    Children with Cerebral Palsy (CP) can generally not walk unaided, but do have some weight bearing ability. Therefore walking aids are often more appropriate than wheelchairs, see figure 1. These devices facilitate mobility and also provide vital mechanical stimulation of the lower limbs [1]. However, existing designs show little evidence of being optimized for ergonomics and biomechanical function, let alone aesthetics. A current collaboration between Moorings Mediquip (Northern Ireland) and Trinity College Dublin funded by an Intertrade Ireland Fusion grant is concerned with developing a new gait trainer for children with CP which has improved functionality and aesthetic features compared to existing products

    Microplastic interactions with north atlantic mesopelagic fish

    Microplastics in the marine environment are well documented, and interactions with marine biota have been described worldwide. However, interactions with vertically migrating fish are poorly understood. The diel vertical migration of mesopelagic fish represents one, if not the largest, vertical migration of biomass on the planet, and is thus an important link between the euphotic zone, transporting carbon and other nutrients to global deep sea communities. Knowledge of how mesopelagic fish interact and distribute plastic as a marine contaminant is required as these populations have been identified as a potential global industrial fishery for fishmeal production. Ingestion of microplastic by mesopelagic fish in the Northeast Atlantic was studied. Approximately 11% of the 761 fish examined had microplastics present in their digestive tracts. No clear difference in ingestion frequency was identified between species, location, migration behaviour, or time of capture. While ingesting microplastic may not negatively impact individual mesopelagic fish, the movement of mesopelagic fish from the euphotic zone to deeper waters could mediate transfer of microplastics to otherwise unexposed species and regions of the world\u27s oceans
