Who decides what robots look like?

Who decides what robots look like? How do robots work and move? How are they controlled? And are robots alive? We tackle all your robot questions in this episode, and we’re taking a field trip to a local factory that uses hundreds of robots to help humans do their jobs. GlobalFoundries, in Essex Junction, Vermont makes microchips that go in all kinds of electronics. In fact, if your adults have a smartphone, more than likely it has a chip made at this very facility. Engineers Adrien Plouffe and Lucy White work with the robots at GlobalFoundries and answer your questions about robots, including: Why are robots made of metal? Why do people like robots? Do robots cry?

Why can’t animals talk to us?

Why can’t animals talk to us? Are humans the only animals that can talk? Can different species of animals communicate with each other? We learn about animal communication with Arik Kershenbaum, author of [Why Animals Talk: The New Science of Animal Communication.] (https://www.goodreads.com/book/show/201751094-why-animals-talk) He studies wolves, gibbons, dolphins and hyrax to learn how they communicate. Also in this episode: why are parrots able to speak human words but other birds can’t?

Why do we have anxiety?

Why do we worry and how can we deal with it? Why do we get anxious? Where does anxiety come from? Anxiety or worry is a hard feeling to overcome, but it’s a universal human emotion. In this episode, we explore anxiety with clinical psychologist Eileen Kennedy-Moore, also known as [Dr. Friendtastic] (https://drfriendtastic.com/) . She helps us understand why moderate anxiety is useful and necessary. But too much worry can prevent you from learning new things or doing activities that could be fun. And she has some tips for how to overcome anxious feelings.

How do we vote?

Election Day in the United States is November 5 this year and election officials across the country are already hard at work setting up polling places and processing mail in ballots. Even if you’re not old enough to vote, you can be part of the process. You can watch voting machines be tested, observe the polling places on Election Day, or even watch votes be counted once the polls close. (Sometimes there are livestreams so you can watch from the comfort of your own home!) For this episode on how voting works, But Why stopped by the South Burlington City Hall on the day vote tabulators were being prepared. Plus we meet Vermont’s top election official, Secretary of State Sarah Copeland Hanzas. Have you asked an adult to take you to the polls yet?

How do broken bones heal?

Why do we have bones? How do they grow–and how do they know when to stop growing? How many do we have in our bodies? And when we break our bones, how do they heal? What do casts do? And how do you know if you’ve broken a bone? Broken bones are a common occurrence in kids. Up to 40% of girls and up to 50% of boys will break a bone in their lifetime. In this episode, we learn about the role of bones in our body and how to deal with a fractured bone with Melissa Raddatz, a family nurse practitioner at Duke Health System in North Carolina.

How do we learn to swim?

But it’s important to know how to swim if you’re going to be around water! In this episode, Upper Valley Aquatic Center Swim School Director Kana Wyman gives us swimming tips, like how to get comfortable putting our heads in the water, how to float and more. Download our learning guides: [PDF] (https://npr.brightspotcdn.com/76/d2/c494086e4b9f821111f8aa2a3585/how-do-we-learn-to-swim.pdf) | [Google Slides] (https://docs.google.com/presentation/d/19YbphH_wLQfpqO2C83GFTTD2_TGjHU3RLdI2_V-WU-M/copy) | [Transcript] (https://npr.brightspotcdn.com/89/b1/d4af4ccc4ebdbc6c6bbecd478ca3/butwhy-swimming-ep240-transcript.pdf) A few tips for getting started: ---If you don’t live near a pool or body of water, you can learn some primary skills even in a bathtub or using a bucket. ---Get used to putting your face in the water by using a bucket or big bowl. Keep your mouth closed and blow air through your nose. Humming can help make sure you’re breathing out. ---When floating, think about a string pulling your belly button up to the sky. It’s easier to float if you spread your body out, rather than curling into a ball. You may need to swirl your arms or legs to keep your whole body on top of the water. ---Some people have a harder time floating than others, due to body mass differences. So if it feels hard, it’s not your fault! ---Check with community swimming pools to see if they offer free lessons. Many pools, gyms or swim schools will offer lessons for kids and adults that are free or subsidized, at least occasionally, to make sure everyone has the opportunity to learn lifesaving swimming skills. ...

Do people eat bugs?

Yes! In many parts of the world, insects are a regular part of people’s diets. Bugs are an efficient source of protein, and many cultures find them delicious. Some countries, like the US, don’t have a strong culture of insect cuisine, but that’s starting to change as people look for ways to feed a growing global population without using as many resources as we currently do. So insects might be an important part of our future diets as well. With all the talk about cicadas this summer, eating bugs has been making news for adults. So, in this bonus episode, But Why learns about cooking up insects with Joseph Yoon, edible insect ambassador at [Brooklyn Bugs] (https://www.brooklynbugs.com/) .

Why do cicadas come out every 17 years?

This spring, trillions of periodical cicadas are emerging from the ground, where they’ve spent 13 or 17 years feeding on xylem (basically, tree juice). The two specific broods emerging this year have not come out at the same time since 1803, and kids may be hearing a lot of news about these loud insects. So today we’re tackling the cicada questions you’ve sent us: Why do cicadas come out every 17 years? What do cicadas eat? Why are there more cicadas at night than in the morning? Why do cicadas molt? How do cicadas get babies? We speak with Dan Gruner, professor of entomology at the University of Maryland, to get answers.

What's cool about cockroaches?

That’s a question a lot of people have, honestly. But a kid named Rosie was bold enough to ask us to investigate why. So, in the latest episode, we dig in on why cockroaches get such a bad rap and why you might want to reconsider if you’re not a fan. Only two percent of the world’s cockroaches are considered pests. Those are the ones that can live in houses and potentially make us sick. But the vast majority of cockroaches don’t bother humans at all! Some, like the social cockroach species known as termites, work to decompose organic material and are hugely important to our environment. So where do people learn negative attitudes toward insects? We dig deep into insects with Jessica Ware, an entomologist and curator at the [American Museum of Natural History] (https://www.amnh.org/exhibitions/permanent/gilder-center/insectarium) . She’s also the host of the [PBS digital series] (https://www.pbs.org/show/insectarium/) [Insectarium] (https://www.pbs.org/show/insectarium/) .

What is a solar eclipse?

A solar eclipse is coming to North America on April 8, 2024. The moon will line up perfectly between the Earth and the sun, blocking out the sun’s light and casting a shadow that will pass over parts of Mexico, the United States and Canada. People in the path of totality will experience a few minutes of darkness during the day as the moon perfectly covers the sun. Those not in the path of totality in those countries will still experience a partial solar eclipse. In this episode, we’re answering questions about the eclipse and talking about how to keep your eyes safe if you’re watching it! We speak with Bridgewater State University solar physicist Martina Arndt, Fairbanks Museum planetarium director Mark Breen and Thomas A. Hockey, author of America’s First Eclipse Chasers.

How do invasive species take over?

Why are there Burmese pythons and chameleons in the Florida Everglades? We might not know how those animals arrived but they are causing damage to the natural ecosystem. An invasive species out competes native plants and animals in an ecosystem. So how does this happen?
