  • Learning to make a Magic 8 Ball

During my summer holidays, I was fortunate to spend a fantastic week at UCL’s Aspire CREATE labs at the Royal National Orthopaedic Hospital. I was able to talk and learn from all of the PhD and master’s students about their projects.

Highlights include observing a neuroscience experiment, seeing an exoskeleton and using a smart wheelchair.

I was also able to work on a project of my own. Having been given an Arduino kit at the start of the week, I had to understand how the system worked to complete a small project. 

An Arduino is a single board microcontroller - simpler than a Raspberry Pi. Having only used Arduino kits once or twice before, I found it challenging at first, but with help from my mentor Tijana I soon began to make sense of the programming language and how to build the circuits.

By the end of the week I was able to build a Magic 8 ball using an LCD screen and a tilt switch. I subsequently used an Arduino kit to build an autonomous car that is able to detect obstacles and avoid them!

Persuaded me to take science A levels

The week in the labs was incredibly useful for me, as it helped me confirm my A-level choices and it also gave me a taste of what research is like.

As a result of my work experience, I am now studying Chemistry, Biology, Maths A-level and Further Maths AS at Stowe School and I have developed a keen interest in neuroscience and biochemistry.

I hope to study Natural Sciences at university and perhaps pursue a career in research.

Overall, I thoroughly enjoyed my time with the Aspire CREATe team and would like to thank everybody there for their warm welcome and hospitality. It was a fantastic experience, and I would highly recommend it to anybody remotely interested in science. 

I was always interested in science. However, seeing the incredible application and use of scientific principles in everyday life persuaded me into taking science A-levels, a decision I have not regretted.

Groundbreaking bowel cancer trial follow-up shows zero relapses

Patients with a specific bowel cancer who were given short-course immunotherapy before surgery, instead of post-op chemotherapy, remained cancer-free after nearly three years of follow-up.

Drug to treat aggressive leukaemia approved for use in adults

Adult patients with aggressive leukaemia will soon be able to receive a breakthrough immunotherapy, developed by UCL researchers, on the NHS after approval by NICE.

Millions could benefit from faster prostate cancer scan

Results of the PRIME trial involving UCL Medical Sciences researchers have found that a quicker, cheaper MRI scan was just as accurate at diagnosing prostate cancer as the current 30-40 minute scan.
