Because of their unique physical and chemical properties, Rare earth elements (REEs) perform important functions in our everyday lives, with use in a range of products. Recently, the study of China’s rare earth elements production has become a hot topic of worldwide interest, because of its dominant position in global rare earth elements supply, and an increasing demand for rare earth elements ...

Despite the predominance of aquatic environments on the planet Earth, microbial abundance and diversity within soil environments exceed that of the aquatic realm. Most of what we know of viral ecology within natural systems has come through investigations of aquatic environments. However, the 'aquatic-bias' in viral ecology is beginning to change as the cultivation-independent approaches, which...
