Short Wave

At Short Wave, we love a good brain. Which is why we’ve had a lot of conversations over the years with NPR’s neuroscience reporter, Jon Hamilton. Jon’s been writing about brains for over 15 years, from tiny brain organoids that grow in a dish, to fruit fly brains, mouse brains and some really memorable human brains. But Jon is retiring, so today on the show he joins us to share the most memorable brains he’s come across in the past couple of decades. Interested in more brain science?

In the age of AI, what differentiates humans from robots? What makes humans … human? To find answers, many people are studying consciousness: our capacity for experience. But doctors and researchers still have a long way to go when it comes to finding new ways to detect consciousness in humans — much less computer software. That gets especially tricky when people are unable to use their words or bodies to tell others whether or not they’re conscious, like in vegetative states. Today on Short Wave, how some researchers are finding ways to get around those limitations. Interested in more tech episodes?

A valuable NASA satellite observatory is falling to Earth faster than scientists expected. It’s called the Neil Gehrels Swift Observatory, or “Swift” for short, and it can respond to celestial events much faster than its sky-gazing counterparts. To save Swift and test out a first-of-its-kind technology, NASA partnered with an Arizona-based startup to launch a refrigerator-sized robot, aptly named Link, into lower Earth orbit. That’s on its way right now to meet up with Swift to give it a boost.Interested in more science in the news?

Taking an air taxi to the airport may become as simple as ordering a ride share today. In our first episode in our summer series Tech Camp, we explore how a futuristic vehicle that transforms from helicopter to propeller plane is already taking flight in New York and San Francisco. This new kind of commuting might be here sooner than you think: A law just went into effect to build infrastructure for them in places like airports. Short Wave host Regina Barber speaks with the startup Joby and Georgia Tech aerospace experts about the safety, the science and what an actual ride would look like from app to air. Plus, we get into the history of the air taxis of the past and why those airlines no longer exist.Interested in more tech episodes?

The U.S. generates 292 million tons of trash each year – and that trash has to go somewhere. Sometimes, that’s to an incinerator, where it’s burned and turned into electricity. Proponents of incineration applaud the ability to generate energy from waste and divert garbage from landfills. Opponents worry about the potential health risks, especially to minoritized communities. Today on the show, we explore the good and the bad of waste-to-energy facilities – and even get to see one up close.Interested in more deep dives into the often invisible science powering our lives?

For many, being able to work from home is a boon: saving time on your commute, working in your sweatpants, throwing in a load of laundry before a meeting. People say it makes them happier. But a new study suggests that, despite all the advantages, working from home isn’t creating a happier workforce. It’s making people more socially isolated. We get into all the details with NPR mental health correspondent Rhitu Chatterjee.Interested in more everyday science?

The Ebola outbreak in the Democratic Republic of Congo is growing – and is likely larger than official numbers show. The deadly disease spreads through bodily fluids, on average killing half the people it infects. And while officially declared in May, the case numbers point to the virus circulating for months without being detected. To make matters worse, there’s not a vaccine for this specific species of ebolavirus – at least, not yet. NPR global health correspondent Jonathan Lambert has been covering everything Ebola-related for the past month or so, and shares what he’s learned today.Interested in more health and science news?

Janet Jones has been fascinated by horses since childhood. She’s now a horse trainer and a neuroscientist, which allows her to explore the minds of the animals to which she’s devoted her life. She even recently wrote a book all about their brains. She says there’s an enormous gap between the way humans have relied on horses for tens of thousands of years – and what we actually know about their brains. And they have lots to teach us humans. That’s why we’re diving into science today. Interested in more science? Email us your question at shortwave@npr.org.Support public media with NPR+ and enjoy perks for over 25 podcasts like this one.

The war in Iran has disrupted the global fuel supply. That has sent airline prices soaring and cancelled scores of flights. This got Short Wave host Emily Kwong wondering: Could another fuel source help take us to the skies? Today on the show, we explore the chemistry and cost of sustainable aviation fuel. Along the way, we highlight two initiatives to create a regional SAF supply – one in Washington and one in Pennsylvania. Interested in more stories about the future of flying?

Could standardizing chocolate help small-scale farmers? Chocolate scientist Julien Simonis thinks it could help persuade consumers to pay for higher quality chocolate, in turn helping out these growers. Every cacao bean is different, and for a long time, there wasn't a standard way of comparing the quality of chocolate. But in 2009, a sustainable agriculture nonprofit started a program called Cacao of Excellence. The goal was to develop a standard way of evaluating cacao just like those sommelier’s do with wine. So today, we’re going behind the scenes of a chocolate laboratory to see just how cacao is evaluated. This story was originally reported for NPR by science correspondent Ari Daniel. Read the full story here.If you liked this episode, check out our episodes on how climate change is hurting chocolate production and how some people are making chocolate alternatives.
