Artificial intelligence and machine learning are key technologies for science, business, and society – but how transparent are their decisions? Andreas Krause, the 2021 recipient of the Rössler Prize and Chair of the ETH AI Center, shares his thoughts on the opportunities and challenges with trustworthy artificial intelligence.

How do you teach machines to learn for themselves and support people? Andreas Krause is one of Europe’s leading machine learning researchers. His approaches combine mathematical elegance with a sense of social responsibility. He has now been awarded the Rössler Prize, ETH Zurich’s most generous research award.

Under the motto “Ecosystem Restoration”, the theme of Word Environment Day on 5 June 2021 is the restoration of the planet’s ecosystem. The only way to achieve this is through climate protection – one of the most hotly debated topics of our time. It is becoming increasingly obvious that this not only requires a drastic reduction in greenhouse gas emissions, but additional measures for reducing the level of carbon dioxide (CO₂) in the atmosphere. Unless this happens, it will be impossible to achieve the primary goal of the Paris agreement: to restrict global warming to no more than two degrees.

Researchers at ETH Zurich have succeeded in turning specially prepared graphene flakes either into insulators or into superconductors by applying an electric voltage. This technique even works locally, meaning that in the same graphene flake regions with completely different physical properties can be realized side by side.
