Half of the population of Geneva have antibodies that neutralize the Omicron variants
A study by the HUG, the UNIGE and the EPFL shows that almost all Genevans (93.8%) have antibodies against SARS-CoV 2 but less than one in two (46.7%) have them against the BA.4/BA. Omicron sub-variants. A study by the Geneva University Hospitals (HUG), the Faculty of Medicine of the University of Geneva and the EPFL shows that almost all Genevans (93.8%) have antibodies against SARS-CoV 2, almost three quarters of whom acquired them through an infection.

Don't attack the Energy Strategy with simplified assumptions
Don’t attack the Energy Strategy with simplified assumptions
An ETH risk researcher has concluded that Energy Strategy 2050 doesn't work. The Energy Science Center at ETH Zurich disagrees: extensive research shows that the energy transition is feasible and makes sense, writes Gabriela Hug together with her ESC colleagues. Earlier this month, the Neue Zürcher Zeitung newspaper reported that huge dependence on electricity imports in winter was imminent if the Swiss federal government went through with the Energy Strategy including nuclear phase-out.
