Maybe not, according to AI (artificial intelligence). Fingerprints are formed before birth and are determined partly by your genes, like a zebra’s stripes or a leopard’s spots. They have long been used to identify criminals from prints left at crime scenes.

But new research has shown that AI commonly used for facial recognition is able to identify fingerprints from different fingers that belong to the same person. The AI tool was able to identify whether fingerprints came from the same person with 75-90% accuracy, suggesting strong similarities between the fingerprints. The scientists aren’t sure exactly how the AI tool is doing this, but they hope that it might be able to help solve crimes and free innocent people.

PENGUIN

ARE FINGERPRINTS REALLY UNIQUE?

ck.com

We all know about the importance of a good night’s sleep – broken nights can make you feel tired and grouchy the next day. But some animals prefer to take naps.

Lots of naps. Chinstrap penguins take THOUSANDS of very short naps every day!

Birds often have regular short snoozes, rather than sleeping for a long stretch of time like we do, but chinstrap penguins take more than 10,000 four-second naps a day!

The scientists studying this phenomenon think this might be because the penguins need to stay alert for predators. They’re not missing out on sleep though, because these microsleeps add up to around 11 hours of sleep over 24 hours. © Thap ana_ Studio / Shuttersto

UPSIDE-DOWN ANGLERFISH © Emőke Dénes

Just when you thought anglerfish couldn’t get any weirder, scientists have discovered that one species lives its whole life upside down! These scary-looking fish have luminous ‘lures’ to attract prey towards them in the pitch dark of the deep ocean. Most anglerfish dangle their lures like a fishing rod in front of their faces. But new underwater video footage shows that the whipnose anglerfish swims upside down with their long lures dangling below them. The researchers think this behaviour could allow the fish to attack larger and faster prey without accidentally biting themselves in the process.

time!

By Anna Cla

ybourne

We all know what ‘time’ means, and how we use it in everyday life.

Knowing what time it is means you know when to go to school, a club or a friend’s party… …how long you have to wait…

WHAT IS TIME?

Time is a sequence of events from past to future.

It’s the way things happen one after another – instead of all at once! (Imagine how weird THAT would be!)

Time only goes in one direction. You move forward in time, but not back. You can remember what happened yesterday, but not tomorrow!

But why is that?

After all, we can move around in space. You can go to the shop, then come back. Why doesn’t time work like that?

We only know time is passing because things happen and change.

Imagine nothing happened at all and everything stayed still forever.

Would time still exist… or not?

My brain hurts!

Time is a sequence of things happening one after another – and it can only go forwards!

…and, of course, how old you are!

e, re!

The truth is, even scientists aren’t really sure how time works! There are lots of different ideas about what it is.

I think that time is a real thing that exists in the universe.

No, I’m sure it’s just an illusion, made by our brains!

TIME CAPSULE NOTEBOOK

Send a message to the future by describing your life right now, then storing it away. You could look at it again in a few years, or when you’re a grown-up, to see what’s changed.

Or maybe someone in the future will find it, hundreds of years from now!

Yo u will need

A small notebook (or make one from sheets of folded paper sewn or stapled along the fold) A pen or pencil Sticky tape or glue

What you do 1. Write in your notebook about your life and what it’s like being the age you are now. You could include: Your name and age, where you live, your family, pets and friends.

Your favourite subjects, hobbies, likes and dislikes.

What you plan to do when you grow up.

2. Stick in small, flat everyday items, like sweet wrappers, bus tickets and photos.

3. You can add drawings too, like a map of your street, a plan of your bedroom or a self-portrait.

4. You could even write a message to your grown-up self!

The Earth is 10 billion years old.

time trackinG

Years, months, weeks, days, hours, minutes and seconds – they’re all used to measure time.

But where did they come from?

Time measurements are based on two natural cycles of planet Earth:

The Earth spinning around...

...and the Earth orbiting around the Sun.

One full turn = One day

Then we divide these units into smaller parts:

One full orbit = One year

Unfortunately, a year doesn’t divide exactly into 365 days, which is why we need leap years. Find out more about these on page 19!

TIME LONG AGO

A day is one rotation of the Earth, and a year is one orbit of the Earth around the Sun. 8 whizzpopbang.com

Today, people all over the world use the same time system.

But long ago, people in different parts of the world weren’t in contact with each other, so they used their own local methods. Usually, they were based on the Sun’s changing position in the sky (caused by the Earth turning).

Sun’s setting – bedtime!

MAKE A SHADOW CLOCK

This shadow clock works just like an ancient one.

Yo u will need –

A sunny day A flat outdoor space, such as a patio A pencil or chopstick A large piece of card A few pebbles Sticky tack or Plasticine A marker pen A clock or watch

What you do 1. Put your card on the ground and hold the corners down with pebbles.

2. Use Plasticine or sticky tack to stand the pencil or chopstick up in the middle.

3. Once an hour, draw a line on the card where the shadow is, and mark it with the time.

If it’s still sunny the next day, see if you can use your clock to tell the time!

time and Us

When you’re bored, or waiting for something to happen, time seems to tick by super-slowly…

A weird thing about time is how it can seem to stre-e-etch out or shrink in different situations!

Urgh, WHEN is the bus going to get here?!

But when you’re very busy or having a great time it seems to whizz by!

What?!! It can’t be that time already!

WHAT ’S HAPPENING?

Time isn’t really going faster or slower in these situations. Your perception of time (how it seems to you) can be different from what’s really happening.

When your brain is busy doing something interesting, it has more signals zooming around inside it. That makes it think time is going faster. When nothing much is happening, there are fewer signals, and that makes your brain think time is passing more slowly.

Your brain experiences time as going faster when you’re busy, and slower when you’ve got less to think about.

BODY CLOCKS

Your body has an internal ‘clock’ that makes it go through a pattern of changes roughly every 24 hours. This is called a circadian rhythm. At different times of day, hormones (body chemicals) make your body do different things.

Sleep hormones make you sleepy in the evening

MAKE A SAND TIMER A sand timer, or hourglass, is a device that has been used to measure the passing of time for thousands of years!

Yo u will need

wo small plastic bottles T Dry sand A screw Electrical tape A digital timer or smartphone

What you do

1. Ask an adult to help you poke a hole through the centre of one of the bottle lids, using the screw.

2. Screw the lid with the hole back onto the bottle.

3. Pour sand into the other bottle then tape it to the lid with the hole in to join the two bottles together, as shown.

4. Use a timer to measure how long it takes for the sand to fall into the other bottle. Adjust the amount of sand until it takes exactly two minutes.

Time goes more slowly when you travel on a fast jet plane.

Answer on page 34

Around the world, the Sun rises at different times – so we have different time zones. For example, when it’s 11 pm in the UK, it’s 7 am in Japan, and people are just waking up. If you travel to a different time zone, you can get jetlag – your body clock is stuck in your old time zone, so you might feel like sleeping in the day and being awake at night until your body gets used to the change.

Use your timer to test your perception of time! See how long two minutes feels like while you’re watching TV, then try it again while running on the spot! For more Vancouver is in a different time challenges, turn time zone to the UK so the time there is always eight to page 14.

Periodical Cicadas

This month, our vet Joe Inglis has put down his stethoscope and picked up his calendar as he tracks down some very strange insects that keep perfect time...

Periodical cicadas are insects that look like locusts and grasshoppers. There are around 3,000 species of cicadas found in the world, but just seven species are periodical cicadas, and they all live in the eastern parts of North America.

Time machines These cicadas are called ‘periodical’ because of their very strange ‘time-travelling’ life cycle.

For most of their lives – around 99.5% – they live as larval nymphs in the soil. But one day, after an exact period of time (either 13 or 17 years), millions of them emerge together from the ground as adults.

Larval lifestyle © Tony Quinn / Shutterstock.com

During their long years underground feeding on plant roots, the nymphs go through five different stages of development. When they reach the final stage, they start to tunnel up towards the surface where they wait, ready to emerge at exactly the right time.

Marvellous May metamorphosis When the soil temperature reaches exactly 17.9 °C, usually in April or May, the nymphs crawl out from their tunnels and undergo a final transformation into adult cicadas. They are about 2-3 cm long with wings and a long mouthpart called a proboscis.

12 whizzpopbang.com

Brood bonanza Not all periodical cicadas emerge in the same year. There are 15 known groups, called broods, which start and finish their lives in different years. In 2024, two broods will emerge – brood XIII is on a 17-year cycle, and brood XIX is on a 13-year cycle.

Worth the wait?

1.5 million

After waiting for 13 or 17 years to finally emerge from the soil and fly up into the sky, adult cicadas will only live for another few weeks. Their only goal is to mate with a partner to create the next generation of nymphs. Once this is done, their long lives are over and their offspring start their own wait underground.

The number of cicadas that emerge from each acre of land. In total, a brood of cicadas can include more than a trillion individual insects.

Yawn!

Prime time

Is it that time already?!

Why do periodical cicadas emerge every 13 or 17 years and not every five or ten? One answer is that 13 and 17 are prime numbers , which means that they can only be divided by themselves and one.

This means it is hard for animals that eat cicadas but have shorter life cycles to evolve so that they are always ready for the next brood to emerge.

Find these prime numbers in the grid. They might be written from left to right or downwards (not diagonally, backwards or upwards). Circle your answers and check them on page 34.

Test your time perception with these 60-second challenges!

Use a timer, stopwatch or one-minute sand timer for all of these games.

Slow race Choose a route to walk around your house or garden that takes about 15-30 seconds. Decide on your start and finish lines, and start the timer as you set off from the start. The aim of the game is to arrive at the finish line in exactly 60 seconds. On the way, meow like a cat, bark like a dog or make other animal noises (so you can't cheat by counting!).

Depending on what you’re doing, time can feel like it’s passing quicker or slower. When something scary happens, the nerve cells in your brain (called neurons) have to process lots of information very quickly and it feels like time slows down. Scientists tested people who were bungee jumping and found that although they were falling for only two and a half seconds, they thought they were falling for four seconds! This feeling that things are happening in slow motion might help us to react more quickly if we find ourselves in danger.

Have you ever tried to catch a fly? They react so quickly that it seems almost impossible!

Thatʼs because to them, time appears to pass more slowly so it looks like weʼre moving in slow motion.

Researchers tested more than 130 species of animals and found fast-moving ones – especially small animals, flying animals and top ocean predators – can process more frames per second than slowmoving animals.

Out of the animals tested, dragonflies see the fastest, detecting 300 flashes per second, while the crown-ofthorns starfish was the slowest, noticing only three flashes every four seconds!

Scientists worked this out using flickering lights. Humans can detect light flickers at up to 65 flashes per second. If the light flashes any faster than that, we don’t notice the flicker and just see a continuous glow.

Barmy balloons

Drum fun Hit a drum exactly 100 times in a minute!

If you don’t have a drum, use a wooden spoon and a cardboard box. Count to 100 out loud as you hit the drum and stop the timer when you reach 100.

How close did you get to 60 seconds?

Blow up three balloons.

When the timer starts, throw them up and then see if you can keep all three balloons in the air for one minute. Shout ‘stop’ when you think 60 seconds have passed!

Beat it!

Listen to some music with a fast beat and shout ‘stop’ when you think one minute has passed. Now listen to a slow piece of music and do the same. Was there any difference in how long it took before you thought a minute had passed?

Chatty challenge Talk about what you did yesterday for exactly one minute without stopping. Shout ‘stop’ when you think a minute has passed.

You could play again while making up a story or singing a song!

If it takes 20 minutes for the sand to run from one chamber of this sand timer to the other, how many times will you have to turn it over to time two hours?

TEMPLATE 2

Leap years A year is how long it takes for the Earth to complete one full orbit around the Sun. We think of a year as being 365 days but in fact, one full orbit is 365 days and six hours (almost!). The extra hours don’t fit neatly into our calendar so we ignore them for three years. Every fourth year, the extra hours have added up into a full day which we put into the calendar in February, making the year 366 days long.

Every year that is divisible by four has the extra leap day, including this year! 2024 ÷ 4 = 506

But remember we said that extra bit of day was only ‘almost’ six hours? By adding an extra day every four years we’re actually over-correcting and adding slightly too much. So we wait until those tiny bits of over-correction add up to a whole day too much and then we skip putting in a leap day – this happens once every 100 years and it’s always in a century year – 1700, 1800, 1900…

But wait, why was there still a leap day in the year 2000?! It’s because losing that leap day every 100 years is also a very tiny over-correction, so once every 400 years you don’t take it out after all! This happens every time the year is divisible by 400, so the next time it happens will be the year 2400.

Every four years, we add in an extra day at the end of February to account for the extra ¼ days. If we didn’t do this, the start date of seasons would gradually shift. After hundreds of years, summer could start in November!

How to play

Place the lily pads on a large table or on the floor. Take it in turns to make your frog leap onto the lily pads in the correct order. Place your finger on the frog’s body between its back legs, then press down quickly towards the floor to make it jump. Each player gets three tries to make their frog jump onto the lily pad, then it’s the next player’s turn. The first person to complete the course is the winner!

Astrophysics is about looking at the universe to understand how it works.

However, I remember looking up at the night sky and being fascinated by the stars as a child.

I was very curious and asked lots of questions.

Things changed when I went to secondary school and I started learning about the sciences as separate subjects. I found I really loved physics and chemistry.

Scientists think of things in space like stars, planets and comets as laboratories for testing our understanding of how the universe works.

Gravity slows down time, which means that the clocks on the ISS run faster than the clocks on Earth (because Earth’s gravity up in space is a lot weaker). This also means that your head is ageing a tiny bit quicker than your feet (because Earth’s gravity is strongest at your feet)! Astronauts on the ISS are ageing quicker up there than when they are on Earth. These are real examples of time travel! So, you might be able to travel to the future, but travelling back in time looks a lot more complicated. Be warned: before you embark on any time travel adventures, it might be a one-way trip!

Cuckoo clocks

HOW STUFF

WORKS

For nearly 300 years, skilled craftspeople in Germany’s Black Forest have been making these very special clocks. They come in many shapes and sizes, but they all feature a carved cuckoo bird that pops out of the clock face every hour.

Here’s how these bird-brained clocks work…

1

Cuckoo clocks are usually handmade from wood in the shape of an old-fashioned German house with a sloping roof and a little door near the top.

2 3

On the front is the clock face, which shows the time with an hour and a minute hand.

Behind the clock face is the clock mechanism which has lots of tiny gears that drive the hour and minute hands on the front.

4

The mechanism is driven by a pendulum, which is a rod hanging below the clock that swings from side to side. The pendulum is carefully designed so that each swing takes exactly one second.

5 24 whizzpopbang.com

Near the bottom of the pendulum rod is a weight called the pendulum bob (traditionally shaped like a maple leaf).

This helps to keep the pendulum swinging for a long time.

10

9

8

Some clocks also have a third chain and weight which powers a little music mechanism that plays a tune as the cuckoo emerges, just like a tiny music box.

Another weighted chain provides the energy for a little wooden cuckoo to pop out of the door above the clock face every hour. As well as powering the movement of the door and the cuckoo, it also operates a pair of tiny bellows that make the distinctive ‘cu-ckoo’ sound as the doors open.

7

6

To keep a cuckoo clock running, the weights need to be pulled back up (by winding the clock) either every day or every eight days, depending on the clock.

One of the chains drives the pendulum via a special gear that allows the chain to move a tiny amount every time the pendulum swings past, transferring energy from the weighted chain to the swinging pendulum and keeping it running.

Also hanging below the clock are several chains with weights shaped like pinecones at the ends. These weights power the clock as gravity slowly pulls them down towards the ground.

A pendulum is constantly switching between two types of energy – potential (stored) energy, when the bob is at its highest point, and kinetic (movement) energy, as it swings down.

If there was no friction, the pendulum would keep on swinging forever, but because friction gradually slows it down, it needs to use the potential energy stored in the weights.

A playground swing works like a pendulum too! The time it takes a pendulum to swing back to its original position is called the period. Use a timer to measure how long it takes to do 10 swings (starting and finishing at the same point), then divide the number by 10 to get the average period of this pendulum. Do you think someone heavier than you would get the same results? Why not test your hypothesis by doing the experiment again with an adult on the swing. If you’re able to adjust the length of the swing’s ropes or chains, you could investigate whether that changes the pendulum’s period.

Dear Y, Why do creatures have scientific names?

Lexi, aged 9

CURIoUS K I DS

Have you heard of a slater, Lexi? What about a cheese-log, chucky pig, granny grey or billy baker?

These are just some of over 300 British names for a woodlouse! We have 35 different species (types) of woodlouse in the UK, and there are about 4,000 worldwide – just imagine how many local names that makes! Having one worldwide scientific name for a woodlouse species saves a lot of confusion.

The UK’s most common species is Oniscus asellus. (say on-iz-cuss ay-sell-us). The genus Oniscus is a group of woodlice which do not roll into a ball, and the species name asellus means small donkey!

Look what Alastair found!

It looks like a stinkh or fungus. They smell n like rotting flesh and at tract insects – you can se e some flies on it in Alastair’s brillian t photo.

Metals are made from tiny particles called atoms.

Each atom has a nucleus surrounded by spinning electrons. These orbit around the outside – a bit like planets around the Sun. As an electron moves, it makes a weak magnetic field. In some metal atoms, like iron, nickel and cobalt, you can make the spins of the electrons line up. That makes the weak magnetic fields join together to make a stronger one. Add lots together and you have a magnet! In non-magnetic metals, the spins don’t line up, so the weak magnetic fields cancel each other out.

Dominic, aged 7, on a mushroom hunt.

You can make a metal magnetic yourself! Take an iron nail and stroke a bar magnet along its length, in one direction only, 20-30 times. This forces the magnetic fields to line up. Now see if you can use your magnetic nail to pick up some paper clips!

Write a report or a review to earn your Science Reporter badge.

Many animals yawn, but only highly social animals, like chimps and lions, can also ‘catch’ yawns. You might even start yawning as you read this, Violet! We used to think yawning increased blood oxygenation, but this is not true.

Now, many scientists think it helps to wake you up when you’re sleepy. Contagious yawning may have evolved to coordinate group behaviour. A yawning, sleepy person is not properly on the lookout for danger, but as their yawn spreads through the group, someone less sleepy will notice they are yawning and become more alert – maybe saving the group. Some people are more susceptible to contagious yawning – try it on your friends!

Page 11 – True/Untrue

Page 15 – Sand timer puzzle

TRUE: Using very accurate atomic clocks, scientists have proved Einstein’s prediction that clocks run more slowly when they’re travelling faster. This happens because of the way that space and time are connected.

There are 60 minutes in an hour and 120 minutes in two hours, so you would have to turn it over five times. The top chamber is already full of sand so you would turn it after 20 mins, then after 40 mins, 60 mins, 80 mins and 100 mins.

When all the sand has run into the bottom chamber for the last time, you have reached 120 minutes.

View through time This colourful image taken by the James Webb Space Telescope shows an area of the Eagle Nebula known as The Pillars of Creation. This region of gas and dust is constantly changing.

Dense clumps form within the pillars and start to collapse under their own gravity, then they heat up and begin shining brightly as brand new stars.

The Pillars of Creation are 6,500 light-years away from Earth, which means it takes 6,500 years for the light to reach us. So when we look at this beautiful image, we are looking thousands of years back in time!
