Chaos, complexity and computation are especially important concepts with respect to both the Evolution of biological systems and the evolution of the Universe. We consider each of these five entities separately, and then view their combination in an overall consideration of both evolution and Evolution. The concept of computation can be directly derived from processes characteristic of the Evolution of biology or the evolution of the Universe, rather than presumed from our own mathematical ideas. We advocate the inclusion of meaning in science's deliberations, and support this by insisting that physically embodied abstractions should be considered part concrete in character. Combination of our initial five conceptual entities indicates that biological Evolution follows the same developmental criteria as the evolution of the Universe, albeit with an intermediate change in strategy. We conclude that evolutionarily derived computation is the prime driver of evolution/Evolutions' implications.

Social learning plays an essential role in all cultural processes, but the factors underlying its evolution remain poorly understood. To understand how socio-ecological conditions affect social learning, we compared peering behavior (i.e.

Solar-driven, selective biomass hydrogenation is recognized as a promising route to renewable chemicals production, but remains challenging. Here, we report a TiO supported Cu single-atom catalyst with a four-coordinated Cu-O structure, which can be universally applied for solar-driven production of various renewable chemicals from lignocellulosic biomass-derived platform molecules with good yields using green methanol as a hydrogen donor, to address this challenge. It is significant that the biomass upgrading driven by natural sunlight on a gram scale demonstrates the great practical potential.

The bifunctional mechanism, involving multiactive compositions to simultaneously dissociate water molecules and optimize intermediate adsorption, has been widely used in the design of catalysts to boost water electrolysis for sustainable hydrogen energy production but remains debatable due to difficulties in accurately identifying the reaction process. Here, we proposed the concept of well-defined Lewis pairs in single-atom catalysts, with a unique acid-base nature, to comprehensively understand the exact role of multiactive compositions in an alkaline hydrogen evolution reaction. By facilely adjusting active moieties, the induced synergistic effect between Lewis pairs (M-P/S/Cr pairs, M = Ru, Ir, Pt) can significantly facilitate the cleavage of the H-OH bond and accelerate the removal of intermediates, thereby switching the rate-determining step from the Volmer step to the Heyrovsky step.

The pursuit of obtaining enzymes with high activity and stability remains a grail in enzyme evolution due to the stability-activity trade-off. Here, we develop an isothermal compressibility-assisted dynamic squeezing index perturbation engineering (iCASE) strategy to construct hierarchical modular networks for enzymes of varying complexity. Molecular mechanism analysis elucidates that the peak of adaptive evolution is reached through a structural response mechanism among variants.

Background/objectives: Hematopoietic cell transplantation (HCT) is a curative treatment for various hematological diseases but can lead to complications which increase malnutrition risk, particularly in allogeneic transplantation patients. This study evaluates the nutritional status evolution of patients undergoing HCT during hospitalization and follow-up.
Methods: This retrospective observational study included 365 patients, divided into two groups: 134 underwent allogeneic HCT, while 231 underwent autologous transplantation or CAR-T therapy.
