IET Open House Day
The Institution of Engineering and Technology held their Engineering Open House Day on 3 August 2018 for young people and their parents to learn what it’s like to work as an engineer, and MetaboLight was invited to be part of the University College London Engineering booth to inspire people!
We had a rush of enthusiastic youngsters interested in STEM pour into the hall, and had a blast explaining how we use certain wavelengths of light to measure brain oxygenation and metabolism. Some of the visitors were thrilled to see what this technology can do and how it has already helped save so many baby lives. We hope more people learn about Near-Infrared Spectroscopy and that more can benefit from this technology in the near future!
Bella: A GCSE student’s one week research secondment with the MetaboLight team
My name is Bella and I’m 16 years old. I’ve just finished GCSEs and next year, I hope to study biology, chemistry, maths and further maths at A Level so I can go onto pursue a career in medical research. I contacted the MetaboLight team in the hope to gain some experience to find out what working life is like in a research lab.
Upon first impressions, I felt welcomed into the department as I met many of the team’s friendly faces. I had the pleasure of spending the majority of my week with Gemma Bale, who showed me the NIRS device she had developed called Cyril. I spent most of the 5 days experimenting and using Cyril to monitor effects of occlusion of the arm including concentration of oxyhemoglobin, concentration of the enzyme CCO and hyperaemia over different time intervals. I was particularly impressed by Cyril’s ability to accurately measure many things about the patient non-invasively.
Over the week, I learned not only how to use Cyril, but how to accurately record results and analyse the data. I also learned a lot more about the different types of medical imaging from NIRS to ultrasound, the process of metabolism and how to use lots of the lab’s equipment. In addition, I got the opportunity to sit on a panel of scientists where we gave feedback to a group of mature students who were pitching ways to educate people, particularly children and teenagers, on medical engineering. As the target audience for many of the pitches, I represented the teenagers by giving feedback and asking questions on their proposals.
Overall, it was a really exciting opportunity and I feel very fortunate that I got to spend the week in the medical physics department. It has inspired me to continue to pursue my dreams to become a researcher in the future!
Max Burgess: An A-Level student’s one week research secondment with the MetaboLight team
I am an A-level student who has just finished year 12 and am studying maths, further maths, physics and computer science. Once I finish my A-levels I want to go on to study computer science or electronic engineering at university.
My first impression was mostly how friendly everyone was. I was also surprised how all this research had been done by such a small team. I think I only saw 8 or 9 people my whole time there (maybe there were more and I am forgetting some people).
On the Monday I met Ilias, he gave me a brief overview of what fNIRS was and how it worked, and also showed me a prototype for a new smaller version of CYRIL that was early in development. After this, Gemma and Isabel showed me the original Cyril and explained how it worked. After this Josh showed me some of the code behind the simulations that he had made. Then on the Tuesday I watched Zuzana do a phantom experiment with Cyril. The phantom was a tub filled with a blood-water mixture. This was used as it mimics the composition of someone’s brain. After this I started the investigation into the U parameter (metabolic demand) on the simulations. On the Wednesday Fred showed me a machine that is similar to Cyril except instead of measuring relative amounts of light going in and coming out it could measure the total number of photons in absolute terms. I then continued the investigation into the U parameter. Then on the Thursday I did more coding with Josh and finished the investigation into the U parameter. On the Friday I went to the Institute of cognitive neuroscience and Paola showed me a fNIRS headset that they use when they do the experiments out on the street.
The thing that impressed me the most was all the equipment. I was also impressed by the fact that if they needed a certain piece of equipment or a piece of software they mostly made it themselves from scratch.
I learnt so much as before I came I didn’t know anything about fNIRS or the anatomy of the brain but after I feel like a have a pretty solid grasp on how fNIRS works and I also learnt some of the anatomy of the brain.
I don’t know what I plan to do next. Before I spent my week at MetaboLight I was pretty certain that I wanted to do computer science but the engineering side was so interesting that I am now thinking about possibly doing electronic engineering.
Workshop for Waltham Forest Virtual School
The MetaboLight team was thrilled to be part of an experience programme organized by UCL and Waltham Forest Virtual School to introduce higher education to children in care! The whole workshop lasted for 2.5 hours, starting with students playing around a “science circus”, where they could rotate around different stands and learn how light interacts with the outer environment. Then students had a hands-on experience in building their own electronic circuits through learning basic circuitry. They were remarkable and were able to build all circuits by themselves!
Finally, students had a chance to see their brain scan, and were really excited to see each others’ scans! Overall, we enjoyed the session very much! We were even happier when helpers from the virtual school said that our session was the highlight of the 2-day summer school. We hope to help out in more of these activities in the future!
London Regional Big Bang Fair at Sutton Grammar School
MetaboLight was overjoyed to be part of the London Regional Big Bang Fair at Sutton Grammar School on 13 and 14 July 2018! Lots of interested students from 38 different schools poured into the school halls on Friday, with an estimated of 2000 students altogether on that day. The hall was filled with a fun atmosphere full of science and technology, with everyone coming to our stand with enthusiastic interest in how we use light to measure brain power, and leaving with delighted smiles as they saw their brain activity and hand scans.
Saturday was open to public, and we were more than happy to share our research with families and people from all backgrounds. It was a wonderful event, and we would like to thank Sutton Grammar School once more for organizing such a well-planned event!
After the event, we gathered a lot of positive feedback. One of the responses from a year 7 student was remarkable, and we are overjoyed to see that the student had enjoyed our activities:
I will be talking about a particular biological stand that involved the volunteer to do mathematics. You may ask why? Well as soon as you sit down into the testing chair, you will have an oxygen reader strapped to a headband placed on your forehead. This measures your brain’s oxygenation and metabolism. This was very interesting and I got to improve my mathematics. I enjoyed this stand very much and I learnt that my brain takes in a lot of oxygen while thinking but very few of that oxygen is used. This has led me to take much more interest in the human brain and its functions. It is amazing.
UCLH Research Open Day
The MetaboLight team works hand-in-hand with University College Hospital (UCLH) as a unified group of clinicians, engineers and scientists. On 5 July, UCLH held its Research Open Day, where MetaboLight was invited to demonstrate how we use light for clinical purposes.
Groups of eager students came to UCL Department of Medical Physics and Biomedical Engineering to see our demonstrations – from understanding transmission properties of light with our hand scanner, to application of light to measure brain oxygenation and metabolism with our brain scanner!
We were extremely happy to see the excited faces of the students when they could see their monitored brain activity! Great big thanks to UCLH for inviting us to this event!
Big Bang Event at The City Academy, Hackney
Our MetaboLight team was delighted to help out with the Big Bang Event at The City Academy, Hackney! We taught 6 one-hour long sessions, and reached a total of 123 students ranging from years 8, 9 and 10.
The students were enthusiastic and enjoyed the electronics class that we had prepared for them. They learnt how to read electronic circuits and how to build an LED circuit where they could turn on the LED with a button and also control the intensity of the LED with a potentiometer!
Finally, we scanned 12 of their brains and saw their oxygenation and metabolism increase when doing math tasks! The students were extremely excited to see the results of the brain scan!
Annual Teacher Conference
The Annual Teacher Conference was held on 25th June, and MetaboLight held an hour-long session for 25 science and physics secondary education teachers and inspired them with methods to carry out education regarding optics. This sparked discussion among teachers as they tried to pinpoint how and where they could use these workshops in the classroom with their students.
Afterwards, we shared our life-saving research with them, introducing them to our research and instrumentation. The teachers were interested and fascinated with our technology, and were pleased with our efforts to help save baby lives!
International Women in Engineering Day
22 June 2018 was another busy day for MetaboLight – we were invited to help out in celebrating International Women in Engineering Day!
We met many enthusiastic girls who were passionate about engineering, and showed them what engineers do and their significance to the society. We conducted hand scans with light that can penetrate through their hands – and many of them saw their blood vessels in real time! We also scanned some of their brains and measured their brain oxygenation and metabolism, which many girls found fascinating!
We reached out to 114 year 12 girls that day – and hopefully will continue to inspire more people throughout the year!
Dr Gemma Bale Awarded the Isambard Kingdom Brunel Award Lecture for Engineering, Technology and Industry
Our MetaboLight team member Dr Gemma Bale has been awarded The Isambard Kingdom Brunel Award Lecture for Engineering, Technology and Industry by the British Science Association (BSA) as part of its prestigious Award Lectures for 2018.
As an Award Lecture winner, Dr Gemma Bale has been invited to the British Science Festival in Hull, where she will introduce her life-saving research to everyone! Dr Bale will discuss the hugely important topic of brain injury in newborns, which is a leading cause of infant mortality. She will also showcase her pioneering work applying an infrared light technique to monitor baby’s brains, which is giving hope to the lives of many affected families.
Dr Gemma Bale Awarded BSA Media Fellowship
We are overjoyed to announce that our team member Dr Gemma Bale has been awarded the BSA Media Fellowship 2018!
The BSA Media Fellowships provide a unique opportunity for practising scientists, clinicians and engineers to spend two to six weeks working at the heart of a media outlet such as the Guardian, BBC Breakfast or Buzzfeed.
We congratulate Dr Gemma Bale, and wish her the best in her research and public engagement activities!
The Brilliant Club Scholars Programme
Research Associate Dr Gemma Bale, and PhD students Isabel de Roever and Pardis Kaynezhad have been working with the Brilliant Club to inspire talented Year 8 pupils from under-represented backgrounds to apply to study medical physics and biomedical engineering.
In partnership with The Brilliant Club and UCL Engineering Education, Dr. Gemma Bale (BORL) has designed a six-week Key Stage 3 course, Illuminating the Body, for the programme to teach Year 8 students about the engineering design process, the application of physical principles to the design of machines, and how scientists interpret data.
The course is being delivered by 31 tutors all over the country, reaching almost 400 pupils! Two PhD students from BORL are delivering the course, Isabel de Roever and Pardis Kaynezhad.
International Day of Light
MetaboLight members were invited to exhibit at the Institute of Education to celebrate the International Day of Light with groups of young people enthusiastic about science and engineering – and light!
Out of the 250 people that visited, we scanned around 20 brains and 40 hands in total, and the students were excited to see how their fellow schoolmates responded to mathematics questions and how this affected their brain activity! We also found out from a survey that everyone enjoyed their experience at our booth – and learnt a lot about medical physics and biomedical engineering after visiting us!
We are overjoyed to hear that students from Tiffin school loved our brain scan exhibit – so much that they are preparing a presentation to teach other students about it! It is brilliant that our way of using light to measure brain activity will be shared with 400 more students!
Café Scientifique – Henley: 21st March 2018
On a Wednesday evening in Henley, Gemma gave a talk and live demo at a local Café Scientifique to over 80 science enthusiasts. Gemma talked about near-infrared spectroscopy (NIRS), how we use light to monitor the brain and then demonstrated this live on an unsuspecting member of the audience!
With our NIRS system taped to his forehead, Gemma monitored his brain oxygenation and metabolism levels while he was doing mental arithmetic. As you can see in the picture, as his brain was working on the maths there were huge increases in his brain oxygenation to feed the increase in brain activity, as can be seen by the increase in brain metabolism! After the live demo, the audience overwhelmed Gemma with interesting questions and ideas for future experiments. Finally, Gemma ended the night by giving an overview of the research happening in the hospital to monitor brain injured babies using NIRS.
Physics in Action: November 2017 – March 2018
Our researcher, Gemma Bale, has been giving lectures across the country to inspire future physicists at Physics in Action days. Held at the University of Warwick and in London at Friend’s House and Camden Centre, Gemma has talked about her work in developing technology to monitor babies’ brains with light to over 2000 A level students! The lecture includes creating an optical model of the brain using milk and cordial, getting everyone in the audience to shine light through their hands with their phone torches and a look into the future of medical devices.
The Big Bang Fair 2018 Roundup
13th to 17th of March 2018
The MetaboLight team went to Birmingham and took on The Big Bang Fair; the largest celebration of science, technology, engineering and maths (STEM) for young people in the UK. An event with foot traffic of between 8,000 and 10,000 people each day. We were very pleased with the opportunity and we can confirm now that this event was a major, but enjoyable, challenge for the whole team.
Our interactive exhibit helped a lot in bringing in the crowds and our three main activities of (1) Guessing the gummy bear colours; (2) Making your hand invisible with near-infrared light; and (3) Measuring your brain activity; were a success. In fact, we made more than 300 hands invisible, measured the brain power of more than 300 brains and gave away more than a couple of thousand gummy bears.
One of our main activities this time was the hand scanner, a device that people place their hands in and using near-infrared light we demonstrate to them how their hand becomes invisible. This device was put together by our resident medical engineer Nico Chen using various LEDs (light sources), a very sensitive camera that can see near-infrared light and a Raspberry Pi (a small computer). It was literally a “hands on” activity illustrating how different colours of light pass through tissue and how near-infrared light can penetrate through bone. We use near-infrared light in our research to look into the brains of very sick newborns in the intensive care unit and quantify their levels of brain oxygenation and metabolism; information that medical doctors can use to treat the infants.
We would like to thank everyone that came to see us in The Big Bang Fair and importantly the people that did our activities and asked a lot of questions!
Lates: Future Science at National Science and Media Museum
Two of our MetaboLight team members went to the National Science and Media Museum in Bradford to give a talk and demonstration on how we use near-infrared spectroscopy (NIRS) to monitor the brain!
People from all across Bradford came and visited our stand, with around 200 visitors over the 3 hour demonstration period. We managed to illuminate over 20 brains, and many visitors were fully engaged and interested in our explanations on how our compact system works and how this technology is being used to save lives of babies.
Our researcher, Paola Pinti, also gave a talk describing how light interacts with the environment, and how we use its properties to monitor the brain. She also gave insights from her own research projects, and fascinated audiences with the capabilities of this technology.
It was a fun day – hopefully we inspired more people to become scientists and engineers!
Engineering Saves Lives Masterclass
Two of the Metabolight team recently hosted a session as part of UCL’s “Engineering Saves Lives” Masterclass series. Students from all across London came together to learn about how our team use light to explore the brain.
The day started with a short presentation on our work before moving on to the “science circus”. Four experiments were set up to explore different aspects of light and the brain, with students moving between experiments after ten minutes. Experiments ranged from using a model of metabolism in the brain to look at its function through to shining light through different materials to try and light up a sensor.
After a short break, students then took part in an electronic engineering tutorial led by Metabolight’s resident engineer, Nico Chen. From simple circuits that light up LEDs through to more complex ones that used different combinations of switches, all the students really enjoyed the chance to get hands on experience with part of our work that we don’t often get to talk about!
We finished the session by looking at the kind of machines we use in a clinical and research setting before then getting a few of the students up to the front to live stream their brain’s haemodynamics using our mini CYRIL device.
All in all, it was a great day with both our team and the students taking a lot away from the experience.
We’ll be posting materials about the experiments we developed for this session in the near future!
National History Museum
Our team at MetaboLight had an exciting afternoon on 9 November at the Natural History Museum where we shared our work with teachers.
The event was organized by STEM Learning and the Natural History Museum, and aimed to assist and inspire teachers in creating and delivering science to their students in fun and exciting ways.
We prepared some nice experiments that can easily be reproduced in classrooms, shining various coloured lights through different liquids to demonstrate light interaction with matter at different wavelengths. We also showed teachers how a normal smartphone can monitor heart beat rate using the same principle!
We spoke about our research work to lots of people and saw a lot of interest in our demonstrations from teachers! Hopefully we helped them to inspire their students to become scientists and engineers!
Norwich Science Festival
On 25 October, our team at MetaboLight went to Norwich Science Festival to share our work with others!
Norwich Science Festival took place over a week-long period, and we were lucky enough to be involved with this event for one of those action-packed days. With foot traffic of between 8,000 and 10,000 each day, we were in for a busy time! We got to show off our interactive exhibit that was first presented at our launch event, as well as share our work using light with the many festival-goers.
The highlight of our exhibit was using one of our compact systems to monitor brain activity. We recruited volunteers to do some mental arithmetic sums whilst we monitored their head using light. With increased brain activity, we expect to see an increase in blood flow as our brain cells need more oxygen and glucose to generate energy and we can measure this increase in oxygenated blood using near-infrared light. We saw some great results from our volunteers.
Festival organiser, Natalie Bailey, said “The footfall for the 9 days in the Forum was approx. 75,000, which just shows how much interest there is in science” and that our “stand looked fantastic and was very engaging!”
It was an eventful day – we spoke to lots of people, monitored lots of brains (over fifty) and hopefully inspired some future scientists and engineers!
