Full-text search Fulltext search 57 Resultate Deep learning results in particularly sexist AI systems Decisions made by machines based on AI have already been shown to be discriminatory or racist. This is due to the fact that the algorithms draw on data originating from humans, and this data is frequently biased – among other things with sexist prejudices. Converting plastic waste into fuel Scientists have developed a new method to convert plastic waste into hydrogen through pyrolysis, a high-temperature chemical process. Unused mobile phones hold huge potential The metal of discarded mobile phones in Germany is sufficient to cover the material demand for smartphones for the next ten years - purely mathematically. Empa makes eco-cement Cement production is responsible for 9 percent of carbon emissions in Switzerland. Researchers at Empa believe that this can be changed. Even cement production methods that absorb more CO₂ than they emit are on the horizon. Sahara sun from the laboratory ETH Zurich has put an artificial sun into operation. In the room of a new laboratory, the sun shines at the push of a button, just as it does at midday in the Sahara or in January in Berlin. Sensors and switches made of wood Sustainable electronic elements can be made from wood. This is helped by a novel process that uses a laser to engrave electrically conductive tracks into veneers. An opportunity for sustainable urban development Viennese complexity researchers have found a method to predict the growth of cities. This could facilitate much more efficient urban development and help conserve resources. Electricity from chicken feathers Researchers want to use chicken feathers to produce green electricity. They use the keratin in chicken feathers to replace highly toxic chemicals in fuel cells. World record for tandem solar cells A Swiss research team has succeeded in increasing the efficiency of perovskite silicon tandem solar cells to over 30 percent. This is a world record.
