Abstract

The Front Cover illustrates that by paw-holding, wild sea otters ensure they stay together and do not drift apart in their sleep. This comes from a concept of no herd member being left behind. If the experimental conditions are met, the same phenomenon is observed in the study by Renaud Blaise Jolivet and co-workers, where K⁺ ions and cage molecules interact in the solution, forming species with significantly higher Xe encapsulation rates. The preferential caging of Xe by CB[6]-alkali pairs is seen as an analogy to the paw-holding-based social gathering of sea otters. For more details, see the Research Article by Renaud Blaise Jolivet and co-workers (DOI: 10.1002/cmtd.202400033).
