The physics of biofilms and ice cream

Cait Macphee

MSc Science Communication and Public Engagement students Anna Purdue, Hanyue Sun and Jiazhuo Lin  interviewed School of Physics and Astronomy researcher Prof Cait MacPhee.

Tell us about your research. How does it link to ice cream?

We are studying a biofilm formed by a very common microbe called Bacillus subtilis. We’re interested in the fact that it’s basically waterproof. We discovered the protein that makes this biofilm water repellent, and it does this by going to an interface between liquid and air and forming a film. Ice cream contains air bubbles which make it lighter and easier to scoop.  It also contains oil (fat) and ice crystals. The protein we found goes to the surface of the ice crystals, the surface of the air bubbles and the surface of the oil droplets and stabilises all of them. By doing this you can slow the melting down of the ice cream! Continue reading “The physics of biofilms and ice cream”

Industrial collaborations and problem solving

Reseacher Susana Direito

MSc Science Communication and Public Engagement students Anna Purdue, Hanyue Sun and Jiazhuo Lin visited us recently and interviewed School of Physics and Astronomy Dr Susana Direito about her research and industrial collaborations.

Tell us about your research

I have been working with Edinburgh Complex Fluids Partnership (ECFP) for three years, and have also been a researcher for the National Biofilms Innovation Center (NBIC) for two years. I am a bit different from the other researchers because my main focus is based on industrial projects. Companies will come to us with a problem and we will try to solve it, so it works a bit like a consultancy. Continue reading “Industrial collaborations and problem solving”

Are you tempted to teach?

Find out about year 3 student Maxim Oweyssi’s experience undertaking a teach physics internship in London through The Ogden Trust.

As far as my internship goes, if someone asked me a few years ago, whether I see myself teaching children, my answer would be a decisive no: “because I want to do research” I would say. However, after having the chance to prepare and teach lessons on my own, I have to admit that there is something intriguing about the prospect of becoming a teacher. Putting aside the altruistic aspect of contributing towards the knowledge of future generations, I found the actual work fulfilling. There is something immensely satisfying about that “aha” moment when your students finally understand a new concept – they have that Archimedean eureka look in their eyes.
