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.
Being a Teenage Vegetarian
What do you do when you want to become a vegetarian but your parents aren’t too keen? Tabitha explains how her family reacted to her decision, how they have adapted to having a teenage vegetarian in the family and how she eats healthily without meat.
Like a lot of teenagers, I decided to become a vegetarian. Some do so because they want to rebel, some people think it will be healthier, or just don’t like meat that much. I was convinced to go veggie when I was 13 after a biology dissection. It was only a rat, but it made me realise that I didn’t want to be eating animals as I have a pet rabbit and it was just too close to home for me. Also, a Jamie Oliver programme I accidentally watched featuring the making of sausages put me right off… But mainly for me, it was the animals.
Let Toys Be Toys
Have you ever noticed that children’s toys are often labeled as “Boys” or “Girls” toys?
Very often, the girls’ toy area will be a sea of pink and glitter with a lot of beauty, cooking, fashion and baby doll items. The boys’ area will have action figures, construction and science kids, plastic guns and dinosaurs. Even board games can sometimes be separated in this way. Tina takes a closer look at why this is unfair for all kids, and what a group called Let Toys be Toys are doing about it.
Where Does the Word Candidate Come From?
Today is election day in UK, when the citizens of the country choose their new government. You can read all about how the elections work here. You wouldn’t think that dress codes of ancient Rome would affect the elections of today, but they do! Millie Slavidou explains.
Today is a good day to think about the word ‘candidate’. I rather like the etymology of this one.
It comes from Latin candidus, which is the past participle* of candidare, which meant ‘to make white, to make bright’.
Not because of whitewashing whatever the candidates might have said or done! It was because in ancient Rome candidates who wanted to be elected either to the Senate or any other office wore white robes.
If we take it one step further back, to a root meaning ‘white, shining’, we find that ‘candle’ is a cognate.**
*Past Particle
The past particle is the past form of the verb that can also be used as an adjective, like “a fallen tree”. In the case above, the adjective is like saying ‘whitened’ in English. Other examples of past particles are:
verb: bite
past particle: bitten
example: a bitten apple
verb: choose
past particle: chosen
example: aa chosen present
verb: crash
past particle: crashed
example: a crashed bicycle
**Cognates
A cognate is a distant relative, a word ultimately from the same root. Like a third cousin. Here are some examples of cognates.
Book is related to beech. Well, actually, book means beech! Both come from Germanic word meaning beech tree, Buche.
Germanic runes were originally inscribed on tablets made of beech wood. Modern German for book is Buch!
WOOL and FLANNEL are distant cognates. Today, fashion stores often describe plaid shirts as ‘flannel’, but it is actually a soft woven fabric, originally made of wool, but now often cotton or synthetic. You might have a flannel pyjamas, which are lovely and cosy in the winter!The word wool is from a Proto Indo European root *wele meaning ‘wool’.
In Welsh, the word gwlanen, means ‘wool’ and is from the same root. The word flannel comes from the woollen vests that were made, presumably by Welsh traders from Welsh sheep – Gwlanen became fwlanen, and then flannel. So wool and flannel are distant cousins!
Today’s featured image is Marasmiellus candidus, a type of mushroom. You will often find the word ‘candidus’ used in botany or biology to describe something that is white, such as crocus candidus or the white woodpecker Melanerpes Candidus. There is even a white monkey called Propithecus candidus.
