How to make a water filter | Do Try This At Home

Blogging science to life

Mon 20 July 2015,

Water is essential to life on Earth. But how does the water get from the rivers and streams to your tap at home? Ross & Heather of the Live Science Team show you how to make a water filter and visit Bristol Water treatment works to investigate the science and engineering behind a glass of water.

If you're around At-Bristol and Millennium Square, you can fill your water bottle from the new, free, public water fountain on Millennium Square, thanks to the folks at Bristol Water.

Steak, cake and brown sludge!

Blogging science to life

Fri 10 July 2015, David Judge

David from Live Science Team explores why browned food tastes so good!

Almost every day I walk past the back of a bakery and I’m tempted by the delicious aromas of freshly baked goods. Sometimes I give in. I love baked foods and I love baking. But it has always seemed like a bit of a dark art to me. You put a soggy mess into the oven and out comes something delicious. As it turns out, chemistry has an awful lot to do with it. One reaction in particular, which was discovered over one hundred years ago, is responsible for the whole variety of aromas which lure me through the bakery door.

Cake chemistry
Find out more about the chemistry of baking on our YouTube channel

The story of this chemical reaction takes us on a journey through the 20th Century, back to France, 1912, when chemist Louis-Camille Maillard was trying to imitate in the lab how the body makes the proteins it needs to live and grow. Maillard noticed that instead of reacting as he expected, the sugars and amino acids which he had mixed together slowly turned into a brown sludge.

Brown sludge, politely called melanoidin, unsurprisingly failed to capture many scientists’ interest, and the Maillard reaction, as it is called, remained unstudied for several decades.

Mallards
That's Maillard... not Mallards.

However the Second World War revived interest in the reaction when it was noticed that processed foods eaten by the troops, such as powdered eggs and tinned food, would slowly turn brown and taste unpalatable. Once they had worked out that it was the same reaction which had made brown sludge in the lab, scientists focussed on how to stop the Maillard reaction from happening at all. It seems strange that the same reaction which makes the crust on a nice bread roll so delicious is the same reaction which can make some foods taste bad.

It wasn’t until 1953, when an African-American scientist, John Hodge, put together all of the pieces of the puzzle, that we really understood exactly what was going on. During the process, which works best between 140 and 165˚C, amino acids, the building blocks of proteins, react with sugars. Both of these types of chemicals are found in almost all types of food, in an abundance of variety. When this reaction occurs, hundreds or even thousands of products can be formed, each depending on the amino acid which they came from. These contribute to the aromas and flavours of foods such as meat, popcorn, caramel, cake, onions, chocolate, bread...

Roast dinner
We can thank the Maillard reaction for roast dinners and pints too!

...Basically, if it is brown, the Maillard reaction probably had something to do with it!

Nowadays scientists aren’t just interested in stopping the Maillard reaction when it makes food taste bad, but they also try to control it to create certain flavours and aromas. In fact every time we cook we are using this reaction, even if you’ve only ever just made toast.

I’m not sure if knowing about the Maillard reaction will help me to resist what’s on offer at the bakery, but maybe next time I’ll at least pause for thought before wolfing down a tasty treat.

Brain Lab: Thinking Tissue - key findings

Blogging science to life

Fri 3 July 2015, Jennifer Garrett

As a leading UK science centre, we are always looking to deliver novel and exciting programmes. Building partnerships is a great way for us to develop and deliver activities that are new for us as well as our audiences.

During March 2015, some of our visitors joined us for our innovative Brain Lab sessions. The project, supported by the Wellcome Trust, explored the impact of using real human tissue on visitors’ learning experiences. We did this through the development and delivery of an immersive workshop to recreate ‘behind the scenes’ science happening in hospital labs to diagnose brain tumours.

Many visitors kindly offered to speak with our evaluators about their experiences. It is thanks to their contributions that we are gathering our findings from the project, and we want to share a summary of some key findings so far:

We're currently working on the full report, so if this summary whets your appetite for more, or you have any feedback, please get in touch with the project team:


Brain Lab: Thinking Tissue is a partnership project with Brain Tumour Bank South West based at Southmead Hospital, the Centre for Ethics in Medicine at the University of Bristol, and At-Bristol Science Centre.

Volunteers' Week: Meet Ian Montgomery-Sporle!

Blogging science to life

Sun 7 June 2015, Jennifer Garrett

To celebrate national Volunteers' Week, we caught up with our fabulous volunteer Ian Montgomery-Sporle!

Ian in action

Tell us a little bit about yourself! 

When not volunteering down with At-Bristol I work as a full time member of staff for Ford retail within the Finance division.  I have been in Bristol and with Ford for almost 8 years after my move from Brighton, back to my old university town of Bristol.  At university I studied Nursing over at UWE, and have recently completed a stint with Open University doing Astrophysics.  

How long have you been volunteering for At-Bristol?

I have recently reached my 1 year anniversary with At-Bristol after completing my first full day with Live Science Team on 24 May 2014. Oh how time flies when you’re having fun!

Why did you decide to volunteer with us?

The driving force behind me wanting to join the volunteering programme with At-Bristol is that my partner and I wished to adopt, so I needed experience working with children with a full spectrum of ages.  I was told I only needed to do about 1 week with children, however to date I’m just shy of 9 weeks in total!

What do you like about volunteering?

The staff and other volunteers within At-Bristol are to me an extended family. Not only are they there to talk, assist and guide you through the day, but are also have snippets of information and knowledge that can be of great assistance when dealing with the public, but also outside of that environment.

What’s been your favourite moment so far? 

To date I can’t really think of anything I haven’t really enjoyed doing.  I am lucky to have been able to have had a holistic view of pretty much all areas within Live Science Team & Marketing, being in and out of At-Bristol, on Millennium Square or in a barn at Dayelsford Farm! The journey has and still is very enjoyable and I look forward to many more sessions ahead.

What advice would you give to someone thinking of volunteering? 

I would advise anyone to come down and volunteer here. It gives you a great chance to discover more about science, and science communication.  You will gain confidence and knowledge, and you get to work with a great bunch of people who's combined knowledge is pretty astounding!
