Ducklings in Disguise

You know the story of the Ugly Duckling of course, who didn’t look like his family but grew into a beautiful swan? Well, this is a true story of three little chicks who are going to grow into beautiful ducks, as told by Susannah Leigh.

It all started when my friend Nic’s very favourite chicken, Rosie became broody. Rosie laid some eggs and sat on them very carefully for a very long time. But the eggs didn’t hatch and Nic realised that they were probably never going to. Sometimes they just don’t.

Poor Rosie – all that patient waiting for nothing.

Drip Drip Drip

Can you imagine not being able to turn on a water tap? Can you imagine not even having a water tap?
Today’s challenge is to notice when you do something that we all take for granted – turning that tap and letting the water flow.
Washing your hands, cleaning your teeth, taking a shower. You are thirsty, so take a big gulp of water straight from that tap after playing outside in the sun.
Every time you turn on a tap of water, think about how easy it was and what you would do without running water.

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.

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.

 

14126405243_c179f6f9b8_qBook 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!

 

2400500463_67988839f0_qWOOL 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!

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.
