In freezing weather, ice causes many a traveller to come unstuck. But as experimental physicist Robin Ras explains, getting to grips with what makes ice so slippery isn’t easy. Whether you’re gliding serenely across an ice rink, or awkwardly down a footpath, the frictionless surface offered by ice can often be surprising. What makes it […]
Machine learning unlocks ice core climate clues
A new technique based on machine learning can help scientists to more efficiently analyse ice cores. This could unlock new clues about our climatic past. Ice cores – long cylinders of ice drilled and extracted from polar ice sheets or alpine glaciers – provide pristine records of past climates. Layers of deposit create a succession […]
