This study found that emotional awareness relies on general cognitive processes, like reflective thinking, rather than just specialized emotional mechanisms. The research suggests that the ability to understand emotions is learned and linked to the habit of engaging in thoughtful, reflective cognition.

This study used Fitbit data from 113 participants to explore how different types of physical activity relate to memory and mental well-being. The results suggest that certain forms of exercise are linked to specific cognitive and mental health outcomes. While the study found correlations, it doesn't establish cause and effect, leaving room for further research on how exercise influences brain health.

This global study found that societal pressure to be happy is linked to poorer well-being, especially in countries with higher levels of reported happiness. The findings suggest that overemphasizing positivity can negatively affect individuals, particularly in societies where happiness is seen as a social norm.

This study found that single measurements of THC in blood or breath don’t reliably indicate impairment, especially in chronic cannabis users. Researchers suggest that other cannabinoids in exhaled breath may better signal recent cannabis use and impairment, raising concerns about the accuracy of current THC limits for driving.

This study examined how methamphetamine impacts brain cells in the dorsomedial striatum (DMS), a region linked to goal-directed behavior in mice. Researchers found that meth altered the excitability of specific neurons in the DMS during abstinence, which may contribute to negative emotions and drug-seeking behaviors. These findings highlight the need for further research on how meth affects brain function and behavior over time.

This study found that over 20% of Michigan’s population identifies as childfree, meaning they chose not to have children, often deciding early in life. The research also reveals some tension between parents and childfree adults, with each group showing favoritism toward their own. The findings highlight the importance of recognizing the experiences and needs of childfree adults.

This study found that injecting the SARS-CoV-2 spike protein into the hippocampus of mice caused memory problems and anxiety-like behavior. The spike protein didn’t kill neurons but activated glial cells to release inflammatory molecules. These findings may explain some of the neurological and psychological symptoms seen in COVID-19 patients.

This study compared reading on smartphones to reading on paper and found that smartphone use led to fewer sighs, more brain activity, and lower reading comprehension. Researchers suggest that blue light from phones may increase cognitive load and attention, affecting brain function and comprehension.

This study analyzed data from over 10,000 children in the US to explore how different types of screen time affect intelligence. Researchers found that gaming had a positive impact on children's intelligence over two years, while watching videos had a smaller but still positive effect. These findings shed light on the potential cognitive benefits of digital media use.

This study explored how urban traffic noise and birdsong affect mood and cognitive performance. Results showed that listening to birdsong reduced anxiety and paranoia, while traffic noise increased depression. Interestingly, neither soundscape affected cognitive performance. The findings suggest birdsong could help improve mental well-being.
