What is Biotechnology?

Perhaps you have heard of the term biotechnology and wondered what it is. You may think you know already – after all, the parts that make up the word are very familiar: bio + technology. You have seen the first part of the word in biology, antibiotics, all sorts of words. It comes from Greek bios, which means ‘life’.

As for technology, it is not just about computers and smartphones. Technology is the practical use of knowledge to create useful things and solve problems. You might like to think of it as tech-knowledge-y. So, taking it one step further, biotechnology is about using biology in technology.

We talked to Alessandra Iscaro, a biotechnology researcher at the University of Florence, Italy, and she explained to us what it is all about.

Shooting stars, Weather, and Rocks falling from the Sky!

 

 

What do shooting stars, weather and rocks falling from the sky have in common? Are you wondering whether we have gone mad asking such a question? Do rocks ever fall from the sky? Of course they do! You might know them better as “meteorites”, and they are meteors, or rocks from outer space, that fall down to the earth. And what does that have to do with weather? It’s not like they come down like rain! And before you say to yourself “meteor shower”, remember that a meteor is actually a shooting star, a space-rock that burns up in the Earth’s atmosphere. Related, yes, but weather, no.

The weather connection is through another word, generally used to mean “study of the weather”. That word is “meteorology”. As you can see, all three have something in common – the word “meteor”.

So what is this word, and how did it come to mean these different things?

Meteor came into English through French in the late 15th century. In French it was meteore. Very similar, you might think. Does this mean that it is a French word. Not at all. The next question we must ask ourselves is where did French get it from? The answer is from Medieval Latin meteorum, which meant “things in the heavens”. But this is not the end of the tale. Latin took the word from ancient Greek, and in Greek we can analyse the word to see what it really means.

The Greek word μετέωρα (meteora) can be broken into two parts: meta, which means “over, beyond” and aora, which comes from the verb αείρω/ αίρω (aeiro, airo), which meant “to raise, lift up”. Even today, in Modern Greek, αιωρείται (aioreitai) means “it hovers”. All this means that the original meaning of the word was “thing that is raised in the air”. And even in ancient times this developed to mean “things in the sky” and gradually came to have the meaning it does today.

Another interesting point is that the word “air” is in fact from the same root as αείρω (aeiro), which makes it a distant cousin, or cognate, of “meteor”.

 

Did you know:

One of the largest and most famous meteor craters is to be found in northern Arizona, desert of the U.S. It is 1,200m wide, 170m deep and calculated to be created 50,000 years ago! It is more commonly known as the Barringer Crater.

A Short Story – Concrete

Cold, rough concrete beneath my burnt yellow hands, ash under my nails. I hold the butt of an already smoked cigarette in my mouth, looking hopeless. Not even the phrase, “Any spare change?” will get anybody to notice me, the old tramp of Brixton, sitting on the side of a busy main road. Every day I get unhelpful comments from young school kids, such as, “The local druggie! Ha, ha, ha…” These don’t make me feel better. It’s not my fault I’m unemployed, homeless and either drunk or high most of the time. Or is it?

People ask me how on earth I find all the money to buy over fifty cans of beer a week and a rather large variety of harmful grasses from drug-dealers. Sometimes I wonder too. I’ve only ever stolen something once. Twice then. OK! I’ve stolen eight times! Where else am I supposed to get money from (not including vulnerable children’s purses)? But, I’ve been thinking… Maybe, just maybe, it would be a slight possibility – just a slight one – that I could consider starting afresh. By ‘afresh’ I mean a new life in which I give up all my addictions, that are slowly rotting my bones, and make lasting friendships, that won’t break. Ever.
