The number of young people living with serious, incurable bowel conditions is rising globally, but new scientific tools may offer hope for better understanding and treatment. In the UK alone, more than half a million people are affected by inflammatory bowel disease (IBD), which includes two main conditions: Crohn’s disease and ulcerative colitis. These diseases typically strike between the ages of 15 and 40, a time when people are building their careers and personal lives, making the impact of the illness particularly profound. Researchers at the Rosalind Franklin Institute in Oxfordshire are working on a groundbreaking microscope that could help unlock new insights into IBD and other diseases. Dr. Karina Pombo-Garcia, a group leader at the institute, explained that while some treatments exist, they may not be the most effective because scientists still don’t fully understand the mechanisms behind these conditions. The microscope, nicknamed "Curie," uses a cutting-edge technique called stimulated emission depletion (STED) microscopy, which was awarded a Nobel Prize in Physics in 2014. This method allows researchers to see cellular structures as small as 20 nanometers, far beyond the resolution of conventional microscopes. The microscope’s unique design includes deformable mirrors that correct optical distortions and a temperature-controlled stage, allowing researchers to study living cells and mini-organs under conditions that closely mimic the human body. PhD student Dimitrios Ioannidis is using the microscope to study how cells in the intestines form protective barriers. By observing changes in protein structures from fetal development to adulthood, he hopes to uncover how these changes might contribute to diseases like IBD. "If the structure changes, so does the function," he explained, noting that comparing healthy and diseased tissue could reveal the root causes of these conditions. The microscope was recently unveiled by science minister Chris McDonald, alongside a major funding boost for the Rosalind Franklin Institute and the Henry Royce Institute. However, the broader UK science sector is facing financial challenges, with some national facilities at risk due to rising costs and budget constraints. Despite these concerns, McDonald emphasized that while funding decisions must be made carefully, the UK remains committed to supporting scientific research and innovation.
