Ocean Navigators Use Waves, Not Stars
18 Nov, 2025
Summary
- Marshallese sailors navigate oceans by feeling waves hitting their boats.
- An illusion can make people believe they look younger to recall memories.
- Self-affirmation boosts wellbeing; frequent ads engage the brain less.
Master navigators from the Marshall Islands possess an extraordinary ability to steer across vast oceans by interpreting the subtle sensations of waves impacting their vessels. This ancient technique, recently explored by researchers during a Pacific voyage, offers profound insights into human brain function and sensory perception. The findings highlight alternative navigation methods and their connection to cognitive processes.
In parallel, a novel psychological study investigates memory recall through a unique visual illusion. By tricking the brain into believing an individual appears younger, researchers aim to enhance access to long-term childhood memories. This approach explores the fascinating link between self-perception and our ability to retrieve past experiences.
Further psychological insights reveal that simple self-affirmation practices can significantly boost personal wellbeing. However, new research also indicates a counterintuitive effect of repeated public health messaging, suggesting that increased exposure can lead to diminished brain engagement with the information over time.
