Imagine a train standing at the platform, ready to depart. All the passengers have taken their seats, the conductors have checked the tickets, and the doors are ready to close—yet the train does not start moving. The reason: the train driver’s watch has stopped. Without a functioning time signal, the entire departure is canceled, even […]Imagine a train standing at the platform, ready to depart.

Unconscious, But Not Inactive: What Anesthesia Reveals About the Brain
Consciousness is one of the greatest mysteries of modern neuroscience. Every day, we shift between different states: we are awake, asleep, dreaming, or lose consciousness—for example, during general anesthesia. For a long time, it was assumed that an unconscious brain is largely inactive. The idea seemed obvious: if we perceive nothing, hear nothing, and have […]Consciousness is one of the greatest mysteries of modern neuroscience.

The Rhythm of the Seasons: How Chronobiology, Emotions, and the Environment Influence Our Moral Values
Most people are familiar with the idea that the seasons influence our mood. Many feel more energetic in the spring, enjoy the long days in the summer, and find winter to be a quieter or more contemplative time. What is less well known, however, is that our moral beliefs may also change over the course […]Most people are familiar with the idea that the seasons influence our mood.

Brown Fat: The Body’s Underrated Regulator
Researchers have found that the length of daylight hours influences the level of opioid receptors in brown adipose tissue. As daylight hours shorten, receptor activity increases. A similar phenomenon also occurs in the brain. Both phenomena help humans and animals adapt to seasonal changes. The Importance of Brown Fat As the season grows darker and […]Researchers have found that the length of daylight hours influences the level of opioid receptors in brown adipose tissue.

Oxygen as a Timekeeper: How Breathing Influences Our Internal Clock
For decades, the matter seemed clear: light regulates the body’s internal clock. In the morning, sunlight hits the retina, the brain stops producing melatonin, and the body switches to a state of wakefulness. In the evening, light intensity decreases, drowsiness sets in, and the body’s internal clock prepares the body for sleep and recovery. This […]For decades, the matter seemed clear: light regulates the body’s internal clock.
