When wind blows over dry snow, the snow surface self-organizes into bedforms such as dunes, ripples, snow waves, and sastrugi.These bedforms govern the interaction between wind, heat, and the snowpack, but thus far they have attracted few scientific studies.We present the first time-lapse documentation of snow bedform movement and evolution, as par

Background Reduced hip adduction strength has been identified as a key predisposing factor in developing hip and groin injuries.The Copenhagen adduction programme has been shown to increase hip adduction strength in semiprofessional footballers but can cause muscle soreness.Therefore, a modified progressive Copenhagen adduction (MPCA) programme has
