New findings explain why treatment for this arterial occlusive disease often fails to produce the desired results: the problem of vascular disease lies not only in the main arteries of the legs, but also in the smallest blood vessels and surrounding muscle cells.
AI models and the data centres behind them consume a lot of energy, raising sustainability concerns. In an interview, Ana Klimovic, ETH Zurich professor and expert in sustainable machine learning, explains how AI computing can become more efficient – starting with smarter GPU use.
Urban trees are often seen as natural allies in fighting summer heat waves. But how much they actually help to cool their surroundings depends heavily on how moist the soil is. This is the main finding of a new study, led by environmental engineers at ETH Zurich and Eawag.
