#Aggression

A new study suggests that aggression can be learned through what we observe, not just what we experience directly. In a controlled animal experiment, researchers found that when male mice watched familiar peers attack intruder mice, the observers were more likely to display aggressive behavior later. The effect was tied to specific neurons in the amygdala, a brain region long known to regulate emotions and social behavior. Importantly, scientists could modulate this by turning those neurons up or down, which either amplified or suppressed later aggression. While the findings are in mice, they illuminate a neural pathway by which social context and familiarity shape how violence is learned and spread within groups.

A major new meta-analysis led by University of Pennsylvania researchers has found that taking omega-3 supplements—commonly available in fish oil capsules—can reduce aggressive behavior by up to 28%, offering a potentially simple, affordable, and safe way to address a key public health challenge. The study, synthesizing almost three decades of international research, is the strongest evidence yet supporting nutritional intervention to reduce aggression among people of all ages and backgrounds (ScienceAlert; Penn Today).

A broad meta-analysis from a leading U.S. university indicates that omega-3 supplements, commonly taken as fish oil, can cut aggressive behavior by up to 28%. Spanning nearly 30 years of international studies, the review provides some of the strongest evidence to date that nutrition can influence behavior across ages and backgrounds.

In Thailand, where concerns about mental well-being, school safety, and road behavior are rising, the findings offer a timely, low-cost approach that complements existing therapies. Linking nutrition with behavior in a culturally neutral framework resonates with Thai families seeking practical prevention strategies.

A startling new synthesis of neuroscience and public health research suggests that parasitic infections—especially Toxoplasma gondii, a protozoan commonly carried by cats—could be silently influencing human personality, impulsivity, and even levels of aggression. The article, published by Neuroscience News and based on the work of psychiatrists and neurobiologists, highlights mounting evidence that these microscopic invaders can manipulate the brain’s chemistry and immune system, with sweeping effects that might ripple through individual lives and, potentially, wider society (Neuroscience News).

A fresh synthesis of neuroscience and public health suggests a common parasite, Toxoplasma gondii, might subtly influence personality, impulsivity, and aggression. The work summarized by neuroscience outlets draws on psychiatrists and neurobiologists, highlighting how infection can alter brain chemistry and immune activity. The finding carries meaningful implications for individuals and Thai society.

Historically, parasites were seen as physical threats only. New evidence points to a subtler influence: these organisms may shape how people think and feel, including dopamine balance that governs reward and risk-taking. Research indicates a large share of older adults worldwide may be infected with Toxoplasma gondii, underscoring public health relevance. In Thailand, where cats are common, farming thrives, and dietary habits involve exposure to potential sources of infection, the issue is especially pertinent.
