A recent study examines how the structure of social networks influences the spread of both diseases and ideas, using data collected during the COVID-19 pandemic. Researchers developed a model to analyze not only social connections but also the mechanisms driving contagion and information diffusion.
Researchers have discovered that psilocybin, a psychedelic compound in magic mushrooms, increases optimism and motivation in rats, suggesting potential therapeutic benefits for treating depression. Using computational modeling, scientists observed that rats given psilocybin were more likely to engage in reward-based tasks, indicating enhanced optimism.
A new study explores how young children perceive fairness and act on it, revealing nuanced gender differences in sharing behaviors. Researchers found that girls tend to show more compassion in sharing, while boys are more competitive, especially with other boys.
A recent study finds that increased screen time is associated with higher levels of depression, anxiety, and attention issues among 9- and 10-year-olds. Following a diverse group over two years, researchers discovered that activities like video chatting, texting, and gaming were most strongly linked to depressive symptoms.
Hair turns grey due to a decrease in melanin production in hair follicles, a process influenced by both genetics and environmental factors like stress. Contrary to myths, plucking a grey hair won’t make more grow back, and hair can’t turn grey overnight.
Scientists have identified how genetic variants influence the risk of neurological and psychiatric disorders, including schizophrenia and autism. Using live neural cells and DNA sequencing, researchers discovered thousands of "non-coding" genetic variants with context-dependent functions, activated during brain development.
A new study reveals that inflammation and immune system activation are closely linked to major depressive disorder (MDD), particularly in those resistant to standard antidepressants. Researchers analyzed gene expression in people with depression, finding increased immune-related gene activity, especially in those with higher inflammation.
A recent review highlights the potential of liver X receptor beta (LXRβ) as a target for treating depression and anxiety. Known for regulating cholesterol, LXRβ is emerging as a key player in mental health, with research showing its role in balancing neurotransmission and enhancing cognitive function.
Researchers analyzed AI-generated and human-written college admissions essays, finding that AI-generated essays resemble those written by male students from privileged backgrounds. AI essays tended to use longer words and exhibited less variety in writing style than human essays, particularly resembling essays from private school applicants. The study highlights concerns about the use of AI in crafting admissions essays, as AI may dilute a student’s authentic voice. Students are encouraged to use AI as a tool to enhance, not replace, their personal narrative in writing.
New research has pinpointed the specific brain region and neuron type responsible for reducing anxiety using the psychedelic drug DOI, without triggering hallucinations. The study revealed that DOI targets serotonin2A receptors on parvalbumin-positive neurons in the ventral hippocampus, decreasing anxiety behaviors in animal models.
A new study reveals that auditory hallucinations in schizophrenia may be caused by two faulty brain processes: a failed suppression of self-generated sounds and an overactive response to internal noises. The research showed that patients with hallucinations had a "broken" corollary discharge and an enhanced response to unintended sounds, compared to those without hallucinations. These findings suggest that future treatments for auditory hallucinations could target these disrupted processes.
Research shows that when rating food for appeal or calorie content, judgments are influenced by the food choices we’ve made just before. This effect, known as serial dependence, causes people to rate the next food similarly to the previous one, whether it’s more appealing or less.
