We were once again well-represented in the Falling Walls Lab Slovakia 2024 finals. Three of our PhD students presented their innovative ideas to the expert committee. Alena Potočárová presented an idea with the support of data from the use of human DNA monitoring in wastewater, Kristína Lichá focused on extracellular vesicles as carriers of mitochondrial DNA in biomedicine, and Emil Bečka presented a different perspective on solving the infection of trauma patients.
