Analyzing the micromovements of recovering alcoholics in response to stimuli, along with their reaction times, might help predict if they will relapse following treatment

A new MOF-coated catalyst creates a local reaction environment, concentrating CO2 near copper single-atom reaction sites and enhancing CO conversion. The catalyst produces CO at approximately five times the rate of pristine BaTiO3 under ultrasonic vibration.

Depression alters neural circuits in the amygdala, leading to reduced activity in pleasant stimuli and increased activation in negative stimuli. This negativity bias contributes to depressive symptoms. Researchers found a potential treatment by reactivating neurons involved in positive encoding of environmental stimuli.

The human brain can learn to suppress early visual processing of distracting stimuli, such as roadside billboards, after repeated exposure. This learned suppression enhances attention to relevant stimuli and improves performance in tasks that involve frequent distractions.

The study identifies the brain circuit controlling associations between stimuli and allows for indirect associations. The amygdala plays a crucial role in linking olfactory and taste stimuli.

Researchers visualized the dynamic shuttling of α-CD rings along a PEG chain in real time, revealing localized structural changes. The study introduces a new method for analyzing supramolecular polymers and could pave the way for energy-efficient molecular motors.

A new theory predicts that a layer of mostly product at the interface determines the reaction rate in mechanochemical reactions. The force applied by the balls accelerates the reaction by reducing the thickness of the product-rich layer and inducing faster collisions between reactants.
