A Cell Press partner journal
See the unseen. Change the unchanged.
The Innovation ¡ª published by Cell Press in partnership with members of the Youth
Innovation Promotion Association (YIPA),a part of the Chinese Academy of
Sciences¡ªis a new broad-scope, open access journal publishing basic and applied
research that has impact for the benefit of society.
On the cover: The rising in the popularity of big data, artificial intelligence, and simulation technologies has opened up new opportunities for the development of our society. The close integration of real and artificial societies has become a trend, bringing in novel concepts such as parallel society and metaverse. The artificial society system describes, predicts, and guides the real society system, in a closed-loop, iterative, and spiral-rising way, forming a new mode of social operation driven by Data-AI-Simulation techniques. In the future, with the further development of interdisciplinary cooperation and the continuous advancement of technologies, living in metaverse is within reach.

Lubrication models of cartilage, and hydrogel inspired by it


In nature, when two solid interfaces contact and slide with each other, adverse friction and wear ensue. Lubrication is an important means to reduce them. Fluid film lubrication and boundary lubrication are the most typical lubrication paradigms that are different in the principle of formation.1 More generally, in fluid film lubrication mode, the two sliding surfaces are completely separated by a fluid film with a thickness much larger than the surface asperities. At this time, the energy dissipation is mainly caused by the fluid being sheared.
