of work: we can all forget about understanding the origins of the universe, the cycles of the moon and how to communicate with alien life. Also, no math = no cybersecurity + hackers (who have taken math) will have the upper hand.

Dig beneath the icy shell of Jupiter’s moon Europa, and plunge into the jets of Enceladus, Saturn’s satellite.
And let’s not forget the Red Planet. Mars is rusty and dusty, but it wasn’t always a world of dry dunes. Did life once thrive here? Also, the promise of life in the exotic hydrocarbon lakes of Titan.
Science-fiction author Robert J. Sawyer joins us, and relates how these exotic outposts have prompted imaginative stories of alien life.

You may be unique, but is your home planet? NASA’s Kepler spacecraft has uncovered thousands of planetary candidates, far far beyond our solar system. Some may be habitable and possibly even Earth-like. But now a failure in its steering apparatus may bring an abrupt end to this pioneering telescope’s search for new worlds.
But Kepler has a massive legacy of data still to be studied. Many new worlds will undoubtedly be found in these data. Hear why the astronomer who has discovered the greatest number of exoplanets is hopeful about the hunt for alien life, and meet the next generation of planet-hunting instruments.
Also, “Weird worlds? That was our idea!” Sci-fi writers lay claim to the first musings on exotic planetary locales. And a biographer of Magellan and Columbus describes the dangerous hunt for new worlds five centuries ago.

It’s a record we didn’t want to break. The carbon dioxide concentration in the atmosphere hits the 400 parts-per-million mark, a level which some scientists say is a point of no return for stopping climate change. A few days later, a leading newspaper prints an op-ed essay that claims CO2 is getting a bad rap: it’s actually good for the planet. The more the better.
Skeptic Phil Plait rebuts the CO2-is-awesome idea while a paleontologist paints a picture of what Earth was like when the notorious gas last ruled the planet. Note: humans weren’t around.
Plus, our skit says NO to O2 … and a claim that climate change skeptics have borrowed from the Creationists’ playbook in challenging the teaching of established science in schools.

“Making space for everyone” could be NASA’s motto. But as commercial spaceships get ready to blast off, that populist idea is being tested. Space cowboys in the private sector say they’re the ones who can provide unfettered access to space, for tourists and scientists alike.
Meet a scientist who already has a ticket to ride on SpaceShip Two and discover what he hopes to learn about asteroids during his five minutes of weightlessness.
Plus, NASA in motion: it’s back to the moon as the GRAIL mission probes the interior of our lovely lunar satellite. Also, can you dig it? The rover Curiosity can. It’s headed to Mars to hunt for clues to alien life … with a jackhammer.
Also, as the Hubble Space Telescope shuts down, the James Webb Space Telescope revs up. Or does it? The telescope is designed to study the birth of galaxies and hunt for evidence of water on far away worlds. But will Congress pull the plug?
Guests:
James Oberg - former Space Shuttle Mission Control engineer, and space expert

The language of science is mathematics. As incredible as it seems, the universe seems to run according to laws we can write down on chalkboards.
But it’s not just lab-coated researchers who wield the tool of math: Madison Avenue knows that if they tell you that a shampoo is 32 percent better, you’re likely to buy it.
Also, how scientists of the early twentieth century were forced to invent entirely new mathematical paradigms to describe the cosmos on big scales and small – the theories of general relativity and quantum mechanics.
Plus, what about everyday arithmetic? Have pocket calculators and digital cash registers dumbed down the populace?

And, the man who made it all possible: 400 years of Galileo and the telescope. Part of our series for the International Year of Astronomy.
