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.
Being an expat is not the easiest thing in the world, but it’s certainly is one of the most interesting and enriching experiences one can have. Alexia moved from Athens to London in September 2012, and is still trying to figure out expat life, armed with optimism, patience and lots of enthusiasm. She explains how she finds life… here and there.
Here: I meet new people all the time and develop great friendships with people from all over the world. I’m more open socially than I was back home.
There: Although I miss them terribly, I’m so happy every time I go back home and see my old good friends and my family. Every reunion is filled with lots of hugs and happiness.

When we published our article 6 Things Parents Wish Their Kids Would Do … and 6 Things Kids Wish Their Parents Would Do, one of our readers got in touch to say we should do one for the things that kids with special needs wish EVERYONE would do. So we asked our followers, and came up with this list.
It was a bit tricky to put the list together, because there are so many different kinds of “special needs”. For some children, their disability is quite well manageable with medication, or with assistance and therapy, and you’d hardly know they had any additional needs. You may have heard of autism or Asperger’s Syndrome – these are part of the autistic disorder spectrum, a range of conditions that affect how people communicate and relate to people around them. You can’t tell by looking at someone if they have ASD.
Other children have disabilities that are apparent when you meet them, such as those with Down’s Syndrome, which we have covered in more detail here. Or they might use a wheelchair to get around.
What thing do they all have in common? They sometimes get asked really silly questions, and get treated badly by people. Make sure you aren’t one of them, by listening to what the kids (and their parents) had to say!
Until 3 billion years ago, Mars was a wet planet much like Earth. It had land, an extensive atmosphere and an ocean that covered two thirds of the northern hemisphere as well as smaller bodies of water. But significant climate change caused the water and atmosphere to boil away, leaving Mars a dry and arid planet. Or so we thought… then came the news from Nasa – Water found on Mars!
