| Earth, home of human beings, is 70% water and 30% land which has nurtured splendid civilizations and flourishing lives. The cover story of this issue reflects the evolution of Earth by merging an unknown planet in a unified scene with different landscapes throughout the history such as glacier, desert, ocean, mountain, river and magma. The contrast between the past to reality can best illustrate our respect to our motherland. It is not only the subjects of geoscience studies, but also the common goal of all multidisciplinary research and the shared duties of mankind to understand, care and protect our planet to build a better future. |

Mass testing is an intervention strategy for COVID-19 control in the general population regardless of the presentation of symptoms. It involves collecting nasal or pharyngeal swabs for DNA testing, often using the polymerase chain reaction method. Countries that have used mass testing consider it to be a viable strategy to control the COVID-19 pandemic as the strategy can potentially identify and isolate asymptomatic cases in the early stages of infection and reduce the risk of virus transmission.
