How to Eat Healthily With Food Allergies
Writer and blogger Kate Thompson has four children. Kitty and Archie are eight years old. Along with their older brothers (aged 12 and 16) they suffer from food allergies, in their case “gut allergies” called non IgE allergies which you can’t test for.
The more well known allergies are IgE allergies – these are the ones which bring an instant reaction – sometimes this reaction can be very dangerous, and the person cannot breathe properly.
Are Rewards the Right Approach? Written By You
14-year-old Gabriella told us that her school gives lots of rewards for doing well, or for good behaviour. It got her thinking about reward systems, and if they are a good idea.
I’m sure everyone has been offered a reward for doing the right thing at some point in their lives, whether it has been your parents rewarding you for your actions or teachers at school.
When you are presented with the idea of a reward it makes you want to succeed right? Or does it? I know from personal experience that people aren’t necessarily excited by the prospect of being given a reward and when they are, they are usually set on the reward and not the idea behind it. For example, prizes for winning competitions often attract entries and participants often enter because of the prize and not because they are really interested in the theme of the competition. The same kind if thing comes out of rewards at school.
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.

The British Skeleton Team – Sliding to Victory
How would you like to slide down a very steep and winding track of ice on something very similar to a tea tray at around 140km per hour? Yes, no, maybe. Well, there are people out there who can and do want to. And what’s more, they’re really rather good at it.
Alongside Bobsleigh and Luge, the Skeleton is one of three sliding sports that take place on artificially refrigerated ice tracks. It’s a really white knuckle experience as each skeleton athlete pushes their sled one handed away from the start before lying down with their face first as they travel the track, using their shoulders, knees and toes for steering.
