TL;DR: C climatic, biological, and geochemical signatures of human activity in sediments and ice cores, Combined with deposits of new materials and radionuclides, as well as human-caused modification of sedimentary processes, the Anthropocene stands alone stratigraphically as a new epoch beginning sometime in the mid–20th century.

TL;DR: The Anthropocene is a reminder that the Holocene, during which complex human societies have developed, has been a stable, accommodating environment and is the only state of the Earth System that the authors know for sure can support contemporary society.

TL;DR: In this article , a new SARS-CoV-2 viral isolate Omicron-B.1.529 was announced, containing far more mutations in Spike (S) than previously reported variants, leading to a large number of mutations in the ACE2 binding site and rebalances receptor affinity to that of earlier pandemic viruses.

TL;DR: The term Anthropocene has been proposed and increasingly employed to denote the current interval of anthropogenic global environmental change as mentioned in this paper, which is considered as a formal epoch in that, since the start of the Industrial Revolution, Earth has endured changes sufficient to leave a global stratigraphic signature distinct from that of the Holocene or of previous Pleistocene interglacial phases, encompassing novel biotic, sedimentary and geochemical change.

TL;DR: The Anthropocene, following the lost world of the Holocene, holds challenges for both science and society as mentioned in this paper, and the challenges of the Anthropocene can be summarized as follows:
