Adult female giraffes who spend time in larger groups with other females live longer than less sociable individuals. The effects of sociability on survival outweigh other factors such as environment or human presence, a study of giraffes in Tanzania led by the University of Zurich has shown.

Marmoset monkeys perceive the vocal interactions between their conspecifics not just as a string of calls, but as coherent conversations. They also evaluate their content.

The onset of the COVID-19 pandemic caused a sharp decline in living standards and rising food insecurity in lowand middle-income countries across the globe, according to a new study by an international team of economists including from Swiss TPH.

Scientists from the University of Geneva and UPF have analysed the skeletons of several Bronze Age communities that lived in Western Switzerland in order to reconstruct the evolution of their diet.

For his thesis project at EPFL, Armel Kemajou studied the peri-urban areas of Lomé, Togo, and Yaoundé, Cameroon, where populations are expected to double in 20 years. He observed construction strategies that reflected coherent individual and collective approaches to planning, although they lay outside existing legal frameworks. Kemajou gives proposals for incorporating such an approach to construction, parting ways with urban planning patterned on European cities, which is unsuitable for these countries.
