Folic-acid-functionalized Fe3O4@C@Pt nanozyme for synergistic catalytic-photothermal tumor therapy† Nanozymes are enzyme-like nanomaterials that have attracted considerable interest because of their high stability, ease of preparation, and tunable catalytic performance, particularly in cancer treatment. However, ineffective accumulation of nanozymes at tumor sites results in low catalytic therapeutic efficiency and even affects synergistic therapy.

The global pandemic brought unprecedented challenges and changes to societies worldwide. Beyond the immediate health crisis, there was a significant impact on our social lives. One area of concern was whether the heightened risk of infectious diseases would lead to increased xenophobia—fear or hatred of foreigners and immigrants. A popular hypothesis from the behavioral immune system literature said yes. It suggests that negative attitudes toward outgroups serve pathogen-neutralizing functions.

1 Introduction Tropical biomes hold the Earth's largest carbon pool (Chen et al., 2017; Pan et al., 2011; Wigneron et al., 2024), especially for tropical forests accounting for approximately half of the global gross primary production (GPP) (Wang et al., 2024). Slight fluctuations of tropical forest growth and mortality could profoundly impact the global carbon balance, and even exacerbate the rise in atmospheric CO2 concentrations (Espirito-Santo et al., 2014).

AbstractTropical terrestrial ecosystems play an important role in modulating the global carbon balance. However, the complex dynamics and factors controlling tropical aboveground live biomass carbon (AGC) are not fully understood. Here, using remotely sensed observations, we find a moderate net AGC sink of 0.21 ± 0.06 PgC yr−1 throughout the global tropics from 2010 to 2020. This arises from a gross loss of −1.79 PgC yr−1 offset by a marked gain of 2.01 ± 0.06 PgC yr−1.
