Measures to contain the Corona pandemic are the subject of politically charged debate and tend to polarize segments of the population. Those who support the measures motivate their acquaintances to follow the rules, while those who oppose them call for resistance in social media. But how exactly do politicization and social mobilization affect the incidence of infection? Researchers at the Max Planck Institute for Human Development have examined this question using the USA as an example. Their findings were published in
Applied Network Science.

Growing cities tend to follow a universal pathway, moving from work that relies primarily on manual labor to jobs that rely more heavily on cognitive labor, the researchers report. In a study of U.S. urban areas, the team found that the tipping point tended to occur when the population reached about 1.2 million. Small cities under that threshold may not be able to build a strong tech industry because they don’t have enough people in othe
