Recently, an app called Peeple got a whole lot of attention for trying to be the Yelp for Humans. But it’s just one in a really long line of apps that try to apply consumer reviews to people.

Every time you go from one country to the next, you cross a border. And that usually means dealing with some kind of border agency that enforces each country’s idiosyncratic rules and regulations. But what if the whole process were standardized and run by a single organization?

Nerf balls are for boys. Dolls are for girls. Romance movies are for women, and action flicks for men. Nearly everything in our world is gendered in some way. But what if we lived in a world where gender was more like hair color — something you could change at will, and that had little bearing on what other people…

A lot of researchers are thinking about how to genetically engineer crops and food animals to help them withstand post-climate change heat and parched conditions. But what about genetically engineering humans to slow our constant carbon contributions?

Scientists now have a way to cloak something very small, making it effectively invisible. But what if scientists and engineers created a much larger version? What if we all had access to invisibility cloaks?

Humans spend a lot of time and energy wondering if there’s anybody else out there. But what if we got unequivocal evidence that there was?

When you were a kid and stole your friends’ toys, your parent probably asked you this angry hypothetical: “How do you think that made them feel?” But what if you actually could feel what another person is feeling? This week, we travel to a future where humans have invented an empathy machine.

Many scientists believe that the Earth is approaching another mass extinction event. Between deforestation, pollution, hunting, and general human encroachment, all sorts of species are at risk of going extinct. In this week’s future, humans give up on saving species where they live and instead put them in armored zoos.

There are a million ways people might use drones in the future, from deliveries and police work to journalism. But in this episode, we’re going to talk about consumer drones — something that you or I might use for ourselves. What does the world look like when everybody with a smart phone also has a drone?

What if “life in prison” could mean 100 or 200 or 400 years? Does that change the way that sentences are doled out? What happens when a person gets out of prison?

The Earth, right now, is revolving around the sun at about 62,000 miles per hour. But what would happen if we slowed to a stop? At that point, the planet would have exactly 64 1/2 days before it crashed into the sun. In this week’s episode, we find out what would happen during those 64 1/2 days.

This week, we go to a world where facial recognition is so good that any company can grab an image of your face while you’re walking down the street, and link it to everything from your social media profiles, to your credit score, to your workplace.

According to the Center for Climate and Energy Solutions, about 2.3 percent of America’s power is generated by wind. But wind power is becoming wildly popular all over the world. What would happen if a company put up so many wind turbines that they actually changed the climate on Earth? That’s the subject of this…

Need to get from New York to Paris? Or San Diego? Chances are, you’re hopping on a plane. But commercial flights aren’t just annoying and expensive — they also input a ton of carbon into the environment, contributing to climate change. So what if we stopped flights to save the planet? What would happen next?

We all want to be our best selves. But what if you could add almost anything to your body and mind? A camera here, an exoskeleton there. This is the world that some biohackers imagine—one in which humans can extend their abilities beyond the limits biology has set for us. But what does that world look like?

Everywhere I go, people are talking trash about Sydney Leroux’s fake eyelashes. To be fair, I’ve been in Canada, where she’s particularly reviled. I get it, she turned her back on you, Canada. You’re hurt. But through the pain, I beg you, do not bring her eyelashes into this. Because let’s be real: those eyelashes are…

We often think of stars as twinkling, harmless little points of light that fill our night sky with majesty. But stars can be dangerous too. When they come to the end of their lifespan, some stars explode fantastically as supernovae. So what would happen if one of those giant explosions happened nearby?

If you’re reading this, you have access to the Internet. But what would happen if the Internet suddenly went away? And what would it take to make that happen? This week’s episode peers into the dark fantasy of many of us who work for the Internet: a world without it.

If there was a drug that meant you never had to sleep again, would you take it? Would those who didn’t need to sleep have special advantages over those who did? All that and a side of zombies, in this week’s episode of Meanwhile in the Future.
