One in four U.S. households experiences a power outage each year. Scientists at Oak Ridge National Laboratory are working on technology they hope will help fix electric grids: drones. They're betting that 2-ft. large drones connected to "smart" electric grids are a cost-effective step to a more electrified future.

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.

For years, we've been asking, "Which came first: the chicken or the egg?" Maybe what we should have been asking is, "Which came first: the frog or the tadpole?" A new paper in the journal Nature details the oldest known tadpole fossil. Ringing in 20 million years earlier than scientists previously had evidence of, this fossil might get us closer to an answer.

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"?

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.

Every American red wolf alive right now is descended from only 14 canids. In the 1970s, humans drove the red wolf to the brink of extinction. Because of that, red wolves today have low genetic diversity. But what if we could recover that diversity ... using "ghost genes"?
That's right, today's episode is a ghost story. Along the way, we get into gene dictionaries, the possibilities of poo and how a photo of a common Texas coyote started it all.

This mission is designed to tell scientists more about the structure, the interior and the habitability of Europa, one of the four large moons of Jupiter. Host Regina G. Barber talks with astrobiologist and friend of the show Mike Wong about why their mutual love for this fascinating moon and what it means for the search for life outside of Earth. Plus, they talk about other icy moons that may also have the trifecta of ingredients needed to sustain life: liquid water, specific elements and an energy source.

Lightning: It happens all the time, and yet the exact details of how it's made has long eluded scientists. That is, until now. New research out this week in the journal Nature holds new insights into the precursor to lightning. To figure it out, researchers flew a NASA ER-2 - essentially the research version of a spy plane - over several tropical thunderstorms. What they found: The same high energy radiation is found in places like neutron stars and around black holes.

At first glance, the whole narrative of aquatic invasive species may seem straightforward: A bad non-native species comes into a new ecosystem and overruns good native species. But the truth? It's a little more complicated. To tear down everything we thought we knew about invasive species and construct a more nuanced picture, host Emily Kwong talks to experts Ian Pfingsten, who works on the United States Geological Survey's Nonindigenous Aquatic Species Database, and Nicholas Reo, a Canada Excellence Research Chair in Coastal Relationalities and Regeneration.

The research presents an intriguing possibility that this style of communication may have evolved before humans split off from great apes, and tells researchers more about how turn-taking evolved.

More than a hundred years ago, a British engineer proposed linking two rivers in India to better irrigate the area and cheaply move goods. The link never happened, but the idea survived. Today, due to extreme flooding in some parts of the country mirrored by debilitating drought in others, India's National Water Development Agency plans to dig thirty links between rivers across the country. It's the largest project of its kind and will take decades to complete. But scientists are worried what moving that much water could do to the land, the people — and even the weather. Host Emily Kwong talks to journalist Sushmita Pathak about her recent story on the project.

With them came solar flares that kicked off a severe geomagnetic storm. That storm is expected to last throughout the weekend as at least five coronal mass ejections — chunks of the sun — are flung out into space, towards Earth! NOAA uses a five point scale to rate these storms, and this weekend's storm is a G4. It's expected to produce auroras as far south as Alabama. To contextualize this storm, we are looking back at the largest solar storm on record: the Carrington Event.
