Social dilemmas about protective measures — ScienceDaily

We need to know about these psychological and social profiles so we can understand how protective actions against contagious diseases are adopted, and then define the correct preventive approaches. At the very start of the coronavirus crisis — before restrictive measures were taken — a team of health behaviour specialists from the University of Geneva (UNIGE) managed to collect a large amount of data about the adoption of protective measures.

They offer a tantalizing, three-dimensional look at dinosaur times. The vivid creatures and plants look like they just died yesterday with soft tissue in place and details like skin, coloring, feathers, teeth, leaves and petals exquisitely preserved — details that are often lost in the crush of fossils formed in rock.
