Researchers found distinct brain activity patterns in introverts and extroverts using PET scans. Introverts exhibit more internal processing, while extroverts show increased sensory processing.
Aging hamsters who received a new biological clock had their lifespan increased by 20%, proving the importance of circadian rhythms to health and longevity. Behavioural modifications, such as structured light-dark cycles, may achieve similar benefits in humans.
A new University of Delaware theory explains how good insect moms fiercely protect their young by fanning their wings and charging predators when all hopes are on a single batch of eggs. The semelparous insects, which lay a single clutch, defend their only genetic legacy to the death.
