Social learning, a hallmark of human behavior, entails integrating other's actions or ideas with one's own. While it can accelerate the learning process by circumventing slow and costly individual trial-and-error learning, its effectiveness depends on knowing when and whose information to use. In this study, we explored how individuals use social information based on their own and others' levels of uncertainty.

Turbulent convection governs heat transport in both natural and industrial settings, yet optimizing it under extreme conditions remains a significant challenge. Traditional control strategies, such as predefined temperature modulation, struggle to achieve substantial enhancement. Here, we introduce a deep reinforcement learning (DRL) framework that autonomously discovers optimal control policies to maximize heat transfer in turbulent Rayleigh-Bénard convection.

Major depressive disorder affects millions worldwide, yet current treatments require prolonged administration. In contrast, ketamine produces rapid antidepressant effects by blocking spontaneous N-Methyl-D-Aspartate (NMDA) receptor signaling, which lifts the suppression of protein synthesis and triggers homeostatic synaptic plasticity. Here, we identify a parallel signaling pathway involving metabotropic glutamate receptor 5 (mGluR5) that promotes rapid antidepressant-like effects.

These studies examine whether expressing outrage at a prejudiced individual may undermine justice-insensitive White Americans' motivation to engage in more costly actions addressing systemic racism. Study 1 ( = 896) manipulated White privilege salience and the opportunity to express outrage before measuring donations to a racial justice organization. Reminders of racial privilege increased White collective guilt, and donations among White U.
