The science behind tattoo aesthetics: Beauty perception

Tattoos, long a subject of cultural and artistic debate, have recently gained attention from scientists studying how people perceive beauty. This research investigates how tattoos affect our judgment of physical attractiveness. By manipulating images of male and female models to display varying degrees of tattoo coverage, researchers analyzed the responses

Dominance: How social rank affect brain health - a fishy study

Dominance: How social rank affect brain health - a fishy study

In social animals, stress from competing for dominance or coping with subordination can influence brain health by inducing oxidative stress. Oxidative stress occurs when an imbalance between free radicals and antioxidants in the body leads to cellular damage. In the brain, it contributes to aging, neurodegenerative diseases, and cognitive decline,

Predictions: How we anticipate others' actions

Our ability to predict others' behavior is essential in daily life. This complex skill allows us to navigate social interactions by anticipating what others might do, even when the situation is unclear. Recent research shows that the brain manages this complexity by forming multiple predictions about others' actions,

How ant brains use moonlight for navigation

How ant brains use moonlight for navigation

Ants use polarized light from both the sun and the moon to navigate. Polarized light, which is light waves vibrating in a specific direction, serves as a natural compass. Ants can detect this pattern and adjust their direction based on the orientation of the light. In this study, foragers responded

Signals from within. How the heart talks to the brain

Signals from within. How the heart talks to the brain

Interoception is the mind's ability to sense its internal state. While traditionally studied as a whole-body experience, researchers now suggest breaking it into specialized domains. One key domain, cardioception, focuses on how the brain perceives signals from the heart. This involves unique neural pathways and specialized structures that

Space week day 2: Safeguarding astronaut minds

Space week day 2: Safeguarding astronaut minds

As space missions extend into deep space, the psychological well-being of astronauts is just as vital as their physical and technical readiness. Space exploration has progressed far beyond the moon landings of 1969, with plans for missions like a +1,000-day journey to Mars. Astronauts then face even year-long missions
