Almost 100 billion tons of CO₂ could be pulled out of the atmosphere by the end of the century. That is, if high-income countries switch to a plant-based diet. The double carbon profit of returning farmland to its natural state would equal about 14 years’ worth of agricultural emissions, researchers…

Farmers do not love them all. Microbes can cause tragic consequences for crops. Even the presence of just one pathogenic fungus or bacterium can drastically reduce yields. Still, there are exceptions. In that case, a pathogenic microbe is present in the soil, but does not cause any harm. Adam Ossowicki…

‘Archeologists don’t dig up explanations, let alone certainties,’ says Joanita Vroom, Professor of Archaeology of Medieval and Early Modern Eurasia. ‘Their job is to bridge the gap between the sherds that they find and people’s everyday lives. What do ceramics from the past say about people’s eating…
