Social media have become an integral part of everyday life. However, numerous studies have produced conflicting results on how the use of these applications affects the mental health of their users. A common assumption is that the use of many different social media platforms has a negative impact on users‘ well-being. Researchers Sophie Lohmann and Emilio Zagheni, Director of the Max Planck Institute for Demographic Research (MPIDR) in Rostock, Germany, investigated this assumption. In their study, they used a statistical technique to adjust for the fact that people who use a number of social media platforms may be different to start with. The result of the study shows that the use of many different social media platforms is not a significant risk factor for the well-being of the users.
In essence, we reweighted the sample and simulated that each participant had the same

As scientists from the Max Planck Institute for Dynamics of Complex Technical Sys-tems in Magdeburg and the Technical University of Ilmenau have calculated, contact restrictions that prevent overloading intensive care units are more likely to be lifted if younger people are vaccinated first given an observation period of more than eight weeks.
At the same time, the Israeli government is again imposing contact restrictions.
