Disconnecting hepatic vagus nerve restores balance to liver and brain circadian clocks, reducing overeating in mice

Researchers found that disrupting the hepatic vagus nerve restored balance to both liver and brain circadian clocks, leading to reduced overeating behavior in mice. Severing the nerve alleviated overeating caused by deleted clock genes, suggesting a key role for this neural link in obesity.

Exercise programs help cut new mums’ ‘baby blues’ severity and major depression risk

A pooled data analysis of 35 studies found that exercise-only interventions reduced the severity of depression and anxiety after giving birth, with a significant reduction in postpartum depression risk. The minimum threshold for achieving effects was at least 80 weekly minutes of moderate intensity exercise.

What makes human culture unique?

Researchers propose that human culture is uniquely open-ended, enabling humans to communicate and understand an infinite number of possibilities. This contrasts with animal cultures, which have constraints that limit their evolution and development. By comparing human cultures with those of other species, including animals and non-huma...

Lurie Children’s study to link genetics and long-term cardiorespiratory outcomes of children born prematurely for more precise diagnosis and treatment

A new NIH-funded study at Ann & Robert H Lurie Children's Hospital of Chicago will use AI to identify disease subtypes based on genetic data and associated outcomes in premature infants. The four-year study aims to establish disease subtypes that can predict longer-term cardiorespiratory outcomes, enabling earlier interventions.

GIST scientists unveil strategies to make self-driven vehicles passenger-friendly

Researchers developed a multimodal dataset, TimelyTale, to gather passenger-specific sensor data for context-relevant explanations. The approach effectively identified the timing and frequency of passenger demands for explanations, enabling the creation of a machine-learning model to predict the best time for providing an explanation.
