Climate protection in a ball bearing
They don’t take center stage, but they keep the world moving: bearings are technical components without which no car could drive and no wind turbine could turn. They are built into machines millions of times over. That’s why they hold great potential for climate protection. Researchers are showing how reducing friction in bearings could lower CO₂ emissions.

Quantum mysteries, real-world technology
Will quantum effects soon make our lives faster and better – or are many of the promises still just science fiction?How can we even begin to imagine quantum phenomena, given that the behavior of the tiniest particles involved is so difficult to grasp? Physics professor Artur Widera explains the fundamental laws and significance of the quantum world.
