Winter Wonderings – Can It Really Be Too Cold for Snow?
Have you ever heard someone say that it is ‘too cold for snow?’, and wondered if this was true. Our Science Correspondent Samantha looks at the science behind this claim.
Be a Good Communicator
Have you ever said something that was misunderstood by the person you were talking to? Do you know anyone who sometimes says things in a way that seems rude and abrupt? It is not always the words used, but the way in which they are used.
Good communication is very important. Carolyn Ward explains what it is and how to be a better communicator.
A Kid-Friendly Explanation of The Big Bang & An Amazing New Discovery by Scientists
Most scientists believe that the Universe began in a Big Bang around 14 billion years ago. The entire Universe was inside a bubble thousands of times smaller than a pinhead, and was hotter and denser than anything we can imagine.
When the explosion called the Big Bang happened, the Universe as we know it was born. In a fraction of a second, the Universe grew from smaller than a single atom to larger than a galaxy. It kept on growing, and is still expanding today.
Now researchers in America think they have found traces left in the sky that prove this that the Big Bang did really happen. It takes the form of a distinctive twist in the oldest light detectable with telescopes. These twists of light are called ‘gravitational waves’ – the effect is a little bit like how waves form on the surface when you drop a big stone in a pond. However, you also have to imagine that the Big Bang formed the pond itself.
The team leading the project, known as BICEP2, has been using a telescope at the South Pole to make detailed observations of a small patch of sky. The aim was to find evidence of ‘inflation’ – the idea that the cosmos grew rapidly in its first trillionth, or trillionth of a trillionth of a second – growing from something unimaginably small to something about the size of a marble.
The leader of the team, Prof John Kovac of the Harvard-Smithsonian Center for Astrophysics said:
“This is opening a window on what we believe to be a new regime of physics – the physics of what happened in the first unbelievably tiny fraction of a second in the Universe.”
Over the coming years, scientists will work hard to investigate every aspect of this discovery. Other experiments will be carried out to see if they can replicate the findings of the American team. If this research is confirmed, it will be one of the greatest scientific discoveries of our time.

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.
