“We have to ask some uncomfortable questions”
All human activities affect the landscape and ecology, even if we stop using nuclear energy and rely on renewable energy. Astrid Björnsen led the joint Energy Change Impact research programme of WSL and Eawag. It provides accurate data on the potential and availability of renewable energy in the country.

No room for discrimination or harassment
Discrimination and harassment violate scientific integrity – but the damage they do goes beyond that. According to Janet Hering, director at Eawag and professor at ETH Zurich, they also represent a waste of resources including energy, talent, finances, reputation and culture.

Better choice of contraceptives can prevent breast cancer
There is a strong link between hormonal contraceptives and breast cancer risk. An EPFL study into the distinct biological effects of different progestins shows that contraceptive-related breast cancer can be prevented by more informed choices about the composition of contraceptives.

 Reforestation projects are a well-​known facet of restoration, but ecological restoration takes many forms. (Photograph: Simeon Max, Restor AG)
A social network for global ecosystem restoration
ETH spin-off Restor aims to increase the success rate of ecosystem restoration and conservation projects by connecting people with better data and ecological transparency. To do this, it combines practical knowledge on the ground with data from ecosystem researchers and satellite imagery.

 Skyrmions are nanostructures: tiny eddies in the magnetic alignment of atoms. PSI researchers have created so-called antiferromagnetic skyrmions for the first time. In them, critical spins are aligned in opposite directions. Here is an artist's rendering of this condition. (Graphics: Paul Scherrer Institute/Mahir Dzambegovic)
Magnetic nanoworld
At PSI, researchers are studying magnetism in the range of a millionth of a millimetre. In doing so, they come across exotic phenomena such as frustrated magnets and nano-vortices, which may one day enable better data storage.
