Perpetual Emotion Machine [rebroadcast] 2020-01-13 07:14:06 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. Guests:
Rosalind Picard - Professor at the MIT Media Lab and co-founder of the companies Affectiva and Empatica.
Robert Sapolsky - Professor of neuroscience at Stanford University, and author of Behave: The Biology of Humans at Our Best and Worst. 50 minutes, 31 seconds
Your Brain's Reins [rebroadcast] 2020-01-06 07:37:11 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 if your brain is intact and your only task is choosing a sock color, are you really in control? How your unconscious directs even mundane behavior ... and how you can outwit it. Guests:
Kevin Davis - Author of The Brain Defense: Murder in Manhattan and the Dawn of Neuroscience in America's Courtrooms
Hilarie Cash - Co-founder and chief clinical officer of reSTART, an internet addiction recovery program
Adam Alter - Assistant professor of marketing and psychology at New York University, Stern School of Business, and author of Irresistible: the Rise of Addictive Technology and the Business of Keeping Us Hooked

Skeptic Check: Heal Thyself [rebroadcast] 2019-12-30 10:34:20 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 fighter about ignoring the findings of medical science. And, if AI can diagnose better than an MD, will we stop listening to doctors altogether? It's our monthly look at critical thinking ... but don't take our word for it! Guests:
Katherine Foley - Science and health reporter at Quartz, and author of the article "Alexa is a Terrible Doctor"
Paul Offit - Professor of pediatrics at the Children's Hospital of Philadelphia and the Perlman School of Medicine at the University of Pennsylvania, and author of "Bad Advice: Or Why Celebrities, Politicians, and Activists Aren't Your Best Source of Health Information"

Waste Not 2019-12-16 08:29:40 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.

#547 The D Factor: The Dark Side of Your Personality This week on Science for the People, we're discussing dark personality traits. Everyone has them, and how they manifest themselves depends on your "D" level. We'll be speaking with Ingo Zettler, a Professor of Psychology at the University of Copenhagen and a member of the team of researchers who put forward the theory of the common core of dark personality traits, about what the "D" factor is and what influences your "D" level.

Man Against Horse This is a story about your butt. It's a story about how you got your butt, why you have your butt, and how your butt might be one of the most important and essential things for you being you, for being human.
