It’s genetic, isn’t it?

Genetics is the study of how genes are inherited in a population. A scientist interested in genetics is a geneticist. If something is genetic, that means it is passed to you by your Mum and Dad. You inherit genes from your parents.
Genes control most aspects of human life, from eye colour to how fast you can run. There are some fun ways to demonstrate genetics in your own family.

Take tongue rolling. The ability to roll your tongue is what we call a dominant trait. If you have the gene for tongue rolling you will be able to roll your tongue.

What is Juno?

There has been a lot of excitement about the Juno probe this week, but what is it and what is its mission?

What is Juno?

Juno is a spacecraft designed and operated by NASA, the US space agency. It was launched from Cape Canaveral on the 5th August 2011 and has taken almost 5 years to travel the 716 million kilometres to Jupiter, the largest planet in our solar system. Juno is 3.5 metres in height, and when its solar arrays are extended it’s more than 20 metres across. These arrays are covered in more than 18,500 solar cells, which allows Juno to operate even when it’s at such a great distance from the Sun.

Why is it called Juno?

In Roman mythology Juno was the Queen of the gods. She was married to the king, Jupiter, who wasn’t always well-behaved. Juno had to peer through the clouds to discover what he was up to; the spacecraft is called Juno because it will be looking beneath the clouds that cover the surface of the planet Jupiter.

Aboard the Juno craft are 3 models of Lego minifigures: Jupiter, Juno and Galileo, who discovered in 1610 that Jupiter had moons.

What is it looking for?

Jupiter is enormous; it’s two and a half times larger than all the other planets in our solar system combined. It’s made entirely of gases and is believed to have no solid surface. The planet rotates at an immense speed, completing one rotation every ten hours, and telescopes have shown us that it has a cloudy atmosphere with colourful spots and stripes. The largest of these, known as the Great Red Spot, is a storm that is several times the size of Earth and has been raging for more than 300 years.

This mission is the first time that humans will be able to glimpse what lies beneath Jupiter’s cloudy atmosphere. The main objective is to understand how the planet formed and evolved, which will give us more information about the formation of gas giants as well as the rest of the solar system. Juno will also measure the quantities of water and ammonia within the atmosphere, examine the magnetic field that surrounds the planet, observe any polar auroras and measure the gravity to see whether a solid core may exist after all.

For more information about the Juno mission you can watch this video from Nasa, and have a look at the Juno mission webpage.

Life in an English Village

life in an english village

When we think of a country, we often think of a stereotype – an oversimplified image or idea. These are some country stereotypes – can you guess which countries we are meaning here?

Stereotype 2

Stereotype 1

Sometimes a stereotype is used in a negative way, but often we use them because they are the only things we know about the country we are talking about. They are often based on a truth about the country and can be a part of life in that country.
An English Village is today’s topic. When you search for an image of ‘English Village’ you might find something like this

English Village

You might think that living in an English village is all thatched cottages, red telephone boxes, and Sunday afternoon cricket. That is certainly the stereotype!
If you live in a city, you might also think that living in a village like this would be boring, that there might not be much to do, but you would be surprised how busy life in a small community can be.
We asked our contributor Liz to tell us what it is really like to live in a small English village not far from the capital city, London.

Adventure in Uganda

On my second day in Uganda, we went white water rafting on the Nile, near a town called Jinja. The rapids are just Screenshot 2013-10-14 at 10.50.13down river from Lake Victoria, which is where the Nile starts.

The rapids are caused by the force of the water as it crashes over rocks and around islands in the river. There used to be more rapids there, and the famous Bujugali Falls. However, a couple of years ago a dam was built across the river, which has made part of it more like a lake and has increased the water levels, wiping out lots of the rapids, including Bujugali. However, below the dam, the rapids are still just as scary! The rapids are a favourite for rafters and kayakers all over the world.
