Intestinal Clock Promotes Cognitive Memory Through Adenosine Signaling

open access: yesAdvanced Science, EarlyView.
The intestinal clock controls the expression of an adenosine enzyme that modulates systemic adenosine level and A1R signaling in the hippocampus, and in turn, cognitive function involving long‐term potentiation and BDNF‐dependent synaptic changes.

An Amygdala‐hippocampus Circuit for Endocannabinoid Modulation of Anxiety Avoidance

open access: yesAdvanced Science, EarlyView.
This study employs three synapse‐specific endocannabinoids (eCB) probes to monitor dynamic eCB release, activate CB1Rs and knockdown 2‐AG biosynthesis enzymes in glutamatergic anterior basolateral amygdala ‐ ventral hippocampus (aBLA–vHPC) circuit. At aBLA–vHPC circuits, activation of CB1Rs reduce anxiety avoidance, and knockdown of eCB biosynthesis ...

Born to Fear the Machine? Genetic and Environmental Influences on Negative Attitudes toward AI Agents

open access: yesAdvanced Science, EarlyView.
Why do some people fear or distrust AI agents more than others? This twin study shows that negative attitudes toward AI may partly stem from genetic factors, linking them to traits like victim sensitivity and moral beliefs. These findings show that it is not only nurture but also nature that shapes our views of AI, with implications for future human–AI

Plasmon‐Driven Nitrogen Photoreduction to Ammonia Using Silica‐Encapsulated Au Nanostar/TiO2 Nanohybrids

open access: yesAdvanced Energy Materials, EarlyView.
Photocatalytic N₂ reduction is a sustainable method for ammonia production. Au nanostars (AuNST) with TiO2 excel, especially when encased in mesoporous silica, enhancing stability and selectivity without scavengers. Electromagnetic fields at nanostar spikes drive hot‐electron transfer to TiO2 for N2 reduction under visible light, while hot holes ...
