ENCORE There are many kinds of islands. There’s your iconic sandy speck of land topped with a palm tree, but there’s also our home planet – an island in the vast seas of space. You might think of yourself as a biological island … until you tally the number of microbes living outside – and inside – your body.
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.
ENCORE We love our family and friends, but sometimes their ideas about how the world works seem a little wacky. We asked BiPiSci listeners to share examples of what they can’t believe their loved-ones believe, no matter how much they hear rational explanations to the contrary. Then we asked some scientists about those beliefs, to get their take.
Discover whether newspaper ink causes cancer … if King Tut really did add a curse to his sarcophagus … the efficacy of examining your irises – iridology – to diagnose disease … and more!
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.
ENCORE We all want to turn back time. But until we build a time machine, we’ll have to rely on a few creative approaches to capturing things as they were – and preserving them for posterity. One is upping memory storage capacity itself. Discover just how much of the past we can cram into our future archives, and whether going digital has made it all vulnerable to erasure.
We often hear fantastic scientific claims that would change everything if true. Such as the report that algae is growing on the outside of the International Space Station or that engineers have built a rocket that requires no propellant to accelerate. We examine news stories that seem too sensational to be valid, yet just might be - including whether a killer asteroid has Earth’s name on it.
A planet is a planet is a planet. Unless it’s Pluto - then it’s a dwarf planet. But even then it’s a planet, according to experts. So what was behind the unpopular re-classification of Pluto by astronomers, and were they justified?
As the New Horizons spacecraft closes in on this small body, one planetary scientist says that this dwarf planet could be more typical of planets than Mars, Mercury, and Saturn. And that our solar system has not 8 or even 9 planets, but 900.
ENCORE Hi ho, hi ho ... it’s out with work we go! As you relax this holiday weekend, step into our labor-atory and imagine a world with no work allowed. Soft robots help us with tasks at home and at the office, while driverless cars allow us to catch ZZZZs in the front seat.
Plus, the Internet of Everything interconnects all your devices, from your toaster to your roaster to … you. So there’s no need to ever get off the couch. But is a machine-ruled world a true utopia?
And, the invention that got us into our 24/7 rat race: Edison’s electric light.
ENCORE We’ve all hit the snooze button when the alarm goes off, but why do we crave sleep in the first place? We explore the evolutionary origins of sleep … the study of narcolepsy in dogs … and could novel drugs and technologies cut down on our need for those zzzzs.
Plus, ditch your dream journal: a brain scanner may let you record – and play back – your dreams.
And, branch out with the latest development in artificial light: bioluminescent trees. How gene tinkering may make your houseplants both grow and glow.
ENCORE Maybe goodbye isn’t forever. Get ready to mingle with mammoths and gaze upon a ground sloth. Scientists want to give some animals a round-trip ticket back from oblivion. Learn how we might go from scraps of extinct DNA to creating live previously-extinct animals, and the man who claims it’s his mission to repopulate the skies with passenger pigeons.
But even if we have the tools to bring vanished animals back, should we?
Plus, the extinction of our own species: are we engineering the end of humans via our technology?
Who’s watching you? Could be anyone, really. Social media sites, webcams, CCTV cameras and smartphones have made keeping tabs on you as easy as tapping “refresh” on a tablet. And who knows what your cell phone records are telling the NSA?
Surveillance technology has privacy on the run, as we navigate between big data benefits and Big Brother intrusion.
Find out why wearing Google Glass could make everything you see the property of its creator, and which Orwellian technologies are with us today. But just how worried should we be? A cyber security expert weighs in.
ENCORE Face it – humans are pattern-seeking animals. We identify eyes, nose and mouth where there are none. Martian rock takes on a visage and the silhouette of Elvis appears in our burrito. Discover the roots of our face-tracking tendency - pareidolia - and why it sometimes leads us astray.
Plus, why some brains can't recognize faces at all … how computer programs exhibit their own pareidolia … and why it’s so difficult to replicate human vision in a machine
ENCORE Think back, way back. Beyond last week or last year … to what was happening on Earth 100,000 years ago. Or 100 million years ago. It’s hard to fathom such enormous stretches of time, yet to understand the evolution of the cosmos - and our place in it – your mind needs to grasp the deep meaning of eons. Discover techniques for thinking in units of billions of years, and how the events that unfold over such intervals have left their mark on you.
ENCORE It’s hard to get lost these days. GPS pinpoints your location to within a few feet. Discover how our need to get from A to B holds clues about what makes us human, and what we lose now that every digital map puts us at the center.
Plus, stories of animal navigation: how a cat found her way home across Florida, and the magnetic navigation systems used by salmon and sea turtles.
Also, why you’ll soon be riding in driverless cars. And, how to map our universe.
You are surrounded by products. Most of them, factory-made. Yet there was a time when building things by hand was commonplace, and if something stopped working, well, you jumped into the garage and fixed it, rather than tossing it into the circular file.
Participants at the Maker Faire are bringing back the age of tinkering, one soldering iron and circuit board at a time. Meet the 12-year old who built a robot to solve his Rubik’s Cube, and learn how to print shoes at home. Yes, “print.”
Alien life. A flurry of recent discoveries has shifted the odds of finding it. Scientists use the Kepler telescope to spot a planet the same size and temperature as Earth … and announce that there could be tens of billions of similar worlds, just in our galaxy!
Plus, new gravity data suggests a mammoth reservoir of water beneath the icy skin of Saturn’s moon Enceladus … and engineers are already in a race to design drills that can access the subsurface ocean of another moon, Jupiter's Europa.
Get ready for déjà vu as you listen to some of our favorite interviews in the past year. It's our annual fundraising podcast. Come for the great interviews, stay for the great interviews. Lend us your support along the way.
What’s for dinner? Maybe fried bugs. Listen as we do a taste test. Speaking of dinner, learn why saliva’s acceptable as long as it’s in our mouth. But dollop some into our own soup, and we push the bowl away.
What goes up must come down. But it’s human nature to want to put things back together again. It can even be a matter of survival in the wake of some natural or manmade disasters.
First, a portrait of disaster: the eruption of Tambora in 1815 is the biggest volcanic explosion in 5,000 years. It changed the course of history, although few people have heard of it.
Then, stories of reconstruction: assembling, disassembling, moving and reassembling one of the nation's largest T. Rex skeletons, and what we learn about dinos in the process.
ENCORE Imagine biting into a rich chocolate donut and not tasting it. That’s what happened to one woman when she lost her sense of smell. Discover what scientists have learned about how the brain experiences flavor, and the evolutionary intertwining of odor and taste.
Plus a chef who tricks tongues into tasting something they’re not. It’s chemical camouflage that can make crabgrass taste like basil and turn bitter crops into delicious dishes – something that could improve nutrition world-wide.
ENCORE We all crave power: to run laptops, charge cell phones, and play Angry Birds. But if generating energy is easy, storing it is not. Remember when your computer conked out during that cross-country flight? Why can’t someone build a better battery?
Discover why battery design is stuck in the 1800s, and why updating it is key to future green transportation (not to mention more juice for your smartphone). Also, how to build a new type of solar cell that can turn sunlight directly into fuel at the pump.
