Body Electric: How AI is changing our relationships

Hey, Short Wavers! Today, we have a special present for all of you: An episode from our good friends at NPR's Body Electric podcast all a bout artificial intimacy! Thanks to advances in AI, chatbots can act as personalized therapists, companions and romantic partners. The apps offering these services have been downloaded millions of times. If these relationships relieve stress and make us feel better, does it matter that they're not "real"? On this episode of Body Electric, host Manoush Zomorodi talks to MIT sociologist and psychologist Sherry Turkle about her new research into what she calls "artificial intimacy" and its impact on our mental and physical health.

Ghost particles are blasting through you. Can they solve an antimatter mystery?

At the beginning of the universe, annihilation reigned supreme. Equal amounts of matter and antimatter collided. There should have been nothing left. And, yet, here we all are. Matter won out. The question is: why? Scientists are probing the mysteries of a ghostly subatomic particle for answers. To do it, they'll need to shoot a beam of them 800 miles underground.

If you picked up a Honeycrisp apple at a grocery store in New York... and then a Honeycrisp in Texas... and then a Honeycrisp in California... they'd all be the exact same genetically. That's because they're all from the same original plant. Stan Dzugan/Getty Images hide caption

From Honeycrisp to Red Delicious — love it or hate it, your apple is a clone

What's your favorite apple? Maybe it's the crowd-pleasing Honeycrisp, the tart Granny Smith or the infamous Red Delicious. Either way, before that apple made it to your local grocery store or orchard it had to be invented — by a scientist. So today, we're going straight to the source: Talking to an apple breeder. Producer Hannah Chinn reports how apples are selected, bred, grown ... and the discoveries that could change that process. Plus, what's a "spitter"?

In his book Why We Die, author Venki Ramakrishnan looks at modern biological research to understand why our bodies age — and eventually die. "It's a peculiar situation because we're a collection of cells and when we're alive, millions of our cells are dying. ... When we die, most of our cells are still alive," says Ramakrishnan. "And so what does it mean to say you die?" cooperr007/Getty Images hide caption

A microbiologist explains why we age and die

Humans have seen a significant increase in life expectancy over the past 200 years — but not in overall lifespan. Nobody on record has lived past 122 years. So, for this early Halloween episode, host Regina G. Barber asks: Why do we age and why do we die? Microbiologist Venki Ramakrishnan explains some of the mechanisms inside of our bodies that contribute to our decay — and tells us if it's possible to intervene in the process.

The small team caring for some of the last of Hawaii's native snail species

More than a million species are at risk of extinction, many within decades, because of human actions. Among them? The kāhuli, Hawaii's native tree snails that are some of the most endangered animals on the planet. At one point, there used to be about 750 species of snails in Hawaii — almost all of them found nowhere else. Now, they are rapidly disappearing. NPR climate reporters Lauren Sommer and Ryan Kellman join host Emily Kwong to tell the story of the small team caring for the last of some of these snail species — and their fight against extinction.

For the first time in decades, we have a new kind of schizophrenia drug

For the past 70 years, schizophrenia treatments all targeted the same chemical: dopamine. While that works for some, it causes brutal side effects for others. An antipsychotic drug approved last month by the FDA changes that. It triggers muscarinic receptors instead of dopamine receptors. The drug is the result of a chance scientific finding ... from a study that wasn't even focused on schizophrenia. Host Emily Kwong and NPR pharmaceutical correspondent Sydney Lupkin dive into where the drug originated, how it works and what it might shift for people with schizophrenia.
