  • Alive Or Not Alive... Is A Tricky Question
    In this Back To School episode we consider the "List of Life": the criteria that define what it is to be a living thing. Some are easy calls: A kitten is alive. A grain of salt is not.But what about the tricky cases, like a virus? Or, more importantly, what about futuristic android robots?As part of our Black History Month celebration, developmental biologist Crystal Rogers and Short Wave co-host Regina G. Barber dig into what makes something alive, and wade into a Star-Trek-themed debate.Listen to Short Wave on Spotify and Apple Podcasts.Is there something you'd like us to cover?

  • The Trait That Makes Robots More 'Human'
    Neurotic, anxious robots like C-3P0 from Star Wars' C-3P0 and Marvin from The Hitchhiker's Guide to the Galaxy are a staple of science fiction — but they're not as common in the real world. Most of the time, the chatbots and artificial intelligence "robots" we encounter are programmed to be extraverted, confident and cheerful. But what if that changed?NPR science correspondent Nell Greenfieldboyce dives into the world of robot personality research and talks to a team of researchers that are experimenting with a very different kind of robot temperament.Read more of Nell's reporting on the topic here.Interested in more science news?

  • Why Gene-Edited Babies May Be Closer Than Ever
    A Chinese scientist, He Jiankui, made a shocking announcement to the world in 2018: He had secretly engineered the birth of the first gene-edited babies. The birth of the twins was seen as reckless and unethical by the scientific community. That’s because, among other things, the CRISPR gene-editing technique Jiankui used was so new. NPR science correspondent Rob Stein has been following the controversial world of gene-editing and human reproduction, including some companies’ recent quests to push gene-editing technology forward.Read more of Rob Stein’s reporting on the topic here.Interested in more science news?

  • Sea Camp: Did Life Start In Hydrothermal Vents?
    How did life start on Earth? The answer is a big scientific mystery scientists are actively investigating. After talking with many scientists, host Regina G. Barber found that an abundance of water on Earth is most likely key, in some way, to the origin of life — specifically, in either deep sea hydrothermal vents or in tide pools. It's for this reason some scientists are also exploring the potential for life in so-called "water worlds" elsewhere in the solar system, like some of the moons of Jupiter and Saturn. This episode, Regina digs into two water-related hypotheses for the origin on life on Earth — and what that might mean for possible alien life.Have another scientific mystery you want us to cover on a future episode?

  • Why Do Some 80 Year-Olds Have Extraordinary Memories?
    The human brain tends to slow down as we age — even healthy brains shrink. That can make learning and memory harder as people age. But some people’s brains shrink more slowly than their peers. This lucky group is called “SuperAgers.” They’re people aged 80 or older. But they have the memory abilities of someone 50-to-60 years old. This week in the journal Alzheimer's & Dementia, researchers from Northwestern University’s SuperAging Program summarized some of the secrets they’ve learned in the last 2.5 decades.  Want to hear about more stories about human health and aging?
