Why do birds move in unison?

By EmoCat

Animals – be they honeybees, fish, ants or birds – often move together and seem to make decisions at a moment’s notice, a phenomenon that has puzzled many researchers. According to lifeslittlemysteries.com, V-shaped formations help birds conserve energy, since each bird flies slightly ahead of the other, so there is less wind resistance. To keep things fair, birds take turns being in the front, with each bird moving to the back when it gets tired. This V-formation also enhances communication and coordination within the flock, allowing birds to improve orientation and follow their route more directly. So, birds of a feather really do flock and fly together! for us like Wanna write .hip2b2.com w w w it EmoCat? H e THINK.crew. and join th

smart news How well do you know your hand?

Fixing the world one piece of Lego at a time

So you know your schoolwork like the back of your hand, do you? Well, according to new research, that just means you know where it is, but you’re not so hot on the details. In a recent study, volunteers were asked to hide their hands under a board and then use a stick to point to their fingertips and knuckles. Weirdly, the volunteers thought their fingers were 5–35% shorter than they were, while they thought their hands were 6–7% wider. What’s up with that? Well, researchers think this occurs because our mind sees areas that are more sensitive to touch (like your palms and fingertips) as bigger than less sensitive areas (like the middle of each finger). Crazy!

ANTS VERSUS ELEPHANTS No gravity, no power You have to be really tough if you want to get sent into outer space. But it seems that astronauts aren’t quite so tough when they get back to planet Earth. See, living in space isn’t easy – new research shows that astronauts aboard the International Space Station for 180 days lose up to 40% of their strength. That’s like a 30- to 50-yearold’s muscles shrinking to those of an 80-year-old. Eish.

Elephants have been known to uproot trees or strip them bare for a quick meal. So Kenya’s whistling thorn acacia trees have the ideal defence: ants. These trees provide ants with homes and food. In return, the ants attack any creature that threatens their house. But can teeny ants really help? Yes, say Kenyan researchers, who tested the ants’ protective power by driving them out of some of their trees. A year later, all the antless trees had much more damage than ant-filled ones. So how do the bugs fight such huge beasts? They bite and sting the thinnest layers of skin, the eyes and inside the trunks. The giants can’t fight the tiny ants, so they hit the road ASAP. Just proves you don’t have to be big to be great.

Designer Ashley Legg’s Smart Fridge concept could save you, thanks to three simple functions (in addition to, you know, refrigerating stuff). Firstly, there’s a touch-screen panel on the door that lets you record what you put in and take out, so you’ll always know what’s in there. Secondly, the fridge can use this info to give you recipe ideas – so unless you have some really weird stuff in there, you’re bound to get a meal. Thirdly, it can deliver step-by-step instructions to guide you through the cooking process. Jamie Oliver, eat your heart out.

a cellphone’s touch screen? Buttons are so last century … these days cellphones need only a screen, and all you need to do is touch it and it’ll do whatever you want (except perhaps give you the exam answers). Most touch-screen cellphones use one of two types of technology: resistive, which means the screen picks up the pressure of your finger, or capacitive, which means the screen has an electrical field on its surface, and this gets changed when someone touches it. We decided to deconstruct the Samsung Star, to see how its touch screen works. This cellphone uses a simple but

smart resistive system. Beneath the cellphone’s protective PET film (1), there is a conductive layer (2)and a resistive layer (3), separated by an air gap (4). This air gap is held open by microdot spacers (5). When you touch the screen, the surface is pressed down and the conductive and resistive layers touch each other, closing an electrical circuit. The cellphone’s computer can tell exactly where the two layers touched. Then all it needs to do is carry out whatever function was displayed on the screen at that position.

Senses ways dolphins make sense of their world

• Super-sight

1

Dolphins’ eyes can see extremely well, whether they’re cruising through dark water or coming up to the bright surface for air. Here’s how they work: • Their eyes don’t have to work together. Each one can move upwards and sideways on its own. • A special, curved lens and cornea (which is a thin layer behind the lens) make sure that light rays are bent just right for sharp focus when dolphins jump into the air. • In dim light, a layer of reflective cells, almost like a mirror, behind the retina reflects scattered light back onto the retina a second time.

Humans can’t hear anything above 20 kilohertz (kHz) –hit www.hip2b2.com to find out if you can hear this high sound – but dolphins can hear crazily high-pitched sounds (anything between 1 kHz and 150 kHz). But hang on, where are their ears? Well, they don’t have external ones like ours. Instead, they have fatty tissue in their lower jaw, which directs sound waves to the middle and inner ear. From there, the nerve that carries the signal to the brain is almost twice as thick as ours, which helps get messages processed in a flash.

Although we don’t know much about dolphins’ sense of taste, we know they have taste buds on their tongues, just like humans. They can pick out sweet, sour, bitter and, yup, salty.

Dolphins have gazillions of touch receptors in their skin and are especially sensitive to water movements close to their heads, flippers and genitals. Dolphin calves (babies) also have whisker-like hairs around their mouths, which help with touch when they’re young. They lose these whiskers after nursing.

Dolphins can also ‘see’ with their ears. They make high-pitched click sounds, which bounce off any object that’s close to them and come back to their ears as an echo. The echoes are used to create a sound map of their surroundings. This is called echolocation – Turn the page to see how it works …

Echolo-what?!

Have you heard about the WOWee? It’s a portable speaker with a difference – the perfect prize for music lovers! Hit www.hip2b2.com to find out how you can win one!

So how does echolocation work? Well, imagine you’re standing at the edge of a canyon. You shout ‘Hello!’ and after a short while you hear an echo. The sound has bounced off the other edge of the canyon and back into your ears. This is exactly how animals like dolphins and bats find their way in the dark. They send out high-pitched squeaks or clicks and if there’s something in their way, the sound will bounce off the object and return to the animals’ ears. Because they know how fast a sound wave travels – in water or in the air – they can work out how far away the object is just by measuring how long it took to hear the echo. Their brain just does this stuff automatically – they don’t even need to write the calculations down!

But what about direction? These animals can also use time differences to tell the direction an echo is coming from: if both ears hear the echo at the same time, the object is straight ahead; if the echo reaches the left ear first, it’s on the left; if it reaches the right ear first, it’s on the right. Sneaky … High frequency sounds work best for echolocation. The higher the sound, the shorter its wavelength. And the shorter the wavelength, the smaller the object that can be detected – which is really handy when you’re looking for a tiny fish or mosquito to munch.

After feasting on insects all night, a bat flies back into its cave, with the wall straight ahead. The bat sends out a squeak and hears the echo after 55 milliseconds. How far is it from the cave wall? Remember that sound travels at 343 m/s in air.

The nose that knows

Scientists think dogs are at least 100 000 times better at sniffing out things than we are. They have almost 200 million scent receptors, while we’ve only got five million. But the area in their brains dedicated to smell analysis is also almost 40 times bigger than the area in our brains. Spot’s wet nose is key to his sense of smell. When he sniffs, any scent molecules in the air attach to his snout and dissolve in the mucus lining his nose. This helps him smell stuff at much lower concentrations than we can. Dogs need only five footsteps to follow a human odour (smell) trail. Scientists asked someone to walk forward on a line of loose carpet squares, placing only one footstep per square. Dogs brought in to the trail at right angles could correctly sniff out its direction when there were five squares or more. The scientists then removed some of the squares. With only three squares left, the dogs couldn’t pick up the scent.

Good vibrations With such huge ears, you’d think elephants wouldn’t need help hearing stuff. But scientists recently showed that these creatures use their feet to pick up sounds of 20 Hz or lower – which we can barely hear. Elephants make rumbling sounds of very low frequencies when they’re alarmed. The vibrations travel along the ground and warn others of the danger. Scientists think elephants have sensitive nerve endings in their feet to pick up these vibrations.

14

There’s good reason why someone with sharp eyes is said to have eagle eyes. Because eagles really do have sharp eyes. Some eagles can see up to four times better than humans, which means that what we can see at five metres, eagles can see at 20 metres. Of course it helps to have almost five times as many lightsensitive cells in the eye as we do. Eagles also have two areas for sharp focus in each eye, while humans have only one. And as if that’s not enough, eagles’ eyes can pick out five basic colours, while our eyes can only see three – red, green and blue (the rest are just a combination of these A supertaster is someone who three). finds tastes especially strong.

Are you a supertaster?

Research shows that roughly one in four people is a supertaster and these people often don’t like food that’s too bitter (like coffee), too spicy (like chilli) or too extreme in any way. It all depends on the number of taste buds you have on your tongue … do this test to find out if you fit the profile.

Place the magnifying glass over your tongue and count the pink spots inside the ring (these are your taste buds, which don’t absorb the dye). If you have over 30, you’re probably a supertaster; if you have 15 to 30, you’re likely a ‘normal’ taster, and if you have fewer than 15, chances are you’re a nontaster, which just means that you prefer stronger flavours (like very salty or spicy foods).

Eagle eyes


Your friends love toasted sandwiches. They eat them in the quad where you practise. When you inhale, the cheeseand-tomato molecules come in with the air and dissolve in the watery mucus lining your nose. At the roof of your nose, a patch of receptor cells pick up the scent and send signals to your brain. Mmmmm. Smells good!

Smells good

You need to keep your eyes wide open if you want to conquer the ramps. But how does sight work? Well, imagine you’re approaching a ramp. Light reflects off it and hits a layer at the back of your eye, called the retina. The retina contains thousands of cells and inside these cells are light-sensitive pigments (dyes). When light hits the dyes, their structure changes, causing a signal to zip all the way along the optic nerve to your brain. The brain combines all the signals and tells you to prepare for take-off!

Chocolate bars don’t grow on trees. But the cocoa beans they’re made of do. Cocoa trees grow in hot, dry climates and are known to botanists and people who speak Latin as Theobroma cacao (‘Theobroma’ is Latin for ‘food of the gods’ … and we totally agree). Each tree produces big, dark pods that are about as long as your school ruler, and inside them you’ll find 20 to 60 seeds, or beans. Each bean contains a fat called cocoa butter, and when you crack a pod open, the precious seeds are clumped together to look like a white mielie.

Is chocolate really bad for you?

FAST FACT

About two thirds of the world’s cocoa is made in West Africa, with about 43% coming from Cote d’Ivoire.

Not necessarily. But don’t raid the chocolate tin just yet. According to scientific research, only dark chocolate has been shown to have health benefits, and even then, you shouldn’t have too much. Dark chocolate contains high levels of cocoa, and the more cocoa there is in a slab, the more antioxidants it contains. These chemicals help to keep your heart healthy, giving you a very good reason to treat yourself every now and then. Of course, the stuff is still high in fat, so don’t overdo it, okay?

the tasty truth

FACT FILE: Food tastes boring without your sense of smell. Don’t believe us? Block your nose and try to taste which jellybean flavour is


y r t a n e m u The yummy history

People in Mesoamerica (the area that stretches from Mexico to the Amazon jungles) have been making chocolate for centuries. The ancient Aztecs who lived there used to make a cocoa drink called xocolatl, which meant ‘bitter water’ in their Nahuatl language. When the Spanish conquered the Aztec lands in the 1500s, they brought cocoa beans back to Europe … and the drink became hugely popular there.

In 1828, a Dutch chemist and his son found a way to extract cocoa butter from cocoa beans. By removing the cocoa butter, the cocoa powder became much less bitter and more awesome to drink. About 20 years later, an English company thought of mixing the cocoa butter back into the cocoa powder, adding sugar and creating a paste. This paste became the world’s first dark chocolate bar. Thirty years later, a Swiss guy named Daniel Peters (or a guy called Henri Nestlé,

depending which books you read) added milk powder to make the first milk chocolate. Fast-forward another 100 years or so and you’ll have reached the time when Bar One was born. Bet you didn’t know where it was created, though … right here in South Africa! Do you know where

HOW CHOCOLATE IS MADE The secret to making great chocolate lies in those little beans … and in what gets done with them. Let’s follow the process, all the way from the cocoa trees in West Africa to the slab you’ve got stashed in your bag.

Cocoa pods are cut down from the tree with a knife or by prodding the really ripe ones with a stick until they fall off. The pods are cut open and the beans and their surrounding pulp are taken out and put in piles to ferment. Then the beans are left in the sun for about a week to dry.

which.

The dried beans are cleaned and roasted. Then the shells are removed and the nib (that’s the part inside the cocoa bean) is taken out and ground down into a powder.

The cocoa powder is liquefied to create cocoa mass or cocoa liquor (which isn’t alcoholic). The cocoa butter is then extracted from the cocoa mass.

This is the fun part. Depending on what type of chocolate is required, the chocolate maker has three different options: For DARK CHOCOLATE (the superbitter stuff), you mix sugar, cocoa butter and cocoa powder. For MILK CHOCOLATE (the normal, lightbrown chocolate), you mix sugar, cocoa butter, cocoa powder, milk powder and vanilla. For WHITE CHOCOLATE you leave out the cocoa powder, and simply mix sugar, cocoa butter, milk powder and vanilla.

your taste buds for bitter foods are? Hit www.hip2b2. com to find out why things taste different according to where they touch your tongue! Now take a look at the wrapping on the chocolate bar in your school bag – any ingredients other than the ones we’ve listed here (like vegetable fat, emulsifiers or flavourants) are really just there to bulk the stuff up or change the flavour or texture.

How many possible positions can the corner pieces of a Rubik’s Cube be in? Well, because it’s a cube, it has eight corners. The first corner can take any of the eight corner pieces, but after you place one of those, the second corner can only have seven, and so on until only one piece is left for the eighth corner. So the answer is 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40 320.

I always knew about ‘Blue Monday’ and ‘Black Friday’ … Then HIP2B2 introduced ‘Blind Sunday’ to my vocabulary list. Here’s what happened. 09:00 I take a last (‘illegal’) peek at my surroundings and put my eye pads on. Suddenly, I’m left with only the natural sensitivity on! to light our eyes have when go rs ke in bl The they’re closed. I can easily move around my room, as this was the last room I saw. The rest of the house is left to visual memory. Uh oh. 10:00 I meant to choose what I wanted to wear before I put the blindfold on, but I forgot. I swing my cupboard doors open and stand there, waiting for that ‘Aha!’ moment to arrive. It doesn’t. So I call for help and rely on my friend to make me look presentable.

Science to the re scue

If your sight’s not so great, you can get glasses, contact len ses or even eye-laser surgery to help you to see more clearly. If you’re totally blind , technology is available to help yo u too. One solution was created right here in SA by Louis van Biljon , a 2008 HIP2B2 Bran d Ambassador. Louis invented ‘Eyes for th e Blind’, an infrared box that gets strapped to a blind person’s body and warns him or he r when an obstacle’s ahead. Check it out at www.hip2b2.com .

11:00 I fumble around in search of breakfast. In the kitchen, I realise two things: 1. Although I know where the food is, I can’t tell the difference between products that are packaged using similar materials (eg, cardboard boxes). 2. I can’t tell how much food I want. Once again, I must ask other people. 12:00 Just survived a shopping trip. Here is my ‘Official Guide to Sightless Shopping’: First: pay attention to the ‘feeling’ of your surroundings (eg, soft, varying textures = clothing store). Second: the atmosphere of the store gives a clue as to what it is (vibrant atmosphere, people bustling past with trolleys = grocery store). Third: smells can help you navigate a store (while walking in a pharmacy, a sweet scent assaulted my nose and I knew immediately I was in the fragrance aisle).

13:00 Lunch! I’m led to the table and given a ‘guided tour’ of my place setting. Amazingly, I manage to polish off a plate of food and dessert without causing too much damage. 15:00 I can’t read a word or operate devices. I think I can find my way around the house until I walk (face first) into a wall. 16:00 My eye pads come off and I greet the world with a heart full of appreciation for sight. What I thought Although this has taught me to savour food and to use creativity to link images to sounds, I’m relieved to regain my sight. I’m also pleased to gain an understanding of the struggles blind people face.

It may look like ice cream and it may smell like ice cream but it doesn’t taste like ice cream. Why? Because these cute little tubs contain ice cream-flavoured lip balm. Scoop a little onto your lips to keep them soft and supercomfy.*

finally the trophy was retrieved by a dog.

Smelly candles Check out the noughts and crosses and squiggles on these crazy floating candles. Made in SA and decorated in lots of bright colours, they’ll fill your room with a pretty glow and the sweet scent of vanilla. Mmmmmm.

WAKE UP! This cute mini-alarm clock comes in a range of crazy colours … but besides looking bright next to your bedside lamp, its function is to ring your brains out so you don’t wake up late for school.*

Seeing in pink Not only do these funky sunglasses have UV protection to keep your eyes safe from the sun, but they also have raindrop disco balls that look like bling earrings for those party nights with friends. How’s that for divalicious?*

FACT FILE: A Russian billionaire paid $1 000 000 to appear in the music video to Lady Gaga’s song, Alejandro. He’s the stern-looking I actually did audition for Idols. Long ago. I was forced into it. I was going to sing ‘Stuck In The Middle’ by Stealers Wheel, but the judges thought it was too old and told me to ‘Get with it’.

If you auditioned for Idols, what song would you sing?

This is our first album as Evolver One (we released two albums as Evolver). We drew inspiration from two bands we’ve been listening to a lot: The Killers and Muse. The sound is fresh – we’ve mixed electronic synth sounds with rock guitars.

There’s a whole bunch, but two ever eaten? spring to mind: Wresterlish A dish I tried at China City in – they mixed our album Jo’burg. It was a biltong-type and they’re really thing mixed with chicken To win a copy of cool – and Crash Car beaks and tongues. Evolver One’s new CD, Burn – I love the Disgusting. It smelt like SMS ‘HIP’ followed by way they write and an animal that had died ‘Evolver’ to 32976. R1/SMS. Terms and construct songs. a million years ago.

‘Imagine’ by John Lennon. I love the way it’s so stripped down – no drums, just Uncle Johnny on the piano. And, of course, the meaning is beautiful …

So someone suggested I sing Blue’s version of ‘Sorry Seems To Be The Hardest Word’. The audition was horrible – I was exhausted, I’d been waiting all day, I hadn’t eaten and was about to pass out from hunger.

What song do you wish you’d written?

We chatted to lead singer Pete Pote about the band’s new album, auditioning for Idols and the weirdest thing he’s ever eaten.

probably the most fun car game I have ever played. Fil led with fast-paced effects and mind-blowing cars, it’s pretty addictive and quite challenging. You tak e the role of an expe rienced stunt driver who is competi ng in a reality show wh ere drivers go up against one an other and race throu gh an explosive set. Extremely excit ing, whether you’re into cars or not; this game is awesom e and gets an A+ fro m me!!

Complete this grid using the numbers 1 to 9. The small number in the top left corner of each coloured area is the sum of the numbers in that area, and the numbers on the sides of the grid are the sum totals for each row and column. The numbers in each row, column and shaded area must be unique (in other words, 3 + 4 + 1 + 3 can’t be a solution, as 3 is used twice).
