How Many Naps a Day?!

Researchers found that chinstrap penguins take more than 10,000 naps a day!

These penguins know how to get their rest!

Except for a possible afternoon nap, most people get all their sleep overnight. But chinstrap penguins get their rest in a very different way. Scientists say these birds take more than 10,000 naps a day!

Scientists learned about this surprising sleep pattern by studying a group of chinstrap penguins in Antarctica. In addition to filming the birds, scientists placed devices in the neck and brain muscles of 14 penguins so they could record any brain activity related to sleep. They found that the penguins took 10,000 very short sleeping periods called microsleeps. Each little nap was only four seconds long! But all that dozing adds up—chinstrap penguins end up getting 11 hours of sleep every day.

This sleeping pattern may seem odd, but scientists say it probably helps the penguins survive. Chinstrap penguin eggs and chicks are often hunted by other bird species. When one penguin parent leaves the nest for days to do some hunting over the ocean, the other parent must guard the eggs or chicks alone. It wouldn’t be very safe for a protective penguin parent to relax into a long snooze.

Did You Know?

Sleep helps our brains take in and store new information. How much sleep do we need?

Adult humans need between seven and nine hours of sleep per night. Teens need eight to 10 hours each night, and kids aged 6 to 12 need nine to 12 hours.

Don’t Sleep on These Facts!

Not all animals sleep in the same way. For proof, just read the article about chinstrap penguins farther up on this page! But almost all animals need to sleep. Here are some surprising facts about animals and sleep.

Koalas sleep for up to 22 hours a day—more than any other animal! 

Giraffes sleep for about four and a half hours a day.

Cows can sleep while standing up. (They lie down when it’s time to sleep deeply.)

Dolphins rest only one half of their brains at a time, so the other side can stay awake and aware of predators.

Scientists think animals sleep to restore their brains, but a recent study found that even animals without brains, like jellyfish, seem to sleep. That means we still have a lot to learn about the purpose of sleep!

LeVar Burton’s Next Story

In actor LeVar Burton’s podcast, sounds have gone missing. Can Burton and Detective Hunch solve the mystery?

Actor and director LeVar Burton has always loved a good story, and he knows that kids do, too. Burton’s new podcast, Sound Detectives, is a juicy mystery series that has kids listening closely.

In the podcast, Burton is getting ready to open the Museum of Sound, which celebrates all the wonderful sounds in the universe. When he discovers that some sounds have been separated from their sources, he hires Detective Hunch to find them. With help from a giant ear named Audie, Burton and the detective work to track down those sounds…and catch the thief who has been stealing them. 

Burton first became famous when he played Kunta Kinte, a man who was captured and then enslaved, in the 1977 TV miniseries Roots. Since then, he has had numerous acting roles. Star Trek fans know him as Geordi La Forge in the TV series Star Trek: The Next Generation.

But Burton is equally well known as the host of a kids’ TV series called Reading Rainbow, which ran from 1983 to 2006. In that show, Burton read and recommended fantastic books, inspiring many kids to become enthusiastic readers. Today, many of those same kids (who are now adults) listen to LeVar Burton Reads, a podcast on which Burton reads stories out loud.

Sound Detectives is Burton’s first podcast for kids. He hopes it will take listeners on a great adventure and inspire them to keep exploring.

“[Sound Detectives] appeals to the…curiosity in a child about the world around them,” Burton told the New York Times. “It introduces them to parts of the world that they might not have yet been exposed to.”

Sounds on Mars are different from sounds on Earth. That’s because the atmospheres of the two planets are very different. Thanks to a rover (robot) named Perseverance, which is exploring Mars and recording sounds, NASA is getting some idea of what things sound like on the Red Planet.

Chester Keene Cracks the Code, by Kekla Magoon

Chester Keene’s dad is a spy who works for the government. Other than that, Chester’s life is predictable—and that’s the way he likes it. But when Chester and his friend Skye begin to unravel a mystery wrapped in a puzzle, they realize they need to act fast in order to stop a robbery.

The Area 51 Files, by Julie Buxbaum

Sky Patel-Baum and an odd cast of characters (including a hedgehog) set out to investigate a top-secret government military base called Area 51. Just as Sky suspected, the place is full of aliens! But when the creatures start to disappear, she needs to find out why.

Ghosts in the Gallery, by Barbara Brooks Wallace

In the 1800s, an orphan named Jenny is sent to live with her grandfather, who she’s never met, in a big, gloomy house. But instead of her grandfather, she finds an uncle who claims he’s never heard of her and makes her live in the spooky cellar. Does Jenny belong here? Who is she, and who are the people in this strange, scary home?

Mickey Mouse Enters the Public Domain

A black and white Mickey Mouse wears a hat and holds onto the wheel of a boat.

Mickey Mouse Enters the Public Domain

An early version of Mickey Mouse is now available for anyone to use in their creative work.
A black and white Mickey Mouse wears a hat and holds onto the wheel of a boat.
The Walt Disney Company

Mickey Mouse has changed a lot since 1928, when he appeared in the movie Steamboat Willie.

For 95 years, Mickey Mouse was owned by only one company—Disney. By law, no one else was allowed to make money selling pictures or movies featuring the famous character. But now that’s changed. Mickey, or at least one version of him, is in the public domain. In other words, he’s basically public property.

To understand what that means, let’s go back to 1928—just over 95 years ago. That year, Walt Disney created Mickey Mouse and made a movie about him called Steamboat Willie. Disney asked the U.S. government to copyright Mickey Mouse, which meant that no one else could copy the character. Anyone who did would be breaking the law. But under U.S. law, some older creative works—including art, books, movies, and fictional characters—can be copyrighted for only 95 years. After that, they enter the public domain, and anyone can copy them. On January 1, 2024, many creative works entered the public domain. Steamboat Willie’s Mickey Mouse was one of them.

The Walt Disney Company

Watch a short clip from the 1928 movie Steamboat Willie, starring Mickey Mouse.

Not every version of Mickey Mouse is in the public domain. Mickey has changed a lot over the years. Today’s Mickey Mouse has larger eyes than the original, and he wears gloves. The modern Mickey Mouse is still under copyright.

Now that the 1928 Mickey Mouse is in the public domain, experts say he can appear in books and movies, on T-shirts, and more without permission from the Walt Disney Company.

November 18 is Mickey Mouse’s birthday. The movie Steamboat Willie opened on that day in 1928. This was Mickey’s third movie, but it was the first one to be successful.

When Cartoons Began

If you love Pixar and Disney movies like Toy Story and Moana, check out Fantasmagorie. This short animated movie was released in 1908, not long after movies were invented. Fantasmagorie is totally silent. (No one figured out how to add a full soundtrack to a movie until the 1920s.) But it does show drawings that appear to move, just like today’s cartoons!

A House Full of History

Martin Luther King, Coretta Scott King, John Lewis, and other civil rights activists walk down a street, some carrying American flags.

A House Full of History

Martin Luther King, Jr., his wife Coretta Scott King, and other civil rights activists march from Selma to Montgomery, Alabama, to demand equal voting rights.

A house in Selma, Alabama, where Martin Luther King, Jr., planned a famous civil rights march will soon be open to the public. The house will be moved to Michigan to be part of a history museum called Greenfield Village.

Jawana Jackson, who grew up in the house, sold it to the museum so it could be recognized for its part in the civil rights movement. In 1965, when Jackson was 4 years old, King and other civil rights leaders arrived at the house to plan a march from Selma to Montgomery, Alabama.

Jackson’s parents had offered King, an old friend, the use of their home because they knew his work would be important to Jawana’s future.

“[Jawana] and children in this country and all around the world … deserve a better, a more even, a more just society. Whatever we can do to support you, we’re here,” Sullivan Jackson told King, according to the Pensacola News Journal.

Thousands of people took part in three marches from Selma to Montgomery. These events helped lead U.S. lawmakers to pass the Voting Rights Act of 1965, which protected voting rights for Black Americans.

People will be able to visit the home where these marches were planned after it is moved to the museum in Michigan. Jawana Jackson says she wants the public to be able to see where King did some of his most important work.

“It became increasingly clearer to me that the house belonged to the world,” Jackson told the Associated Press.

Greenfield Village is a history museum in Michigan that contains more than 80 historic structures. Soon, the Jackson home will be one of them. Officials are dismantling the home so it can be transported to Michigan, where it will be rebuilt. Once open to the public, the home will contain some of King’s neckties and pants, as well as furnishings dating back to 1965.

The home is expected to open in the next three years.

Did You Know?

Greenfield Village includes a laboratory used by Thomas Edison, a courthouse where Abraham Lincoln tried cases as a young lawyer, and the building where the Wright brothers built, sold, and repaired bicycles.

Making MLK Day a Reality

Coretta Scott King was an activist in the civil rights movement whose work helped bring about Martin Luther King, Jr., Day.

January 15, 2024, is Martin Luther King, Jr., Day, a U.S. holiday that marks King’s birthday. How did his birthday become a national holiday?

U.S. congressman John Conyers introduced a bill to honor King’s birthday in April 1968, not long after the civil rights leader was killed. But before a bill can become a law, it needs support from members of Congress. There was not enough support at the time, and the bill didn’t pass. Conyers would reintroduce the bill every year.

During the 1970s, due partly to the hard work of King’s widow, Coretta Scott King, public support for the bill grew stronger. Congressional support also increased. By 1979, the bill had support from U.S. president Jimmy Carter and a petition with 300,000 signatures. Again, Congress voted on the bill. It lost by five votes.

By 1983, public support for formal recognition of King was overwhelming. That year, both houses of Congress voted to make the third January of each year Martin Luther King, Jr., Day. President Ronald Reagan signed the bill into law on November 2, 1983.

Artist Creates a Chocolate Wonka

Artist Creates a Chocolate Wonka

Willie Wonka is the most famous chocolate maker in fiction. No wonder an artist made a statue of Wonka out of chocolate!

Sculptor Jen Lindsey-Clark (right) helped unveil the chocolate Willie Wonka in London’s Trafalgar Square.

An artist recently unveiled a statue of legendary candy maker Willie Wonka that’s made entirely of chocolate! The statue was created in honor of the opening of Wonka, a movie about the character as a young man.

Chocolate sculptor Jen Lindsey-Clark spent more than five weeks making the sculpture, which is 6 feet, 2 inches (188 centimeters) tall and weighs 220 pounds (100 kilograms). She crafted everything from chocolate, including the top hat, the buttons, and the shoelaces.

Even the statue’s shoelaces are made of chocolate!

Lindsey-Clark said she was thrilled to do it. She’s loved chocolate ever since she made pretend-chocolate mud pies as a kid. Today, she’s a renowned chocolate artist. She even made a sculpture to look like England’s King Charles III when he was coronated (crowned).

Lindsey-Clark is also a fan of Willie Wonka, a character that first appeared in the Roald Dahl book Charlie and the Chocolate Factory. Since then, Wonka has been at the center of three movies, including Willie Wonka and the Chocolate Factory, the 1971 film that starred Gene Wilder as Wonka.

“From the minute I saw it, I had to watch it at least three times a year. It’s just the most magical, beautiful movie,” she told the British Broadcasting Corporation (BBC).

The sculpture was unveiled in Trafalgar Square in London, England’s capital city. It’s been moved since then to keep the public from taking any nibbles!

Sculptor Jen Lindsey-Clark didn’t leave out a single detail.

Did You Know

It’s possible to buy dark chocolate, milk chocolate, and white chocolate. The main difference between them is the amount of milk and cocoa they contain. Since white chocolate does not contain cocoa powder, some people say it’s not really chocolate.

Every Brain Is Different

A new book by Temple Grandin takes a look at the different ways different people think.

Have you ever noticed that some people are fantastic artists, while others have a way with words? Still others work well with their hands. Why aren’t we all good at the same things? A new book for young readers can help answer that question.

Titled Different Kinds of Minds, the book is about how each person thinks differently. Its author, Temple Grandin, hopes it will inspire kids to explore how they think and figure out the things they’re great at.

Grandin is known for her studies of animal behavior and for designing devices that allowed farm animals to be treated more humanely. She has also spoken and written about her experiences as a person with autism. Growing up, being autistic made her aware that everyone has their own way of taking in information.

In the book, Grandin explains the different ways people think. She is a visual thinker, which means when she has a thought and idea, she pictures it in her mind. Some people are pattern thinkers, which means they may be good at things like math and music. And some people are verbal thinkers, which means they’re good with words and remember information best by reading it or hearing it read to them. Many people can think in more than one way, but there’s probably one way of thinking they do best.

You can read more about types of thinking farther down on this page.

Grandin hopes to encourage young readers to consider how they think best and explore ways to make the most out of their incredible brains.

No matter how you learn information, your brain is amazing. Scientists say that the human brain has nearly unlimited storage space for new information!

Thinking Differently

In Different Kinds of Minds, Temple Grandin writes about three kinds of thinkers. Below, you can read a little bit more about each one. Grandin says most people can think in more than one way, but there’s usually one way they’re best at.

Visual Thinkers

Visual thinkers learn best by looking at pictures or diagrams instead of reading words. They’re often talented artists and usually have mechanical skills, such as the ability to design and build machines. Many inventors are visual thinkers.

Pattern Thinkers
Pattern thinkers think in patterns, or information that repeats in a predictable way. They are often good at math, music, or both—areas that have a recognizable set of rules. Pattern thinkers may be good at games like chess.

Verbal Thinkers
Verbal thinkers often think in words instead of pictures or patterns. They may like to read stories and facts, and they often have a great talent for memorizing what they’ve read. These thinkers may learn best by reading information and writing things down.

Animals Get Silly

The Comedy Wildlife Photography Awards recognize the images that show wild animals in their silliest moments.

Jason Moore of Australia won the top prize for his photo of a kangaroo that looks like it’s playing air guitar.

Have you ever done something funny without even trying? Wild animals do that sometimes, too! The annual Comedy Wildlife Photography Awards capture the hilarious things critters do when they think no one’s looking. This year’s winning snapshot shows a kangaroo that looks like it’s playing air guitar. But the kooky kangaroo didn’t take home the only prize.

The Comedy Wildlife Photography Awards are open to anyone, whether they are a professional photographer or just take photos for fun. The key is to capture an image of wildlife at its wackiest. Winners are chosen in six categories: Creatures of the Land (land animals), Creatures in the Air (flying animals), Underwater, Junior (for photographers who are 18 and younger), Internet Portfolio (for a group of four photos), and Video Clip (for a video of a funny animal). Judges also choose an overall winner, and the public gets to vote on a People’s Choice Award

© Lily Bernau/Comedy Wildlife 2023

The winning video, called Too Cold, was taken by Lily Bernau in Antarctica.

In 2023, 1,842 people from 85 countries sent in thousands of images, but only a few of them won awards. The picture of the arm-swinging kangaroo, called Air Guitar Roo, and its photographer, Jason Moore of Australia, won the Overall category and the Creatures of the Land category.

The public had a different favorite. The People’s Choice was an image called Dispute, which shows two greenfinches (a type of small bird) that look like they’re arguing. Dispute and its photographer, Jacek Stankiewicz of Poland, also won in the Junior category.

Toys R Us, which once was the biggest toy seller in the United States, is making a comeback! The company has already opened several new stores, and many more are planned for 2024.

In November 2023, Toys R Us opened a large store in the Mall of America in Minnesota, two years after opening a large location at American Dream, a shopping mall in New Jersey. In the past three years, the company has also opened smaller stores on cruise ships, in airports, and inside Macy’s department stores. Toys R Us is growing—not long after many people thought it might disappear forever.

Toys R Us was founded in 1957 and was successful for many years. But six years ago, Toys R Us declared bankruptcy, which means that it owed more money than it could pay back. Many people were choosing to buy toys online or at stores like Walmart instead of Toys R Us. Hundreds of Toys R Us stores closed.

In 2021, an organization called WHP Global decided Toys R Us could be saved. WHP Global puts money into companies with the hopes of making more money—and it decided to put money into opening new Toys R Us stores. Its goal was to get people to want to shop at Toys R Us instead of other places.

One way to get people to go somewhere is to make it fun. Many of the new stores aim to do just that! For example, the Toys R Us at American Dream has a two-story spiral slide, an ice cream parlor, and places where kids can try out some of the toys.

Will the fun be enough to keep Toys R Us in business? Decide for yourself! The slideshow below shows what you might find if you visit a new Toys R Us store.

Solve…Then Sleep

A new study found that practicing math before bed may help people remember it later.

Bedtime may be the best time to learn and remember math! In a new study, scientists found that people who learned new math problems just before going to sleep remember them better than if they learned them during the day.

For the study, scientists in the United Kingdom asked 77 adults to learn multiplication problems at two different times of the day. They learned some problems during the day and other problems just before bed. About 10 and a half hours after the adults learned the problems, scientists tested them. The adults remembered the bedtime problems better.

The results of the study are similar to other studies that have been done with children. In 2015, scientists had parents of first graders tell their kids bedtime stories with a math theme. The scientists found that those first graders had higher math scores during that school year than first graders who didn’t hear math bedtime stories. 

Why does bedtime learning seem to be effective? Scientists aren’t sure. They know that the brain makes certain connections during sleep that help us lock in what we’ve learned. But it’s also possible that when we learn something during the day, it becomes harder to remember as we learn other new things later that day. When we’re asleep, our brains have nothing to lock in except what we just learned before bed.

Bedtime Is Cleanup Time

How does sleep help us lock in memories? It’s all in our brains.

When you learn something new, at home or at school, the information gets stored in a part of your brain called the hippocampus. But it can’t stay there forever. Like a smartphone or a kitchen cabinet, the hippocampus has only a limited amount of space. So if you learn more than it can hold, you’re not going to remember it. Or you’ll forget something else you learned that day as your hippocampus makes space for the new information.

When you sleep, your brain does a big cleanup. It gets rid of memories you don’t need, like which shirt you wore two days ago. The important stuff gets locked into a different part of your brain, where it can stay. And the next morning, the hippocampus has space for new information.

Climbing for a Cause

Climbing for a Cause

Ten-year-old Luke Mortimer climbed a mountain to raise money for children with disabilities.

Luke Mortimer during his climb up a peak called Embsay Crag, on November 4, 2023.

When he was 7 years old, Luke Mortimer lost his arms and legs after an infection. Three years later, he climbed a mountain near his home to help other children with disabilities.

Luke, who lives in the United Kingdom, set his sights on the 656-foot (200-meter) peak called Embsay Crag in 2019, when his family moved into a home nearby.

“When we moved here, we were going down the road to Embsay, and I just saw the crag, and I said, ‘Mum, dad, one day can we climb it?’” Luke said before his 2023 climb. “It’s been a few years now, but I feel very determined about getting to the top and back down. I think the worst thing that can happen is probably rain.”

The climb wasn’t just a personal challenge. Luke set it up as a fundraiser—a way to help others after so many people helped him. The Mortimer family had received many donations to pay for Luke’s prosthetics, or artificial limbs, as well as for changes to the Mortimer home that help Luke get around more easily. So, Luke thought, why not use the climb to raise money for other kids with disabilities?

Many people joined Luke when he climbed Embsay Crag.

The Mortimer family announced that anyone could join them on their climb. Forty people traveled from across the U.K. to take part. And while Luke had hoped to raise 500 British pounds (about 613 U.S. dollars), he ended up raising more than 12,000 pounds (nearly 15,000 U.S. dollars)!

“It was tiring and tough, but when I got to the top I was very proud of myself. Everybody was really kind for coming out to support me,” Luke told Metro.

The Paralympic Games is an international sports competition for people with disabilities. The Paralympics take place right after the Olympics Games, in the same host city. 

The most successful athlete in the history of the Paralympics is swimmer Trischa Zorn, who has won 55 medals, including 41 gold medals. Zorn was born with an eye condition that left her blind. She last competed in the Paralympics in 2004 and works as an attorney (lawyer) today.
