A Day In the Life Of…a Biologist
Ever wondered what being a biologist might be like? No two scientists work days are the same but I’m going to take you through my typical day to give you an idea
7 AM: I get up and eat breakfast (toast and a cup of tea) before travelling to work.
8 AM: I arrive at work (this is early for scientists, most of my workmates arrive at about 9 AM but I like to get up early!) After checking my email the first job of the day is to turn on the microscope above.
The plant root surface is covered in root hairs. This is what they look like under a microscope.To get an idea of the cells, les than 1mm of plant root can be seen in this image
It is similar to microscopes you may have used at school but with a few added features including a special camera. I am fascinated by plants and in my research I am trying to find out more about how some plants (including peas and beans) can form a friendly relationship (known as symbiosis) with soil bacteria, which provide nutrients that the plants need to grow. I use the microscope and camera to study living cells in plant seedling roots (where the symbiosis is set up).
10:30 AM: Tea break and seminar. I have a tea break with some of my workmates and then go to a seminar where other scientists talk about their research and we discuss it afterwards. Seminars are a great way to find out what experiments other scientists are doing, and to get ideas for new experiments to try.
12:30 PM: I have lunch with my friends.
1:15 PM: More experiments. For some of my experiments I have to grow plants in greenhouses. Today I visit to check on my plants and collect some to take measurements. This involves digging up the plants and cleaning them to look at their roots. This is fun, but messy!
3:30 PM: Afternoon tea break.
3:45 PM: Data analysis. I spend the last part of the afternoon drawing graphs of the data I have collected today and thinking about what it shows (does it answer the research question? Do I need to do further experiments?). I also spend some time reading research articles to find out about experiments other scientists have been doing.
5:30 PM: Hometime! Once I am home I have dinner and then relax.
One of the things I love about being a scientist is the feeling of discovering the “unknown”. The experiments I carry out reveal little details that when combined with other scientist’s data can help us build up a picture of how the plant-bacteria symbiosis is set up so that pea and bean plants can get the nutrients they need to grow. We hope that this knowledge might be able to help improve farming in the future.

Sarah Shailes is a plant scientist working at the John Innes Centre, Norwich, UK. She studies how some plants can form a friendly relationship (symbiosis) with soil bacteria, which help the plants gain nutrients they need to grow. When she isn’t in the laboratory she enjoys knitting and hiking, and helps run a local Brownie Guide unit.
What is Separation of Powers?
Have you ever heard this term and wondered what is the separation of powers exactly, and why is it so important? If so, then read on because we are going to explain it!

Separation of powers isn’t a new idea – in fact, even the Ancient Greeks had a version of this political system, as did the Romans. There are variations in place across the world.
Each country has a slightly different setup, so we’ll use the United States to explain the concept.
What is the Separation of Powers?
The idea behind it is to have a system in place that prevents one person or group from having all the power over an entire country. If you think back to the days when countries were ruled by a king or queen, who made decisions that affected the lives of everyone who lived in their kingdom – sometimes that went well, but often it didn’t. Instead of one person having all the power, a democracy splits the power between different people or groups of people.
When you think of the person who runs the country, you probably think of the President. The President represents the EXECUTIVE branch of the government.
In the USA, that means that the President executes the instructions of Congress, signs Executive Orders, selects judges to be approved by Congress, and is in charge of the armed forces (the navy, army and airforce).
By the way – don’t get confused by the word ‘execute’, which can mean ‘to put to death, to murder’ but can also mean ‘to carry out, to accomplish’. The President carries out the instructions from Congress, he doesn’t kill them all!
History of South Africa – Written by Bruntville Primary School
The pupils of Bruntville Primary School have written a short article about the history of South Africa, and an explanation of Apartheid.
What Was Apartheid?
Apartheid was a system that existed in South Africa that separated people based on their ethnicity and skin colour. It became law after the National Party won the election in 1948. They declared many areas as only for white people, and discriminated against people of colour (POC).
Exploring Australia – Marvellous Melbourne
Continuing on my Australian adventure, I thought I’d tell you about Melbourne, my new favourite city. Whilst I’m in Australia, I’m going to be staying here in Melbourne, then moving on to Sydney next week. Sydney, I know about; there’s a big harbour, famous for its bridge and its opera house. But Melbourne? Before I came here, I didn’t know a thing about it.
The first thing I found out is that Melbourne is in the South East of Australia, in the state of Victoria. It’s on the coast and like Sydney is a harbour city. The climate in Melbourne can be a bit like the UK; it changes often and can start raining out of nowhere! Although it gets hotter than the UK, it doesn’t get quite as hot as the rest of Australia.
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.
