SCIENCE NEWS – Discovery of An Underground Ocean

Earth’s Underground Ocean

In 1864 the French author, Jules Verne, published his novel “Journey To The Interior of the Earth”. In this book 3 men explore volcanic tunnels that lead miles beneath the Earth’s surface, and have a number of strange encounters along the way. One of these is the discovery of a massive ocean, deep underground. Now, 150 years later, it seems that Monsieur Verne’s imagination may have been more accurate than he knew.

An enormous reservoir of water, roughly 3 times bigger than all of the Earth’s oceans put together, has been detected 400 miles below the surface. The water is trapped inside a layer of blue rock called ringwoodite, in the layer of hot rock between the Earth’s core and its surface) that is known as the mantle.

JUMP! Around the World – Ayşe in Turkey

Have you ever wanted to know what it is like to grow up in another country?

We continue our Jump! Mag tour of the world in Turkey, where seven-year-old Ayşe lives.

Hello Ayşe, How do I say hello in Turkish?

Merhaba Annie!

What are your favourite subjects at school?

That’s hard… I think most of all I like learning Turkish language and…….music.

What kind of music do you like listening to?

I like to dance to pop music like Rhianna and Adele but I like Turkish music too, I like a rock band called Duman.

What games do you like to play with your friends?

Mostly street games like Tag and hide & seek, it’s fun to chase each other around.

What do you like most about being a girl?

…….I think maybe because…you can have a baby… Also at school at playtime, the boys are always chasing each other and fighting and being a bit rough, and they can be like that with each other but not with us, they can’t be so rough with us. I like wearing dresses also and dressing up!

What are your favourite words in your language?

I love you…….mum.

If you could choose any country in the world to visit, which would it be and why?

I want to go to America, to visit my Aunt in San Fransisco, I want to swim in the sea in Mexico because my Mum has told me all about it. I’d also like to go to Africa, to visit the different native tribes that live there.

How would you describe your village to someone who wanted to visit here?

I live in a fishing village, it is very sunny, there’s no snow here! We have the sea, which I like to go swimming in and I like to go walking up around the mountain near the sea which is beautiful.

Here is some more information about Turkey

View Larger Map

Turkey is a large peninsula that bridges the continents of Europe and Asia. Turkey is surrounded on three sides by the Black Sea, the Mediterranean Sea, and the Aegean Sea. Istanbul, the largest city in Turkey, is built on land in the Bosporus seaway. The city is partly in Europe and partly in Asia. Turkey is larger than the state of Texas.

My Favourite (Favorite) Book

Writer Susannah Leigh was born in Canada and moved to UK when she was eight years old. Jump! asked her about her favourite children’s book.

One of the nicest things about being an author (apart from being able to go to work in your pyjamas) is being invited to talk about books in schools. I love chatting to enthusiastic pupils about all things bookish. Usually the questions I am asked are ones I can answer easily.

‘How long does it take you write a book?’

‘Where do you get your ideas from?’

‘When did you write your first book?’

But at a school last week a student asked: ‘What is your favourite book?’

Now that’s a tough one.

I’ve read so many good books, how could I possibly choose my favourite?

And what if I haven’t read my favourite book yet? Indeed, what if it hasn’t even been written?

A Trip to Mars!

Imagine being able to catch a flight to Mars as easily as we travel to another country – that was the idea behind the Trip To Mars session I attended at the Cheltenham Science Festival. It was conducted by Dr Suze Kundu and Dr Simon Foster and presented as a pre-flight safety briefing, with both of them dressed as pilots! There were a lot of humorous moments and sci-fi references but also some great science.

Suze and Simon suggested that in the future, flights to Mars could be far quicker than they are now, and explored how some of the bigger problems could be overcome. For example, the Sun’s magnetic field deflects a significant proportion of the cosmic radiation that could be harmful to humans on Earth; as spaceships travel further away from the Earth and Sun they will have less protection because the magnetic field weakens. To combat this it’s possible that spaceships will contain or be covered with large and powerful magnets, to produce the same deflective effect. This would have the added advantage of also deflecting radiation from solar flares.

Spaceships journeying to Mars would travel at such speed that even tiny fragments of rock and dust could be damaging to the hull. To combat this, and also the heat generated when the spaceship passes through an atmosphere, Suze and Simon discussed the possibility of spaceships being coated in aerogel. This amazing material is a solid formed from silicone dioxide but is 98% air; this means that it is extremely light but also strong. Its melting point is 1,200°C (equivalent to asbestos) and it is a wonderful insulator. Because it consists of large pockets of air between thin layers of silicone dioxide, any dust or rock fragments that hit it would be slowed and stopped before they could penetrate the aerogel completely.

Suze and Simon also discussed the possibilities and problems with cryostasis. Theoretically this is when a person’s body is cooled to temperatures so low that they enter hibernation, ideal for long journeys through space. Unfortunately our technology isn’t advanced enough to do this at the moment; any attempt would result in the cells rupturing and the person dying. But in the future it will be possible, perhaps after the person’s DNA has been altered slightly so that they can produce antifreeze proteins like some species of wasps and turtles.

What is The Point in Learning Maths?

Have you ever sat in a Maths class wondering when you will ever need to do long division without a calculator? Or silently cursed your Geography teacher while learning about the formation of oxbow lakes? And History? That’s all in the past and irrelevant, isn’t it?

In this series of articles, we will look at some of the subjects we learn at school, and try and answer the question: What’s the point in learning maths?

Let’s start with Maths. It is a fact of life that while some people are good at Maths, for others it is a daily trial. It is, however, along with English and the sciences the subject considered to be the most important. Why? Of course, we all know that it is important to be able to count, and do simple sums, but when, in real life, do we actually use it?
