Fact or Fable? Most body heat is lost through the head
Many people believe that you should keep your head covered during cold weather, as most body heat is lost through the head. It’s certainly true that any part of your body that’s exposed to cooler air will lose warmth; heat always moves from something warm to something cooler (that’s called the second law of thermodynamics). And our heads and faces are more sensitive to changes in temperature than other parts of the body.
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.
About the Author
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’s in a name….?
Do you ever wonder why people can’t pronounce your name correctly? Or struggle to say a friend’s name right sometimes? Here Avani tells us about her experiences, and how we can make the effort to pronounce things as best we can!
Do people always get your name wrong?
My name is Avani and let me start by saying: I get it.
Sometimes I spend ages teaching someone how to say my name properly (Uvni would probably be the best way to write how it’s pronounced) and other times I really can’t be bothered. I wish I had an easier name, or that people would just work harder to get it right!
Why do we find some names really difficult to pronounce and others really easy?
Here in England, people have names which come from all over the world. These names might be from places where a different language is spoken, and the different languages may also use different letters or characters to those we use for English.
My family, for example, come from a part of India called Gujarat. The Gujarati language uses a syllabary (a set of sounds) rather than an alphabet, but the syllables don’t always match up with English letter. The ‘v’ in ‘Avani’ (વ in Gujarati script) should actually be pronounced somewhere in between the English ‘v’ and ‘w’ sounds, but there isn’t an English letter that sounds exactly the same and this makes my name harder for people to remember! Also the ‘a’ and ‘u’ sounds in Gujarati are written using variations of the same symbol (અ (u) and આ (a)), which is why my name is spelt with an ‘A’, but pronounced using a ‘U’. Here’s what ‘Avani’ looks like written in Gujarati: અવનો – cool, right?
Languages which do use the same letters as those in English, may not pronounce all of them in the same way. This means that names that look similar on paper may be pronounced differently depending on where in the world someone lives. In Spanish, for example, the ‘j’ and ‘x’ letters are more like (but not identical to!) the English ‘h’, and in German, the letter ‘j’ sounds more like the English ‘y’ – can you imagine all the different ways people around the world must pronounce ‘Jesus’? You can listen to a few here!
It’s not only names from other countries that are hard to pronounce though! Have you ever thought about which common English names might be tricky for someone learning the language to get their head around? What about the name ‘Thomas’? We say it with a hard ‘T’ (like the one in ‘tree’, rather than the one in ‘three’) even though it is spelt with a ‘Th’, and we say the name ‘Charlotte’ with a ‘Sh’ sound (like in shop) even though it is spelt with a ‘Ch’ (like in chop). It must be hard to keep up with which names follow the usual pronunciation rules (like Theo or Charles) and which ones don’t!
What can I do if I think I’m pronouncing someone’s name wrong?
It is always worth checking with someone if you think you’re saying their name wrong – even if you’ve known them for ages and are embarrassed about asking, chances are they’ll be really glad to have an opportunity to correct you! However, it’s also important to remember that even if you know that the way someone says their name is different to the traditional way of saying it, you should always say their name like they have asked you to. Many people living in England, for example, prefer to go by a nickname or a more ‘Anglicised’ (English-sounding) version of their name to make things a little easier – so if you know a ‘Jesminder’ who prefers ‘Jess’, or a ‘Paulo’ who prefers ‘Paul’, you should respect their decision!
If you’ve just met someone new and have forgotten how to pronounce their name (or even if you’ve met them a few
times) – don’t despair, they probably won’t mind if you ask them again! If you are too embarrassed, though, there is a huge variety of pronunciation websites out there which will be able to help you. Click here for a good one!
Do you have a hard-to-pronounce name? Or have you ever been in an embarrassing situation over getting someone’s name wrong? Do you live in another country – which English names do you really struggle with? I’d love to hear your stories!
As well as trying to get people to say her name right, Avani Shah is currently working on a book for 8-12 year olds. She also blogs about her childhood and teenage experiences (Away with the Mice) and writes about words, etymology, and spelling for a website called Spellzone.

Under the Sea with the RRS Discovery
Last month the The RRS Discovery, the most advanced research ship was launched in Southampton.
At £75 million it is one of the most expensive research ships ever commissioned. It measures at just over 100 metres long, with seven main laboratories and a bridge like the Starship Enterprise! It has just begun expeditions around the British Isles, currently examining the UK’s continental shelf, a band of sea floor around 50m-100m deep.
“These shelves are really very important,” says Dr Sanders from the National Oceanography Centre in Southampton. “There is a lot going on in the shelf seas and we need to understand how they work so we can safeguard their future.”
