Big Picture Science for Monday 22 June 2015 - Skeptic Check: Evolutionary Arms Race

Big Picture Science - Skeptic Check: Evolutionary Arms Race

ENCORE: 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.

And the geneticist who sequenced the Neanderthal genome says yes, our hirsute neighbors co-mingled with humans.

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

Guests:

• Svante Pääbo – Evolutionary geneticist, Max Planck Institute for Evolutionary Anthropology, author of Neanderthal Man: In Search of Lost Genomes
• Ann Reid – – Molecular biologist, executive director of the National Center for Science Education, Oakland, California

Big Picture Science for Monday 15 June 2015 - It's All Relative

Big Picture Science - It's All Relative

A century ago, Albert Einstein rewrote our understanding of physics with his Theory of General Relativity. Our intuitive ideas about space, time, mass, and gravity turned out to be wrong.

Find out how this masterwork changed our understanding of how the universe works and why you can thank Einstein whenever you turn on your GPS.

Also, high-profile experiments looking for gravitational waves and for black holes will put the theories of the German genius to the test – will they pass?

And why the story of a box, a Geiger counter, and a zombie cat made Einstein and his friend Erwin Schrödinger uneasy about the quantum physics revolution.

Guests:

• Jeffrey Bennett – Astronomer, author of What Is Relativity?: An Intuitive Introduction to Einstein’s Ideas, and Why They Matter

Big Picture Science for Monday 25 May 2015 - Skeptic Check: After the Hereafter

Big Picture Science - Skeptic Check: After the Hereafter

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.

Also, a neurologist describes what is going on in the brain during near-death and other out-of-body experiences.

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

Guests:

• Ben Radford – Paranormal investigator, research fellow at the Committee for Skeptical Inquiry and deputy editor of the Skeptical Inquirer, and author of the Discovery News article, “Why People Believed Boy’s ‘Visit to Heaven’ Story”

Big Picture Science for Monday 30 March 2015 - Hidden History

Big Picture Science - Hidden History

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

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

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

Guests:

• Mark Adams – author, Meet Me in Atlantis: My Obsessive Quest to Find the Sunken City
• David Morrison – Senior scientist, NASA Ames Research Center

Big Picture Science for Monday 02 February 2015 - Digging Our Past

Big Picture Science - Digging Our Past

ENCORE: What’s past is prologue. For centuries, researchers have studied buried evidence – bones, teeth, or artifacts – to learn about murky human history, or even to investigate vanished species. But today’s hi-tech forensics allow us to analyze samples dug from the ground faster and at a far more sophisticated level.

First, the discovery of an unknown species of dinosaur that changes our understanding of the bizarre beasts that once roamed North America.

And then some history that’s more recent: two projects that use the tools of modern chemistry and anthropology to deepen our understanding of the slave trade.

Plus, an anthropologist on an evolutionary habit that is strange to some, but nonetheless common all over the world: the urge to eat dirt.

Big Picture Science for Monday 12 January 2015 - How to Talk to Aliens

Big Picture Science - How to Talk to Aliens

“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.

Big Picture Science for Monday 29 December 2014 - Skeptic Check: Got a Sweet Truth?

Big Picture Science - Skeptic Check: Got a Sweet Truth?

ENCORE: The sweet stuff is getting sour press. Some researchers say sugar is toxic. A new study seems to support that idea: mice fed the human equivalent of an extra three sodas a day become infertile or die. But should cupcakes be regulated like alcohol?

Hear both sides of the debate. Another researcher says that animal studies are misleading, and that for good health, you should count calories, not candy and carbs.

Plus, an investigative reporter exposes the tricks that giant food companies employ to keep you hooked on sugar, salt, and fat.

Also, a listener corrects our pronunciation of Neil Armstrong’s birthplace in the Sounds Abound episode.

Big Picture Science for Monday 22 December 2014 - Science Fiction True

Big Picture Science - Science Fiction True

Don’t believe everything you see on TV or the movies. Science fiction is just a guide to how our future might unfold. It can be misleading, as anyone who yearns for a flying car can tell you. And yet, sometimes fantasy becomes fact. Think of the prototype cellphones in Star Trek.

We take a look at science that seems inspired by filmic sci-fi, for example scientists manipulating memory as in Sunshine of the Spotless Mind. And despite his famous film meltdown, Charleton Heston hasn’t stopped the Soylent company from producing what it calls the food of the future.

Plus, why eco-disaster films have the science wrong, but not in the way you might think. And, what if our brains are simply wired to accept film as fact?

Guests:

• Steve Ramirez -Neuroscientist, Massachusetts Institute of Technology
• Rob Rhinehart – CEO and founder of Soylent

Big Picture Science - Shocking Ideas

Electricity is so 19^th century. Most of the uses for it were established by the 1920s. So there’s nothing innovative left to do, right? That’s not the opinion of the Nobel committee that awarded its 2014 physics prize to scientists who invented the blue LED.

Find out why this LED hue of blue was worthy of our most prestigious science prize … how some bacteria actually breathe rust … and a plan to cure disease by zapping our nervous system with electric pulses.

Big Picture Science for Monday 08 December 2014 - Living Computers

Big Picture Science - Living Computers

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?

Big Picture Science - Long Live Longevity

ENCORE: Here’s to a long life – which, on average, is longer today than it was a century ago. How much farther can we extend that ultimate finish line? Scientists are in hot pursuit of the secret to longer life.

The latest in aging studies and why there’s a silver lining for the silver-haired set: older people are happier. Also, what longevity means if you’re a tree. Plus, why civilizations need to stick around if we’re to make contact with E.T.

And, how our perception of time shifts as we age, and other tricks that clocks play on the mind.

Guests:

• Ted Anton – Professor of English, DePaul University, Chicago, author of The Longevity Seekers: Science, Business, and the Fountain of Youth

Big Picture Science for Monday 03 November 2014 - Sounds Abound

Big Picture Science - Sounds Abound

ENCORE: The world is a noisy place. But now we have a better idea what the fuss is about. Not only can we record sound, but our computers allow us to analyze it.

Bird sonograms reveal that our feathery friends give each other nicknames and share details about their emotional state. Meanwhile, hydrophones capture the sounds of dying icebergs, and let scientists separate natural sound from man-made in the briny deep.

Plus, native Ohio speakers help decipher what Neil Armstrong really said on that famous day. And, think your collection of 45 rpm records is impressive? Try feasting your ears on sound recorded before the Civil War.

Guests:

Big Picture Science for Monday 06 October 2014 - What's the Difference?

Big Picture Science - What's the Difference?

We make split second decisions about others – someone is male or female, black or white, us or them. But sometimes the degrees of separation are incredibly few. A mere handful of genes determine skin color, for example.

Find out why race is almost non-existent from a biological perspective, and how the snippet of DNA that is the Y chromosome came to separate male from female.

Plus, why we’re wired to categorize. And, a groundbreaking court case proposes to erase the dividing line between species: lawyers argue to grant personhood status to our chimpanzee cousins.

Guests:

• David Page – Biologist and geneticist, at the Whitehead Institute for Biomedical Research and the Massachusetts Institute of Technology

Big Picture Science for Monday 29 September 2014 - Land on the Run

Big Picture Science - Land on the Run

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.

And why is land in the western part of the U.S. literally rising up? Mystery solved!

Guests:

• John Dvorak – Geologist, author of Earthquake Storms: The Fascinating History and Volatile Future of the San Andreas Fault
• Adrian Borsa – Geophysicist, Scripps Institute of Oceanography, University of California, San Diego
