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.
Why We Should Love Clouds
Have you ever looked up at the sky and wondered where clouds come from? Sure, they can form a huge range of different shapes and sizes, but why are they here? Don’t they just block the sunlight on a summer’s day and ruin our holidays with constant showers? The answer is more surprising than you might expect!
Explaining History – And Firing a Steam Train
Have you ever watched someone at work and wondered how they got there, or why they do what they do all day long?
Laura works as an explainer at the UK’s biggest train museum – the National Railway Museum in York. It may seem that steam trains and young women do not go together, but Laura loves it. She spoke to Joanne to explain how she became an explainer, and what she does all day.
Awesome History Resources for Kids
After the popularity of our Science Resources for Kids List, we’ve been asked to make a list of recommendations for history resources for kids.
We will update this list in the coming months, and will concentrate on resources you can access online – YouTube channels, online archives, websites and blogs. Don’t forget to look at the Jump! Mag History archive.

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.
