The urban heat island effect occurs when cities replace natural land cover with dense concentrations of pavement, buildings, and other surfaces that absorb and retain heat. Consequently, urban areas are often significantly warmer than their rural surroundings — sometimes by as much as 5°C. While this phenomenon is well-documented, its social consequences are frequently overlooked. Lower-income neighborhoods, which tend to have fewer trees and green spaces, bear a disproportionate burden of this heat, resulting in higher energy costs and elevated health risks for their residents.

Scientists have long debated whether creativity is a product of nature or nurture. Recent neuroimaging studies suggest that creative thinking relies on a network of brain regions — including areas associated with imagination, attention control, and memory — rather than a single "creative center." Notably, highly creative individuals show stronger connections between brain regions that do not typically communicate with each other in less creative individuals. This finding implies that creativity may be less about innate talent and more about cognitive flexibility — the ability to make unexpected connections between seemingly unrelated ideas. Educators who dismiss a student as "not creative" may, therefore, be overlooking a skill that can be systematically developed through practice.
