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.

Drama Clubs for Kids – Written by You

Hi! My name is Cait, I’m 14 years old and I live in the North-East of England. No matter where you live in the world, there is a good chance there are some drama clubs for kids in your area. Drama is one of my favourite hobbies, and I thought by answering some questions it may make you think about starting drama!

Do you have to know what you are doing?

No! When I first started doing drama I had absolutely no idea how to act, and that was okay. I went into this small drama club and had no idea what I was doing. But over the time that I went there, I gained skills and I learnt how to act. Going into drama having no idea what you are doing can be good because it means you can learn so many new skills, which is great! Over time you can learn how to do other things as well such as singing or dancing!

Amazing Libraries and Bookstores Around the World

What do you like about going into a bookstore or library? Is it the smell of the books, or the sight of the different coloured spines, waiting to be pulled from the shelf, so that you can dive in?

We have compiled a list of some of the most amazing libraries and bookstores around the world. Some of them you may have heard of, others are less well-known, but all of them made us smile or gasp in wonder. Which one is your favourite, and which library or bookstore would you add to the list?

Real Gabinete Português de Leitura, Rio de Janeiro, Brazil

A building so remarkable that this one photo cannot hope to do it justice – more pictures here. This is the largest and most valuable collection of Portuguese literature outside of Portugal. The library was constructed between 1880 and 1887 – the facade was carved out of limestone in Lisbon, Portugal and transported by ship to Rio.

The Clifton suspension bridge: designed by a woman, built by Brunel

One of the best known landmarks in Bristol, UK, the Clifton suspension bridge first opened in 1864. It was built by the famous British engineer Isambard Kingdom Brunel, but it has recently become public knowledge that it was designed by a woman. Our science editor Sam Gouldson explains who she was and why her work isn’t more widely known.

Who really designed the bridge?

The Clifton suspension bridge was designed by a woman called Sarah Guppy. She was born Sarah Beach in 1770, but when she married her husband Samuel Guppy she took his name. She was one of the great British inventors of her time and the bridge isn’t the only thing she came up with.

What else did she design?

The invention that earned Sarah the most money was her device to prevent barnacles forming on the hulls of ships. Without barnacles the ships would be able to cut better through water and travel more quickly, and the Royal Navy paid her £40,000 for it. That may not sound like much for such a valuable design, but today it would be more than £2.3 million. Her other inventions included a kettle that not only boiled water for tea but could cook an egg and keep toast warm, a candle holder that could keep candles alight for longer and a way of treating boats so that they were more watertight. She also came up with the idea of planting willow and poplar trees on the embankments of new railways, to hold the earth together and prevent landslides.

Why isn’t she more famous?

Sarah lived during the Georgian and Victorian eras. In those times married women weren’t allowed to own property in their own name, and intellectual property such as Sarah’s inventions were no different. Her husband had to file the patents on her behalf, as the property of the Guppy family. The patent for her method of piling bridge foundations in order to create a new kind of bridge was filed in 1811, but she refused to charge others to use the idea because she felt it was for the benefit of the public. Thomas Telford, a civil engineer, used her design to build the Menai bridge in 1826, and when the competition to design the Clifton bridge was announced Sarah gave her work to Brunel. When she wrote to him to suggest the use of willow and poplar trees to reinforce railway embankments, she explained that she didn’t want the credit for her idea because she felt that women “must not be boastful”.

Do You Hate School Uniform? – Written By You

My name is Daisy, I’m eleven years old and although I am English, I have lived in Germany nearly all my life! I speak German and English and can read and write both too. I enjoy writing and listening to music and am the middle child of three. My mother is an author.

Does your school have a school uniform? Having to wear those scratchy skirts? Tight stockings? With our normal clothes, you can show what kind of person you are! You can send a message out to the world with how you dress, what makeup you were and how you have your hair done!

School uniforms are stopping all this. Not being allowed to choose what to wear seems so unfair! Wouldn’t it be fair if we could choose if we wanted uniforms or not? People are debating on school uniforms and deciding if they should stay!
