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.

Vet Against The Odds

Hello! My name is Lauren, I’m 22 and I’m at university training to be a vet. Like most vet students I like science and animals, what makes me a bit different is that I am partially deaf in both ears. I wanted to write about what it’s like to go to university and move away from home when you can’t hear properly.

My parents found out I was deaf when I was 5 years old, just after I started school. My sister is also hearing impaired and Mum had inadvertently taught us both to speak properly, which meant that doctors didn’t realize there was anything wrong. When I got older mum told me that she was really worried at the time that being deaf would affect what I was able to do in life, but so far it hasn’t.

Winter Wonderings – Are Snowflakes Really All Different?

 

It’s a common belief that no two snowflakes are the same, and in a way this is true. No snowflake can ever be completely identical to another, because when you get down to the molecular level they will have slightly different kinds of water molecules, different electrons and different traces of other materials such as specks of dust.

However, if we’re talking only about the appearance and shape of a snowflake, then yes it is possible that some will have duplicates. Snow crystals can vary from fairly simple, hexagonal structures to the more complex and delicate shapes that we commonly think of as snowflakes.

The simple flakes have far fewer molecules than their larger cousins and so it’s entirely possible that you could find two that appeared identical when viewed through a microscope. The more complex structures, however, can have more than a hundred different features and each feature can form in a number of different ways. This makes it highly unlikely that you would ever find two large snowflakes that looked the same – but you could have fun trying!

Great Women You Should Know… Hedy Lamar

You probably do not know who the actor Hedy Lamarr was as her last film credit was in 1958. If you ask your parents they may have a vague recollection or at least know her name.
What they probably don’t realize is that she wasn’t only an actor. She was a philosopher and, most importantly this month as we remember the World Wars and the sacrifices made during those wars, she was an inventor. She and avant-garde composer George Antheil worked together to create the first broad-spectrum frequency hopping wireless communications.
“What on earth is that?”, you’re probably thinking!
