Niko Beerenwinkel, a Professor at the Department of Biosystems Science and Engineering at ETH Zurich in Basel, is working with colleagues from other research institutions to examine wastewater for traces of the coronavirus. He has detected the Delta variant in five out of six Swiss wastewater treatment plants examined, including ones in Zurich and Bern. Recently he spoke with ETH News.

Is natural always good and artificial always bad? We talked to psychologist Angela Bearth and biotechnologist Sven Panke about science, scepticism, misunderstandings and how language influences the way we think.

Researchers at ETH Zurich have recreated a key step in the evolutionary history of viruses in a laboratory experiment. They succeeded in remodeling a natural protein to create capsids capable of storing genetic material.

There is a strong link between hormonal contraceptives and breast cancer risk. The main culprit are progestins, synthetic mimics of the pregnancy hormone progesterone that stimulate cell growth in the breast. An EPFL study into the distinct biological effects of different progestins on the breast shows that contraceptive-related breast cancer can be prevented by more informed choices about the composition of contraceptives.
