Have you ever wondered…about your teeth?

Have you ever had a tooth pulled out by a dentist? If you did, you may have noticed something odd. The roots were probably still attached to the tooth, unlike when a tooth falls out normally. What happens to the root of a tooth, how do teeth grow and why is it important that you take care of them? Samantha Gouldson investigates!

Unsung Heroes – Lollipop Men and Women

Is there a Lollipop Man or Woman on your road to school? Do you know his or her name?
When I take my children to school, we walk  if we can, because the parking situation near the school is a bit difficult. On our way we cross the road where the Lollipop Man stands guard.
He isn’t particularly talkative, but is friendly and helpful. It has been warm these past days, and still he stands, in his reflective jacket and ear-muffed reflective hat. I am waiting for him to take the hat off, he must be sweltering under there. Perhaps he has a lighter hat in his cupboard, which doesn’t get worn until summer.

Do Earwigs Really Live in Our Ears?

do earwigs really live in our ears

There has long been a myth that earwigs use human ears either to lay their eggs or to live in and feed off our ear wax, or other similar things. It sounds pretty gruesome, doesn’t it? After all, who would actually like the idea of an insect living inside their ear? But do earwigs really live in our ears?

Fortunately for us, it is not true. Despite their name, earwigs don’t actually live in our ears and neither do they use them to lay eggs. They much prefer their normal habitat of nests under rocks and logs or in flowerbeds. So where does the earwig get its name?

 

Old English Origins

Yet the name itself suggests that this has been a myth for a long time, so let’s examine the name. It can easily be split into two parts: ear and wig. These two parts both come from Old English; which is what we call the language as it was spoken when it was first written down, right up to the tenth century. So this would include the period of Kind Alfred the Great; he of the burning cakes.

In Old English, the words were eare and wicga. The first part, which you can recognise quite easily, meant ‘ear’. But the second part, wicga, meant ‘insect, beetle, worm’. The interesting thing is that it came from a root that did not have anything to do with insects at all, but instead meant ‘wiggle’.

Think about how even today we say ‘wiggly worm’; or think about how you would describe the movement of a caterpillar. You can see how this word came to be associated with insects. So if we put the two parts of our word together again, we have ‘ear-insect’. It seems that our very early linguistic forebears did indeed believe that earwigs lived in the ear.

Blame it on the Romans

But where did this myth that they dwell in our ears come from? It is not unique to English; in German it is known as Ohrwurm, or ‘earworm’, and it is the same in Welsh with pryf clustiog; while in French it is perce-oreille, or ‘ear-piercer’.

To find the origins of the myth, we have to go back in time all the way to the days of the Romans. In around 77 CE, Roman naval commander and writer Pliny the Elder published his work Historia Naturalis, or Natural History.

In it he writes about a great deal of the natural world, including insects. It is here that the myth may have begun, as he writes about earwigs getting into the ear. Perhaps he saw one that had happened to go into the ear by chance, much as a fly or a spider might, and jumped to the wrong conclusions.

The Pincer Insect

Other languages have taken the name from the apearance of the insect; in Italian it is known as forbicina, and in Spanish it is tijereta, while Greek has ψαλίδα [psalida] All three of these translate as ‘little scissors’, deriving from the pincers that the earwig uses to catch its prey.

Water and Engineering – Water, Wonderful Life

water and engineering

Dr Lesley Beeton is a scientist, who studies what the DNA code tells us about human life and health. She has always loved science, and believes that science doesn’t just happen in laboratories. It happens all around us. Science keeps aeroplanes flying, electricity flowing, and the internet speedy.
Dr Beeton  grew up in South Africa. Some of you may have traveled there for your holidays, to see the game reserves or Table Mountain. But even if you haven’t been there, we can all still learn something from the experiences of southern Africa.
