Elephants rarely get cancer: less than 5% of captive elephants die of cancer, compared to 20% of humans. Elephant genomes have at least 20 copies of the tumour suppressor, p53, which may explain their low cancer rates relative to humans, who have only one copy.
My name is Joanna and I’m a second year Engineering student at Murray Edwards College. I’ve always been interested in science, and as years progressed I found myself unable to choose just one narrow discipline. I decided studying Engineering will teach me how to apply a wide range of knowledge to everyday concepts. This was also why the engineering course at Cambridge was especially interesting to me, as its open structure with general engineering taught during the first two years allowed me to further explore different areas before deciding which one is the most fulfilling for me.
I remember being a little apprehensive about my own abilities in a technical field before I started my degree. While taking part in a Physics Olympiad in my home country I met boys who made robots with their fathers ever since a young age, and were taking apart computers for fun (I was the only girl in the national finals, as well!). My high school didn’t even have a laboratory and if I took apart one of our home appliances my mother would never forgive me. I wondered, would I ever be able to create something myself? Could I ever compete with them? And then the Cambridge course started and I got my answer – yes! Thankfully, it seems the university believed in me more than I believed in myself.
In the very first week we were asked to build robots from Lego Mindstorms. I still remember it as a week of absolute panic and despair – but also utter delight when at the end of it our robot was actually moving and doing what we wanted it to. Not long after that we were asked to build an AM radio using a bunch of wires, capacitors, resistors and our knowledge of circuits. (In the photo at the top you can see me, excited, with the ready “product”.) This year, we were asked to build a robot again. In groups of 6, in the space of a month, we created, almost from scratch, an actual moving thing that could follow lines, pick up multi-coloured sticks and sort them into boxes scattered around a playing area. I was responsible for the electrical systems on the robot, such as light sensors, PCB boards and actuators. Interestingly, considering my initial apprehension, those hands-on activities became the most enjoyable part of my degree. This is why I applied to the Cambridge-MIT exchange scheme, and from September will be studying at the top Technology Institute in the USA, known for its hands-on approach and dedication to research. The research aspect is especially interesting for me. In the next two years I want to specialize in Electrical and Information Engineering and hope to one day be able to contribute to the development of electronic devices.
