Students 'jump into action' for better health

A new study from the University of Missouri shows Jump Into Action (JIA), a school-based physical activity program, is effective in changing unhealthy youth behaviors. JIA participants reported increased knowledge of health behaviors and adopted many of these behaviors, leading to improved nutrition and reduced screen time.

Wildlife Conservation Society study uncovers a predictable sequence toward coral reef collapse

A study by the Wildlife Conservation Society identified 8 changes that occur on coral reefs before they collapse due to overfishing. Researchers found a 'window' of maximum sustainable yield between 300-600 kilograms per hectare, but when fish stocks drop below this threshold, reef degradation accelerates.

Additives meant to protect vitamin C actually cause more harm

Researchers found that anti-caking agents in powdered vitamin C products can accelerate degradation, even protecting it from moisture. This is due to the chemical properties of these agents, which can absorb or repel water and lead to further reactions that lower the nutrient's stability.
