Research image of the month #3: CAR 'any size' fashion shoot

Model posing at CAR any size fashion shoot

This might look an like an unlikely candidate for a Health and Life Sciences Research image - more like something from a fashion magazine. In fact it was taken during an 'any size' fashion shoot organised by researchers from the Centre for Appearance Research (CAR) in the Department of Psychology.
CAR researchers Dr Phillippa Diedrichs and Nicole Paraskeva organised the shoot to encourage the use of models with diverse body shapes and sizes in the media. They will use the photos to explore the impact of unrealistic perfected images on appearance and body image, by comparing public opinion of these photos of ‘real people’ with those of airbrushed models more often used in advertising campaigns and fashion magazines. 

Research consistently shows that viewing idealised media images has a negative impact on body image for children and adults. Exposure to ultra-thin and muscular models contributes to unrealistic beauty ideals and can seriously harm individuals’ psychological and physical wellbeing.

Speaking about the importance of the research Dr Diedrichs says: “There have been recent calls from the general public, advocacy groups and politicians for the use of models that reflect reality and have different body shapes and sizes. We hope that these photos, presenting more diverse and realistic images of beauty, will help to promote healthy body image".

Research image of the month #2: Bioluminescent bacteria

We actually have an image and a video this month, courtesy of Dr Gareth Robinson in the Department of Applied Sciences. The photo above shows a plate of glowing Pseudomonas aeruginosa bacteria viewed under a low light imaging camera for 0.5 seconds.

Bioluminescent bacteria can be used as an excellent reporter of metabolic activity and have many applications in scientific research, from checking food is heated thoroughly to testing the effectiveness of antibiotics. Dr Robinson is working with Dr Darren Reynolds, Dr Robin Thorn and PhD student Dann Turner on research that uses bioluminescent bacteria to evaluate the effectiveness of a novel disinfectant.

Speaking about the applications of bacterial bioluminescence in research at UWE Dr Robinson said, “We use the DNA from naturally occurring bioluminescent bacteria, (like those in the light organs of deep sea marine creatures), and transfer it to disease causing bacteria to make them glow. Our current research uses bioluminescent bacteria to evaluate the effectiveness of electrochemical solutions as disinfectants that could potentially be used in hospitals. If the disinfectant kills the bacteria then they stop glowing, either due to the destruction of the cell or because they stop metabolising.”

Research image of the month #1: Cell membrane 

Posted by Kathleen Steeden | 0 comments

The first in our monthly research image series is this striking picture that looks almost as though it could be the atmosphere of a distant planet. In fact it shows the inside of a cell membrane. The cell has been split apart by particle enhanced cell lysis, which involves energising paramagnetic particles (the round balls in the picture) with ultrasound energy and using them to break down cells to capture their contents.

This image is a result of UWE PhD research, which aims to develop particle enhanced cell lysis as a novel technology for rapid diagnosis.
