May 13, 2024 Suddenly they appear and -- like the SARS-CoV-2 coronavirus -- can trigger major epidemics: Viruses that nobody had on their radar. They are not really new, but they have changed genetically. In particular, the exchange of genetic material between different virus species can lead to the sudden emergence of threatening pathogens with significantly altered ...

May 13, 2024 The researchers found that birds were more evolutionarily similar on smaller, more isolated islands than on larger, less remote places. The team had expected to find that forested areas had more numerous and more varied species of birds compared to farmland areas. But they were surprised to find that the opposite was true: Areas with farms and human settlements had more species of birds and ...

May 13, 2024 Coal phase-out is necessary to solve climate change, but can have negative impacts on workers and local communities dependent on coal for their livelihoods. Researchers have studied government plans for coal phase-out around the world and discovered that more than half of such plans include monetary compensation to affected parties. This planned compensation globally amounts to USD 200 billion, ...

May 9, 2024 A new model for predicting the effects of climate change on malaria transmission in Africa could lead to more targeted interventions to control the disease according to a new study. Previous methods have used rainfall totals to indicate the presence of surface water suitable for breeding mosquitoes, but the new research used several climatic and hydrological models to include real-world processes ...

May 8, 2024 Ancient, expansive tracts of continental crust called cratons have helped keep Earth's continents stable for billions of years, even as landmasses shift, mountains rise and oceans form. A new mechanism may explain how the cratons formed some 3 billion years ago, an enduring question in the study of Earth's ...
