Perpetual Emotion Machine [rebroadcast]

1/13/2020
More
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...

Your Brain's Reins [rebroadcast]

1/6/2020
More
You are your brain. But what happens when your brain changes for the worse – either by physical injury or experience? Are you still responsible for your actions? We hear how the case of a New York man charged with murder was one of the first to introduce neuroscience as evidence in court. Plus, how technology hooks us – a young man so addicted to video games, he lacked social skills, or even a desire to eat. Find out how technology designers conspire against his digital detox. Also, even...

Skeptic Check: Heal Thyself [rebroadcast]

12/30/2019
More
Do we still need doctors? There are umpteen alternative sources of medical advice, including endless and heartfelt health tips from people without medical degrees. Frankly, self-diagnosis with a health app is easier and cheaper than a trip to a clinic. Since we’re urged to be our own health advocate and seek second opinions, why not ask Alexa or consult with a celebrity about what ails us? Find out if you can trust these alternative medical advice platforms. Plus, lessons from an AIDS...

The stress of the holidays can make you want to hide under the covers with a warm cup of cocoa. From gift buying to family gatherings, the holidays can feel like being inside a pressure cooker. But don’t despair! Science can help make the holidays a little brighter, from some gift-giving tips from our animal friends to embracing pessimism before a challenging social event to stopping that annoying merry melody on repeat in your head. Guests: Adam SouthMitch RatcliffeJulie NoremThe Positive...

Waste Not

12/16/2019
More
Why create more landfill? Perhaps you should resist the urge to toss those old sneakers, the broken ceiling fan, or last year’s smart phone. Instead, repurpose them! Global junk entrepreneurs are leading the way in turning trash to treasure, while right-to-repair advocates fight for legislation that would give you a decent shot at fixing your own electronic devices. And, if you toss food scraps down the drain as you cook, are you contributing to a “fatberg” horror in the...

Shell on Earth

12/9/2019
More
(repeat) We all may retreat to our protective shells, but evolution has perfected the calcite variety to give some critters permanent defense against predators. So why did squids and octopuses lose their shells? Find out what these cephalopods gained by giving up the shell game. Plus why Chesapeake Bay oyster shells are shells of their former selves. What explains the absence of the dinner-plate sized oysters of 500,000 years ago, and how conservation paleobiology is probing deep time for...

Yule Like This

12/2/2019
More
(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...

Skeptic Check: Betting on Pseudoscience

11/25/2019
More
Psychics may not be able to predict the future or sense your thoughts. Nonetheless, they rake in hundreds of millions of dollars every year. But the harm from pseudoscience can go far beyond your wallet – especially when it promotes unscientific treatments for serious disease. Find out what alarming discovery led one naturopath to quit her practice and why scientific ignorance is not bliss. It’s our regular look at critical thinking, but don’t take our word for it. Guests: Robert Palmer –...

Stopping Ebola

11/18/2019
More
A new vaccine may help turn Ebola into a disease we can prevent, and a new drug may make it one we can cure. But the political crisis in the Democratic Republic of Congo has fueled violence against health workers and Ebola treatment centers. Find out why context matters in the efforts to stop Ebola, what new drugs and vaccines are on the horizon, and whether the world is prepared for the next infectious pandemic. Even if Ebola’s threat is diminishing, what about the next pandemic? Is the...

Radical Cosmology

11/11/2019
More
(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...

Supercomputer Showdown

11/4/2019
More
Do you have a hard-to-answer question? The Summit, Sierra, Trinity, Frontier, and Aurora supercomputers are built to tackle it. Summit tops the petaflop heap – at least for now. But Frontier and Aurora are catching up as they take aim at a new performance benchmark called exascale. So why do we need all this processing power? From climate modeling to personalized medicine, find out why the super-est computers are necessary to answer our biggest questions. But is the dark horse candidate,...

Skeptic Check: Rational Lampoon

10/28/2019
More
(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...

For two Swiss astronomers, it’s “Stockholm, here we come.” Their first-ever discovery of a planet orbiting another star has been awarded the most prestigious prize in science. Find out how their exoplanet discovery led to 4,000 more and how that changes the odds of finding life beyond Earth. Also, the Nobel committee is not alone in finding distant worlds inspirational: a musician is translating their orbital signatures into sound. Guests: Roy Gould - Universe in CreationJeffrey Smith -...

Go With the Flow

10/14/2019

(repeat) 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...

Battling Bacteria

10/7/2019
More
We can’t say we weren’t warned. More than 75 years ago, bacteriologist Rene Dubos cautioned that misuse of antibiotics could breed drug-resistant bacteria – and he has been proved prescient. In this episode: the rise of superbugs, why we ignored the warnings about them, how some are enlisting an old therapy to fight back, and whether we’ll heed history’s lessons in the face of a future pandemic. Plus, a weird unforeseen effect of antibiotics being investigated at the Body...

The stone heads on Easter Island are an enduring mystery: why were they built and why were they abandoned and destroyed? The old ideas about cultural collapse are yielding to new ones based on careful investigation on the ground - but also from above. What surprising explanations have we found and are we off base to think that ancient societies such as the Easter Islanders or the classical Egyptians were, in the end, failures? Can what we learn from these histories help predict which...

Keeping Humans in the Loop

9/23/2019

(repeat) 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...

(repeat) 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...

For Good Measure

9/9/2019

The reign of Le Grand K has come to an end. After 130 years, this hunk of metal sitting in a Parisian vault will no longer define the kilogram. The new kilogram mass will be defined by Planck’s constant, joining three other units for redefinition by fundamental constants. But as we measure with increasing precision – from cesium atomic clocks to gravitational wave detectors able to measure spacetime distortions to 1/1000th the width of a proton – is something fundamental lost along the way?...

Skeptic Check: Data Bias

9/2/2019
More
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. Guests: Caroline Criado-Perez - Invisible Women: Data Bias in a World Designed for...
